How to remove the solvent in the synthesis of water-based polyurethanes using the solvent method
Thread Content
I work in the production of water-based polyurethanes and am facing difficulties in removing solvents; I would appreciate some help. 1. Since it is a small-scale enterprise without a distillation tower, a removal tank is used instead to remove the solvent. 2. How can the removal efficiency be improved? 3. How to ensure solvent recovery and reduce VOC emissions? Please help to exchange and share experiences. Thank you! Thank you! Thank you!
Vacuuming can improve efficiency; by not accounting for the solvent that does not react, an approximate recovery rate can be determined
