1.Dab tsi yog cov ntsiab lus tseem ceeb rau kev tsim cov pa cua txias ntawm -rolled coils?
Khoom Siv Tau: Txias- cov nplooj ntawv steel yog tsim los ntawm cov pa roj carbon me me los ntawm kev yob txias. Lawv muaj ib tug du, huv si nto thiab kuj yog mos, ua rau lawv zoo tagnrho rau ductwork ua xws li seaming thiab folding. Lawv tau lees paub tias yog cov khoom tsim nyog tshaj plaws rau cov haujlwm ua cua txias. Cov qib siv feem ntau suav nrog Q195, Q215, thiab Q235, nrog cov tuab feem ntau ntawm 0.5mm txog 2mm.
Cov Txheej Txheem Tseem Ceeb: Qhov no yog cov kauj ruam tseem ceeb tshaj plaws. Txij li thaum txias- cov ntawv yob steel tsis muaj corrosion- txheej tiv thaiv, cov ducts tsim yuav tsum tau ua kom zoo xeb tshem tawm thiab tiv thaiv- kev kho corrosion. Hauv cov haujlwm ua haujlwm (xws li subway chaw nres tsheb qhov cua), cov qauv kev coj ua yog: ua ntej, tshem tawm xeb; tom qab ntawd, siv ob lub tsho tiv thaiv - xeb xim; thiab thaum kawg, siv ob lub tsho tiv thaiv hluav taws- cov xim retardant. Qhov no ua kom cov ducts tsis xeb thiab ua tau raws li lub tsev tsim kev nyab xeeb hluav taws. Qee qhov chaw hais tias annealing txias- cov ntawv hlau yob tuaj yeem tshem tawm cov kev ntxhov siab sab hauv uas tau tsim thaum khoov thiab vuam, tiv thaiv kev deformation thiab tawg.
2.Dab tsi yog txoj kev sib txuas?
Interlocking: Rau cov hlau phaj nrog lub thickness ntawm 1.2 hli los yog tsawg dua, kev sib cuam tshuam feem ntau yog siv, thiab qhov no yog txoj hauv kev tshaj plaws rau kev tsim cov kav dej.
Vuam: Rau cov hlau daim hlau nrog lub thickness ntau dua 1.2 hli, vuam (xws li hluav taws xob vuam lossis roj vuam) yog qhov tsim nyog dua.
3.Dab tsi yog cov yam ntxwv tseem ceeb ntawm txias -rolled steel sheet ducts?
Cov yam ntxwv tseem ceeb: Tus nqi qis, lub zog zoo, thiab kev ua haujlwm zoo heev.
Tsis muaj zog txaus: Tsis xeb- pov thawj; yuav tsum tau complex ntawm -site los yog Hoobkas painting.
Cov ntawv thov raug siv: Feem ntau yog siv rau tus nqi- cov ntawv thov nkag siab qhov twg tha xim tuaj yeem ua tau, xws li thaum ntxov- cov phiaj xwm theem, qhov cua thiab cov pa luam yeeb tawm hauv qee cov nroj tsuag lossis chaw nres tsheb subway.
4.Dab tsi yog cov yam ntxwv tseem ceeb ntawm galvanized steel ntawv ducts?
Cov yam ntxwv tseem ceeb: Los nrog kev tsim- nyob rau hauv galvanized txheej, muab cov xeb muaj zog thiab ci tiav.
Cov txheej txheem zoo: Tsis muaj kev pleev xim ntxiv tom qab tsim khoom; installation yog yooj yim thiab huv si, ua rau nws tam sim no mainstream xaiv.
Cov Ntawv Thov: Dav siv dav hauv cov cua tshuab thiab cua txias, tshwj xeeb tshaj yog tsim rau kev nplij siab cua txias thiab qhov chaw ntub dej nrog cov kev xav tau siab rau kev huv thiab kev tiv thaiv corrosion.
5.Dab tsi yuav tsum tau ceev faj thaum ua cov ducts ncaj qha los ntawm txias -rolled coils?
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov txog cov ducts uas tau ncaj qha los ntawm txias -rolled coils (tseem hu ua "dub hlau ntawv ducts"): lawv tsis xeb- pov thawj thiab yuav tsum tau tom qab nto tiv thaiv - kev kho corrosion.
