When sodium carbonate is hydrolyzed in aqueous solution, the ionized carbonate ions combine with hydrogen ions in water to form bicarbonate ions, resulting in the reduction of hydrogen ions in the solution and the remaining ionized hydroxide ions. Therefore, the pH of the solution is alkaline, so it is called soda ash. There are many sodium carbonate manufacturers in Weifang. Let’s go into the following to learn about them Soda ash has weak irritation and corrosion. Direct contact can cause skin and eye burns. Inhalation of dust and smoke can cause respiratory tract irritation and conjunctivitis, as well as nasal mucosa ulcer, atrophy and perforation of nasal septum. Eczema, dermatitis, cornlike ulcer and skin relaxation may occur after long-term contact with the solution. The incidence rate of respiratory diseases increased with the exposure of workers exposed to the product. It can cause digestive tract burn, mucosal erosion, bleeding and shock. 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 and other fields. It is used as raw material, cleaning agent and detergent for manufacturing other chemicals. It is also used in photography and analysis fields. Glass industry is the consumption Department of soda ash, which consumes 0.2 tons of soda ash per ton of glass. Mainly used for float glass, kinescope glass shell, optical glass, etc. Soda ash is also used to make refractories and glazes in ceramic industry. It is used in food industry as neutralizer and leavening agent, such as making amino acids, soy sauce and flour products, such as steamed bread and bread. It can also be added into pasta to increase elasticity and ductility. Sodium carbonate can also be used to produce monosodium glutamate. Anhydrous sodium carbonate is used for chemical and electrochemical degreasing, electroless copper plating, etching of aluminum, Electropolishing of aluminum and alloy, chemical oxidation of aluminum, sealing after phosphating, rust prevention between processes, electrolytic stripping of chromium coating and oxide film, etc. it is also used in electrolyte of pre copper plating, steel plating and steel alloy plating.
