The Color Steel Roll adopts cutting-edge compound technology to integrate the steel with the bright and rich peritoneum, which combines the good performance of various materials, greatly improves the chemical stability of the material, and has more effective anti-rust and anti-corrosion properties. Color steel roll color steel not only has excellent quality in terms of flexibility, plasticity, pressure resistance, wear resistance, heat dissipation and high temperature resistance, but also highlights in terms of color, finish and feel. It is worth mentioning that color steel production All the raw materials used are non-polluting and pollution-free environmentally friendly materials, and the production process is completely dust-free, and it has high environmental protection characteristics both in production and in later use. Color steel materials are divided into five categories: packaging, home appliances, building materials, optical materials and decorative materials. Among them, the best and most fine craftsmanship of color steel materials for home appliances, the highest production requirements.
1. Although the hot-dip galvanizing substrate with the largest amount of building materials is currently in a large capacity, it lacks a good substrate such as a zinc-free flower flat hot-dip galvanized steel coil and a zinc alloy coated steel coil;
2. The variety and quality of domestic coatings can not fully meet the demand. The high price of imported coatings reduces the competitiveness. The plastic film required for the color film of the film still needs to rely on imports. It lacks high-grade color with thick coating, functionality, high strength and rich colors. Coated
3. The product is not standardized enough, resulting in serious waste of resources. There are too many low-capacity units with a capacity of 40,000 tons/year or less, and there are problems in product quality and environmental resource protection;
4. There are too many new color coating units in the country, which far exceeds the market demand. As a result, the operating rate of many color coating units is very low, and even the production is stopped.
First, the use of high-quality substrates, the surface, plate shape and dimensional accuracy requirements of the substrate are getting higher and higher, outdoor use such as small zinc flower flat hot-dip galvanized steel coil, zinc-free flower flat hot galvanized steel coil in time The rise of zinc alloy hot-dip coils; indoor use such as electro-galvanized steel coils, foil cold-rolled sheets and aluminum coils. Second, the improvement of the pretreatment process and the pretreatment liquid, the number of equipment is small, the cost is low, and the mainstream process is continuously improved, and the stability, corrosion resistance and environmental performance of the pretreatment liquid are continuously improved. Third, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastisol, obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; develop pollution resistance, suction Functional coatings such as heat. Fourth, the unit equipment is more complete. Such as the use of new welding machines, new roller coating machines, complete curing ovens, and advanced automation instruments. Fifth, because cold embossing has lower cost than hot embossing, Color steel roll has the characteristics of beauty, three-dimensionality and high strength, which makes the cold embossing production technology become the development trend.
