The categories and development trend of color steel coil

Color steel coil is a kind of composite material, which is also called color coated steel sheet.steel coil manufacturers, It is made by stripping the organic coating after being continuously subjected to chemical transfer coating such as surface degreasing and phosphating on the production line.

The coating type of color steel coil can be divided into: polyester (PE), silicon modified polyester (SMP), polyvinylidene fluoride (PVDF), high weathering polyester (HDP), clinker sol.

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.

The categories and development trend of color steel coil

The development trend of color steel coil:

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, it has the characteristics of beauty, three-dimensionality and high strength, which makes the cold embossing production technology become the development trend.
