Rubber O-rings have good corrosion resistance, high temperature resistance, and oxidation resistance, so they are used for sealing in many places. After being used for a period of time, many users will find that they will compress and deform. What are the reasons for compression deformation? ?Today the editor will answer this question.
1. Factors of sealing ring shrinkage and stretching amount
2. The relationship between temperature and the relaxation process of the sealing ring
Temperature has a great influence on the relaxation of the sealing ring. No matter which vulcanized rubber material is used, the embrittlement rate will be accelerated under the action of high temperature. The higher the temperature, the greater the probability of deformation, when the deformation exceeds 50%. If the sealing ring loses its sealing performance, leakage will occur.
3. The harm of material pressure to sealing ring deformation
