Rubber production problems?

What factors are related to the vulcanization speed of rubber?
It should be related to the amount of vulcanizing agent, accelerator, etc., and also related to the rubber type and formula. By the way, adding silica will generally delay vulcanization. This post was last edited by Rosewood Xiangxie on 2009-3-4 15:48 ]
1. The size of delta MV 2. The drum temperature, rotation speed, and gap size of the kneading machine 3. The type of rubber, whether it is oiled glue or white glue, is different, for example: #1502 is different from 1712
I am engaged in carbon black. From my point of view, certain indicators of carbon black have a greater impact on the vulcanization speed of rubber, such as the PH value of carbon black, the 300% elongation of carbon black, etc.
Personally, I think it mainly depends on the dosage of vulcanizing agent and accelerator. If your company has a sulfide meter, you can conduct research on your rubber type yourself.
Take the reinforcing agent as an example. If it is acidic, it will increase the sulfur addition time. If it is alkaline, it will shorten the sulfur addition time. So the pH will affect the sulfur addition speed.
The main ones are vulcanizing agents and accelerators. A small impact can be huge. Even the same method may have an impact even if the person making the material is different. Don't talk about temperature and so on.
