Detailed Product Description: | Polyacrylamide mesh: mesh refers to material granularity or coarseness, mesh number per unit area on the number of squares. Generally is defined on 1 inch by 1 inch within the area of ??the number of mesh number, the number of screen mesh. If 600 mesh per square inch square 600 mesh, 20 mesh polyacrylamide mesh to 80 mesh, which is between 0.85mm ~ 0.2mm, which is a particulate mesh size of polyacrylamide, powder Polyacrylamide mesh size can be controlled at about 100 mesh, mesh the greater the more readily soluble polyacrylamide, polyacrylamide alone mesh size of the product is good or bad can not be measured! Toxicity: polyacrylamide and water disintegration itself is not toxic, polyacrylamide, from the residual toxicity of acrylamide (AM). Acrylamide is caused by nerve agents, there is damage to the nervous system, poisoning of the body after the table weakness, ataxia and other symptoms. Therefore, provisions of national health departments have industrial products polyacrylamide residual acrylamide content, typically 0.05% -0.5%. Polyacrylamide for industrial and urban sewage purification treatment, generally allowing 0.2% acrylamide levels for direct drinking water treatment, the levels of acrylamide to be below 0.05%. Cationic polyacrylamide CPAM sludge dewatering special presentation: white powder or granular, ionic degree from 10% to 80% water soluble, can be dissolved in water in any proportion and insoluble in organic solvents. CPAM was high polymer electrolyte characteristics for negative charge and organic-rich wastewater treatment. Product description: cationic polyacrylamide CPAM is linear polymers, 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, etc., suitable for dyeing, paper making, food, construction, metallurgy, mineral processing, coal, oil, aquatic products processing and fermentation of organic colloid content industries higher wastewater treatment, especially for urban sewage, sludge, paper sludge and other industrial sludge dewatering. ※ English name: cationicpolyacrylamides, referred CPAM ※ Appearance: white powder or granular ※ solid content: ≥ 90% ※ ※ Weight :800-12000000 Water insoluble: ≤ 0.5% ※ Residual Unit: ≤ 0.05% ※ cationicity :10-90% ※ dissolution time: ≤ 60 min Features: 1, good water solubility in cold water can be completely dissolved. 2, add a small amount of cationic polyacrylamide, you can get a great flocculation. Generally add 0.01 ~ 10ppm (0.01 ~ 10g/m3), to be fully effective. 3, while using cationic polyacrylamide and inorganic flocculants (ferric sulfate, aluminum chloride, etc.), can show a greater effect. 1) for sludge dewatering sludge properties can be selected according to the respective grades CPAM product can effectively enter in the sludge filter press sludge dewatering prior to dehydration, the resulting floc large, non-stick cloth, filter press is not scattered, flow thick mud cake, dehydration, high efficiency, cake moisture content below 80%. 2) for domestic sewage and organic wastewater treatment, cationic polyacrylamide products with acidic or alkaline medium showed a cationic, so that the effluent suspended particles with a negative charge wastewater flocculation, clarification is very effective. Grain alcohol such as production waste, paper waste, urban sewage treatment plant effluent, wastewater, wastewater monosodium glutamate, sugar water, high organic content wastewater, wastewater feed, textile printing and dyeing wastewater with cationic polyacrylamide than with anionic, non-ionic polyacrylamide or inorganic salts effect several times or several times higher, because such waste generally negative charge. 3) is used to river water for tap water treatment flocculant, with less effect, low cost, especially with the use of better composite inorganic coagulant, it will become rule the Yangtze River, Yellow River and other water basins plant flocculant. Cationic polyacrylamide to use: 1, through a small test to determine the best model, and the optimal dosage of the product. 2, the product formulated as a 0.2% (mean solid content) concentration in an aqueous solution of a neutral salt to the water is not appropriate. 3, dissolved in water, mixing the product even thrown into water, the appropriate heating (<60 ℃) can accelerate into a solution (mixing time of 40 minutes). 4, the solid product with a paper bag lined with plastic bag, 25kg. 5, the product is hygroscopic and should be sealed and stored in a cool dry place, the temperature is lower than 35 ℃. 6, the solid product to avoid scattered on the ground, to prevent the product after moisture absorption and the earth becomes slippery. 7, the preparation of PAM solution should be in the enamel, zinc, aluminum or plastic bins for non-iron containers in preparation and storage. 8, dissolved, should pay attention to the product evenly and slowly added with stirring and heating measures dissolver, should avoid knot solid solution prepared at a suitable temperature, and should avoid prolonged drastic mechanical shear. Recommend stirrer 60-200 rpm / min, otherwise it will lead to degradation of the polymer, affect the results. 9, PAM solution should be done using now, when the lysate place a long time, and its performance will be the case as the water gradually decreased. 10, at home against suspension Tim flocculant solution, if prolonged stirring fierce, it will destroy the already formed flocs.
