Hom Hlau Txheej Txheej: Ib qho Txheej Txheem

Classification ntawm steel coatings

Hlau txheej feem ntau poob rau hauv ob pawg dav: organic thiab inorganic. Organic coatings muaj xws li xim, hmoov txheej, epoxy, polyurethanes, thiab acrylics. Cov txheej txheem no yog ua los ntawm cov khoom sib txuas uas muaj cov pa roj carbon monoxide uas tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau. Cov txheej txheem inorganic feem ntau muaj cov txheej txheem hlau xws li zinc lossis ceramic cov ntaub ntawv uas muab kev tiv thaiv kev tiv thaiv thiab kev txi.

Nyob rau hauv cov pawg no, txheej txheej tuaj yeem raug cais ntxiv los ntawm lawv txoj kev siv, thickness, thiab tshuaj muaj pes tsawg leeg. Piv txwv li, galvanized coatings koom nrog kev siv zinc los ntawm kub-dip lossis electro-galvanizing, thaum hmoov txheej yog txau raws li cov hmoov qhuav thiab tom qab ntawd kho hauv qab cua sov.

Qhov sib txawv ntawm cov organic thiab inorganic txheej

Organic coatings tiv thaiv cov hlau feem ntau los ntawm kev tsim lub cev barrier uas tiv thaiv cov dej noo thiab oxygen los ntawm kev ncav cuag hlau. Lawv feem ntau muab cov kev xaiv zoo tshaj plaws ntawm cov xim thiab qhov chaw tiav, ua rau lawv nrov rau kev zoo nkauj thiab kev siv vaj tsev. Txawm li cas los xij, cov txheej txheem organic tuaj yeem degrade nyob rau hauv UV raug lossis cov tshuaj hnyav dhau sijhawm.

Inorganic txheej, zoo li zinc-raws li txheej, tiv thaiv hlau los ntawm kev ua raws li kev txi anodes. Zinc corrodes nyiam dua, sparing cov hlau hauv qab. Cov txheej txheem no yuav ua tau ntev dua tiv thaiv kev puas tsuaj thiab corrosion tab sis muaj tsawg dua cov xim xaiv. Ceramic coatings muab cov cua sov ua haujlwm thiab tshuaj lom neeg inertness, zoo tagnrho rau huab cua puag ncig.

Cov xwm txheej cuam tshuam rau kev xaiv cov hlau txheej

Ntau yam cuam tshuam rau cov txheej txheem steel uas haum rau ib daim ntawv thov tshwj xeeb:

• Ib puag ncig:  Corrosive lossis marine ib puag ncig yuav tsum tau coatings nrog muaj zog corrosion kuj, xws li galvanizing lossis epoxies.
