The application areas of polyacrylamide(flocculant)
Well drilling mud raw materials:
in oil field exploration and development and exploration of geology, water and coal, it is used as adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve the drill speed and drilling
footage, and reduce plugin replacing drill, and has prominent well slough preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
Industrial Waste Water Treatment:
Water sources of many tap water factories come from rivers, the sand and mineral contents are higher, water is muddy, the water still can not achieve demands although passing through sedimentation and filtration, and flocculating agent needs adding; however huge adding amount generates increased mud amount and bad effect. The adding amount is only 1/50 of inorganic flocculating agent if anionic-polyacrylamide is adopted as flocculating agent, but the effect is several times better than the organic flocculating agent, and even dozens of times.
Textile Auxiliary Agent:
Polyacrylamide can be added with some other chemicals to prepare chemical grout, is used to starch textiles, can improve the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, and falling objects.
Polyacrylamide can be used as fining agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent in paper-making industry
Polyacrylamide can be used in coal washing tailing centrifugal separation, can be used in sedimentation and filtration
of coal powder and coal mud, and can improve the recovery rate of coal powder and the filtration speed.
Sewage Water Treatment:
When sewage water systems are acidophilic, it is more suitable to select nonionic-polyacrylamide, polyacrylamide can be matched with flocculating agent PAC, aluminium sulphate and the like, and it has the best effect in water treatment.
Metallurgical Mineral Dressing:
It can be used in floatation and smelting of Zinc, manganese and copper mines, its leachate and slag can be added into PAM to improve the separation efficiency.
Sand Prevention and Solidification:
The nonionic-polyacrylamide is dissolved into 0.3% concentration, cross-linking agent is added, and polyacrylamide can be sprayed on desert to prevent and solidify sand.
Chemical mudding agent:
9.5 share nonionic-polyacrylamide is used and is mixed to 0.5share NN-methylene diacrylamide, polyacrylamide can be used as chemical mudding agent for plugging water of dikes, ground foundation, channels and the like.
Oil field profile controlling and water-plugging agent:
Polyacrylamide can be matched with lignocellulose, a certain amount of chemical
adhesive can be added, and polyacrylamide can be used as oil field profile controlling and water-plugging agent.
It can preserve water and solidify sand for soil and can play a role of humectant on slope grass planting, tree planting and sand solidification and dust prevention of soil.
