In areas with hard water quality, the washing effect of detergents will be very poor, and some lands will also lack of phosphorus, and phosphate resources lack of corresponding alternative varieties; sodium hexametaphosphate industrial grade is widely used in water treatment, detergent additives, mineral processing industry as flotation agents, refractory additives, ceramics and other important additives.

Using sodium hexametaphosphate industrial grade with soft water for clothing washing, the water quality is neutral. Washing clothes with soft water can increase the ability of decontamination and make them cleaner and brighter.

When the calcium ion Ca⁺⁺ or magnesium ion Mg⁺⁺ which determines the hardness in water enters into the sodium hexametaphosphate molecule, it will become a very stable soluble complex: Na₂〔Ca₂(PO₃)₆〕 and Na₂〔Mg₂(PO₃)₆〕. The Ca⁺⁺ or Mg⁺⁺ in this complex is not easy to run out again.

The sodium hexametaphosphate industrial grade produced by Chongqing Chuandong chemical Group is made from the genuine raw material made from the phosphate rock of our own fine phosphate mine by thermal process, with uniform particles, less impurities, better flow rate and less consumption.
