The nature and use
of phosphite antioxidants in the field of chemical production raw materials
1. Introduction
phosphite antioxidants are an important kind of chemical production raw materials, widely used in plastics, rubber, grease and coatings and other industries. They have excellent oxidation resistance, which can effectively extend the service life of the product and improve the stability of the product. This article will detail the nature and use of phosphite antioxidants.
2. phosphite antioxidant properties
1. chemical structure: phosphite antioxidant is the main structural characteristics of the P-O-C bond, the phosphorus atom has unpaired electrons, so it has high reactivity.
2. Thermal stability: Phosphite antioxidants have good thermal stability and can be used at high temperatures.
3. Oxidation resistance: Phosphite antioxidants have good oxidation resistance, which can effectively inhibit the generation and growth of free radicals, thereby protecting the product from oxidative degradation.
3. phosphite antioxidant use
1. plastic industry: in the plastic processing, phosphite antioxidant can effectively prevent the oxidative degradation of plastic, improve the service life and stability of plastic. At the same time, they can also improve the processing performance of plastics and increase the strength and toughness of plastics.
2. Rubber industry: In the rubber processing process, phosphite antioxidants can prevent the aging of rubber, improve the wear resistance and crack resistance of rubber, and extend the service life of rubber products.
3. Oil industry: In the oil storage and processing process, phosphite antioxidant can effectively prevent the oxidation of oil rancidity, prolong the storage period and service life of oil.
4. Coating industry: In the process of coating preparation and use, phosphite antioxidants can prevent the oxidation and degradation of the coating, and improve the weather resistance and durability of the coating.
4. conclusion
phosphite antioxidant is a kind of important chemical production raw materials, with excellent oxidation resistance and thermal stability, widely used in plastics, rubber, grease and paint industries. By using phosphite antioxidants, the service life of the product can be effectively extended, the stability of the product can be improved, and the processing performance and service performance of the product can be improved. Therefore, in the actual production, according to the needs of different products and process conditions, select the appropriate phosphite antioxidant for use.
