Main application areas of silica Silica is a highly dispersed amorphous powder or a flocculent powder, which is lightweight and has high electrical insulation, porosity, and water absorption. Its original particle size is less than 3um, so it has a large surface area, has good reinforcement and viscosity-increasing effects, and good dispersion, suspension, and vibration liquefaction characteristics. In several fields, especially in the rubber industry, white carbon black ranks first with its superior reinforcement and transparency.

According to different quality and different applications, the precipitation method white carbon black is mainly used for automobile rubber tires, pesticide feed, coatings, toothpaste and other additives.

Precipitated silica is widely used in rubber, plastics fillers, ink thickeners, paint and coating additives, synthetic greases and silicone thickeners, smoothing agents for the leather industry, pesticide dispersants, paper fillers, and synthetics. Additives for resins (polyester resins, flexible polyurethanes), insulation and fillers for electronics and electrical industries, and daily chemical raw materials. It is also used as an opening agent for polypropylene, non-toxic polyvinyl chloride plastic film and an anti-caking agent and carrier for food, pesticides and medicine.

In the resin-based composite material, the white carbon particles can be sufficiently and uniformly dispersed in the resin material, so that the strength, toughness and ductility of the epoxy resin material are greatly improved, the wear resistance is improved, and the surface finish of the material is improved. Anti-aging performance. So as to achieve the purpose of comprehensively improving the performance of resin-based materials.

In the plastic industry, the use of white carbon black for light transmission and small particle size can make plastics denser. Not only improves its transparency, strength, and toughness, but also its water resistance, aging resistance, hardness, and finish are significantly improved. For example: the use of nanometer white carbon black 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 to achieve Polypropylene railway fittings are used instead of nylon 6, the product cost has dropped significantly, and its economic and social benefits are very significant.

In the rubber industry, it is usually necessary to add carbon black to rubber compounds to improve strength, abrasion resistance and aging resistance, but the addition of carbon black makes the products black. For example, after adding a small amount of nano-white carbon black to ordinary rubber, the strength, abrasion resistance and aging resistance of the product have reached or exceeded the high-grade rubber products, and the color can be maintained for a long time. Tires are usually black, but tires made from nanomaterials are not only bright in color, but also greatly improved in performance, and the flex resistance of the tire side rubber has been increased from 100,000 times to 500,000 times.

In home appliances such as color TVs, carbon black is added to the materials for static shielding, so home appliances are generally black and are called black appliances. Using nanometer white carbon black, electrostatic shielding coatings can be developed, and the color of the coatings can be further controlled. Black appliances will become colored appliances.

In the coatings industry, nanometer white carbon modified coatings have changed the deficiencies of previous products, greatly improving such factors as poor suspension stability, poor thixotropy, poor weather resistance, and poor scrub resistance.

In the pigment and dye industries, although organic pigments (dyeing) materials have bright colors and strong tinting power, they are generally short of light, heat, solvents, and migration resistance. Adding nanometer white carbon black to the surface modification treatment of organic pigments (dyestuffs) not only greatly improves the anti-aging properties of pigments (dyestuffs), but also the brightness, hue and saturation are also improved to some extent. The earth has widened the grade and application range of organic pigments.

White carbon black has strong ability to reflect ultraviolet rays, good stability, does not decompose, does not change color when exposed to ultraviolet rays, and does not react with other components in the formula. Therefore, it can be used in advanced cosmetics, UV-resistant new organic glass, etc.
