The difference between anions and cations of polyacrylamide
There are significant differences between the anions and cations of polyacrylamide in terms of appearance, molecular weight, price, use, etc. First of all, from the appearance, both anionic and cationic polyacrylamide have white particles and emulsions. The white granular anionic and cationic polyacrylamide are almost indistinguishable in appearance, but the emulsions are different. Anionic emulsions are white, while cationic emulsions have a light blue color. In terms of molecular weight, anions range from 4 million to 25 million, while cations range from 7 million to 12 million. In terms of price, anionic polyacrylamide is usually cheaper than cationic polyacrylamide, and the higher the molecular weight, the higher the price. In terms of main indicators, the main indicators of anionic polyacrylamide include molecular weight and degree of hydrolysis, while the main indicators of cationic polyacrylamide are ionicity and molecular weight. In terms of use, anionic polyacrylamide is mainly used to treat inorganic wastewater, chemical wastewater, petroleum industry, textile sizing agent, papermaking industry and as an adhesive, etc. Cationic polyacrylamide is often used to treat organic wastewater such as food factory wastewater, slaughterhouse wastewater, monosodium glutamate factory wastewater, etc., and is used for sludge dehydration.
