The phosphate detergent

Phosphate.There are sodium phosphate, disodium hydrogen phosphate, sodium dihydrogen phosphate and melamine acid sodium, widely used in washing powder, sodium tripolyphosphate.Polyvalent metal ion in sodium tripolyphosphate with strong chelating ability, that will not dissolve the polyvalent metal cation complexation, into soluble compound ions, such as the calcium and magnesium ions in the water can be chelate, make them from deposition to the fabric, improved the detergent actives washing efficiency.Sodium tripolyphosphate was of fine inorganic particles or fat droplets have dispersion, emulsification, peptizing effect, can improve the suspension ability of dirt, prevent dirt deposition onto the fabric again, so as to improve the washing effect of the detergent.Because sodium tripolyphosphate contain six water of crystallization, is not easy to absorb moisture, keep good liquidity and can make the washing powder granularity, make the finished product is dry, facilitate the packing, does not produce dust, moisture absorption, as well as the adhesion phenomenon.
