Product Details:

Color-coated rolls of high-durability polyester, i.e. (HDP), have excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good film adhesion, rich colors, and excellent cost performance. Polyvinylidene fluoride, i.e. (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, stain resistance, limited colors, and cost.

Coated steel plates are lightweight and beautiful, have good anti-corrosion properties, and can be directly processed. They provide a new type of raw material for the construction industry, shipbuilding industry, vehicle plate manufacturing industry, furniture industry, electrical industry, etc., playing a role in steel It has good effects such as replacing wood, efficient construction, saving energy, preventing pollution, and so on. The base material of coated plate coils can be cold-rolled or hot-dip electroplated steel.

Although the organic coating part of the coated plate roll has a good anti-corrosion effect, there are still some small gaps in the organic coating, and air and moisture may enter and cause the base material to rust. Therefore, the base material without coating is used. Color-coated sheet rolls made of raw materials have a short service life, and scratches can easily spread and cause the coating to peel off. Oil is applied to prevent rust. This oil must also be removed before color coating production.

The most commonly used pretreatment method now is the alkali solution degreasing method. The chemical conversion coating has two functions. One is to further improve the anti-rust ability, and the other is to improve the adhesion between the base material and the coating and improve the coating performance of the substrate. Color-coated steel plates are made of steel plates and galvanized steel as the base plate and are made through surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating in a continuous method (roller coating method), and baking and cooling. product. Coated steel plates are lightweight, beautiful and have good anti-corrosion properties, and can be directly processed. They are used in the construction and shipbuilding industries.
