99% Vanadium Pentoxide Flake

99% vanadium pentoxide flake yog cov hlau oxide nrog cov mis molecular V2O5.Cov tsos mob thiab cov khoom siv: Txiv kab ntxwv-daj, cib-liab, liab-xim av crystalline hmoov los yog grey-dub flakes. Me ntsis soluble nyob rau hauv dej, insoluble nyob rau hauv ethanol, soluble nyob rau hauv muaj zog acid, muaj zog alkali.

1. Mining thiab Concentration

Kev rho tawm: Vanadium feem ntau yog muab rho tawm los ntawm vanadium-bearing ores xws li vanadinite, patronite, carnotite, thiab magnetite. Cov ore no yog mined los ntawm lub ntiaj teb siv cov txheej txheem mining pa.

Crushing thiab sib tsoo: Cov ore rho tawm yog crushed thiab hauv av rau hauv cov khoom zoo kom ua rau thaj chaw saum npoo rau cov tshuaj tiv thaiv tom ntej. Cov txheej txheem kev siv tshuab no yuav pab kom dim ntawm vanadium los ntawm ore matrix.

Kev pab: Lub hauv av ore yog raug rau cov txheej txheem beneficiation, xws li lub ntiajteb txawj nqus sib cais, sib nqus sib nqus, thiab flotation, kom mloog zoo rau cov ntsiab lus vanadium. Lub hom phiaj yog tsim kom muaj kev mloog zoo nrog feem pua ​​​​ntawm vanadium thiab qis impurities.

2. Ci

Ntsev Roasting: Cov concentrated vanadium ore yog tov nrog sodium ntsev, feem ntau yog sodium carbonate (Na₂CO₃) lossis sodium chloride (NaCl), thiab tom qab ntawd muab ci rau hauv qhov cub kub kub (kwv yees li 850-950 degree lossis 1562-1742 degree F) . Cov txheej txheem no hloov vanadium oxides hauv cov ore mus rau soluble sodium vanadate (NaVO₃).

Oxidation: Thaum lub sij hawm ci, vanadium nyob rau hauv cov ore yog oxidized rau lub +5 oxidation xeev, tsim vanadium pentoxide raws li ib tug intermediate compound. Cov txheej txheem roasting kuj pab tshem tawm impurities thiab txhim kho cov purity ntawm cov khoom vanadium.

3. Leaching

Kev ywg dej nrog dej: Cov khoom ci ci yog leached nrog dej kom yaj cov sodium vanadate, tsim cov tshuaj vanadium-nplua nuj. Cov insoluble residue, uas muaj impurities, yog sib cais los ntawm filtration.

Kev huv huv: Cov tshuaj vanadium-nplua nuj dhau mus ntxiv cov kauj ruam purification kom tshem tawm cov impurities seem. Qhov no tuaj yeem koom nrog kev lim dej ntxiv, nag lossis daus, thiab ion pauv txheej txheem.

4. Dej nag

Ammonium Metavanadate Precipitation: Ammonium chloride (NH₄Cl) yog ntxiv rau purified vanadium tov rau precipitate ammonium metavanadate (NH₄VO₃). Cov tshuaj tiv thaiv no tshwm sim vim hais tias ammonium metavanadate yog insoluble hauv dej, tso cai rau nws cais tawm ntawm cov tshuaj.

Lim thiab ntxuav: Lub precipitated ammonium metavanadate yog lim tawm los ntawm kev daws thiab ntxuav kom huv si kom tshem tawm cov dej tsis huv.

5. Calcination

Calcination: Tom qab ntxuav ammonium metavanadate yog calcined nyob rau hauv lub cub tawg ntawm qhov kub ntawm 450 degree mus rau 700 degree (842 degree F txog 1292 degree F). Thaum lub sij hawm calcination, ammonium metavanadate decomposes tsim vanadium pentoxide (V₂O₅) thiab tso tawm ammonia roj (NH₃).

2NH4VO3 →V2O5+2NH3+H2O2 NH₄VO₃ \rightarrow V₂O₅ + 2 NH₃ + H₂O2NH4​VO3 →V2O5​+2NH3 +H2O

Flake Formation: Cov khoom calcined yog txias thiab tsim rau hauv flakes. Cov xwm txheej tshwj xeeb ntawm calcination, xws li kub thiab sijhawm, tuaj yeem hloov kho kom tswj tau qhov loj thiab zoo ntawm vanadium pentoxide flakes.

A: ISO9001 thiab Test Report, kuj peb tuaj yeem siv lwm cov ntawv pov thawj tsim nyog.

Q: Koj lub tuam txhab puas muaj peev xwm ua tau raws li qhov xav tau ntawm cov neeg siv khoom?

A: Peb lub tuam txhab muaj lub zog muaj zog, ruaj khov thiab muaj peev xwm mus sij hawm ntev kom tau raws li ntau yam kev xav tau ntawm cov neeg siv khoom.

Q: Koj puas tuaj yeem ua cov khoom raws li cov neeg siv khoom xav tau?

A: Peb tuaj yeem ua tau raws li txhua yam khoom lag luam customized raws li cov neeg siv khoom.

Q: Koj puas yog cov chaw tsim khoom lossis kev lag luamr?

A: Chaw tsim tshuaj paus thiab tsum. ZhenAn yog ib lub tuam txhab tshwj xeeb hauv cov khoom siv hlau, kev tsim khoom, kev ua, kev muag khoom, thiab kev lag luam thiab xa tawm nrog 30+ xyoo dhau los. Qee lub sij hawm peb pab peb cov neeg muas zaub cov khoom lag luam raws li cov tub luam.
