First, high-quality substrates are used, and the requirements for the surface, shape and dimensional accuracy of the substrates are getting higher and higher. Outdoors such as small spangle flat hot-dip galvanized steel coils and non-spangle flat hot-dip galvanized steel coils are timely released. The rise of zinc alloy hot-dip coil; indoor use such as electro-galvanized steel coil, film cold-rolled sheet and aluminum coil.
Second, improve the pretreatment process and pretreatment solution, the number of equipment is small, and the cost is low to become the mainstream process, and the stability, corrosion resistance and environmental protection performance of the pretreatment solution are continuously improved.
Third, pay attention to the development of new coatings, improve general polyester, polyvinylidene fluoride (PVDF) and plastisol to obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, and improve corrosion resistance; Thermal and other functional coatings.
Fourth, the unit equipment is more complete. Such as the use of new welding machines, new roller coaters, perfect curing furnaces, and advanced automation instruments.
Fifth, because cold embossing is lower in cost than hot embossing, and has the characteristics of beauty, three-dimensionality, and high strength, cold embossing production technology has become a development trend.
Sixth, pay attention to the diversification, functionalization and high-grade of products, such as deep-drawing color-coated boards, "pomelo peel" color-coated boards, anti-static color-coated boards, pollution-resistant color-coated boards, and high heat-absorbing color-coated boards Wait.
