The manufacturer tells you how to prevent the hydrolysis of industrial grade sodium hexametaphosphate?

 With the increase in the application of phosphate, the role of sodium hexametaphosphate is not limited to washing addition, but more large-scale industrial applications are added by refractory materials and industrial soft water. How to prevent hydrolysis during use? First look at the performance characteristics of sodium hexametaphosphate.


Performance characteristics: white powder or powder, apparent density 0.35-0.90g/cm3, melting point 622 degrees Celsius. soluble in water. The aqueous solution is alkaline, and the pH of 1% aqueous solution is 9.7. It is gradually hydrolyzed into phosphite in water and has a good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. So industrial grade sodium hexametaphosphate can soften hard water. As an inorganic surfactant, it also has the properties of a certain organic surfactant.


It is a kind of sodium metaphosphate polymer, which is transparent glass flake or white powdery crystal. Strong hygroscopicity; it becomes sticky after absorbing moisture, easily damp in the air, and easily soluble in water. The solubility is greater in water, but the dissolution rate is slower. The aqueous solution is acidic. Easy to hydrolyze or become phosphite. It has the ability to form or dissolve complexes for certain metal ions (calcium, magnesium). Therefore, it can be used to soften water, and can also form complexes with lead, silver, and barium salts.


The manufacturer tells you that preventing industrial grade sodium hexametaphosphate from hydrolyzing pH is the key. Chuandong Chemical Group, the manufacturer of sodium hexametaphosphate, has strict control over the production process of sodium hexametaphosphate. It uses genuine phosphoric acid to produce it with few impurities and a clear aqueous solution.
