SODIUM METASILICATE PENTAHYDRATE also named Pentahydrate Sodium Metasilicate. MOLECULAR FORMULA: Na2SiO3• 5H2O APPEARANCE: White granular CHARACTERISTIC: Crystalloid, bulk density: 0.8-1.0g/cm3, it's easily dissolved in water or attenuant lye but it's difficult to dissolved in ethanol and acid and its solution is slightly alkaline. It is ealily to absorb moisture when it is stocked in the open air. It has charaters of absterged, decentralization, wetness, penetrability, and pH value buring. USAGE: Sodium metasilicate pentahydrate was mainly used in making high efficiency detergent, metal cleaner, pottery grinding aid, fire retarding agent, water retention agent, degreasing agent, textile agent and paper deinking agent. BRIF INTRODUCTION: QDSS is one of main drafter of indrustry standard for sodium metasilicate. Our sodium metasilciate anhydrous was approved as FAMOUS BRAND OF QINGDAO. The equipment, production line and technology were first independently designed by QDSS in the same industry. QDSS also is the earlier manufacturer of sodium metasilicate pentahydrate and nonahydrate. QDSS also won much of reputation form mainland (China) and other foreign countries from 2001.
