Gas phase white carbon black is a kind of amorphous silica powder obtained by the combustion of silicon tetrachloride and methyl silicon trioxide in oxygen and hydrogen flame. The particle size of the powder can reach the nanometer level, which is a commonly used nano inorganic material.
Gas phase white carbon black original particle size between 7 ~ 80nm, the specific surface area is generally greater than 100㎡/g, with nano effect, in the material shows a variety of excellent performance, mainly as an additive, filler used, a wide range of uses, can make the matrix material to increase many properties do not have itself.
Filling reinforcing effect: adding gaseous silica to the matrix material can improve the tensile strength, modulus and other mechanical properties of the material. Flame retardant and smoke suppression: the use of gaseous silica and flame retardant helps to improve the flame retardant effect of the material and reduce the amount of smoke during combustion. Effect of increasing flow: gaseous silica can enhance the fluidity of dispersed particles in the dispersion system and prevent consolidation and settlement of particles. Thickening effect: adding gas phase white carbon black to paint and ink can make the coating to achieve the ideal viscosity. Decolorization effect: similar to carbon black, high surface energy for gaseous white carbon black provides a strong adsorption effect, can absorb colored impurities in the liquid. Catalyst carrier: gaseous silica can be evenly dispersed in solvent and matrix. Using gaseous silica as a carrier to carry catalyst into the system is helpful to improve the activity and efficiency of catalyst. Extinguishing effect: light refracts through the phase interface between gaseous silica and the matrix material, reducing the reflective effect of the material. Defoaming effect: adding gaseous silica in the fluid can reduce the generation of bubbles. Polishing agent: gas phase white carbon black hard, small particle size, similar to the grindstone, can be used as material surface grinding and polishing. In addition, there are many different uses of gaseous silica, used in medicine, research, chemical industry, daily use, cosmetics and other fields. According to Global Market Insight, the global gaseous silica market is estimated to be worth $1.59 billion in 2020 and is expected to exceed $2.3 billion by 2026, with a CAGR of 5.4% from 2021 to 2027.
