彩涂板的应用细节不可忽视

彩涂板不同底漆的附着力、耐腐蚀性和耐腐蚀性不同。环氧树脂对基材具有优异的附着力和耐腐蚀性，但其耐腐蚀性能不如其他底漆。聚酯对基材具有优异的附着力和耐腐蚀性，但其耐腐蚀性能不如环氧树脂。

聚氨酯是一种优良的感应底漆。底漆通常由供应商根据生产工艺、应用、腐蚀环境和与面漆的匹配关系来选择。耐蚀性通常随涂层厚度的增加而增加。彩涂板涂层厚度应根据腐蚀、使用寿命和环境耐久性确定。
不同类型的面漆硬度、柔韧性、附着力和耐久性不同。聚酯是应用最广泛的涂料，具有优异的耐久性、优异的硬度和耐久性，且价格适中。 彩涂板硅改性聚酯具有较高的耐用性、光泽和保色性，但耐用性略有下降，耐候性高的聚酯具有较高的性价比。
聚偏氟乙烯（pvdf）具有优异的耐久性和耐久性，但其硬度较低，可获得多种颜色和价格较高的产品。彩涂板的面漆主要受涂层、环境腐蚀、使用寿命、耐久性、加工方法和变形程度的影响。

The adhesion, corrosion resistance and corrosion resistance of different primers are different. Epoxy resin has excellent adhesion and corrosion resistance to substrate, but its corrosion resistance is not as good as other primers. Polyester has excellent adhesion and corrosion resistance to substrate, but its corrosion resistance is not as good as epoxy resin.

Polyurethane is an excellent induction primer. The primer is usually selected by the supplier according to the production process, application, corrosion environment and matching relationship with the topcoat. Corrosion resistance usually increases with the increase of coating thickness. The coating thickness shall be determined based on corrosion, service life and environmental durability.
Different types of topcoats differ in hardness, flexibility, adhesion and durability. Polyester is the most widely used coating, with excellent durability, excellent hardness and durability, and moderate price. Silicon modified polyester has high durability, luster and color retention, but its durability is slightly reduced, and high weather resistant polyester has high cost performance.
Polyvinylidene fluoride (PVDF) has excellent durability and durability, but its hardness is low, it can be obtained with several colors and high price. The finishing coat of color coated plate is mainly affected by coating, environmental corrosion, service life, durability, processing method and deformation degree.
