1.Yuav ua li cas cov tshuaj muaj pes tsawg leeg thiab kev tiv thaiv mechanisms ntawm galvanized coils thiab zinc{1}}aluminium-magnesium coils piv?
Galvanized Coil:
Muaj pes tsawg leeg: Feem ntau cov zinc ntshiab (Zn ntsiab lus> 99%).
Kev tiv thaiv Mechanism: Sacrificial anodic tiv thaiv. Zinc yog tshuaj lom neeg ntau dua li hlau. Thaum cov txheej txheej puas lawm, zinc corrodes ua ntej hlau, yog li tiv thaiv cov hlau hauv qab. Qhov no yog ib daim ntawv ntawm "tus kheej-kev txi" kev tiv thaiv.
Zinc{0}}Aluminium-Magnesium Coil:
Muaj pes tsawg leeg: Zinc (Zn) yog lub hauv paus, nrog ntxiv aluminium (Al, kwv yees li 5-11%) thiab magnesium (Mg, kwv yees li 1-3%), nrog rau cov lej ntawm silicon thiab lwm yam khoom.
Kev Tiv Thaiv Mechanism: Triple Protection Mechanism:
1. Sacrificial anodic tiv thaiv: Zoo ib yam li galvanizing, zinc thiab magnesium muab kev tiv thaiv kev txi.
2. Dense Barrier Protection: Aluminum forms a very dense aluminum oxide film on the surface, effectively blocking the intrusion of corrosive media.
3. Tus kheej-Kev Tiv Thaiv Kev Kho Mob: Qhov no yog qhov sib txawv tseem ceeb tshaj plaws. Lub xub ntiag ntawm magnesium tso cai rau cov khoom siv corrosion (xws li magnesium hydroxide thiab zinc chloride yooj yim) kom ruaj khov lub tsho txiav thiab khawb, tsim cov yeeb yaj kiab tiv thaiv uas ua rau muaj kev sib kis ntawm corrosion. Qhov no yog qhov ua li ntawd -hu ua "tus kheej- kho" ua haujlwm.
2.Yuav ua li cas lub zuag qhia tag nrho corrosion kuj ntawm ZnAlMg thiab galvanized coils piv?
Nyob rau tib lub txheej hnyav (piv txwv li g / ㎡), lub neej corrosion kuj ntawm zinc- txhuas-magnesium feem ntau yog 2 mus rau 10 npaug los yog siab dua li qhov qub galvanizing. Qhov zoo yog tshwj xeeb tshaj yog nyob rau hauv hnyav tej yam kev mob xws li industrial cua thiab marine ib puag ncig.
3.Dab tsi yog qhov txawv ntawm kev txiav thiab khawb tiv thaiv ntawm galvanized kauj thiab zinc-aluminium-magnesium kauj?
Galvanized coils: Lawv qhov tsis muaj zog tshaj plaws yog kev txiav thiab ua kev puas tsuaj. Thaum cov ntawv hlau raug txiav, cov hlau tsis muaj steel substrate raug ncaj qha, thiab cov zinc txheej tsuas tuaj yeem muab kev tiv thaiv tsis pub dawb rau thaj chaw uas nyob ib sab tam sim ntawd. Liab xeb ntawm qhov txiav tuaj yeem sai sai kis thoob plaws tag nrho cov ntawv saum npoo.
Zinc-aluminium-magnesium coils: Ua tsaug rau lawv "tus kheej- kho" cov khoom, cov khoom siv corrosion ua rau lub ntsej muag txiav, tsim cov txheej tiv thaiv uas tiv thaiv kev sib kis ntawm cov xeb liab. Txawm tias tom qab ntau tshaj li kaum xyoo, qhov ntev ntawm corrosion ntawm qhov txiav tseem txwv heev.
4.Yuav ua li cas khawb tsis kam ntawm zinc-aluminium-magnesium coil piv rau ntawm galvanized kauj?
ZnAlMg txheej feem ntau nyuaj dua thiab hnav ntau dua- tiv taus ntau dua li cov zinc txheej ntshiab, thiab tsis tshua muaj kev cuam tshuam rau kev khawb thaum ua, kev thauj mus los thiab kev teeb tsa, yog li tswj lawv cov khoom tiv thaiv zoo dua.
5.Dab tsi yog qhov xwm txheej ntawm kev xaiv galvanized kauj?
Cov peev nyiaj- txwv tsis pub thiab tus nqi-sensitive.
Rau siv nyob rau hauv qhuav nyob rau hauv ib puag ncig, nrog tsawg heev corrosion.
Cov khoom tsis raug cuam tshuam rau xeb ntawm cov txiav (xws li, ntawm cov khoom siv los yog pleev xim rau qhov chaw).
Rau cov haujlwm luv luv - cov haujlwm uas yuav tsum tau ua haujlwm tsawg kawg nkaus.
