Vim li cas PEM lim xav tau siab Purity Tsawg Oxygen Sintered Hlau Hmoov?
Thaum ib qho hluav taws xob tam sim no ntws los ntawm dej, nws faib ua hydrogen thiab oxygen. Cov txheej txheem no hu ua PEM dej electrolysis. Cov sintered ntxeem tau hlau lim nyob rau hauv cov khoom no tas li raug rau kub kub, acidic tej yam kev mob, thiab oxidative kev nyuaj siab. Cov txheej txheem hlau hmoov uas muaj ntau impurities los yog huab cua ntau dhau ua rau cov qauv sintering tsis muaj zog, uas ua rau kom xeb thiab ua rau muaj teeb meem nrog hluav taws xob tsis kam.
Cov ntsiab lus lim uas kav ntev yog tsim los ntawm siab -purity titanium hmoov nrog rau cov pa oxygen tswj. Cov txheej txheej passivation uas tiv thaiv titanium los ntawm corrosive nres yog tawg los ntawm impurities xws li hlau, carbon, thiab nitrogen. Thaum cov pa oxygen nce siab tshaj qhov zoo tshaj plaws thaum lub sij hawm cov hmoov ntau lawm, lub sintering moj khaum muaj qis hluav taws xob conductivity. Qhov no cuam tshuam ncaj qha rau cov txheej txheem electrolytic ua haujlwm zoo li cas ntawm daim nyias nyias nyob ze.
Lub sijhawm ua haujlwm thiab kho tsis tu ncua yog raws li qhov ruaj khov ntawm cov ntaub ntawv lim dej electrochemically. Tsawg-oxygen sintered hlau hmoov ua rau lub qhov hws uas tag nrho cov loj thiab zoo tib yam, thiab cov hais ib txwm sib koom ua ke mechanically. Qhov kev sib sau ua ke no ua kom cov dej thiab roj tuaj yeem txav mus los ntawm cov qauv hauv txoj kev xav tau, txawm tias thaum hloov pauv. Cov neeg siv khoom siv hais tias thaum lawv siv cov ntxaij lim dej ua los ntawm cov hmoov hmoov zoo substrates, lawv tsis tas yuav hloov qhov feem ntau.
Tag nrho cov nqi ntawm cov tswv cuab rau cov chaw tsim khoom loj hydrogen kuj cuam tshuam los ntawm cov ntaub ntawv siv. Thaum txom nyemsintered hlau hmoovcov ntaub ntawv yog siv los ua cov lim dej, lawv yuav tsum tau hloov ntau zaus, uas txwv tsis pub ntau lawm thiab nce nqi. Muab nyiaj tso rau hauv siab - qib hmoov thev naus laus zis them nyiaj ntau dhau los ntawm kev ua kom cov khoom siv ntev dua thiab txo qhov tsis ua haujlwm.
High Purity Tsawg Oxygen Sintered Hlau Powder rau Titanium Lim Elements
Material Composition Standards for PEM Applications
Titanium hmoov ua rau lim dej hydrogen yuav tsum muaj tsawg dua 0.15% oxygen los ntawm qhov hnyav txhawm rau ua haujlwm ntawm nws qhov zoo tshaj plaws. Thaum ua hmoov, cov tuam txhab uas siv lub tshuab nqus tsev atomization lossis hydrogenation- txoj kev dehydrogenation tuaj yeem tswj tau cov pa oxygen ntau npaum li cas. Daim ntawv ntawm cov khoom cuam tshuam li cas lawv sinter, nrog cov hmoov kheej kheej ntim ntau dua li cov duab khib.
Sintering txheej txheem Optimization rau Enhanced Conductivity
Cov ntawv cog lus metallurgical uas tsim ntawm cov hmoov hmoov yog cuam tshuam ncaj qha los ntawm qhov kub thiab txias profiles uas siv thaum sintering.
