Application:
Used as main auxiliary of synthetic wash, soap synergistic agent, water softener, leather pre-tanning agent, dye auxiliary agent, and dispersant of suspension such as paint, kaolin, magnesium oxide, calcium carbonate drilling mud, preservative agent for paper making, organic synthesis catalyze, also used in epuration of petroleum product, gum latex storage, as dispersant, solvent in metal industry and pharmaceutical industry.
Character:
It is white powder; Byname is Pent-sodium Phosphate; Melting point is 622°C;It has salient chelating capacity to ions of Ca, Mg etc; It can soften the hard water to make suspension become into the clear solution; it has weak alkalinity but no corrosiveness. It is a surfactant which has outstanding emulsification for lubricants and fat; It has different bulk density, i.e. low density 0.35-0.5g/cm3, medium density 0.51-0.65g/cm3 and high density 0.66-0.9g/cm3.This product has two kinds of crystalline forms, namely Type I (the type of high temperature) and Type II (the type of low temperature). The chemical characters of the two types are the same, and the difference between them lies in the thermo stability.
