Valve mouth bag rubber shoes and other rubber products
White carbon black with high whiteness, fine particles, the use of white carbon black vulcanized rubber transparency is high, but also can improve the comprehensive physical properties of rubber material. Therefore, as the main reinforcing filler, white carbon black is widely used in the production of rubber shoes, especially in transparent and translucent sole rubber materials. At present, Qingdao area most of the Korean capital shoemaking enterprises are using high transparency and clear carbon black.
In the production of adhesive tape, in order to improve its wear resistance, a large amount of white carbon black is added. At the same time, the silanol on the surface of white carbon black plays a role in improving the wettability of adhesive material and fabric, which is conducive to the diffusion and infiltration of adhesive material.
In addition to the above products, white carbon black is also used for rubber roller, rubber hose, rubber plate, wire and cable and household appliances, stationery rubber parts and so on.
Silicone rubber
Silicone rubber has high heat resistance and excellent cold resistance, ozone resistance, aging resistance and atmospheric aging resistance, and has excellent electrical insulation. It can be used in the range of -60℃-250℃ for a long time, and with the change of temperature, strength and other physical indicators change little. In addition, silicon rubber has low water absorption and can be stored in wet places for a long time with moisture content ≤0.015%. Because of the above characteristics of silicone rubber, it is widely used in aerospace, electronic industry and instrument and instrument industries. But the application of silicone rubber began with the emergence of silica, especially gas phase silica whose price is too high. Began to use precipitated silica instead of gas phase silica, but now the domestic precipitated silica can only be used in the use of low-grade silicone rubber.
The pharmaceutical industry
White carbon black has physiological inertia, high absorbability, dispersity and thickening, and has been widely used in pharmaceutical preparations. For example, a large number of pseudo-biogenic E powder now uses white carbon black as a carrier.
Pesticide industry
The main role of white carbon black in the pesticide industry is as a carrier, improve liquidity and prevent caking, at present, white carbon black is mainly used in all kinds of wettable powder.
Application in ink
White carbon black in ink mainly thickens, used to control the flow of printing ink. Also used to control the flow of printer ink, so that it can not be arbitrary flow or flow hanging, in order to obtain a clear print.
Paints and coatings of the matting agent
Silica is widely used in water-based and solvent-based transparent wood coatings (wood varnish), high solid points of coatings, architectural coatings, wallpaper coatings and so on as the extinction agent, with polymer wax treatment of silica extinction agent deputy county long in water-based transparent wood coatings, the film has excellent optical properties, only soft precipitation in use.
Because of the many functions of white carbon black products, it has become an indispensable additive for many industrial sectors, especially for the production of small environmental pollution, with broad prospects for development.
