Ultrafine silica application

last edited:May 10,2023   

  Ultrafine silica is one of the important new inorganic materials and belongs to fine chemical products. Because of its fine particle size, it has high specific surface area, high adsorption force, high dispersibility and excellent stability, reinforcement, thickening and thixotropy. It plays a role in the construction industry, chemical industry, medicine, special materials, aerospace and other fields. It is a common name for nano-silica.

  1. Rubber: Superfine white carbon black is used as a reinforcing agent. Adding a small amount to rubber can significantly improve the tensile strength, wear resistance and aging resistance of rubber, which can exceed the level of high-grade rubber products.

  2. Plastics: Ultrafine white carbon black is used in plastic products, which can improve the quality of products, make them more convenient to process and shape, improve production efficiency, expand the scope of application, and make transparency, strength, toughness, anti-aging and other properties significantly improved.

  3. Coatings: Ultrafine silica used in coatings can improve anti-caking, anti-sagging, extinction, thickening, thixotropy, fluidization and other properties, and significantly improve the performance indicators of coatings.

  4. Anti-caking agent: As a flow aid, ultra-fine white carbon black can be added to powdered beverages and foods to improve fluidity and effectively prevent caking.

  5. Antibacterial field: Ultrafine white carbon black is non-toxic, non-polluting, physiologically inert, strong in adsorption, good in plasticity, anti-aging, and resistant to chemical corrosion, so it can be used as a carrier of fungicides.

  6. Pigment: Add superfine white carbon black to modify the surface of the pigment, which can improve the anti-aging, brightness, hue, saturation and other indicators of the pigment, and broaden the grade and application range of the pigment.

  7. Sealant: Ultra-fine silica is added to the sealant to form a silica structure on the surface, coupled with the hydrophobicity of silica, effectively inhibits the flow of colloid, accelerates the curing speed, and significantly improves the sealing effect.
