Nqus concentration: txhim kho kev ua haujlwm ntawm cov txheej txheem kev lag luam
Lub tshuab nqus tsev concentration yog cov txheej txheem siv dav hauv ntau cov txheej txheem kev lag luam kom tshem tawm cov kua ntau dhau los yog hnyav los ntawm cov qauv lossis cov kev daws teeb meem.Kuj tseem hu ua lub tshuab nqus tsev vacuum evaporation, txoj kev no ua haujlwm nyob rau hauv kev txo qis, ua kom evaporation zoo dua thiab sai dua li cov txheej txheem ib txwm muaj.Hauv tsab xov xwm no, peb yuav tshawb txog cov hauv paus ntsiab lus tom qab lub tshuab nqus tsev thiab nws cov kev siv hauv kev lag luam sib txawv.
Vacuum concentration txheej txheem:
Lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev concentration yog txo qis qhov kub ntawm cov kua ntawm qhov qis dua.Los ntawm kev txo lub siab nyob rau hauv lub kaw lus kaw, lub boiling point ntawm cov tshuaj yog txo qis thiab cov kua evaporates yooj yim dua.Lub tshuab nqus tsev concentrator muaj lub tshuab nqus tsev twj tso kua mis uas tsim thiab tswj lub siab xav tau, tswj cov cua sov uas muab lub zog rau evaporation, thiab lub condenser uas sau thiab rov qab cov kuab tshuaj evaporated.
Cov txiaj ntsig thiab kev siv ntawm lub tshuab nqus tsev concentration:
1. Ua tau zoo thiab ceev ceev evaporation: Lub tshuab nqus tsev concentration tseem ua rau cov txheej txheem evaporation sai dua, tso cai kom tshem tawm cov kuab tshuaj sai dua piv rau cov txheej txheem ib txwm muaj.Qhov no nce efficiency txuag lub sij hawm thiab lub zog, ua rau nws ib tug zoo tagnrho technology rau ntau yam lag luam.
2. Concentration of heat-sensitive liquids: Qee cov kua yog rhiab heev rau qhov kub thiab txias thiab yuav decompose los yog poob lawv cov khoom uas yuav tsum tau thaum siv cov txheej txheem cua sov.Lub tshuab nqus tsev concentration ua haujlwm ntawm qhov kub thiab txias, txo qhov kev pheej hmoo ntawm kev degradation thiab ua kom ntseeg tau tias qhov xav tau zoo yog khaws cia.
3. Solvent rov qab: Lub tshuab nqus tsev concentration tuaj yeem rov qab tau yooj yim thiab rov siv cov kuab tshuaj dua.Cov kuab tshuaj evaporated tuaj yeem condensed thiab sau rau rov siv dua, txuag nqi thiab txo kev cuam tshuam ib puag ncig.
4. Kev lag luam kws tshuaj: Lub tshuab nqus tsev concentration plays lub luag haujlwm tseem ceeb hauv kev tsim tshuaj vim nws pab txhawb kev tshem tawm cov kuab tshuaj hauv cov tshuaj npaj thiab ua kom qhuav ntawm cov tshuaj intermediates.Cov tshuab no ua kom muaj kev nyab xeeb, purity thiab zoo ntawm cov khoom kawg.
5. Kev ua zaub mov: Lub tshuab nqus tsev yog siv dav hauv kev lag luam khoom noj kom tshem tawm cov dej noo ntau dhau ntawm cov kua lossis cov khoom noj ib nrab.Cov txheej txheem no pab mloog cov kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo thiab cov kua txiv hmab txiv ntoo, txhim kho lawv cov tsw thiab ua rau lawv lub neej txee.
6. Kev siv ib puag ncig: Cov chaw kho dej khib nyiab siv lub tshuab nqus tsev kom tshem tawm cov dej ntau dhau los ntawm cov dej khib nyiab, yog li txo cov khoom pov tseg.Txoj hauv kev no tsis yog tsuas yog pab txo cov pa phem ib puag ncig xwb tab sis kuj rov qab cov khoom muaj txiaj ntsig los ntawm cov dej khib nyiab.
7. Kev tsim tshuaj: Lub tshuab nqus tsev yog siv dav hauv cov txheej txheem tsim tshuaj.Nws pab tshem tawm cov kuab tshuaj los ntawm ntau yam tshuaj tiv thaiv, ua rau cov ntshiab thiab muaj zog sib xyaw.Cov tshuab no tseem ceeb tshwj xeeb tshaj yog rau cov khoom kub-rhiab los yog volatile.
Hauv cov ntsiab lus, lub tshuab nqus tsev yog ib txoj hauv kev zoo rau kev tshem tawm cov kua ntau dhau los yog hnyav los ntawm ntau yam khoom thiab tau siv dav hauv kev lag luam xws li tshuaj, kev ua zaub mov, kev tsim tshuaj, thiab kev kho dej khib nyiab.Nws muaj peev xwm ua kom nrawm evaporation, txo qhov raug tshav kub thiab ua kom hnyav rov qab ua rau nws muaj txiaj ntsig zoo rau kev txhim kho kev ua haujlwm, txo cov nqi thiab ua kom cov khoom zoo kawg.Nrog rau kev nce qib thiab kev txhim kho txuas ntxiv, lub tshuab nqus tsev concentration yuav nyob twj ywm hauv kev siv thev naus laus zis hauv ntau cov txheej txheem kev lag luam hauv xyoo tom ntej.
