use

1. It is widely used in the purification of industrial water and tap water, which can reduce the hardness of water and accelerate the sedimentation of suspended solids.

2. It is used as a thickener for oil production acidification fracturing fluid, a crosslinking agent for water shutoff and profile control, and it is used in conjunction with polymers. And used as neutral paper sizing agent, soil hardening agent, cement admixture and catalyst.

3. It is used as an inhibitor of alkali washing solution for glass and ceramic etching. It is used as a filler in the paper industry to reduce the viscosity of oil well water and as a protective agent for steel surface treatment. It is also used as a soil hardener and used in soap, dye and other industries.
