1. Technical Description

Non-Ionic Polyacrylamide (NPAM) is a water-soluble high-molecular-weight polymer synthesized from acrylamide monomers. Its key characteristic is the absence of ionic charge groups in its molecular chain, resulting in a neutral charge. This property makes it particularly effective in situations where ionic interference is a concern or where its performance is largely independent of the pH and salinity of the medium.

2. Industrial Applications

Wastewater Treatment: Effective flocculant for solid-liquid separation in industrial process water and municipal sewage, especially suitable for acidic or high-salinity conditions. Used in sludge dewatering to increase solid content.
Mining & Mineral Processing: Serves as a flocculant and thickener in tailings treatment, coal washing, and mineral beneficiation processes.
Oilfield Industry: Used as a drilling mud additive for viscosity control and fluid loss reduction.
Textile & Paper Industries: Acts as a sizing agent, coating retention aid, and fiber dispersant.
Agriculture: Functions as a soil conditioner to improve water retention and structure.
Outras utilizações: Gel electrophoresis, chemical grouting, and as a thickening agent in various formulations.
