APPLICATION

Agricultural use

Sodium chloride can be used to improve saline alkali land by increasing the salt content of the soil to inhibit the growth of certain pests and pathogens.

sodium chloride

Sodium chloride is commonly used as a snow melting agent in winter, sprinkled on roads to accelerate the melting of snow, reduce icing, and ensure traffic safety.

water treatment

In the water treatment process, sodium chloride can be used to regulate the hardness of water and remove calcium and magnesium ions through ion exchange.
