Hauv kev ua haujlwm ntawm kev lag luam khoom siv, lub luag haujlwm ntawm cov ntsaws ruaj ruaj. Raws li qhov tseem ceeb ntu, cov ntsaws ruaj ruaj tsis yog qhov muag pom raws li cov ntsaws ruaj ruaj, tab sis lawv ua haujlwm hauv kev ua kom muaj kev nyab xeeb, ruaj khov thiab ua haujlwm ruaj khov ntawm cov cuab yeej.
Cov ntsaws ruaj ruaj yog cov cuab yeej sib khi siv los tiv thaiv cov kua dej (roj lossis kua) to hauv lub xeev zoo li qub. Nws yog feem ntau ntsia nruab nrab ntawm cov khoom nyob ruaj ruaj ntawm cov khoom siv, cov hluav taws xob sib txuas, zoo li cov ntsaws ruaj ruaj uas haum rau qhov chaw ruaj khov los tiv thaiv cov xau ntawm cov ntsaws nruab nrab.
Hais txog cov ntaub ntawv, zoo li cov ntsaws ruaj ruaj yog ntau. Cov uas muaj cov khoom siv rubbers, xws li nitrile roj hmab, thiab lwm yam, uas muaj cov khoom siv tshuaj ntsuab thiab muaj peev xwm hloov kho kom yooj yim thiab cov chaw nruab nrab; Cov ntaub ntawv, xws li polytetrosraethylene, muaj cov tshuaj ruaj khov thiab tuaj yeem tiv taus corrosion los ntawm yuav luag txhua qhov tshuaj lom neeg ib puag ncig; Tseem muaj cov hlau, xws li tooj liab gaskets, thiab lwm yam, uas muaj lub zog siab thiab muaj cov khoom siv kub siab thiab kub-ib puag ncig.
Cov ntsaws ruaj ruaj yog siv dav hauv ntau daim teb. Hauv kev lag luam petrochemical, nws tuaj yeem ua kom muaj kev sib khi ntawm ntau reactors thiab raj xa dej, tiv thaiv cov dej xau, thiab muaj kev nyab xeeb ntau; Nyob rau hauv lub hwj chim teb, kev sib txuas ntawm cov khoom siv xws li cov tshuab raj thiab cov tshuab hluav taws xob tsis tuaj yeem sib cais ntawm cov khoom lag luam qub qub los tswj cov haujlwm qub ntawm cov khoom siv; Hauv cov khoom noj thiab cov tshuaj lag luam, cov ntaub qhwv zoo li qub ntsib nruj kev nyiam tu cov qauv kev nyiam huv thiab muaj kev nyab xeeb.
Nrog kev txhim kho kev lag luam txuas ntxiv ntawm kev lag luam thev naus laus zis, kev ua tau zoo uas yuav tsum tau ua rau cov ntsaws ruaj ruaj tau nce siab dua thiab siab dua. Nyob rau yav tom ntej, zoo li qub ntsaws ruaj ruaj yuav tsim kho hauv kev coj ua ntawm kev ua tau zoo, lub neej ntev, kev tiv thaiv ib puag ncig, txuag hluav taws xob ib puag ncig. Tsis tu ncua txhim kho qhov zoo thiab kev ua tau zoo ntawm cov ntsaws ruaj ruaj tuaj yeem muab cov haujlwm ua haujlwm tau zoo rau kev lag luam cov cuab yeej siv thiab txhawb nqa kev txhim kho muaj txiaj ntsig zoo ntawm ntau yam kev lag luam.
