Precipitated Silica

Precipitated Silica is a general term for white powder X ray amorphous silica and silicate products. It mainly refers to Precipitated Silica, fumed silica and ultrafine silica gel, and also includes powdered synthetic aluminum silicate and calcium silicate. Silica is a porous material and its composition can be expressed by SiO2.nH2O, in which nH20 exists in the form of surface hydroxyl. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid), high temperature resistant, nonflammable, tasteless, odorless, with good electrical insulation.

  • Rubber products

White carbon black is used in colored rubber products to replace carbon black for reinforcement to meet the needs of white or translucent products. White carbon black also has super tinting power, tear resistance, heat resistance and aging resistance, so it can replace part of carbon black in black rubber products, thereby producing high-quality rubber products, such as off-road tires, engineering tires, radial tires, etc. .

 

  • Agricultural chemicals

In chemicals, such as pesticides, spray fertilizers, etc., silica is used as a carrier or agricultural emulsion or disintegrant. It is used as a disintegrant in water-dispersible granules. The suspendability rate is used in WDG. It is recommended to increase the usage amount by 10%. about. It can maintain long-lasting efficacy because of its ultra-high adsorption capacity, easy suspension, good affinity and chemical stability. It maintains its hold for a long time even in rain, washout and hot conditions.

 

  • Daily chemical products

Transparent colored and opaque toothpastes using silica as base and abrasive. This type of toothpaste has good flexibility and dispersibility. The abrasive body is smooth, soft and has good corrosion resistance. It does not abrade the toothpaste tube body; it can make medicated toothpaste Maintain the stability of medicinal properties. In particular, it has good compatibility with hydroxides, which can avoid the disadvantages of calcium salts used as abrasives to produce insoluble salts.

 

  • Cementing agent

Used in adhesives made of natural rubber or synthetic rubber, it provides thixotropy and reinforcement. At the same time, it can also improve adhesion due to its stretchability, making it high quality and low price.

 

  • Anti-caking agent

Silica is used to improve free flow in products such as lawn fertilizers, fungicides, grinding wheel abrasives, laundry bleach, phenolic injection molding of methenamine, phenol and urea plastic products, rubber sulfur manufacturing and anti-caking. block mixture.

 

  • Papermaking filler

Using silica as paper filler can improve the ink penetration resistance and mechanical strength of paper, increase whiteness, and reduce unit weight. It can effectively achieve lightweight paper, reduce production costs and improve paper performance. In addition, it can also be used in many
