Main performance and structure features:
The main components of the extract are CH₂Cl₂, white oil and trace water. taking advantage of the different boiling points of the three substances, the extract is carried out in turn through a series of measures, such as initial distillation, atmospheric distillation, vacuum gas extraction, CH₂Cl₂ and filtration of white oil. the extraction solution was separated and purified to recover CH₂Cl₂ (purity > 99.97%) and white oil (purity > 99.97%) to meet the requirements of reuse in the production line and reduce the material consumption of the production system. Reduce the production cost of the separator film.
