Dab tsi yog qhov kev sib raug zoo ntawm zinc txheej hnyav thiab zinc txheej tuab ntawm cov ntawv galvanized?

Dab tsi yog qhov kev sib raug zoo ntawm "zinc txheej hnyav" thiab "zinc txheej tuab" ntawm cov ntawv galvanized? Koj hloov lawv li cas?
Zinc Txheej Nyhav uas yog hais txog qhov loj ntawm zinc txheej rau ib qho chaw (piv txwv li}, feem ntau yog li 80}, feem ntau yog xa mus rau tag nrho cov hnyav ntawm ob sab).
Zinc Txheej Thickness hais txog lub cev tuab ntawm zinc txheej ntawm zinc txheej, ntsuas hauv μm (micrometers).
Hloov siab hloov tshiab: Thickness ({{0 μ= zinc txheej hnyav (G / M²) ÷ Zinc Qwj

7. Dab tsi yog cov ntawv galvanized cov qib? Lawv sawv cev dabtsi? Feem ntau siv cov qauv hlau hauv tsev ua raws GB / T 2518 (kub}} dip galvanized steel) thiab GB / T 15675 (hlau electrogalvanized). Noj GI ua piv txwv:
Q235 - Z: Q235 yog lub hauv paus cov khoom (qis}), thiab z qhia tau kub-dip galvanizing.
DC51d + Z: DC51D yog khaub thuas- kuas cov khoom siv), thiab + z qhia kub- dip galvanizing. Lub zinc txheej tuaj yeem muab ntxiv tom qab (piv txwv li, DC51d + Z80, lub ntsiab lus ib qho- Sided zinc txheej ntawm 80 g / m²).
HC340LA + ZF: HC340LA yog lub siab- Lub zog ntawm 340 MPA muaj zog ntawm 340 MPA
8. Dab tsi lwm hom ntawm Galvanized Steel yog Categories los ntawm daim ntawv thov? Downstream thov cov xwm txheej tuaj yeem raug faib ua hauv qab no:
Cov Panels siv: xws li ru tsev panels, phab ntsa phab ntsa, thiab cov keel yuav tsum muaj qhov zinc txheej hnyav (120g / m² lossis siab dua) thiab cua thauj khoom tawm tsam;
Cov khoom siv hluav taws xob hauv tsev: xws li tub yees sab panels thiab tshuab ntxhua khaub ncaws yuav tsum tau txo qis zinc Hliav, thiab pleev xim ntau;
Automotive panels: xws li lub cev panels (GA) thiab chassis Cheebtsam (GI) yuav tsum muaj lub zog siab thiab veldability zoo heev;
Cov tshuaj panels: xws li cov chaw tso tsheb hlau luam thiab cov kav dej yuav tsum muaj kua qaub thiab alkali tsis zoo (tej zaum yuav tsum tau txuas ntxiv) thiab qhov hnyav zinc txheej.
9. Dab tsi yog cov tub ntxhais kawm ua tau zoo ntawm galvanized ntawv? Muaj tsib qhov ntsuas tseem ceeb rau kev ntsuas cov ntawv galvanized zoo:
Corrosion Kuj: tsis kam rau atmospheric corrosion thiab ntsev corrosion;
Cov khoom siv neeg kho tshuab: tawm lub zog, thiab elongation ntawm substrate (cuam tshuam rau stamping formability);
Zinc txheej khoom: Adhesion (yooj yim ntawm zinc detachment) thiab kev sib dhos (tsis muaj kev sib txawv ntawm plating);
Cov khoom zoo: tsis muaj qhov tsis xws luag xws li khawb, pitting, ploj plating, thiab pob dub;
Kev ua cov khoom: Stamping, Bendability, thiab weldability (tshwj xeeb rau cov ntawv thov tsheb).
10. Yuav ua li cas yog corrosion tsis kam ntawm daim ntawv galvanized xeem? Cov hau kev uas nquag siv yog dab tsi? Peb txoj kev sim peb hom yog siv, sib xws rau cov xwm txheej sib txawv:
Kev nruab nrab ntsev tshuaj txau (NSS) Kev kuaj: Cov qauv yog muab tso rau hauv 5% thiab lub sijhawm ua kom muaj xeb dawb (substrate corrosion) kom pom tau sau tseg. GI feem ntau qhia tsis muaj xim dawb rau 48-120 teev.
Damp Kev Kuaj Cua sov: Cov qauv yog muab tso rau hauv ib puag ncig ntawm 40℃thiab 95% txheeb ze cov av noo, saib xyuas corrosion los simulation ib puag ncig.
Sab Nraud Sab Nraud: Cov qauv tau muab tso rau sab nraum zoov hauv ib puag ncig ntuj (xws li thaj chaw hiav txwv lossis taug chaw thaj chaw) los taug qab thaj chaw ntawm lub sijhawm ntev. Txoj kev no yog ze tshaj plaws nrog cov ntawv thov tiag tiag, tab sis cov voj voog ntsuas ntev dua (1-5 xyoos).
