1.观察涂层厚度或
印花彩钢板涂层厚度及基材厚度。涂层厚度基本上只有0.02~0.03mm,涂层厚度往往小于0.15mm。劣质印刷彩钢板经常在钢基体和印刷彩钢板的涂层或涂层上作怪。通常减少钢基体的厚度,并在钢基体上多喷几层涂料或使用很厚的涂料,甚至市面上一些印刷彩色钢板的钢基体也只有0.15mm,但涂层为0.4mm。过薄的印刷彩钢板基材、过厚的涂层或涂层也会降低铝扣板的性能。
2.观察印刷彩钢板的外露钢材,如型材,有无细密、灰色、暗色及杂质。一般来说,如果截面为细晶,则质量更高。
3.用手指轻弹印刷的彩钢板。材质好的彩钢印制板金属声明显清脆,材质差的彩钢印制板金属声沉闷不明显。这是区别彩钢印制板质量的重要标准之一。
Now there are too many categories of printed color steel plates, so many people will feel that the first two are big when choosing printed color steel plates. In fact, there is no need to worry about so many varieties. Just remember that it is according to the needs, where you use it and what effect you want to achieve. According to the needs, where you use it and what effect you want to achieve, The general principles are: less money, more work, economical, safe, reliable and beautiful. Household appliance board, fluorocarbon board and ultra thick board can be selected. Generally, they can be comprehensively considered according to the purpose, place of use, fire rating and desired effect.
1. Observe the thickness of the coating or coating of the printed color steel plate and the thickness of the substrate. The coating thickness is basically only 0.02 ~ 0.03mm, and the coating thickness is often less than 0.15mm. Poor quality printed color steel plates often do tricks on the steel substrate and the coating or coating of the printed color steel plate. Usually reduce the thickness of the steel substrate, and spray several more coatings on the steel substrate or use very thick coating, Even some printed color steel plate steel substrate on the market is only 0.15mm, but the coating is 0.4mm. Too thin printed color steel plate substrate, too thick coating or coating will also reduce the performance of aluminum gusset plate.
