1.Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm galvanized coils ua cov khoom siv rau cov khoom xa tawm?
Zoo heev Corrosion Resistance - Qhov Zoo Tshaj Plaws
Cov Kev Sib Tw ntawm Sab Nraud Ib puag ncig: Kev nthuav qhia lockers yuav tsum tau muab tso rau sab nraum zoov xyoo - puag ncig, raug kev yaig ntawm lub hnub, nag, daus, huab cua noo, thiab cov pa phem (xws li ntsev, kua qaub, thiab alkalis).
Galvanized Txheej Kev Tiv Thaiv: Cov txheej zinc tiv thaiv cov hlau hauv ob txoj hauv kev:
Barrier Protection: The dense zinc layer physically isolates the steel base from the corrosive environment.
Kev Tiv Thaiv Kev Txhaum Cai Anodic: Txawm hais tias cov zinc txheej yog khawb, nthuav tawm cov hlau, zinc ua raws li "kev txi" corrosion ua ntej hlau, yog li tiv thaiv lub hauv paus hlau los ntawm xeb. Qhov no ua kom lub neej ntev ntawm lub locker.
2.Vim li cas galvanized coils zoo tagnrho rau kev nthuav qhia lockers?
Zoo heev muaj zog thiab Rigidity
Txias- dov galvanized ntawv hlau muaj cov khoom siv zoo heev, ua rau kev tsim khoom ntawm cov khoom txee ruaj khov uas tiv taus qhov cuam tshuam thiab compression ntawm kev siv txhua hnub thiab muaj qee qhov kev puas tsuaj los ntawm kev tiv thaiv (xws li, kev tiv thaiv pry).
Kev ua tau zoo heev
Galvanized coils (tshwj xeeb tshaj yog cov uas tau annealed) muaj ductility zoo heev thiab formability, ua rau lawv zoo tagnrho rau cov ntawv hlau fabrication xws li txiav, stamping, thiab dabtsi yog khoov. Lawv tuaj yeem siv los tsim ntau yam ntawm cov txheej txheem nyuaj, qhov rooj panels, partitions, thiab ntau dua rau kev nthuav qhia lockers.
Lub hauv paus zoo meej rau Painting
Kev nthuav qhia lockers feem ntau yog tshuaj tsuag - pleev xim rau ntau yam xim (xws li Fengchao's liab, Tuam Tshoj Post's daj, thiab Cainiao's xiav) thiab cov cim npe.
Qhov huv thiab zoo ib yam ntawm cov ntawv hlau galvanized muab lub hauv paus zoo rau cov hmoov txheej tom ntej. Kev adhesion zoo tiv thaiv cov txheej los ntawm flaking, ua kom ntev - kav ntev, zoo nkauj zoo nkauj. Cov teeb meem yav dhau los tau tham txog "surface oil stain" tau hais meej meej thaum lub sijhawm tsim khoom tsis tu ncua los ntawm kev ua ntej -kev kho degreasing txheej txheem los xyuas kom meej txheej zoo.
3.Dab tsi yog cov khoom siv hauv txee thiab cov txheej txheem tsim khoom?
Cov khoom siv hauv paus: Txias- dov, qis- carbon steel galvanized kauj. Feem ntau zinc txheej hnyav suav nrog Z60 (60g / m²) thiab Z80 (80g / m²), uas tuaj yeem xaiv raws li cov khoom tshwj xeeb hauv txee thiab kev tiv thaiv corrosion.
Pretreatment: Tom qab flattening, shearing, stamping, thiab dabtsi yog khoov, steel phaj nkag mus rau hauv pre{0}}painting kab, uas muaj xws li cov hauv qab no:
Degreasing: Tshem tawm tag nrho cov roj thiab cov khoom paug, xws li cov roj dov thiab xeb -cov roj pov thawj, tau tham yav dhau los.
Kev kho kev hloov pauv (phosphating lossis passivation): Ua ib zaj duab xis hloov dua siab tshiab ntawm cov hlau nto, ntxiv txhim kho corrosion kuj thiab xim adhesion.
Txheej txheej:
Hmoov txheej: Qhov no yog cov txheej txheem nrov tshaj plaws. Hmoov txheej yog siv rau lub txee nto los ntawm electrostatic attraction thiab tom qab ntawd kho ntawm qhov kub thiab txias. Cov hmoov txheej uas tshwm sim yog cov tuab tuab, hnav- tiv taus, thiab huab cua- tiv taus, thiab muaj ntau yam xim.
Kev sib dhos: Cov khoom pleev xim yog sib sau ua ke nrog cov khoom siv sab hauv xws li cov xauv, cov ntxaij vab tshaus, thiab cov rooj sib tham.
4.Yuav ua li cas galvanized kauj ua piv rau txhuas?
Nws muaj kev tiv thaiv corrosion zoo thiab yog lub teeb yuag, tab sis nws cov nqi siab dua li ntawm cov ntawv hlau galvanized thiab nws lub zog yog qhov tsawg, yog li nws tsis tshua muaj siv nyob rau hauv cov khoom siv uas yuav tsum tau muaj zog.
5.Yuav ua li cas galvanized coil piv rau stainless hlau?
Nws muaj kev tiv thaiv corrosion zoo heev, tab sis tus nqi siab heev. Nws feem ntau tsuas yog siv nyob rau hauv qee qhov siab -kawg kho cov txee lossis cov khoom tshwj xeeb uas yuav tsum muaj kev tiv thaiv corrosion heev. Raws li kev xav txog tus nqi, cov khoom loj - nplai nthuav dav tsis tshua siv nws hauv tag nrho cov txee.
