What is the degree of hydrolysis and ionic degree of polyacrylamide?

 

 

PAM polyacrylamide polymer flocculant has been widely used by the masses of customers, but they may be some basic characteristics of this product is not understanding, its main technical indicators such as molecular weight and degree of ion and the degree of hydrolysis, the degree of ion is the main technical index of the cationic polyacrylamide, degree of hydrolysis is one of the important technical indicators, anionic and non-ionic These two different indicators directly determine the effect of the reaction with sewage, so many people will ask, what is the degree of hydrolysis and ionic degree, today for you to explain the degree of hydrolysis and ionic degree of PAM.

 

Definition of degree of hydrolysis:

Polyacrylamide dissolved hydrolysis degree is mainly refers to the product of hydrolysis occurring after the ratio of the total number of molecules and molecules dissolved, its degree of hydrolysis is mainly in the production of polymerization time by the amount of sodium carbonate was added to control, sewage treatment the degree of hydrolysis of the amide is more commonly used in products, control the degree of hydrolysis between 20-25%.

 

Definition of ionic degree:

Ion of polyacrylamide is mainly refers to the density of the electrically charged particles, the electric charge density determines its reaction during sewage treatment effect, its degree of ion is mainly in the production of add cationic polymerization monomer to control, sewage treatment using cationic ions is generally 10 to 60, the higher the degree of ion containing cationic monomer amount is, the greater the Therefore, the price of cation is directly related to the ionic degree, the higher the ionic degree, the higher the price will be.

There are a lot of customers will have an error, it is thought that the higher the molecular weight, the higher the degree of ion use effect will be better, today for you to correct the wrong idea, why say so, because in the life each kind of water quality is not the same, including the characteristics and composition, and so on, nature of the water quality of different industry is different also, Therefore, the choice of the type of flocculant will be different, we should be based on the actual situation, through small trial to select, repeated test and analysis, and then pilot and large trial, to determine the more suitable flocculant type number and dosage.
