Silicon dioxide USES

White carbon black, also known as silica, is an inorganic compound that has a variety of uses. Its main application areas include:
1. Rubber products. White carbon black is used as a reinforcing agent in the rubber industry, especially to replace carbon black in colored rubber products, which is used to improve the strength, adhesion, tear resistance and heat and aging resistance of rubber products.
2. Agricultural chemicals. White carbon black is used in products such as pesticides and high-efficiency spraying fertilizers.
3. Daily chemical products. Such as toothpaste, in which white carbon black is used as filler and abrasive.
4. Binder. In the adhesive made of natural rubber or synthetic rubber, white carbon black plays an important role.
5. Cosmetics industry. As an oil absorbent and stabilizer, it helps to control oil on the skin surface while stabilizing cosmetic ingredients.
6. Resins and plastics. White carbon black is used as a filling material for polyethylene, polypropylene and other plastics to improve the moisture resistance and insulation properties of the resin.
7. Paint industry. As a matting agent, it is used to produce high-grade coatings with matte effect.
In addition, in the field of wind power generation, white carbon black is used to make adhesives for leaves, which has high stability and anti-settlement properties due to its strong hydrophobicity and nanoscale. In general, the wide application of white carbon black is mainly due to its characteristics of high temperature resistance, non-flammable, tasteless, rust-free and good electrical insulation
