The Color Steel Coil is a kind of composite material, also known as a color-coated steel plate. It is a product made of strip steel after continuous chemical transfer treatment, such as surface degreasing and phosphating on the production line. It is then coated with organic paint and baked. The Color Steel Coil is a composite material with the advantages of the steel plate and organic material. It has the mechanical strength and easy formability of steel plates and good decorative and corrosion resistance properties of organic materials. The coating types of color steel coils can be divided into polyester (PE), silicon-modified polyester (SMP), polyvinylidene fluoride (PVDF), high weather resistance polyester (HDP), and clinker sol. Color steel materials are divided into five categories: packaging, home appliances, building materials, optical materials, and decorative materials. Among them, the color steel materials for home appliances are the best and the most refined, and the production requirements are the highest. Although the production capacity of hot-dip galvanized substrates for building materials with the most significant amount is large, there is a lack of suitable substrates such as spangle-free flat hot-dip galvanized steel coils and zinc alloy coated steel coils; the variety and quality of domestic coatings cannot fully meet the demand, and imported coatings The high price reduces the competitiveness, and the plastic film required for the film color board still needs to rely on imports, and there is a lack of high-end color-coated boards with thick coating, functionality, high strength, and rich colors; the products are not standardized enough, resulting in a severe waste of resources, with a production capacity of 40,000 There are too many low-capacity units with less than 1 ton per year, which have problems in product quality and environmental resource protection; there are too many new color-coating units in the country, far exceeding market demand, resulting in low operating rates of many color-coating units, or even shutdown—Development trend. The use of high-quality substrates requires higher and higher requirements for the substrates’ surface, shape, and dimensional accuracy. For outdoor use, such as small spangle flat hot-dip galvanized steel coils, zinc-free flat hot-dip galvanized steel coils, and the emerging zinc Alloy hot-dip coils; indoor use, such as electro-galvanized steel coils, film-coated cold-rolled sheets, and aluminum sheet coils. Improve the pretreatment process and liquid, the number of equipment is small, and the cost is low to become the mainstream process. The stability, corrosion resistance, and environmental protection performance of the pretreatment liquid are continuously improved. Focus on developing new coatings, improve general polyester, polyvinylidene fluoride (PVDF), and plastisol, obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, and improve corrosion resistance; develop functions such as pollution resistance and heat absorption Sexual paint. The unit equipment is perfect. Such as new welding machines, new roller coating machines, perfect curing furnaces, and advanced automatic instruments. Because the cost of cold embossing is lower than that of hot embossing, and it has the characteristics of beauty, three-dimensional effect, and high strength, the production technology of cold embossing has become a development trend.
