How to reduce the viscosity of the surface of the Automotive Wiring Harness Protection Sleeve?

The Automotive Wiring Harness Protection Sleeve is added to a double-roller rubber mixer or a closed kneader, gradually adding white carbon black and other additives to repeatedly refining evenly, and extruded according to the technical standards of industry products. The extruded products will stick together after being put together for a long time. The extruded Automotive Wiring Harness Protection Sleeve vulcanized with peroxide will still stick together after the tube is stored for a long time after two-stage vulcanization. What is the reason? Yes, is there any solution? Seeing that the surface of the pipe extruded by the peer company is frosted and matte, is it possible to reduce the surface viscosity of the extruded Automotive Wiring Harness Protection Sleeve?

1. After the Automotive Wiring Harness Protection Sleeve is extruded, add a release agent before secondary vulcanization.
2. The sandblasting on the surface of the Automotive Wiring Harness Protection Sleeve should be related to the extrusion mouth shape.
3. The main reason is the mixing ratio of silane coupling agent, hydroxyl silicone oil, zinc stearate and vulcanizing agent in the knitting sleeve, which needs to be solved by specifically designing the mixing knitting sleeve material ratio and mixing process.
4. If the viscosity of the Braided Sleeve is too high, you can adjust the formula in the next production, add more base material 107 and silicone oil, or add less meteorological silicone without changing the base material and silicone oil. The specific situation It depends on the properties of the required glue. At the same time, pay attention to the yield value of the calcium powder in the future production. Sometimes too high moisture content will also affect the viscosity.
