Industrial pyrophosphate (TSPP) molecular formula Na4P2O7 265.90 specifications conform to HG / T2968-1999; customer requirements 25Kg, 50Kg plastic woven bags; customer use for detergent, bleach additives fine; water treatment agents electroplating, oil drilling and other aspects as quality improver 1. There improve food complexing metal ions, pH, ionic strength effects increase, thereby improving food and water holding capacity of the junction focus. China provides for dairy products, poultry products, fish, meat, ice cream and instant noodles, the maximum use of 5.0g / kg; in canned food, fruit juice (flavored) drinks and vegetable protein drinks maximum usage is 1.0g / kg. Whitener used for potato starch complex, the maximum use of 0.025g / kg. 2. The use as canned food, fruit juice, dairy products and other quality improver, pyrophosphate having a polymerization nature, emulsification, dispersion, prevent fat oxidation, enhance the role of casein sticky, to easily oxidized, fermentation The food is also inhibited. Crystalline and anhydrous sodium pyrophosphate are rarely used alone, generally along with other condensed phosphates formulated into preparations after use. Sodium pyrophosphate and sodium tripolyphosphate mixed preparation can be used as elastic enhancer. You can also use pyrophosphate make miso, soy sauce, bright colors, to prevent their discoloration. At the end fish cooked products, the addition amount of raw meat pyrophosphate 0.05% to 0.3%. 3. used as a plating solution of copper complexes, machining used as herbicides. Hair bleaching powder formulation and insurance auxiliaries, wool degreasing agent. Vegetable fiber bleaching, dyeing and finishing auxiliaries during bleaching. For synthetic detergent builder. Adding an appropriate amount of time in the production of toothpaste with calcium hydrogen phosphate, sodium pyrophosphate and make it a colloid, a stabilizing effect. Chemical production as dispersants and emulsifiers. Water treatment for water softener, boiler detergents. Is the production of other pyrophosphate feedstock. 4. Available the sodium tripolyphosphate or sodium hexametaphosphate mixed in synthetic detergent formulations, promote the improvement of detergency. Pyrophosphate addition to softening of functions, but also re-dissolved calcium and magnesium insoluble salts, such as clothing fibers mixed with dirt insoluble calcium soaps or other metal soap formation, it can be improved decontamination redissolved capacity. In addition, sodium pyrophosphate have deflocculation so that the grease emulsifying effect, which is called peptization properties. Surfactant solution also enables to further reduce the surface tension and interfacial tension, play a role in the washed builder.
