Cov khoom siv thiab Flake Form
Vanadium pentoxide, sau V2O5, yog xim av rau txiv kab ntxwv crystalline oxide nrog lub melting point ze 690 degrees Celsius, thiab nws yog tsim los ntawm vanadium bearing slag, titanomagnetite ore concentrates los yog siv catalysts thiab residues. Daim ntawv flake yog tsim los ntawm kev ua kom txias ib qho molten los yog fused loj kom nws solidifies rau hauv nyias platelets, uas yog yooj yim los tuav, hnyav thiab yaj dua cov hmoov thiab tsim cov hmoov av tsawg. Flake yog daim ntawv nyiam tshaj plaws rau cov neeg siv khoom siv hlau thiab tshuaj lom neeg feem ntau vim tias nws ntws thiab tsub kom zoo, thaum hmoov thiab granulated cov ntaub ntawv muaj rau kev sib cais thiab cov txheej txheem catalyst. Cov qhab-nees tus qauv tau txhais nyob rau hauv specifications xws li GB/T 3283 thiab dav pauv nrog ib tug purity tshaj tawm ntawm 98, 98.5, 99, 99.5 los yog 99.6 feem pua.
Purity Bands thiab impurity txwv
Daim duab purity hais txog V2O5 cov ntsiab lus, thiab qhov sib txawv ntawm cov bands yog nyob rau hauv cov impurity ntsiab uas tseem tshuav. Hlau, silicon, txhuas, phosphorus, sulfur, arsenic thiab alkali hlau yog cov kev tswj tsis tu ncua, thiab txhua qhov cuam tshuam rau kev siv qis. Hlau thiab silicon tsis yog ib qho tseem ceeb rau ferrovanadium pub tab sis tseem ceeb rau catalyst thiab chemical siv, thaum arsenic thiab sulfur yuav tsum tau khaws cia tsawg heev rau catalyst ntau lawm thiab rau electrolyte lub luag hauj lwm. Cov neeg yuav khoom yuav tsum qhia meej txog qhov txwv tsis pub tshaj uas lawv cov txheej txheem yuav tsum tsis yog tsuas yog cov xov xwm purity xwb, vim tias 99 feem pua cov khoom siv los ntawm ib tus neeg tsim khoom tuaj yeem muaj qhov txawv txav tsis zoo los ntawm 99 feem pua cov khoom siv los ntawm lwm tus. Daim ntawv pov thawj ntawm kev tsom xam rau qhov tseeb ntau, tsis yog cov lus qhia dav dav, yog cov ntaub ntawv tseem ceeb.
Siv raws li Ferrovanadium Feedstock
Kev siv ntau tshaj plaws ntawm vanadium pentoxide yog kev tsim cov ferrovanadium los ntawm kev txo qis aluminothermic, qhov twg cov oxide txo nrog txhuas kom muab cov pa roj carbon tsawg uas muaj li ntawm 50 mus rau 80 feem pua vanadium. Cov oxide kuj tseem siv ncaj qha rau hauv qee txoj kev steelmaking thiab alloying. Rau daim ntawv thov no cov ntsiab lus tseem ceeb yog cov ntsiab lus vanadium, theem ntawm impurities uas yuav qhia rau cov hlau los yog cov slag, thiab lub cev daim ntawv thiab noo noo, vim noo noo cuam tshuam rau qhov hnyav, txo qhov sib npaug thiab kub tsim. Qhov loj me me thiab cov ntsiab lus tsis zoo yuav pab txo qis kom rov ua dua tshiab, thiab cov oxide yuav tsum tau khaws cia qhuav vim nws yog hygroscopic thiab yuav khaws cov dej noo yog tias sab laug raug.
Siv hauv Catalysts thiab Flow Batteries
Vanadium pentoxide yog lub hauv paus rau catalysts siv nyob rau hauv sulfuric acid ntau lawm thiab nyob rau hauv ib tug ntau yam ntawm xaiv oxidation txheej txheem, qhov twg cov oxide yog ua ke nrog cov txhawb nqa ntawm ib tug txhawb nqa thiab cov catalyst kev ua tau zoo yog rhiab heev rau kab impurities. Nws tseem yog lub hauv paus ntawm vanadium electrolyte rau vanadium redox flow batteries, uas khaws lub zog hauv cov kua electrolytes ntawm vanadium hauv sulfuric acid. Cov khoom siv roj teeb xav tau qis heev ntawm cov impurities uas tuaj yeem hla cov kab mob electrolyte los yog degrade daim nyias nyias, thiab kev lag luam thiaj li nyiam mus yuav ntau dua purity flake thiab tswj kev sib cais thiab electrolyte npaj kom nruj. Nyob rau hauv ob qho tib si daim ntawv thov keeb kwm ntawm tus neeg muag khoom, ntau traceability thiab qhov sib xws ntawm kev xa khoom tiav yog qhov tseem ceeb raws li kev tshaj tawm purity.
Ntim, tuav thiab muab kev ruaj ntseg
Vanadium pentoxide feem ntau tau ntim rau hauv cov nruas steel lossis hauv ib lub hnab loj loj nrog cov kab dej ntub dej, thiab cov ntim yuav tsum khaws cov khoom kom qhuav thiab tiv thaiv kev sib cuag nrog cov neeg ua haujlwm txo qis thiab cov khoom siv organic. Nws raug cais raws li cov khoom siv phom sij hauv ntau lub tebchaws, thiab daim ntawv pov thawj kev nyab xeeb, cov chav kawm ntawm kev ntim khoom thiab cov ntaub ntawv thauj khoom yuav tsum muab nrog rau txhua qhov khoom xa tuaj. Cov neeg yuav khoom yuav tsum paub meej tias lub peev xwm ntau lawm thiab qhov chaw pub khoom noj ntawm tus neeg muag khoom, vim tias cov khoom siv vanadium pentoxide yog ze rau cov khoom siv hlau ua slag thiab rov qab siv cov catalysts, ob qho tib si muaj lawv lub voj voog. Ib txoj kev npaj yuav tsum suav nrog lwm yam hauv paus chiv keeb, kev pom zoo ntawm tus nqi, thiab cov txheej txheem kev ntsuam xyuas kev tsis sib haum xeeb rau cov xwm txheej uas tau txais ntau poob sab nraum pawg neeg pom zoo.
