Polyacrylamide Applications: (PAM application strong) 1, as retention aids in papermaking process, a reinforcing agent. 2, as the coagulant in water treatment, flocculants, sludge dewatering agent. 3, as the precipitation agent in oil drilling, oil displacement agent. 4, PAM also widely used in terms of thickening, stabilizing colloid, 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 models and the best dosage of the product. 2, the product formulated as a 0.1% (of solid content) aqueous solution of concentration, to salt-neutral 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 product with PP 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 sealed in a cool dry place, the temperature is lower than 35 ℃. 6, the solid product to avoid scattered on the ground, to prevent moisture absorption after the product becomes so slippery. 7, the preparation of PAM solution should be in enamel, galvanized, aluminum or plastic bins were not formulated and stored in iron containers 8, when dissolved, should pay attention to the product evenly slowly added with stirring and heating dissolver measures, avoid knot solid solution at the appropriate temperature preparation, and should avoid prolonged drastic mechanical shear recommended blender 60-200 turn / min, otherwise it will lead to degradation of the polymer, affect the results . 9, PAM solution should be done now with the existing, long period of time when the dissolved solution, its performance will be subject to availability and decreased water quality. 10, after the family of the suspension Tim flocculant solution, if a long and intense then stirring performed, will destroy the flocs already formed
