How to Prevent Aging Failure of Rubber Seals
Rubber seal aging is the most common irreversible failure of silicone rubber seals. It can be effectively avoided through material optimization, structural improvement, standardized processing and scientific application management, greatly extending seal service life and reducing equipment leakage risks.
Optimize material selection: Select high-quality silicone rubber materials with excellent aging resistance, ozone resistance and high and low temperature resistance according to actual working conditions. Avoid unqualified rubber formulas and inferior raw materials; use matched vulcanizing agents and additives to improve the molecular stability of rubber products and slow down polymer degradation.
Standardize mold processing technology: Strictly control rubber compounding, uniform mixing and vulcanization exhaust processes to avoid internal defects. High-precision rubber seal mold manufacturing ensures stable product structure and surface finish, preventing premature aging caused by surface cracks and quality defects.
Optimize structural design: Design reasonable seal compression to avoid long-term excessive compression fatigue aging. Ensure good medium compatibility between silicone rubber seals and working media such as oil, acid and alkali to prevent aging and deterioration caused by chemical corrosion.
Standardize application and maintenance: Reduce long-term exposure of seals to high temperature, strong ultraviolet and ozone environments. Regularly inspect and replace aging sealing parts, avoid dry friction operation, and maintain a good lubrication environment for dynamic seals to delay aging failure.
