kraft paper was impregnated in mineral oil at different temperatures and duration. my project is to get the DP value at different duration. in order to be measured by viscometer, the sample must be dried and dissolve. so, whats is the method to dry the paper that has been impregnated in oil? water? degreased with hexane?
Thanks.
Dear Nurul izzati Hashim, if I understood well the question, what is the polymeric binder of such a paper ? Is polyacrylamide ? Anyway, whatever the situation is, the polymer is to be extracted, purified, and tested by viscometry as a function of oil-immersion time. My Regards
I used kenaf pulp to make a paper. I want to see the DP value drop from a new to aged paper.
Dear Nurul izzati Hashim, so it is a natural cellulose. I think my previous answer still hold. The following link provides a good document with the references included. My Regards
