Taw qhia
Kev tsim cov txheej txheem ntawm cov ntawv hlau galvanized yog lub hauv paus hauv kev lag luam steel, muab cov ntaub ntawv tseem ceeb rau ntau daim ntawv thov xws li kev tsim kho mus rau kev tsim tsheb. Rau factories, distributors, thiab wholesalers, nkag siab txog intricacies ntawm cov txheej txheem no yog ib qho tseem ceeb rau kev ua kom cov khoom zoo thiab ua tau raws li kev lag luam xav tau. Qhov kev ntsuam xyuas dav dav no delves rau hauv cov txheej txheem, cov khoom siv, thiab thev naus laus zis koom nrog hauv kev tsim cov khoom zoo. Galvanized Steel Sheets , tso lub teeb ntawm lawv qhov tseem ceeb hauv kev lag luam niaj hnub no.
Lub hauv paus ntawm Galvanization
Galvanization yog txheej txheem metallurgical uas muaj cov txheej txheem hlau lossis hlau nrog txheej zinc los tiv thaiv corrosion thiab xeb. Cov txheej zinc ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv lub hauv paus hlau los ntawm ib puag ncig xws li ya raws thiab oxygen. Cov txheej txheem no txuas ntxiv lub neej ntawm cov khoom siv hlau thiab txhim kho lawv cov kav ntev, ua cov ntawv hlau galvanized yog cov khoom nyiam hauv ntau qhov kev lag luam.
Keeb Kwm Txheej Txheem
Lub tswv yim ntawm galvanization hnub rov qab mus rau thaum ntxov xyoo pua 19th thaum Luigi Galvani nrhiav tau cov txheej txheem electrochemical uas tam sim no dais nws lub npe. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1830 uas thawj qhov kev siv ntawm galvanization tshwm sim. Cov txheej txheem tau hloov zuj zus txij thaum ntawd los, suav nrog cov thev naus laus zis thiab cov txheej txheem los txhim kho kev ua haujlwm thiab cov khoom zoo.
Cov khoom siv raw thiab cov txheej txheem ua ntej kho
Kev tsim cov nplooj ntawv galvanized steel pib nrog xaiv cov khoom zoo raw khoom. Cov khoom tseem ceeb yog cov ntawv hlau thiab zinc, nrog rau cov purity thiab muaj pes tsawg leeg ntawm ob qho tib si ua lub luag haujlwm tseem ceeb hauv cov khoom kawg qhov kev ua tau zoo.
Kev xaiv hlau
Xaiv cov qib steel zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo galvanization. Cov ntsiab lus xws li cov ntsiab lus carbon, qhov zoo ntawm qhov chaw, thiab cov khoom siv kho tshuab yuav tsum raug txiav txim siab. Tsawg-carbon steel feem ntau yog siv vim nws txoj kev tsim muaj peev xwm zoo heev thiab kev sib raug zoo nrog cov txheej txheem zinc txheej.
Kev npaj nto
Ua ntej galvanization, cov nplooj ntawv steel tau ua tib zoo tu kom tshem tawm cov kab mob xws li roj, av, thiab zeb nplai.
