The main auxiliaries for synthetic detergent,soapsynergist,leather tanning agent for industrial water softener,paint,kaolin,magnesium oxide,calciumcarbonate drilling mud,etc.dealing with the effective suspension powder,papermaking as anti-oil agent;in the food industry for the canned food,juice drinks,dairy products,soy milk and other quanlity improver,mainly fortenderizing canned ham,broad beans,canned convinces Yuba softening can also be used as softeners and thichening agent.
3 poly-sodium phosphate detergant additive as a fine for half a century has been to serve mankind,to clean the suivival of the human enviroment,enhance the decontamination effect of detergent has played a huge role.
(1) for soft water. Because of its chelation of calcium,magnesium,iron and other metal ions in nature;
(2) as glue solvents,emulsifiers. Of its proteins swelling,solubulization,and therefore solvable glue effect,promote the emulsification of the fatty substance from the fole of the sand,dust and other increase in dispersion of solid dirt,it can enhance the surface activity of surfactants,reduce critical micelle concentration,surfactants play a lower sosage and enhanced detergancy dual role;
(3) as buffer. Even if there is dirt there is acidic,it can maintain a certain degree ot alkalinity washing liquid is conducive to the removal of acidic dirt;
(4) as desiccant. It has to absorb moisture to prevent caking of the role of the detergent,it can maintain a synthetic detergant products has always been to become dry and granular.
