| Abstract: | Water glass and sulfric acid are used as raw material. Silica sol is first made as mother liquor, then the synthetic reaction at pH 9.0 -10.5 is carried out.The slurry of precipitated silica is treated by acidification,filtration,washing,drying and comminuting,the finished product is finally obtained. The process is simple and easy controlled , the product presents excellent performance in rubber reinforcing. |
