Silicone Seal GasketThe Role, Mechanism, and Factors Affecting Sealing: The function of silicone sealing gaskets is to prevent the 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 of the silicone sealing gasket, its manufacturing method, the nature of the sealed medium, and factors such as working pressure and temperature.
In theory, even if usingSilicone Sealing GasketIt is also impossible to achieve complete contact between the sealing surfaces, eliminating any microscopic channels or gaps. These channels, although narrow, are still sufficiently large in comparison to the volume of fluid medium molecules. Therefore, completely blocking the fluid at the edges of the sealing surfaces is unattainable; some fluid will always infiltrate between the sealing surfaces, leading to complex fluid dynamics and thermodynamics processes. It is generally believed that when fluid enters the fine and irregular gaps between sealing surfaces, resistance losses are generated during its flow, which consume its energy. Simultaneously, stationary boundary layers form on the walls of these gaps, making the narrow channels even narrower or completely blocked, preventing the fluid from continuing to flow into the sealing surfaces, thereby achieving a seal.
ImpactSilicone Sealing GasketThe main factors affecting sealing include: the surface condition of the sealing surfaces, the contact width of the sealing surfaces, the nature 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 (primarily system vibration, deformation of connecting parts, and installation position offset). 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.
