Daim ntawv thov ntawm cov kuab tshuaj rov qab tshuab hauv cov khoom siv kho qhov muag tau dhau los ua ntau dua, thiab cov tshuab no yog ib qho. Ib puag ncig tus phooj ywg thiab cov tswv yim daws teeb meem. Nws ua rau kev siv lub cev thiab cov khoom siv tshuaj lom neeg ntawm cov kuab tshuaj, kom cov kuab tshuaj rov qab tuaj yeem rov qab siv tau, xws li kev coj ua tsis yog tsuas yog txhim kho kev ua haujlwm ntawm cov khoom lag luam, tab sis kuj txuag nqi thiab txo cov khoom pov tseg los ntawm kev lag luam.
Hauv kev tsim cov khoom siv kho qhov muag, ntau hom kuab tshuaj yog siv, thiab feem ntau yuav tsum tau siv ntau, ua rau muaj ntau yam pov tseg thiab pov tseg. Qhov kom zoo dua ntawm kev siv lub tshuab hnyav rov qab yog tias nws tuaj yeem hloov pauv cov kuab tshuaj txaus rau hauv lub xeev gaseous los ntawm cov cuab yeej evaporation meej, tshem tawm cov dej seem thiab cov impurities, thiab tom qab ntawd cais cov tshuaj, thiab thaum kawg hloov cov kuab tshuaj mus rau hauv lub xeev ua kua rov qab. , txo cov pov tseg thiab kev siv nyiaj ntawm cov lag luam.
Piv nrog rau cov kev kho ib txwm siv, lub tshuab hnyav rov qab tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom hauv kev tsim khoom. Nrog rau lub tshuab no, tsis tsuas yog tuaj yeem pov tseg rau hauv cov ntaub ntawv zoo raw khoom, tab sis kuj tseem siv tau cov khoom siv ntxiv tuaj yeem ntxiv rau cov txheej txheem tsim khoom. Ua li no, lub tuam txhab tuaj yeem txuag tau nyiaj ntau thiab sijhawm, thiab tiv thaiv ib puag ncig thiab kev noj qab haus huv.
Peb yuav tsum txhawb kom cov tuam txhab lag luam ntau dua los siv cov tshuab hnyav rov qab. Cov thev naus laus zis no tuaj yeem tsis tsuas yog hloov cov khoom pov tseg rau hauv cov khoom muaj nqis, tab sis kuj zoo dua tiv thaiv ib puag ncig thiab tib neeg kev noj qab haus huv. Peb yuav tsum ua kom muaj txiaj ntsig zoo tshaj plaws ntawm cov khoom tsim los ntawm kev ua haujlwm thiab kev tswj hwm kev tswj hwm, tab sis kuj xav txog tej teeb meem ib puag ncig. Nyob rau hauv txoj kev no, peb tuaj yeem tso lub hauv paus rau kev tsim khoom ruaj khov thiab kev loj hlob rau yav tom ntej.
