很多人在购买彩涂板时,并不知道真正的好彩涂板和差彩涂板的具体区别,因为表面相似,而且一段时间不使用也不会有问题。在选择涂层时要考虑的因素很多,包括涂层类型、涂层厚度、涂层颜色和涂层光泽。此外,有时还应考虑涂层的底漆和背面涂层的要求。目前用于彩涂钢板的涂料有聚酯涂料(PE)、氟碳涂料(PVDF)、硅改性涂料(SMP)、高耐候涂料(HDP)、丙烯酸涂料、聚氨酯涂料(PU)、塑料溶胶涂料(PVC)等。

01常见涂层类型
关于彩涂板的知识,让您成为专家!
聚酯(PE,聚酯)
PE涂层对材料具有良好的附着力,彩涂钢板易于加工成型,价格低廉,产品种类多,色泽选择范围广。聚酯涂层对薄膜的抗紫外线和抗粉化性能并不理想。因此,PE涂料的使用仍需加以限制。一般用于空气污染不严重的地区或需要多次成型的产品。
适用行业
一般工业厂房及仓库对彩板本身无腐蚀性,对色板的耐腐蚀性、耐老化性要求不高。更注重厂房的实用性和性价比。
硅改性聚酯(SMP)
由于聚酯中含有活性基团-OH/-COOH,因此很容易与其他大分子和物质发生反应。为了提高聚乙烯的耐光性和粉化性能,采用保色性和耐热性优良的有机硅树脂进行变性反应,使聚乙烯的变性率在5%-50%之间。SMP具有更好的钢板耐久性,防腐寿命可达10-12年。当然,它的价格比PE高,e树脂对材料的附着力和加工性能都不理想。因此,SMP彩涂钢板不适用于需要多次成型加工的场合,多用于建筑屋顶和外墙。

Many people in the purchase of color coated board, do not know the real good color coated board and poor color coated board specific difference, because the surface is similar, and not used for a period of time will not be a problem. There are many factors to be considered in the selection of coating, including coating type, coating thickness, coating color and coating gloss. In addition, the requirements of primer and back coating of coating should be considered sometimes. At present, the coatings used for color coated steel plate include polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high weather resistant coating (HDP), acrylic acid coating, polyurethane coating (PU), plastic sol coating (PVC), etc.

01 common coating types
About the knowledge of color coated board, let you become an expert!
Polyester (PE, polyester)
PE coating has good adhesion to materials, color coated steel plate is easy to process and shape, low price and many products, and there is a wide choice of color and luster. Polyester coating is not ideal for UV resistance and powdering resistance of film. Therefore, the use of PE coating still needs to be restricted. It is generally used in areas where air pollution is not serious or products that need to be molded for many times.
Applicable industries
Ordinary industrial plants and warehouses and warehouses are not corrosive to the color boards themselves, and the requirements for corrosion resistance and aging resistance of color boards are not high. More consideration is given to the practicability and cost performance of factory buildings.
Silicon modified polyester (SMP)
Because polyester contains active group - OH / - COOH, it is easy to react with other macromolecules and substances. In order to improve the sunlight resistance and powdering property of PE, silicone resin with excellent color retention and heat resistance is used for denaturation reaction, and the denaturation ratio of PE can be between 5% - 50%. SMP provides better durability of steel plate, and its anti-corrosion life can be as long as 10-12 years. Of course, its price is higher than that of PE The adhesion and processability of e resin to the material are not ideal. Therefore, SMP color coated steel sheet is not suitable for the occasions requiring multiple molding and processing, and most of them are used for building roofs and external walls.
