Khoom Description
Hauv thaj chaw ntawm cov ntaub ntawv, vanadium nitrogen alloys tuav txoj haujlwm tseem ceeb vim lawv cov khoom tshwj xeeb. Yuav kom nkag siab txog cov txheej txheem yug me nyuam ntawm cov khoom siv yees siv no, ib tus yuav tsum tau nkag siab txog nws txoj kev tsim khoom zoo thiab zoo heev.
Tag nrho cov txheej txheem tsim khoom yog zoo li ua tib zoo ua las voos, nrog rau txhua kauj ruam txuas nrog thiab tseem ceeb. Los ntawm kev xaiv thiab ua cov khoom siv raw rau kev tswj xyuas meej ntawm txhua theem cov tshuaj tiv thaiv, yuav tsum muaj kev paub txog qib siab thiab kev ua haujlwm zoo heev.
Cov kws tshawb fawb thiab cov kws ua haujlwm niaj hnub tshawb nrhiav thiab tsim kho tshiab hauv cov txheej txheem no, sib zog ua kom zoo dua txhua yam los txhim kho kev tsim khoom thiab cov khoom zoo. Lawv xyuas kom meej qhov kev ua tau zoo thiab kev ruaj ntseg ntawm nws los ntawm kev tswj hwm yam xws li kub, cua, thiab cov khoom siv raw.
Cov khoom tsim tawm
Ua ntej, thawj kauj ruam hauv kev tsim vanadium nitrogen alloys yog pub lim ncuav mog qab zib ammonium vanadate nrog cov dej noo ntawm 20-30% rau hauv lub tshuab ziab khaub ncaws. Ntawm no, nws ua tau raws li cov pa tso pa tawm los ntawm Stoke rauv (kub ntau ntawm 300-400 degree) los tsim cov roj av-khoom sib xyaw ua ke. Los ntawm txoj kev ziab no, lub ncuav mog qab zib lim zoo li ammonium vanadate tau ua tiav rau hauv cov hmoov qhuav. Cov txheej txheem ziab no yog qhov tseem ceeb vim nws nteg lub hauv paus rau cov tshuaj tiv thaiv tom ntej.
Tom qab ntawd, cov hmoov qhuav no tau xa mus rau Stoke calcination rauv. Nyob rau hauv qhov kub thiab txias ib puag ncig ntawm 700-900 degree, qhuav hmoov tau dhau los ua ib qho tseem ceeb ntawm kev tshem tawm ammonia, uas ua rau lub cim ntawm vanadium hmoov nrog cov ntsiab lus ntau dua 96%. Qhov no yog ib qho tseem ceeb ntawm kev hloov pauv theem, uas yuav siv sij hawm ib kauj ruam tseem ceeb rau kev taw qhia ntawm nws.
Tom ntej no, vanadium hmoov yuav ntxiv nrog cov ntaub ntawv raw xws li carbon hmoov activator thiab ua rau hauv cov khoom. Qhov no zoo li yooj yim pob ua txheej txheem tiag tiag yuav ua tib zoo tswj cov khoom sib xws thiab cov tshuaj tiv thaiv.
Thaum kawg, cov khoom kheej kheej no tau muab tso rau hauv qhov chaw tsis tu ncua ob lub laub phaj siab-kub rauv. Raws li kev tiv thaiv ntawm atmospheric siab thiab nitrogen cua, lawv raug txo qis cov tshuaj tiv thaiv ntawm qhov kub ntawm 1400-17000 degree . Hauv cov txheej txheem no, ntau lub ntsiab lus thiab cov tebchaw sib cuam tshuam thiab hloov pauv, thaum kawg ua rau tsim cov vanadium nitrogen alloy peb xav tau.
