Umsebenzi ophambili kunye neempawu zesakhiwo:
Ngaphantsi kwesenzo sokufudumeza komoya oshushu kunye ne-convection kwicandelo le-oven, ifilimu yokwahlula iguqula i-CH₂Cl₂ phezu komhlaba, apho inxalenye yegesi yegesi igxininiswe ibe yi-liquid, inxalenye yegesi yomsila ongagungqiyo isetyenziselwa ukujikeleza igesi yokomisa, kunye negesi eyomileyo. enye inxalenye ikhutshwa kwinkqubo yokubuyisela igesi yomsila. Sikhetha iqokobhe lekhokhonathi elenziwe ngokwezifiso ezenziwe ngekhabhoni, enezibonelelo ze-CH₂Cl₂ umthamo we-adsorption enkulu, ukusebenza kakuhle kokucoca kunye ne-hydrophobicity elungileyo. Ngendlela yetanki ye-adsorption ene-horizontal, umthamo wokulayishwa kwekhabhoni mkhulu, ukuguquguquka kokusebenza kuphezulu, ukuxinwa kwegesi yomsila we-CH₂Cl₂ ingaphantsi kwe-20mg / m³, kwaye izinga lokubuyisela lingaphezulu kwe-99.97%.
