Anionic Polyacrylamide (NPAM)

Product Description

Anionic Polyacrylamide Anionic Polyacrylamide: It is the white powder. The APAM with the molecular weight of 4, 000, 000-26, 000, 000 has good water solubility, and it can be dissolved in water by arbitrary proportion but not in organic solvents. It has the characteristics of high-polymer electrolyte in the neutral and alkaline medium, and it is sensitive to the electrolyte salt. And it can be cross-linked into insoluble gel with the high valence metal ions.

Use:
(1) Industrial waste water treatment:
For the neutral or alkaline waste water with pH value of 7-14, large suspended particles and ions of positive charge, it has the best treating effect, such as the waste water from iron industry, electroplating factory, metallurgical industry, coal washing, etc...
(2) Drinking water treatment:
When the drinking water still does not meet the standard after the treatment of the precipitation and filtering, then the APAM can be used as the flocculant. Its dosage is 2%-5% of that of the inorganic flocculants, but the effect of former is dozens of times of that of latter.
(3) It can be used for the recycling of the loss of brewers' grains in the alcohol plant and starch in the starch factory.
(4) It can be used as the water block agent in the oil field, and also the oil-displacing agent during the tertiary recovery.
(5) It can be applied in the paper-making industry. It can be used as the dispersant, retention aid, etc. In the long fiber paper-making, and also the flocculant for the waste water from the paper-making.
