What are the causes and solutions for the foaming of the conveyor belt during the production process?

   1. The mixing of the auxiliary materials is uneven, the dispersion is not good, and there will be blistering and blistering. Check whether the pressure and time of the mixer and the temperature exceed the standard. If it is open, it depends on whether the feeding sequence and the number of times of refining are in line with the process.

   2, the original mixed with water, or now is the original water content caused by the rainy season. It is recommended that the warehouse should have a humidity control device, not too humid.

  3, already burnt.

  4, the rubber overheating will also foam.

  5. Injecting air into the rubber compound will form bubbles (the rubber product has a large moisture or oil (the resin is too high); the vulcanization temperature is too high or the local temperature is too high; the compounding process is uneven.


  Solution:

  1. Add an additive that can increase the dispersion of carbon black!

  2, more thin pass to add some hot refining time, add some calcium oxide or even rubber powder also has effect
