Qhov sib txawv tseem ceeb ntawm zintec thiab galvanized yog cov khoom zintec yog tsim los ntawm electrolysis whereas galvanized khoom yog tsim los ntawm submerging nyob rau hauv ib tug molten zinc da dej.
Cov ntsiab lus zintec thiab galvanized tuaj nyob rau hauv qeb ntawm cov hlau. Ob qho no yog cov txheej txheem uas peb tuaj yeem siv los ua ib txheej nyias ntawm cov hlau, uas pab tiv thaiv corrosion. Ob txoj kev no koom nrog kev siv cov txheej zinc nyias ntawm cov hlau. Txawm li cas los xij, lawv siv ntau txoj hauv kev rau daim ntawv thov.
Zintec yog dab tsi?
Zintec yog ib qho txheej txheem uas peb tuaj yeem siv los ua cov zinc txheej nyias ntawm cov khoom hlau los ntawm txoj kev electrolytic. Lub zinc txheej yog siv los ntawm electrolysis. Yog li ntawd, peb tuaj yeem hu ua zinc plating. Zintec yog lub npe lag luam.
Cov txheej zinc nyias tuaj yeem tiv thaiv cov hlau tiv thaiv corrosion. Cov txheej txheem no yog ib qho tseem ceeb thaum peb xav tau ib txheej nyias ntawm zinc los siv rau ntawm qhov chaw. E.g. nyob rau hauv kev lag luam tsheb, peb yuav tsum tau siv ib co ntxiv decorating coatings ntawm cov xim ntawm cov hlau nto. Ntawm no, cov txheej txheem zintec yog siv; electrogalvanizing.
Yog tias peb cov khoom lag luam yog cov khoom lag luam me me, cov no feem ntau yog ua los ntawm cov ntawv txias dov los yog coiled me me steel. Vim tias tsis tshua muaj malleability thiab tus nqi qis, nws tau dhau los ua cov hlau siv ntau tshaj plaws hauv qee qhov kev lag luam. Txawm li cas los xij, cov hlau alloy no tsis tshua muaj kev cuam tshuam rau corrosion. Nyob rau hauv cov ntaub ntawv no, zintec txoj kev yog ib qho tseem ceeb txheej txheem txij li thaum ib txoj kev xws li kub-dip galvanization tsis tuaj yeem siv. Cov txheej txheem no yuav muab cov hlau nto nrog cov zinc txheej nyias ntawm li 10-175 microns tuab. Yog li, qhov no muab matt grey tiav, uas yog qhov sib txawv ntawm qhov zoo li yav dhau los ntawm cov hlau me me.
Ntxiv mus, txheej tiv thaiv muab los ntawm cov txheej txheem zintec muab kev tiv thaiv thaum thauj, khaws cia, thiab tsim khoom thiab. Txawm li cas los xij, nws raug nquahu kom siv cov khoom siv nrog cov xim pleev xim yog tias nws siv nyob rau hauv ib puag ncig corrosive heev.
Dab tsi yog Galvanised?
Galvanizing yog txheej txheem peb siv los ua cov txheej zinc nyias ntawm cov khoom siv hlau los ntawm submerging cov khoom ntawm cov zinc da dej. Ntawm no, zinc tuaj yeem ua raws li kev txi anode los tiv thaiv cov hlau los ntawm xeb. Qhov ntawd txhais tau tias, yog tias muaj khawb ntawm cov zinc txheej, cov hlau tseem tiv thaiv.
Peb hu txoj kev no kub-dip galvanization vim nws siv cov zinc da dej ntawm qhov kub thiab txias, thiab cov khoom yog dipped rau hauv nws kom tau ib txheej hlau siv rau saum npoo ntawm cov hlau.
Qhov txawv ntawm Zintec thiab Galvanised yog dab tsi?
Zintec thiab galvanized xa mus rau daim ntawv thov ntawm cov zinc txheej nyias ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm zintec thiab galvanized yog tias cov khoom siv zintec yog tsim los ntawm electrolysis, thaum cov khoom galvanized yog tsim los ntawm submerging nyob rau hauv ib tug molten zinc da dej. Thaum xav txog cov khoom siv hlau me me (vim tias feem ntau cov hlau me me yog siv hauv ntau qhov kev lag luam), cov txheej txheem zintec yog qhov tsim nyog dua piv rau galvanizing vim tias cov hlau me me feem ntau yog muab los ua cov ntawv nyias thiab nws tsis tuaj yeem tau txais cov zinc txheej ntawm cov ntawv nyias.
Ntxiv mus, zinc txheej ntawm zintec txoj kev xav tau ntau txheej nrog cov xim yog tias cov khoom siv nyob rau hauv ib puag ncig corrosive heev. Txawm li cas los xij, galvanizing tsis xav tau txheej txheej ntxiv vim tias cov txheej txheem muab cov hlau nrog cov zinc txheej tuab heev. Yog li, qhov no kuj yog qhov sib txawv ntawm zintec thiab galvanised.
Summary – Zintec vs Galvanised
Zintec thiab galvanized xa mus rau daim ntawv thov ntawm cov zinc txheej nyias ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm zintec thiab galvanized yog tias cov khoom zintec yog tsim los ntawm electrolysis, whereas cov khoom galvanized yog tsim los ntawm submerging nyob rau hauv ib tug molten zinc da dej.
