| What is Anionic polyacrylamide (CPAM) ? |
| Polyacrylamide various percentages can be dissolved in water, especially when the concentration is higher than '70% more that are water-soluble polymers. Molecular Weight does not seem to affect the solubility of water, but the high molecular weight polymer at concentrations exceeding 10% will form a gel-like structure. This is due to the formation of intermolecular hydrogen bonds. (PAM) polyacrylamide insoluble in most organic solvents. Except for a few polar organic solvent, such as acetic acid,chloroacetic acid, ethylene glycol, glycerol, molten urea and formamide. However, the limited solubility of these organic solvents, often require heating, or of little value. Further soluble formamide, hydrazine, ethylene glycol. Because the industry in the form of an aqueous solution applications. |
Flocculation: PAM allows suspended material by charge neutralization, bridge adsorption, since flocculation.
Adhesion: through mechanical, physical, chemical effect, from the stick and action.
Reduction in resistance: PAM can effectively reduce fluid friction, water with traces of PAM can drop resistance 50-80%.
Thickening: PAM have a thickening effect in neutral and acidic conditions, when the PH value is greater than 10 PAM easy hydrolysis, was half a mesh structure, thickening more obvious.
Flocculation principle: PAM used for flocculation, with the kind of floc surface properties, especially dynamic electromechanical, PH value of the viscosity, turbidity and suspension related to the particle surface zeta potential, particle surface polymerization reasons to join oppositely charged PAM, make the move to reduce the potential and cohesion.
Adsorption bridging: PAM molecular chain immobilized on the surface of different particles, forming a bridge between the polymer particles, the particles form aggregates and settle.
Adsorption: various polar groups adsorbed particles PAM molecule.
Enhancement: PAM molecular chain and dispersed by a variety of mechanical, physical, chemical and so on, will be involved with the dispersed phase to form a network, which in turn has enhanced the role.
