Used for soft agent, detergent, antiseptic, cement presses hard agent, fiber and dyeing detergent, medicine, food, printing and dyeing, tanning, papermaking, etc For power station, locomotives, boiler and fertilizer plant cooling water processing agent, washing auxiliaries, control of anti-corrosion potions, cement hardened accelerator, streptomycin purification agent, fiber industry, bleaching and industrial cleaning agent. In petroleum industry, used for drilling pipe anti-rust and control of oil drilling rose when adjusting the viscosity of pulp . It is also used in fabric dyeing, tanning, papermaking, color film, soil analysis, radioactive chemistry, analytical chemistry industry. Sodium hexametaphosphate is made by soda or caustic soda solution and phosphoric acid on neutralization reaction , and continue to be heated by 250âÂÂÂÂ.It generates partial sodium, then heated to 620â melting and polymerization, through sudden cold produced . Food-grade sodium hexametaphosphate edible is required to remove arsenic, heavy metal purification processing after neutralization reaction, then by heated baked melts system. It is used for food quality improver in the food industry, PH value regulator, metal ion chelating agent, dispersant, expansive agent, etc. Standard: GB 1624-7 Item indicators Superior Best-quality Quality Total phosphate (As P2O5) %ï¼Â 68.0 67.0 65.0 Inactive phosphate(As P2O5) % 7.5 8.0 10.0 Water insoluble matter,% 0.05 0.10 0.15 iron(as Fe) % 0.02 0.10 0.20 Ph value 5.8-7.3 5.8-7.3 5.8-7.3 dissolubility Qualified Qualified Qualified Mean degree of polymerization n 10-16 10-16 10-16
