Kev pleev xim galvanizing yog ib qho txheej txheem ntawm kev siv ib txheej tiv thaiv ntawm zinc rau hlau lossis hlau kom tiv thaiv kev xeb. Cov txheej txheem no feem ntau siv rau hauv kev tsim cov kav dej, tshwj xeeb tshaj yog cov uas siv rau hauv ntau yam lag luam xws li kev tsim kho, roj thiab roj av, thiab kev muab dej.Cov qauv Galvanizing rau cov kav dejyog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov kav dej galvanized zoo thiab ruaj khov. Cia peb kawm txog cov ntsiab lus ntawm cov qauv galvanizing yeeb nkab thiab lawv txhais li cas hauv cov kab galvanizing yeeb nkab.
Kev sib txuas ntawm cov yeeb nkabcov qauv feem ntau yog teeb tsa los ntawm American Society for Testing and Materials (ASTM) lub koom haum thoob ntiaj teb. ASTM teeb tsa cov qauv tshwj xeeb rau cov txheej txheem galvanizing, uas suav nrog qhov tuab ntawm cov txheej galvanized, qhov lo ntawm cov txheej, thiab qhov zoo tag nrho ntawmgalvanizednto. Cov qauv no yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees ntawm cov yeeb nkab galvanized thiab xyuas kom meej tias nws ua tau zoo hauv ntau yam kev siv.
Ib qho ntawm cov qauv tseem ceeb rau cov yeeb nkab galvanized yog ASTM A123/A123M, uas qhia meej txog cov kev cai rau cov txheej galvanized ntawm cov khoom hlau, suav nrog cov yeeb nkab. Cov qauv no qhia txog qhov tsawg kawg nkaus ntawm cov txheej tuab, kev nplaum thiab kev ua tiav rau cov yeeb nkab galvanized. Nws kuj muab cov lus qhia rau kev tshuaj xyuas thiab kev sim ntawmcov txheej txheem galvanizedkom ntseeg tau tias ua raws li cov qauv.
In cov yeeb nkab galvanizing kab, kev ua raws li ASTM A123/A123M cov qauv yog qhov tseem ceeb rau kev tsim cov yeeb nkab galvanized zoo. Cov txheej txheem galvanizing feem ntau muaj ntau theem, suav nrog kev kho qhov chaw, kub-dip galvanizing thiab tom qab ua tiav. Txhua theem yuav tsum ua raws li ASTM cov qauv kom ua tiav qhov tuab thiab zoo ntawm txheej.
Kev npaj nto suav nrog kev ntxuav cov kav dej kom tshem tawm cov xeb, nplai lossis lwm yam tsis huv uas yuav tiv thaiv taukev pleev xim galvanizingtxheej los ntawm kev lo rau. Kauj ruam no yog qhov tseem ceeb kom ntseeg tau tias muaj kev lo rau zoo ntawmtxheej galvanizedrau ntawm qhov chaw ntawm cov yeeb nkab. Cov txheej txheem galvanizing kub-dip suav nrog kev muab cov yeeb nkab ntxuav rau hauv ib lub dab da dej ntawm cov zinc molten, uas metallurgically bonds rau cov hlau los tsim ib txheej tiv thaiv..
Tom qab ua tiav cov txheej txheem galvanizing, cov yeeb nkab yuav raug ua tiav tom qab, uas yuav suav nrog kev quenching, passivation lossis kuaj xyuas qhov tuab ntawm txheej thiab kev nplaum. Cov kauj ruam tom qab ua tiav no yog qhov tseem ceeb los xyuas kom meej tias cov yeeb nkab galvanized ua tau raws li cov kev cai ntawm ASTM cov qauv thiab npaj siv rau ntau yam kev siv.
Ua raws likev pleev xim rau cov yeeb nkabcov qauv tsis yog tsuas yog ua kom cov yeeb nkab zoo thiab ruaj khov xwb, tab sis kuj pab txhawb rau nws txoj kev ua haujlwm ntev thiab kev tiv thaiv xeb. Cov yeeb nkab galvanized ASTM-raws li qhov tsim nyog rau sab nraum zoov, muaj av noo ntau thiab muaj xeb, ua rau nws zoo tagnrho rau cov ntawv thov xws li kev faib dej, kev txhawb nqa cov qauv thiab cov kav dej kev lag luam.
Hauv kev xaus, cov qauv galvanizing yeeb nkab uas ASTM International txhais ua lub luag haujlwm tseem ceeb hauv cov kab ntau lawm galvanizing yeeb nkab. Kev ua raws li cov qauv no ua kom ntseeg tau tiasyeeb nkab galvanizedua tau raws li qhov yuav tsum tau ua rau cov txheej tuab, kev nplaum thiab qhov zoo tag nrho. Los ntawm kev ua raws li cov qauv ASTM,cov chaw tsim khoomtuaj yeem tsim taucov yeeb nkab galvanized zoouas muab kev tiv thaiv xeb zoo tshaj plaws thiab lub neej ua haujlwm hauv ntau yam kev lag luam thiab kev lag luam.
