Cov ntsaws ruaj ruaj yog qhov tsis tseem ceeb ntawm ntau hom khoom siv tshuab, thiab lawv cov lus qhia zoo li qub, cov lus qhia hauv qab no yog qee cov lus qhia rau kev siv .
Ua ntej kev teeb tsa, nco ntsoov tias kev sib khi ntawm cov khoom sib dhos thiab cov teeb meem tsis txaus ntseeg li cov khoom siv qub, uas yuav tsum muaj cov teeb meem zoo li qub, uas yuav tsum muaj cov teeb meem zoo li qub tiav .
Thaum lub sij hawm cov txheej txheem teeb tsa, ua tib zoo saib xyuas kom tsis txhob khawb lossis ua kom haum rau cov khoom sib xyaw ua ntej, tab sis kuj txuas ntxiv rau lawv cov kev pabcuam lub neej rau ib qho kev pabcuam lub neej rau qee yam.
Thaum siv, nws yog qhov tseem ceeb los ua kom zoo rau cov kev ua haujlwm ntawm lub sijhawm, nws yuav tsum tau ua kom muaj qhov tsis sib xws rau cov qauv ntsuas tsis tu ncua {}}}}} ntev tshaj plaws kub thiab siab yuav ua kom nrawm nrawm ntawm cov laus ntawm cov ntxig li qub thiab txo lawv cov kev ua haujlwm sib khi {}}
Nws tseem tsim nyog xaiv cov ntaub ntawv uas tsim nyog cov ntaub ntawv zoo li qub raws li kev ua haujlwm tiag tiag, hauv qhov kub thiab txias tiv taus roj hmab lossis cov khoom siv hlau tuaj yeem raug xaiv; nyob rau hauv ib puag ncig nrog corrosive media, corrosion-resistant sealing cov ntaub ntawv yuav tsum tau siv los xyuas kom qhov kev ntseeg tau thiab muaj kev ruaj khov ntawm cov npliag ntawm lub ntsej muag {2 2}}
Tsis tas li ntawd, tsim kom tiav txoj kev npaj tu ua kom tswj thiab hloov pauv lub neej qub tam sim no, nws txoj kev ua tau zoo li cas los xij
Mastering cov lus qhia no rau kev siv cov ntawv sau zoo li qub yuav pab txhim kho cov khoom siv ua haujlwm, txo cov nqi kho mob, txo cov nqi kho mob, txo cov nqi tau rau kev tsim cov lag luam {}}
