Main use industry

Sodium hexametaphosphate and sodium fluoride heating manufacturing fluorine sodium phosphate, the latter as the important industrial raw material;

 sodium hexametaphosphate as a water softener, such as used in dyeing and finishing, water softening effect;

Sodium hexametaphosphate also as scale inhibitor is widely used in EDI electrodialysis (resin), RO (reverse osmosis), NF (NF), and other water treatment industry.

Used in boiler water and industrial water (including the dye production water, titanium white production water, printing and dyeing mixing and dyeing water. Color film copy water cleaning, water and chemical, pharmaceuticals, reagent production water softener, etc.), industrial circulating cooling water of water treatment agent;

Also used as a corrosion inhibitor, flotation agent, dispersing agent, high temperature binder, dyeing auxiliaries, metal surface treatment, corrosion inhibitor, detergent additives, cement hardening accelerator.

Coated paper production as a slurry dispersant, in order to improve the penetration. In addition is also used to wash dishes and chemical fiber for the removal of iron ions in the pulp.

For drill pipe in the oil industry of rust prevention and control oil drilling mud viscosity.

Mainly used in boiler water softener, printing and dyeing, dye bath water softener and paper diffusion agent.

Also used for corrosion inhibitor, flotation agent, dispersing agent and high temperature binder.

Used for washing utensils and other chemical fiber is used to remove the iron in the pulp.

Also used for soil analysis

     preparation

 sodium dihydrogen phosphate method Sodium dihydrogen phosphate by water heating to 110 ~ 230 ° C, respectively, to take off two crystal water and water structure, further heating to 620 ° C and dewatering, the melt being generated, and aggregated into sodium hexametaphosphate. Cool and then discharged from 650 ° C to 60 ~ 80 ° C producer, after crushing sodium hexametaphosphate was finished, the phosphorus pentoxide mixed with soda ash according to certain proportion, and heating the take off together, sodium hexametaphosphate melt generated by quenching production, cooling, industrial sodium hexametaphosphate finished products.
