Common Issues and Solutions in ASA Production
ASA color co-extruded material, renowned for its exceptional weather resistance and outstanding decorative features, is extensively used in the ASA synthetic resin tile industry. Even when exposed to prolonged harsh conditions such as ultraviolet radiation, humidity, and extreme temperatures, it maintains stable color and physical performance. It has been successfully applied in key projects such as the Beijing Olympics, Shanghai World Expo, and Guangzhou Asian Games, making significant contributions to the transformation of city appearances and energy conservation efforts.
Adjustment Methods for ASA Synthetic Resin Tile Production Process:
- Excessive Compound of ASA on Both Sides of Resin Tile:
- Reduce the temperatures of zones 1, 2, 3, 4 of the ASA extruder screw barrel, with set values in the range of 180 to 185 degrees.
- Slightly decrease the ASA extruder screw speed, adjusting within a range of approximately 1 rotation based on on-site conditions.
- Variation in ASA Colors During Production:
- Adjust ASA extrusion speed as needed during the production of resin tiles. The extrusion speed is not fixed and can be adjusted up or down.
- Covering Issue on the Surface of Resin Tiles:
- Increase the upper-layer temperature in the problematic area of the clothing rack film (within the range of 210 to 230 degrees) as a normal process adjustment.
- Moderately increase the ASA machine screw speed until the issue is resolved.
