When use PAM series products, first make up dilute solution, usually 0.01%-0.1%,thus it is easy to mix with treated substance to get the best result. When make up dilute solution, try best to use water that is neutral or doesn’t contain metallic salt. When make up solution, usually the temperature is between 50-60℃. When used as paper-making staying-assist agent, density couldn’t be too high, other-wise the paper size will appear flocculation, usually it is between 100-300 PPM. When used as flocculation agent it is necessary to select type and size of PAM series products according to PH value of treated substance.
(1)Anionic PAM is suitable for higher density, inorganic suspension substance with positive charge and PH value is neutral of basic solution with thick suspension particles 1mm-10mm.
(2) Non-ionic PAM is suitable for separating mixed organic and inorganic suspension, the solution is neutral or acid.
(3) Cationic PAM is suitable for suspension solution with negative charge and containing organic substance.
