Product details
Sodium Metasilicate Pentahydrate
 

Item
 
Sodium Metasilicate Pentahydrate
Product Description
MF: Na2SiO3.5H2O
Purity: SiO2 27%~29%
Appearance: White crystal or powder
 
Features
Sodium metasilicate pentahydrate is strongly alkaline, having strong capacity of cleaning, buffering and softening, counteracting 
acidic contamination, emulsifying fat and oil, deflocculating to inorganic.
 
Application
1. 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.
