Cov kav hlau hlau tau siv dav hauv ntau yam kev lag luam rau lawv cov kav ntev thiab lub zog. Txawm li cas los xij, qhov teeb meem ntawm xeb tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo thiab kev ua neej nyob. Txhawm rau tiv thaiv cov kav hlau los ntawm xeb, muaj ntau txoj hauv kev uas tuaj yeem siv tau.
1.Txheej cov kav dej nrog cov tshuaj tiv thaiv corrosive lossis coatings:Ib txoj hauv kev zoo tshaj plaws los tiv thaiv xeb yog siv cov txheej txheem tsim nyog ntawm cov kav dej. Anti-corrosive paints thiab coatings tsim ib qho kev thaiv ntawm cov hlau nto thiab ib puag ncig, tiv thaiv cov hlau los ntawm kev sib cuag nrog noo noo thiab oxygen, uas yog lub ntsiab ua rau rusting.
Anti-corrosive paints lossis coatings yog siv los tiv thaiv cov kav hlau los ntawm xeb, corrosion, thiab lwm yam kev puas tsuaj. Cov txheej txheem no yog qhov tseem ceeb hauv kev ua kom lub neej ntev thiab ua haujlwm ntev ntawm cov kav dej steel, tshwj xeeb tshaj yog cov uas raug rau ib puag ncig hnyav.
Nov yog qee qhov feem ntau siv los tiv thaiv corrosive xim thiab coatings rau steel kav:
1) Epoxy txheej- Cov no yog ob feem txheej txheej uas muab kev tiv thaiv zoo tiv thaiv corrosion, puas, thiab tshuaj lom neeg. Epoxy txheej yog feem ntau siv nyob rau hauv industrial thiab marine ib puag ncig.
2) Polyurethane txheej- Cov no yog cov txheej txheem ua haujlwm siab uas muaj qhov tshwj xeeb tiv thaiv UV teeb, huab cua, thiab corrosion. Polyurethane coatings kuj zoo heev thiab muaj peev xwm tiv taus ib puag ncig hnyav.
3)Zinc-nplua nuj coatings- Cov txheej no muab kev tiv thaiv zoo heev tiv thaiv corrosion. Zinc-nplua nuj txheej tuaj yeem yog xim lossis hmoov txheej. Lawv feem ntau siv nyob rau hauv marine thiab industrial sectors.
4) Alkyd txheej- Cov no yog cov roj-raws li txheej txheej uas paub txog lawv qhov tshwj xeeb ruaj khov thiab tiv thaiv corrosion. Alkyd txheej yog feem ntau siv hauv kev tsim kho kev lag luam.
5) Ceramic Txheej- Cov no yog cov txheej txheem ua tau zoo uas muaj kev tiv thaiv zoo tiv thaiv corrosion, kub, thiab tshuaj lom neeg. Ceramic coatings feem ntau yog siv rau hauv tsheb thiab aerospace kev lag luam.
6) Acrylic Txheej- Cov no yog cov dej-raws li txheej uas muab kev tiv thaiv zoo tiv thaiv UV teeb, huab cua, thiab corrosion. Acrylic txheej yog feem ntau siv hauv kev tsim kho kev lag luam.
2.Galvanize cov kav dej:Galvanizing yog txheej txheem ntawm txheej steel kav nrog ib txheej ntawm zinc los tiv thaiv lawv los ntawm xeb. Lub zinc txheej yog kev txi, txhais tau hais tias nws corrodes ua ntej, tiv thaiv cov hlau hauv qab nws.
3. Khaws cov kav dej kom qhuav: Cov dej noo yog qhov tseem ceeb rau kev xeb, yog li ua kom cov kav dej kom qhuav yog qhov tseem ceeb. Qhov no tuaj yeem ua tiav los ntawm kev khaws cov kav dej hauv tsev hauv qhov chaw qhuav lossis los ntawm kev npog lawv nrog tarpaulins lossis lwm yam khoom siv dej tsis zoo.
4.Ua raws li kev saib xyuas kom raug: Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas cov kav hlau tuaj yeem pab tiv thaiv xeb. Qhov no suav nrog kev tu cov kav dej, tshem tawm cov kab xeb, thiab siv cov txheej tiv thaiv raws li qhov tsim nyog.
