What are the storage time requirements for liquid and solid polyacrylamide?

2023-04-29
Water treatment manufacturers will teach you how to better store polyacrylamide, liquid and solid flocs during storage. Polyacrylamide is a kind of white particle polymer with good water solubility. Because its molecular chain contains a certain amount of positive and negative, neutral charge and strong adsorption genes, it acts as the charge on the surface of suspended colloidal particles in the treated water, which damages its stability. The unstable colloidal particles adsorbed with each other under the action of polymer active genes and rapidly formed large floc sedimentation. So as to play the ultimate purpose of solid-liquid separation.

Polyacrylamide storage Common sense: Normally, it exists as a solid particle, but when polyacrylamide is configured as a solution, it exists as a liquid. In fact, solid-state storage lasts longer, more than two years; But the diluted liquid shelf life is very short, generally not more than a week, but also a day of use cycle, especially cationic polyacrylamide, its use cycle is shorter, that is, 24 hours. Therefore, for liquid polyacrylamide, configure as much as possible to prevent waste.
