Description:
SODIUM METASILICATE PENTAHYDRATE also named Pentahydrate Sodium Metasilicate.
MOLECULAR FORMULA: Na2SiO3·5H2O
USAGE: sodium metasilicate pentahydrate was mainly used in making high efficiency detergent, metal cleaner, pottery grinding aid, fire retarding agent, water retention agent, degreasing agent, textile agent and paper deinking agent.
SODIUM METASILICATE ANHYDROUS, also named Anhydrous Sodium Metasilicate.
MOLECULAR FORMULA: Na2SiO3
APPEARANCE: beaded sodium metasilicate anhydrous is white beads, powdered sodium metasilicate anhydrous is white powder.
USAGE: sodium metasilicate anhydrous was mainly used in making high efficiency detergent, metal cleaner, pottery grinding aid, fire retarding agent, water retention agent, degreasing agent, textile agent and paper deinking agent. It is also widely utilized in oil-exploitation, nature gas exploitation, tunnel.
Applications:
In wash industry: 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 metasilicate provides anti-corrosion protection to metals (zinc, aluminium, etc.) and is used as metal cleaner and metal surface treatment agents.
In the textile industry: mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.
In the Paper & Printing Industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.
In the ceramic industry: used for sludge thinners. It is especially suitable for additives used in slip-casting forming and ceramic forming
In the metallurgical industry: used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, foundry and separating agents.
In construction field:used for concrete dispersion agent and hardening accelerator. It is also used as coagulation accelerator.
