sodium metasilicate anhydrous/pentahydrate

Product Description

Sodium metasilicate is an inorganic white granule or powder, non-toxic, tasteless and environmentaly-safe. It is strongly alkaline, having strong capacity of cleaning, buffering and softening, counteracting acidic contamination, emulsifying fat and oil, deflocculating to inorganic. It can replace STPP to be used for the manufacture of effective detergents and rust remover for metal, reducing environmental pollution, preventing corrosion for metal (zinc, aluminum, etc.). Scope of Applications 1. Widely used for manufacturing of a variety of detergents 2. Rust remover for metal 3. Grinding aids for ceramics 4. Deinking agent for paper 5. Dyeing and printing auxiliary for removing oil in textile industry 6. Used in water reducing agents, sodium metasilicate pentahydrate is able to integrate more hydrones to make better moisture absorption effect. 7. Raw material for flameproofing agent Na2SiO3 (granular) quality standards(HG/T******4) ITEM NATIONAL QUALITY INDEX TESTING RESULT Sodium oxide(Na2O)% *0.*0�1.*0 *1.*4 Silica(SiO2)% *6.*0�1.*0 *6.*3 Iron(Fe)% ≤**0ppm *7 Bulk density(g/cm3) 1.***1.*5 1.*3 Particular Size(****5mesh)% ≥*3.0 *9.*6 Whiteness ≥*5 *0.*4
