Lub evaporator teb yog tsim rau siab viscosity evaporation nyob rau hauv tshuaj thwmsim, thaum iav reactors tsis haum los yog tsis muaj rotary evaporator, feem ntau yog txiav txim los ntawm lub hauv paus ntsiab lus ntawm kev ua hauj lwm thiab tsim lub hom phiaj ntawm ob qho tib si. Lub evaporator teb yog tsim rau cov qauv me me thiab cov khoom tsis haum, nrog cov evaporation siab thiab cov nyhuv concentration. Nws tsim cov yeeb yaj kiab loj loj ntawm lub raj mis phab ntsa los ntawm kev hloov cov tshuaj, ua rau thaj chaw evaporation thiab ua kom cov evaporation nrawm dua. Tsis tas li ntawd, rotary evaporator tuaj yeem ua haujlwm nyob rau hauv qhov tsis zoo siab los ntawm kev txo lub zog siab kom txo qhov kub ntawm qhov kub, yog li ua kom cov evaporation ntawm cov kuab tshuaj sai. Qhov no yog qhov zoo heev rau kev tuav cov viscosity siab, vim tias txo qhov kub ntawm qhov kub tuaj yeem txo qhov viscosity thiab qhov nro ntawm cov tshuaj, ua rau cov txheej txheem evaporation smoother. Cov iav tshuaj tiv thaiv cov hlab ntsha yog tsim rau lub peev xwm loj thiab cov tshuaj lom neeg tsis zoo. Txawm li cas los xij, nws cov txiaj ntsig distillation yuav tsawg thiab tsis haum rau kev daws cov viscosity siab. Kev tsim cov iav tshuaj tiv thaiv cov hlab ntsha feem ntau yog siv rau cov tshuaj lom neeg nyuaj xws li polymerization, hydrolysis, esterification, thiab lwm yam, thaum cov evaporators teb feem ntau yog siv rau kev sib xyaw, purification, thiab hnyav rov ua haujlwm. Yog li ntawd, nyob rau hauv cov txheej txheem evaporation ntawm kev daws cov viscosity siab, rotary evaporators tau dhau los ua kev xaiv zoo dua vim lawv cov kev ua haujlwm siab, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig.

Rau cov kev daws teeb meem siab viscosity, tubular condenser tuaj yeem txo qhov adhesion thiab scaling. Tsis tas li ntawd, cov qauv ntawm tubular condenser yog compact, yooj yim rau installation thiab txij nkawm.
4. Cua txias: Rau cov condensers uas tsis haum rau cov dej txias lossis xav tau cov dej txias ntau, lub tshuab cua txias yog qhov kev xaiv zoo. Nws ua tiav cov txiaj ntsig txias los ntawm ntuj los yog yuam convection ntawm huab cua. Rau cov kev daws teeb meem siab viscosity, lub tshuab cua txias tuaj yeem muab cov txiaj ntsig txias txias, tab sis nws yuav cuam tshuam rau cov nyhuv evaporation vim qhov ua kom sov qis dua.
Sib piv cov kev xaiv condenser, ob qho tib si kheej kheej thiab tubular condensers yog qhov tsim nyog rau kev tuav cov viscosity siab evaporation. Spherical condensers muaj lub siab ua haujlwm zoo thiab txo qhov adhesion thiab scaling, tab sis lawv cov nqi yuav siab dua. Tubular condenser muaj qhov zoo ntawm qhov chaw txias dua, cov qauv compact, thiab kev saib xyuas yooj yim. Cov kev xaiv tshwj xeeb yuav tsum tau txiav txim siab raws li kev xav tau ntawm kev sim, pob nyiaj siv, thiab kev ua haujlwm. Yog li ntawd, nws raug pom zoo kom xaiv ib lub condenser kheej kheej los yog tubular condenser thaum cuam tshuam nrog cov viscosity siab evaporation. Lawv tuaj yeem muab cov nyhuv condensation zoo dua, txo qhov adhesion thiab scaling, thiab txhim kho evaporation efficiency. Thaum xaiv, ib tus tuaj yeem ntsuas qhov xav tau tiag tiag thiab cov xwm txheej kom ua tiav qhov kev sim zoo tshaj plaws.
