Polyacrylamide is acrylamide (AM) monomer by free radical initiated polymerization of a water-soluble linear polymer, insoluble in most organic solvents, has good flocculation, can reduce the frictional resistance between the liquids, by ion characteristic points can be divided into non-ionic, anionic, cationic and amphoteric four types. Polyacrylamide mesh: mesh size refers to the thickness of the material or, mesh is the number of squares per unit area generally is defined as the number of cell number in 1 inch by 1 inch in the area of ??that sieve. the number of mesh networks. Such as 600 mesh per square inch 600 square mesh, mesh polyacrylamide 20 mesh to 80 mesh, is between 0.85mm ~ 0.2mm, which is granular polyacrylamide mesh size, powder like polyacrylamide mesh size can be controlled at about 100 mesh, mesh the greater the more readily soluble polyacrylamide, polyacrylamide mesh size alone is unable to measure the quality of the product! CPAM Caution: 1, floc size: floc is too small will affect the drainage rate, floc floc constraints make much more water and reduce the mud biscuits. After selecting the molecular weight polyacrylamide can adjust the size of floc. 2, sludge characteristics. The first point to understand the source of sludge characteristics and composition, proportion. Depending on the nature of the different sludge can be divided into two kinds of organic and inorganic sludge. CPAM for disposal of biosolids, the relative anionic polyacrylamide flocculant for mineral sludge, strong alkaline when cationic polyacrylamide, anionic polyacrylamide and should not be used when very acidic, solid content high amount of sludge is usually polyacrylamide is also large. 3, floc strength: floc under shear should insist on steady without breaking. Advances in molecular weight polyacrylamide or select the appropriate molecular structure to help improve floc stability. 4, the degree of ionic polyacrylamide: for dewatered sludge, flocculant available ions of different small test do first stop through the selection, select the best suitable polyacrylamide flocculant thus being able to obtain the best effect, but also make dosage minimal cost savings. 5, polyacrylamide dissolved: dissolve hair good talents full play flocculation. Sometimes it needs to speed up the dissolution rate, when the concentration of progress can think of polyacrylamide solutions. Polyacrylamide failure can be judged from two aspects, one is the viscosity reduction, two flocculation deteriorates. I. Introduction: polyacrylamide is water-soluble polymers. Because of its molecular chain containing a certain number of polar groups, by adsorption of suspended solid particles cause bridging between the particles or the formation of large flocs by charge neutralization and the particles agglomerate. Therefore, it can accelerate the sedimentation of particles in suspension, there is a very obvious solution to speed up the clarification, to promote filtering and other effects. Second, product characteristics: 1, cationic, anionic, nonionic, amphoteric, variety complete specifications, to meet the various needs. 2, water-soluble, it can be dissolved completely in cold water. 3, add a small amount of this series, you can receive a great flocculation. Usually just add 0.01 - 10 ppm (0.01 - 10g / m3), to be fully effective. 4, while the use of this product and PAC, may show greater effects. Third, the function: This product flocculation effect is very strong, because it has: l, clarify purification; 2, promote settlement; 3, filter promoting effect; 4, thickening (thick) effects and other effects. Waste water, waste water treatment, sludge dewatering, drilling mud additives, mineral processing, coal washing, paper, etc., can fully meet the requirements of various fields. The use of methods: 1, when used, dubbed 0.1 - 0.3% aqueous solution concentration to use neutral salts debris-free water is appropriate. 2, when dissolved, stirring this series even thrown into water, stir speed control in 100-300rpm, proper heating (<60 ℃), can accelerate the dissolution. 3, adjusting the PH value of liquid to be treated, so that the product fully play its role (by selecting the amount of test PH value and the best products in this series). 4, when added to a solution of this series, should accelerate the mixing liquid to be treated, there floc, the stirring speed to slow down in order to facilitate and accelerate the growth of floc settlement.
