Dry anti-friction coating on elastomer surface

Appropriately increase the hardness of rubber

In theory, increasing the hardness of natural rubber can enhance the rubber's ability to resist deformation, and the sealing ring and the contact surface can be in uniform contact under the action of stress, and the wear resistance is improved; generally, many natural rubber sealing ring processing companies usually increase the hardness of the rubber by increasing the amount of sulfur or the amount of reinforcing agent 2LLYY0903-SJ. It should be noted that the hardness of natural rubber sealing rings should not be too high, otherwise the elasticity and buffering effect of the sealing ring will be affected, and eventually the wear resistance will decrease.

2. Adjust rubber elasticity

In order to reduce the cost of rubber products, natural rubber product manufacturers will fill a large amount of rubber fillers, but excessive use of rubber fillers will lead to a decrease in the elasticity of the rubber. It is necessary to reasonably control the amount, appropriately increase the elasticity of natural rubber, reduce the viscosity and hysteresis of the rubber, reduce the friction coefficient, and improve the wear resistance of natural rubber seals.

3. Adjust the degree of vulcanization

Rubber product manufacturers should reasonably adjust the vulcanization system and vulcanization parameters of natural rubber seals according to the vulcanization performance characteristics of natural rubber, improve the degree of vulcanization, and ultimately achieve the purpose of improving the wear resistance of rubber seals.

4. Improve rubber tensile strength

When using natural rubber to produce rubber seals, using fine-particle rubber fillers in the formula can increase the intermolecular force, and by increasing the tensile strength and tensile stress of the rubber, the wear resistance of natural rubber can be increased to a certain extent.

5. Reduce the surface friction coefficient of natural rubber seals
