Kev ntsuam xyuas cov ntsiab lus hauv cov hlau ore

Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam thiab kev txhim kho txuas ntxiv ntawm kev sib raug zoo, cov ntaub ntawv steel tau dhau los ua cov peev txheej tseem ceeb rau kev txhim kho hauv tebchaws. Lub smelting ntawm steel cov ntaub ntawv nyob rau hauv lub steel kev lag luam yog lub ntsiab theem ntawm rational siv cov ntaub ntawv. Txhua yam ntawm tib neeg lub neej yuav tsum tau saib xyuas cov khoom siv thiab qee cov khoom siv. Txoj kev loj hlob ntawm ntau yam kev lag luam hauv peb lub teb chaws, xws li kev thauj mus los, hluav taws xob thiab ntau lwm yam lag luam, tau them nyiaj rau cov khoom siv hlau. Nrog rau kev txhim kho txuas ntxiv ntawm peb lub teb chaws kev lag luam, qhov kev thov rau cov khoom siv steel hauv kev lag luam hauv tsev tseem nce ntxiv. Txawm li cas los xij, cov ntsiab lus ntawm qee cov ntsiab lus hauv cov hlau tau dhau los ntawm lub teb chaws tus qauv cov ntsiab lus hauv programmer. Yog li ntawd, nyob rau hauv kev lag luam thoob ntiaj teb, qhov kev thov rau cov hlau ore Kev tshawb nrhiav ntawm ntau lub ntsiab lus tau dhau los ua qhov txuas tseem ceeb heev. Yog li ntawd, siv txoj kev tshuaj xyuas sai thiab nyab xeeb yog lub hom phiaj rau cov neeg ua haujlwm tshuaj xyuas cov hlau ore.

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

Cov chaw soj ntsuam cov hlau ore ntau tshaj plaws hauv kuv lub tebchaws siv txoj kev txo qis ntawm titanium trichloride txhawm rau txheeb xyuas cov ntsiab lus hlau hauv cov hlau ore. Txoj kev tshawb nrhiav no hu ua chemical method. Txoj kev tshuaj no tsis tsuas yog kuaj pom cov ntsiab lus hauv cov hlau ore tab sis kuj tseem siv cov wavelength dispersive X-ray fluorescence spectroscopy los txiav txim cov ntsiab lus ntawm silicon, calcium, manganese thiab lwm yam hauv cov hlau ore. Txoj kev tshawb nrhiav rau ntau lub ntsiab lus hu ua X-ray fluorescence spectrometry nrhiav kom tau txoj kev. Thaum kuaj pom ntau yam hauv cov hlau ore, cov ntsiab lus hlau tag nrho tuaj yeem kuaj pom. Qhov zoo ntawm qhov no yog tias hauv txhua qhov kev tshawb nrhiav, ob lub ntsiab lus hlau yuav tau txais, thiab ob cov ntaub ntawv sib txawv heev hauv cov ntaub ntawv muaj nuj nqis. Me me, tab sis kuj tseem muaj qhov sib txawv me me uas txawv heev. Txoj kev sim siv hauv chav kuaj yuav tsum raug xaiv raws li cov hlau ore sib txawv, vim tias kuv lub teb chaws siv cov txheej txheem tshuaj raws li ib txoj hauv kev, 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 ore hauv kuv lub tebchaws. Txoj kev tshuaj xyuas yog xaiv raws li cov qauv sib txawv ntawm cov hlau ore kom tsim nyog thiab kev tshawb fawb. Kev faib tawm ntawm cov hlau ore hauv Suav teb yog qhov tawg thiab qhov chaw cia yog me me. Qhov zoo yog tsis ruaj khov nyob rau hauv ntau qhov chaw. Muaj ntau qhov sib txawv ntawm cov neeg txawv teb chaws. Txawv teb chaws hlau ore yog faib heev concentratedly, muaj ib tug kuj loj cia cheeb tsam, thiab yog ruaj khov zoo heev piv rau peb lub teb chaws.

Nrog rau kev txhim kho txuas ntxiv ntawm peb txoj kev lag luam, kev txhim kho thev naus laus zis ntawm cov chaw kuaj sim thiab kev nthuav dav ntxiv ntawm lawv cov kev pabcuam kev tshaj tawm tau nce kev lag luam ntau ntawm cov khoom kuaj kuaj, kom lawv muaj peev txheej txaus los ua kev sim. Peb lub teb chaws lub chaw soj nstuam yuav tsum tau sim ntau txhiab tus batch ntawm kev lag luam tau ntxiv rau cov ntaub ntawv tshawb nrhiav. Nrog kev nce ntxiv hauv kev tshawb nrhiav cov hlau ore hauv peb lub tebchaws, cov qauv yuav tsum tau qhuav thaum kuaj tshuaj. Txhua txoj kev ziab yuav tsum tau ua haujlwm ntawm tes. Thaum lub sij hawm tag nrho cov txheej txheem, ntawm ib sab, kev khiav hauj lwm Cov neeg ua hauj lwm tau mob siab rau ua kom tiav txhua qhov txuas. Yog tias qhov no tshwm sim rau lub sijhawm ntev, cov neeg ua haujlwm lub cev yuav tsis tau txais kev so zoo thiab yuav nyob rau hauv lub xeev ntawm overload, uas yuav ua rau poob ntawm kev ua haujlwm zoo. Nyob rau hauv cov nqe lus ntawm nws nrhiav tau, nws yog heev uas yuav muaj ib co teeb meem raws sij hawm yuav tshwm sim. Ntawm qhov tod tes, thaum lub sijhawm ua haujlwm, kev siv dej, hluav taws xob thiab kev siv qee yam tshuaj muaj kev cuam tshuam zoo heev thiab ua rau ib puag ncig tsis zoo nyob rau hauv ib qho chaw. Nyob rau tib lub sijhawm, cov pa roj thiab cov dej khib nyiab tsis tuaj yeem kho tau zoo. Yog li Nws yog ib qho tseem ceeb heev los txhim kho kev tshawb nrhiav kom pom cov ntaub ntawv kom raug. Peb lub teb chaws lub chaw soj nstuam tau sim cov hlau ore tau ntau xyoo, thiab tau ua tiav ntau yam kev sim thiab ntau cov ntaub ntawv xeem. Cov ntaub ntawv no yog ua raws li cov txheej txheem tshuaj thiab X-ray fluorescence spectroscopy. Los ntawm kev txheeb xyuas cov ntaub ntawv no, peb tuaj yeem nrhiav X-ray fluorescence. Spectroscopy yog ib txoj hauv kev tshiab uas tuaj yeem hloov cov tshuaj. 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

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

Lub hauv paus ntsiab lus ntawm X-ray fluorescence spectroscopy yog thawj zaug siv anhydrous lithium tetraborate ua flux, lithium nitrate ua oxidant, thiab potassium bromide ua tus tso tawm los npaj ib qho qauv, thiab tom qab ntawd ntsuas X-ray fluorescence spectrum siv tus nqi hauv lub caij hlau ua kom muaj kev sib raug zoo yog tsim los ntawm cov ntsiab lus. Xam cov ntsiab lus ntawm cov hlau hauv hlau ore.

Cov reagents thiab cov cuab yeej siv hauv X-ray fluorescence spectroscopy sim yog cov dej distilled, hydrochloric acid, anhydrous lithium tetraborate, lithium nitrate, potassium bromide thiab gases. Cov cuab yeej siv yog X-ray fluorescence spectrometer.

Hauv ntau lub tebchaws, feem ntau siv txoj hauv kev los kuaj xyuas cov ntsiab lus hauv cov hlau ore yog X-ray fluorescence spectroscopy. Kev tshawb pom ntawm txoj kev no tsuas yog tsom mus rau kev tsom xam ntawm cov txheej txheem hauv paus ntsiab lus, thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem uas twb muaj lawm kom ua tau raws li qhov yuav tsum tau muaj ntawm kev tshawb pom tseeb. Thaum ua qhov kev ntsuam xyuas, feem ntau me me ntawm cov qauv kev daws teeb meem yog siv los ua qhov kev ntsuam xyuas tsim nyog ntawm txoj kev kuaj pom. kev soj ntsuam. Txij li thaum cov hlau ore nyob rau hauv qhov kev sim yog txawv heev ntawm cov hlau ore nyob rau hauv tus qauv qauv nyob rau hauv cov nqe lus ntawm cov duab, tshuaj muaj pes tsawg leeg, thiab lwm yam., X-ray fluorescence spectrometry txoj kev tsis yog heev meej nyob rau hauv lub soj ntsuam txheej txheem. Qhov tseeb yog ua tiav los ntawm kev txheeb xyuas ntau cov ntaub ntawv khaws tseg thaum lub sij hawm tshawb nrhiav cov hlau ore los ntawm cov txheej txheem tshuaj thiab X-ray fluorescence spectrometry hauv kev sim, thiab tom qab ntawd txheeb xyuas cov ntaub ntawv, thiab sib piv qhov sib txawv ntawm ob txoj kev tshawb nrhiav los ntawm kev tshuaj xyuas. Nrhiav kev sib raug zoo ntawm ob qho tib si tuaj yeem txo cov tib neeg thiab nyiaj txiag kev nqis peev hauv kev tshuaj xyuas mus rau qhov zoo. Nws kuj tseem tuaj yeem txo cov pa phem ib puag ncig, ua rau tib neeg lub neej yooj yim dua, thiab tsim kom muaj txiaj ntsig kev lag luam ntau dua rau kuv lub teb chaws kev lag luam steel.

Shandong Hengbiao Kev Tshawb Fawb thiab Kev Ntsuas Co., Ltd.yog lub tsev kawm ntawv xeem nrog ob qhov kev tsim nyog C uas tau dhau qhov kev lees paub ntawm kev tshuaj ntsuam xyuas thiab kev xeem thiab Tuam Tshoj National Accreditation Service for Conformity Assessment.
