The appearance of polyacrylamide are white particles how to identify the model yet

There are 4 easy ways to tell the polyacrylamide model:
We all know that polyaminoacrylates are the most expensive cation on the market, and nonion is slightly more expensive than anion. We can understand the price alone on the ion type can know a little.
2, the polyacrylamide dissolved polyacrylamide solution PH value, the various types of corresponding pH is different. Practice found that different manufacturers of polyacrylamide products and production processes of raw materials corresponding to different pH values are not always absolute.
Inferred from the sewage experiment, we all know that the general polyacrylamide anionic PAM is suitable for high concentration of positively charged inorganic suspended solids, as well as coarse particles (0.01-1mm), pH is neutral or alkaline Cationic polyacrylamide PAM for negatively charged, organic matter-containing suspended solids; non-ionic polyacrylamide PAM suitable for organic and inorganic mixed state separation of the suspension, the solution was acidic or neutral. Cationic polyacrylamide flocs formed large and relatively dense, anionic and non-ionic floc formed small and scattered.
4, first select an anionic polyacrylamide and a cationic polyacrylamide product, respectively, for drug treatment, the polyacrylamide solution to be tested were mixed with the two PAM solutions, and if the anionic polyacrylamide The product reacts to indicate that the polyacrylamide is cationic and, if reacted with the cation, proves that the PAM product is an anionic or non-ionic product. The disadvantage of this method is the inability to accurately identify whether the product is anionic or non-ionic polyacrylamide . However, we can judge from their dissolution time that the anion dissolves much faster than the nonion. An ordinary anion completely dissolved an hour, while non-ion to an hour and a half.
