Field of application of polyacrylamide
Polyacrylamide is a linear polymer that dissolves easily in water and is nearly insoluble in common organic solvents like benzene, ethylbenzene, esters, and acetone. Its aqueous solution is clear and viscous, making it safe to handle. It is non-toxic, non-corrosive, hygroscopic, and exhibits excellent thermal stability. Let’s explore the wide range of applications for polyacrylamide!
In the water treatment industry, polyacrylamide is one of the most effective materials used for purification. It is widely applied in municipal sewage treatment, industrial wastewater management, and drinking water purification. It helps in removing impurities, improving clarity, and enhancing sedimentation processes. Additionally, it plays a key role in coal washing, mineral processing, metallurgy, and steel production.
In the textile industry, polyacrylamide serves as a sizing agent, finishing agent, and protective coating. It enhances fabric smoothness, prevents wrinkles, and improves mold resistance. Its high hygroscopicity reduces breakage during spinning, while its use as a post-treatment agent helps control static and improve flame resistance. In printing and dyeing, it boosts color fastness and provides stable performance without silicon-based additives.
The petroleum industry also benefits from polyacrylamide. It is used in oil recovery, drilling mud conditioning, and waste sludge treatment. It helps reduce friction, prevent water intrusion, and enhance oil extraction efficiency. In the paper industry, it increases filler and pigment retention, reduces material loss, and improves paper strength—both dry and wet. It also enhances tear resistance, porosity, and printability, making it ideal for packaging materials like food and tea wrappers.
Beyond these sectors, polyacrylamide finds use in the food industry for clarifying cane juice and extracting syrup. It aids in flocculation during enzyme fermentation and protein recovery in feed production. The recovered protein powder is safe and has no negative impact on poultry health or growth. It is also used in synthetic resin coatings, construction grouting, cement improvement, adhesives, soil stabilization, electroplating, and more.
