Nta
1.Ob chav tiv thaiv zinc txheej:
Ib txheej txheej hlau-zinc alloy (muaj zog sib txuas) thiab cov zinc txheej ntshiab yog tsim rau ntawm qhov chaw, cais cov huab cua thiab noo noo, ncua kev xeb ntawm cov kav hlau.
2.Sacrificial anode tiv thaiv:
Txawm hais tias cov txheej txheej yog ib feem puas, zinc yuav corrode ua ntej (electrochemical tiv thaiv), tiv thaiv cov hlau substrate los ntawm yaig.
3. Lub neej ntev:
Nyob rau hauv ib puag ncig ib puag ncig, kev pabcuam lub neej tuaj yeem ncav cuag 20-30 xyoo, uas ntev dua li cov kav hlau zoo tib yam (xws li lub neej ntawm cov kav dej pleev xim yog li 3-5 xyoos).
Tiv tauj peb kom paub meej ntxiv ntawm Galvanized Steel Pipes.
Kub-dipgalvanized yeeb nkabs yog dav siv nyob rau hauv lub tsev tsim (xws li Hoobkas trusses, scaffolding), municipal engineering (guardrails, txoj kev teeb ncej, cov kav dej), lub zog thiab lub zog (siv yees, photovoltaic brackets), cov chaw ua liaj ua teb (tsev cog khoom skeletons, irrigation systems), industrial manufacturing (rooj, ventilation ducts) thiab lwm yam kev ua neej ntev. Lawv muab kev saib xyuas tsis pub dawb, tus nqi qis thiab kev tiv thaiv kev ntseeg siab nyob rau sab nraum zoov, ntub dej lossis corrosive ib puag ncig nrog lub neej ua haujlwm txog li 20-30 xyoo. Lawv yog cov nyiam los tiv thaiv corrosion los hloov cov kav hlau zoo tib yam.
Cov txheej txheem tsim khoom rau galvanized round welded kav raws li cov kauj ruam no:
1. Raw khoom Pretreatment: Xaiv cov coils uas tsis tshua muaj carbon steel, txiav rau hauv ib daim hlab ntawm qhov dav dav, pickled kom tshem tawm nplai, yaug nrog dej huv, thiab qhuav kom tsis txhob xeb.
2. Tsim thiab Vuam: Cov hlau strips yog pub rau hauv ib lub xovxwm rau cov menyuam thiab maj mam dov mus rau hauv cov raj xa dej. Lub tshuab vuam ntau zaus melts lub raj billet seams thiab squeezes thiab compacts lawv, tsim ib tug dub-skinned round raj. Tom qab dej txias, cov hlab yog qhov loj thiab kho, thiab txiav kom ntev raws li qhov xav tau.
3. Nto Galvanizing(galvanizing tuaj yeem muab faib ua kub-dip galvanizing (kub-dip galvanizing) thiab txias-dip galvanizing (electrogalvanizing), nrog kub-dip galvanizing yog cov txheej txheem tseem ceeb hauv kev lag luam (nws muaj kev tiv thaiv xeb zoo dua)): Cov kav dej welded tau dhau los ua ib qho kev xaiv thib ob kom tshem tawm cov impurities, yog tom qab ntawd kub-dip galvanizing ntawm zinc molecule. 440-460 ° C los tsim zinc alloy txheej. Tshaj zinc raug tshem tawm nrog rab riam cua, thiab tom qab ntawd txias. (Cold-dip galvanizing yog txheej txheej electrodeposited zinc thiab tsis tshua siv.)
4. Kev tshuaj xyuas thiab ntim: Txheeb xyuas cov zinc txheej thiab qhov loj me, ntsuas qhov adhesion thiab corrosion kuj, cais thiab ntim cov khoom tsim nyog, thiab muab tso rau hauv cov ntawv sau cia.
Cov txheej txheem tsim khoom rau galvanized seamless round kav raws li cov kauj ruam no:
1. Raw Khoom Pretreatment: Seamless steel billets (feem ntau yog cov pa roj carbon tsawg) raug xaiv, txiav rau hauv qhov ntev, thiab cov nplai oxide thiab impurities raug tshem tawm. Tom qab ntawd cov billets yog rhuab mus rau qhov kub uas tsim nyog rau kev tho.
2. Piercing: Cov rhuab billets yog dov mus rau hauv cov hlab hollow los ntawm ib tug tho zeb. Cov hlab yog tom qab ntawd dhau los ntawm lub raj dov zeb los kho cov phab ntsa thickness thiab roundness. Sab nraud txoj kab uas hla yog ces kho los ntawm ib tug sizing zeb los tsim txheem seamless dub hlab. Tom qab txias, cov hlab yog txiav kom ntev.
3. Galvanizing: Cov hlab dub seamless tau txais kev kho mob thib ob kom tshem tawm cov oxide txheej. Tom qab ntawd lawv tau rinsed nrog dej thiab dipped nyob rau hauv ib tug galvanizing tus neeg sawv cev. Tom qab ntawd lawv muab tso rau hauv 440-460 ° C molten zinc los ua zinc-hlau alloy txheej. Tshaj zinc raug tshem tawm nrog rab riam cua, thiab cov hlab yog txias. (Cold galvanizing yog txheej txheem electrodeposition thiab tsis tshua siv.)
4. Kev tshuaj xyuas thiab ntim: Lub uniformity thiab adhesion ntawm zinc txheej raug tshuaj xyuas, nrog rau qhov ntev ntawm cov kav dej. Cov kav dej tso cai tom qab ntawd raug txheeb xyuas, ntim, sau npe, thiab khaws cia kom ntseeg tau tias lawv ua tau raws li kev tiv thaiv xeb thiab cov qauv kev ua haujlwm zoo.
Kev thauj mus los rau cov khoom muaj xws li kev tsheb ciav hlau, kev tsheb ciav hlau, hiav txwv, lossis kev thauj mus los ntau yam, raws li cov neeg siv khoom xav tau.
Kev thauj mus los, siv cov tsheb thauj khoom (piv txwv li, flatbeds), hloov tau yooj yim rau kev ncua luv-nruab nrab, ua rau kev xa ncaj qha mus rau qhov chaw / warehouses nrog kev thauj khoom yooj yim / tshem tawm, zoo tagnrho rau kev txiav txim me me los yog ceev tab sis raug nqi mus ntev.
Kev thauj mus los ntawm Rail cia siab rau cov tsheb ciav hlau thauj khoom (piv txwv li, them / qhib wagons nrog rainproof strapping), haum rau kev thauj mus los ntev, ntim loj nrog cov nqi qis thiab kev ntseeg siab, tab sis xav tau kev thauj mus los luv.
Kev thauj dej (hauv av / hiav txwv) los ntawm cov nkoj thauj khoom (piv txwv li, cov nkoj loj / thawv ntim khoom) muaj cov nqi qis, haum rau qhov ntev, ntim loj ntawm ntug hiav txwv / dej hiav txwv, tab sis yog qhov chaw nres nkoj / txoj kev txwv thiab qeeb.
Multimodal thauj (piv txwv li, tsheb ciav hlau + txoj kev, hiav txwv + txoj kev) sib npaug nqi thiab raws sij hawm, haum rau kev sib tw hauv cheeb tsam, kev ncua deb, qhov rooj-rau-qhov rooj uas muaj nqi siab.
