Precipitated silica: also known as hydrated silica, active silica, precipitated silica and precipitated hydrated silica. English name: SilicaCAS RN: 14464-46-1 Formula: SiO2 * nH2O. The main application fields of precipitated silica is a highly dispersed form of silica is an amorphous powder or flocculent powder, lightweight, has high electrical insulation properties, porosity and water absorption. Its primary particle size of less than 3um, so a large surface area, with good reinforcement and thickening effect and good dispersion, suspension and vibration liquefaction properties, has been widely used in plastics, rubber, paper, paints, dyes and inks ten several areas, especially in the rubber industry, with its superior reinforcing silica and transparency at the top. According to different quality, with different applications, precipitated silica is mainly used in automotive rubber tires, pesticides feed, paints, toothpaste and other additives. Precipitated silica is widely used in rubber, plastics filling reinforcing agent, thickener ink, paint additives, synthetic grease and grease thickener, leather industry flatting agents, pesticides dispersant, paper fillers, synthetic additives, resins (polyester resin, elastic polyurethane), the electrical and electronic industry insulation insulation packing and household chemicals and other industries. Both as polypropylene, polyvinyl chloride plastic film is a non-toxic anti-caking agent, and a carrier opening agents and food, pesticide medicine. In the resin-based composite materials, silica particles can be fully and uniformly dispersed in the resin material, the epoxy resin material strength, toughness, ductility are greatly improved wear resistance and improve the surface finish of the material, improving anti-aging properties. Aim to achieve an overall improvement in the performance of resin-based material. In the plastics industry, the use of silica and light, small particle size, so that the plastic can be made more compact. Not only to improve its transparency, strength, toughness, and water resistance, aging resistance and hardness, finish has improved markedly. For example: the use of nano-silica modified ordinary plastic polypropylene, is the main technical indicators (water absorption, insulation resistance, compressive residual deformation, flexural strength, etc.) are met or exceeded performance engineering plastic nylon 6, to achieve a polypropylene, nylon 6 using alternative railway accessories, product costs dropped significantly, its economic and social benefits are very significant. In the rubber industry, are usually added to the carbon black in the rubber compound to be used to improve the strength, abrasion resistance and aging resistance, but the addition of such products are carbon black. After adding a small amount of nano-silica as ordinary rubber, product strength, abrasion resistance and anti-aging properties meet or exceed grade rubber products, and can keep the color long term. Tires usually black, but the use of nano-materials production tires not only colorful, but also greatly enhance the performance, tire rubber side bending performance increase by 100,000 times to 500,000 times. In the TV and other appliances, because the material must be added to the carbon black electrostatic shielding, so appliances are generally black, known as black appliances. The use of nano-silica can be developed electrostatic shielding paint, and further to control the paint color, black appliances will become colored appliances. In the paint industry, nano-silica modified coatings have changed less than previous products, such as poor greatly improved suspension stability, thixotropic poor, poor weather, poor scrub resistance. In pigments and dyes industry, organic pigments can be overcome (dye) material, although with bright colors and strong coloring power, but generally light, heat, solvent resistance and poor migration performance shortcomings. By adding nano-silica organic pigment (dye) material surface modification treatment, not only the Yen (dye) a substantial increase in anti-aging properties, and brightness, hue and saturation and other indicators were also improved to some extent, very earth broaden the quality and scope of application of organic pigments (dye) material. Ability silica reflection of UV, good stability, is not decomposed after UV irradiation, not color, it will not react with other components of the formulation. It can be applied in advanced cosmetic, UV plexiglass like new.
