Mechanical seal sealing material performance requirements1

Mechanical seal sealing material performance requirements The performance of the mechanical seal sealing material is an important factor to ensure effective sealing. The choice of sealing material, the main mechanical seal should be based on the working environment of the sealing element, such as operating temperature, working pressure, and the working medium used. Mechanical seals and movement methods, etc. The basic requirements of mechanical sealing materials are as follows: 1. Mechanical sealing materials have certain mechanical properties, such as tensile strength, elongation, etc.; 2. Mechanical sealing materials have appropriate elasticity and hardness, and small compression set; 3. Mechanical materials have resistance to High temperature and low temperature performance, no decomposition and softening at high temperature, and no hardening at low temperature; 4. The mechanical sealing material is compatible with the working medium, and does not produce swelling, decomposition, hardening, etc.; 5. The mechanical sealing material has good oxygen resistance and aging resistance , durable; 6. The mechanical sealing material is wear-resistant and does not corrode metal; 7. The mechanical sealing material is easy to form and process, and the price is low;
