Polyacrylamide (poly(2-propenamide) orpoly(1-carbamoylethylene)) is a polymer(-CH2CHCONH2-) formed from subunits that canalso be readily . Acrylamide needs to be handled using bestlaboratory practice (such as wearing appropriate gloves, lab coatetc. and having safe systems of work) to avoid poisonous exposuresince it is a . Polyacrylamide is not toxic, but unpolymerizedacrylamide can be present in the polymerized acrylamide. Thereforeit is recommended to handle it with caution. In the cross-linkedform, it is highly water-absorbent, forming a soft used in suchapplications as and in manufacturing soft . In the straight-chainform, it is also used as a and agent. More recently, it has beenused as a subdermal filler for aesthetic facial surgery (see ).
Product Description
Polyacrylamide (Polyacrylamide) called PAM, commonly known asflocculants or cohesion agent, sub-cation, anionic, in themolecular weight of between 000 400-1800, product appearance iswhite or slightly yellow powder, soluble in water. Especially theacidic water and the organic acid partial suspension of red mudfrom the flocculation and sedimentation and separation of mud, withlow, low-cost water system, is flocculant other products cannot bereplaced.
Product performance:
1. Mainly used for sludge dewatering, mineral processing, coalwashing and various solid-liquid separation.
2. For a variety of industrial wastewater and sewage treatment.
3. The paper is fine chemicals and oilfield chemicals.
