Polyacrylamide as a commonly used water purification agent, its molecular weight has three standards: low, medium and high. Generally speaking, the molecular weight and the viscosity of Polyacrylamide have a great relationship, many people think that the higher molecular weight does not mean that thePolyacrylamide is better, about this question YuXinHuan chemical industry to give you a detailed explanation.

1. The higher the molecular weight, the better the conclusion is actually incorrect, we are in the selection of Polyacrylamide, generally need to be tested, and in the actual application needs to be based on the industry, water quality, equipment, etc. to determine the size of the appropriate molecular weight.

2. As far as we know, there are no less than 100 types of Polyacrylamide, so we can choose the suitable type of Polyacrylamide according to the type and range of sewage to be treated, because there is no one type of polyacrylamide that can solve the type of sewage used, so it is necessary to determine the suitable molecular weight of the Polyacrylamide through the small area experiment beforehand, which can make the treatment of the lower cost and the effect is better.

3. Generally speaking, the higher molecular weight of Polyacrylamide represents its own better viscosity. When we are adding or experimenting, not the higher molecular weight is the best, so we need to pay attention to the reasonable and correct selection of Polyacrylamide models and specifications.

Comprehensive analysis of the above can be concluded that: sewage treatment, not the higher the molecular weight of Polyacrylamide, the better the effect. Different molecular weight range, the effect of sewage treatment has a world of difference. If you insist on choosing Polyacrylamide with high molecular weight, it may be counterproductive.
