Mitsubishi Chemical cationic polyacrylamide 


 Cationic polyacrylamide (CPAM) is a linear polymer, because it has a variety of lively group, with many substances affinity adsorption to form hydrogen bonds. Mainly negatively charged colloidal flocculation, with turbidity, bleaching, adsorption, adhesion and other functions, for dyeing, paper making, food, construction, metallurgy, mineral processing, coal, oil, aquatic products processing and fermentation of organic colloids, etc. higher levels of wastewater treatment, especially for urban sewage, sewage sludge, paper sludge and other industrial sludge dewatering. 

 Second, technical indicators 

 Appearance: white granules or powder; 
 MW :300-15000000 
 Cationic degree: 5% - 80% 



 Third, the application areas 

 1, as a flocculant, mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration and sludge dewatering process, application of the major sectors are: urban sewage treatment, paper industry, food processing, petrochemical industry , metallurgical industry, mineral industry, dyeing industry and the sugar industry and a variety of industrial wastewater treatment. Used in urban sewage and meat, poultry, food processing wastewater sludge during sedimentation and sludge dewatering, through its positive Heji group contained in the negative charge on the sludge organic colloids and the role of electricity in the excellent pool and polymer bridging function to promote aggregation of colloidal particles large floc, separated from its suspension. Effect is obvious, adding less. 
 2, can be used in the paper industry in the dry paper strength agent, retention aid, filter aid, can greatly improve the paper quality, save costs and improve the production capacity of paper mills. Directly with the inorganic ions, organic polymer fibers, and other place in order to achieve enhanced electrostatic bridge the physical strength of the paper, reducing the loss of fiber or filler to speed up treatment, from increased retention, drainage effect, can also be used white water treatment, while in the deinking process can play significant flocculation. 
 3, fiber slurry (asbestos - cement products) in the can forming asbestos - cement products has been improved drainage, the asbestos blank strength; in the insulation board can improve the binding capacity of additives and fibers. 
 4, in the mining, coal preparation industry can be used for mine waste, coal washing waste water clarifier. 
 5, can be used for dyeing wastewater, tannery wastewater, oily wastewater treatment, so that turbidity removal, color removal, to meet emission standards. 
 6, in the purification of phosphoric acid, phosphoric acid process helps the separation of gypsum. 
 7, river water used to water plants water treatment flocculant. 


 Storage, transportation note: 

 1, the product is nontoxic, pay attention to moisture, rain, avoid sun exposure. Storage period: 2 years. 2, Packing: 15/25KG kraft paper bags 
 Polyacrylamide 
 Because of polyacrylamide and its water-soluble polymer main chain acyl lively, and thus in the oil extraction, water treatment, textile 



 Printing and dyeing, paper making, mineral processing, coal washing, medicine, sugar, farming, building materials, agriculture and other industries with a wide range of applications, the "additives businesses," 



 "Universal product," said. 
 A water treatment 
 Polyacrylamide in water industry applications include raw water treatment, sewage treatment and industrial water treatment three aspects. In the original water treatment, 



 Polyacrylamide used in conjunction with activated carbon, etc., can be used for condensation of particles suspended in the water of life and clarifications; in sewage treatment. Polyacrylamide 



 Can be used for sludge dewatering; in industrial water treatment, pharmaceutical formulations mainly used for polyacrylamide. In the original water treatment, polypropylene with organic flocculants 



 Ene amide instead of inorganic flocculants, if not transformation settlement pool, water capacity can be increased by 20% or more. So now in the water supply in many cities 



 When tension or poor water quality, are supplemented by polyacrylamide. In sewage treatment, the use of polyacrylamide to increase the water reuse cycle 



 Usage. 
 2 Petroleum oil field 
 In the oil exploitation, PAM is mainly used for drilling mud material and Enhanced Oil Recovery, etc., are widely used in drilling, completion, solid 



 Well, fracturing, enhanced oil recovery and other mining operations in the field, with increasing viscosity, fluid loss, flow regulation, gel, diversion, profile control and other functions 



 . At present, China has entered the post-oil mining, to enhance oil recovery, the key to promote polymer flooding and ASP flooding technology 



 Surgery. Through the injection of polyacrylamide solution, to improve the water flow rate ratio, so that mining in the extraction of crude oil content increased. At present, foreign polyacrylamide 



 The application of small fields, due to special geological conditions in China, Daqing Oil Field and Shengli Oil Field has already begun extensive use of polymer flooding technology 



 Surgery. 
 3 paper field 
 Polyacrylamide is widely used in the paper area resident agent, filter aid, are degrees agent. Its role is to improve the paper quality, increase 



 Slurry dewatering performance, increase fines and filler retention, reduce raw material consumption and environmental pollution. Polyacrylamide 



 The effect of the use of paper depends on its molecular weight, ionic nature, ionic strength and activity of other copolymers. Non-ionic polyacrylamide 



 Amines are mainly used to improve the filter paper pulp, and increase dry paper strength and improve the fiber and filler retention; anionic copolymer is mainly used for paper 



 Enhancer and the presence of wet and dry agent; cationic copolymer is mainly used to help filter wastewater treatment and paper making role, the other packing for improving retention 



 Rates also have better results. In addition, PAM is also used in paper making wastewater treatment and fiber recovery. 
 4 textile printing and dyeing industry 
 In the textile industry, as the fabric polyacrylamide sizing agent after the treatment, finishing agent, can generate supple, wrinkle-free, mold-resistant protective layer 



 . Use of its strong hygroscopic characteristics, can reduce the time of spinning yarn break rate; after polyacrylamide as the fabric treatment agent to prevent static electricity and 



 Flame retardant; used as auxiliaries, the product can be attached to the fastness of polyacrylamide big, bright and high, but also as a bleach stable non-silicon polymer 



 Doses; Moreover, polyacrylamide can be used for purification of textile wastewater. 
 5 Other areas 
 In mining, coal washing areas, the use of polyacrylamide flocculants can promote as mining, coal washing water, solids recovery settlement, the water clear, with 



 Useful when the solids recycled to avoid environmental pollution; in the sugar industry, PAM can speed up the juice in the next fine particles 



 Shen, to promote filtering and improve clarity of filtrate; in the culture industry, PAM can improve water quality, increased water and light level, which 



 Improve water photosynthesis; in the pharmaceutical industry, separation of antibiotics used polyacrylamide flocculant, the excipient used as a tablet binder to 



 And process water clarification agent; in the building materials industry, polyacrylamide thickening dispersant can be used as paint, sheet rock saw coolant and ceramic bonding 



 Agent; in agriculture, polyacrylamide can be used as absorbent material and the soil seed culture moisturizer agent. In the construction industry, 



 PAM can enhance the hardness of gypsum cement, asbestos cement to accelerate the dehydration rate. In addition, PAM also be used as natural or close 



 Into the leather of the protective coating and inorganic fertilizer granulation additives.
