Today, the editor introduces a new kind of PVC color-coated rolls for building materials. Do you know what color-coated rolls are used for? The following editor will briefly analyze PVC color coated rolls. PVC color-coated rolls have good water resistance and chemical resistance.
The PVC color coated coil coating film is a thermoplastic resin with a high film thickness, which can provide good abrasion and processing formability of the steel coil, and can reduce the scratches on the surface of the steel coil during processing and handling. The coating film has excellent chemical resistance, salt water resistance, gas resistance and other special properties. It is generally used in coastal areas or chemical industrial areas with particularly severe corrosion conditions, aluminum electrolysis workshops, galvanizing workshops, etc., and in homes. Decoration.
Due to the protection of high film thickness, the corrosion protection period can reach 15-20 years in coastal areas, and it is currently widely used in Europe.
The heat resistance of PVC color-coated rolls is relatively weak. Special attention should be paid to long-term use at 70°C. Intermittent high temperature should not exceed 80°C. When used as a roof, those who are directly exposed to strong sunlight should try to choose light-colored series of colors. When processing and assembling PVC color-coated steel coils, special attention must be paid to the guarantee of trimming or punching parts, and they must be sealed with a sealing agent to avoid blistering and peeling of the PVC color-coated coil coating after long-term use. Generally, it is coated with silicone rubber sealant.
