Ensure its cleanliness, extending its life, increase the aesthetic level. As we all know, the characteristics of color-coated steel in the course of making the color on the surface will have a scale, rust and other contaminants. It should be stored in a clean environment, to avoid the erosion of various corrosive media storage sites on the ground should be flat, and there is no hard object a sufficient load-bearing capacity of the building, outside usually galvanized hot galvanized plate and hot version, plus point, except furniture are hot galvanized plate and hot galvanized plate outer color steel coil prices, sometimes using galvanized sheet. Corrosive environment is low, usually hot galvanized plate hot galvanized plate 90 or 50, when the corrosive environment of medium, usually hot galvanized plate 140 or hot galvanized plate 75. Known as the iron and steel industry, it said food plays an important role in national economy. After years of development, the Chinese steel big country already is, but the big but not strong. Since 1996, China's steel production has caitu 10 consecutive years ranked first in the world. At the same time, Chinese steel production is still emphasis on high energy consumption, low value-added products, some of the high value-added steel is still dependent on imports. 2008 China's total exports of 59.23 million tons of steel, total exports amounted to $ 63.4 billion; total steel imports 15.43 million tons, total imports amounted to 23.4 billion US dollars, the average price of steel imports than exports of steel higher than 40%. Substrate using difference galvanized sheet and galvanized sheet: zinc and aluminum zinc alloy layer compared to relatively active chemical properties, corrosion resistance and therefore a greater difference. Outdoor test under the same conditions showed Buying Cai Gang Vol, galvanized plate galvanized sheet useful life of more than four times. (2) The surface paint material differences in surface paint resins include polyester resin (PE), polyester resin reinforced silicide (SMP) and polyvinylidene fluoride resin (PVDF). Conventional solvent coating system - polyester resin (PE): polyester resin paint (Regalar Polyester, abbreviated PE) is a conventional topcoat systems, such resin is not fat oleic influence Hebei Color volume, in Comparison of the performance characteristics superior. Coating with good flexibility, adhesion and workability. But PE coating for resistance to sunlight and coating powder resistance is not ideal, so you need to use PE coating subject to several restrictions, are generally used for air pollution is not serious, in industrial environments or polluted areas, its life relatively lower. General life of eight to ten years. Currently on the market use more color-coated, including Bao board, Wu steel and most of Taiwan, South Korea imported color steel plate, belonged PE coating. It is understood that, in accordance with requirements of the Regulations, China's steel industry to adjust the industrial structure, improve product quality, an important task is to focus on the development of key high-speed rail steel, high strength steel for cars, steel and high-grade power tool and die steel, special large forgings etc. steel products, support enterprises, scientific research units to carry out one million kilowatts of thermal power and nuclear power with a thick steel plate and high-pressure boiler tube caitu coating method is mainly for the three roll coating method, film method and powder coating method. Roll coating method is the most widely used process for the strip after the first cleaning, surface preparation, by roll coating liquid coating applied to the strip, a lower surface, and then into the curing oven heating and baking, curing, curing and then quenched by water cooling, hot air drying, complete treatment process. Color steel roll coating method for producing mainly for two and three-coat two baking-coat three-bake type. Current common production methods for the 2-coat two baking style. A typical color coating production line consists of five major components, namely the introduction of paragraph (unwinding, cutting neat, stitched, product material), pretreatment section (cleaning, chemical treatment), coating segment (primer, baked coated surface paint, baking, of which there back paint), post-processing section (for further processing, a foil, printing, embossing and pressure-type and the like), and a lead-out (the finished product rolling process).
