Muaj Txoj Kev Rau Cov Tshuaj Tshem Tawm Ntawm Vanadium Impurities Los Ntawm Titanium Tubing

Vanadium impurities nyob rau hauv titanium tubing feem ntau yog VOCl3 thiab ib qho me me ntawm kev txiav txim siab VCI4, muaj qhov uas muab cov xim daj rau TC4 titanium alloy tubing. Lub hom phiaj ntawm refining vanadium tshem tawm tsis yog tsuas yog rau decolorization, tab sis kuj rau oxygen tshem tawm. Qhov no yog ib feem tseem ceeb heev ntawm cov txheej txheem refining.
Titanium tubes thiab vanadium impurities nug discretionary boiling point sib txawv thiab cov txheeb ze volatility kuj me me, xws li titanium hlab - VOCl3 system ntawm ob lub ntsiab ntawm boiling point sib txawv ntawm 10 degrees Celsius, tus txheeb ze volatility d=1.22; thiab TC4 titanium alloy raj - VCl4 system ntawm ob qhov sib txawv ntawm qhov kub ntawm 14 degrees Celsius. Txawm li cas los xij, kev hais lus theoretical, kev siv lub cev txoj hauv kev los tshem tawm vanadium impurities yog ua tau, xws li kev siv cov khoom siv hluav taws xob ntau ntxiv nrog rau vanadium. Qhov zoo ntawm txoj kev no yog tsis tas yuav siv tshuaj reagents, refining txheej txheem ko taw nruam ntau lawm, yooj yim kom paub automation, cais VOCl3 thiab VCl4 tuaj yeem siv ncaj qha. Qhov tsis zoo yog tias kev siv hluav taws xob, khoom siv peev txheej, tab sis kuj yuav tsum tau daws cov qauv ntawm lub hwj chim loj, muab tso rau hauv kev lag luam tseem tsis tau siv.

Tsis tas li ntawd, TC4 titanium alloy tube - V0Cl3 system ntawm ob lub ntsiab lus ntawm qhov sib txawv ntawm qhov sib txawv yog qhov loj, txog 54 degrees Celsius sib txawv, yog li tuaj yeem siv ntxiv rau txoj kev khov crystallization ntawm VOCI3 tab sis khov siv. ntau lub zog, yog li nws tseem tsis tau txais kev thov kev lag luam. Rau qhov no feem ntau siv tshuaj txoj kev ntxiv rau vanadium, cov txheej txheem tshuaj ntxiv rau vanadium yog cov tshuaj reagent ntxiv rau titanium raj, kom VOCl3 (los yog VCl4) impurities xaiv txo los yog xaiv los nag los tsim cov tshuaj alum tsis sib haum thiab TC4 titanium raj sib cais. los ntawm ib leeg los yog xaiv adsorption ntawm VoCl3 (los yog VCl4), kom cov vanadium impurities thiab TC4 titanium raj sib cais los ntawm ib leeg; los yog xaiv kev sib cais ntawm VOCl2, kom cov alum impurities thiab 7ic alloy raj. alum impurities thiab 7icld cais ntawm ib leeg. Nws tuaj yeem hais tias cov txheej txheem zoo tshaj plaws cov cuab yeej siv tau yooj yim ntev tus nqi qis, kev ua haujlwm zoo, tab sis kuj yooj yim kom paub txog kev ua haujlwm tas li ntawm cov txheej txheem tshem tawm vanadium tseem tsis tau tsim. Qhov no kuj yog TC4 titanium alloy raj refining txheej txheem yuav tsum tau kawm cov kev kawm.
