Thaum xaiv thiab siv SECC Sheet (galvanized steel ntawv), cov yam ntxwv hauv qab no feem ntau yog kev txaus siab, raws li lawv cuam tshuam ncaj qha, thiab siv cov ntawv thov:
1. Corrosion Kuj
TSEEM CEEB TSOM: Lub xeb - tsis txaus siab thiab kho cov qauv chromate.
Cuam tshuam cov ntsiab lus:
Galvanized Txheej Thickness (Kev Tsim Qauv Tshiab (Z18, uas tus xov tooj sawv cev rau zinc txheej hnyav hauv G / M²).
Chromate txheej hom (chrome - dawb, troment chromium, hexavalent chromium muaj ntau dua corrosion tsis kam tab sis yuav tsis ncav ib puag ncig cov qauv ib puag ncig.
Txoj Kev Kuaj: Kev kuaj tshuaj ntsev (piv txwv li, 72H / 120H nruab nrab ntsev tsuag ntsuas cov txiaj ntsig).
2. Cov saum npoo zoo
Cov tsos yuav tsum tau: Yog cov khoom zoo nkauj thiab pub dawb ntawm cov tsis taus (xws li cov tsev nyob yuav tsum tau khawb hauv thiab pob)?
Txheej Txheem Kho:
Li niaj hnub chromate (zaj sawv xim xim) vs. Chrome - passivation dawb (nyiaj- dawb).
Qee cov ntawv thov xav tau cov duab txuas ntxiv lossis luam ntawv, xav tau muaj cov nplaum nplaum nto nto muaj zog.
3. Machinability
Punching / Dabtsi Yog Khoov:
Puas yog txheej muaj txiaj ntsig rau tev? (Qhov sib koom ua lub zog ntawm zinc txheej rau lub substrate yuav tsum tau ntsuas.)
Ductility (piv txwv li, elongation ntawm SECC feem ntau 30% -40%).
Vuam Performance:
Zinc vapor yuav cuam tshuam vuam zoo (kev hloov kho tam sim no lossis kev siv cov ntaub ntawv vuam tshwj xeeb yuav yog qhov tsim nyog).
Kev tiv thaiv xeb: Ua cov npoo uas yuav tsum tau kev kho mob ntxiv tom qab txiav (piv txwv li, anti- xeb pleev xim)?
4. Ua haujlwm thiab hluav taws xob tiv thaiv
Kev Lag Luam Hluav Taws Xob Xyuas:
Puas muaj cov chromate txheej cuam tshuam kev cuam tshuam? (Cov yeeb yaj kiab tuab yog feem ntau tsuas yog 0.1-1μm, yog li qhov cuam tshuam yog tsawg dua.)
Puas yog hluav taws xob tiv thaiv yuav tsum tau? (Secc nws tus kheej yog tus saib xyuas, tab sis tsis zoo li zoo li cov tooj liab lossis txhuas.)
5. Ib puag ncig ua raws
RoHS / Tauj Ua Raws:
Nws puas muaj hexavalent chromium (CRROMALENT (CRRO, uas yog tshuaj lom thiab yuav tsum muaj chromium {} {dawb los yog cov chromium dawb lossis hloov cov txheej txheem hloov).
Rov qab siv dua tshiab (Galvanized steel tuaj yeem rov ua tau dua tshiab, tab sis zinc txheej yuav tsum tau sib cais).
6. Tus nqi thiab kev ua haujlwm {- rau - kev ua tau zoo
Piv cov khoom siv:
Piv rau SGCC (kub {- dip galvanizing): Secc muaj cov txheej txheej ntau dua tab sis tus nqi siab dua.
Piv rau stainless hlau (sus304): tsawg corrosion tsis kam tab sis tus nqi qis thiab ua tau yooj yim.
Thickness xaiv: 0.5-3.0 hli feem ntau siv. Thickness nce tus nqi, thaum nyias ua rau muaj zog.
7. Qhov sib txawv ntawm cov ntawv teev npe raug cai

Q1: Kuv yuav ua li cas yog tias cov npoo ntawm SECC Daim Ntawv Rust tom qab Stamping?
A1: Peb pom zoo xaiv cov khoom siv nrog cov txheej txheej tuab (xws li Z18) lossis thov tus neeg sawv cev passivating tom qab txiav.
Q2: Tau SCC Hloov Cov Hlau Stainless rau Kev Siv Sab Nraud?
A2: Luv luv - xyoo, yog; Ntev - sij hawm, Tsuag txheej yog qhov yuav tsum tau rau kev tiv thaiv (Secc tsis yog huab cua {}} tiv taus raws li stainless hlau).
