Specifications
odium tripolyphosphate is indispensable in detergent additives, fine most of the content of 10 ~ 50% of detergent.Its main role can be summarized as follows.(1) of metal ion chelation: daily washing water, generally contain to hard metal ions (mainly Ca2 +, magnesium 2 +).In the process of washing, they will work with soap or detergent actives in the formation of insoluble metal salts, in this way, not only increase the consumption of detergent, but also makes the fabric after wash has unpleasant dark gray.Sodium tripolyphosphate with hard metal ion chelating to excellent performance, which can eliminate the adverse effect of these metal ions.(2) improve solubility, emulsifying and dispersing effect: dirt often contains the human body secretions (mainly the protein and fat), also containing sand, dust and so on from the outside world.And sodium tripolyphosphate for protein with swelling, solubilization and peptization effect;Of fatty substances can play the role of promoting emulsion;Suspension of solid particles are dispersed.3) cushion: sodium tripolyphosphate have larger alkaline buffer effect, keep washing solution pH value at around 9.4, which benefits the removal of acid dirt.(4) to prevent agglomeration effect: synthetic detergent powder with hygroscopicity, such as stored in a humidity is bigger, lump phenomena will happen.Extremely inconvenient when using agglomerate of detergent.The water absorption after the formation of the six hydrate, sodium tripolyphosphate with dry properties.When there is a tremendous amount of sodium tripolyphosphate detergent formulation, and can prevent the caking phenomenon caused by moisture absorption, keep the dry granular synthetic detergent.
