1. Nhanganyaya
Vanadium pentoxide ndiyo oxide inonyanya kushandiswa muvanadium, inoonekwa seupfu hwe crystalline hweorenji-yero kana kuti solid yakapfava. Inoratidza hunhu hwe amphoteric oxide, inonyungudika zvishoma mumvura, uye inonyungudika nyore nyore mu acids ne alkalis. Maumbirwo ayo e crystal ane layered uye variable valence state zvinoita kuti isatsiviwe mu catalysis, electrochemical energy storage, uye optical materials. Nekuvandudzwa kwesimba idzva repasi rose, makemikari akanaka, uye maindasitiri ekugadzira emhando yepamusoro, kudiwa kwevanadium pentoxide yakachena uye isina kuchena kuri kuramba kuchikura. Semugadziri mukuru wevanadium pasi rose, China, ichishandisa zvakanakira zvayo zvekushandisa uye kufambira mberi kwetekinoroji, yave chinhu chikuru muchina wepasi rose wekupa vanadium pentoxide.

2. Hunhu hwechigadzirwa uye zvirevo
Zviratidzo zvikuru zvehunyanzvi zvevanadium pentoxide zvinosanganisira kuchena, kusvibiswa, kupararira kwehukuru hwezvidimbu, uye chimiro chemuviri. Zvinodiwa nevatengi zvinosiyana zvichienderana nekushandiswa.
- Magiredhi eKuchena: Giredhi remaindasitiri (98% ~ 99.5%), giredhi reKuchena Kwakanyanya (99.9% ~ 99.99%). Zvigadzirwa zveKuchena Kwakanyanya zvinonyanya kushandiswa mumagetsi, optical, uye specialty catalysts.
- Kudzora kusvibiswa: Miganhu inowanzo sanganisira zvinhu zvakaita sesodium, potassium, iron, silicon, nesarufa zviri pasi pechipimo chakati kuti zvive nechokwadi chekuti zvigadzirwa zviri pasi pemvura zvinoshanda zvakanaka.
- Chimiro chemuviri: upfu (zviri nyore kuparadzira nekusanganisa) kana zvidimbu (zviri nyore kutakura nekudyisa), saizi yezvidimbu inogona kugadziriswa (semuenzaniso, D50 = 10~50 μm).
- Muenzaniso wezvinotsanangurwa zvakajairika:
- Zviri mukati meV₂O₅ ≥ 99.5%
- Kusachena Fe ≤ 0.05%, S ≤ 0.03%, Na ≤ 0.02%
- Saizi yepepa: 5~15 mm kana zvichienderana nezvinodiwa nevatengi
3. Nzvimbo huru dzekushandisa
3.1 Indasitiri yeCatalyst
Vanadium pentoxide ndiyo inonyanya kukosha mukugadzira sulfuric acid, inoshandiswa kuoxidize sulfur dioxide kuita sulfur trioxide. Uyezve, inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakasikwa:
- Kuoxidation kweethanol kuita acetaldehyde
- Kuoxidation ye o-xylene kuti igadzire phthalic anhydride
- Kugadzirwa kwezvinhu zvepakati zvakaita sepolyamide neoxalic acid
- Zvikamu zvinoshanda mu flue gas denitrification (SCR denitrification catalyst)
3.2 Girazi nezvinhu zvinovheneka
Vanadium pentoxideinogona kushandiswa sechinhu chinoisa ruvara kana kuti chinonyungudutsa ultraviolet pagirazi, mukugadzira magirazi ekuona, mafirita, nezvinhu zve photochromic. Nzvimbo yayo yekunyunguduka kwepamusoro uye kugadzikana kwayo pakupisa zvinoitawo kuti ikodzere kushandiswa muma ceramic glazes uye electronic ceramics.
3.3 Zvinhu zveSimba
- Mabhatiri eVanadium: Vanadium pentoxide chinhu chakakosha chemabhatiri e all-vanadium redox flow, anoshandiswa kugadzira ma electrolytes uye kuwana kuchengetwa kwesimba kwakakura.
