Tshem Tawm Ntawm Vanadium Impurities hauv Titanium

Qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm cov titanium raj thiab vanadium impurities yog me me. Piv txwv li, qhov sib txawv ntawm qhov sib txawv ntawm ob yam ntawm titanium raj-VOCl3 series yog 10 degree , thiab cov txheeb ze volatility d=1.22; thaum lub TC4 titanium alloy tube-VCl4 series ob yam Qhov kub ntawm qhov sib txawv yog 14 degrees Celsius. Txawm li cas los xij, nws muaj peev xwm siv txoj hauv kev siv lub cev los tshem tawm vanadium impurities, xws li siv cov kab ua kom muaj txiaj ntsig zoo kom tshem tawm vanadium. Qhov zoo ntawm txoj kev no yog tias nws tsis tas yuav siv cov tshuaj reagents, cov txheej txheem refining yog tas mus li thiab yooj yim rau automate, thiab cais VOCl3 thiab VCl4 tuaj yeem siv ncaj qha. Qhov tsis zoo yog kev siv hluav taws xob loj, cov cuab yeej siv loj loj, thiab kev xav tau los daws cov qauv ntawm lub hwj chim loj, uas tseem tsis tau siv rau hauv kev lag luam.

Tsis tas li ntawd, cov ntsiab lus khov ntawm ob lub ntsiab lus ntawm TC4 titanium alloy tube-V0Cl3 series txawv heev, txog 54 degrees Celsius. Yog li ntawd, txoj kev khov crystallization tuaj yeem siv los tshem tawm VOCI3. Txawm li cas los xij, khov siv ntau lub zog, yog li nws tsis tau siv rau kev lag luam. Vim li no, cov txheej txheem tshuaj feem ntau siv los tshem tawm vanadium. Kev tshem tawm cov tshuaj vanadium yog ntxiv cov tshuaj reagent rau titanium raj kom xaiv los txo lossis ua kom cov VOCl3 (los yog VCl4) impurity los tsim cov alum tsis sib xyaw uas cuam tshuam nrog TC4 titanium alloy raj. Kev sib cais yog xaiv adsorption ntawm VoCl3 (los yog VCl4) kom cais cov vanadium impurities thiab TC4 titanium alloy raj ntawm ib leeg; los yog xaiv kev sib cais ntawm VOCl2 kom cais cov alum impurities thiab 7icld ntawm ib leeg. Nws tuaj yeem hais tau tias cov txheej txheem tshem tawm vanadium zoo tshaj plaws nrog cov txheej txheem yooj yim, siv tau ntev, cov txheej txheem nqi qis, kev ua haujlwm zoo, thiab kev siv yooj yim ntawm kev ua haujlwm tsis tu ncua tseem tsis tau tsim. Qhov no kuj yog ib lub ntsiab lus uas yuav tsum tau kawm nyob rau hauv lub refining txheej txheem ntawm TC4 titanium alloy raj.
