What's the difference between white carbon black and carbon black?
White carbon black should be familiar to all of you. Now it is very popular. There is another one called carbon black.Although it is only one word different, they are not the same. Today, we shall tell you about the difference between white carbon black and carbon black and whether they can be replaced.
In fact, white carbon black and carbon black are two substances. Some aspects can be replaced. Carbon black is a kind of black powder formed by incomplete combustion or pyrolysis of hydrocarbon in gas phase under strictly controlled process conditions. White carbon black is a general term for white powder X- ray amorphous silica and silicate products. It mainly refers to precipitated silica, fumed silica, ultrafine silica gel and aerogel, including powdered synthetic aluminum silicate and calcium silicate. Silica is a porous material, its composition can be expressed as SiO2 · nH2O, in which nH2O is in the form of surface hydroxyl. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non combustible, tasteless, odorless, with good electrical insulation. White carbon black is used in color rubber products to replace carbon black for reinforcement, to meet the needs of white or translucent products. White carbon black has strong adhesion, tear resistance, heat resistance and aging resistance at the same time, so it can also replace some carbon black in black rubber products to obtain high quality rubber products, such as off-road tires, engineering tires, meridian tyres and so on.
