How to identify the quality of anticorrosive coating at the completion stage? After the decoration is completed, we can still identify the quality of the paint from the painted wall surface, mainly from the three aspects of drying time, scrub resistance and weather resistance, which are introduced below. How to identify the drying time of anti-corrosion coating quality. According to the national regulations, the surface drying (surface drying) time of coatings should be less than 2 hours, and some high-end coatings of big brands can be less than 1 hour. If the humidity and temperature reach certain suitable conditions, the surface drying time can also be shortened, and some can even be dried within half an hour, which is the characteristic of high-quality coatings. Scrub resistance. The judgment of scrub resistance is very simple. After painting, there are usually many processes to be done, such as installing wooden doors, floors, wardrobes, lamp hardware, sofa furniture, etc. Workers are liable to dirty the wall if they are careless. At this time, if they can wipe it off, it is basically qualified scrub resistance paint, otherwise it is suspected of false publicity. Weather resistance. When the paint is used, it needs to withstand the test of climate, such as the comprehensive damage caused by light, cold and hot, wind and rain, bacteria, etc. Its resistance is called weatherability. Due to the influence of temperature, humidity, bacteria and other factors, the coating with poor weather resistance will gradually change from shiny to dirty and dark over time, and may be accompanied by slight powder shedding, which is also the performance of poor coating quality. The quality of paint directly affects the quality of wall decoration, so the quality of paint must be paid attention to. The above mentioned methods to identify the quality of coatings can provide reference for everyone, and I hope they can be helpful.

How to quickly and accurately identify the quality of anti-corrosion coatings? Wall decoration is a very important link, which directly determines the style and final effect of the overall home decoration to a certain extent. Choosing a high-quality paint can help us avoid many unnecessary troubles. How to quickly and accurately identify the quality of anti-corrosion coatings? How to distinguish the quality of anti-corrosion coating In the process of home decoration, there are two situations for the purchase of coating: the owner buys it by himself or the construction party packs the materials. For the latter, we can only screen its quality during construction or after decoration. If the owner buys the goods himself, he must be careful. He should not only listen carefully to the salesperson's introduction, but also observe the following details. Look at the brand. Many home decoration professionals on the Internet often say not to pay too much attention to the brand of paint. In fact, it means to pay more attention to the essence of some paint on the basis of well-known brands. It does not mean that you can buy three no products without looking at the brand. What are the well-known paint brands on the market now? You can check them online before buying. We won't list them here (to avoid the suspicion of advertising). Remember to do some simple homework before buying. Look at the package. The so-called "packaging is the face of an enterprise", a powerful formal enterprise, because of the large sales volume of its products, its packaging printing volume is also large (less printing volume will lead to increased costs), so the packaging will look very delicate and formal. Look at the price. Regular brand coatings are produced according to the formula, and the price will not be too cheap; However, the coating with poor quality, some of which are jerry built, and some are even produced in small workshops, has low cost and is much cheaper than the regular coating. If there is a big difference between the paint price and the market price, it is better not to take advantage of small gains, otherwise it is easy to suffer big losses.

How to identify the quality of anti-corrosion coating? Anticorrosive coatings play an important role in paint coatings, which is an indispensable part of paint coatings. How to identify the quality of anti-corrosion coatings in 2020? How to identify the quality of anti-corrosion coating? 1. Detection of film adhesion Paint adhesion refers to the ability of the paint film to combine with the surface of the object to be coated or between coatings. General test standards for film adhesion include: GB/T1720-1979 Determination of Film Adhesion GB/T9286-1998 Cross cut Test of Paints and Varnishes Film GB/T5210-2006 Pull off Test of Paints and Varnishes Adhesion 2. Detection of film thickness The thick film standard of general anti-corrosion materials is about 100 μ m or 150 μ m. Heavy anti-corrosive coating shall be more than 300 μ m or more. Within the scope of this standard, its anti-corrosion effect is the best. Therefore, it is very important to detect the rear modulus. The test standards include: GB/T13452.2-2008 Determination of Paint and Varnish Film Thickness 3. Fineness test, that is, the fineness of solid matter in the paint. Fineness has great influence on film quality, film gloss, durability and storage stability of coatings. However, the finer the better, too small will affect the adhesion of the paint film. Test standards include: GB/T1724-1979 Determination of Coating Fineness GB/T6753.1-2007 Determination of Grinding Fineness of Paints, Varnishes and Printing Inks. Viscosity is used to indicate the viscosity of paint. Test standards include: GB/T2794-2013 Determination of adhesive viscosity Single cylinder rotary viscometer method GB/T9269-2009 Determination of paint viscosity Stommer viscometer method GB/T1723-1993 Determination of paint viscosity GB/T6753.4-1998 Determination of flow time of paints and varnishes with flow cup 5. Detection of nonvolatile content The nonvolatile content is also called solid content, Its content has a great relationship with the film quality and the use value of the paint. The test standards for nonvolatile content include: GB/T1725-2007 Determination of nonvolatile content of paints, varnishes and plastics

What are the requirements for anti-corrosion coating construction? Anticorrosive coating has a high anti rust effect of hot galvanizing, no need for primer, steel surface treatment, saving man hours, low cost, and effectively shortening the construction period. What are the requirements for anti-corrosion coating construction? Anticorrosive coating construction requirements 1. For work at heights, people are positioned at the height of the benchmark. When working in a building, if the operation is carried out on a shelf of more than 2m, it is called work at heights. In the coating work, the proportion of high falling and object strike accidents in high place work is the largest. Properly wearing helmets, safety belts or erecting safety nets as required can effectively avoid casualties. 2. In terms of electrical hazards, electrical hazards to painting operations not only cause fire and explosion, but also involve other safety issues. Electrical hazards include static electricity, lightning and electric shock. Static electricity can cause electric shock to the human body, resulting in combustion, explosion and other hazards. Lightning mainly refers to the damage to electrical equipment and control system and personal injury caused by lightning stroke. Electric shock accidents happen suddenly in the past, causing serious consequences in a very short time, endangering human life safety. 3. Chemical pollution and toxic injury: solvent coating products themselves have certain chemical hazards. In the work of Xuzhuang, it should be noted that the solvent and diluent in the paint may cause air pollution and harm human health. 4. Fire and explosion hazard solvent based coatings, as well as diluents used in painting operations, are mostly flammable and explosive materials, so the painting operation itself has hidden dangers of fire and explosion. The possible causes of fire and explosion are that electrostatic coating does not comply with the operating procedures, which is easy to generate spark; Waste paint, paint mist, waste rags of paint materials and solvents, etc. are not well kept, and they are easy to cause spontaneous combustion and ignition when stacked together; Improper selection or use of electrical equipment, or failure to timely repair after damage, insufficient explosion-proof grade, etc; Lightning disaster in thunderstorm season. 5. In terms of noise hazard, sound exceeding 100dB is strong noise. People working under this noise will temporarily reduce their hearing, but can recover it. However, hearing loss or even hearing loss caused by noise above 150dB cannot be recovered. Therefore, if it exceeds 85dB, protective measures must be taken. The noise level will vary according to the equipment type, location and location. Excessive noise needs to protect workers' hearing.

Anticorrosive coating refers to a class of liquid or solid materials that can form a film on the surface of an object under certain conditions to protect, decorate or perform other special functions (insulation, rust prevention, mold prevention, heat resistance, etc.). What fields will anticorrosive coating be generally used in? Anticorrosive coating application field ① emerging marine engineering: offshore facilities, coastal and bay structures, offshore oil drilling platforms; ② Modern transportation: highway guardrails, bridges, boats, containers, trains and railway facilities, automobiles, airport facilities; ③ Energy industry: hydraulic equipment, water tanks, gas tanks, oil refining equipment, oil storage equipment (oil pipes, oil tanks), power transmission and transformation equipment, nuclear power, coal mines; ④ Large industrial enterprises: paper making equipment, pharmaceutical equipment, food and chemical equipment, internal and external walls of metal containers, pipelines, storage tanks, mine smelting, cement plant equipment, floors, walls and cement components with corrosive media in chemical industry, steel, petrochemical plants; ⑤ Municipal facilities: gas pipeline and its facilities (such as gas holder), natural gas pipeline, drinking water facilities, garbage treatment equipment, etc;

What are the characteristics of anti-corrosion coatings? Anticorrosive coatings are used to prevent corrosion of metals and protect the service life of non-ferrous metals under general conditions. Many of them are not very clear about anti-corrosion coatings. What are the characteristics of anti-corrosion coatings? The characteristics of anti-corrosive coating can be used under harsh conditions and has a long anti-corrosion life. Heavy anti-corrosive coating can be used for 10 years or more in chemical atmosphere and marine environment, and can be used for more than 5 years even in acid, alkali, salt and solvent media and under certain temperature conditions. Thick film is an important symbol of heavy anti-corrosive coatings. The dry film thickness of general anti-corrosive coatings is about 100 μ m or 150 μ m, while the dry film thickness of heavy anti-corrosive coatings is more than 200 μ m or 300 μ m, and 500 μ m~1000 μ m. The corrosion resistance of ZS-711 coating was evaluated according to the U.S. NACE standard [PR-01-76 (1983) revised version ItenNo.53105, and the results showed that the coating successfully passed the 4000h salt spray test and 4000h damp heat test. The coating has weather resistance, aging resistance, radiation resistance, wear resistance, impact resistance, high temperature resistance (400 ℃~600 ℃), low temperature (- 60 ℃), and stable conductivity; Its resistivity can meet the anti-static requirements and ensure the long life of the coating. Strong adhesion The coating has strong adhesion to the substrate. The coating composition contains hydroxyl (- OH). The metal matrix provides positive ions, which can form chemical bond bonding. With the help of coupling agents in the coating, even covalent chain bonding can be achieved. Under the maintenance of the spatial network structure, the metals, metal oxide nanomaterials and rare earth oxide ultrafine powders contained in the coating composition help the coating to form a dense interface transition layer, so that its comprehensive thermodynamic properties match the matrix. It is efficient, convenient and easy to apply. It really realizes the self curing of inorganic coatings at room temperature. When the ambient temperature is 20 ℃ and the relative humidity is less than 85%, the surface drying time is 15min, and the solid drying time is 2h, which can ensure efficient construction, and achieve excellent salt fog resistance and aging resistance. The coating is self repairing. Local scratches caused by external forces can still be protected. The coating is not damaged by cutting and welding. Welding with coating will not affect the welding quality. Flexible method of use Inorganic polymer anticorrosive coating can be used alone or as anticorrosive lower layer coating in combination with organic paint. Single layer inorganic polymer anticorrosive coating can be used with epoxy system, acrylic system and polyurethane system when used as primer. ① Excellent anti-corrosion performance: good adhesion, excellent anti-corrosion performance and long service life. ② Excellent construction performance: it can be cured quickly at room temperature like conventional anti-corrosive coatings, which is easy to operate and can be operated by unskilled people (this is the main reason why chlorinated rubber heavy anti-corrosive coatings can be widely used). ③ Excellent environmental protection performance: the solid content of traditional solvent based anti-corrosive coating can only reach 50~60%, while the solid content of high solid heavy anti-corrosive coating can reach 70%~80%, or even 90%~100%. The solvent is reduced by nearly half, showing good environmental protection performance.

What are the types of conventional anti-corrosion coatings?

When purchasing decoration products, many people attach great importance to brands. Excellent brands not only guarantee the quality, but also show the taste of the decoration effect, so that others can see the uniqueness of home decoration. There are many brands of decoration products, which are inherited and developed in the market with their own characteristics. How should you choose? What is the difference between water-based paint and oil-based paint for automobiles? 1、 Difference between water-based paint and oil-based paint for automobiles 1. Whether there are harmful substances water-based paint: only water as diluent, harmless to human health; oily paint: banana water, Tianna water as diluent, containing a large number of harmful carcinogens such as benzene, xylene, etc. 2. Odor water-based paint: no harmful carcinogens, non-toxic and tasteless, After painting, you can move in to the oily paint: it contains a strong irritating smell, which is unbearable. The gas contains a lot of harmful substances, which harm human health. Generally, from January to February after use, the strong irritating smell will evaporate to basically tasteless, but a large number of harmful gases will still slow volatilize for 10-15 years. 3. Construction performance water-based paint: without special requirements, you can paint after simple training, It is very convenient to paint and repair by oneself. Oily paint: it can be painted only after professional training and practice. Because of its strong professionalism, it is difficult for ordinary people to paint well, Poor durability Paint film quality 5. Storage of water-based paint: nonflammable, without special storage requirements Oil paint: extremely flammable, must be stored separately according to fire control requirements II. What is the difference between water-based paint and oil paint 1. The thinner of water-based paint is water, and the oil paint is solvent. 2. The water-based paint is odorless, and the oil paint has a strong smell, mainly depending on where you use the water-based paint, its adhesion and hardness are good, The glossiness depends on whether you need bright or matte. The advantages of water-based wood paint and oil-based wood paint are as follows: 1. Environmental performance VOC content Needless to say, water-based wood paint has absolute advantages in this respect. water-based wood paint uses water as the solvent with ultra-low VOC content, and will not produce irritating odor during construction. Nitrocellulose paint and polyester paint add organic solvents, and their products contain benzene Toluene, xylene and its derivatives volatilize into the air during brushing and drying, directly stimulating human sensory organs and endangering the health of construction personnel. Therefore, oily wood paint has high organic volatile content and poor environmental protection performance. Long time ventilation is required after construction. 2. Safety In the process of storage and transportation, water-based wood coatings replace organic solvents with water, which is safe and nonflammable. It greatly reduces the risk factors and troubles in production and circulation. Benzene, xylene, acetone, solvent gasoline, and thinner contained in nitrocellulose coatings and polyester coatings are highly flammable, with potential safety hazards. 3. The moisture in the renovated convenient water-based wood paint evaporates quickly, so the surface of water-based wood paint dries quickly and is convenient for rapid construction. Because of its good environmental protection performance, it can be moved in after construction, reducing unnecessary trouble and saving time. Nitrocellulose paint and polyester paint will emit harmful gases during drying due to their organic solvents, Therefore, it takes a long time to ventilate and detoxify after renovation or decoration. It not only pollutes the air but also volatilizes unclean. The residual VOC will be harmful to people. Therefore, it needs to be avoided for a long time before it can be used, which is very troublesome. Because the problem of "homelessness" should also be considered for renovation. 3、 Related concepts 1. Water based paint Water based paint, water based antirust paint, water based steel paint, water based floor paint, water based wood paint, wood wax oil. It is harmless to human body and does not pollute the environment. The paint film is plump, crystal clear, flexible, and has the characteristics of water resistance, abrasion resistance, aging resistance, yellowing resistance, fast drying, and convenient use. 2.

The marking of suburban roads and highways is generally suitable for the use of hot-melt road reflective coatings. 3. Related concepts. 1. Marking is an important process in mechanical processing, widely used in single piece or small batch production. In casting enterprises, the first piece of a new mold is marked for inspection, which can timely find the problems in the size and shape of the casting, and take measures to avoid the loss caused by unqualified batches. According to the drawing and technical requirements, the operation process of drawing the processing boundary on the blank or semi-finished product with the marking tool, or drawing the point or line as the benchmark is called marking. There are two kinds of scribing: plane scribing and three-dimensional scribing. If it is only necessary to draw a line on one surface of the workpiece to clearly indicate the processing boundary, it is called plane marking; It is called stereoscopic lineation when it is necessary to draw lines on several surfaces of the workpiece at different angles (generally perpendicular to each other) to clearly indicate the processing boundary. The basic requirements for scribing are clear and symmetrical lines, accurate sizing and positioning dimensions. Since the scribed line has a certain width, the accuracy is generally required to reach 0.25-0.5mm. It should be noted that the machining accuracy of the workpiece cannot be completely determined by scribing, but should be ensured by measuring during the processing. 2.
