Application in the oil industry:
Polyacrylamide has a wide range of applications in the oil industry. It can be used as a drilling mud treatment agent, a water plugging agent, an oil recovery agent, etc. For example, in the drilling process, polyacrylamide can be used as a clay stabilizer and suspending agent to help stabilize the well wall and improve drilling efficiency. In secondary and tertiary oil recovery, polyacrylamide can increase oil recovery by reducing the friction resistance between liquids.
Application in water treatment:
Polyacrylamide is mainly used in sewage treatment and sludge dewatering in water treatment. It can accelerate the sedimentation of suspended particles and promote the clarification and filtration of sewage. For example, in the treatment of steel mills, electroplating plants and coal washing wastewater, polyacrylamide adsorbs suspended solid particles in the water to form large flocs, thereby accelerating the clarification and filtration effect of the solution.
Application in the paper industry:
Polyacrylamide is mainly used in the paper industry to improve the retention rate of fillers and pigments and enhance the strength of paper. By improving the flocculation of pulp, polyacrylamide can reduce the loss of raw materials, improve the dry and wet strength and tear resistance of paper, and thus improve the quality and printing performance of paper.
Application in the textile industry:
In the textile industry, polyacrylamide is used as a sizing agent to stabilize the slurry performance, reduce the slurry drop and fabric breakage rate, and make the fabric surface smoother.
Application in other industries:
Polyacrylamide is also widely used in food, feed, building materials, medicine and other fields. For example, in the food industry, it is used to clarify syrup; in the building materials industry, it is used to improve the quality of cement; in the medical field, it is used to stabilize drug preparations; in agriculture, it is used for soil improvement and plant protection.
