First of all, the industrial grade sodium hexametaphosphate manufacturer talked about how scale is formed. After the water is heated to boiling, part of the scale evaporates, and calcium sulfate (CaSO₄), which is not easily dissolved, precipitates. The original dissolved calcium bicarbonate (Ca(HCO₃)₂) and magnesium bicarbonate (Mg(HCO₃)₂) are decomposed in boiling water, releasing carbon dioxide (CO₂), and turned into calcium carbonate (CaCO₃) and hydrogen which are difficult to dissolve. Magnesium oxide (Mg(OH)₂) also precipitates, and sometimes MgCO₃ is also formed, thus forming scale.

And the industrial grade sodium hexametaphosphate makes the calcium ions Ca⁺⁺ or magnesium ions Mg⁺⁺ in the hard water enter the sodium hexametaphosphate molecule and become very stable soluble complexes: Na₂[Ca₂(PO₃)₆] and Na₂[Mg₂(PO₃)₆], Ca⁺⁺ or Mg⁺⁺ in this complex is not easy to run out. So sodium hexametaphosphate can effectively complex calcium, magnesium and other metal ions in water, reducing the formation of scale.

Industrial grade sodium hexametaphosphate produced by Chongqing Chuandong Chemical Group is widely used in water treatment, detergent additives, beneficiation industry as flotation agent, refractory, important addition of ceramics, power stations, rolling stock, boilers and fertilizer High-efficiency water softener for plant cooling water treatment, chemical control or anti-corrosion agent, cement hardening accelerator, streptomycin purification agent, cleaning agent for fiber industry, bleaching industry, etc.
