 The following is a specific description of the polyacrylamide. 

 Polyacrylamide (PAM): anionic, cationic, nonionic, zwitterionic polymers, used to improve the water treatment process in the settlement, Cheng 
 Clear, filtration, centrifugation process efficiency. 

 Cationic polyacrylamide (PAM) 
 Product Form 
 White powder particles. 
 Features 
 The cationic polymer flocculant is a water-soluble linear polymers, the molecular weight between 600-1200. Cationic PAM showed acidic or alkaline medium cationic, so that effective pollution 
 Sewage water of suspended particles with anionic flocculation and sedimentation. 

 Main purposes: 
 1, the sewage treatment 
 In the use of aluminum salts, iron salts such as inorganic coagulants, flocculants, sewage treatment systems, such as the amount of water need to be addressed over the clarifier 
 Processing capacity or due to other factors that cause water flocs too late settlement of the outer drift, just add the 0.1-0.2ppm PAM coagulant can significantly mention 
 High sedimentation effects. Moreover, the treated water of COD and chroma indicators have significantly improved. Need to mind is the use of inorganic coagulants and flocculation 
 Agent with this product a good adaptation. 
 2, sludge thickening 
 Using 0.3-2ppm can reduce the proportion of chemical, biological, and sludge pool concentrated pool of sludge and water, improve the biochemical pool and the utilization of the sludge thickener 
 . Sludge concentration can be increased by 3-10g / L to 30-100g / L, significantly reduces the volume of sludge Next sludge dewatering process and improve the sewage 
 Mud dewatering equipment and personnel efficiency. 
 3, the sludge dewatering 
 Various concentrated sludge to use PAM for dehydration dry. PAM Fortunately, and dosage as well as dehydration cake dry the sludge dewatering process 
 Dry degrees depending on the different types of sludge is therefore subject to a variety of different types of PAM product testing and selection of anionic polyacrylamide (PAM) 
 Anionic polyacrylamide flocculant, is mainly used for processing based on inorganic solid neutral suspension. In urban and industrial wastewater treatment, with 
 To improve wastewater, suspended solids, COD and phosphate removal. In the primary wastewater sedimentation tank into the 0.25mg / L hydrolyzed polyacrylamide, 
 Suspended solids and COD removal efficiency can be increased to 66% and 23%; 0.3mg / L anionic flocculant sedimentation tank in the secondary wastewater treatment, 
 Suspended solids and BOD removal efficiency can be increased to 87% and 91%, and phosphorus removal from 35% to 91% in the drinking water and life 
 Wastewater treatment for the clarification of surface water, rinse waste water clarification and filtrate adjustment process. In the mining for coal washing water clarification and flotation tailings 
 Filtration of fine coal, tailings (residue), dehydration, clarify the flotation tailings, concentrate thickening and filtration, the hot solution of potash and flotation processing fluid clarification, suddenly re-fluorite 
 Spar of the flotation tailings clarification, the original brine for salt processing, clarification and the recovery of the phosphate mines water treatment sludge dewatering. In steel mills and 
 Metal manufacturing industry, for open-hearth gas wash coated water purification powder metallurgy plants and pickling plant wastewater clarification, electrolyte purification and electroplating waste 
 Clarification. 
 Product Overview 
 The product with alkali before the acrylamide homopolymer total hydrolysis process, granulation, drying, crushing, product appearance was a small white granules or powder 
 At the end like solid anionic polyacrylamide 
 Mainly used as flocculants: suspended particles, coarse, high concentrations of particles with positive charge, sewage water, PH value is neutral or alkaline, due to 
 Anionic polyacrylamide molecular chain containing the polarity function of a certain amount of adsorption of suspended solid particles, the particles bridging the formation of large flocs. Therefore 
 It accelerates the suspended particles in the liquid deposition, have a very clear clarification back to the fast solution to promote the effect of filtering. The products are used in chemical industrial wastewater, 
 Waste water treatment, municipal sewage treatment. Industrial water, high turbidity of the water purification, Shen Qing, coal washing, ore dressing, metallurgy, iron and steel industry, zinc, aluminum 
 Canadian industry, electronic industry and water treatment. 
 2, used in textile sizing agent, the stability of the slurry performance, less off the pulp, fabric breakage rate is low, clean cloth. 
 3 for the oil industry, oil, drilling mud and waste mud treatment, to prevent water channeling, reducing friction and enhanced oil recovery, EOR 
 To extensive use. 
 4, for the paper industry, fillers, pigments, etc. One is to increase retention rates. To reduce the loss of raw materials and environmental pollution; second is to improve 
 The strength of the paper (including dry strength and wet strength), In addition, the use of PAM can also improve the paper tear resistant and porous, to improve the visual and print 
 Performance, but also for the wrapping of food and tea. 

 Non-ion polyacrylamide 



 The non-ionic polyacrylamide homopolymer made with acrylamide. High purity, good solubility, high molecular weight range of PH 1-8. 

 Main purposes: 
 A main sewage treatment, sewage acidic, this series of products are fit. Inorganic flocculant aluminum, aluminum sulfate with make 
 With. 
 For metallurgical beneficiation, such as the selection of Mn ore, copper ore flotation, about 2ppM. Agglutination in the composition of bauxite also be using this amount of 15 p 
 pM. 
 3, textile and chemical fiber paddles, such as PAM-NSG-1, together with some other chemicals used in the textile on the paddle, can increase the permeability and product 
 Anti-static, or directly for pastes. 
 4 in conjunction with bentonite, sand fixing agent can be used for soil water. Hillside planting trees, sand, sand fixation dust, very effective. 
 5, this product in conjunction with wood fiber, can be used for oil field profile control plugging agent. 

 Zwitterion polyacrylamide 

 Zwitterionic appearance of white powder, effective PH range 1-14, according to the different uses are divided into two processes: one is from acrylamide, acrylic acid, Yang 
 Ionic monomer is made; Another modification made by the non-ionic polyacrylamide. Its product molecular structure, both cation and anionic 
 Son, salinity, temperature resistance, better. 

 Main purposes: 
 1, oil field profile control blocking agent, crosslinking agent, stabilizer, coagulant, generate important polymeric gel and resin gel 
 Strong coagulant glue blocking agent. By-laws role as physical blockage plug the formation pores and cracks, scaling, and can control the gel time to adapt to 
 Different geological clear conditions. 
 2 kinds of oil, organic, inorganic, sewage, complex sewage treatment. PH changing the sewage system, a single ion polypropylene 
 The Amide use effect is far less than the synergistic effect of the zwitterionic, cationic polyacrylamide and anionic polyacrylamide used in conjunction with 
 Will react to produce precipitation. Zwitterionic products are most satisfactory. 
 For sludge dewatering. 
 4 for paper chemicals
