Amphoteric Polyacrylamide

Overview Specification Advantages Application Fields Storage and Precautions

Overview

Amphoteric Polyacrylamide has both cationic and anionic functional groups on its molecular chains. This product combines the dual properties of cationic and anionic flocculants and exhibits superior performance in various application scenarios. It can be used within a wide pH range, with advantages including high filtrate yield and low moisture content of sludge cake. In addition, it can be used for strong acid leaching of ores or recovery of valuable metals from acidic catalysts containing metals. Amphoteric Polyacrylamide products are copolymers with both anionic and cationic groups chemically bonded to the molecular chains, by no means a simple physical mixture of anionic and cationic products.

Wide applicable pH range (2-14).

Application Fields

Sewage flocculation and sedimentation

Sludge dewatering

Oilfield water shutoff and profile modification agent

Retention aid and filter aid for papermaking

Storage and Precautions

The product is non-toxic, water-soluble, and may cake if moistened.

In case of hands or skin contact, rinse immediately and thoroughly with water.

Store in a dry place at temperatures between 5°C and 40°C.

The prepared liquid polyacrylamide solution should not be stored for extended periods. Storage beyond 24 hours may reduce its efficacy.

It is recommended to use low-hardness water with a neutral pH (6-9) to dissolve polyacrylamide. Using groundwater or reclaimed water will result in reduced product effectiveness.
