| titleOfInvention | Method for preparing white carbon black and high modulus water glass at the same time from metallic silicon powder and white carbon black |
| abstract | The invention relates to a method for simultaneously preparing white carbon black and high modulus water glass from metal silicon powder and the white carbon black. The metal silicon powder is subjected to a hydrolysis reaction in an alkaline aqueous solution, and the reaction product is composed of a precipitate and a solution product; Pickling, washing with water, drying and pulverizing are to obtain white carbon black; the mass content of silica in the white carbon black is ≥90%; the solution product is high modulus water glass, the modulus of which is higher than 3.5. Compared with the industrial production method of precipitation white carbon black, the method of the present invention not only has a short process and is convenient to operate, but also does not need to use a large amount of acid, and does not generate a large amount of salt-containing waste water, which can reduce environmental pollution and reduce carbon emissions. The product white carbon black can be widely used in rubber, papermaking, toothpaste, etc. In addition, the present invention simultaneously produces high modulus water glass, and also has a wide range of uses, such as as a binder, production of silica sol, etc., compared with ordinary molds. Several water glass has a higher market value. |
