sodium pyrophosphate has two kinds, anhydrous and decahydrate, so the price is slightly different, of course, the quality is certainly different. yucai chemical Industry produces high-purity and high-content national standard products with reasonable price, good use effect and guaranteed quality.
irst, the production process
Sodium pyrophosphate is obtained by drying anhydrous sodium hydrogen phosphate solution by using an aqueous solution of disodium hydrogen phosphate, and then dehydrating and polymerizing at a high temperature. Two-step method and two-step method, drying and polymerization in one device is called one-step method, and drying and polymerization are done in two devices called two-step method. The one-step method is simple, the process is short, but the quality is not stable. The two-step method is more complicated, the process is longer, and the product quality is more stable. The food industry uses a two-step method for sodium pyrophosphate. The reaction formula is:
Na2HP04·12H20→Na2HP04+12H20
2Na2HP04→NaIP207+H20 [3]
Of course there are other production processes, so buy pyrophosphate to see the treatment effect. Yucai Chemical's domestic phosphate manufacturers for more than 30 years have guaranteed quality, and customers all over the country are welcome to visit them.
