1 water treatment the application of polyacrylamide in water treatment industry mainly includes raw water treatment, sewage treatment and industrial water treatment. In raw water treatment? Is polyacrylamide combined with activated carbon? It can be used for coagulation and clarification of suspended particles in domestic water. In sewage treatment. Polyacrylamide can be used for sludge dewatering? In industrial water treatment? Polyacrylamide is mainly used as formula medicine. In raw water treatment? Use organic flocculant polyacrylamide instead of inorganic flocculant? Even if the sedimentation tank is not rebuilt? The water purification capacity can also be improved by more than 20%. So when the water supply in many large and medium-sized cities is tight or the water quality is poor? Polyacrylamide as a supplement. In sewage treatment? Using polyacrylamide can improve the utilization rate of water reuse cycle. 2 in the field of oil production, is oil exploitation? Polyacrylamide is mainly used for drilling mud materials and improving oil recovery? Widely used in drilling, completion, cementing, fracturing, oil recovery and other oilfield exploitation operations? It has the functions of increasing viscosity, reducing filtration loss, rheological adjustment, gelation, shunting and profile control. At present, China's oilfield exploitation has entered the middle and late stage? Enhance oil recovery? At present, polymer flooding and ASP flooding are mainly promoted. By injecting polyacrylamide aqueous solution? Improve the oil-water velocity ratio? So as to improve the crude oil content in the product. At present, there are not many applications of polyacrylamide in oil fields abroad. Due to the special geological conditions in China? Polymer flooding technology has been widely used in Daqing Oilfield and Shengli Oilfield. 3 Polyacrylamide is widely used as retention aid, drainage aid and leveling agent in papermaking field. Its function is to improve the quality of paper? Improve the dewatering performance of mud? Improve the retention rate of fine fibers and fillers? Reduce raw material consumption and environmental pollution. The function of polyacrylamide in papermaking depends on its average molecular weight, ionic properties, ionic strength and the activity of other polymers. Nonionic polyacrylamide is mainly used to improve the filterability of pulp? Increase dry paper strength? Improve the retention rate of fibers and fillers? Anionic polymers are mainly used as wet and dry strengthening agents and retention AIDS for paper? Cationic polymer is mainly used for papermaking wastewater treatment and filter aid? In addition, it also has a good effect on improving the retention rate of fillers. Besides? Polyacrylamide is also used for papermaking wastewater treatment and fiber recovery. Textile printing and dyeing industry in textile industry? Polyacrylamide as sizing agent and finishing agent for fabric post-treatment? It can produce a soft, wrinkle-resistant and mildew-proof protective layer. Take advantage of its strong hygroscopicity? Can reduce the yarn breakage rate during spinning? Polyacrylamide as post-treatment agent can prevent fabric from static electricity and flame retardant? When used as a printing and dyeing auxiliary? Polyacrylamide can make the product have high adhesion fastness and high brightness. Can also be used as a stabilizer for bleaching non-silicon polymers? Besides? Polyacrylamide can also be used for efficient purification of textile printing and dyeing wastewater. Other fields are mining and coal washing? Using polyacrylamide as flocculant can promote the sedimentation of solids in mining and coal washing recovery water? Clear water? At the same time, useful solid particles can be recovered? Avoid polluting the environment? In the sugar industry? Can polyacrylamide accelerate the sedimentation of fine particles in sugarcane juice? Promote filtration and improve the clarity of filtrate? In aquaculture? Can polyacrylamide improve water quality? Increase the light transmittance of water? So as to improve the photosynthesis of water? In the pharmaceutical industry? Polyacrylamide can be used as flocculant for separating antibiotics, excipient binder for tablets and clarifier for process water. In the building materials industry? Polyacrylamide can be used as thickener and dispersant for coatings, coolant for sawn stone plates and ceramic adhesive. In agriculture? As a super absorbent material, polyacrylamide can be used as soil humectant and seed culture medium. In the construction industry? Can polyacrylamide enhance the hardness of gypsum cement? Speed up the dehydration of asbestos cement. Besides? Polyacrylamide can also be used as a protective coating for natural or synthetic leather and as a granulation aid for inorganic fertilizers.
I hope to adopt it ~
