Lub cev thiab tshuaj lom neeg ntawm vanadium pentoxide
Ntws: 3.357 g / cm3
Melting taw tes: 690 degree
BLAIL NTAM: 1750 degree
Molecular hnyav: 182
Zog: Txiv kab ntxwv-daj
Solubility: soluble hauv concenrated acid thiab alkali, me ntsis soluble hauv dej, insoluble hauv kev ua ethanol.
Nws evaporates tseem ceeb ntawm qhov kub tshaj 7 {0 0 degree. Nws decomposes rau oxygen thiab vanadium tetroxide ntawm 700 ~ 1125 degree, ua rau muaj ntau yam kev tawm tsam rau cov organic thiab inorganic cov tshuaj tiv thaiv. Nws yog tus neeg sawv cev oxidizing muaj zog thiab tuaj yeem txo qis rau ntau yam pheej yig oxides. Nws yog me ntsis soluble hauv dej thiab yooj yim cov ntaub ntawv muaj kev daws teeb meem ruaj khov. Nws yog soluble heev hauv alkali thiab tsim vanadate (vo 3-}) nyob rau hauv cov mob tsis muaj zog. Thaum yaj nyob rau hauv ib tug muaj zog acid (feem ntau soluble nyob rau hauv p}}}}} ions, tab sis ua cov vanadium ions (vo 2+). Rau cov tshuaj lom neeg lom, cov tshuaj lom, cov nyiaj tso cai tshaj plaws hauv huab cua yog tsawg dua 0.5 mg / m3.
Kev saib xyuas thaum muaj xwm ceev rau vanadium pentoxide teakage
Kev khomob kub ntxhov: cais cov khoom tsis huv ntawm qhov xau thiab txwv nkag tau rau nws. Nws raug nquahu tias cov neeg ua haujlwm thaum muaj xwm txheej ceev hnav tus kheej lub zog ua pa tau zoo thiab hnav cov khaub ncaws tiv thaiv lom. Zam kev plua plav, cheb nws kom huv si, muab tso rau hauv ib lub hnab thiab nqa mus rau qhov chaw nyab xeeb. Yog tias muaj ib qho xau loj loj, npog nws nrog qhwv yas lossis canvas. Sau thiab rov ua dua tshiab nws lossis coj nws mus rau qhov av pov tseg rau pov tseg.
Kev ua haujlwm thiab pov tseg ntawm vanadium pentoxide
Kev ceev faj rau kev ua haujlwm: kaw hom kev ua haujlwm, tso pa hauv zos. Cov neeg ua haujlwm yuav tsum yauv kawm tshwj xeeb thiab nruj me ntsis ua raws cov txheej txheem ua haujlwm. Cov neeg ua haujlwm tau qhia kom hnav lub ntsej muag plua plav (tag nrho ntsej muag), daim kab xev anti-lom cov khaub ncaws, thiab hnab looj tes roj hmab. Txav deb ntawm cov khoom siv hluav taws xob thiab cov ntaub ntawv sib txuas. Tsis txhob muaj hmoov av. Zam kev sib cuag nrog cov kua qaub. Ntsaws thiab tsis siv thaum thauj khoom kom tsis txhob ntim khoom thiab ntim. Siv cov cuab yeej siv rau kev tshem tawm thaum muaj xwm txheej ceev. Cov khoom ntim khoom yuav muaj cov tshuaj muaj teeb meem.
