First, the use of high-quality substrate, the substrate surface, shape and size requirements are more and more high, outdoor use such as small zinc flower flat hot galvanized steel coil, zinc-free hot-dip galvanized steel coil and nowadays The rise of zinc alloy hot rolled coil; indoor use such as galvanized steel coil, film cold rolled sheet and aluminum coil.
Second, improve the pretreatment process and pretreatment liquid, the number of equipment, low cost to become the mainstream process, and constantly improve the stability of pretreatment solution, corrosion resistance, environmental performance.
Third, pay attention to the development of new coatings, the general polyester, polyvinylidene fluoride (PVDF) and plastic sol improved, access to super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; development of pollution, Hot and other functional coatings.
Fourth, the unit equipment is more perfect. Such as the use of new welding machine, a new roller coating machine, improve the curing furnace, equipped with advanced automated instruments.
Fifth, due to cold embossing than the cost of hot embossing, with a beautiful, three-dimensional, high strength characteristics, so that cold embossed production technology has become the development trend.
Sixth, pay attention to product diversification, functional, high-grade, such as deep impact type color coated plate, "grapefruit skin" color coated board, anti-static color coating board, color coating pollution resistant, high heat absorbing color coating plate, etc..http://www.dreamhouseowner.com/
