Nonionic polyacrylamide (NPAM) is a polymer that is widely used in various fields. This article will introduce its various uses from the aspects of environmental protection, oil extraction, water treatment, and textiles.
1.Sewage treatment.
NPAM is widely used in sewage treatment due to its excellent solid-liquid separation performance. It can be combined with particulate matter and suspended solids to form larger clusters, so as to achieve rapid sedimentation and filtration of sewage and improve the efficiency of sewage treatment. In addition, NPAM can also be used as a sludge dissolving agent to promote sludge settling and thickening, reducing the cost and space occupation of sludge treatment.
2.Water purification.
NPAM also plays an important role in water purification. It can be combined with dissolved organic matter to form macromolecular complexes, thereby purifying organic pollutants in water bodies. In addition, NPAM can also be used as a flocculant in water to promote the sedimentation of suspended solids in the water and improve the transparency and water quality of the water body.
1.Improve well recovery.
In oil extraction, NPAM can be used as a thickener to improve the performance of the injection fluid. It can increase the viscosity of the injection fluid and improve the recovery rate of the well. In addition, NPAM can also be used as a flow regulator to adjust the fluidity of the injection fluid to ensure that the injection fluid is evenly distributed in rock fractures and improve the recovery rate of oil wells.
2.Prevents formation breakage.
NPAM can also be used to reduce the risk of formation rupture. In hydraulic fracturing operations, the addition of NPAM to a water-based liquid increases the viscosity of the water, thereby reducing the occurrence of formation rupture. This not only saves energy and water resources, but also reduces environmental pollution and crustal vibration.
1.Drinking water purification.
NPAM can be used for the purification of drinking water. It can adsorb and precipitate suspended solids, colloidal substances and heavy metal ions in the water body, thereby purifying water quality. In addition, NPAM can also purify the oil and organic matter in the water, improving the safety of drinking water.
2.Desalination and concentration.
NPAM also plays an important role in desalination and wastewater concentration processes. It can be combined with ionic substances to form macromolecular complexes, thereby reducing the concentration of dissolved substances in the water and achieving desalination and concentration effects.
1.Fiber processing aids.
NPAM can be used as an aid in textile processing. It can increase the softness and gloss of textiles, improve the feel and appearance of textiles. In addition, NPAM can also improve the stability and durability of textiles and extend the service life of textiles.
Nonionic polyacrylamide has a wide range of uses, especially in environmental protection, oil extraction, water treatment and textiles. It can be used as a sewage treatment agent, water purification agent and textile processing aid to improve the efficiency and quality of industrial production. At the same time, NPAM can also be used to improve the recovery rate of oil wells, prevent formation fracture and desalination concentration, etc., and play an important role in oil extraction and water treatment.
