What is the production process of silicone rubber compound?

1. Adjust the wheel base: The main process of rubber mixing is to adjust the wheel base of the rubber mixer to the middle of the high interval, because the solid collagen material just put in is a small piece, and the thickness is relatively high, so the wheel base of the working roll must be increased to 10 More than a millimeter ensures that the silicone material can be dispersed. In the early days, the silicone rubber mix reaches a certain temperature after the plastic particles are dispersed. When the raw materials are dispersed, the wheelbase is gradually reduced, and the raw materials are thoroughly combined with the vulcanization accelerator and the color glue. Just adjust to the track of the exit roller.

2. Raw material refining: The whole process of raw material refining is a relatively important process. In the production process, a roll of raw material must be continuously mixed for about 20 to 30 minutes before the raw material can be completely evenly mixed. To ensure that there are no material traces and quality problems in the subsequent production of silicone rubber products, the most important thing is the control problems in the operation process. Due to the limited width of the silicone rubber mixing machine, if you want to make a roll of raw materials, then Steady arm strength and fine technique are required.

3. Add color glue and vulcanization accelerator: add vulcanization accelerator and color glue when the raw material silicone rubber is uniform, and add it according to the weight ratio of the raw material, otherwise the raw material may appear color cast and vulcanized rubber. In the case of overcooking, the two can be added at the same time, but the amount of vulcanization accelerator must be controlled when adding the vulcanization accelerator. The rubber material must be turned quickly to make it mix quickly so that it cannot be allowed to generate static electricity due to friction and cause a fire. In addition, many customers add some quantum technology or other chemical substances to the silicone products, there are different powder, water and paste and so on.

4. Roller out: Roller out is also the most critical process for silicone rubber compounding manufacturers. The plastic particles of the product out of the roller are related to the ratio of rubber cutting after the event and the net weight ratio of the manufactured product, because the split type cutter head is used directly below the roller Cut off the two sides, and the weight of the plastic pellets is not light, so it must be collected at one time during the unwinding process. If the operator's hand strength is not enough during the unwinding process to cause the material to deviate or fall, then Had to do it all over again, and the unrolled tape didn't work.
