щелочной обезжириватель гранулированный

Sodium metasilicate pentahydrate 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 Physical Appearance: White granules or powder solid Odor : Odorless PH: 12.4 at 1wt/wt% Specific Soubility : Soluble 61 wt/wt% at 30 C (86F) Melting Point Range : 72 C (162F) Molecular Weight : 212.14 UN Hazard Class/division 8 CAS Registry No. 10213-79-3 UN No. 3252 Na2SiO3 5H2O (granular) quality standards (HG/T2568-94) ITEM NATIONAL QUALITY INDEX TESTING RESULT Sodium oxide(Na2O)% 28.00-30.00 29.10 Silica(SiO2)% 27.00-29.00 28.87 Water insoluble% ≤0.2 0.055 Iron(Fe)% ≤0.03 0.005 Whiteness ≥75 86 Particular Size (16-30mesh)% ≥90 98 PH(1%SOLUTION) 12.5±1.0% 12.6
