Water softener used as boiler water and industrial water (including water for dye production, water for titanium dioxide production, water for printing and dyeing, water for cleaning color film copies, chemical water, reagent production water, etc.) and water treatment agent for industrial circulating cooling water; It is also used as corrosion inhibitor, flotation agent, dispersant, high temperature binder, dyeing assistant, metal surface treatment, rust inhibitor, detergent assistant and cement hardening accelerator. Coated paper production is used as a slurry dispersant to improve permeability. In addition, it is also used in washing utensils and chemical fibers to remove iron ions from pulp. In the petroleum industry, it is used for rust prevention and control of drilling pipe and adjusting the viscosity of mud during oil drilling.

It is mainly used as water softener for boiler, water softener for printing and dyeing bath and paper diffusion agent. It is also used as corrosion inhibitor, flotation agent, dispersant and high temperature binder. Others are used in washing utensils and chemical fibers to remove iron from pulp. It is also used for soil analysis.
