Silica and carbon black are two excellent chemical raw materials widely used in many industries. We are very familiar with their characteristics and application fields, but I think familiarity is familiar, but have you studied their differences in detail? Can carbon black replace part of the function of carbon black?
The difference between carbon black and white carbon black processing raw materials
Carbon black is a fine powder produced by incomplete combustion of carbon-containing raw materials, while white carbon black is a high-resistance rubber and plastic product additive made of sericite as the main raw material and other ingredients through fine processing.
The difference between carbon black and white carbon black
Carbon black is a black powdery substance formed by incomplete gas phase combustion or pyrolysis of hydrocarbons under strictly controlled process conditions, and its main component is carbon.
White carbon black is the general term for white powdery X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica, ultrafine silica gel and aerogel, including powdered Synthetic aluminum silicate and calcium silicate, etc., its composition can be represented by SiO2 nH2O, where nH2O exists in the form of surface hydroxyl groups.
The difference between carbon black and white carbon black
Carbon black is generally black, while silica is white.
The difference between the application of carbon black and white carbon black
Carbon black is a black pigment and also the cheapest pigment. It has strong tinting power and hiding power, and does not irritate the eyes. It is stable, heat-resistant, chemical-resistant, and light-resistant.
Silica has high temperature resistance, non-combustibility, tasteless, odorless, and has good electrical insulation.
Can white carbon black replace carbon black?
Carbon black and silica are completely two substances, but they can be substituted in some respects. For example, in order to meet the needs of white or translucent products, silica can replace carbon black for reinforcement.
