Polyacrylamide classification polyacrylamide Products Description: Polyacrylamide (PAM) is a water-soluble polymers do not dissolve in most organic solvents, good flocculation, can reduce the frictional resistance between the liquid ion characteristics can be divided into four types of non-ionic, anionic, cationic and amphoteric 
 Chinese Name: polypropylene amide Chinese pronunciation: jù bǐng xī xīan ān English name: Polyacrylamide referred to as: PAM PAM is a water-soluble polymers do not dissolve in most organic solvents, has good flocculation, water can be lowered between friction resistance, ion characteristics can be divided into non-ionic, anionic, cationic and amphoteric four types of polyacrylamide Note: [2] 
 1, the floc size: floc is too small to affect the speed of drainage, the floc too large to make the floc constraints more water and reduce the mud biscuits degree. Selected the molecular weight of polyacrylamide can adjust the size of the floc. 
 2, the sludge characteristics. The first point to understand the source of the sludge characteristics and composition, the proportion of According to the different nature of the sludge can be divided into organic and inorganic sludge of two kinds. Used to dispose of organic sludge cationic polyacrylamide, anionic polyacrylamide flocculant for inorganic sludge, cationic polyacrylamide with highly alkaline, the acid is strong, should not use anionic polyacrylamide, solid content The sludge is usually high, the amount of polyacrylamide. 
 3, the strength of the flocs: floc shearing should adhere to the stable and not broken. Progress polyacrylamide molecular weight or the appropriate choice of the molecular structure contribute to the progress of floc stability. 
 Ion degrees of polyacrylamide: dehydrated sludge can be used to stop the selection of different ionic flocculant after the first a small test to select the best suitable polyacrylamide, so that the best flocculant effect, also enable the dosage at least, to save capital. 
 Polyacrylamide dissolved: dissolving hair with plenty of good talent to play flocculation. Sometimes needs to speed up the dissolution rate, when thinking about the progress of the polyacrylamide solution concentration.
