Polyacrylamide (PAM)

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene)) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits that can also be readily cross-linked. Acrylamide needs to be handled using best laboratory practice (such as wearing appropriate gloves, lab coat etc. and having safe systems of work) to avoid poisonous exposure since it is a neurotoxin. Polyacrylamide is not toxic, but unpolymerized acrylamide can be present in the polymerized acrylamide. Therefore it is recommended to handle it with caution. In the cross-linked form, it is highly water-absorbent, forming a soft gel used in such applications as polyacrylamide gel electrophoresis and in manufacturing soft contact lenses. In the straight-chain form, it is also used as a thickener and suspending agent. More recently, it has been used as a subdermal filler for aesthetic facial surgery (see Aquamid).

Product Description

Polyacrylamide (Polyacrylamide) called PAM, commonly known as flocculants or cohesion agent, sub-cation, anionic, in the molecular weight of between 000 400-1800, product appearance is white or slightly yellow powder, soluble in water. Especially the acidic water and the organic acid partial suspension of red mud from the flocculation and sedimentation and separation of mud, with low, low-cost water system, is flocculant other products cannot be replaced.

Product performance:
1. Mainly used for sludge dewatering, mineral processing, coal washing and various solid-liquid separation.
2. For a variety of industrial wastewater and sewage treatment.
3. The paper is fine chemicals and oilfield chemicals.
