People who have a certain understanding of cationic polyacrylamide generally pay close attention to two indicators when purchasing cationic polyacrylamide, one is the ionic degree of cationic polyacrylamide, and the other is the molecular weight of cationic polyacrylamide. These two factors directly determine the use effect of cationic polyacrylamide.

In practice, because of the production process, most of the cationic polyacrylamide will be fixed at a certain molecular weight value, and then produce cationic polyacrylamide with different ionic degrees. However, it is not means that the molecular weight of cationic polyacrylamide can not be changed. In most cases, the production process will be adjusted according to the needs of customers, and the cationic polyacrylamide with appropriate molecular weight will be produced. There is a certain relationship between the molecular weight and ionic degree of cationic polyacrylamide. The larger the molecular weight of cationic polyacrylamide is, the smaller the ionic degree will be.

Generally speaking, the molecular weight of polyacrylamide can be between 500000 and 1200000. When the molecular weight of polyacrylamide with low molecular weight is used, the flocculant is small, or the flocculation effect can not be achieved directly, while the ionic degree of cationic polyacrylamide with high molecular weight is very low, The precipitate formed by cationic polyacrylamide with low ionic degree is not compact enough to achieve good effect. Therefore, the selection of ionic degree of cationic polyacrylamide is also an important factor in purchase.

The ionic degree and molecular weight of cationic polyacrylamide directly determine the price when it is purchased. Therefore, we need to choose the product according to the actual production and use.
