1.Dab tsi yog qhov tseem ceeb ntawm kev siv galvanized coils hauv txee tsim khoom?
Cia ib puag ncig: Txawm hais tias cov tsev khaws khoom feem ntau nyob hauv tsev, lawv tsis tuav qhov kub thiab av noo tas li. Cov dej noo nyob rau hauv cov huab cua, tshwj xeeb tshaj yog thaum lub caij los nag, nyob rau hauv cov ntug dej hiav txwv, los yog thaum muaj ib tug loj kub sib txawv thaum sawv ntxov thiab yav tsaus ntuj, yuav yooj yim ua rau condensation. Cov hlau qub yuav xeb sai sai, ua rau nws cov khoom tsis muaj zog -cov kabmob muaj peev xwm.
Zinc Protection Mechanism: Cov txheej txheem galvanized tiv thaiv cov hlau substrate nyob rau hauv ob txoj kev:
Lub cev Barrier: Cov txheej zinc tuab cais cov hlau substrate los ntawm huab cua thiab noo noo.
Kev Tiv Thaiv Electrochemical: Txawm tias me me khawb hauv cov txheej galvanized tsim ib lub cell ntawm galvanic ntawm cov hlau substrate thiab cov zinc nyob ib puag ncig. Cov tshuaj muaj zog ntau zinc ua raws li cov anode thiab corrodes nyiam, tiv thaiv cov hlau substrate (cathode) los ntawm corrosion. Cov txheej txheem no hu ua "sacrificial anode tiv thaiv."
2.Ntxiv rau kev tiv thaiv -corrosion, dab tsi lwm yam zoo li galvanized coil muaj rau racking?
Zoo heev Surface Appearance
Galvanized coils muaj qhov ci ntsa iab nyiaj, tsim kom muaj qhov zoo nkauj thiab zoo nkauj uas ua kom zoo nkauj ib puag ncig ntawm niaj hnub warehouses thiab supermarkets. Rau cov txee tso khoom (xws li hauv khw muag khoom), txheej galvanized kuj tuaj yeem txau (hmoov coated) los tsim ntau yam xim.
Siab zog thiab hardness
Lub hauv paus khoom ntawm galvanized coils rau shelving yog feem ntau txias - dov los yog siab - lub zog steel, uas yog tam sim no muaj lub zog zoo thiab rigidity, ua tau raws li cov load-cov khoom yuav tsum tau ntawm shelving. Cov txheej txheem galvanizing tsis txo qis nws cov khoom siv kho tshuab.
Cov txiaj ntsig nyiaj txiag siab
Piv nrog rau lwm yam corrosion-cov ntaub ntawv uas tiv taus steel hlau xws li stainless hlau, galvanized steel yog kim heev. Nws muab cov kev daws teeb meem uas ua rau muaj kev sib npaug zoo ntawm tus nqi, kev ua haujlwm, thiab kev pabcuam lub neej. Galvanizing tuaj yeem txuas ntxiv kev pab cuam lub neej ntawm cov hlau zoo tib yam los ntawm ob peb zaug, txawm tias kaum xyoo, nrog rau cov nqi kho mob tsawg kawg nkaus.
Kev ua haujlwm yooj yim
Galvanized coils tuaj yeem ua tiav ncaj qha rau hauv ntau yam ntoo khaub lig- cov duab ntu (xws li C- zoo li, Ω- zoo li, thiab tshwj xeeb- zoo li tus) siv lub yob- ua tshuab. Qhov no tso cai rau kev ua haujlwm siab ntau lawm thiab tsim nyog rau loj - teev cov txheej txheem ntau lawm.
3.Dab tsi yog hom galvanized coils siv rau racking?
Kub-Dip Galvanized Coil
Txheej txheem: Hlau coils yog dipped nyob rau hauv molten zinc (kwv yees li 450 degree).
Nta: Cov txheej zinc tshwm sim yog tuab (feem ntau 60-150μm lossis ntau dua), muab kev tiv thaiv corrosion zoo heev thiab ua haujlwm ntev.
Daim ntaub ntawv: Siv nyob rau hauv daim ntawv thov uas yuav tsum tau muaj corrosion kuj, xws li sab nraum zoov racking, txias saw logistics warehouses (tsawg kub, high humidity), thiab warehouses nyob rau hauv ntug hiav txwv dej. Nws yog cov khoom tseem ceeb rau hnyav- lub luag haujlwm racking thiab tsav- los ntawm racking.
Hluav taws xob- Galvanized Coil
Txheej txheem: Ib txheej ntawm zinc yog siv rau saum npoo ntawm steel kauj ntawm electrolysis.
Nta: Cov txheej zinc yog nyias (feem ntau 5-25μm), uas ua rau lub ntsej muag du thiab zoo ib yam uas haum rau cov tshuaj tsuag tom ntej.
Daim ntaub ntawv: Feem ntau yog siv rau lub teeb yuag racking, khw muag khoom shelving, thiab tso saib racks nyob rau hauv qhuav sab hauv ib puag ncig. Nws feem ntau yog siv los ua substrate rau xim -coated coils, thawj electroplated nrog zinc thiab tom qab ntawd xim -coated (spray-coated), ua tiav ob qho tib si xeb thiab kev zoo nkauj.
4.Dab tsi yog daim ntawv thov tshwj xeeb ntawm galvanized coils ntawm rhawv?
Txee uprights: Cov no yog cov thawj thauj khoom-cov kabmob thiab yuav tsum tau ua los ntawm siab- lub zog, corrosion- tiv taus steel, nrog kub -dip galvanized steel coils yog qhov kev xaiv.
Beams: Cov no yog cov khoom siv ncaj qha txhawb nqa cov khoom thauj thiab tseem xav tau lub zog siab thiab corrosion kuj.
rhawv: Rau pallet racks, racks tej zaum kuj yuav yob - ua los ntawm galvanized steel coils.
Ntau yam kev sib txuas thiab kev txhawb nqa: Cov no ua kom muaj kev ruaj ntseg ntawm tag nrho cov qauv khib.
5.Galvanized coils yog siv los ua cov khoom siv hauv kev tsim khoom niaj hnub. Nws ua lub luag haujlwm dab tsi?
Nws zoo kawg nkaus ua tau raws li cov kev xav tau ntawm racking rau lub zog, durability, kev nyab xeeb, thiab kev lag luam. Thaum xaiv, cov chaw tsim khoom yuav xaiv hom tsim nyog (kub-dip galvanized lossis electro-galvanized) thiab zinc txheej thickness ntawm galvanized kauj raws li racking kev siv ib puag ncig (hauv tsev / sab nraum zoov, qhuav / ntub), thauj khoom- qib, thiab pob nyiaj siv.
