Cov yam ntxwv
1. Kev tiv thaiv ob npaug ntawm cov txheej zinc:
Ib txheej hlau-zinc alloy ntom ntom (lub zog sib txuas muaj zog) thiab ib txheej zinc ntshiab tau tsim rau ntawm qhov chaw, cais cov huab cua thiab cov dej noo, ua rau qeeb heev rau qhov xeb ntawm cov kav hlau.
2. Kev tiv thaiv anode sacrificial:
Txawm tias cov txheej txheem puas tsuaj ib nrab, zinc yuav xeb ua ntej (kev tiv thaiv electrochemical), tiv thaiv cov hlau substrate los ntawm kev yaig.
3. Lub neej ntev:
Hauv ib puag ncig ib txwm muaj, lub neej ua haujlwm tuaj yeem ncav cuag 20-30 xyoo, uas ntev dua li cov kav hlau ib txwm muaj (xws li lub neej ntawm cov kav dej pleev xim yog li 3-5 xyoos).
Tiv Tauj Peb Kom Paub Ntxiv Txog Cov Kav Hlau Galvanized.
Kub-dipyeeb nkab galvanizedCov kav dej siv dav hauv kev tsim kho vaj tse (xws li lub Hoobkas trusses, scaffolding), kev tsim kho hauv nroog (guardrails, txoj kev teeb pom kev zoo, cov kav dej ntws), lub zog thiab lub zog (cov pej thuam kis, photovoltaic brackets), cov chaw ua liaj ua teb (tsev cog khoom cog qoob loo, cov tshuab dej), kev tsim khoom lag luam (txee, cov kav dej cua) thiab lwm yam vim lawv qhov kev tiv thaiv corrosion zoo heev, lub zog siab thiab lub neej ntev. Lawv muab kev tiv thaiv tsis tas yuav saib xyuas, pheej yig thiab txhim khu kev qha hauv sab nraum zoov, av noo lossis corrosive ib puag ncig nrog lub neej ua haujlwm txog li 20-30 xyoo. Lawv yog cov tshuaj tiv thaiv corrosion nyiam los hloov cov kav hlau ib txwm muaj.
Cov txheej txheem tsim khoom rau cov kav dej galvanized welded ua raws li cov kauj ruam no:
1. Kev kho cov khoom siv raw ua ntej: Xaiv cov kauj hlau uas muaj cov pa roj carbon tsawg, txiav ua tej daim uas dav txaus, muab ntsev kom tshem tawm cov nplai, yaug nrog dej huv, thiab ziab kom tsis txhob xeb.
2. Kev Tsim thiab Kev VuamCov hlau strips raug pub rau hauv lub roller press thiab maj mam dov rau hauv cov raj billets puag ncig. Lub tshuab vuam zaus siab yaj cov kab sib txuas ntawm cov raj billet thiab nias thiab ua kom nruj, tsim cov raj puag ncig dub. Tom qab txias dej, cov raj raug ntsuas qhov loj thiab kho, thiab tom qab ntawd txiav kom ntev raws li qhov xav tau.
3. Kev Ua Kub Dias Ntawm Qhov Chaw(galvanizing tuaj yeem muab faib ua kub-dip galvanizing (kub-dip galvanizing) thiab txias-dip galvanizing (electrogalvanizing), nrog kub-dip galvanizing yog txoj hauv kev tseem ceeb hauv kev lag luam (nws muab cov txiaj ntsig zoo dua los tiv thaiv xeb)): Cov kav dej welded raug pickling thib ob kom tshem tawm cov khoom tsis huv, raug dipped hauv galvanizing flux, thiab tom qab ntawd kub-dipped hauv molten zinc ntawm 440-460 ° C los ua ib txheej zinc alloy. Cov zinc ntau dhau raug tshem tawm nrog rab riam cua, thiab tom qab ntawd txias. (Cold-dip galvanizing yog ib txheej zinc electrodeposited thiab tsis tshua siv.)
4. Kev Tshuaj Xyuas thiab Ntim KhoomXyuas seb cov txheej zinc thiab qhov loj me ntawm cov zinc zoo li cas, ntsuas seb cov khoom puas lo thiab tsis yooj yim xeb, muab cov khoom uas tsim nyog faib ua pawg thiab muab ntim rau hauv lub thawv cia, thiab muab cov ntawv lo rau.
Cov txheej txheem tsim khoom rau cov kav dej galvanized seamless ua raws li cov kauj ruam no:
1. Kev kho ua ntej ntawm cov khoom siv rawCov hlau tsis muaj qhov sib txuas (feem ntau yog cov hlau uas muaj cov pa roj carbon tsawg) raug xaiv, txiav ua tej qhov ntev uas ruaj khov, thiab tshem tawm cov oxide thiab cov khoom tsis huv ntawm qhov chaw. Tom qab ntawd cov hlau billets raug cua sov kom sov rau qhov kub uas tsim nyog rau kev tho.
2. Kev tho qhov: Cov billets uas tau cua sov raug dov rau hauv cov raj khoob los ntawm lub tshuab zeb tho. Cov raj ces raug dhau los ntawm lub tshuab zeb dov raj kom kho qhov tuab ntawm phab ntsa thiab qhov puag ncig. Lub cheeb tsam sab nraud ces raug kho los ntawm lub tshuab zeb sizing kom ua cov raj dub tsis muaj qhov txuas. Tom qab txias, cov raj raug txiav kom ntev.
3. Kev kho kom zoo nkaujCov raj dub uas tsis muaj qhov sib txuas raug kho kom tshem tawm cov txheej oxide. Tom qab ntawd lawv raug ntxuav nrog dej thiab muab tso rau hauv tus neeg sawv cev galvanizing. Tom qab ntawd lawv raug muab tso rau hauv 440-460 ° C molten zinc los ua ib txheej zinc-hlau alloy. Cov zinc ntau dhau raug tshem tawm nrog rab riam cua, thiab cov raj raug txias. (Kev galvanizing txias yog ib qho txheej txheem electrodeposition thiab tsis tshua siv.)
4. Kev Tshuaj Xyuas thiab Ntim Khoom: Kev sib npaug thiab kev nplaum ntawm cov txheej zinc raug tshuaj xyuas, nrog rau qhov loj ntawm cov kav dej. Cov kav dej uas tau pom zoo ces raug xaiv, muab ntim ua ke, muab daim ntawv lo, thiab khaws cia kom ntseeg tau tias lawv ua tau raws li cov qauv kev tiv thaiv xeb thiab kev ua haujlwm ntawm lub tshuab.
Cov txheej txheem thauj khoom rau cov khoom suav nrog kev thauj mus los ntawm txoj kev, tsheb ciav hlau, dej hiav txwv, lossis ntau hom, raws li cov neeg siv khoom xav tau.
Kev thauj mus los ntawm txoj kev, siv cov tsheb thauj khoom (piv txwv li, cov tsheb thauj khoom tiaj tiaj), muaj kev ywj pheej rau qhov kev ncua luv-nruab nrab, ua rau kev xa khoom ncaj qha mus rau qhov chaw/tsev rau khoom nrog kev thauj khoom/tso tawm yooj yim, zoo tagnrho rau cov xaj me me lossis ceev tab sis kim heev rau qhov kev ncua deb ntev.
Kev thauj mus los ntawm tsheb ciav hlau vam khom cov tsheb ciav hlau thauj khoom (piv txwv li, cov tsheb thauj khoom uas muaj hau/qhib nrog cov hlua khi uas tiv tau nag), tsim nyog rau kev thauj khoom mus deb, ntim ntau nrog tus nqi qis thiab kev ntseeg siab siab, tab sis xav tau kev thauj mus los luv luv.
Kev thauj mus los hauv dej (hauv av/dej hiav txwv) los ntawm cov nkoj thauj khoom (piv txwv li, cov nkoj loj/thawv) muaj tus nqi qis heev, haum rau kev thauj mus los deb, ntim ntau ntawm ntug dej hiav txwv/dej, tab sis nws txwv rau chaw nres nkoj/kev thiab qeeb.
Kev thauj mus los ntau hom (piv txwv li, tsheb ciav hlau + txoj kev, hiav txwv + kev) sib npaug tus nqi thiab lub sijhawm, tsim nyog rau kev txiav txim hla cheeb tsam, kev deb, qhov rooj-rau-qhov rooj muaj nqis siab.
