White powder, melting point 622 '℃, soluble in water, such as calcium and magnesium metalion chelating abilitysignificantly, can soften hard water, make suspension solution, have a weak alkali, no corrosion, is a kind oiinorganic surface active agent, have a strong emulsification of lubricating oil and fat, low bulk density is usuallydivided into 0.35 0.5 g/cm3 density, medium density 0.51 0.65 g/cm3, 0.66 0.9 g/cm3 density; Five sodium with type(high temperature type) and type ll (low temperature type) two kinds of crystal morphology, its chemical propertiesare the same, the diference is that the thermal stability and moisture absorption type l higher than that oftypel, bothat the same time, the solubility of dissolving hydration heat is diferent. Hydrolysis in water gradually generateorthophosphate, has the good ability of chelating metal ion, it can with metal ions such as calcium, magnesium, iron,complexation, has the nature ofcertain organic surface active agent. |
