Difference of different molecular weights of anionic polyacrylamide

Whenever customers inquire about the price of anionic polyacrylamide, our quotations vary greatly, ranging from thousands to more than 10,000. Customers who know polyacrylamide will know that the price is different because the hungry molecular weight of polyacrylamide is different, and only know that the price with good quality is definitely high, but it is not suitable for you with high molecular weight, and the low molecular weight is not suitable for you, depending on what kind of sewage is used. Even the polyacrylamide with the same ionic property has different molecular weights, and there are great differences in application!

Molecular weight refers to the length of molecular chain in the molecule. The higher the molecular weight, the longer the molecular chain, the greater the viscosity of polyacrylamide solution and the greater the resistance in the solution. The higher the molecular weight, the better the product effect. It is necessary to combine the sludge dewatering equipment and the source, characteristics, composition and proportion of sludge. For example, if the molecular weight is too high, the filter cloth may be blocked, which will affect the dewatering effect; Another example is the centrifuge, which requires the floc to be stable and not broken under the shearing action, so the product with relatively high molecular weight should be selected.

In general, Super molecular weight polyacrylamide is mainly used for tertiary oil recovery in oil fields, while high molecular weight PAM is suitable for flocculant, medium molecular weight products are mainly used as paper dry strength agent, and low molecular weight PAM is mainly used as dispersant!
