Wall decoration accounts for a large proportion. The main purpose of wall decoration is to protect the wall, beautify the wall environment, and make the decorated wall fresh, fresh and environmentally friendly. The main purpose of wall decoration is to protect the wall and beautify the indoor environment. The wall decoration of family decoration is the key point of decoration. What is the difference between shear wall and load-bearing wall? You may as well know it with me. 1、 The difference between shear wall and load-bearing wall 1. Shear wall is a wall made of reinforced concrete. The load-bearing wall refers to the wall supporting the weight of the upper floor, which may be reinforced concrete or brick concrete structure. 2. The load-bearing wall is the wall supporting the upper floor, and the shear wall can be used as a load-bearing wall or a non load-bearing wall! (Generally speaking, shear walls are load-bearing walls) 3. The walls with steel bars in the walls we see are shear walls, which are different from the load-bearing walls in brick concrete structures. If the houses without column frames may be brick concrete structures, the houses with brick concrete structures are also load-bearing walls, The black and white marks can be seen clearly. While the shear wall is a hidden wall, it is not easy to see. 2. The distinction between the load-bearing wall and the shear wall 1. The shear wall is a wall composed of reinforced concrete, and the load-bearing wall is a wall that supports the weight of the upper floor, which may be steel reinforced concrete or brick concrete structure. 2. The load-bearing wall is a wall that supports the upper floor, The shear wall may be a load-bearing wall or a non load-bearing wall! (Generally speaking, shear walls are load-bearing walls) Frame structure refers to the skeleton composed of columns, longitudinal beams, transverse beams, floors, etc. as a load-bearing structure, and the wall is an enclosure structure. Frame shear wall structure refers to the vertical load shared by the frame and shear wall; The frame bears 20%~30% of the horizontal load and the shear wall bears 70%~80% of the structure. The length of the shear wall is designed according to the standard of 50 mm per square meter of the building. The full shear wall structure is a structure that uses the internal wall (or internal and external walls) of the building as the load-bearing skeleton to bear the vertical load and horizontal load of the building. 3、 Related concept 1. Shear wall Shear wall is also called wind wall, seismic wall or structural wall. The walls in houses or structures mainly bear the horizontal load and vertical load (gravity) caused by wind load or earthquake action to prevent structural shear (shear) damage. Also called seismic wall, it is generally made of reinforced concrete. It is divided into plane shear wall and tube shear wall. Plane shear wall is used in reinforced concrete frame structure, rising slab structure and flat floor system. In order to increase the rigidity, strength and collapse resistance of the structure, reinforced concrete shear walls can be cast in situ or prefabricated in some parts. Cast in situ shear wall and surrounding beams and columns are poured at the same time, with good integrity. The cylinder shear wall is used in high-rise buildings, high-rise structures and suspended structures. It is surrounded by the partition walls of elevator halls, stairwells, equipment and auxiliary rooms. The cylinder walls are cast-in-place reinforced concrete walls, whose stiffness and strength can withstand greater horizontal loads than plane shear walls. According to the mechanical characteristics, walls can be divided into load-bearing walls and shear walls. The former mainly bears vertical loads, such as masonry walls; The latter mainly bears horizontal load. In the seismic fortification area, the horizontal load is mainly generated by the horizontal earthquake action, so the shear wall is sometimes called the seismic wall. According to structural materials, shear walls can be divided into steel plate shear walls, reinforced concrete shear walls and reinforced block shear walls. Among them, reinforced concrete shear wall is the most commonly used. 2. Load load refers to external forces and other factors that cause internal force and deformation of structures or components. Or it is used to refer to various direct actions exerted on the engineering structure to make the engineering structure or components produce effects. The common ones are: structural dead weight, floor live load, roof live load, roof area ash load, vehicle load, crane load, equipment dynamic load, wind, snow, ice, wave and other natural loads. 3. Cast in situ is suitable for building industrialization, which requires mold fixation, that is, by assembling formwork on site, and then pouring concrete.

When decorating the house, you will need to buy some other materials. For example, for the problem of corner lines, you need to measure accurately and prepare the corner lines, so as to achieve the perfect effect. What about the tile corner lines? What are the materials of ceramic tile feet? Let's share today. 1、 What are the materials of ceramic tile angle line? 1. Stainless steel angle line series steel resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. It is also called stainless acid resistant steel. In practical applications, steel resistant to weak corrosive media is often called stainless steel, The steel resistant to chemical medium corrosion is called acid resistant steel. The popularity of stainless steel external corner line is far lower than the first two due to its high price. The stainless steel external corner line can be divided into opening and sealing according to its appearance, The PVC ceramic tile external corner line has a wide range of popularity, large consumption, low price and wide consumption The defects of PVC are thermal stability, impact resistance, corrosion resistance and oxidation resistance. Both hard and soft PVC are prone to brittleness when aging during use. If DEHA is used, it will interfere with human endocrine, causing breast cancer in women, congenital defects in newborns, decreased number of male sperm, and even mental illness. 3 Aluminum alloy series is the general name of aluminum based alloys. The main alloy elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloys have low density, but relatively high strength, close to or more than high-quality steel, good plasticity, and can be processed into various profiles with excellent conductivity, thermal conductivity, and corrosion resistance. They are widely used in industry, and the amount of use is only second to steel What are the advantages of using ceramic tile corner lines? Ceramic tile corner lines are PVC, stainless steel, wood, and resin and quartz stone. The last one is the most expensive and is also the closest to ceramic tiles. Ceramic tile corner lines have the following advantages: 1. Simple construction, convenient and time-saving installation, and can save decoration time. 2. Relatively difficult to damage. 3. Protected by the external corner lines of ceramic tiles, the service life of ceramic tiles becomes longer. 4. Beautiful decoration, Eliminates the trouble of edge grinding. It can be used on the edge of the foundation line and the wall skirt to hide the rough edge of the ceramic tile. 5. In addition to PVC, there are aluminum alloy and stainless steel materials now. They are more selective, and the color is bright. The bright edges and corners are more three-dimensional. 6. It is easy to remove dust. 3. Related concepts. 1. External corner line External corner line (external corner line closing strip) It is a decorative line used for 90 ° convex corner and corner treatment of ceramic tiles. With the base plate as the face, it is made into a 90 ° sector arc on one side. The material is PVC, aluminum alloy and stainless steel. The external corner line is widely used because of its simple installation, low cost, effective protection of ceramic tiles and other advantages. 2. Corrosion (usually represented by?) is one of the two basic operators in mathematical morphology (the other is expansion). It was originally defined for binary images, and then expanded to gray-scale images and then to complete lattice. What are the advantages and disadvantages of the recommended ceramic tile external corner line? Why do so many people think tile corner lines are important?

The water-based curing agent has various varieties, superior performance, good quality, safety and environmental protection. In addition, consumers pay more attention to environmental protection, health and personality. Therefore, water-based curing agent is very popular. The quality gap of water-based curing agents on the market is large, and the advantages and disadvantages coexist. Therefore, how to distinguish water-based curing agents becomes particularly important. I hope this article can help you and avoid detours. 1、 What does water-based concrete curing agent mean? It is a kind of concrete curing agent with better adhesion than ordinary ones. It can be applied to a variety of epoxy resins and provide different hardening rates. It has low viscosity, low color, non flammable, easy to clean, and easy to use. Especially in wet concrete conditions, it has good adhesion and wear resistance. Concrete sealing hardener, concrete hardener CS or hardener HS, originated from the American CURECRETE Chemical Company's research and development of Ansaff Miracle products. In 1999, it was introduced into China by Wuxi Huacan Chemical Co., Ltd. and became its general distributor in China. There have been three generations of products in the Chinese market: the strength of concrete mainly comes from silicon Calcium silicate compound (C-S-H) generated by calcium under the action of water, C-S-H is the substance that plays a major role in the strength of concrete. Concrete sealing hardener CS is a kind of colorless transparent liquid material, which is convenient to use, non-toxic, incombustible, has strong permeability, and can permanently seal concrete, meeting all VOC rules. It is used for indoor and outdoor carborundum wear-resistant floor, terrazzo floor, raw slurry polishing floor, super flat floor It is suitable for factory workshops, warehouses, shopping malls, supermarkets, wharfs, airport runways, bridges, roads and other cement based places on the common cement floor, stone and other bases. II What is the difference between cement curing agent and water-based curing agent? There is no difference between cement curing agent and water-based curing agent. There is no difference between Nalut cement curing agent and Nalut water-based curing agent. Nalut cement curing agent or water-based curing agent can already be used as high-end concrete polishing floor or top concrete floor cement based seamless grinding floor. How much is the cost of cement curing agent? There are several factors that affect the price of cement curing agent. One is the price of cement curing agent or water-based curing agent materials, the second is the price of cement curing agent construction, and the third is the wages of construction workers. The price of Nalut cement curing agent or water-based curing agent is moderate. So far, five construction teams have cooperated with us, Making cement curing agent or water-based curing agent floor projects all over the country. 3. Related concepts 1. Concrete, referred to as "concrete (t 髇 g)": a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term "concrete" refers to the use of cement as cementitious material and sand and stone as aggregate; Cement concrete, also known as ordinary concrete, is mixed with water (including admixtures and admixtures) in a certain proportion and is widely used in civil engineering. 2. Curing agent Curing agent, also known as hardener, curing agent or setting agent, is a kind of substance or mixture that promotes or controls curing reaction. Resin curing is an irreversible change process of thermosetting resin through chemical reactions such as condensation, closed-loop, addition or catalysis. Curing is completed by adding curing (cross-linking) agent. Curing agent is an indispensable additive. Curing agent shall be added whether it is used as adhesive, coating or castable, otherwise the epoxy resin cannot be cured. The variety of curing agent has great influence on the mechanical properties, heat resistance, water resistance and corrosion resistance of the cured product. 3. Sealing (m? F? Ng) means tight sealing. From Xiao Qian's "Inspiration from Iowa": "She gave me a bag of sugar and a small box of sealed sweet juice." And Wen Tianxiang's "Approval and Judgment on Yang Xiaosan's Death in the Commission Screen": "The words are sealed, and suddenly go away, and people can get it if they don't realize it."

Roof waterproof coating is a kind of widely used interior decoration material. It is very popular because of its safety, environmental protection, convenient construction and low price. In order to meet the needs of different users, different occasions and different price levels, how much is the roof waterproof for 100 square meters? Let's have a look. 1、 How much is the roof waterproof for 100 square meters? How much is the roof waterproof? How much is the leveling? It should be considered from two perspectives, one is the material problem, and the other is the construction problem. Waterproof material. It depends on how many materials are used, whether they are non-standard materials or national standard materials. They are all made at a price of more than 10 yuan. Qualified, a course of material costs about 40 yuan. Take the traditional SBS modified asphalt roll as an example, from more than 100 yuan per roll to 600 yuan per roll. The price of labor and materials contracted by the construction team ranges from more than 20 yuan per square meter to 5, 60 yuan or even 70 yuan per square meter. The cost of materials accounts for 60~65%. Generally speaking, about 20 yuan and 30 yuan are non-standard products, that is, unqualified products. Construction method. There are two kinds of roofs: accessible roof and non accessible roof. Generally, the accessible roof is made of SBS modified asphalt waterproof coiled material, and the thickness is selected by yourself. Generally, the 3mm national standard material cost is about 28 yuan per square meter, plus the mortar protective layer. The thickness is reasonably determined on the premise of considering the load capacity. For non accessible roof, waterproof coiled material with sand surface can be selected, but mortar protective layer can be omitted. The price of 3mm national standard material is about 33 yuan per square meter. In terms of labor costs, it is better to purchase materials by yourself, and labor costs are calculated separately; If labor and materials are contracted, the price is generally 30-60 yuan/square meter. 2、 How much does it cost to apply waterproof adhesive on the roof for about 100 square meters? Because of long-term exposure to outdoor harsh weather environment, materials with good weather resistance must be used. Polyurethane waterproof coating is composed of polyurethane prepolymer A and curing agent B formed by a series of chemical reactions such as polyether and isocyanate. When used, A Component B is mixed evenly, and forms an elastic overall waterproof adhesive film after brushing and curing. Product features: 1. Easy coating, room temperature curing, and short surface drying time; 2. Strong adhesive force, large elongation and high tensile strength; 3. It can be constructed on irregular and complex base surface, with excellent integrity and reliable waterproof; 4. Cold and heat resistance, aging resistance, convenient construction; 5. It has certain corrosion resistance. Scope of application: 1. Underground buildings: subway, tunnel, basement, well pit, elevator pit, pipeline, concrete floor, etc; 2. Roof waterproofing: flat roof, sloping roof, planting surface, sloping roof of concrete, wood, steel, asbestos product structure 3, internal and external walls, retaining walls, toilets, kitchens, non edible pools, swimming pools, flower beds, outfalls, etc; 4. Expansion joints, construction joints, deformation joints, etc; 5. It can be used as anti-corrosion floor, anti-corrosion pool and pipeline external anti-corrosion. 3. Related concepts 1. Waterproof and waterproof are no longer a new topic. Waterproof can not be ignored in tunnels, bridges, dams, roads, buildings or our daily houses. At the same time, the electrical products used in our daily life also have waterproof and moisture-proof problems that must be faced directly. Source: Records of the Historian? Chronicle of the Zhou Dynasty: "Zhao Gong said, 'It's the name of Zhang. It's better to guard against the mouth of the people than against water.'" In Guoyu, it says, "Prevent Sichuan.". 2. Ceramic tile, also known as ceramic tile, is a kind of acid and alkali resistant ceramic or stone material formed by grinding, mixing, pressing, glazing and sintering of refractory metal oxides and semi metal oxides. Building or decorative materials are called ceramic tiles. Its raw materials are mostly mixed with clay, quartz sand, etc. Recommended solar room with no glass glue on the roof and no water leakage

With the development of the times, more and more people are buying houses. For ordinary people, they may decorate their houses once or twice in their lifetime, so they will be particularly careful when decorating. But what is adhesive? Now various distinctive products have appeared in the market. Do you want to know more about what adhesive is? Why don't you take a look with me. I hope it will be helpful to everyone. 1、 What is rubber adhesive? Adhesive is one of the most important auxiliary materials. It is widely used in packaging operations. Adhesive is a viscous substance, which can connect two separated materials together. There are many kinds of adhesives, which can be generally classified as follows: 1. According to the source of materials, ① natural adhesive. It comes from substances in nature, including starch Protein, dextrin, animal glue, shellac, hide glue, rosin and other biological adhesives; It also includes mineral binders such as asphalt. ② Artificial adhesive. This is a kind of artificial material, including inorganic adhesive such as water glass, and organic adhesive such as synthetic resin and synthetic rubber. 2. According to the use characteristics, ① water-soluble adhesive. Adhesive using water as solvent, mainly including starch, dextrin, polyvinyl alcohol, carboxymethyl cellulose, etc. ② Hot melt adhesive. It is a solid adhesive that can be used after melting the adhesive by heating. General thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc. ③ Solvent based adhesive: adhesive insoluble in water but soluble in some solvent, such as shellac, butyl rubber, etc. ④ Emulsion adhesive, mostly suspended in water, such as vinyl acetate resin, acrylic resin, chlorinated rubber, etc. ⑤ Solvent free liquid adhesive. It is viscous liquid at room temperature, such as epoxy resin, etc. 3. It can be divided into ① paper based material adhesive according to packaging materials, mainly including starch paste, dextrin, water glass, chemical paste, casein, etc. ② Plastic adhesives, mainly including solvent adhesives such as styrene butadiene rubber, polyurethane, nitrocellulose, polyvinyl acetate, etc; Water soluble adhesives such as ethylene vinyl acetate copolymer and ethylene acrylic acid copolymer; Emulsion adhesives such as vinyl acetate resin and acrylic resin; Hot melt adhesives made of thermoplastic resins such as polystyrene, polyurethane, polyacrylate, etc. ③ Wood adhesive, mainly including bone glue, skin glue, stick glue, casein, blood glue and other animal glue; It also includes phenolic resin adhesive, polyvinyl acetate resin adhesive, urea formaldehyde resin adhesive and other synthetic resin adhesive; It also includes vegetable gums such as bean glue. Adhesive adhesive is a general term for non-metallic materials that can combine one solid surface with another solid surface due to surface bonding and internal force (adhesion and cohesion, etc; Auxiliaries include curing agent, diluent, plasticizer, filler, coupling agent, initiator, thickener, antioxidant, polymerization inhibitor, stabilizer, complexing agent, emulsifier, etc. According to requirements and uses, they can also include flame retardant, foaming agent, defoamer, colorant, mildew inhibitor, etc. 2. The main agent and main agent are the main components of the adhesive, leading the adhesive bonding performance, At the same time, it is also an important symbol to distinguish the types of adhesives. The main agent is generally composed of one or two or even three polymers, which are required to have good adhesion and wettability. The substances that can be used as adhesives include: (1) natural polymers, such as starch, cellulose, tannin, arabic gum, sodium alginate and other vegetable adhesives, as well as bone glue, fish glue, blood protein glue Animal stickers such as casein and shellac (2) Synthetic resins are divided into thermosetting resins and thermoplastic resins. Thermosetting resins include epoxy, phenolic, unsaturated polyester, polyurethane, silicone, polyimide, bismaleimide, allyl resin, furan resin, amino resin, alkyd resin, etc; Thermoplastic resins, such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylic resin, nylon, polycarbonate, polyformaldehyde, thermoplastic polyester, polyphenylene ether, fluororesin, polyphenylene sulfide, polysulfone, polyketone, polyphenyl ester, liquid crystal polymer, and its modified resin or polymer alloy, are the most widely used adhesives (3) Rubber and elastomer. Rubber mainly includes neoprene, butyronitrile ethylene propylene rubber, fluororubber, polyisobutene, polysulfide rubber, natural rubber, chlorosulfonated polyethylene rubber, etc; Elastomer is mainly thermoplastic elastomer and polyurethane elastomer (4) In addition, there are also inorganic binders, such as silicate, phosphate and phosphoric acid copper oxide. 3. Additives In order to meet specific physical and chemical characteristics, various auxiliary components added are called additives. For example, in order to make the main binder form a mesh or body structure, and increase the cohesive strength of the adhesive layer, curing agents are added (they react with the main binder and produce cross-linking); The curing promoter or catalyst is added to accelerate the curing and reduce the reaction temperature; In order to improve the resistance to atmospheric aging, thermal aging, arc aging, ozone aging and other properties, antioxidant is added; Filler is added to endow adhesive with certain specific properties and reduce cost; Toughening agent is added to reduce the rigidity of adhesive layer and increase the toughness; In order to improve the processability, reduce viscosity, and extend the service life, diluents are added. 3. Related concepts 1. Adhesive adhesives, also known as adhesives and adhesives, were introduced by American Henry in 1742? Invented by Dr. Harry Coover. It refers to the materials that stick two objects together and use different adhesives according to the characteristics of the materials to be bonded (mainly the surface characteristics, such as roughness). The adhesive is actually the diluted resin, and the resin itself has viscosity. But some glue ingredients are: PVA, water, preservatives. 2. Resin resin usually refers to the organic polymer that has softening or melting range after being heated, and tends to flow under the action of external force when softening. It is solid, semi-solid and sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as raw material for plastic products processing is called resin.

When you have bought your house, the only thing you need to do is to decorate it. It's a pleasure to start shopping in various furniture markets and see various discounts online. Adhesive will definitely be used for decoration. Adhesive is a popular decoration material in recent years. But there are many kinds of adhesives on the market? I hope it can help you avoid detours and regret later. 1、 What are the types of adhesives? 1. According to the source of materials, natural adhesives are derived from natural substances, including starch, protein, dextrin, animal glue, shellac, hide glue, rosin and other biological adhesives; It also includes mineral binders such as asphalt. ② Artificial adhesive This is made of artificial materials, including inorganic adhesives such as water glass, as well as synthetic resin and synthetic rubber? Organic adhesives such as starch, dextrin, polyvinyl alcohol, carboxymethyl cellulose, etc Hot melt adhesive is a solid adhesive that can be used after melting the adhesive by heating. General thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc. ③ Solvent adhesive An adhesive that is insoluble in water but soluble in a certain solvent, such as shellac, butyl rubber, etc. ④ Emulsion adhesives are mostly suspended in water, such as vinyl acetate resin, acrylic resin, chlorinated rubber, etc. ⑤ The solvent-free liquid adhesive is in the form of viscous liquid at room temperature, such as epoxy resin, etc. The adhesive is the medium between the label material and the bonding substrate, and plays a connecting role. According to its characteristics, it can be divided into permanent and removable. It has a variety of formulations, suitable for different surfaces and different occasions. The adhesive is the most important component in the self-adhesive material technology, and is the key to the label application technology. 3 According to raw materials, ① the end of MS modified silane modified silane polymer is methoxysilane. ② The full name of polyurethane is polyurethane, which is the general name of macromolecular compounds containing repeated carbamate groups on the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compounds. ③ Silicones, commonly known as silicone oil or dimethyl silicone oil, with the molecular formula of (CH3) 3SiO (CH3) 2SiOnSi (CH3) 3, are polymers of organic silicon oxides, which are a series of polydimethylsiloxanes with different molecular weights. The viscosity increases with the increase of molecular weight. 2、 What kinds of glass adhesives are there 1. Classification of single and double components Silicone glass adhesive can be divided into two categories from the product packaging: single component and two-component. The curing of single component silicone adhesive is to change its physical properties by contacting water in the air; Two component silicone adhesive is divided into two groups, A and B. Either group alone cannot form curing, but once the two groups are mixed, curing will occur. One component silicone glass adhesive is common in the market Classification of acid-base properties According to the acid-base properties, silicone glass adhesive can be divided into acid adhesive and neutral adhesive. Acid glass adhesive is mainly used for general bonding between glass and other building materials. Neutral adhesive overcomes the characteristics of acid adhesive that corrodes metal materials and reacts with alkaline materials, so it has a wider application range, Its market price is slightly higher than that of acid adhesive. A special type of neutral glass adhesive in the market is silicone structural sealant. Because it is directly used for metal and glass structure or non structural bonding assembly of glass curtain walls, its quality requirements and product grade are the highest among glass adhesives, and its market price is also the highest. 3. Color classification The silicone glass adhesive has many colors, and the common colors are black, porcelain white Six kinds of transparent, silver grey, grey and bronze. Other colors can be customized; Weather resistant silicone sealant is used to seal joints on the surfaces of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. Primer is not required in most cases. Mold resistant silicone sealant is the trend in the future. Silicone glue with mold resistant effect has longer service life than ordinary glue, is more firm, and is not easy to fall off, especially suitable for some humid Environments prone to mildew, such as bathrooms and kitchens. 3. Relevant concepts? Invented by Dr. Harry Coover.

In recent years, the market of adhesives and adhesives is very popular, and many manufacturers of adhesives and adhesives have launched their own products. So we will pay great attention to the quality of products when we choose. Under many products, we don't know how to choose. How should we choose the products that are suitable for us? You may want to refer to the difference between adhesive and adhesive before choosing. Maybe you can find inspiration. Next, we will introduce the difference between adhesive and adhesive. 1、 The difference between adhesive and adhesive Chinese name: adhesive English name: pelletbinder Other name: binder Construction departments and daily life. Bonding agent is one of the most important auxiliary materials, which is widely used in packaging operations. Adhesive is a viscous substance, which can connect two separated materials with its viscous energy. Many kinds of adhesives are mainly used for building materials and some packaging to achieve the connection between things. 2、 The difference between white glue and nail free glue is mainly from their environmental protection and fixation strength, The odor free product is made of resin raw materials, On the surface, many manufacturers are hard to accept. Because they think the price is too high, but nail free glue is only an auxiliary material, so the price is high, and it is also acceptable, Pay attention to purchasing products from regular manufacturers, and do not covet cheap products, resulting in insufficient nail free glue capacity. 3. Nail free glue is a green and environment-friendly product without formaldehyde and odor, which is synthesized from resin raw materials. It can be bonded with any material, odorless, not harmful to the skin, and will never become black and moldy. After drying, it can be polished with paint There will be no looseness and shaking between wood materials, which is firm and safe, and the quality is guaranteed. 5. The use of nail free glue does not need to be like the glass glue construction process. It does not need to stick the glue all over the construction surface. The nail free glue can only be used at a few points. The amount is small, the construction time is short, the material cost is saved, and the cost is relatively reduced. 3. Related concepts: bonding It is a process method to connect two adhesive parts by using the mechanical binding force, physical adsorption force and chemical bonding force generated on the connection surface. Bonding is not only suitable for the same material, but also suitable for different materials. The bonding process is simple, without complicated process equipment, and the bonding operation does not need to be carried out under high temperature and pressure, so the bonded parts are not easy to deform, and the joint stress is evenly distributed. In general, the adhesive joint has good sealing, electrical insulation and corrosion resistance. Relevant recommendations High temperature adhesive that can bond metal to metal Difference between high temperature refractory paint and ordinary paint

During the decoration, our decoration budget is always overspent, which seems to be an ordinary thing in the decoration, but when you think about it, the overspent money is not worth it at all. So we must shop around when choosing decoration products. Since the three types of adhesives are widely used and have always been popular with consumers, what are the three types of adhesives? Let's have a look. 1、 There are many ways to classify the types of adhesives, which can be divided into thermosetting, hot-melt, room temperature curing, pressure sensitive, etc; It can be divided into structural, non structural or special adhesives according to the application object; The bonding forms can be divided into water soluble, water emulsion, solvent and various solid types. Synthetic chemists often like to classify adhesives according to the chemical composition of adhesives. 1. Thermoplastic cellulose esters, olefin polymers (polyvinyl acetate, polyvinyl alcohol, perchloroethylene, polyisobutylene, etc.), polyester, polyether, polyamide, polyacrylate A-cyanoacrylate, polyvinyl acetal, ethylene vinyl acetate copolymer, etc. 2. thermosetting epoxy resin, phenolic resin, urea formaldehyde resin, melamine formaldehyde resin, silicone resin, furan resin, unsaturated polyester, acrylic resin, polyimide, polyphenylimidazole, phenolic polyvinyl acetal, phenolic polyamide, phenolic epoxy resin Epoxy polyamide, etc. 3. Synthetic rubber chloroprene rubber, styrene butadiene rubber, butyl rubber, sodium butadiene rubber, isoprene rubber, polysulfide rubber, polyurethane rubber, chlorosulfonated polyethylene elastomer, silicone rubber, etc. 4. Rubber resin phenolic nitrile rubber, phenolic chloroprene rubber, phenolic polyurethane rubber, epoxy nitrile rubber, epoxy polysulfide rubber, etc. 2 What are the types and stability of adhesives? There are three types of adhesives widely used at present. 1. The soft monomer of the adhesive with acrylate as the main body is butyl acrylate, the softest is isooctyl acrylate, and the hard monomer is methyl methacrylate, styrene, acrylonitrile, etc. These adhesives have high transparency and are the most commonly used adhesives at present. 2 The hard monomers of adhesives with butadiene as the main body are styrene (styrene butadiene emulsion) and acrylonitrile (acrylonitrile butadiene emulsion), which are compounded with other polymers to increase the strength of the skin film. This kind of adhesive is soft to the touch, but it is easy to yellowing, cheap, and does not need to be baked and fixed. 3. Polyurethane adhesives are polymers formed by polymerization of polyisocyanate compounds with polyether or polyester containing active hydrogen atoms, If polyether polyurethane is polymerized with polyether, it has good hydrolysis resistance, soft hand feel, but poor light resistance and heat resistance. If polyester polyurethane is polymerized with polyester, it has good light resistance, heat resistance, good elasticity, but not hydrolysis resistance. Because of its good elasticity and softness, polyurethane adhesive will not be able to absorb dust in the air like acrylate adhesive, It has good color fastness and is suitable for printing knitted fabrics. Polyurethane adhesives can be divided into solvent type and water emulsion type. When solvent emulsion is used, if there is solvent in the baking oven, if toluene volatilizes, there must be good ventilation. If there is water emulsion, there must be no such problem. In addition to the above three categories, there are also adhesives with silicone elastomer, acetate acrylic (vinyl acetate and propylene acrylate copolymerization) adhesives, but they are rarely used. 4 Stability of adhesive emulsion The stability of adhesive emulsion is related to the color fastness. The emulsion particles should be controlled at 0.2 μ m, and their particle size distribution should be uniform. They should not have large particles and small particles at the same time, otherwise the friction fastness will be reduced. The method to determine whether the emulsion is good or bad is to observe the appearance of the emulsion. The gray white emulsion indicates that its particles are large, at least 5 μ m, The yellow emulsion indicates that the particles are very uneven. Generally, the particles are at least 2 μ m, and the blue emulsion indicates that the particles are about 1 μ m. The ideal adhesive should be a translucent emulsion with blue light, not milky white, indicating that the particle size is 0.2-1 μ m, and the particle size distribution range is narrow. The printing and dyeing factory should reject the adhesive with yellow light or gray milky white emulsion. 5 Improving the rubbing fastness of adhesives The rubbing fastness of pigment printing is the most troublesome thing. In the past, some organosilicon was often added to the printing paste, but the effect was not significant. Some people think that this is caused by the uneven size of paint particles, others think that it is caused by adhesives, because the rubbing fastness of the same paint using polyurethane adhesives can be qualified, However, the use of acrylate adhesive is not qualified, and the use of adhesives with different proportions varies. Of course, the coating particles have an impact. If the particle size is large, and the crystal form and particle size distribution are uneven, the friction fastness will certainly be reduced, but when the coating is unchanged, the adhesive plays a decisive role. The main factor determining the impact of adhesive on the friction fastness is the friction coefficient of the film, The smooth film has high rubbing fastness, and the fastness of polyacrylate adhesive with high content of soft monomer is worse than that with low content. 3、 Related concept 1. Phenolic aldehyde is the foam of phenol and formaldehyde. Formaldehyde is harmful to human body, and nearly 20% of the raw material in phenolic aldehyde is formaldehyde. Because of its molecular structure, phenolic resin cannot be well linked to each other. There are a lot of powdery substances, just like chalk, and a lot of dust falls off with a knife. So many manufacturers use a lot of glue to bond them together. Phenolic foam, known as the "king of thermal insulation materials", is a new generation of thermal insulation, fire prevention and sound insulation materials. 2. Epoxy refers to the addition of oxygen atoms in the middle of the carbon chain of organic matter, such as the most common ethylene oxide (CH2-O-CH2). Two carbon chains form a triangle together.

Compared with liquid and gas, solid has a relatively fixed volume, shape and hard texture. Solid is a macroscopic system composed of particles of order of 10 ^ 23, which is a complex multi-body system. A solid may be a crystal whose spatial arrangement is a regular lattice arrangement (such as metal and ice), or an amorphous body whose spatial arrangement is irregular (such as glass). Generally speaking, a solid is a macro object. An object can be called a solid only when it reaches a certain size, but there is no clear stipulation on its size. Physical properties of solids include odor, color, volume, density, melting point, boiling point, specific heat, morphology at room temperature (solid, liquid or gas), hardness, porosity, refractive index, etc.

During the decoration, our decoration budget is always overspent, which seems to be an ordinary thing in the decoration, but when you think about it, the overspent money is not worth it at all. So we must shop around when choosing decoration products.
