Galvanizing yog txheej txheem ntawm kev thov txheej tiv thaiv ntawm zinc rau cov hlau lossis hlau kom tiv thaiv corrosion. Cov txheej txheem feem ntau siv hauv kev tsim cov kav dej, tshwj xeeb yog cov siv nyob rau hauv ntau yam kev lag luam zoo li kev tsim kho, roj thiab roj av.Galvanizing cov qauv rau kavyog qhov tseem ceeb los ua kom muaj kev ua tau zoo thiab kav dej ruaj khov ntawm galvanized. Cia peb ntsaub mus rau cov ntsiab lus ntawm cov yeeb nkab Galvanizing cov qauv thiab lawv txhais li cas hauv cov yeeb nkab Galvanizing kab.
Yeeb Nkab GalvanizingCov qauv yog tsuas yog tsim los ntawm Asmeskas haiv neeg rau kev sim thiab cov khoom siv (ASTM) cov koom haum thoob ntiaj teb. ASTM teeb cov qauv tshwj xeeb rau cov txheej txheem galvanizing, uas suav nrog cov tuab ntawm galvanized txheej, cov nplaum ntawm txheej, thiab zoo zuag qhia tag nrho ntawm covGalvanizedNto. Cov qauv no tseem ceeb los saib xyuas kev ncaj ncees ntawm galvanized cov yeeb nkab thiab ua kom nws cov kev ua tau zoo hauv ntau cov ntawv thov.
Ib qho ntawm tus qauv tseem ceeb rau galvanized yeeb yog Astm A123 / A123M, uas qhia meej txog cov khoom lag luam galvanized ntawm cov khoom lag luam, suav nrog cov kav dej. Tus qauv no qhia cov txheej txheem luv luv txheej tuab tuab, adhesion thiab ua tiav rau Galvanized cov yeeb nkab. Nws tseem muab cov lus qhia rau kev kuaj thiab kuaj ntawmGalvanized Txheej TxheemTxhawm rau kom ua raws li cov qauv.
In Yeeb Galvanizing kab, Ua raws li ASTM Actm A123 / A123M yog qhov tseem ceeb ua rau tsim cov yeeb nkab zoo galvanized. Cov txheej txheem galvanizing feem ntau cuam tshuam nrog ntau theem, suav nrog kev kho mob rau sab nto, kub-dip galvanizing thiab tom qab ua. Txhua theem yuav tsum ua raws li ASTM cov qauv kom ua tiav cov txheej uas yuav tsum tau ua tuab thiab zoo.
Kev npaj sab saum npoo koom nrog kev ntxuav cov kav dej kom tshem tawm cov xeb, nplai lossis lwm yam kev cuam tshuam uas yuav tiv thaiv covGalvanizingtxheej los ntawm adhering. Kauj ruam no yog qhov tseem ceeb los xyuas kom meej cov adhesion zoo ntawm lubGalvanized Txheejmus rau cov yeeb nkab nto. Tus txheej txheem kub-dip galvanizing galvanizing cov txiv neej cuam tshuam cov kav dej ntxuav hauv tus da dej ntawm molten zinc, uas metallurgically Bonds rau cov hlau los ua cov txheej txheem tiv thaiv.
Tom qab cov txheej txheem galvanizing, cov yeeb nkab yuav yauv ua tom qab, uas yuav suav nrog quenching, passating txheej thiab cov nplaum. Cov kauj ruam no yog qhov tseem ceeb los xyuas kom paub tseeb tias cov yeeb nkab galvanized ua tau raws li cov qauv Astm thiab npaj rau siv ntau cov ntawv thov.
Ua raws liYeeb Nkab GalvanizingCov qauv tsis tsuas yog ua kom zoo thiab ruaj khov ntawm cov yeeb nkab, tab sis kuj ua rau nws txoj kev ua tau zoo thiab corrosion tsis kam. ASTM-Raws Galvanized cov yeeb nkab yog qhov tsim rau sab nraum zoov, High-humity thiab kev faib dej ua ke, kev txhawb nqa cov txheej txheem thiab cov khoom lag luam.
Hauv cov ntsiab lus, cov yeeb nkab galvanizing txhais los ntawm Astm thoob ntiaj teb ua si ib lub luag haujlwm tseem ceeb hauv cov yeeb nkab galvanizing ntau lawm. Ua raws li cov qauv no kom ntseeg tau tiasGalvanized yeeb nkabUa tau raws li qhov yuav tsum tau ua rau cov txheej tuab, adhesion thiab tag nrho. Los ntawm kev ua raws li ASTM cov qauv,manufacturerstuaj yeem tsimCov Khoom Zoo Galvanized Yeeb Nkabuas muab kev tiv thaiv corrosion corrosion thiab kev pabcuam lub neej nyob rau hauv ntau yam kev lag luam thiab kev lag luam.
