1), Precipitated silica is commonly known as white carbon black, also known as hydrated silicic acid and light silica. It appears as a white, highly dispersed amorphous powder and is also processed into granules as a commercial product. The specific gravity is 2.319-2.653, and the melting point is 1750°C. Insoluble in water and most acids, it will become aggregated fine particles after absorbing moisture in the air. Soluble in caustic soda and hydrofluoric acid. It is stable to other chemicals, resistant to high temperatures, does not decompose, and does not burn. It has high electrical insulation, porosity, inner surface area, water absorption, and non-toxic
2), product features:
Adhesion, anti-adhesion, anti-caking, cohesion, controlled release, carrier, flow aid, improved printing effect, mechanical effect, special additives for thermoplastics, reinforcement, rheology control, whitening, hydrophobicity through surface modification White carbon black is easily soluble in butyl oil, and the use of butadiene rubber and plastic as reinforcing fillers will significantly improve the mechanical strength and tear resistance of the product. Due to different manufacturing methods, the physical and chemical properties and microstructure of silica will be different, so its application fields and application effects are also different.
3), product usage:
Good reinforcing agent for synthetic rubber, carbon black, precipitated silica, glass glue, sealant; precipitated silica (fire grade): This product is suitable for dry powder extinguisher such as fire-fighting ABC and BC; precipitated silica (Cot roller grade) Excellent filling and reinforcing agent for various industrial rubber rollers (rice milling rubber rollers, printing rubber rollers, transmission rubber rollers, special rubber rollers, etc.); precipitation method silica (pesticide grade) is used as a dry powder pesticide Carrier; white carbon black can be used as a filling material in polyethylene, polyene, epoxy resin and other materials, which can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness.
