The production practice shows that the molecular weight of the anionic polyacrylamide (APAM) which is used as the dispersant should not be less than 700 x 10 4, and should not be affected by the heat and the high shear force, furthermore, it
Nonionic Polyacrylamide Flocculant - Sinoloc Supplier
Nonionic Polyacrylamide could be used in sand prevention and sand fixation through spraying on desert with dissolving nonionic polyacrylamide concentration and crosslinking agent. This product could also be used as soil moisturizer and the basic
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
Synthesis, Characterization, and Flocculation Properties of Branched Cationic Polyacrylamide
The intrinsic viscosity of polymer was the highest when the concentration of monomer was 35%; after that, the intrinsic viscosity and rates of production decreased. Figures 9 and 10 are the curves of the flocculation performance of branched
3. The concentration of cationic polyacrylamide is generally 2 ‰ to 5 ‰. The concentration of anionic and nonionic polyacrylamide is generally 1 ‰ to 2 ‰. Generally, the dissolution time of cations and anions is about one hour, and that of
RHEOLOGICAL STUDY OF CATIONIC POLYACRYLAMIDE AND COMPARISON WITH ANIONIC HPAM
The critical concentration (C*), which separates the semi-dilute and the dilute regions in a graph of the apparent viscosity versus polymer concentration, was obtained as a function of the shear rate.
Anionic polyacrylamide amine has high water solubility and highmolecular chain viscosity, which can improve the mobility ratio of displacementfluid... 01,2025 Coalwashing polyacrylamide washing is a kind of industrial polyacrylamide.

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- Is acrylamide a cationic flocculant?
- The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
