Raws li peb txhua tus paub, muaj ntau yam cuam tshuamtungsten hmoovcov cuab yeej, tab sis cov ntsiab lus tseem ceeb tsis muaj dab tsi ntau tshaj li cov txheej txheem ntawm cov hmoov tungsten, cov khoom thiab cov yam ntxwv ntawm cov khoom siv raw. Tam sim no, ntau yam kev tshawb fawb nyob rau hauv cov txheej txheem txo, xws li txo qhov kub thiab txias, lub nkoj thawb ceev, loading muaj peev xwm thiab txoj kev, txo cua sov, thiab lwm yam. Thaum lub sij hawm tsim thiab kev tshawb fawb txheej txheem, cov kws tshawb fawb tau pom tias cov khoom sib txawv ntawm tungsten oxide raw cov ntaub ntawv muaj ib tug cuam ​​tshuam rau kev ua haujlwm ntawm tungsten hmoov.

Cia peb saib cov khoom ntawm tungsten oxide raw khoom (daj tungsten oxide WO3, xiav tungsten oxide WO2.98, ntshav tungsten oxide WO2.72 thiab tungsten dioxide WO2) ntawm cov khoom ntawm tungsten hmoov.

1. Qhov sib txawv ntawm cov yam ntxwv ntawm cov khoom sib txawv tungsten oxide raw khoom ncaj qha txiav txim siab qhov loj thiab muaj pes tsawg leeg ntawm tungsten hmoov, nws lub cev muaj zog xws li compactability thiab moldability, cov ntsiab lus ntawm impurity ntsiab, thiab morphology thiab qauv ntawm tungsten hmoov. Hauv kev tsim khoom tiag tiag, cov khoom siv raw yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm tungsten hmoov thaum xaiv cov khoom siv raw, uas yuav pab ua kom cov khoom zoo thiab ua tiav cov txiaj ntsig zoo.

2. Cov ntsiab lus oxygen hauv cov khoom siv raw ntawm tungsten oxide yog qhov zoo sib xws nrog Fsss ntawm tungsten hmoov. Cov ntshav tungsten oxide nrog cov ntsiab lus qis dua yuav tsum raug xaiv los ua cov khoom siv raw rau kev tsim cov hmoov ultrafine tungsten, thiab cov xim daj nrog cov ntsiab lus oxygen siab yuav tsum raug xaiv rau kev tsim cov coarser tungsten hmoov. Tungsten oxide thiab xiav tungsten oxide yog siv los ua raw khoom.

3. Lub zog particle qauv ntawm tungsten oxide raw khoom, qhov qeeb qeeb ntawm tus nqi txo, lub coarser tungsten hmoov tsim, thiab qhov dav ntawm particle loj tis. Txhawm rau tsim cov hmoov tungsten nrog cov ntsiab lus siab, nws raug nquahu kom xaiv cov khoom siv oxide nrog ib qho khoom siv raw theem muaj pes tsawg leeg thiab cov qauv xoob xoob thiab cov khoom sib xws.

4. Rau kev tsim cov khoom siv tungsten thiab cov khoom siv tungsten nrog kev ua haujlwm tshwj xeeb, nws yog qhov zoo dua los xaiv cov khoom tshwj xeeb uas kho tungsten oxide lossis ntshav tungsten oxide raws li cov khoom siv raw.

Pure tungsten hmoov tuaj yeem ua rau cov ntaub ntawv ua tiav xws li cov xov hlau, rods, raj, daim hlau thiab cov khoom siv nrog qee yam duab. Tsis tas li ntawd, tungsten hmoov tov nrog lwm cov hmoov hlau kuj tuaj yeem ua rau ntau yam tungsten alloys, xws li tungsten-molybdenum alloy, tungsten rhenium alloy, tungsten tooj liab alloy thiab high-density tungsten alloy.
