White carbon black, gas phase white carbon black, gas phase silica.

the original title: White carbon black, gas phase white carbon blackgas phase silicon dioxidewhite carbon black is the white powdery X-ray amorphous silicone and silicate products, mainly refers to the precipitation of silica, gas-phase silica, ultra-fine silicone gel and gas gel, including powder-like synthetic alumina silicate and calcium. White carbon black is a porous substance, composed of SiO2.nH2O, wheren H2O is present in the form of surface hydroxyl. Soluble in caustic acid and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature, non-combustible, odorless, odorless, with good electrical insulation.ingredients white carbon black according to the production method is generally divided into precipitation method white carbon black and gas phase method white carbon black. The gas-phase method white carbon black normal is white amorphous translucent solid gel-like nanoparticles (particle size less than 100nm), non-toxic, there is a huge surface area. Gas phase method white carbon black is all nano-silicon dioxide, product purity can reach 99%, particle size can reach 10 to 20 nm, but the preparation process is complex, expensive; The former refers to silicon dioxide produced by sulfuric acid, hydrochloric acid, CO2 and water glass as the basic raw materials, while the latter refers to silicon dioxide produced by special methods such as superstrength technology, sol-gel method, chemical crystal method, secondary crystallization method or inverting gel beam microemulsation method. Precipitated white carbon black is mainly used as a reinforcement of natural rubber and synthetic rubber, toothpaste friction agent and so on. Gas-white carbon black is mainly used as silicone rubber reinforcement, coating and unsaturated resin thickener, ultra-fine silicondioxiy gel and aerogel are mainly used as coating extinction agent, thickener, plastic film opener and so on.usebecause of a series of advantages of white carbon black products, so that it can be widely used in many fields.1, rubber products white carbon black used in color rubber products to replace carbon black to strengthen, to meet the needs of white or translucent products. White carbon black also has a strong adhesion, tear resistance and heat resistance to aging performance, so in black rubber products can also replace part of carbon black, in order to obtain high-quality rubber products, such as off-road tires, engineering wheel tires, meridian tires and so on.2, agricultural chemicalsin agricultural chemicals, such as pesticides, high-efficiency fertilizer, the use of white carbon black as a carrier or thinner, can maintain long-lasting effect, because it has a high adsorption, easy suspension, has good affinity and chemical stability, even in rain, flushing and hot conditions, can remain unchanged for a long time.3, daily chemical productswith white carbon black as fillers and abrasive transparent color and opaque toothpaste, this kind of toothpaste has good flexibility, dispersion, cream smooth, soft, abrasive good, do not abrasive toothpaste tube body; In particular, with nitride has a good mating, can avoid calcium salt as abrasive produce insoluble salt disadvantages.4, the gelused in natural rubber or synthetic rubber made of adhesive, provides touch degeneration and reinforcement, at the same time because of its stretch can also improve the adhesion, high price and low price.5, anti-clumping agentwhite carbon black can be used in a number of products to improve free mobility, such as grassland fertilizer, fungicides, grinding wheel abrasives, laundry bleach, phenolinjection ullotopin, phenolic and urea plastic products, the manufacture of rubber sulfur and anti-clump mixture.6, paper filler paper filler with white carbon black paper filler can improve the paper ink through performance and mechanical strength, increase the degree of whiteness, reduce unit weight. It can effectively achieve paper lightweight, reduce production costs, improve the performance of paper use.can also be used in fire protection agents, feed, cosmetics, extinction agents, pigments, paints and many other industries.
