The sealing protection of T-shaped non-slip anti-release rubber ring involves various industries
Jul 09,2024
1. The shrinkage rate of the rubber seal ring changes with the increase of the rubber content and density of the vulcanized silicone material, and the usual value is 0.0013.
2. The shrinkage rate of the rubber sealing ring changes to a saddle-shaped curve with the increase of the hardness of the rubber raw material.
3. The shrinkage rate of the silicone ring increases with the increase of the vulcanization temperature of the silicone processing plant. When the temperature is increased by 10 degrees, the shrinkage rate increases by 0.1-0.2%.
The shrinkage rate of rubber products also increases with the increase of raw material injection. When the quality of the rubber sealing ring material reaches 5-10%, the shrinkage rate is relatively stable.
5. The shrinkage rate of the rubber mixture in the rolling direction and the curing flow direction is greater than the shrinkage rate in the vertical direction.
6 the better the plasticity of the composite material, the smaller the shrinkage rate, the higher the hardness of the rubber material, the smaller the shrinkage rate.
The more filler used, the less shrinkage. The higher the binder content, the greater the shrinkage.
For the porous cavity mold, the shrinkage rate of the vulcanized silicone product in the middle cavity is greater than that of the vulcanized product in the edge cavity.
9. The shrinkage rate of injection molded vulcanized products is lower than that of molding.
10. The shrinkage rate of thin products (cross-sectional thickness less than 3mm) is 0.2% greater than that of thick products (cross-sectional thickness greater than 10mm) by 0.6%.
