1. Dab tsi yog galvanized steel ntawv?
Galvanized steel ntawv yog hlau daim ntawv coated nrog ib txheej ntawm cov pa zinc nyob rau saum npoo ntawm cov roj carbon lossis qis} almoy qauv hlau substrate los ntawm ib tug txheej txheem tshwj xeeb. Nws cov haujlwm tseem ceeb yog siv qhov kev tiv thaiv anodic kev tiv thaiv ntawm zinc kom noo, txhim kho nws lub neej pabcuam.
Dab tsi yog qhov kev faib tawm tseem ceeb ntawm cov ntawv galvanized?
Cov hau kev ntawm cov txheej txheem ib txwm muaj xws li cov txheej txheem galvanizing, zinc txheej thickness / hnyav, cov khoom siv substrate. Lawv muaj raws li nram no:
Cov txheej txheem Galvanizing: kub - dip galvanized ntawv (piv txwv li ultrasonic 1}} dip galvanized ntawv, thiab lwm yam.
Zinc Txheej hnyav: lub teeb zinc txheej (piv txwv li, hauv qab 40G / m²), nruab nrab ntawm daim npog zinc
Substrate Cov Khoom Siv: Cov Muam Hlau Galvanized Ntawv (Feem Ntau Siv Tau), Qe, Q35 {{5} {}} Cov hlau galvanized ntawv
Chaw Mob Zinc: Cov Ntawv Zinc Me Nyuam, Tsis Muaj Tus Zinc Num, Zinc {} {} {{{- coated sheet)
Dab tsi yog cov tub ntxhais sib txawv ntawm kub - dip galvanized ntawv (gi) thiab electrogalvanized ntawv (piv txwv)? Qhov ob txawv txawv nyob rau hauv cov txheej txheem, kev ua tau zoo, thiab tus nqi. Cov tub ntxhais sib txawv muaj raws li nram no:
Cov txheej txheem sib txawv: GI raus dej rau hauv Molten Zinc (kwv yees li 450 degree), sib sau ib txheej zinc los ntawm kev siv tshuaj lom neeg thiab cov nplaum ntawm lub cev; Piv txwv li tso cov txheej zinc ntawm lub substrate nto los ntawm electrolysis (chav tsev / qis {{1} -
Txawv Zinc Txheej Ntau Dua: Gi Zinc Zinc yog Thicker (Feem Ntau 50-200 G / M²), muaj cov kab tsuag muaj zog, thiab tuaj yeem ua rau muaj kab tshaj cum; Piv txwv li Zinks yog thinner (feem ntau 10-50 g / m²), yog cov khaub ncaws zoo heev, thiab muaj cov chaw ua si smoother.
Sib txawv corrosion: GI muaj zog corrosion tsis kam (tshwj xeeb yog nyob rau hauv ib puag ncig sab nraum zoov), thaum piv txwv li tsis muaj zog corrosion tsis kam thiab yog qhov tsim nyog rau cov chaw ib puag ncig.
Cov nqi sib txawv thiab cov ntawv thov: GI tsis tshua kim thiab siv hauv kev tsim kho thiab kev sib tham sab nraum zoov; Piv txwv li yog kim dua thiab siv rau cov cuab yeej siv hauv tsev thiab cov khoom ntsuas.
4. Dab tsi tshwj xeeb txog kev sib cais kub - dip galvanized steel (GA)?
GA undergoes ib qho kev kho mob ntxiv " Nws cov yam ntxwv tseem ceeb suav nrog:
Lub zinc txheej yog ib txheej alloy (tsis muaj cov txheej dawb paug), dawb ntawm weldability, thiab muaj kev tsaus ntuj nti txho (tsis muaj "Zinc Plem tawg";
Cov txheej muaj muaj zog adhesion (tsim nyog rau cov duab txuas ntxiv thiab cov lamination), thiab kev khawb tsis zoo dua li GI;
Lub corrosion tsis kam yog qis dua GI nrog tib Zinc Txheej ceeb thawj, tab sis ntau dua li xws li. Nws yog feem ntau siv nyob rau hauv Automotive lub cev thiab siab -}}}} end end} home appl home .້ນ.
5. Dab tsi yog spangle? Puas yog SPANGLE LOJ Pheej cuam tshuam kev ua yeeb yam ntawm cov ntawv galvanized?
Spangle yog cov qauv hexagonal tsim thaum cov zinc kev hloov kho thiab crystallizes ntawm lub substrate nto thaum kub {}} dip galvanizing. Nws yog qhov tseem ceeb txoj kev loj hlob txawv ntawm zinc muaju. Spangle loj yog tswj los ntawm tus nqi txias thiab zinc yaj muaj pes tsawg leeg (xws li cov tshuaj pleev ib ce thiab cov hmoov txhuas nyob rau hauv cov kab txawv loj, ua kom sov sai sai.
Kev cuam tshuam ua tau: spangle loj tsis cuam tshuam rau corrosion tsis kam lossis cov khoom siv tshuab ua, tsuas yog nws qhov tsos. Cov duab loj loj yog feem ntau siv nyob rau hauv cov vaj huam sib luag hauv tsev (rau tus nqi qis dua), thaum tsis muaj spangles siv tau hauv cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob (rau cov khoom siv zoo thiab yooj yim).
