Qhov Tseem Ceeb Qhov txawv - Galvanized Yeeb Nkab VS Cov Khoom Siv Hluav Taws Xob
Iron yog cov hlau uas siv los tsim cov khoom sib txawv. Nws yog dav siv vim nws cov yam ntxwv zoo. Txawm li cas los xij, muaj qee cov khoom tsis zoo thiab. Cov yam ntxwv tsis zoo no txwv kev siv hlau ua hlau. Yog li ntawd, peb xav tau txoj hauv kev los tshem tawm cov khoom tsis zoo no. Galvanization yog ib txoj kev uas siv los tiv thaiv hlau los ntawm xeb. Cov kav dej tuaj yeem galvanized txhawm rau tiv thaiv xeb. Ductile cam khwb cia hlau yog lwm txoj hauv kev muab cov khoom tsim nyog rau hlau. Qhov no yog ua kom cov hlau hloov tau yooj yim thiab elastic. Qhov sib txawv tseem ceeb ntawm cov yeeb nkab galvanized thiab ductile cam khwb cia hlau yog cov kav dej galvanized yog tsim los ntawm kev siv cov zinc txheej los npog cov kav dej hos cov hlau cam khwb cia yog tsim los ntawm kev sib xyaw graphite nrog hlau.
Dab tsi yog Galvanized yeeb nkab?
Galvanized kav yog cov kav hlau uas yog coated nrog zinc txheej. Cov txheej txheem uas siv los ua cov yeeb nkab galvanized yog hu ua galvanization. Galvanization yog txheej txheem ntawm kev siv cov zinc txheej tiv thaiv rau cov hlau lossis hlau los tiv thaiv cov hlau los ntawm xeb.
Cov txheej txheem ntawm kev tsim cov yeeb nkab galvanized suav nrog kub-dip galvanization, thermal diffusion galvanizing thiab electrochemical txoj kev. Txoj kev zoo tshaj plaws thiab raug nqi yog kub-dip galvanization. Ntawm no, cov yeeb nkab yog submerged nyob rau hauv ib da dej kub ntawm molten zinc. Tom qab muab cov yeeb nkab tawm ntawm lub da dej, ib txheej zinc tau tso rau ntawm qhov chaw ntawm cov yeeb nkab. Cov txheej zinc no ua raws li cov txheej txheem tiv thaiv.
zinc txheej ua raws li kev txi anode. Txawm hais tias cov txheej yog khawb, cov hlau raug rau saum npoo ntawm cov yeeb nkab yog tiv thaiv los ntawm cov zinc txheej ntxiv.
Daim duab 01: Galvanized Pipes
Galvanized kav yog siv rau kev faib cov dej kho. Cov dej kho tau yog dej haus. Cov dej kho no yuav tsum tsis txhob muaj kab mob los ntawm xeb. Yog li ntawd, galvanized yeeb nkab yog ib qho kev xaiv zoo rau lub hom phiaj no.
Ductile Cast Iron yog dab tsi?
Cov cam khwb cia hlau yog ib hom cam khwb cia hlau ua los ntawm kev ntxiv graphite. Cam khwb cia hlau yog tsim los ntawm cua sov hlau kom yaj, thiab cov hlau molten no yog poured rau hauv pwm kom solidify. Cam khwb cia hlau yog tsim los ntawm hlau, silicon thiab ib tug me me ntawm carbon. Tab sis cam khwb cia hlau yog nplua nuj nyob rau hauv graphite.
Brittleness yog ib qho teeb meem nrog ntau hom cam khwb cia hlau. Tab sis ductile cam khwb cia hlau yog yooj yim heev thiab elastic. Cov khoom ntawm cov cam khwb cia hlau tuaj yeem tswj tau los ntawm kev tswj cov graphite ntxiv rau cov hlau. Nws tuaj yeem sib txawv ntawm 3-60%.

Carbon ntxiv rau hauv daim ntawv ntawm nodular graphite suav nrog. Qhov no txhais tau hais tias graphite yog tam sim no nyob rau hauv ductile cam khwb cia hlau nyob rau hauv daim ntawv ntawm nodules es tsis ua kom tiav mixing los yog striated qauv. Cov nodules sib npaug inhibit qhov tsim ntawm cov kab nrib pleb. Yog li, cov duab kheej kheej ntawm graphite nyob rau hauv cov hlau cam khwb cia ua rau kev txhim kho ductility thiab cuam tshuam lub zog.
Dab tsi yog qhov txawv ntawm Galvanized Yeeb Nkab thiab Cov Hlau Casting?

Summary – Galvanized Pipe vs Ductile Cast Iron
Galvanized yeeb nkab thiab ductile cam khwb cia hlau tuaj yeem piav qhia ua ob hom hlau. Galvanized kav yog cov kav dej uas yog tsim los ntawm txheej txheej hlau nrog zinc txheej. Qhov no tiv thaiv cov kav dej los ntawm xeb. Ductile cam khwb cia hlau yog tsim los ntawm kev ntxiv graphite rau hlau nyob rau hauv daim ntawv ntawm nodular graphite inclusions. Nws ua rau cov hlau ntau dua. Qhov no yog qhov sib txawv tseem ceeb ntawm cov kav dej galvanized thiab cov cam khwb cia hlau.
