Khoom thiab Kev Siv Ntawm Vanadium Pentoxide Flake

Vanadium pentoxide flakesyog grey-dub flakes, me ntsis soluble nyob rau hauv dej, insoluble nyob rau hauv ethanol, thiab soluble nyob rau hauv muaj zog acids thiab alkalis.

Amphoteric oxides, tab sis feem ntau yog acidic. Volatilizes ho siab tshaj 700 degree . Nws decomposes rau hauv oxygen thiab vanadium tetroxide ntawm 700-1125 degree . Cov yam ntxwv no ua rau nws muaj kev cuam tshuam rau ntau cov organic thiab inorganic tshuaj. Nws yog ib qho muaj zog oxidizing tus neeg sawv cev thiab tuaj yeem txo tau yooj yim rau ntau yam tsawg-valent oxides. Me ntsis soluble nyob rau hauv dej, yooj yim rau tsim ruaj khov colloidal tov. Nws yog yooj yim soluble nyob rau hauv alkali thiab muaj peev xwm tsim vanadate (VO-) nyob rau hauv weakly alkaline tej yam kev mob. Thaum yaj hauv cov kua qaub muaj zog (feem ntau pib yaj ntawm ib puag ncig pH=2), nws tsis tsim cov vanadate ions tab sis tsim cov pa oxygen vanadium ions (VO +) ntawm tib valence. Nws yog ib qho tshuaj lom thiab qhov siab tshaj plaws tso cai rau hauv huab cua yog tsawg dua 0.5mg / m³.

Vanadium yog cov hlau tsis muaj hlau. Vanadium pentoxide yog siv dav hauv metallurgy, tshuaj lom neeg kev lag luam, thiab lwm yam lag luam, feem ntau yog siv rau smelting hlau thiab vanadium. Nws yog siv los ua cov khoom siv ntxiv, suav txog ntau dua 80% ntawm tag nrho cov khoom siv ntawm vanadium pentoxide, thiab tom qab ntawd ua cov khoom siv rau cov tshuaj organic, suav txog li 10% ntawm tag nrho, thiab siv lwm qhov xws li vanadium pentoxide. Inorganic chemistry, tshuaj reagents, enamels, thiab cov khoom sib nqus suav txog li 10% ntawm tag nrho.

Kev ceev faj txog kev ua haujlwm: kaw kev ua haujlwm, tso tawm hauv zos. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu tias tus neeg teb xov tooj yuav tsum hnav lub npog ntsej muag (dawb lub ntsej muag), cov khaub ncaws ua pa, thiab hnab looj tes roj hmab. Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws kub. Zam kev tsim plua plav. Tsis txhob sib cuag nrog cov kua qaub. Thaum tuav, thauj khoom thiab tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj rau cov ntim thiab ntim. Nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Cov thawv ntim khoob yuav muaj teeb meem residues.

Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Lawv yuav tsum tau muab cais los ntawm cov khoom siv hluav taws xob (combustible) cov tshuaj, cov kua qaub, thiab cov tshuaj siv tau, thiab tsis txhob sib xyaw cia. Cov ntaub ntawv tsim nyog yuav tsum muaj nyob rau hauv qhov chaw cia kom muaj cov khoom nchuav.
