Polyacrylamide is an industrial water treatment flocculant. It is frequently utilised within the production materials sector and constitutes an indispensable component of its manufacturing processes. We are all aware of the profound societal impact of environmental pollution. Consequently, regulatory authorities have introduced a series of regulations in recent years. The state maintains stringent oversight over wastewater discharge, and failure to meet standards will incur significant penalties.
Polyacrylamide boasts a broad spectrum of applications and ranks among the most frequently employed water purification agents. Its primary industrial application lies within the papermaking sector. Firstly, it enhances the retention rate of paper fillers and pigments, thereby reducing raw material wastage and environmental pollution. Secondly, it improves paper strength, dry strength, and wet strength. Furthermore, polyacrylamide improves paper tear resistance and porosity, thereby enhancing visual and printing properties. It is also employed in packaging paper for foodstuffs and tea. Its applications extend to the petroleum industry, including oil extraction, drilling mud, waste mud treatment, preventing water ingress, reducing friction resistance, improving recovery rates, and tertiary oil recovery. In textile sizing, it stabilises slurry properties, minimises slurry loss, reduces yarn breakage rates, and yields smooth fabric surfaces. Polyacrylamide is also extensively employed for thickening, colloid stabilisation, drag reduction, bonding, film formation, and biomedical materials. Other sectors include the food industry, where it clarifies cane juice and beet sugar production, and facilitates phosphoric acid flotation in syrup extraction. In enzyme preparation fermentation, it facilitates flocculation and clarification. It is also employed in feed protein recovery, offering stable quality and excellent performance. The recovered protein powder has no adverse effects on chicken survival rates, weight gain, or egg production. Applications extend to synthetic resin coatings, construction grouting materials for water sealing, the building materials industry for enhancing cement quality, and construction adhesives. It serves as a joint filler, repair agent, and water-stopping compound, alongside uses in soil improvement, electroplating, and dyeing industries.
Certain precautions must be observed when utilising polyacrylamide products. Different polyacrylamide formulations serve distinct applications. Therefore, selection must be based on the target material's physical properties and specific purpose—determining whether cationic, anionic, or non-ionic polyacrylamide is appropriate. This distinction must be clearly understood. One size does not fit all. This approach is highly unscientific. Each application must be addressed individually to maximise economic value.
