Sodium metasilicate is a non-toxic, tasteless, pollution-free white crystalline granular, easy soluble in water, insoluble in alcohol or in acid. As a kind of important inorganic chemical product, it has a variety of uses in many fields and more and more uses will be developed in the future.
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.
