Cov txheej txheem luam yeeb ntau lawm yog qhov nyuaj heev. Los ntawm kev ua haujlwm ntawm cov luam yeeb tawm mus rau cov khoom tiav ntawm cov luam yeeb, nws yog qhov yuav tsum tau mus dhau ntawm ntau cov txheej txheem xws li tig thiab qhwv. Txhua cov txheej txheem yuav tsum tau khaws cia kom zoo thiab tswj kom zoo thiab pom ntawm luam yeeb nplooj raw cov ntaub ntawv thiab cov khoom luam yeeb tiav.
Tus kab mob zoo li xim zoo nkauj ntawm cov xim capillary nyob rau saum npoo ntawm cov luam yeeb nplooj, uas muaj cov suab thaj soluble, organic acids thiab cov zoo li, ua rau cov luam yeeb muaj cov hygroscopicity muaj zog heev.
Luam yeeb nws tus kheej muaj qee qhov dej, uas cuam tshuam rau cov dej hauv lub cev vim tias muaj cov tshuaj lom neeg xws li evaporation, nqus thiab diffusion raws li qhov kub thiab vaum pauv.
Thaum cov av noo yog siab: daim nplooj luam yeeb yuav nqus noo noo thiab ua rau lub cev mos thiab lwj. Lub luag haujlwm yuav ua rau kom nrawm nrawm thiab thaj chaw cuam tshuam loj dua.
Txawm li cas los xij, qhov chaw khaws khoom ntawm cov nplooj yeeb nkab yuav tsum tsis txhob qhuav dhau. Kev qhuav dhau lawm yuav ua rau cov dej haus ntawm cov luam yeeb tawm kom tawg, uas yuav cuam tshuam rau qhov zoo ntawm cov luam yeeb tsim tawm.
Yog li, qhov kub thiab noo ntawm lub chaw ua khoom luam yeeb ntau ntau, luam yeeb ntim, ntim chaw haus luam yeeb thiab lwm qhov chaw tsim luam yeeb yuav tsum raug tswj hwm nruj, thiab cov ntsiab lus hauv qab no yuav tsum ua tiav.
A: Thaum khaws cov pa luam yeeb tawm nplooj, feem ntau yuav tsum tau ua rau qhov chaw khaws cia kom qhuav, ntim, huv, tsis raug rau hnub ci ncaj qha, thiab tsis cuam tshuam ncaj qha los ntawm kev hloov pauv qhov ntsuas kub thiab noo. Cov txheej txheem ntsuas dej tsis zoo nyob hauv qab thiab ib ncig ntawm hauv av, thiab tuaj yeem khaws cia nyob sab ntawm qhov chaw 40 cm sab saud hauv av.
Thib ob: cov nplooj luam yeeb tawm ntawm cov qhov sib txawv thiab qhov sib txawv nyias yuav tsum muab txiav kom nyias thiab cov cim kom meej meej kom pab tau qib thiab xa. Thaum muab teem, cov ntsis ntawm daim nplooj sab hauv thiab hauv paus ntawm nplooj nplooj ntoo tawm sab nraud, thiab cov khaubncaws sab nraud povtseg yog txhav thiab tid. Tom qab muab kauv, npog nws nrog zaj duab xis yas, tsaj, thiab lwm yam, thiab npog qhov ntxoov ntxoo. Qhov siab tsis tshaj 1.5 meters. Qhov ntev thiab dav yog txiav txim siab raws li qhov xwm txheej tiag tiag.
Peb: Kev tshuaj xyuas tas li. Qhov kub sab hauv hauv pawg yuav tsum tswj hwm qis dua 35 ° C. Feem ntau, qhov kub thiab txias ntawm cov duab tshooj thiab cov dej noo noo ntawm cov nplooj ntawv luam yeeb yuav tsum kuaj ib zaug txhua 4-6 hnub. Thaum twg qhov kub siab tshaj 37 ° C, qhov kub yuav tsum tau muab tso tseg thiab cov pa luam yeeb nplooj yuav tsum tau nqa tawm hauv lub sijhawm.
