How to solve the problem of unpalatable powder when mixing silicone rubber?

Mixing is to evenly distribute the ingredients in the raw rubber to make mixed silicone rubber. After mixing, silica gel and compounding agents play physical and chemical roles at the same time, thus forming a new structure.

When mixing silicone rubber, there will be a problem of unpalatable powder. What is the reason for this problem? How to deal with it? Let me introduce it to you below:

reason:
1. The mixing dosage of silicone rubber structure is small.
2. The hydroxyl content in the structuring agent is too low
3. The molecular weight of raw rubber is high and the molecular weight distribution is too narrow.
4. There is slightly cross-linked silicone rubber in the mixed silicone rubber.
5. The amount of white carbon black and additives added is not proportional. 6. The kneading temperature is too low or the kneading temperature is too low.
deal with:
1. Add structural agent
2. Use raw silicone rubber with uniform molecular weight distribution.
3. When adding materials, add 4 in proportion to the structural agent and appropriately increase the starting or kneading temperature.
