Coordination effect of cationic polyacrylamide on synergistic effect
The latest type of water treatment agent, in many cases when dealing with sewage and water, anionic polyacrylamide and cationic polyacrylamide used in conjunction with the use of an ionic polyacrylamide alone is very significant and synergistic effect, PAM, The surface tension of the trunk can be far greater than the same conditions under the cation or anion alone capacity, in order to achieve the requirement to reduce the surface tension, the need to use both anionic and cationic polyacrylamide, both the use of improper, will produce white precipitate , Loss of use effect. And PAM has the characteristics of zwitterion, it can complete the anion, cation with the synergistic effect, and no precipitation produced, especially for the water quality is more complex or the nature of water often change, the use of PAM as a flocculant more Convenient, the effect is better.
Cationic polyacrylamide in the use of attention to what issues:
1, because the price of cationic polyacrylamide is high, the use of high cost, so from the point of view of cost savings, we must first test to see if they have to deal with the sewage can be used anionic polyacrylamide or other cost is relatively small The flocculant is clean and, if not, consider using cationic polyacrylamide. Before using cationic polyacrylamide, do the experiment, according to their own degree of sewage to choose the most appropriate amount of cationic polyacrylamide, so as not to waste.
2, cationic polyacrylamide in use, without the need to accelerate the dissolution of warm water, cold water can be dissolved.
3, cationic polyacrylamide usually placed in a cool dry place to store, so as not to form a block.
