you can through a small test to determine the best model, and the optimal dosage of the product. 2, the product prepared as 0.1% (mean solid content) concentration of aqueous solution of neutral salt to the water not suitable. 3, dissolved in water, it will even be thrown into the mix this product in water, appropriate heating (<60 ℃ ) can accelerate into a solution. 4, the solid product with polypropylene woven bag lined with plastic bag, 25kg , colloid plastic drum lined with plastic bag, barrel, 50kg or 200kg . 5, the products are hygroscopic, should be sealed and stored in a cool dry place, the temperature is lower than 35 ℃ . 6, the solid product to avoid the spread on the ground to prevent moisture absorption after the product to become slippery. 7, the preparation of PAM aqueous solution should be in the enamel, galvanized, aluminum or plastic drums for, not in the preparation and storage of iron within the container 8, dissolved, should pay attention to the product evenly and slowly added with stirring and heating measures dissolver, solid knot should be avoided, the solution prepared in the appropriate temperature, and should avoid prolonged drastic mechanical shear is recommended agitator 60-200 turn / min, otherwise it will lead to polymer degradation, affect the results . 9, PAM aqueous solution should be done now with the existing, when dissolved in liquid for a long time to place, its performance will depend on the circumstances of decreased water quality 10, adding flocculant in the suspension solution, if heated long to stir, it will undermine the already formed floc physicochemical properties of polyacrylamide
