Galvanized steel kav feem ntau yog siv rau hauv kev tsim kho vaj tse, kev siv dej thiab kev tso dej, hluav taws kub - cov kav dej sib ntaus sib tua, thiab ntau yam khoom siv hlau, uas lawv feem ntau yuav tsum tau khoov kom tau raws li ntawm - thaj chaw. Cov txheej txheem khoov yuav zoo li ncaj nraim, kev ua haujlwm tsis raug tuaj yeem ua rau cov txheej txheem galvanized tau yooj yim, ua rau deformation, tawg, lossis ntxov ntxov corrosion ntawm cov yeeb nkab steel. Yog li ntawd, yuav ua li cas khoov cov kav dej galvanized rau ntawm qhov chaw ntawm kev ua kom muaj zog ntawm cov qauv thiab kev tiv thaiv kev ua haujlwm corrosion yog ib qho teeb meem uas yuav tsum tau them sai sai rau thaum tsim kho thiab ua haujlwm.
Kab lus no yuav pib los ntawm cov yam ntxwv ntawm cov kav dej galvanized, piav qhia txog cov txheej txheem kom raug, cov ntsiab lus ntawm cov txheej txheem, thiab cov kev nkag siab tsis zoo hauv kev siv tswv yim rau kev khoov cov kav dej galvanized, pab cov neeg nyeem ntawv tsim cov kev paub txog kev ua haujlwm thiab cov txheej txheem.
1. Vim li cas cov kav dej Galvanized yog qhov nyuaj rau khoov
Galvanized kav yog qhov tseem ceeb tsawg- cov pa roj carbon steel kav raws li cov khoom siv hauv paus, npog nrog zinc txheej ntawm qhov chaw. Hlau nws tus kheej muaj ductility zoo, tab sis galvanized txheej yog nkig, thiab nws cov ductility yog qis dua li ntawm cov hlau matrix. Thaum lub sij hawm khoov, sab nraud ntawm cov yeeb nkab steel yog ncab, thiab kev ntxhov siab yog concentrated rau ntawm galvanized txheej. Yog tias lub vojvoog dabtsi yog khoov me me los yog lub zog tsis sib npaug, nws yooj yim ua rau cov zinc txheej tawg, tev, lossis poob.
Thaum cov zinc txheej puas lawm, cov hlau hauv qab yog ncaj qha mus rau huab cua lossis noo noo, thiab pitting corrosion thiab xeb yuav tshwm sim tom qab. Qhov no kuj yog qhov laj thawj tseem ceeb vim li cas ntau cov kav dej galvanized pib pom cov cim ntawm corrosion ntawm qhov chaw khoov. Yog li ntawd, kev khoov ntawm cov kav dej galvanized tsis yog ib qho yooj yim geometric deformation teeb meem, tab sis ib tug txheej txheem systematic nrog rau cov ntaub ntawv tiv thaiv thiab ntev - kev pab cuam lub sij hawm.
2. Kev nkag siab zoo txog kev xaiv txoj kev khoov rau cov kav dej Galvanized
Hauv kev tsim vaj tsev, txoj kev khoov ntawm cov kav dej galvanized yuav tsum raug xaiv raws li cov yeeb nkab txoj kab uas hla, phab ntsa thickness, thiab kev siv scenario. Rau me me - txoj kab uas hla, nyias- cov kav dej galvanized phab ntsa, qhov khoov txias feem ntau ua tau, tab sis lub vojvoog dabtsi yog khoov yuav tsum tau tswj kom tsis txhob yuam kev. Rau nruab nrab thiab loj - txoj kab uas hla los yog tuab - cov kav dej galvanized phab ntsa, nws muaj kev nyab xeeb dua los siv cov khoom siv yeeb nkab dabtsi yog khoov rau qeeb thiab sib xws.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev khoov cov kav dej los yog siv cov cuab yeej yooj yim rau kev quab yuam yog txoj hauv kev uas feem ntau ua rau cov txheej galvanized puas. Txawm hais tias cov haujlwm zoo li no txuag lub sijhawm thiab kev siv zog, lawv feem ntau nteg qhov kev tiv thaiv corrosion hauv lub sijhawm luv luv thiab tsis haum rau cov kav dej engineering uas yuav tsum tau ua haujlwm ntev.
3. Cov ntsiab lus tseem ceeb rau cov kav dej txias bending Galvanized
Txias bending yog txoj kev khoov tshaj plaws rau cov kav dej galvanized, xa mus rau kev tsim cov yeeb nkab steel los ntawm kev siv tshuab quab yuam ntawm chav tsev kub. Thaum khoov txias, lub vojvoog dabtsi yog khoov yog qhov tseem ceeb tswj qhov tseem ceeb. Qhov loj dua lub vojvoog dabtsi yog khoov, qhov sib txawv ntawm cov khoom siv quab yuam, thiab qis dua qhov kev pheej hmoo ntawm kev puas tsuaj rau txheej galvanized.
Hauv kev ua haujlwm zoo, kev khoov ntse ntse thiab txoj cai- lub kaum sab xis yuav tsum zam kom ntau li ntau tau, thiab kev khoov qeeb yuav tsum tau txais yuav los maj mam tso cov kev ntxhov siab ntawm cov yeeb nkab phab ntsa. Nyob rau tib lub sijhawm, kev khoov ceev yuav tsum tau ceev kom ruaj khov kom tsis txhob siv lub zog tam sim ntawd lossis rov kho lub kaum sab xis, uas yuav ua rau muaj kev ntxhov siab hauv zos.
Yog tias cov kab nrib pleb zoo los yog xim dawb tshwm rau saum npoo ntawm txheej txheej galvanized tom qab txias khoov, qhov khoov yuav tsum tau kho kom tiv thaiv- corrosion raws sijhawm kom tsis txhob xeb ntxiv.
4. Kev tsim nyogthiab pheej hmoo ntawm Kub dabtsi yog khoov Galvanized kav
Hauv qee qhov xwm txheej tshwj xeeb, cov neeg ua haujlwm tsim kho yuav xav txog dabtsi yog khoov galvanized kav los ntawm cua sov. Nws yuav tsum tau muab sau tseg tias kub dabtsi yog khoov tsis haum rau feem ntau galvanized yeeb nkab tej yaam num.
Thaum cov kav dej galvanized raug rhuab mus rau qhov kub siab, cov zinc txheej yuav oxidize los yog volatilize, uas tsis yog tsuas yog ua phem rau lub anti{0}}corrosion txheej tab sis kuj ua rau zinc fumes tsim teeb meem rau kev noj qab haus huv, ua rau muaj kev hem thawj rau kev tsim kho kev nyab xeeb. Nyob rau tib lub sij hawm, zinc txheej nyob rau hauv lub rhuab cheeb tsam yeej poob nws cov kev tiv thaiv nyhuv, thiab tus nqi corrosion accelerates ho tom qab.
Yog li ntawd, tshwj tsis yog tias nws yog qhov tsim nyog ua haujlwm thib ob nrog cov txheej txheem zinc txheej tiav, kev khoov kub tsis pom zoo rau cov kav dej galvanized. Hauv cov phiaj xwm txheej txheem, kub dabtsi yog khoov feem ntau suav tias yog cov txheej txheem tsis pom zoo.
5. Kev tiv thaiv kev ua haujlwm ntawm cov khoom siv yeeb nkab dabtsi yog khoov ntawm cov kav dej Galvanized
Siv cov yeeb nkab tshwj xeeb bender yog ib qho qauv tsim thiab txhim khu kev qha rau bending galvanized kav tam sim no. Cov cuab yeej tshaj lij tuaj yeem ua haujlwm tsis tu ncua thiab sib npaug ntawm cov yeeb nkab steel nyob rau hauv qhov chaw khoov lub vojvoog, txo qhov tshwm sim ntawm kev puas tsuaj rau txheej txheej galvanized.
Thaum lub sijhawm ua haujlwm, cov yeeb nkab bender tuaj yeem tswj tau qhov kev ntxhov siab ntawm cov yeeb nkab phab ntsa, txo cov elliptical deformation thiab wrinkling, thiab xyuas kom meej qhov tseeb ntawm lub kaum sab xis. Qhov no yog ib qho tseem ceeb tshwj xeeb rau engineering tej yaam num uas yuav tsum tau rov ua dua los yog muaj kev xav tau siab.
Thaum cov xwm txheej tso cai, ntawm - qhov chaw khoov ib ntus yuav tsum zam kom ntau li ntau tau, thiab cov yeeb nkab dabtsi yog khoov yuav tsum ua kom tiav hauv lub Hoobkas, uas yog qhov tsim nyog rau kev tswj hwm tag nrho.
6. Ncej -BendingKev tiv thaiv thiab tshuaj xyuas cov kav dej Galvanized
Tom qab cov yeeb nkab galvanized yog khoov, tom qab kev tshuaj xyuas thiab kev tiv thaiv kev ua haujlwm tsis tuaj yeem tsis quav ntsej. Qhov khoov ib feem yuav tsum tau tsom rau kev soj ntsuam seb cov zinc txheej puas muaj cov kab nrib pleb, tev, lossis pom tseeb tsis muaj xim. Yog tias pom muaj kev puas tsuaj hauv zos rau cov zinc txheej, cov xim txias galvanizing lossis zinc- nplua nuj los tiv thaiv- txheej txheej corrosion yuav tsum tau siv los kho kom raws sijhawm kom rov qab tau cov txheej txheem tiv thaiv -corrosion.
Nyob rau tib lub sijhawm, nws tseem yuav tsum tau kuaj xyuas seb qhov khoov puas muaj qhov pom tseeb ntawm cov yeeb nkab txoj kab uas hla deformation lossis sab hauv phab ntsa wrinkling, uas yuav cuam tshuam rau lub siab -cov kabmob muaj peev xwm thiab cov dej xa tawm ntawm cov kav dej. Tsuas yog thaum nws tau lees paub tias ob qho tib si cov qauv thiab kev tiv thaiv - kev ua haujlwm corrosion ua tau raws li qhov yuav tsum tau ua tuaj yeem muab tso rau hauv kev siv.
7. Cov lus xaus
Kev kho cov kav dej galvanized kom raug tsis yog tsuas yog hloov lawv cov duab xwb, tab sis kuj muaj cov txheej txheem kev ua haujlwm ntawm cov khoom siv, tiv thaiv- tiv thaiv corrosion, thiab kev ua haujlwm ntev -. Tsim nyog xaiv txoj kev khoov, tswj lub vojvoog dabtsi yog khoov, siv cov cuab yeej tshaj lij, thiab ua haujlwm zoo hauv kev tiv thaiv kev kho mob tom qab khoov yog cov yuam sij kom ntseeg tau tias lub neej kev pabcuam ntawm cov kav dej galvanized thiab engineering zoo.
Hauv kev tsim kho vaj tse, kev saib xyuas ntau dua rau cov ntsiab lus me me no, kev saib xyuas tsawg dua thiab cov nqi hloov pauv tuaj yeem txo qis, thiab cov kav dej galvanized tuaj yeem ua rau lawv qhov kev ua tau zoo ruaj khov hauv lawv cov haujlwm.
