Cov kab galvanizing yog cov khoom siv tshwj xeeb tsim rau cov txheej txheem galvanizing, uas muaj kev thov rau cov txheej txheem tuab rau cov hlau lossis hlau kom tiv thaiv corrosion. Cov txheej txheem yog qhov tseem ceeb nyob rau hauv ntau yam kev lag luam, suav nrog kev tsim kho, thiab kev tsim khoom lag luam, thiab kev tsim kho, qhov twg kav hlau yog qhov tseem ceeb.Galvanizing kabSib koom ua ke ntau cov khoom siv tseem ceeb, suav nrog cov khoom tuav cov khoom siv thiab cov khoom noj flux rov qab thiab cov khoom tsim kho kom ntseeg tau.
Galvanizing cov txheej txheem
Feem ntau cov txheej txheem galvanizing feem ntau cuam tshuam nrog ntau theem, suav nrog kev npaj rau saum npoo, galvanizing, thiab kev kho tom qab. Txhua theem yog qhov tseem ceeb rau kev ua tiav aHigh-zoo zincTxheej uas ua rau khov kho kom khov kho rau substrate thiab muab kev tiv thaiv ntev-ntev.
1.Surge Kev Npaj: Ua ntej Galvanizing Steel lossis hlau ua kom huv kom tshem tawm cov kev paug tsis muaj xeb xws li xeb, roj lossis av. Qhov no feem ntau yog ua tiav los ntawm kev sib txuas ntawm kev tu tshuab xws li kev kho tshuaj lom neeg, suav nrog pickling hauv kev daws teeb meem. Lub hom phiaj yog tsim kom huv rau saum npoo rau kev pom zoo tshaj plaws ntawm cov txheej txheej zinc.
2.galvanizing: ib zaug cov npoo tau npaj, cov hlau yog raus hauv da dej ntawm Molten zinc, feem ntau yog rhuab rau 450 ° C (842 ° F). Cov Zinc reacts nrog cov hlau nyob hauv cov hlau los ua ib qho ntawm zinc-hlau alloy txheej, uas yog tom qab ntawd txheej ntawm cov ntshiab zinc. Nws yog qhov kev sib tw metallurgical uas muab galvanized steel nws zoo corrosion.
3.Pos-kho mob: tom qab galvanizing, cov khoom coated yuav dhau cov txheej txheem kev kho mob tom qab, xws li quenching lossis passivation, los txhim kho kev ua haujlwm ntawm zinc txheej. Cov kev kho mob no tuaj yeem txhim kho cov tsos ntawm lub galvanized nto thiab ntxiv txhim kho nws corrosion tsis kam.
Lub luag haujlwm ntawm cov khoom siv cov cuab yeej siv
Cov khoom siv tuav cov khoom ua si lub luag haujlwm tseem ceeb hauv kev ua tau zoo thiab ua haujlwm ntawm cov kab galvanizing. Cov cuab yeej siv no yog lub luag haujlwm rau kev txav, cia thiab tswj cov khoom siv thoob plaws cov txheej txheem galvanizing. Cov hom tseem ceeb ntawmKhoom Siv Khoom Siv Khoom Siv Khoom Sivsiv nyob rau hauv galvanizing kab muaj xws li:
1.Cov cov tshuab no: Cov tshuab no txav cov hlau seem los ntawm cov txheej txheem ntawm cov txheej txheem galvanizing, los ntawm kev npaj saum npoo mus rau galvanizing tank. Rho tawm conveyor tshuab tuaj yeem txo cov nqi ua haujlwm thiab nce ntau lawm ceev.
2.Cra thiab hoist: rau loj dua lossis hnyav dua, cranes thiab hoists yog qhov tseem ceeb rau kev nqa thiab muab cov ntaub ntawv nyob hauv kab galvanizing. Cov kab ke no ua kom cov ntu muaj kev nyab xeeb thiab raug muab tso rau hauv cov galvanizing tso tsheb hlau luam thiab lwm yam chaw ua haujlwm.
3. Kho kom muaj Racks: Qhov tsim nyog cia ntawm raw cov ntaub ntawv thiab cov khoom tiav yog qhov tseem ceeb kom tswj cov txheej txheem thiab cov khoom siv ntau lawm. Cia racks pab ua kom zoo dua qhov chaw thiab kom ntseeg tau tias cov ntaub ntawv tau yooj yim siv tau thaum xav tau.
Flux rov qab thiab tsim khoom dua tshiab
Flux rov qab thiab cov teeb tsa ua ke yog ib feem tseem ceeb ntawm cov kab niaj hnub no. Flux yog cov tshuaj sib txuas tau siv thaum lub galvanizing txheej txheem los txhim kho qhov zoo ntawm zinc txheej. Nws pab tiv thaiv oxidation ntawm hlau nto thiab txhawb nqa zoo dua adhesion ntawm cov zinc. Txawm li cas los xij, flux tuaj yeem dhau mus ua paug rau lub sijhawm, ua kom txo qis kev ua haujlwm thiab nce nqi.
Refluxers DawsQhov teeb meem no los ntawm kev tu txuas ntxiv thiab rov ua dua cov tshuaj flux flux. Tus txheej txheem no suav nrog ntau kauj ruam:
1.Filtration: lim cov khoom tsis huv kom tshem impurities thiab hais uas tuaj yeem cuam tshuam qhov zoo ntawm cov txheej txheem galvanizing.
2. DiCemical kev kho: lub lim flux tuaj yeem siv tshuaj kho tshuaj kho kom rov kho nws cov khoom thiab ua tau zoo. Qhov no tuaj yeem koom nrog kev ntxiv cov tshuaj tshwj xeeb rau kev thim rov qab cov tshuaj flux.
3. Rov ua kom zoo: Cov txheej txheem flux tuaj yeem rov ua dua tshiab thiab siv cov txheej txheem galvanizing, txo cov nqi thiab txo qis kev ua haujlwm. Qhov no tsis tsuas yog txhim kho kev ua tau zoo ntawm cov kab galvanizing, tab sis kuj tseem yuav pab ua tiav ntau dua cov kev ua haujlwm.
Hauv cov ntsiab lus, cov kab galvanizing yog cov khoom thiab cov chaw tseem ceeb rau kev tsim cov khoom galvanized steelized. Kev sib koom ua ke ntawmKhoom Siv Khoom Siv Khoom Siv Khoom SivNrog flux rov qab thiab rov tsim dua tshiab unsits txhim kho kev ua tau zoo, zoo thiab muaj kev ruaj ntseg ntawm cov txheej txheem galvanizing. Raws li kev lag luam xav tau cov ntaub ntawv ruaj khov thiab kho kom loj dua, qhov tseem ceeb ntawm Galvanizing cov kab siab yuav nce ntxiv, ua rau lawv ib feem tseem ceeb ntawm kev tsim khoom niaj hnub.
