Things to note in the process of mixing silicone rubber

There is a certain process flow during the production of mixed silicone rubber. Only by mastering every step of the production of this product can we further improve the product quality, so this is related to the matters that need to be paid attention to in the product's process flow. Yes, the following content will be explained in detail.
When mixing, the roller distance is small at first (~ and then gradually enlarged. Adding materials and operating sequence, mixing silicone rubber (roller), reinforcing filler, structure control agent, heat-resistant additive, colorant, etc., thin-pass unloading oven The heat-treated vulcanizing agent thin pass is left overnight for re-refining to produce flakes.
We need to pay attention to this
The roller speed ratio of the double-roller open mill is appropriate, with the fast roller at the back. The higher speed ratio causes Faster mixing and low speed ratio can make the film smooth.
The roller must be passed through cooling water, and the mixing temperature should be below ℃ to prevent the scorch of the mixed silicone rubber or the volatilization loss of the vulcanizing agent. .
The rubber compound for mixing silicone rubber can also be heat-treated in an oven without heat treatment. After adding heat-resistant additives, add vulcanizing agent and then thin it, leave it overnight for re-refining, and then leave it for a few days for re-refining and tablet use. The mixing time is ~ minutes (the specifications of the open mill are).
At the same time, if powdered peroxide is used directly when mixing silicone rubber, explosion-proof measures must be taken, and it is best to use paste peroxide. The above knowledge will be briefly explained here. After understanding this knowledge, everyone will make progress in production. At the same time, our professionals will continue to release the latest industry information. I believe there will be something you need in it. content.
