| 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 facilitates the aggregation of suspended materials through charge neutralization and bridge adsorption, a process known as flocculation.
Adhesion: This process involves mechanical, physical, and chemical interactions that lead to enhanced adhesion.
Reduction in resistance: PAM significantly diminishes fluid friction, allowing water with minimal PAM content to experience a reduction in resistance by 50-80%.
Thickening: PAM exhibits a powerful thickening effect in neutral and acidic conditions. When the pH value exceeds 10, PAM undergoes hydrolysis, forming a semi-mesh structure that enhances thickening effects.
Flocculation principle: In flocculation applications, PAM interacts with surface properties of flocs, focusing on dynamic electromechanical aspects, pH levels, viscosity, turbidity, and suspension. By adding oppositely charged PAM, zeta potential is reduced, enhancing cohesion and particle stability.
Adsorption bridging: PAM's molecular chains anchor onto various particle surfaces, creating bridges among polymer particles, which results in particle aggregation and settlement.
Adsorption: PAM molecules, with diverse polar groups, effectively adsorb onto particle surfaces.
Enhancement: PAM's molecular chains disperse through mechanical, physical, and chemical mechanisms, forming a network with the dispersed phase that enhances structural integrity.
