In the production process of liquid crystal panel, it is necessary to use photoresist to bond the panel. After bonding, solvents need to be used to flush the faceplate, and the solvent in the rinse contains photoresist. So it is necessary to recycle and reuse through solvent distillation.
Thin-film evaporator combined with distillation tower process, the solvent recovery rate of the stripping liquid can reach more than 90%.
Equipped with special film evaporator, the glue is avoided to condensed on the inner surface of the evaporator after solvent removal
