White carbon black is a highly dispersed amorphous powder or flocculent powder, light in weight, with high electrical insulation, porosity and water absorption. The primary particle size is less than 3um, so the surface area is large, it has good reinforcement and thickening effect and good dispersion, suspension and vibration liquefaction characteristics. It has been widely used in plastics, rubber, papermaking, coatings, dyes and inks, etc. In several fields, especially in the rubber industry, silica takes the lead for its superior reinforcement and transparency.

Depending on the quality, it has different applications. Precipitated silica is mainly used in automotive rubber tires, pesticide feed, paint, toothpaste and other additives.

Precipitated silica is widely used as filling and reinforcing agent for rubber and plastics, ink thickener, paint and coating additive, synthetic grease and silicone grease thickener, flatting agent for leather industry, pesticide dispersant, paper filler, synthetic Resin (polyester resin, elastic polyurethane) additives, electrical and electronic insulation fillers and daily chemical raw materials and other industries. At the same time, it is used as an opening agent for polypropylene and non-toxic polyvinyl chloride plastic films, as well as an anti-caking agent and carrier for food, pesticides and medicines.

In resin-based composite materials, silica particles can be fully and evenly dispersed into the resin material, which greatly improves the strength, toughness and ductility of the epoxy resin material, improves wear resistance and improves the surface finish of the material, and improves Anti-aging properties. So as to achieve the purpose of comprehensively improving the performance of resin-based materials.

In the plastics industry, the use of white carbon black for light transmission and small particle size can make plastics denser. It not only improves its transparency, strength and toughness, but also significantly improves its waterproof performance, anti-aging performance, hardness and smoothness. For example: using nano-silica to modify ordinary plastic polypropylene, the main technical indicators (water absorption, insulation resistance, compression residual deformation, flexural strength, etc.) have reached or exceeded the performance indicators of engineering plastic nylon 6, and achieved Polypropylene railway accessories are used instead of nylon 6, and the product cost is greatly reduced, and its economic and social benefits are very significant.

In the rubber industry, it is usually necessary to add carbon black to the rubber compound to improve the strength, wear resistance and aging resistance, but the products are all black due to the addition of carbon black. For example, after adding a small amount of nano-silica to ordinary rubber, the strength, wear resistance and aging resistance of the product can reach or exceed that of high-grade rubber products, and the color can be kept unchanged for a long time. Tires are usually black, but the tires produced using nano-materials are not only bright in color, but also greatly improved in performance. The flexural performance of the tire side rubber has increased from 100,000 times to 500,000 times.

In home appliances such as color TVs, because carbon black is added to the material for electrostatic shielding, the home appliances are generally black and are called black home appliances. With the use of nano-silica, electrostatic shielding coatings can be developed, and the color of the coating can be further controlled. Black appliances will become colored appliances.

In the coating industry, nano-silica modified coatings have changed the shortcomings of previous products, and greatly improved such as poor suspension stability, poor thixotropy, poor weather resistance, and poor scrub resistance.

In the pigment and dye industry, it can overcome the shortcomings of organic pigments (dye) which have bright colors and strong tinting strength, but generally have poor light resistance, heat resistance, solvent resistance and migration resistance. The surface modification treatment of organic pigments (dye) by adding nano-silica not only greatly improves the anti-aging performance of the pigment (dye), but also improves the indicators such as brightness, hue and saturation to a certain extent. Dadi has broadened the grade and application range of organic pigments (dye).

Silica has a strong ability to reflect ultraviolet rays and good stability. It will not decompose or change color after being irradiated by ultraviolet rays, and will not react with other components in the formula. Therefore, it can be used in high-grade cosmetics, UV-resistant new organic glass, etc.
