Polyacrylamide flocculant is an organic high polymer, molecular weight is high, the dissolution method and the general inorganic flocculant is very different:

1. Powder polyacrylamide should not be used directly, before use should be dubbed a certain concentration of aqueous solution to ensure the use of results

2. With the temperature of the water can be dissolved polyacrylamide can be increased to raise the temperature can be slightly promoted to dissolve, but the water temperature should not exceed 50 degrees Celsius, the water temperature is too high will produce polyacrylamide thermal degradation, thus affecting its effect

3. Polyacrylamide flocculant concentration is generally one thousandth

4. The prepared flocculant solution should not be transported by centrifugal pump, so as to avoid high-speed rotation of the particles caused by the degradation of the polymer, the preparation of the specific operation is as follows: in the dissolved tank by adding a certain amount of water, weighed a certain amount of polypropylene Amide, start stirring, the water will stir the whirlpool, the dry powder evenly into the water around the whirlpool, should pay attention to avoid dry powder particles into the water after the adhesion of each other. General anionic polyacrylamide, cationic polyacrylamide to be stirred for about an hour, non-ionic need to stir for about two hours, the polymer particles are fully dissolved and become a uniform transparent viscous solution

5. Powder polyacrylamide in a dry, cool place can be stored for more than two years, but dubbed solution should not be stored for too long time.

6. Iron ions are catalysts that cause degradation of polyacrylamide. Therefore, in the preparation, transfer, storage polyacrylamide solution, to avoid the solution and iron ions in contact. The preparation of polyacrylamide solution is preferably made of stainless steel, glass fiber reinforced plastic and other materials.
