Color Masterbatch ——Analysis Of Common Problems In Adding Color Masterbatch Production
- Nov 06, 2018 -

The process can be debugged as follows:


1. The temperature of the mixing chamber is slightly increased by the temperature of the drop port.


2. Apply a certain back pressure to the injection molding machine. If it is still not good after the above debugging, it may be the dispersibility or matching problem of the color masterbatch and the resin, and should be solved by contacting the masterbatch manufacturer.


3. After using a certain color masterbatch, the product appears to be easily broken. This may be due to poor diffusion and miscibility caused by the poor quality of the dispersant or auxiliary agent selected by the manufacturer, which affects the physical and mechanical properties of the product.


4. After using the ratio on the color master specification, the color is too dark (too shallow). Although this problem is simple, there are many possibilities, specifically:


4.1. The color masterbone has not been carefully tested, and the pigment is too little or too much;


4.2. The measurement is inaccurate in use, and there are a large number of phenomena that domestic enterprises, especially small and medium-sized enterprises, are arbitrarily measured;


4.3. There is a problem in the matching of the color masterbatch and the resin, which may be that the carrier of the color masterbatch is improperly selected, or the manufacturer may arbitrarily change the resin type;


4.4. Improper machine temperature, the color master stays in the machine for too long, the processing procedure: first check whether the resin type matches the color master, whether the metering is accurate, and then adjust the machine temperature or speed. The above check can adjust the color master in the machine. Liquidity, if there are still problems, contact the masterbatch manufacturer.
