The core use of industrial salt
1, Chemical production
Basic chemical raw materials
Manufacturing basic chemicals such as hydrochloric acid, caustic soda, soda ash, chlorine gas, ammonium chloride, etc;
As raw materials for the production of inorganic salts (such as sodium carbonate, calcium chloride, sodium sulfate, etc.).
Organic synthesis and process assistance
Production of sodium sulfide, insurance powder and other products used in the dye industry;
As a catalyst or additive, participate in the production processes of rubber, soap, pesticides, etc.
2, Metallurgy and Machinery Manufacturing
Metal processing
Used as a desulfurizer, quencher, and melting aid in metallurgy to lower the melting point of metals and improve purity;
Key materials for metal surface treatment (such as steel pickling, electroplating pretreatment).
Casting and Machining
As a casting binder, it prevents cracking of the casting core at high temperatures;
The heat treatment medium in a salt bath furnace is used to uniformly heat metal workpieces.
3, Architecture and Building Materials
Glass manufacturing: Soda ash (produced from salt) is the main raw material for glass, and salt is directly used as a clarifying agent to enhance transparency;
Ceramics and cement: used for ceramic glaze, cement additives, adjusting setting time and body strength.
4, Water Treatment and Environmental Protection
Hard water softening: removing calcium and magnesium ions through ion exchange resin regeneration;
Wastewater treatment: used as a flocculant or regulator to purify industrial wastewater;
Swimming pool disinfection: Electrolyze saltwater to generate chlorine gas for water disinfection.
5, Energy and Mining Industry
Petroleum and natural gas: preparing drilling fluid to adjust density and viscosity, used for oil and gas well completion operations;
Refrigeration and energy storage: Salt solutions are used as refrigerants or cooling media for refrigeration equipment.
6, Other fields
Food processing (non direct consumption)
Preservatives for pickled foods (such as cured meat and sauces) and processing aids (subject to strict supervision).
Roads and Agriculture
Winter road de icing and snow melting (lowering freezing point);
Prepare soil conditioners or specific fertilizers in agriculture.
