The quality of sodium hexametaphosphate is determined according to our own production process. High-quality sodium hexametaphosphate is a white powder crystal, or a colorless transparent glass flake or block solid. Easily soluble in water, insoluble in organic solvents, and the aqueous solution is alkaline. It has strong hygroscopicity. It can gradually absorb moisture when exposed to the air and become a viscous substance. It can form soluble complexes with metal ions such as calcium and magnesium. What is the quality standard of sodium hexametaphosphate? The manufacturer tells you.

There are many methods for synthesizing sodium hexametaphosphate. Look at the process of Chuandong Chemical Group's sodium dihydrogen phosphate method. The genuine soda ash solution and phosphoric acid (thermal method) are neutralized at 80～100℃ for 2h to produce The sodium dihydrogen phosphate solution is concentrated by evaporation, cooled and crystallized to obtain sodium dihydrogen phosphate dihydrate. Heat to 110-230°C to remove 2 crystal water, continue heating to remove structural water, and further heat to 620°C to dehydrate, the resulting sodium metaphosphate melt will be polymerized into sodium hexametaphosphate. Then, it is discharged and quenched from 650°C to 60-80°C to make tablets. After crushing, the finished product of sodium hexametaphosphate is obtained.

Chongqing Chuandong Chemical Group can customize the production of sodium hexametaphosphate according to the indicators set by customers to improve the cost performance.
