Jiangsu Hengfeng has become a professional production and research and development base for water treatment chemicals and oilfield chemicals in China.

  • In emulsion polymerization processes, how does the choice of emulsifier affect oilfield polyacrylamide?

    The types of emulsifiers have a significant impact on the polymerization efficiency of oilfield polyacrylamide. Emulsifiers, as surfactants, primarily function to reduce the interfacial tension between oil and water, stabilizing the emulsion system to ensure smooth progress of the polymerization reaction. Different types of emulsifiers possess distinct chemical structures and properties, leading t...

  • Anti-Adsorption Effect of Polyacrylamide Chemicals for Papermaking

    The anti-adsorption effect of polyacrylamide (PAM) chemicals for papermaking is the practical ability of PAM to reduce how strongly fibers, fines, and furnish components take up (adsorb/hold) water at their surfaces—so water stays more uniformly dispersed in the stock, improving wet-end stability and controllability. In day-to-day operation, this shows up as fewer “wet clumps,” more even dispersio...

  • How Polyacrylamide Improves Water Retention in Paper Pulp

    Direct answer: what polyacrylamide does to improve water retention in pulp Papermaking polyacrylamide (PAM) chemicals improve water retention in pulp by keeping fines, fibrils, and fillers attached to fibers and by forming a controlled microfloc network that holds water more uniformly in the wet web. In practical terms, the pulp slurry drains more predictably, the sheet forms more evenly, and the...

  • How Cationic Polyacrylamide Emulsion Removes Organics in Wastewater

    Cationic polyacrylamide (CPAM) emulsion removes organic matter from wastewater by converting dissolved and colloidal organics into larger, separable flocs through charge neutralization and polymer bridging. In practice, CPAM works best as a flocculant (or coagulant aid): it binds negatively charged organic particles, emulsified oils, and humic/fulvic substances into dense agglomerates that can be ...
