It has the strong capability of cleaning, widely used for the manufacture of a variety of detergents in detergent industry, so it is the best substitute for STPP, reducing environmental pollution.2. Sodium meta silicate provides anti-corrosion protection to metals (zinc, aluminum, etc.) and is used as metal cleaner and metal surface treatment agents.3. In the textile industry: mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.4. In the Paper & Printing Industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.5. In the ceramic industry: used for sludge thinners. It is especially suitable for additives used in slip-casting forming and ceramic forming.6. In the metallurgical industry: used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, and foundry and separating agents.7. In the construction field: used for concrete dispersion agent and hardening accelerator. It is also used as coagulation accelerator.Sodium metasilicate nonahydrate Na2SiO3 9H2OITEMTesting resultSodium oxide(Na2O)%20.0-22.0Silica(SiO2)%19.0-22.0Water insoluble%≤0.30Iron(Fe)%≤0.05Whiteness≥70Sodium metasilicate Pentahydrate Na2SiO3 5H2OITEMNATIonAL QUALITY INDEXSodium oxide(Na2O)%28.50_30.00Silica(SiO2)%27.30_29.20Water insoluble%≤0.2Iron(Fe)%≤0.03Whiteness≥75PH(1%SOLUTION)12.5±1.0%Sodium metasilicate Anhydrous Na2SiO3 ITEMTesting resultSodium oxide(Na2O)%50.0-52.0Silica(SiO2)%≥45.0Water insoluble%≤0.25Iron(Fe)%≤0.03Whiteness≥75
