Application of Polyacrylamide in water treatment industry mainly includes raw water treatment, sewage treatment and industrial water treatment 3 aspects. In raw water processing, the use of polyacrylamide and activated carbon with suspended particles, can be used for water condensation and clarification; in sewage treatment. Polyacrylamide can be used for sludge dewatering; in industrial water treatment, polyacrylamide is mainly used as pharmaceutical formulations. In raw water processing, using organic flocculants polyacrylamide instead of inorganic flocculants, even if does not transform the sedimentation pond, water purification ability can be improved by more than 20%. So now many large and medium-sized city in the shortage of water supply or the water quality is bad, all using polyacrylamide as a supplement. In wastewater treatment, using polyacrylamide can increase the use rate of water reuse cycle.
2 .oil field
In oil exploitation, polyacrylamide is mainly used for drilling mud material and production rate increase, widely used in drilling, completion, cementing, fracturing, enhanced oil recovery operations such as oil exploration, with increasing viscosity, filtration, flow regulation, gelling, shunt, profile adjustment function. At present, China has entered the oil exploitation in the later period, in order to improve the oil recovery, is mainly to promote the polymer flooding and the three element composite flooding technology. By injecting polyacrylamide aqueous solution, improve the oil flow ratio, so that theproducedcrude oil content increased. There are not many foreign polyacrylamide application in oil fields, as the special geological conditions in China, Daqing and Shengli Oilfield have begun extensive use of polymer flooding technology.
3. papermaking field
Polyacrylamide is widely used in the paper field resident agent, filter aid, evenness agent etc.. Its role is to improve the quality of paper, pulp dewatering to improve performance, increase the fines and filler retention, reduce raw material consumption and environmental pollution etc.. On polyacrylamide effects used in the paper to its average molecular weight, ionic properties, ionic strength and activity of other copolymers. Non ionic polyacrylamide is mainly used to improve the filter paper pulp, and increase dry paper strength, improve the fiber and filler retention; anionic copolymer is mainly used for dry and wet paper reinforcing agent and resident agent; cationic copolymer is mainly used for the treatment of papermaking wastewater and filter for use, in addition to the improved filler retention also better effect. In addition, PAM was also used in the papermaking wastewater treatment and reclaimed fibre.
4. textile printing and dyeing industry
In the textile industry, after polyacrylamide treated as a fabric sizing agent, finishing agent, can generate smooth, wrinkle resistance, mold protection layer. Use of the absorbent characteristics, can reduce the rate of broken when spun yarn; polyacrylamide as finishing agent can prevent electrostatic and flame retardant fabric; used for printing and dyeing auxiliaries, PAM can make the product adhesion fastness, Xian Yandu high, also can be used as the silicon polymer stabilizers bleaching; in addition, polyacrylamide can also be used for efficient purification of textile printing and dyeing wastewater.
5 .other areas
In mining, coal field, settlement by polyacrylamide flocculants can promote the recovery of mining, coal washing water of solids, make the water clear, at the same time the solid particles useful recovery, avoids the pollution to the environment; in the sugar industry, polyacrylamide can accelerate the sinking of fine particle in sugarcane juice, promote filtering and improve filtrate clarity; in the breeding industry, polyacrylamide can improve water quality, increase the light transmission properties of water, so as to improve the water photosynthesis; in medical industry, polyacrylamide is used as flocculant, separation of antibiotics used as tablets shaping adhesive and process water clarifying agent; in the building materials industry, polyacrylamide is used as coating thickening, dispersing agent sawing stone plate coolant and ceramic bonding agent; in agriculture, polyacrylamide as high water absorbent materials can be used as a soil moisturizing agent and seed culture agent etc..
In the construction industry, the polyacrylamide can enhance the hardness of gypsum cement, asbestos cement to accelerate the dehydration rate. In addition, the polyacrylamide can also be used as a natural or synthetic leather protective coating and additives such as inorganic fertilizer granulation
