高品质的彩色涂层钢板

山东高端彩涂板生产厂家我们通常推荐与建筑使用和使用寿命相匹配的涂料、涂料和基材。
彩涂钢板是由热镀钢板或铝锌钢板经表面脱脂、磷化、铬酸盐处理后，涂有机涂层并烘烤而成的产品。

We usually recommend coatings, coatings and substrates that match the building use and service life of the building.

Color coated steel sheet is a product made of hot-dip galvanized steel sheet or aluminum zinc plated steel plate after surface degreasing, phosphating and chromate treatment, coated with organic coating and baked.

The common coatings for color coated steel plate include polyester (PE), silicon modified resin (SMP), high weather resistant polyester (HDP), fluorocarbon (PVDF), etc. Color coated steel plate can be divided into general use and structural use. The specific brands are tdc51d, ts280gd, ts300gd, ts350gd and ts550gd.
The coating composition is generally two coating and two baking. The thickness of the front coating is more than or equal to 20 μ m, and the back coating is 5-12 μ M. The standards of color coated steel plate are: Chinese standard GB / t12754-2006, American ASTM a755 (zinc plating), ASTM a792 (aluminum zinc plating), European EN / 10169, Japan JIS g3322, South Korea KS d3506.
In general, we will pay special attention to the following properties of color coated steel sheet
Pencil hardness and gloss
● mechanical properties (yield strength, tensile strength, elongation)
Resistance to fading and chalking
Polyester (PE): good adhesion, wide range of formability and outdoor durability, medium chemical resistance.
Silicon modified polyester (SMP): the coating film has good hardness, wear resistance and heat resistance, and has good external durability and non pulverization, while glossy silicon modified polyester has limited retention and flexibility.
High resistance to UV and high durability of polyester.
Polyvinylidene fluoride (PVDF): with good formability and color retention, excellent outdoor durability and pulverization, solvent resistance. Color is limited.
