Khoom Description
Vanadium pentoxide flake tsis yooj yim soluble hauv dej, tab sis vanadic acid yog tsim los ua kom cov kua qaub. Txawm hais tias nws yog insoluble nyob rau hauv sulfuric acid thiab nitric acid, nws yog soluble nyob rau hauv alkaline aqueous tov, thiab soluble nyob rau hauv hydrochloric acid, uas tso tawm chlorine gas thiab txo mus rau ⅳ + oxidation xeev.
Hauv cov txheej txheem tsim khoom, vanadium pentoxide flake feem ntau yog ua los ntawm cov txheej txheem txheej txheem nyuaj. Cov kauj ruam no muaj xws li raw khoom pretreatment, roasting, vanadium kua nag lossis daus thiab crystallization, vanadate decomposition, ziab thiab smelting. Ntawm lawv, ziab thiab smelting yog cov kauj ruam tseem ceeb. Los ntawm kev tswj qhov kub, siab thiab lwm yam kev mob, vanadate yog decomposed thiab hloov mus rau hauv vanadium pentoxide, thiab tom qab ntawd cov khoom flaky yog tau los ntawm smelting.
Flake vanadium pentoxide yog siv dav hauv ntau lub teb. Nyob rau hauv kev lag luam metallurgical, nws yog tsuas yog siv los ua ib qho alloy additive rau smelting ferrovanadium. Hauv kev lag luam tshuaj, nws yog ib qho tseem ceeb catalyst rau ntau cov tshuaj tiv thaiv, xws li kev tsim cov sulfuric acid, hluavtaws roj hmab thiab yas. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov iav tshwj xeeb, xws li cov iav uas muaj kev kub siab thiab kub kub, iav kho qhov muag thiab cov iav xim. Hauv kev lag luam ceramic, flaky vanadium pentoxide tuaj yeem siv los ua cov ntaub ntawv ceramic thiab coatings, uas tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion kuj ntawm cov ntaub ntawv.
Hauv kev lag luam hluav taws xob, nws yog siv los tsim cov khoom siv hluav taws xob, xws li transistors thiab kev sib xyaw ua ke, thiab nws tseem tuaj yeem siv los tsim cov hnub ci vaj huam sib luag los txhim kho cov roj teeb kom zoo. Hauv kev tiv thaiv ib puag ncig, vanadium pentoxide tuaj yeem siv los kho cov pa phem xws li cov pa khib nyiab, dej khib nyiab thiab khib nyiab, thiab tseem tuaj yeem siv los tsim cov khoom tiv thaiv ib puag ncig, xws li roj teeb vanadium. Hauv kev kho mob, nws tuaj yeem siv los tsim cov khoom siv kho mob thiab tshuaj.
