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 agent for enhancing oil recovery, etc. For example, during the drilling process, polyacrylamide can act 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 frictional resistance between liquids.
Polyacrylamide is mainly used in water treatment for sewage treatment and sludge dewatering. It can accelerate the sedimentation of suspended particles and promote the clarification and filtration of sewage. For example, in the treatment of wastewater from steel mills, electroplating plants and coal washing, polyacrylamide adsorbs suspended solid particles in the water to form large flocs, thereby accelerating the clarification and filtration of the solution.
Polyacrylamide is mainly used in the papermaking 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, thereby improving the quality and printing performance of paper.
In the textile industry, polyacrylamide is used as a sizing agent to stabilize the slurry properties, reduce slurry loss and fabric breakage rates, and make the fabric surface smoother.
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.
