Main types of 2.
The substrate of the color steel plate is cold-rolled substrate, hot-dip galvanized substrate and electro-galvanized substrate. Coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and plastisol. The surface state of color steel plate can be divided into coated plate, embossed plate and printed plate, color steel plate is widely used in construction appliances and transportation and other industries, for the construction industry is mainly used for steel structure factory building, airport, warehouse and refrigeration and other industrial and commercial buildings, such as the roof wall and door, civil construction using color steel plate less.
Difference with plastic steel
The difference between it and plastic steel is that the composition of the material is different, and the magnet can be sucked.
Strictly speaking, plastic steel and color steel in the metal characteristics and surface treatment can not be very good distinction, because the same; so the distinction between the market mainly in the profile structure.
magnet test
Because it is ordinary carbon steel material, magnet can suck. In addition, stainless steel is the product of adding chromium (greater than or equal to 13%) on the basis of low carbon steel, so the magnet cannot be sucked.
3. development trend
First, the high-quality substrate is adopted, and the requirements for the surface, shape and dimensional accuracy of the substrate are getting higher and higher. For outdoor use, such as small zinc-flowered flat hot-dip galvanized steel coils and zinc-free flat hot-dip galvanized steel coils, zinc-alloy hot-dip galvanized steel coils that rise in time; Indoor use such as electrogalvanized steel coils, film cold-rolled plates and aluminum coils.
Second, improve the pretreatment process and pretreatment liquid, the number of equipment is small, low cost has become the mainstream process, and continuously improve the stability, corrosion resistance and environmental protection performance of the pretreatment liquid.
Third, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastisol to obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, and improve corrosion resistance; develop pollution-resistant, heat-absorbing and other functional coatings.
Fourth, the unit equipment is more perfect. Such as the use of new welding machine, new roller coating machine, improve the curing furnace, the configuration of advanced automation instruments.
Fifth, due to the low cost of cold embossing than hot embossing, it has the characteristics of beauty, three-dimensional effect, and high strength, so that cold embossing production technology has become a development trend.
Sixth, pay attention to the diversification, functionalization, and high-grade products, such as deep-drawn color-coated boards, "grapefruit peel" color-coated boards, anti-static color-coated boards, pollution-resistant color-coated boards, and high-heat-absorbing color-coated boards.
4. characteristic performance
Color steel plate coating is cold rolled steel plate, galvanized steel plate, surface chemical treatment after coating (roller coating) or composite organic film (PVC film, etc.), and then baked and cured products. Some people also call this product "pre-roll color steel plate" and "plastic color steel plate". Color plate products are produced by manufacturers in continuous production lines, so they are also called color coated steel plates. Color steel plate not only has the high mechanical strength of steel material, easy to form the performance, but also has the good decoration and corrosion resistance of the coating material.
