Polyakryyliamidia

Polyakryyliamidi, often abbreviated as PAM, is a synthetic polymer formed from the polymerization of acrylamide. It is a water-soluble macromolecule that exists in various forms, primarily anionic, cationic, and non-ionic, depending on the presence of charged groups along its polymer chain. The molecular weight of polyacrylamide can vary significantly, ranging from a few thousand to several million grams per mole, which influences its properties and applications.

PAM's solubility in water is a key characteristic that makes it useful in many industrial processes. Its ability to interact with water molecules allows it to act as a thickening agent, flocculant, or binder. The specific properties of a PAM product, such as its charge density and molecular weight, are tailored to the intended application.

In wastewater treatment, PAM is widely used as a flocculant. It helps to aggregate small suspended particles into larger flocs that can be easily removed by sedimentation or filtration. This process enhances the efficiency of water purification. PAM also finds applications in the oil and gas industry, where it is used to improve the viscosity of drilling fluids and in enhanced oil recovery techniques. Furthermore, it is employed in the paper industry as a retention aid and drainage enhancer, and in agriculture as a soil conditioner to improve water retention and reduce erosion. The versatility of polyacrylamide stems from its tunable properties and cost-effectiveness, making it a valuable material across numerous sectors.
