Key Factors for Rubber O-Ring Temperature

The key factor of rubber O-ring temperature The key factor of rubber seals O-ring is the application temperature, and high temperature will accelerate the aging of rubber materials. The higher the operating temperature, the greater the permanent deformation of the O-ring shrinkage. When the permanent deformation exceeds 40%, the O-ring loses its seal, resulting in leakage. Due to shrinkage and deformation, the initial stress values ​​formed in the O-ring rubber data will gradually land and subside with the aerodynamic process of the O-ring and the effects of temperature landing. The original shrinkage of O ring manufactures operating at sub-zero temperatures may decrease or subside completely due to the sharp temperature landing. O Generally, when using a sealing ring, try to choose an O ring with a large cross-section. In the same case, the volume of the O type sealing ring squeezed into the gap should be lower than its maximum value. Silicone sealing ring has an open porous material, which can adsorb a variety of substances, and is a good moisture-proof agent, absorbent and catalyst carrier. The adsorption of silica gel is usually physical adsorption, which can be regenerated and reused. Add acid to alkali metal silicate (such as sodium silicate) solution to acidify it, and then pour a certain amount of electrolyte for mixing, that is to produce silicate suspicious glue; or add acid or acid to strong sodium silicate solution Ammonium salt. In this case at -50~-60℃, the rubber material that is not resistant to low temperature will completely lose the initial stress; even for the rubber material that is resistant to low temperature, the initial stress will not exceed 25% of the initial stress at 20℃. This is because the original tightening of the O-ring depends on the expansion coefficient. Therefore, when choosing the original tightening amount, it must be ensured that there is still sufficient sealing capacity after the stress landing due to temperature landing during the stress landing process. For O ring manufactures working at subzero temperatures, special attention should be paid to the recovery index and deformation index of the rubber material. Generally speaking, in the design, try to ensure that the O-ring has a suitable working temperature, or use high- and low-temperature resistant O-ring materials to improve the service life. Silica gel products use silica gel as the basic raw material and are called silica gel products. Silica gel is a porous material of varying sizes that is moderately dried from a silicate binder. With open porous material, it can adsorb various substances, and it is a good moisture-proof agent, absorbent and catalyst carrier.
need huge investment, so it is important to shop with caution.
