Silicone Sealing GasketThe Role, Mechanism, and Factors Influencing Sealing: The function of silicone sealing gaskets is to prevent leakage of the sealed medium, which can be categorized into interfacial leakage and penetration leakage. The causes of interfacial leakage are typically due to the relaxation of clamping force between sealing surfaces, aging, deformation, corrosion, wear, or burn damage of the sealing surfaces, as well as mechanical vibrations under operating conditions. Penetration leakage, on the other hand, is related to the material type and manufacturing method of the silicone sealing gasket, the nature of the sealed medium, and factors such as working pressure and temperature.
In theory, even if usingSilicone Seal WashersIt is also impossible to achieve complete contact between the sealing surfaces, eliminating any microscopic passages or gaps. These channels, although narrow, are still sufficiently large relative to the volume of fluid medium molecules. Consequently, completely blocking fluids at the edges of the sealed surfaces is unattainable; some fluid will inevitably seep into the space between the sealing surfaces, where complex fluid dynamics and thermodynamic processes occur. It is generally believed that once the fluid enters the fine and irregular gaps between the sealing surfaces, it will experience resistance losses during its flow, consuming its energy. Simultaneously, a stationary boundary layer will form on the walls of these gaps, making the narrow channels even narrower or completely obstructed, thereby preventing the fluid from continuing to flow into the sealed surfaces, achieving the purpose of sealing.
ImpactSilicone Sealing GasketThe factors affecting sealing mainly include the surface condition of the sealing surfaces, the contact width of the sealing surfaces, the properties of the fluid, the temperature of the fluid, the material of the silicone sealing gasket, the preload applied to the sealing surface, and the influence of external factors (mainly system vibration, deformation of connecting parts, and misalignment of installation position). To ensure reliable sealing, it is essential to carefully consider these factors, and the quality and selection of the silicone sealing gasket are also crucial.
