Polyacrylamide polyacrylamide cationic polyacrylamide anionic polyacrylamide nonionic polyacrylamide flocculant a purifying agent, polyacrylamide as a retention aid in the papermaking process, a reinforcing agent. 2, polyacrylamide as coagulant in water treatment, flocculants, sludge dewatering. 3, as the precipitation agent in oil drilling, oil-displacing agent. 4, PAM is also widely used in terms of thickening, colloid stability, drag reduction, adhesion, film formation, biomedical materials and the like. Polyacrylamide using the methods and precautions: 1, through a small test to determine the best model, and the optimal dosage of the product. 2, the product formulated into 0.1% (mean solid content) solution concentration to the neutral salt-water is appropriate. 3, when dissolved in water, the product even thrown into stirred water, proper heating (<60 ℃) can accelerate into a solution. 4, solid products with polypropylene woven bag lined with plastic bag, 25kg, jelly plastic drum lined with plastic bag, 50kg per barrel or 200kg. 5, this product is hygroscopic and should be stored in a cool dry place, the temperature is lower than 35 ℃. 6, solid products avoid scattered on the ground to prevent moisture absorption after the product becomes so slippery. 7, PAM PAM aqueous solution formulation should be enamel, galvanized, aluminum or plastic drums were allowed preparation and storage. 8 in the iron vessel, polyacrylamide dissolved, should pay attention to a uniform product slowly added with stirring and heating measures dissolver, avoid hardening of the solution at a suitable temperature preparation, and should avoid prolonged drastic mechanical shear recommended blender 60-200 turn / min, otherwise it will lead to polymerization degradation, affect the results .9, PAM solution should be done using now, when the situation lysate place a long time, depending on the quality of their performance will gradually decrease. 10, polyacrylamide manufacturers introduced against suspension floc anionic polyacrylamide (APAM) Product description home after Tim flocculant solution, stirring vigorously if prolonged, it will undermine the already formed: anionic polyacrylamide (APAM) appearance of white powder, molecular weight from 600 10000-25000000 water soluble, can be dissolved in water in any proportion and insoluble in organic solvents. Effective PH value in the range of 7-14, in a neutral alkaline medium showed the characteristics of high-polymer electrolyte, the electrolyte salt sensitive, with high metal ion can be cross-linked into an insoluble gel. Anionic polyacrylamide (APAM) Features: 1) flocculation: PAM allows suspended material by charge neutralization, bridging adsorption, since flocculation. 2) Adhesion: effect by mechanical, physical, chemical, from the adhesion. 3) drop resistance: PAM can effectively reduce fluid friction, water with traces of PAM can drop resistance 50-80%. 4) thickening: PAM under neutral and acidic conditions are thickening effect, when the PH value above 10 PAM easy hydrolysis, semi-mesh structure, thickening more obvious. Anionic polyacrylamide (APAM) main purposes: Industrial waste water treatment polyacrylamide: For suspended particles, representing a high concentration of particles with a positive charge, water PH value is neutral or alkaline water, iron and steel plant wastewater, electroplating plant wastewater, wastewater metallurgy, coal washing waste water sewage treatment works best. Drinking water treatment: a lot of water from the river water plant, sediment and mineral content is high, more turbid, though filtered through the precipitate, still can not meet the requirements, needs adding flocculants, inorganic coagulant dosage is 1 / 50, but the effect is several times the inorganic flocculants, for serious organic pollution of the river water can be inorganic coagulant and the company with the use of polyacrylamide better. Loss of starch lees recovery and alcohol plant starch factory: Many starch factory wastewater containing a lot of starch, is now adding anionic polyacrylamide, starch particle coagulation and sedimentation, and then the precipitate was filter into the filter press cake like, can be used for feed, ethanol plants may be used alcohol anionic polyacrylamide dehydration, pressure filtration for recycling. Settlement for the river mud. Dry strength agents for paper.
