1.Vim li cas galvanized steel kauj yog cov khoom siv rau kev siv hluav taws xob hauv av?
Cov av noo siab: Cov huab cua tsis zoo nyob rau hauv qhov chaw siv hluav taws xob, kev nkag mus hauv av, thiab huab cua condensation tuaj yeem ua rau cov av noo ntev ntev.
Condensation: Kub variations tuaj yeem ua rau condensation los ntawm kev txhawb nqa thiab cov yeeb nkab nto.
Cov kab hluav taws xob tsis zoo (hauv qee thaj chaw): Yog tias muaj cov kev tsheb ciav hlau hluav taws xob lossis siab -voltage cables nyob rau hauv qhov chaw siv hluav taws xob, electrochemical corrosion yuav tshwm sim.
Tshuaj lom neeg: Muaj peev xwm tam sim no cov dej khib nyiab, tso pa tawm, thiab lwm yam.
2.Dab tsi yog qhov zoo ntawm galvanized coils (uas feem ntau ua tiav rau hauv galvanized steel strips lossis profiles) hauv kev teb rau cov teeb meem no?
Kev tiv thaiv corrosion zoo heev: zinc txheej muab lub cev ruaj khov thiab kev tiv thaiv cathodic (sacrificial anode) rau cov hlau, tiv thaiv corrosion los ntawm qhov chaw ntub dej thiab qhov dej.
Tus nqi siab-kev ua tau zoo: Piv rau qib siab- cov ntaub ntawv qib siab xws li stainless hlau, kub-dip galvanized steel yog qhov pheej yig dua, tswj tau tag nrho cov phiaj xwm peev thaum ua kom muaj kev nyab xeeb ntev -.
Lub zog siab thiab kev pab lub neej ntev: Kev txhawb nqa ua los ntawm galvanized coils muaj lub zog txaus thiab thauj khoom -cov kabmob muaj peev xwm, nrog rau kev tsim lub neej feem ntau tshaj 20-30 xyoo, sib piv cov qauv tsim lub neej ntawm cov yeeb nkab gallery.
Kev siv thev naus laus zis: Cov txheej txheem galvanizing yog qhov paub tab, ua kom ruaj khov zoo thiab ua kom muaj kev loj hlob - nplai ntau lawm thiab ua.
3.Dab tsi yog cov teeb meem thiab cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog?
Zinc Txheej Thickness yog qhov tseem ceeb
Kev siv hluav taws xob hauv av yog qhov ntev - lub sijhawm, cov txheej txheem tseem ceeb nrog kev tiv thaiv corrosion siab heev. Nws yog ib qho tseem ceeb uas yuav tau xaiv galvanized coils nrog cov zinc txheej tuab txaus. High-cov khoom siv cua sov galvanized feem ntau pom zoo, nrog zinc txheej hnyav ntawm Z200 (200g / m²) lossis siab dua, thiab zoo dua, Z275 (275g / m²). Ordinary, thinner electroplated zinc (xws li SECC) yog qhov tsis tsim nyog.
Kev Tiv Thaiv Kev Tiv Thaiv ntawm Txiav thiab Drilled Tshooj - Qhov yooj yim tshaj plaws saib xyuas!
Qhov no yog qhov tsis muaj zog tshaj plaws ntawm kev txhawb nqa galvanized. Thaum koj txiav, xuas nrig ntaus, los yog weld galvanized coils, zinc txheej ntawm cov ntsiab lus no puas, nthuav tawm cov hlau substrate.
Yog tsis muaj kev kho mob, corrosion yuav pib ntawm cov seem no thiab maj mam kis mus rau sab hauv.
Txoj hauv kev kom raug: "Zinc patching" yuav tsum tau siv rau txhua ntu machined. Cov txheej txheem muaj xws li:
Txau nrog zinc- nplua nuj xim: Qhov no yog txoj hauv kev zoo tshaj plaws.
Siv zinc-pab tshuaj kho raws.
Xyuas kom lub thickness ntawm txheej yog txaus los npog tus ntoo khaub lig-section.
4.Cov ncej-kub-dip galvanizing kauj ruam yog dab tsi?
Siv cov hlau zoo tib yam los yog cov ntaub ntawv (xws li Q235B), cov khoom siv ua ntej, txiav, thiab welded rau hauv ib lub bracket tiav.
Tom qab ntawd, tag nrho cov bracket raug rau "tag nrho kub-dip galvanizing."
Qhov zoo: Cov txheej zinc tag nrho npog txhua lub ces kaum, ntu, thiab vuam taw tes, ua kom tsis muaj seamless, txuas ntxiv tiv thaiv txheej nrog kev pom zoo corrosion.
5.Yuav ua li cas galvanized coil / ntawv raw cov ntaub ntawv thiab siv zinc rau tus ntoo khaub lig-section?
Yuav galvanized coils / nplooj ntawv nrog lub siab zinc txheej hnyav ncaj qha raws li cov ntaub ntawv raw.
Ua haujlwm txias, txiav, thiab xuas nrig ntaus raws li cov duab kos (tsis txhob ntawm - qhov chaw vuam ntau li ntau tau).
Ua tib zoo tshuaj tsuag tag nrho cov npoo txiav thiab cov phab ntsa sab hauv ntawm qhov tho qhov nrog zinc- nplua nuj xim.
