The purpose and function of white carbon black, the function of different uses white carbon black
We know that white carbon black is silica that can replace black carbon black. We also know the simple uses and functions of white carbon black, but the role of white carbon black for specific uses is really unknown. Let me introduce the uses and functions of silica from multiple angles.


　　The use and function of fumed silica
Fumed white carbon black is also called nano white carbon black, which can be widely used in various industries as additives and catalyst carriers. Specifically, there are petrochemicals, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, and ink thickening. Agents, soft metal polishing agents, insulating fillers, high-grade daily cosmetics fillers and spray materials, medicine, environmental protection and other fields. It also provides a new material foundation and technical guarantee for the development of related industrial fields. Compared with conventional materials, it shows special functions in magnetic, catalytic, light absorption, thermal resistance and melting point, so it has received great attention.


　　Purpose and function of precipitated silica
　　 precipitation method silica is further divided into traditional precipitation method silica and special precipitation method silica. The former refers to white carbon black produced with sulfuric acid, hydrochloric acid, CO2 and water glass as basic raw materials, and the latter refers to the use of supergravity technology, sol-gel method, chemical crystal method, secondary crystallization method or reverse micellar micro White carbon black produced by special methods such as emulsion method. Precipitated silica is mainly used as a reinforcing agent for natural rubber and synthetic rubber, toothpaste friction agent, etc. White carbon black is a highly dispersed amorphous powder or flocculent powder, which is light in weight and has high electrical insulation, porosity and water absorption. Its original particle size is less than 3um, so it has a large surface area, good reinforcement and viscosity enhancement, and good dispersion, suspension and vibration liquefaction characteristics. It has been widely used in plastics, rubber, papermaking, coatings, dyes and inks, etc. Several areas, especially in the rubber industry.


　　The use and function of water-soluble silica
　　 Water-soluble silica is mainly used in water-based paints. Adding silica to water-based paints can not only prevent the precipitation of water-based paints, but also improve the absorption of pigments and dyes and improve dispersibility. When used as a filler in emulsified coatings, it can improve thermal stability.


　　 Use and function of hydrophobic silica
Hydrophobic white carbon black is the most suitable rheology in processing and use, thickening of polar liquids, such as epoxy resin; reinforcement of silicone elastomers, high addition, such as in molded products, good hydrophobicity, Improve anti-corrosion, improve dielectric properties, such as in cable composites, powder glidants, such as powder coatings and fire extinguishing agents, etc.; improve scratch resistance in coatings and plastics.



The use and function of white carbon black in construction mortar
　　 The application of white carbon black in construction mortar, such as the application of exterior wall mortar, can effectively improve the abrasion resistance of construction mortar, improve the surface finish of materials, and improve the anti-aging performance of construction materials.


　　The use and function of white carbon black in the ceramic industry
When white carbon black is added to the ceramic industry, it can not only play the role of nano particles, but also the second phase particles, which not only improves the strength and toughness of the ceramic material, but also improves the hardness and elastic modulus of the material. . The use of white carbon black to composite the ceramic substrate not only improves the density, toughness and smoothness of the substrate, but also greatly reduces the sintering temperature. In addition, the application effect of fumed silica in ceramic products such as ceramic filters and corundum balls is also very significant.


　　The use and function of resin and white carbon black
　　The addition of white carbon black to the resin composite material can effectively increase the strength, elongation, wear resistance, and improve the surface finish and anti-aging properties of the material.


　　The use and function of white carbon black on rubber
　　 After adding a small amount of fumed silica to ordinary rubber, the strength, abrasion resistance and aging resistance of the product reach or exceed high-end rubber products, and the color can be kept unchanged for a long time. It can be seen that the use and function of white carbon black rubber are also good.


　　The use and function of diatom peat white carbon black
The diatom mud is mainly expressed in the form of texture, and the white carbon black is embodied in the form of wallpaper flowers; the white carbon black decorative wall material is much more complicated than the diatom mud, and the addition of white carbon black to the diatom mud can effectively give the diatom Mud tree shape, and increase the diatom mud product formaldehyde evolution rate, moisture absorption and release, anti-mold and other properties.


　　The use and function of white carbon black in plastics
The use of fumed silica for light transmission and small particle size can make the plastic more compact. The addition of fumed silica to the polystyrene plastic film will not only improve its transparency, strength, and toughness, but also waterproof and anti-aging properties. Significantly improved.


　　 Use and function of white carbon black in feed carrier
　　 White carbon black is treated with low impurities and has a high specific surface area. It can be used as a carrier in industries such as feed additives, pesticides, and washing powder to increase its fluidity; and can be used for coloring in ceramic glazes. Feed grade silica is used as an anticaking agent, adsorbent or as a carrier for choline, copper sulfate, and premix in the feed industry.


　　The use and function of white carbon black in coatings
　　1. The use and function of white carbon black in water-based coatings
　　The addition of white carbon black to the water-based paint can not only prevent the precipitation of the water-based paint, but also improve the adsorption of pigments and dyes and improve the dispersibility. When used as a filler in emulsified coatings, it can improve thermal stability.


　　2. The use and function of white carbon black in powder coatings
　　 White carbon black is an important part of powder coatings, which can give the coating a brilliant and colorful color, improve the mechanical and chemical properties of the coating, or reduce the cost of the coating. White carbon black is mostly used as a loose flow agent in powder coatings to prevent agglomeration and improve spraying efficiency. There are also auxiliary purposes for extinction and sand texture.


The above are the uses and functions of white carbon black. Of course, white carbon black not only has the above uses, but also can be used in concrete, molds, aquatic products, agricultural chemicals, daily chemical products, paper fillers, fire fighting agents, and cosmetics. , Matting agents, pigments, paints, electronic packaging materials, ceramics, sealants, adhesives, glass steel products, drug carriers, antibacterial materials and other products have a certain effect.
