Galvanizing kab yog cov cuab yeej tsim tshwj xeeb tsim los rau cov txheej txheem galvanizing, uas suav nrog kev siv cov zinc txheej rau hlau lossis hlau los tiv thaiv corrosion. Cov txheej txheem yog qhov tseem ceeb nyob rau hauv ntau yam kev lag luam, suav nrog kev tsim kho, tsheb, thiab kev tsim khoom, qhov twg qhov ntev thiab kav ntev ntawm cov hlau yog qhov tseem ceeb.Galvanizing kabintegrate ntau yam tseem ceeb, nrog rau cov khoom siv tuav thiab flux rov qab thiab regeneration units, los xyuas kom meej ntau lawm.
Galvanizing txheej txheem
Cov txheej txheem galvanizing feem ntau muaj ntau theem, suav nrog kev npaj nto, galvanizing, thiab tom qab kho. Txhua theem yog qhov tseem ceeb rau kev ua tiav ibzoo zinctxheej uas adheres rau lub substrate thiab muab kev tiv thaiv ntev.
1. Kev Npaj Nto: Ua ntej galvanizing steel lossis hlau, nws yuav tsum tau ntxuav kom huv si kom tshem tau cov kab mob xws li xeb, roj lossis av. Qhov no feem ntau yog ua tiav los ntawm kev sib xyaw ua ke ntawm kev tu txhua yam thiab kev kho tshuaj, suav nrog kev khaws cov kua qaub hauv cov kua qaub. Lub hom phiaj yog los tsim kom muaj qhov chaw huv si kom pom qhov adhesion ntawm zinc txheej.
2.Galvanizing: Thaum lub saum npoo yog npaj, cov hlau yog immersed nyob rau hauv ib da dej ntawm molten zinc, feem ntau rhuab mus rau ib ncig ntawm 450 ° C (842 ° F). Cov zinc reacts nrog cov hlau hauv cov hlau los ua cov txheej txheem ntawm zinc-hlau alloy txheej, uas tom qab ntawd them nrog ib txheej ntawm zinc ntshiab. Nws yog qhov no metallurgical daim ntawv cog lus uas muab galvanized steel nws zoo heev corrosion kuj.
3.Post-kev kho mob: Tom qab galvanizing, cov khoom coated tej zaum yuav muaj ntau yam txheej txheem tom qab kho, xws li quenching los yog passivation, los txhim kho kev ua tau zoo ntawm zinc txheej. Cov kev kho mob no tuaj yeem txhim kho cov tsos ntawm galvanized nto thiab ntxiv txhim kho nws cov corrosion kuj.
Lub luag haujlwm ntawm cov khoom siv tuav khoom
Cov khoom siv tuav cov khoom ua si lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm ntawm cov kab galvanizing. Cov cuab yeej no yog lub luag haujlwm rau kev txav, khaws cia thiab tswj cov ntaub ntawv thoob plaws hauv txheej txheem galvanizing. Lub ntsiab hom ntawmkhoom siv tuavsiv nyob rau hauv galvanizing kab muaj xws li:
1.Conveyors: Cov tshuab no txav cov hlau los ntawm ntau theem ntawm cov txheej txheem galvanizing, los ntawm kev npaj nto mus rau lub tank galvanizing. Automated conveyor systems tuaj yeem txo cov nqi zog thiab ua kom ntau lawm ceev.
2.Crane thiab Hoist: Rau qhov loj lossis hnyav dua, cranes thiab hoists yog qhov tseem ceeb rau kev nqa thiab muab cov khoom tso rau hauv kab galvanizing. Cov tshuab no ua kom cov khoom muaj kev nyab xeeb thiab raug muab tso rau hauv lub tank galvanizing thiab lwm qhov chaw ua haujlwm.
3.Storage Racks: Kev khaws cia cov ntaub ntawv raw thiab cov khoom tiav yog qhov tseem ceeb rau kev tswj xyuas qhov chaw tsim khoom thiab ua haujlwm zoo. Cov racks cia pab txhim kho qhov chaw zoo thiab xyuas kom meej tias cov khoom siv tau yooj yim nkag tau thaum xav tau.
Flux recovery thiab regeneration ntaus ntawv
Flux rov qab thiab rov tsim dua tshiab yog ib feem tseem ceeb ntawm cov kab niaj hnub galvanizing. Flux yog ib qho tshuaj sib xyaw siv thaum lub sij hawm txheej txheem galvanizing los txhim kho qhov zoo ntawm zinc txheej. Nws pab tiv thaiv oxidation ntawm cov hlau nto thiab txhawb nqa zoo adhesion ntawm zinc. Txawm li cas los xij, flux tuaj yeem ua paug rau lub sijhawm, ua rau txo qis kev ua haujlwm thiab nce nqi.
Refluxers dawsqhov teeb meem no los ntawm kev tu thiab rov tsim cov tshuaj flux tas li. Cov txheej txheem no muaj ob peb kauj ruam:
1.Filtration: Lim cov dej paug kom tshem tawm cov impurities thiab cov khoom uas yuav cuam tshuam rau qhov zoo ntawm cov txheej txheem galvanizing.
2.Chemical Treatment: Lub lim dej tuaj yeem kho tau tshuaj los kho nws cov khoom thiab kev ua tau zoo. Qhov no yuav suav nrog kev ntxiv cov tshuaj tshwj xeeb kom rov ua kom cov tshuaj flux.
3.Recycling: Cov txheej txheem txheej txheem tuaj yeem rov ua dua thiab rov siv dua hauv cov txheej txheem galvanizing, txo cov khib nyiab thiab txo cov nqi khiav lag luam. Qhov no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm cov kab galvanizing, tab sis kuj tseem pab ua kom tiav cov kev coj ua ntau dua.
Hauv cov ntsiab lus, galvanizing kab yog qhov nyuaj thiab qhov tseem ceeb rau kev tsim cov khoom siv hlau galvanized. Kev koom ua ke ntawmkhoom siv tuavnrog flux rov qab thiab regeneration units txhim kho efficiency, zoo thiab sustainability ntawm cov txheej txheem galvanizing. Raws li kev lag luam thov rau cov khoom siv ruaj khov thiab corrosion-resistant tseem nce ntxiv, qhov tseem ceeb ntawm cov kab galvanizing siab yuav tsuas nce, ua rau lawv yog ib feem tseem ceeb ntawm kev tsim khoom niaj hnub.
