We’ll share you more information. The following are some of the ways Richon gives to prevent and solve rubber yellowing:
- Optimize the rubber formula: Choose rubber varieties with better aging resistance, such as silicone rubber, fluorine rubber, butyl rubber, etc., which have better high temperature resistance and aging resistance.
- Use of antioxidants: Add UV absorbers, antioxidants, stabilizers and other additives to rubber products, which can slow down or prevent the oxidation process of rubber.
- Control the vulcanization process: ensure that the vulcanization temperature and time are appropriate to avoid excessive temperature or too long time resulting in rubber oxidation.
- Avoid impurity pollution: strictly control the quality of raw materials, avoid mixing chemical or mechanical impurities, and reduce the introduction of harmful substances such as heavy metals.
- Physical protection: Use surface coating or treatment, add light shielding agent, add paraffin, etc., to reduce the influence of light and oxygen.
- Environmental control: During the storage and use of rubber products, avoid long-term exposure to sunlight, high temperature, humidity and other environments.
- Drying of raw materials: Ensure that rubber materials are strictly dried before processing to remove moisture, as moisture will accelerate the aging process of rubber.
- Nanotechnology application: The use of nanotechnology to improve the anti-aging properties of rubber, such as adding nanoparticles to improve the heat resistance, light resistance and oxygen resistance of rubber.
- Choice of resins and oils: Avoid using resins and oils that are susceptible to light and heat and discoloration.
- Pigment selection: Use pigments with high yellowing resistance and high temperature resistance, giving priority to inorganic pigments to reduce yellowing that may be caused by organic pigments.
- Synergistic effect of antioxidant: reasonable collocation of different types of antioxidant, using their synergistic effect to improve the anti-aging effect.
- Environmental protection and migration of antioxidants: Choose antioxidants that have little impact on the environment and are not easy to migrate to avoid polluting other materials.
- Regular testing: Regular quality testing of rubber products to discover and solve yellowing problems in time.
- Use weather-resistant materials: For rubber products that are often exposed to the outdoors, better weather-resistant materials can be used, such as ASA (acrylate-styrene-acrylate) and so on.
- Product component analysis: Through the analysis of product components, to provide basis for reducing the formula, optimize the production process.
- Technical system analysis: The use of advanced spectral analysis, thermal analysis, elemental analysis technology, to identify unknown ingredients, formula reduction, comparative analysis, process improvement.
Through the above measures, the yellowing process of rubber can be effectively delayed and the service life of rubber products can be extended.
