The difference and relationship between white carbon black and carbon black, the chemical formula is different but the product name is similar


Although there is only one word difference between white carbon black and carbon black, the two are completely different substances. Then the names of these two different substances are only one word apart, which has to be reminiscent of the relationship between them. Xinyuan Pigment Carbon Black analyzes the difference and relationship between white carbon black and carbon black as follows:
　　The difference between white carbon black and carbon black
　　 1. Silica and carbon black have different chemical formulas
　　 white carbon black chemical formula: SiO2.nH2O, chemical name: hydrated silica, product name: white carbon black. The main component of carbon black is elemental carbon, and contains a small amount of oxygen, hydrogen and sulfur. The chemical formula of the main component: C, the product name: carbon black.
　　2. The production process of white carbon black and carbon black is different
　　 The main production processes of white carbon black are combustion method (that is, gas phase method or dry method) and precipitation method (wet method). The combustion method uses silicon halide (such as silicon tetrachloride SiCl4) as a raw material, and hydrolyzes it in a hydrogen-oxygen stream at high temperature to obtain extremely fine hydrated silica (SiO2*nH2O). In the precipitation method, soluble silicate is decomposed with acid to produce hydrated silica.
The main production processes of carbon black are furnace method, spray method, lamp smoke method, groove method, drum method, mixed gas method, thermal cracking method, acetylene method and plasma method, among which furnace method, spray method, lamp smoke method, The groove method, drum method, and gas mixing method are incomplete combustion methods, and the thermal cracking method, acetylene method and plasma method are thermal cracking methods.
　　 3. There is a difference between white carbon black and carbon black
　　 white carbon black has the characteristics of being easily crushed, and is mainly used for oily matter absorption and dispersing agents, such as pesticide carriers. At the same time, white carbon black is also widely used as a matting agent in paint, coating, rubber and other industries.
　　 Carbon black is an important raw material in the rubber industry. Without carbon black, there would be no rubber industry today. At the same time, carbon black can also be used in the coloring of ink coating plastics.



The relationship between white carbon black and carbon black
　　 Although there are many differences between white carbon black and carbon black, in the common field of white carbon black and carbon black, white carbon black and carbon black can be replaced with each other, of course, taking into account the different colors.
　　The main relationship between white carbon black and carbon black is that white carbon black can completely replace carbon black for reinforcement when used in colored rubber products to meet the needs of white or translucent products. The complete replacement here is that there is no need to change the production process, as long as the relative indicators are the same, they can replace each other.
