•Introduction
Nonionic Polyacrylamide Polymer
Water Treatment Chemical Polyacrylamide is shorten for PAM,or so called Flocculating Agent. It's a linear water-soluble polymer with high molecular weight.Welcome your inquiry about our products!

2-3 | ≥90 | 1-8 | ≥3 | ≤0.05 | 0.5 |
4-5 | ≥90 | 1-8 | ≥3 | ≤0.05 | 0.5 |
6-9 | ≥90 | 1-8 | ≥3 | ≤0.05 | 0.5 |
≥10 | ≥90 | 1-8 | ≥3 | ≤0.05 | 0.5 |
•Application
It is mainly used for: solid-liquid separation in mineral separation, metallurgy, chemical and food industries, etc.; the sewage treatment of iron and steel, textile, paper-making, chemical and pharmaceutical industries, etc.; the drilling in oil industry and enhancing in oil recovery; as retention reagent and filter aid, reinforcing agent in paper-making; the treatment and purification of urban sewage and potable water.
•Attention
1.The dry powder should be confected into aqueous solution before using of some consistency to ensure its using effect.
2. Polyacrylamide added should according to the polluted water practical situation.
3. The specific operation of confection are as follows: add certain amount of water into the dissolving jar, then start the blender and sift the dry powder around the vortex of water equably. The speed of blending is about 200 recolution/min. And it should be noticed that agglomeration should be avoided after the dry powder particles get into water.Generally speaking, it can dissolve completely after 60's blending.
4. The water which dissolves polyacrylamide is good to be tap water at normal temperature. Improving the temperature suitably can speedup dissolution, but the water temperature should not surpass 50℃, or the polymer will produce heat-degradation when the temperature is too high, the using effect will be influenced as well.
5. The dry powder state PAM can be stored for over 2 years in dry,dark and cool place, but it is not suitable to be stored after being confected into solution. Solution of negative ion and nonion commonly can be stored no more than one week, while solution of positive ion commonly can be stored no more than two weeks.
6. Ferric ion is the catalyzer which causes polyacrylamide. So in confection, transfer and storage the solution of polyacrylamide, contact between the solution and ferric and ion should be avoided. Stainless steel, glass fiber reinforced plastics, etc. Made device the best choice for confecting polyacrylamide solution.
7.Polyacrylamide is non-poisonous and non-corrosive. If it is stuck to the skin, eye or inhaled into the mouth, water should be used in time to rinse it out.nhancer chemicals used in papermaking.
