佛山pcm预涂彩钢板阔叶绿色彩涂板 鞍钢0.5mm厚城市建设用
彩钢板涂层是冷轧钢板、镀锌钢板，进行表面化学处理后涂敷（辊涂）或复合有机薄膜（PVC膜等），再经烘烤固化而制成的产品。也有人把这种产品称之为“预辊涂彩钢板”。目前用于彩色涂层钢板的涂料种类有聚酯涂层(PE)、氟碳涂层(PVDF)、硅改性涂层(SMP)、高耐侯涂层(HDP)、丙稀酸涂层、聚氨脂涂层(PU)、塑料溶胶涂层(PVC)等。PE涂料对于材质有良好的附着性，彩涂钢板易于加工成型，价廉且产品多，颜色和光泽的选择余地大。聚酯涂料对耐紫外光性与涂膜耐粉化性，并不理想，因此PE涂料的使用仍需受到一些限制，一般用在空气污染不严重的地区或需多次成型加工的产品。Color steel plate coating is a product made of cold-rolled steel plate, galvanized steel plate, surface chemical treatment after coating (roll coating) or composite organic film (PVC film, etc.), and then after baking and curing products. Some people also call this product "pre-roll coated color steel plate". At present, the types of coatings used for color coating steel plate include polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high-resistant coating (HDP), propionized acid coating, polyurethane coating (PU), plastic sol coating (PVC), etc. PE coating for the material has a good attachment, color coated steel plate is easy to process and shape, cheap and many products, color and luster choice is large. Polester coating is not ideal for uv resistance and coating resistance, so the use of PE coating still needs to be subject to some restrictions, generally used in the air pollution is not serious areas or need multiple molding processing products.
