The sealing protection of T-shaped anti-slip anti-degumming ring involves all walks of life. This method is one of the indispensable processes in our manufacture of many items. The rubber sealing ring mainly plays a functional role, so it is only for product use, characteristics and various performance requirements. The rubber sealing ring is mainly protected by good clamping force and supporting force, so it is naturally important to control the shrinkage of the material.

1. The shrinkage rate of the rubber sealing ring changes with the increase of the rubber content density of the vulcanized silicone material, and the usual value is 0.0013.

2. The shrinkage rate of the rubber sealing ring becomes a saddle curve as the hardness of the rubber raw material increases.

3. The shrinkage rate of the silicone ring increases with the increase of the vulcanization temperature in the silicone processing plant, and the shrinkage rate increases by 0.1%-0.2% when the temperature rises by 10 degrees.

4. The shrinkage rate of rubber products also increases with the increase of raw material injection volume. When the raw material quality of rubber sealing ring is 5%-10%, the shrinkage rate is relatively stable.

5. The shrinkage of the rubber mixture in the calendering direction and the curing flow direction is greater than that in the vertical direction.

6. The better the plasticity of the composite material, the smaller the shrinkage; the higher the hardness of the compound, the smaller the shrinkage.

7. The more filler used, the smaller the shrinkage. The higher the gum content, the greater the shrinkage.

8. For a multi-hole 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 molding vulcanized products is smaller than that of molding.

10. The shrinkage rate of thin products (section thickness less than 3mm) is 0.2%~0.6% larger than that of thick products (section thickness greater than 10mm)

The sealing ring is suitable for installation on various mechanical equipment, and can be sealed in a static or moving state under specified temperature, pressure and different liquid and gas media. All kinds of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery and various instruments and meters. Rubber sealing rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion sealing, the sealing device rotates at low speed. The rubber sealing ring is generally installed in the rectangular section groove on the outer circle or the inner circle to play a sealing role. The rubber sealing ring can still play a good sealing and damping role in oil-resistant and wear-resistant environments.

The rubber sealing ring is placed in the inner chute of the water bottle cap, which mainly plays the role of waterproof sealing. It is mainly used for waterproof sealing and heat preservation of daily necessities such as water bottles, incubators, incubators, thermos cups, ovens, and magnetized cups.

Please choose a food-grade rubber sealing ring, which has good sealing performance, waterproof and leak-proof; it is completely non-toxic and tasteless; it does not deform when heated at high temperature and does not produce harmful substances; it has good tensile properties after special testing; it has passed food certification.
