Help – Regarding polyacrylamide
Thread Content
I want to use polyacrylamide to increase the viscosity of water, but I don’t know how much to add. I currently have polyacrylamide with a molecular weight of 8 million. I was wondering if anyone who has used polyacrylamide before could send me a curve showing how the viscosity of the polyacrylamide solution changes as the amount of polyacrylamide added increases. I would be extremely grateful. Polyacrylamide with other molecular weights will also work; I don’t have a viscometer here to measure the viscosity. I would be very grateful if any kind person passing by could help.
Just having the molecular weight isn’t enough; ionicity is also important. It’s unlikely that many people will have this table, as no one does this work unless they are preparing a paper. Moreover, the properties of products from different manufacturers vary greatly, so it’s not very useful to create viscosity curves. I hope the original poster will engage more in discussions on forums.
