Polyacrylamide has been known as “hundred industry additives”, “universal product”. It is widely used in petroleum mining, water treatment, textile printing and dyeing, papermaking, mineral processing, coal washing, medicine, sugar, breeding, building materials, agriculture and other industries.
1. Water treatment industry
Polyacrylamide in the water treatment industry applications mainly include raw water treatment, sewage treatment and industry water treatment in 3 areas. In raw water treatment, polyacrylamide and activated carbon used in conjunction with the coagulation and clarification of suspended particles in living water; in sewage treatment. Polyacrylamide can be used for sludge dewatering; in industry water treatment, polyacrylamide is mainly used as a formulation agent. In raw water treatment, the organic flocculant polyacrylamide instead of inorganic flocculant, even if the sedimentation tank is not modified, the water purification capacity can be increased by more than 20%. Therefore, many large and medium-sized cities are now using polyacrylamide as a supplement when the water supply is tight or the water quality is poor. In sewage treatment, the use of polyacrylamide can increase the utilization rate of water reuse cycle.
2. Petroleum extraction industry
In oil extraction, polyacrylamide is mainly used in drilling mud materials and improve oil recovery rate, etc. It is widely used in drilling, well completion, cementing, fracturing, enhanced oil recovery and other oilfield mining operations, with viscosity, filtration loss, rheological adjustment, gelling, shunting, profile adjustment and other functions. At present, China’s oilfield mining has entered the middle and late stage, in order to improve the crude oil recovery rate, at present the main promotion of polymer oil drive and ternary composite oil drive technology. Through the injection of polyacrylamide aqueous solution, improve the oil-water flow rate ratio, so that the crude oil content in the extracted material increased. At present, there are not many applications of polyacrylamide in oil fields abroad, and due to the special geological conditions in China, the Daqing Oilfield and Shengli Oilfield have begun to widely use polymer oil drive technology.
3. Paper industry
Polyacrylamide is widely used in the field of papermaking as residing agent, filter aid, homogenizer and so on. Its role is to be able to improve the quality of paper, improve the performance of pulp dewatering, improve the retention rate of fine fibers and fillers, reduce the consumption of raw materials and pollution of the environment. The effect of polyacrylamide used in papermaking depends on its average molecular weight, ionic nature, ionic strength and the activity of other copolymers. Nonionic polyacrylamide is mainly used to improve the filtration of pulp, increase the strength of dry paper, improve the retention rate of fibers and fillers; anionic copolymers are mainly used as wet and dry reinforcement of paper and resident agent; cationic copolymers are mainly used in paper wastewater treatment and filtration aids, and in addition to improve the retention of fillers also has a good effect. In addition, polyacrylamide is also used in paper wastewater treatment and fiber recovery.
4. Textile printing and dyeing industry
In the textile industry, polyacrylamide as a fabric post-treatment sizing agent, finishing agent, can generate soft, wrinkle, mold-resistant protective layer. The use of its moisture absorption characteristics, can reduce the rate of thread breakage when spinning yarn; polyacrylamide as a post-treatment agent can prevent static electricity and flame retardant fabrics; used as a printing and dyeing auxiliaries, polyacrylamide can make the product fastness to adhesion, high vividness, but also as a non-silicone polymer stabilizer for bleaching; in addition, polyacrylamide can be used for textile printing and dyeing wastewater purification of high-efficiency.
5. Mining industry
In the field of mining, coal washing, the use of polyacrylamide as a flocculant can promote mining, coal washing recovery of solids in the water settlement, so that the water is clarified, and at the same time can be recovered useful solid particles, to avoid pollution of the environment.
6. Sugar industry
In sugar industry, polyacrylamide can accelerate the sinking of fine particles in cane juice, promote filtration and improve the clarity of filtrate.
7. Breeding industry
In the aquaculture industry, polyacrylamide can improve the water quality, increase the light transmission performance of water, so as to improve the photosynthesis of water.
8. Pharmaceutical industry
In the pharmaceutical industry, polyacrylamide can be used as flocculating agent for separating antimicrobials, as adhesive for dispensing tablets, and as clarifying agent for traveling water.
9. Construction and building materials industry
In the construction industry, polyacrylamide can enhance the hardness of gypsum cement and accelerate the dehydration speed of asbestos cement;
In addition, polyacrylamide can be used as the protective coating of natural or synthetic leather and the granulation auxiliary of inorganic fertilizer;
In the building materials industry, polyacrylamide can be used as paint thickening and dispersing agent, saw stone plate coolant and ceramic bonding agent.
10. Agriculture
In agriculture, polyacrylamide as a highly absorbent material can be used as soil moisturizing agent and seed culture agent.
