Amphoteric Polyacrylamide

Overview Specification Advantages Application Fields Storage and Precautions

Overview

Amphoteric Polyacrylamide contains both cationic and anionic groups within its molecular structure. It not only retains the application characteristics of conventional cationic flocculants but also demonstrates superior performance. This type of flocculant can operate effectively over a wide pH range, offers higher filtration capacity, produces sludge cake with low moisture content, and can be used for strong acid leaching of ores or recovering valuable metals from metal-containing acid catalysts. It is crucial to note that amphoteric types are by no means mere blends of anionic and cationic varieties.

Advantages

Excellent water solubility, dissolves completely even in cold water.

Compact flocs, low dosage requirements.

High level of water clarification after process.

Great compatibility with inorganic coagulant.

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.
