Properties：White powder, melting point622℃，easily soluble in water, has a significant integration ability for metal ions such as calcium and magnesium, can soften hard water, turn suspensions into solutions, has weak alkalinity, is non-corrosive, is an inorganic surfactant, has a strong emulsifying effect on lubricating oil and fat, and the bulk density is usually divided into low density0.35-0.6g/cm³，medium density 0.6-0.8g/cm³, high density 0.8-1.0g/cm³: There areItype(high temperature type)andIItype(low temperature type)two crystalline forms, both with the same chemical properties, differing only in thermal stability and hygroscopicityItype is higher thanIItype, and the solubility and heat of hydration during dissolution are also different.
