The material aging of sealing rings is a complex process, which is affected by many factors, including temperature, humidity, chemical media, light, mechanical stress and so on. In order to delay the material aging time of the sealing ring, the following measures can be taken:
First, reasonable selection of sealing ring materials and specifications
Select according to the use environment: according to the ambient temperature, humidity, pressure and whether the sealing ring is exposed to corrosive substances, choose the appropriate sealing ring material. For example, in a strong corrosive environment, materials with higher corrosion resistance should be selected.
Consider the characteristics of the medium: according to the different sealing media, choose a sealing ring material compatible with it to avoid chemical reactions leading to aging of the material.
Second, standard installation and maintenance
Correct installation: Follow the instructions of the product or the guidance of the professional to ensure that the sealing ring is installed in place to avoid poor sealing or damage caused by too tight or too loose.
Regular inspection: Check the sealing ring regularly, and replace it in time if it is damaged, aged or deformed.
Proper maintenance: During use, keep the sealing ring clean and remove impurities and sludge to reduce the coefficient of friction and wear. For seals that require lubrication, select the appropriate lubricant and control the lubrication dose.
Third, optimize the working environment
Temperature control: Avoid long-term exposure to extreme high or low temperature environments to reduce deformation and aging caused by thermal expansion and contraction.
Humidity management: To maintain a relatively dry working environment, you can use desiccant or humidity regulation equipment to control the ambient humidity.
Reduce friction: By optimizing the structural design or adding lubricants, reduce the friction and wear of the sealing ring during the working process.
Fourth, add anti-aging agent
Antioxidants: Antioxidants are added to the sealing ring material to slow down the damage of oxidation to the material.
Other anti-aging agents: According to the specific use of the sealing ring environment and material characteristics, add other types of anti-aging agents, such as light stabilizer, heat stabilizer, etc.
5. Adopt new technologies and materials
New materials: With the development of materials science, new materials continue to emerge, such as materials with higher corrosion resistance, high temperature resistance and wear resistance, these new materials can be considered to make sealing rings.
Surface treatment technology: Special treatment of the sealing ring surface, such as spraying wear-resistant coating, chemical passivation, etc., to improve its corrosion resistance and wear resistance.
Through reasonable selection of sealing materials and specifications, standardized installation and maintenance, optimization of the working environment, addition of anti-aging agents and the use of new technologies and new materials and other measures, can effectively delay the material aging time of the sealing ring, improve its service life and sealing performance.
