Metal materials are used more and more in existing products, because metal materials can better reflect the quality of products and highlight brand values. In many metal materials, aluminum is easy to process and has good visual effects. Rich in surface treatment methods, the first to be adopted by various manufacturers, aluminum surface treatment is mainly divided into: sandblasting (the formation of matte pearl silver surface), polishing (form mirror), drawing (similar to the formation of a satin effect), plating (covering a Layer other metal), spray (cover other non-metallic coating).
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90Â°C. It begins to decompose at about 170Â°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
