| Abstract: | The preparation of sodium metasilicate pentahydrate from the dilute lye of zirconium oxychloride production is introduced.After removing the impurifies from the dilute lye and adding the supplementary water glass,the finished product sodium metasilicate pentahydrate is obtained through evaperating,crytallizating,separating and drying.The quality of the product can meet the superior grade of standard HG/T 2568-94,the manufature cost can decrease by 25%,compared to the conventional process.This technology is not only avoid the pollution caused by the discharge of dilute lye,but also a good economic and social benefit. |
