III. Conclusion With domestic production technology transitioning from laboratory-scale to batch production, the preparation technology for PAM powder is moving towards higher molecular weight, functionalization, and rapid dissolution. By optimizing polymerization processes and equipment selection, the performance of domestic PAM dry powder has gradually reached advanced international levels, capable of meeting the苛刻 demands of different […]

II. Analysis of Core Preparation Processes Currently, the mainstream process for industrial production of PAM dry powder is the aqueous solution polymerization method. This process includes monomer preparation, polymerization, hydrolysis, granulation, drying, crushing, and screening. 1. Ultra-High Molecular Weight Control TechnologyTo achieve the required molecular weight of over 20 million for oil displacement applications, the polymerization

Abstract: As a linear water-soluble polymer, the preparation process of Polyacrylamide (PAM) powder directly determines its molecular weight, solubility, and application performance. This article aims to explore the preparation technology of ultra-high molecular weight and fast-dissolving PAM dry powder, analyze the key control points of the polymerization process, and provide a reference for technical personnel in
