To taub lub luag hauj lwm ntawm aGalvanizing cogthiab qhov tseem ceeb ntawm Galvanizing lauj kaub hauv cov txheej txheem tsim khoom
Hauv thaj tsam ntawm kev kho hlau thiab kev tiv thaiv, galvanization plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv hlau thiab cov khoom siv hlau ntev ntev. Ib lub tuam txhab suav galvanizing khoom tsim tshwj xeeb hauv kev tsim cov lauj kaub zoo galvanizing thiab lwm yam khoom siv tseem ceeb uas pab txhawb txoj haujlwm no. Txhawm rau kom txaus siab rau qhov tseem ceeb ntawm cov khoom no, nws yog ib qho tseem ceeb kom nkag siab tias cov nroj tsuag galvanizing ua li cas thiab cov xwm txheej tshwj xeeb uas nws ua haujlwm, tshwj xeeb tshaj yog hais txog qhov kub ntawm lub lauj kaub galvanizing.
Galvanizing tsob nroj ua dab tsi?
Lub galvanizing cog yog feem ntau koom nrog hauv cov txheej txheem ntawm galvanization, uas yog daim ntawv thov kev tiv thaiv.zinctxheej rau hlau los yog hlau kom tiv thaiv xeb. Cov txheej txheem no yog qhov tseem ceeb hauv ntau yam kev lag luam, suav nrog kev tsim kho, tsheb, thiab kev tsim khoom, qhov twg cov khoom siv hlau raug cuam tshuam rau ib puag ncig hnyav.
Cov txheej txheem galvanization feem ntau muaj ob peb kauj ruam tseem ceeb:
Kev Npaj Nto: Ua ntej qhov tseeb galvanization tuaj yeem tshwm sim, cov hlau saum npoo yuav tsum tau ntxuav kom huv si kom tshem tawm cov kab mob xws li roj, roj, av, lossis xeb. Qhov no feem ntau yog ua tiav los ntawm ntau cov tshuaj da dej, suav nrog degreasing thiab pickling daws.
Fluxing: Tom qab ntxuav, cov hlau raug kho nrog cov tshuaj flux, uas pab tiv thaiv oxidation thiab ua kom zoo dua adhesion ntawm zinc txheej.
Galvanizing: Cov hlau npaj tau muab tso rau hauv agalvanizing lauj kaubpuv nrog molten zinc. Qhov no yog qhov tseeb txheej txheej tshwm sim, raws li zinc bonds nrog cov hlau los yog hlau los tsim ib txheej tiv thaiv.
Txias thiab tshuaj xyuas: Thaum lub galvanization tiav, cov hlau coated raug tshem tawm ntawm lub lauj kaub thiab tso cai rau txias. Tom qab ntawd nws raug tshuaj xyuas kom muaj kev ruaj ntseg zoo los xyuas kom meej tias cov txheej txheem zoo ib yam thiab ua tau raws li cov qauv kev lag luam.
Kev Kho Mob Tom Qab: Hauv qee kis, kev kho mob ntxiv tuaj yeem siv los txhim kho cov khoom ntawm galvanized nto, xws li passivation lossis pleev xim.
Lub luag haujlwm ntawm Galvanizing lauj kaub
Hauv plawv ntawm cov txheej txheem galvanization yog lub lauj kaub galvanizing, ib qho tseem ceeb ntawm cov khoom uas tuav cov zinc molten. Kev tsim thiab kev tsim kho ntawm lub lauj kaub galvanizing yog qhov tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm ntawm cov txheej txheem galvanization. Ib lub tuam txhab suav galvanizing cov cuab yeej tsim khoom feem ntau tsom rau kev tsim cov lauj kaub zoo galvanizing uas tuaj yeem tiv taus cov xwm txheej huab cua ntawm cov txheej txheem galvanization.
Temperature yog dab tsi aGalvanizing lauj kaub?
Qhov kub ntawm lub lauj kaub galvanizing yog ib qho tseem ceeb ntawm cov txheej txheem galvanization. Feem ntau, cov zinc molten hauv lub lauj kaub yog khaws cia ntawm qhov kub ntawm 450 ° C txog 460 ° C (kwv yees li 842 ° F txog 860 ° F). Qhov ntsuas kub no yog qhov tseem ceeb rau ntau qhov laj thawj:
Zinc Fluidity: Ntawm qhov kub siab no, zinc tseem nyob hauv lub xeev ua kua, tso cai rau yooj yim raus dej ntawm cov khoom hlau. Lub fluidity ntawm molten zinc xyuas kom meej tias nws tuaj yeem ntws mus rau txhua qhov crevices thiab muab cov txheej txheem sib xws.
Tshuaj tiv thaiv: Qhov kub thiab txias ua kom yooj yim rau cov tshuaj tiv thaiv ntawm zinc thiab hlau los yog hlau, tsim ib daim ntawv cog lus metallurgical uas txhim kho cov kav ntev ntawm cov txheej. Daim ntawv cog lus no yog qhov tseem ceeb rau kev tiv thaiv ntev ntawm cov hlau tiv thaiv corrosion.
Kev ua tau zoo: Kev tuav lub lauj kaub galvanizing ntawm qhov kub thiab txias kom ntseeg tau tias cov txheej txheem ua haujlwm tau zoo, txo lub sijhawm kom cov hlau yuav tsum tau coated txaus. Qhov kev ua tau zoo no yog qhov tseem ceeb rau kev ua kom tau raws li qhov xav tau ntau lawm hauv qhov chaw tsim khoom sai.
Kev Tswj Xyuas Zoo:Kev tswj qhov kub thiab txias nyob rau hauv lub lauj kaub galvanizing yog qhov tseem ceeb rau kev ruaj ntseg zoo. Kev hloov pauv ntawm qhov kub thiab txias tuaj yeem ua rau muaj qhov tsis xws ntawm cov txheej txheej, xws li cov tuab tsis sib xws lossis tsis zoo adhesion, uas tuaj yeem cuam tshuam qhov kev tiv thaiv zoo ntawm galvanized nto.
Qhov tseem ceeb ntawm cov cuab yeej zoo
Qhov zoo ntawm lub lauj kaub galvanizing thiab lwm yam khoom siv ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov txheej txheem galvanization. Cov lauj kaub zoo yog tsim los tiv thaiv qhov corrosive ntawm molten zinc thiab cov kub kub cuam tshuam, ua kom lub neej ntev thiab kev ntseeg tau.
Tsis tas li ntawd, kev nce qib hauv thev naus laus zis tau ua rau kev txhim kho cov txheej txheem ua haujlwm zoo dua thiab zoo ib puag ncig galvanizing. Niaj hnub nimno galvanizing pots yuav suav nrog cov yam ntxwv xws li kev tswj qhov kub thiab txias, kev siv lub tshuab ua haujlwm tsis siv neeg, thiab txhim kho kev rwb thaiv tsev kom txhim khu lub zog thiab txo cov nqi ua haujlwm.
