Use of polyacrylamide methods and precautions
1, through a small test to determine the best model, as well as the optimum amount of product. 2, the product formulated as a 0.1% (of solid content) aqueous solution of concentration, to salt-neutral water is appropriate. 3, was dissolved when water, the product uniformly thrown into stirred water, proper heating ((60 ℃) can accelerate into a solution. 4, solid product with polypropylene woven bag lined with plastic bag, 25kg, with jelly plastic drums lined with plastic barrel, 50kg or 200kg. 5, this product is hygroscopic, should be sealed and stored in a cool dry place, the temperature is lower than 35 ℃. 6, the solid product avoid scattered on the ground, to prevent products after the moisture absorption becomes so slippery. 7, the preparation of PAM solution should be enamel, zinc, aluminum or plastic bucket carried non-preparation and storage. 8 in the iron vessel, when dissolved, should pay attention to the product evenly slowly added with stirring and heating measures dissolver should avoid knot solid solution at a suitable temperature preparation, and should avoid prolonged drastic mechanical shear recommendation blender 60-200 turn / min, otherwise it will resulting in degradation of the polymer, affect the results. 9, PAM solution should be done now with the existing, dissolved when the case was placed a long time, depending on the quality of their performance will be gradually reduced. 10, the flocculant is added to the suspension after the aqueous solution, if prolonged vehemently agitated, it will destroy already formed flocs.
