Does the Price of Polyacrylamide Affect the Use Effect?
The price of polyacrylamide varies greatly, ranging from thousands to tens of thousands. What causes the price difference of polyacrylamide? First, the ionic type of polyacrylamide is different. Generally speaking, the price of anion is the lowest, the price of non-ion is higher than that of anion, the price of zwitterion is higher than that of non-ion, and the price of cation is higher than that of the above several ions. This price relationship is determined by production process and cost. As far as anionic polyacrylamide is concerned, its molecular weight ranges from millions to more than 20 million. Different molecular weights lead to different prices. The higher the molecular weight, the higher the price. The ionicity span of cationic polyacrylamide is also very large. The ionicity ranges from 5 to 80 degrees and the price of cations is related to ionicity. The higher the ionicity, the higher the price.
