Preparation:
PhosphateWithSodaIn and to a certainDisodium hydrogen phosphateAndSodium dihydrogen phosphate(2:1), the ratio of the mixture to dry (get orthophosphate dry material), and then at 350 ~ 450 ° C under polymerization generates sodium tripolyphosphate, and then by cooling, crushing, obtained Tripolyphosphate sodium finished product.
4Na2HPO4 + 2NaH2PO4 →2Na5P3O10 + 4H2O
Application:
1) .as one of the main auxiliaries for synthetic detergent, synergist for soap; water softener.
2).Tanning agent for leather making, auxiliary for dyeing;
3).As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.;
4).As an oil contamination resistance agent in paper production.
