1.Dab tsi zoo tib yam txias- dov carbon steel coils (xws li SPCC) ncaj qha siv los ua cov phaj electrode rau hydrogen roj hlwb?
Tej yam txias txias-rolled carbon steel (tsawg-carbon steel) yog tsis tsim nyog vim hais tias nws corrodes sai heev nyob rau hauv hnyav, acidic, humid, thiab hluav taws xob nqi ib puag ncig ntawm cov roj hlwb, ua rau kev ua tau zoo degradation thiab paug, thiab yog li ntawd tsis kam lees tawm tam sim ntawd.
Txias-rolled stainless steel coils yog cov neeg sib tw zoo tshaj plaws hauv qab: Los ntawm kev ua kom txias txias kom ua tiav qhov yuav tsum tau nyias nyias thiab qhov tseeb, ua raws li kev hloov kho saum npoo av, nws tuaj yeem ua tau raws li yuav luag txhua qhov yuav tsum tau ua ntawm cov hlau bipolar daim hlau, sawv cev rau cov kev taw qhia tseem ceeb rau kev lag luam tam sim no.
2.Dab tsi yog qhov yuav tsum tau ua rau cov phaj bipolar hauv hydrogen roj hlwb?
Kev tiv thaiv corrosion siab: Kev ua haujlwm ib puag ncig: ~ 80 ° C, av noo, acidic (pH 2-3), muaj peev xwm electrode. Cov ntaub ntawv yuav tsum muaj kev ruaj ntseg ntev nrog cov nqi qis heev.
High conductivity: Qhov chaw tiv thaiv yuav tsum tsis tshua muaj siab kom txo qis hauv cell tsis kam thiab txhim kho efficiency.
Hermeticity zoo heev: tiv thaiv tau hydrogen thiab oxygen cross- paug.
Zoo mechanical zog thiab formability: Electrode thickness feem ntau tsuas yog 0.05-0.2 hli, yuav tsum tau kev txhawb nqa rau tag nrho cov roj cell pawg siab thiab muaj peev xwm ua tau meej imprint complex flow channels rau nws.

3.Vim li cas txias txias - dov carbon steel phased tawm?
Corrosion tsis kam: Ua tsis tau tiav. Ceev ceev generalized corrosion thiab pitting yuav tshwm sim nyob rau hauv lub roj cell ib puag ncig, ua rau:
Hlau ion leaching, lom cov catalyst.
Kev tiv thaiv ntau ntxiv vim cov khoom siv corrosion.
Inferior airtightness vim corrosion substrate.
Surface conductivity: Tsis zoo. Lub ntuj tsim oxide txheej ntawm cov pa roj carbon steel nto tsis yog -conductive, ua rau muaj kev tiv thaiv siab.
Nyhav: hnyav. High density, uas yog detrimental rau nce zog ceev.
4.Vim li cas txias- dov stainless hlau coils dhau los ua lub ntsiab hlau substrate?
Inherent Advantages:
Kev tiv thaiv corrosion zoo heev: Ntau qhov kev txiav txim siab ntau dua li carbon steel.
Lub zog siab thiab toughness: Haum rau ultra-thinning (txias- dov rau 0.05mm) thiab precision stamping.
Inherently zoo heev airtightness.
Daim ntawv zoo meej thiab qhov tseeb qhov tseeb tuaj yeem ua tiav los ntawm kev sib tw txias.
Tau Txais Cov Khaub Ncaws thiab Cov Kev daws teeb meem: Cov "passivation film" (chromium oxide) ntawm stainless hlau tseem tsis ruaj khov txaus nyob rau hauv ib puag ncig ntawm cov roj cell, thiab nws qhov kev tiv thaiv kuj tseem siab. Yog li ntawd, ib tug functionalized txheej yuav tsum tau siv rau nws nto, uas yog lub core technology.
Lub Hom Phiaj Txheej: Txhawm rau muab ob qho tib si "cov khoom siv tiv thaiv" thiab "corrosion tiv thaiv thaiv" ua haujlwm.
Mainstream Txheej Technologies:
Lub cev Vapor Deposition (PVD): Xws li kub plating, platinum plating (kev ua tau zoo heev tab sis kim), los yog cov pa roj carbon ntau dua -raws li cov txheej txheem (xws li pob zeb diamond-xws li carbon (DLC), graphite carbon).
Chemical Vapor Deposition (CVD).
5.Dab tsi yog lub luag haujlwm thiab cov txheej txheem ntawm cov hlua txias -rolled coil nyob rau hauv qhov kev lag luam saw no?
Cov txheej txheem ntau lawm rau lub caij txias - dov stainless hlau bipolar ntawv yog raws li nram no: Stainless hlau smelting → Kub dov → Pickling → Txias dov (rau lub hom phiaj thinnest specification, xws li 0.1 hli) → Annealing → Finishing → Precision slitting → Precision stamping (kev sib tw khiav, CV thiab lwm yam) . → Kev tshuaj xyuas thiab ntim khoom
Lub luag haujlwm tseem ceeb ntawm lub caij txias dov: muab cov substrate strip coils nrog cov tuab tuab, cov duab ncaj, du nto, thiab cov khoom siv kho kom zoo ib yam. Nws qhov zoo ncaj qha txiav txim siab cov txiaj ntsig ntawm cov ntawv tom ntej thiab cov txheej txheem sib xws.
