High purity and high activity calcium oxide is widely used as an additive in the chemical industry
In the plastic industry, calcium oxide helps improve the processing flowability of plastics, reduce the viscosity of plastic melts, make plastics easier to form during processing, reduce processing energy consumption, and improve production efficiency. In the processing of polyvinyl chloride (PVC) plastics, the addition of calcium oxide can effectively improve their processing performance, making them easier to extrude, blow mold and other processing operations.
In the rubber industry, calcium oxide, as an active filler, can interact with rubber molecules to activate rubber molecular chains, thereby improving the tensile strength, tear strength, and wear resistance of rubber. Calcium oxide can serve as an effective reinforcing agent in both natural rubber and synthetic rubber, improving the quality and service life of rubber products. And calcium oxide participates in the vulcanization reaction of rubber, playing a regulatory role in the vulcanization process. It can affect the vulcanization characteristics such as vulcanization speed and degree, enabling rubber products to achieve ideal performance requirements.
During the coating preparation process, calcium oxide can undergo chemical reactions with film-forming substances in the coating, improving its adhesion, hardness, and water resistance. For example, adding calcium oxide to alkyd resin coatings can improve the adhesion of the coating to metal surfaces, resulting in better performance in metal protection.
