Kev ziab kom qhuav yog txheej txheem txaus nyiam uas tau hloov pauv ntau yam kev lag luam, los ntawm kev khaws zaub mov mus rau kev tsim tshuaj. Raws li ntau tus neeg tshawb nrhiav lub ntiaj teb ntawm kev ziab qhuav, cov lus nug txog nws txoj kev siv ntau yam thiab cov kev txwv feem ntau tshwm sim. Ib lo lus nug no yog seb koj puas tuaj yeem muab ethanol tso rau hauv lub tshuab ziab khaub ncaws. Hauv tsab xov xwm no, peb yuav nkag mus tob rau hauv cov ncauj lus no, tshawb txog qhov cuam tshuam ntawm kev siv ethanol hauv cov tshuab ziab khaub ncaws, nrog rau kev tsom tshwj xeeb rauportable freeze dryers. Cia peb pib taug kev ntawm kev tshawb pom no thiab nthuav tawm qhov tseeb txog kev ziab kom qhuav thiab ethanol.
Nkag siab txog Kev Kho Kom Qhuav Qhuav thiab Nws Cov Ntawv Thov
Ua ntej peb delve rau hauv qhov tshwj xeeb ntawm kev siv ethanol hauv lub tshuab ziab khaub ncaws, nws yog ib qho tseem ceeb kom nkag siab tias qhov khov ziab yog dab tsi thiab nws ua haujlwm li cas. Kev ziab kom qhuav, tseem hu ua lyophilization, yog cov txheej txheem lub cev qhuav dej uas cuam tshuam nrog cov khoom khov thiab tom qab ntawd txo qis qhov chaw nyob ib puag ncig kom tso cai rau cov dej khov hauv cov khoom kom sublimate ncaj qha los ntawm cov khoom theem mus rau theem roj.
Qhov nrov ntawm kev ziab kom qhuav tau ua rau kev txhim kho ntau yam ntawm cov tshuab ziab khaub ncaws, nrog rau cov tshuab ziab khaub ncaws kom qhuav. Cov chav tsev me me no tau ua kom khov ziab kom yooj yim dua rau cov lag luam me, cov kws tshawb fawb, thiab txawm tias cov neeg nyiam uas xav tshawb nrhiav cov cuab yeej no hauv tsev.
Chemistry ntawm Ethanol thiab Nws Cov Khoom
Tam sim no, cia peb tig mus rau ethanol. Ethanol, tseem hu ua ethyl cawv, yog cov kua tsis muaj xim, flammable nrog ntau yam kev siv. Nws yog feem ntau siv los ua cov kuab tshuaj, roj additive, thiab thawj cov cawv hauv cov dej cawv. Nws cov qauv tshuaj yog C2H5OH, thiab nws muaj qee yam khoom tshwj xeeb uas ua rau nws nthuav dav hauv cov ntsiab lus ntawm khov kom qhuav:
Tsawg lub freezing point:
Ethanol khov ntawm {{0}} degree (-173.2 degree F), uas qis dua dej qhov chaw khov ntawm 0 degree (32 degree F).
High volatility:
Ethanol evaporates sai sai ntawm chav tsev kub.
Miscibility nrog dej:
Ethanol sib tov nkag nrog dej hauv txhua qhov sib npaug.
Cov khoom no tsa cov lus nug uas xav paub txog yuav ua li cas ethanol coj tus cwj pwm hauv lub tshuab ziab khaub ncaws, tshwj xeeb tshaj yog nyob rau hauv lub tshuab ziab khaub ncaws yooj yim tsim rau tsev lossis siv me me.
Koj puas tuaj yeem muab Ethanol tso rau hauv lub tshuab ziab khaub ncaws?
Tam sim no, los teb cov lus nug tseem ceeb: koj puas tuaj yeem muab ethanol tso rau hauv lub tshuab ziab khaub ncaws? Cov lus teb luv luv yog yog, tab sis nrog ob peb qhov tseem ceeb thiab kev txiav txim siab.
Kev ziab kom qhuav ethanol tuaj yeem ua tau, tab sis nws tsis yog ib txoj hauv kev yooj yim xws li khov kom qhuav dej-raws li tshuaj. Nov yog vim li cas:
Tsawg lub freezing point:
Raws li tau hais ua ntej, ethanol khov ntawm qhov kub qis dua li dej. Feem ntau cov tshuab ziab khaub ncaws txias, suav nrog cov tshuab ziab khaub ncaws uas siv tau, tsis yog tsim los kom ncav cuag qhov kub qis. Qhov no txhais tau hais tias cov ntshiab ethanol yuav tsis khov rau hauv lub tshuab ziab khaub ncaws.
Volatility:
Ethanol's volatility siab txhais tau tias nws tuaj yeem evaporate sai sai thaum lub sij hawm khov kom qhuav. Qhov evaporation sai no tuaj yeem ua rau lub tshuab ziab khaub ncaws khov lub tshuab nqus tsev lossis lwm yam khoom yog tias tsis tswj xyuas kom zoo.
Kev txhawj xeeb txog kev nyab xeeb:
Cov khoom siv txwv tsis pub: Cov tshuab ziab khaub ncaws yooj yim, tshwj xeeb, feem ntau yog tsim los siv hauv tsev nrog cov khoom noj. Tej zaum lawv yuav tsis muaj peev xwm lossis kev nyab xeeb uas yuav tsum tau siv rau kev tuav cov kuab tshuaj xws li ethanol.
Ethanol-dej sib tov:
Cov kev daws teeb meem uas muaj ethanol thiab dej tuaj yeem khov kom qhuav hauv qee qhov xwm txheej. Cov ntsiab lus dej pab txhawb nqa qhov chaw khov ntawm qhov sib tov, ua rau nws tsim nyog rau cov khoom siv khov qhuav qhuav.
Txawm li cas los xij, thaum khov kom qhuav ntshiab ethanol tsis pom zoo nyob rau hauv tus qauv lossis yooj yim lub tshuab ziab khaub ncaws, muaj qee qhov xwm txheej uas ethanol tuaj yeem koom nrog hauv cov txheej txheem khov kom qhuav:
Ethanol ua ib co-solvent:
Hauv qee qhov kev siv tshuaj thiab biotechnology, ethanol yuav raug siv los ua cov kuab tshuaj sib xyaw ua ke hauv cov tshuaj uas tom qab ntawd khov qhuav. Txawm li cas los xij, qhov no feem ntau yog ua nyob rau hauv cov khoom tshwj xeeb, qib-qib khov tshuab ziab khaub ncaws tsim los rau cov hom phiaj no.
Tus nqi ntawm ethanol:
Cov lej ntawm ethanol: Cov khoom lag luam uas muaj me me ntawm ethanol, xws li qee yam khoom noj lossis tshuaj ntsuab, feem ntau tuaj yeem khov kom qhuav yam nyab xeeb hauv lub tshuab ziab khaub ncaws. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias yog tias koj tab tom txiav txim siab siv lub tshuab ziab khaub ncaws yooj yim rau txhua lub hom phiaj uas muaj ethanol, koj yuav tsum tau sab laj nrog cov chaw tsim khoom cov lus qhia thiab cov lus qhia kev nyab xeeb ua ntej.
Rau cov neeg nyiam ua kom qhuav qhuav ethanol-muaj cov khoom siv rau kev tshawb fawb lossis kev lag luam, nws raug nquahu kom siv cov cuab yeej tshwj xeeb tsim los tuav cov tshuaj tsis haum tshuaj organic. Cov tshuab no feem ntau suav nrog cov yam ntxwv xws li cov khoom tawg-pov thawj, cov cuab yeej hnyav, thiab muaj peev xwm kub tsis tshua muaj zog.
