Solution During The Production Process

- Feb 25, 2020-

ASA color coextrusion is widely used in ASA synthetic resin tile industry due to its excellent weather resistance and excellent decoration.

It can maintain the stability of color and physical properties even after long-term exposure to ultraviolet, humidity, cold and hot harsh environment. It has been successfully applied to key projects such as the Beijing Olympic Games, the Shanghai World Expo and the Guangzhou Asian Games, making important contributions to the transformation of cities, energy conservation and emission reduction.

Adjustment methods in the process of production.

First, when encountering the problem of excessive ASA compounding on both sides of the resin tile, the solution:

- Reduce the temperature of the ASA extruder screw barrel 1, 2, 3, 4, and zone. The set value is in the range of 180 degrees-185 degrees.

- Slow down the screw speed of the ASA extruder appropriately.

Second, the ASA color is different. When producing resin tiles, the ASA extrusion speed can be adjusted up and down at any time, not fixed.

Third, adjustment methods when encountering the problem of resin tile surface coating:

- Increasing the upper temperature of the problem area of the hanger film (210 degrees-230 degrees) can be used as the scope of normal process debugging.

- Increase the screw speed of the ASA machine appropriately until the problem is solved.
