| titleOfInvention | A kind of preparation method of composite silicon powder |
| abstract | A method for making composite silicon powder, comprising the following steps: S1. Select four materials of silica fume, quicklime, alumina and titanium dioxide; S2, after mixing, send it to a plasma electric furnace for high-temperature melting and mixing, and the melting temperature is 2600-2760 degrees Celsius; S3 the molten mixture is naturally cooled after being taken out, and sent to a crusher to be broken into coarse blocks with a particle size of 50-100 mm; the coarse blocks are subjected to coarse grinding and sieving to obtain coarse powder; the coarse powder is added with a grinding aid for ultra-fine processing to become fine powder; In S4, the micropowder is subjected to interface treatment in an environment of 110-120°C, and a small amount of reinforcing agent is added for micro-compounding, and the finished product is output after cooling and mixing by a cold mixer. By adopting the method for producing the composite silicon powder of the present invention, the obtained composite silicon powder has a bulk density of 0.9-1.5 g/cm3, a large particle size span, excellent microscopic gradation, good dispersion performance, and an obvious water requirement when mixed into concrete. It can effectively reduce the drying shrinkage rate of concrete. |
