What are the disadvantages of high PH value of silicone rubber for silica?
1. High PH indicates that it is alkaline, and the alkaline is in the range of 9--11, which is especially conducive to the vulcanization of rubber.
2. If it is too high, although vulcanization will also be used, it will make the surface of the colloid sticky.
3. It will also increase the viscosity of the colloid and reduce the elasticity.
