PVC彩钢板卷材有哪些令人印象深刻的特性?

PVC彩钢板卷材彩涂板的生产工艺为两涂二干。为了保证彩涂产品的涂装质量,涂装前必须清除基材表面的油污、灰尘和铁锈,这是保证涂装工艺的第一步,也是保证彩涂产品质量的基础性工作。处理的目的是去除基材表面的防锈油、锈斑和灰尘,然后在干净的基材表面进行化学涂层处理,PVC彩钢板卷材形成以Cr6+和Cr3+为基本骨架的网状化学转化膜,从而提高基体与基体之间的附着力涂层,提高了基材的耐腐蚀性和涂层的耐久性。

PVC彩钢板卷材工作质量决定了涂层的质量,直接影响到涂层的柔韧性、抗冲击性等物理指标。它决定了颜色的涂层附着力

The production process of color coated plate is two coating and two drying. In order to ensure the coating quality of color coated products, it is necessary to remove oil, dust and rust on the surface of substrate before coating, which is the first step to ensure the coating process and the basic work to ensure the quality of color coated products. The purpose of the treatment is to remove the rust proof oil, rust spots and dust on the surface of the base material, and then chemical coating treatment is carried out on the clean substrate surface to form a network chemical conversion film with Cr6 + and Cr3 + as the basic framework, so as to increase the adhesion between the substrate and the coating, and improve the corrosion resistance of the substrate and the durability of the coating. The working quality determines the quality of coating, and directly affects the flexibility, impact resistance and other physical indicators of the coating. It determines the coating adhesion of color coated plate products. The purpose of initial coating, fine coating and curing is to apply the coating on the surface of the substrate and use heating method to volatilize the organic solvent of the coating, so that the organic coating and the substrate are closely combined.The product quality of color coated plate is not only determined by the basic properties of substrate and coating, but also depends on the production process and operation control
