Amphoteric Polyacrylamide

Overview Specification Benefits Application Areas Notes

Overview

Amphoteric polyacrylamide contains cationic and anionic groups in its molecule. lt possesses the characteristics of common cationic flocculants and exhibits more excellent properties. Such flocculants can be used in a wide range of PH values, with higher water filtration capacity, lower mud cake moisture content, and can also be used for strone acid eaching of ores or recovering valuable metals from acidic catalysts containing metals. Amphoteric polyacrylamide is by no means a mixture of anionic and cationic polyacrylamide.

Benefits

Easily soluble in water, dissolve thoroughly in cold water.

Excellent flocculation effect and low dosage.

High level of water clarification.

Great compatibility with inorganic coagulant.

Wide PH range of application （2-14）

Application Areas

Waste water flocculation and settling

Sludge dewatering

Profile control agent and water shutoff agent in oil industry

Papermaking additive

Notes

Non-toxic, easily soluble in water and easily moisture absorption to caking

Splashes on hand and skin should be washed off with water immediately

Proper storage temperature : 5℃~40℃, should be stored in cool and dry place

Prepared liquid polyacrylamide is not suitable for long storage. The flocculating effect will decrease in 24 hours

Low-hardness water with neutral PH (range 6-9) is suggested to dissolve polyacrylamide. Using underground water and recycled water would decrease the flocculating effect
