1. If the auxiliary materials are not mixed evenly and the dispersion is not good, there will be blisters and lumps. When the blisters are broken, powder can be seen. Check whether the pressure, time, and temperature of the internal mixer exceed the standard. If the mixing is started, check whether the order of feeding and the number of times of thinning and passing are in line with the process.
2. It was originally mixed with water, or it was caused by too much water in the rainy season. It is recommended that the warehouse should have a humidity control device, not too humid.
3. It has been scorched.
4. Excessive rubber mixing will also cause foaming.
5. Air bubbles will be formed when air is pressed into the rubber mixture.
(Rubber products have high moisture or oil (resin is too high); the vulcanization temperature is too high or the local temperature is too high; the mixing process is uneven.
Solution:
1. Add additives that can improve the dispersion of carbon black!
2. It is also effective to increase the heating time of Duobotong, add some calcium oxide or even rubber powder
