Sodium carbonate is one of the important
chemical raw materials. It is widely used in light
industry, daily chemicals, building materials, chemical
industry, food industry, metallurgy, textile,
petroleum, national defense, medicine and other fields.
It is used as a raw material, cleaning agent,
Detergents are also used in the fields of photography
and analysis. Followed by metallurgy, textiles,
petroleum, national defense, medicine and other
industries. The glass industry is the largest consumer
of soda ash, which consumes 0.2 tons of soda ash per
ton of glass. In industrial soda ash, mainly light
industry, building materials, chemical industry,
accounting for about 2/3: followed by metallurgy,
textile, petroleum, national defense, medicine and
other industries.
1. The
glass industry is a major consumer of soda
ash, which consumes 0.2t of soda ash per ton of
glass. Mainly used for float glass, kinescope glass
bulb, optical glass, etc. 2. It can also be used in
other sectors such as chemical industry and
metallurgy. The use of heavy soda ash can reduce soda
dust flying, reduce raw material consumption, improve
working conditions, and improve product quality. At
the same time, it can reduce the corrosion effect of
alkali powder on refractory materials and extend the
service life of the kiln. 3. As a buffer, neutralizer
and dough improver, it can be used in cakes and pasta
foods, and used in appropriate amounts according to
production needs. 4. As detergent for wool rinsing,
bath salt and medicine, alkali agent in leather
tanning. 5. Used in the food industry as a
neutralizer and leavening agent, such as the
manufacture of amino acids, soy sauce and pasta foods
such as steamed bread and bread. It can also be mixed
with alkaline water and added to pasta to increase
elasticity and ductility. Sodium carbonate can also
be used to produce MSG 6. Used in the pharmaceutical
industry as an antacid and osmotic laxative. 7.
Anhydrous sodium carbonate is used for chemical and
electrochemical degreasing, electroless copper
plating, aluminum corrosion, electrolytic polishing
of aluminum and alloys, chemical oxidation of
aluminum, sealing after phosphating, rust prevention
between processes, electrolytic degradation In
addition to chromium plating and chromium oxide film
removal, it is also used in pre-plating copper, steel
plating, steel alloy plating electrolyte 8. In
metallurgical industry, it is used as smelting flux
and flotation agent for beneficiation, and as
desulfurization agent in steelmaking and antimony
smelting. 9. Used as water softener in printing and
dyeing industry. 10. In the tanning industry, it is
used for degreasing raw hides, neutralizing chrome
tanned leather and improving the alkalinity of chrome
tanning liquor. 11. The benchmark for calibrating
acid in quantitative analysis. Determination of
aluminum, sulfur, copper, lead and zinc. Test urine
and whole blood glucose. Analyze the co-solvent of
silica in cement. Metallographic analysis,
etc.
