Product Introduction
Sodium hexametaphosphate is a kind of sodium phosphate polymer, which is transparent glass flake or white powder crystal. Strong hygroscopic, becomes sticky after hygroscopic, easy to be humid in the air, easy to dissolve in water, the solubility in water is large, but the dissolution rate is slow, and the aqueous solution is acidic. It is easy to hydrolyze into phosphite, and has the ability to generate soluble complexes for some metal ions (calcium, magnesium), so it can be used to soften water, and lead, silver, salt, etc., can also generate complexes.
