Characteristics of PS sheet and comparison with other materials:
Environmental protection: recyclable, no harmful substances, no odor and no pollution, green and environmental protection.
Stability: Anti-oxidation, waterproof and moisture-proof, mildew-proof and moth-proof, effective flame retardant, long-lasting performance and so on. Although it is such an excellent PS sheet, but still need to pay attention to these things
1. The temperature of each section on the barrel of the PS sheet production equipment gradually increases from the feeding section to the junction between the barrel and the forming mold;
2. The temperature is controlled at 5-10℃;
3. The gap between PS sheets should be slightly less than or equal to the thickness of the board products, and the gap between PS sheets should be slightly smaller than the gap between the die lips on both sides;
4. Note that the sheet surface roughness R should not be greater than 0.2pm. When cleaning the roller surface, it is not allowed to scratch the roller surface with a hard steel knife. A copper knife should be used to clean the roller surface residue.
