Industrial ammonium chloride is a vital chemical raw material widely used in the production of refrigerants, dyes, rubber, and other industrial products. According to Chinese standards (GB/T2946-2008), industrial ammonium chloride is classified as follows: Qualified Grade: Ammonium chloride content: 99.0%; First Grade: Ammonium chloride content: 99.3%; Premium Grade: Ammonium chloride content: 99.5%.

Industrial ammonium chloride serves as a degreaser and etchant for metal surface treatment, dissolving oils, oxide layers, and metallic impurities. It finds extensive application in processes such as electroplating, spraying, and welding. It also functions as a solvent for aluminum surface treatment, removing surface oxides, cleaning surfaces, and enhancing adhesion to other metals.

Additionally, industrial ammonium chloride serves as a cleaning and degreasing agent for glass and ceramics, adsorbing contaminants and oxides from their surfaces while maintaining surface smoothness and transparency. It is also used in the production of ammonium chloride desiccants, ammonium salts, and other chemicals.

Finally, in industrial production settings such as thermal power plants and steel mills, industrial ammonium chloride aids in removing nitrogen oxides from flue gas emissions, thereby reducing air pollutant discharges.
