Application
1. One of the basic chemical raw materials, widely used, is an important raw material for glass, soap, detergent, textile, leather, spices, dyes, medicines, etc.
2. Used as an analytical reagent, also used in the pharmaceutical industry and photoengraving
3. Widely used in glass products, chemicals, paper, metallurgy, medicine, textile and food industries
4. Used in the food industry as a neutralizing agent and a leavening agent, such as amino acids, soy sauce and pasta such as taro and bread. It can also be added to the pasta with alkaline water to increase elasticity and ductility.
5. Used as a detergent in wool rinsing, bath salts and pharmaceuticals, alkaline agents in tanning.
6. Most of it is used in industry, and a small part is for civilian use. In industrial soda ash, it is mainly light industry, building materials, chemical industry, accounting for about 2/3: followed by metallurgy, textile, petroleum, national defense, medicine and other industries.
The glass industry is the large consumer department of soda ash, which consumes 2.Ot of soda ash per ton of glass.
The chemical industry is used for water glass, sodium dichromate, sodium nitrate, sodium fluoride, baking soda, borax, trisodium phosphate, and the like.
The metallurgical industry is used as a smelting flux, flotation agent for ore dressing, steelmaking and smelting as a desulfurizer. The printing and dyeing industry is used as a water softener.
The tanning industry is used for degreasing raw materials, neutralizing chrome tanned leather and increasing the alkalinity of chrome tantalum. Also used in the production of synthetic detergent additives sodium tripolyphosphate and other sodium phosphate salts.
7. As a buffer, neutralizer and dough improver, it can be used in pastry and pasta, and it can be used according to the production needs.
