What are the types of polyacrylamide?

Oubo Qingdao Oubo Chemical Co., Ltd. specializes in supplying anionic polyacrylamide, cationic polyacrylamide, and nonionic polyacrylamide.

Is polyacrylamide a high molecular polymer?

Polyacrylamide is a high molecular polymer. Specializing in the treatment of various difficult-to-treat wastewater and the treatment of sludge dewatering. (Sludge dewatering generally uses cationic polyacrylamide) It is widely used in municipal sewage and sludge treatment in the paper-making printing and dyeing industry.

What is the standard state of polyacrylamide?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.

Are polyacrylamides toxic?

Although the polymers are relatively nontoxic, for health concerns, the use of polyacrylamides especially in drinking water and also wastewater has been subjected to closer evaluation during the last decade.

What are the uses of polyacrylamides?

Polyacrylamides (PAAm) are used as water purification flocculants , soil conditioning agents , and in many biomedical applications . They also find use as hydrogels including contact lenses. Introduction: PAAm find wide use as water purification flocculants, soil conditioning agents, and in many biomedical applications.

Should polyacrylamides be used in drinking water?

For health concerns, use of polyacrylamides in drinking water has been subjected to closer evaluation during the last decade. Currently, dosage standards are indirectly based on the maximum concentration of acrylamide that would result from use of a commercial formulation of known acrylamide content.
