Building decoration materials are materials that integrate materials, technology, modeling design, color and aesthetics. It is a kind of building material with various varieties, fast renewal cycle, active development process and great development potential. The speed of its development, the number of varieties, the quality, the old and new styles, and the level of supporting facilities determine the level of building decoration, which is of great significance for beautifying urban and rural buildings and improving people's living and working environment. With the continuous improvement of our people's living standards and environmental quality, higher requirements have been put forward for building decoration materials. Therefore, how to organize the supporting production and supply of various decoration materials to meet the needs of the four modernizations is a very urgent task for China's building materials front. 1、 Since the 1980s, an industrial system with initial scale and complete varieties and categories has been established. There has been an upsurge in the development and introduction of various new building decoration materials: on the one hand, China has independently researched and developed a large number of new building decoration materials, on the other hand, it has introduced more than 2000 building decoration materials production technologies and equipment from abroad, The completion and operation of these production lines have brought the development level of building decoration materials in China closer to the advanced level. Wallpaper and wall cloth form an annual production capacity of 400 million m2; The plastic floor has formed an annual production capacity of 1.62m2; The annual production capacity of chemical fiber carpet is 60 million m2; The annual production capacity of plastic pipes is 450000 tons; The annual production capacity of plastic profile is 300000 tons; The annual production capacity of building coatings is 800000 tons; Building ceramics have an annual production capacity of 1.58 billion m2; Building and sanitary ceramics have an annual production capacity of 55 million pieces; The aluminum profile has an annual production capacity of 400000 tons. More than 4000 varieties have been developed, and an industrial system with relatively complete product categories has basically taken shape. 2、 The main problems are as follows: 1. The product upgrading ability is weak, the color is old, the grade is low, and the supporting ability is poor, which can not meet the needs of the market and competition. Foreign building decoration materials attach great importance to studying the needs of the market, studying the psychology of customers, and updating the patterns and varieties in time to meet the needs of users. For example, wallpaper and wall cloth are widely used as interior wall decoration materials abroad, and their decoration effect mainly depends on their patterns and colors. Wallpaper manufacturers in Europe, the United States, Japan and other developed industries abroad attach great importance to the renewal of patterns and colors. Hundreds of varieties and thousands of designs have been developed to meet the needs of the market. Foreign wallpapers and wallcoverings have reached a high degree of serialization and standardization, but they are still constantly researching and updating to launch better and more suitable products for users. After more than ten years of efforts, the varieties and patterns of domestic wallpaper and wall cloth have developed, but compared with foreign countries, there are few varieties of patterns and patterns, and the styles are also relatively old. The main reason is that domestic wallpaper manufacturers still lack high-quality pattern designers, and the pattern update cycle is too long. Therefore, the product has poor selectivity, can not meet the needs of higher levels, and is difficult to participate in market competition. 1/4 record number: 4 one page on the front page 1 2 3 4 the last page on the next page 2. The product quality is unstable, the product circulation market is chaotic, and the quality of domestic decoration materials is unstable. The reasons are various, but the main reason is that the production enterprises do not strictly follow their own processes, The process procedures and product standards were not carefully implemented, resulting in the profile of plastic steel doors and windows. The quality problems in some regions are mainly caused by some production enterprises not strictly following their own scientific processes and cutting corners on materials. For example, by increasing the amount of calcium carbonate and other means to reduce production costs, the mechanical properties of profiled materials are greatly reduced. The elastic modulus of rigid PVC plastic is low. In order to improve/increase the wind pressure resistance and deformation resistance of plastic steel windows, At a certain wind pressure and strength, the inner cavity of the window frame and sash must be added with reinforced steel. According to the standard drawing, the reinforced steel must be rolled into a certain shape with cold rolled steel plates with a thickness of no less than 1.2mm, and treated with aging and anti-corrosion treatment. However, some manufacturers do not strictly follow the requirements of the above standards for processing and treatment, and sell scrap iron and wooden bars instead of copper at a lower price. After use, many problems occurred, which seriously damaged the reputation of plastic steel doors and windows. 3. The development of product structure is unreasonable. Although China's new floor decoration materials have developed in recent years, there is still a big gap between China and developed foreign industries in terms of variety, grade and consumption. According to rough statistics, at present, the consumption ratio of various decorative materials in floor decoration in China is roughly as follows: ceramic wall and floor tiles account for 60%~65%, marble and granite floors account for about 10-12%, plastic floors account for about 16~20%, and wood floors account for 3~4%. The ratio of organic and inorganic decorative materials is 20:80, which is just the opposite of the types of materials used in industrial development, It shows that the industrial structure of ground decoration materials in China is not reasonable, and it is still a development path with high energy consumption, large transportation volume, and low production and construction efficiency. 3、 Development trend of environment-friendly materials 1. At present, the wood adhesive used for various kinds of wood-based panels produced in China is basically urea formaldehyde resin, which is polymerized by formaldehyde+urea, causing great pollution to family decoration and unable to move in within a few months. In fact, the slow release of formaldehyde lasts for 3-15 years, which pays for our health. The adhesive for formaldehyde free wood-based panels, which is made from plants through a special synthetic process, completely abandons the harmful substances such as formaldehyde and urea synthetic urea formaldehyde resin as wood adhesive, and the bonding strength fully meets the standard 2/4 Number of records: 4 One page on the front page 1 2 3 4 The last page of the next page series products have reached the European E0 level and Japanese Fc0 level standards. They are safe to use and are truly green and healthy products that consumers can trust. 2. The harm of low radioactivity stone to human body comes from two aspects: one is external radiation (external radiation); The other is internal radiation caused by radioactive elements in the human body. Under normal circumstances, the radiation we human beings receive is low dose radiation. The great harm of radioactivity to human body is mainly the "radon" produced by radioactive elements in the process of decay, which is what we call internal exposure. Radon is a radioactive element and a gas. If a person lives in an environment with high radon concentration for a long time, radon will deposit in the lungs, especially in the bronchi and epithelial tissues, and emit a large amount of radiation, thereby endangering human health. Uranium mine is an area with high radon concentration. In Europe, as early as 1937, it was found that the lung incidence of uranium miners was 28.7 times higher than that of ordinary people. 3. Green stone Green stone should be considered from the aspects of exploration, mining, processing, etc.: exploration: first of all, we should understand the regional geological conditions, and whether there is a professional geological team for exploration. The first is general survey, which should grasp the variety of stone, block size, general mining conditions, transportation, water and electricity, radioactivity level, etc. Mining: Before mining stone, material detection, analysis and radioactivity test should be carried out first, so as to lay the foundation for the next mining and application. Improving the yield of raw materials is also one of the important contents. Processing: Whether the equipment used in the processing is advanced is also one of the contents of stone greening, such as the large plate sawing processing equipment. At present, the frame sawing machine, the multi rope diamond bead saw and the large plate processing equipment equipped with belt or chain saw can achieve large processing size, high efficiency and long service life. 4. Environmental protection paint Environmental protection paint is no longer synonymous, water-based paint represented by latex paint is the current popular environmental protection paint. However, emulsion paint is mainly used for wall finishing, but it is not suitable for furniture that has been a hot topic in recent years, which makes non environmental solvent wood paint one of the main culprits of indoor air pollution. Recently, a water-based wood paint used for wooden furniture came into being. It uses water as the medium, non-toxic, tasteless, no environmental pollution, and the paint film is smooth and bright, which avoids the pungent smell of traditional wood paint and fully conforms to the development trend of environmental protection of paint. Multifunctional coatings are fully developed. 3/4 Number of records: 4 One page on the front page 1 2 3 4 The last page on the next page Today, modern coatings have a wide variety of functions, and their functions are also more and more the status quo of building decoration materials and the prospect of environmental protection materials Feng Yuyue from the School of Design and Arts of Henan University of Technology is comprehensive. Waterproof, fireproof, moisture-proof, mildew proof, anti-corrosion, and carbonization proof, coatings have become a home guard. The latex paint with its own waterproof technology is washable. However, ordinary latex paint will lose powder after multiple scrubbing. Now, the manufacturer has improved and strengthened the waterproof property on the basis of the original, making the latex paint film harder and the paint surface easier to clean. A new product of German Shield ceramic thermal insulation coating is a new force to enter the thermal insulation coating market recently. It is a water-based coating composed of extremely small vacuum ceramic microspheres and other environmentally friendly emulsions. It has strong adhesion with walls, metals, wood products, etc. It can achieve the purpose of heat insulation and heat preservation by directly coating about 0.3mm on the surface of the substrate. 5. Insect and mold resistant coatings Insect and mold resistant coatings are gradually entering the market. Insect and mold resistant coatings are mainly made by adding biologically toxic drugs on the premise of maintaining the decorative properties of coatings. Therefore, the key to the production of insect and mold resistant coatings is the insect and mold resistant agent that is harmless to human body. In recent years, insect and mold resistant coatings have entered the market in foreign countries, and are welcomed by consumers. In particular, it has a qualified market in the food industry and construction engineering. 4/4 Number of records: 4 Previous page of the first page 1 2 3 4 Last page of the next page
