Some question of resin silicone in production(such as yellowing)

1. Yellowing The reason of yellowing have lots of.Now I can introco two reasons that is the temperature is too high and the additive is too much.

   the high temperature is occur in hydrolysis. sometimes the temperature of the hydrolysis is not controlled well, and the temperature will rise too fast, even to the reflux temperature.The person generally need control temperature well,and pay attention to the worker operation.

2. salinity:neutralize can produce salt.salinity is usually treated with filtration.

3. Moisture:Use water remover or distillation to solve.
