Polyacrylamide ion degree generally refers to cationic polyacrylamide. Ionity and molecular weight are two major indicators to measure the quality of cationic polyacrylamide. Molecular weight refers to the length of the polyacrylamide molecular chain, and ionicity refers to the density of charges, that is, the number of charges carried by polyacrylamide. The ionicity of polyacrylamide affects the tightness of its flocs, which is closely related to the treatment effect. Generally, the higher the ion degree and molecular weight of cationic polyacrylamide, the better the quality and the higher the price. But it does not mean that the greater the ion degree and the greater the molecular weight, the better the treatment effect, Is the polyacrylamide with high ionicity good?

The ion degree of cationic polyacrylamide is a very important indicator. The higher the ion degree, the denser and larger the impurity flocs formed in sewage treatment. Cation is mainly used in industrial sewage and municipal sewage with negative charge. When in use, cationic polyacrylamide is dissolved in a proportion of one thousandth and added to the sewage. Subsequently, it has an effect, and the impurities in the encapsulated sewage form a connected precipitation effect, which is usually said-sludge dewatering. After being added to sewage, it quickly reacts with impurities, so that water and impurities separate and precipitate. Then it can be put into the mud pressing equipment.

Polyacrylamide molecular weight: refers to the length of the molecular chain. A large molecular weight does not mean good performance, and a small molecular weight does not mean poor performance. It mainly depends on the purpose. If it is used for desliming in the sewage treatment field, it must be combined. Desliming equipment and sludge properties, if it is used in a traditional crawler filter press, a high molecular weight may cause clogging of the filter cloth, poor dehydration and other problems, which will affect the dewatering effect; if it is used in a centrifugal desilter, because of its The working principle is different, the molecular weight is required to be higher, and the produced flocs must be able to withstand shear as much as possible. It can also be understood that the flocs must be strong enough, so choose a product with a higher molecular weight. Polyacrylamide ion degree: refers to the cationic charge density of cationic polyacrylamide. The ion degree of products circulating on the market is generally 20% to 50%. The larger the ion degree, the smaller the molecular weight. It also determines the product price and the ion degree It determines the tightness of the flocs, moisture content and other issues, but in the selection, it is still necessary to select through experiments, from small laboratory trials to computer amplification tests, and sometimes it is necessary to repeat trials until the best agent is determined.

From the above detailed description, Is the polyacrylamide with high ionicity good? it can be seen that polyacrylamide does not have the higher the ion degree, the better the effect, and the polyacrylamide ion degree used by different industries and different water quality is also different. Polyacrylamide ion degree: refers to the cationic charge density of cationic polyacrylamide. The ion degree of products circulating on the market is generally 20%-50%. The larger the ion degree, the smaller the molecular weight. It also determines the product price and the ion degree It determines the tightness of the flocs, moisture content and other issues, but when selecting polyacrylamide products, it is still necessary to select the type through experiment, and then test on the machine to determine the optimal dosage.
