Compounding Temperature Parameter Of Two Roll Mill C

  • Home
  • Compounding Temperature Parameter Of Two Roll Mill C

Process conditions and influencing factors of NBR

The temperature of the front and rear cylinders should be kept at a temperature difference of 5 to 10 C to facilitate operation. For example, the natural rubber is easy to pack hot rollers, the front roller temperature should be higher than the rear roller, and the synthetic rubber is the opposite.
