First, the use of high-quality substrates, the surface of the substrate, shape and dimensional accuracy requirements are increasing, outdoor use such as small zinc flat hot-dip galvanized steel coil, non-zinc flower flat galvanized steel coil timely The rise of zinc alloy hot-rolled coil; indoor use such as electro-galvanized steel coil, film cold-rolled sheet and aluminum coil.
Second, improve the pretreatment process and pretreatment fluid, the number of equipment is small, the cost is low to become the mainstream process, and the stability, corrosion resistance, and environmental performance of the pretreatment fluid are continuously improved.
Third, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastisol to obtain super color reproducibility, UV resistance, anti-sulfur dioxide, improve corrosion resistance; develop resistance to pollution and absorption Hot and other functional coatings.
Fourth, the unit equipment is more complete. Such as the use of new welding machine, a new roller coating machine, improve the curing oven, equipped with advanced automated instruments.
Fifth, because the cost of cold embossing is lower than that of hot embossing, and it has the characteristics of beauty, three-dimensionality, and high strength, cold embossing production technology has become a development trend.
Sixth, pay attention to product diversification, functionalization, and gentrification, such as deep-drawing color-coated panels, “pomelo skin” color coated panels, anti-static color coated panels, stain-resistant color coated panels, high heat-absorbing color coated panels Wait.
