Application
Soda ash has a number of diversified uses that touch our lives everyday. Glass manufacturing is the largest application for soda ash whether it is in the production of lat glass, containers, fiberglass insulation for the housing, commercial building, and automotive industries. Soda ash is also used to clean air and waste water.

1) Glass Industries

The main use of soda ash dense is for glass industries, flat glass and container glass, etc. In glass industries, soda ash function as a fluxing agent in lowering the melting point of other glass ingredients, and also soda ash is a relatively inexpensive source of sodium oxide(Na2O) for soda –lime glass.

2) Sodium Chemicals

Soda ash provides the sodium source for the manufacture of many sodium salts including sodium phosphates, sodium sulfate, sodium sulfite, sodium acetate, sodium nitrite, sodium silicate, etc.

3) Soap and Detergent
Soda ash is used for soap manufacturing as neutralizing agent. Also soda ash is the raw material of laundry soap as a builder, which strengthen the washing ability in detergent. Soda ash is the main component in synthetic detergent. Soda ash is used for manufacturing sodium per carbonate, which is one of famous bleaching agent.

4)Mineral refining
Soda ash is proven that it’s very useful to refine the minerals for producing steel products. Soda ash is acted as catalytic agent to remove sulfur and phosphorous in steel smelting process.

5)Food Industries
As one of food additives, soda ash is used for manufacturing mono sodium L-glutamate and soybean

textile industry, glass making industry, detergent industry, etc
