Cationic Polyacrylamide Powder(CPAM)

Product Information

        Polyacrylamide (PAM for short) is a commonly used artificial flocculant. It is easily soluble in water and easily decomposed when the temperature exceeds 120°C. The product has properties such as flocculation, thickening, shearing, drag reduction, and dispersibility. The solid is white or slightly yellow powder, the liquid is colorless and viscous, and the colloidal product is colorless and transparent. Anionic, cationic, nonionic, and zwitterionic polyacrylamide can be obtained by chemical modification.

       The homopolymer formed by the polymerization of a single acrylamide is nonionic, and its molecules are not charged. The copolymer formed by the copolymerization of acrylamide and anionic monomers (such as sodium acrylate) is anionic, and its molecules are negatively charged. For the same reason, the copolymer generated by acrylamide and cationic monomers is cationic, and its molecules are positively charged.

      The copolymer contains some ionic monomers, which shows partial ionic characteristics. We use the percentage of ionicity to express the charge on the polymer molecular chain. The higher the ionicity, the more charged the molecular chain is. In this way, the ionicity of nonionic polyacrylamide is zero. What charge (i.e. ionicity) and how much charge (i.e. ionicity) the polyacrylamide molecular chain carries are important considerations when selecting polyacrylamide flocculants.

        Polyacrylamide is a synthetic polymer with a relatively high molecular weight. The molecular weight of polyacrylamide always refers to the average molecular weight, which indicates the average length of each polymer molecule. The larger the molecular weight, the more chain segments each molecule contains, or the longer the average length of each molecule. From the perspective of molecular weight, the flocculation effect of polyacrylamide is not only related to the molecular weight, but also to the molecular structure (straight chain, branched chain, cross-linked) and molecular weight distribution (wide, narrow).

       Cationic polyacrylamide is a polyacrylamide with cationic groups and active adsorption groups on the molecular chain. It reduces the potential in the water through the action of electrical neutralization, adsorption and bridging, making the suspended particles and negatively charged water-soluble substances in the water unstable, flocculated, and forming larger floccules, so that the suspended matter settles or floats, thereby achieving the purpose of purifying water. It has the functions of decolorization, adsorption, deturbidity removal, and adhesion.

Application:

1. Alcohol factory/MSG factory/sugar factory/meat factory/beverage factory: 0.3%, 3-5g per ton.

2. Textile factory/printing and dyeing factory: can be used for dehydration of residual activated  sludge from printing and dyeing
    wastewater, and can  also be used as a printing and dyeing  decolorization flocculant (weak cationic polyacrylamide)

3. Paper mill: can be used as a papermaking flow aid and filter aid. Papermaking wastewater treatment should first add polyaluminum
    chloride, then polyacrylamide.

4. Pharmaceutical wastewater: strong cationic polyacrylamide (above 60 degrees)

5. Municipal sewage treatment: cationic polyacrylamide (about 50 degrees)

6. Filter press: medium and high cationic polyacrylamide

7. Leather factory: cationic polyacrylamide (above 50 degrees)

8. Thermal power plant: cationic polyacrylamide

9. Phosphating wastewater: first add lime milk to adjust the pH, then add polyacrylamide.

10. Pharmaceutical wastewater: can be used in the production fermentation process in the pharmaceutical process (0.2%)

Cationic polyacrylamide (CPAM) is suitable for the treatment of wastewater containing fine suspended matter, organic matter and colloid due to its unique side chain structure and high density charge.		Textile factory/printing and dyeing factory: can be used for dehydration of residual activated  sludge from printing and dyeing wastewater.
Cationic polyacrylamide can effectively flocculate waste pulp, and form a dense structure, large particles of flocculant, so as to make the paper dense and uniform under the condition of not affecting the paper water filtration performance and retention. In addition, cationic polyacrylamide can resist high shear forces, so it will play a good role in retention and filtration over a wide pH range. The dissolution degree of CPAM has a great influence on the coating and aggregation degree of gold nanoparticles on the surface of paper. CPAM with high charge density dissolves faster and can make the coating and aggregation of gold nanoparticles on paper more uniform and stable.		Sludge colloidal particles are usually negatively charged, and the process of interaction with cationic polyacrylamide is the process of colloidal instability. Polymer cationic groups attract negatively charged sludge ions, reduce and neutralize the surface charge of colloidal particles, and compress the colloidal diffusion layer to make the particles condense and destabilize, and with the help of polymer chain bonding bridging effect, flocculation sedimentation is generated.
