Polyacrylamide dosing method and matters needing attention

① Through small test, determine the appropriate model, and the appropriate amount of the product.

The product is prepared into a 0.1%(refers to the solid content) concentration of aqueous solution, with neutral water without salt is appropriate.

When dissolving water, the product is evenly sprinkled into the stirred water, and the appropriate heating (<60 ℃) can be accelerated into a solution.

④ Solid products shall be packed in polypropylene woven bags lined with plastic bags of 25kg each, and gelatinous products shall be packed in plastic barrels lined with plastic bags of 50kg or 200kg each.

⑤ This product is hygroscopic and should be sealed and stored in a cool and dry place at a temperature lower than 35 ℃.

The solid product to avoid sprinkling on the ground, in order to prevent the product after absorbing moisture to become slippery.

⑦ When preparing PAM aqueous solution, it should be carried out in enamel, galvanized, aluminum or plastic barrels, and cannot be prepared and stored in iron containers.

⑧ When dissolving, attention should be paid to adding the product evenly and slowly into the dissolver with stirring and heating measures. Solubility should be avoided. The solution should be prepared at an appropriate temperature and mechanical shearing for a long time should be avoided. It is recommended that the agitator 60-200 rpm, otherwise it will cause polymer degradation and affect the use effect.

Pet-name ruby PAM aqueous solution should be ready for use. When the dissolved solution is placed for a long time, its performance will gradually decrease depending on the water quality.

After the aqueous flocculant solution is added to the suspension, if it is vigorously stirred for a long time, the flocs that have already formed will be destroyed.
