Nrog rau kev txhim kho tas mus li ntawm kev lag luam thiab kev txhim kho tas mus li ntawm kev sib raug zoo, cov ntaub ntawv hlau tau dhau los ua qhov chaw tseem ceeb rau kev txhim kho hauv tebchaws. Kev smelting ntawm cov ntaub ntawv hlau hauv kev lag luam hlau yog theem tseem ceeb ntawm kev siv cov ntaub ntawv kom zoo. Txhua yam ntawm tib neeg lub neej xav tau kev saib xyuas rau cov ntaub ntawv tsim kho thiab qee cov ntaub ntawv ua haujlwm. Kev txhim kho ntawm ntau yam kev lag luam hauv peb lub tebchaws, xws li kev thauj mus los, hluav taws xob thiab ntau lwm yam kev lag luam, tab tom them sai rau cov ntaub ntawv hlau. Nrog rau kev txhim kho tas mus li ntawm peb lub tebchaws kev lag luam, qhov kev thov rau cov ntaub ntawv hlau hauv kev lag luam hauv tsev txuas ntxiv nce ntxiv. Txawm li cas los xij, cov ntsiab lus ntawm qee cov ntsiab lus hauv hlau tau dhau qhov ntsuas tus qauv hauv tebchaws hauv tus programmer. Yog li ntawd, hauv kev lag luam thoob ntiaj teb, qhov kev thov rau hlau ore Kev tshawb pom ntawm ntau yam ntsiab lus tau dhau los ua qhov txuas tseem ceeb heev. Yog li ntawd, kev siv txoj kev tshuaj xyuas sai thiab muaj kev nyab xeeb yog lub hom phiaj sib xws rau cov neeg ua haujlwm tshuaj xyuas hlau ore.

Cov xwm txheej tam sim no ntawm kev sim cov ntsiab lus dav dav hauv cov hlau ore hauv kuv lub tebchaws

Cov chaw kuaj hlau feem ntau hauv kuv lub tebchaws siv txoj kev txo qis ntawm titanium trichloride los ntes cov ntsiab lus hlau hauv cov hlau. Txoj kev kuaj no hu ua txoj kev tshuaj lom neeg. Txoj kev tshuaj lom neeg no tsis yog tsuas yog ntes cov ntsiab lus hauv cov hlau xwb tab sis kuj siv cov wavelength dispersive X-ray fluorescence spectroscopy los txiav txim siab cov ntsiab lus ntawm silicon, calcium, manganese thiab lwm yam ntsiab lus hauv cov hlau. Txoj kev kuaj rau ntau yam ntsiab lus hu ua X-ray fluorescence spectrometry detection method. Thaum ntes ntau yam ntsiab lus hauv cov hlau, cov ntsiab lus hlau tag nrho kuj tuaj yeem ntes tau. Qhov zoo ntawm qhov no yog tias hauv txhua qhov kev kuaj, ob cov ntaub ntawv ntsiab lus hlau yuav tau txais, thiab ob cov ntaub ntawv sib txawv heev hauv cov nqi ntaub ntawv. Me me, tab sis kuj muaj qee qhov sib txawv me me uas sib txawv heev. Txoj kev kuaj siv hauv chaw kuaj yuav tsum tau xaiv raws li cov hlau sib txawv, vim tias kuv lub tebchaws siv cov txheej txheem tshuaj lom neeg ua ib txoj kev siv, thiab nws ua lub luag haujlwm tseem ceeb. Ib qho laj thawj loj yog tias Kev xaiv yog raws li cov yam ntxwv ntawm cov hlau hauv kuv lub tebchaws. Txoj kev tshuaj xyuas raug xaiv raws li cov yam ntxwv sib txawv ntawm cov hlau ore kom tsim nyog thiab tshawb fawb. Kev faib tawm ntawm cov hlau ore hauv Suav teb yog qhov sib txawv thiab thaj chaw khaws khoom me me. Qhov zoo tsis ruaj khov hauv ntau qhov chaw. Muaj ntau qhov sib txawv ntawm cov neeg txawv teb chaws. Cov hlau ore txawv teb chaws tau faib ntau heev, muaj thaj chaw khaws khoom loj, thiab muaj qhov zoo ruaj khov piv rau peb lub tebchaws.

Nrog rau kev txhim kho tas mus li ntawm peb txoj kev lag luam, kev txhim kho thev naus laus zis ntawm cov chaw kuaj mob thiab kev nthuav dav tas mus li ntawm lawv cov kev pabcuam tshaj tawm tau ua rau muaj kev lag luam ntau ntxiv ntawm cov khoom kuaj mob, yog li lawv muaj cov peev txheej txaus los ua kev sim. Peb lub tebchaws cov chaw kuaj mob yuav tsum tau sim ntau txhiab tus neeg ua haujlwm tau ntxiv rau cov ntaub ntawv kuaj mob. Nrog rau kev nce ntxiv tas mus li ntawm kev kuaj mob ntawm cov hlau ore hauv peb lub tebchaws, cov qauv yuav tsum tau ziab thaum lub sijhawm kuaj tshuaj. Txhua txoj kev ziab yuav tsum tau ua haujlwm tes. Thaum lub sijhawm tag nrho cov txheej txheem, ntawm ib sab tes, kev ua haujlwm Cov neeg ua haujlwm tau cog lus tag nrho los ua kom zoo tag nrho txhua qhov txuas. Yog tias qhov no tshwm sim ntev, lub cev ntawm cov neeg ua haujlwm yuav tsis tau so zoo thiab yuav nyob rau hauv lub xeev ntawm kev thauj khoom ntau dhau, uas yuav ua rau kev poob qis ntawm qhov zoo ntawm txoj haujlwm. Hauv nws qhov kev kuaj mob, nws muaj peev xwm heev tias qee qhov teeb meem tsis tu ncua yuav tshwm sim. Ntawm qhov tod tes, thaum lub sijhawm ua haujlwm, kev siv dej, hluav taws xob thiab kev siv qee cov tshuaj tau cuam tshuam loj heev thiab ua puas tsuaj rau ib puag ncig hauv qee qhov ntau. Tib lub sijhawm, cov pa roj thiab dej khib nyiab tsis tuaj yeem kho tau zoo. Yog li Nws yog ib qho tseem ceeb heev los txhim kho kev ua haujlwm ntawm kev kuaj mob kom ua rau cov ntaub ntawv kuaj mob raug dua. Peb lub teb chaws cov chaw soj nstuam tau sim cov hlau ore tau ntau xyoo, thiab tau paub ntau yam kev paub dhau los ntawm kev sim thiab ntau cov ntaub ntawv sim. Cov ntaub ntawv no yog raws li cov txheej txheem tshuaj lom neeg thiab X-ray fluorescence spectroscopy. Los ntawm kev tshuaj xyuas cov ntaub ntawv no, peb tuaj yeem nrhiav tau X-ray fluorescence. Spectroscopy yog ib txoj hauv kev tshiab uas tuaj yeem hloov cov txheej txheem tshuaj lom neeg. Qhov zoo ntawm qhov no yog tias nws tuaj yeem txuag tau ntau tus neeg ua haujlwm thiab cov peev txheej nyiaj txiag thiab txo cov pa phem ib puag ncig.

01

Txoj cai tshuaj xyuas txoj kev X-fluorescence thiab cov kauj ruam tshuaj xyuas

Lub hauv paus ntsiab lus ntawm X-ray fluorescence spectroscopy yog siv thawj zaug anhydrous lithium tetraborate ua ib qho flux, lithium nitrate ua ib qho oxidant, thiab potassium bromide ua ib qho tso tawm tus neeg sawv cev los npaj ib daim qauv, thiab tom qab ntawd ntsuas qhov X-ray fluorescence spectrum intensity value hauv cov hlau kom ua rau nws muaj kev sib raug zoo ntawm cov ntsiab lus ntawm cov ntsiab lus.
