Kuyera kweSiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, uye K₂O kunodiwa kuti pave nekudzora kwakarurama zvivakwa zvechigadzirwa uye kutevedzera mitemo. Zvishandiso zveLonnmeter XRF zvinopa zviyero zvakarurama uye zvakananga zvezvikamu izvi zvakakosha.
Kuongorora kwakajairika kunoona kutsauka kwakaderera se0.01 wt% yema major oxides, zvichiita kuti vagadziri varambe vaine chinangwa chezvikamu zvegirazi. Mazinga eNa₂O kana CaO asina kunaka anogona kuchinja kuramba kupisa, kujeka, uye kugara kwenguva refu. Kudzora kwakasimba kunoderedza kurambwa kwebatch nekuda kweruvara rwusina kutsanangurwa kana kutadza kwemuchina.

Kuumbwa kweGirazi: Zvinhu uye Zvimwe Zvinhu
Magirazi anodarika 70% ekutengeserana anoumbwa ne silica (SiO₂), zvichiita kuti chimiro chive chakasimba uye chisarambe chichishanda nemakemikari. Soda (Na₂O), inowanzova 12–15%, inoderedza kunyunguduka, zvichivandudza kugadzirwa kwayo. Lime (CaO), inenge 9–12%, inowedzera kuomarara uye kugara kwenguva refu kwemakemikari. Alumina (Al₂O₃) pa1–3% inowedzera simba remuchina uye inovandudza kugadzikana kwekupisa. Magnesia (MgO) ne potash (K₂O) zvinoshandiswa muhuwandu hushoma pakugadzirisa viscosity uye hunhu hwepamusoro. Lead oxide (PbO), kana iripo pamusoro pe24%, inopa refractive index yakakwira uye density yakakura, yakakosha kumagirazi e optical ne lead.
Mhando dzezvinhu dzinotsanangurwa nezvinhu izvi zvemagirazi. Girazi reSoda-lime ndiro rinotonga kugadzirwa kwepasi rose nekuda kwehunhu hwemakanika nemakemikari hwakaringana. Girazi reBorosilicate, rine 10–13% B₂O₃, rinoita kuti pave nekupisa kushoma, kwakakosha pakushandiswa murabhoritari nemidziyo yekubikira. Girazi reLead rinonyanya kukosha pakujeka kwemaziso uye kupenya kwemidziyo yetafura. Magirazi eAluminosilicate anowedzera Al₂O₃ kuti igare kwenguva refu munzvimbo dzine hukasha. Kushanda kwemhando yega yega yegirazi kunoenderana nekudzora kwakaringana kwekugadzirwa kwezvinhu zvegirazi.
Magirazi Akasanganiswa, Magirazi Epurasitiki, uye Girazi Reupfu
Magirazi akasanganiswa anopa homogeneity yakanyanya uye kusasimba kwakanyanya, zvichipa mhedzisiro chaiyo mu XRF elemental analysis yekugadzirwa kwegirazi. Matrix yavo inofanana inobvisa micro-inhomogeneities, zvichiita kuti ive nechokwadi chekuyera zvakananga SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, uye K₂O.
Magirazi epellet anoshanda sezvinhu zvinovimbika zvekutarisa uye zviyero zvekuongorora mukugadzirwa kwegirazi. Anogonesa kuongororwa kwekuumbwa kwechinhu nekukurumidza uye anotsigira kuonekwa kwekuchinja kwebatch kana kusvibiswa muQA/QC labs. Magirazi epellets anochengetedza zvinhu zvakakosha zvekugadzirwa kwegirazi, zvichikurudzira kuteverwa kwese kwese kwekugadzirwa.
Girazi reupfu rinotsigira maforoma ekupenda, kubvisa mabara, kubatanidza makemikari, kudzokorodza, uye rinoita kuti rikurumidze kusanganiswa. Saizi yaro yakanaka inoita kuti zvinhu zvive zvakafanana, zvakakosha pakugadzirira sampuro. Mashandisirwo egirazi reupfu anoshanda mukugadzirwa kwezvinhu uye kugadzirwa kwechigadzirwa, zvichibvumira kutarisa kwakarurama kwekugadzirwa kwezvinhu zvegirazi uye kutsigira kuongororwa kwakananga uye kwakarurama kweXRF.

Kudzora Hunhu Mukugadzirwa Kwegirazi
Kudzora kunaka kwekugadzirwa kwegirazi kunoenderana neXRF kuti iongorore zvinhu zvakawanda, zvichisimbisa kuenderana kwechinhu chimwe nechimwe uye kudzivirira kusvibiswa. Masisitimu eLonnmeter XRF anoyera Si, Na, Ca, Mg, Al, K, Pb, nezvimwe zvinhu zvakakosha mumasekondi asingasviki makumi matanhatu. Maitiro ekuongorora eTXRF anoona zvinhu zvikuru nezvinotevera, zvakaita seMn, Ni, Cu, Zn, uye Sr, kusvika pamazinga epasi peppm.
Kutarisa zvinhu zvidiki zvinodzivirira ruvara rusingadiwe uye kushaya simba kwemuchina. Kuona huwandu hweFe, Ti, uye Pb kunotsigira kujeka kwemaziso uye kunobvisa njodzi dzinobva muzvinhu zvinosanganisirwa kana nzvimbo dzekushushikana. Kugadzira mapu echinhu, kunogoneswa neXRF-CT yepamusoro uye nzira dze confocal, kunosimbisa kufanana kwenzvimbo pakati pepepa kana girazi rakaumbwa, zvakakosha pakugadzirwa kukuru.
Midziyo yeXRF inotakurika uye iri mukati memota inoongorora nekukurumidza, ichibatanidza mhedzisiro mukudzora maitiro panguva chaiyo. Nzira iyi inovandudza vimbiso yemhando yekugadzira magirazi, ichitsigira kurongeka kwakasimba kwechigadzirwa uye mhinduro nekukurumidza kune kutsauka kwemaitiro.
Matekiniki ekuzivikanwa uye kusiyanisa mhando
Mhando dzenzira dzekuziva magirazi dzinosanganisira XRF spectral fingerprinting, density measurements, uye refractive index assessment. XRF spectral fingerprinting inopa zvakananga, isingaparadze elemental profiling yezvinhu zvese zvikuru zve glass composition, zvichibvumira kuonekwa kweSi, Na, Ca, Mg, Al, Pb, uye K nekudzokororwa kuri pasi pe3% RSD. Kuyerwa kwedensity kunobatsira kusiyanisa kuumbwa kwezvinhu zvegirazi zvine musiyano kubva pa2.2 g/cm³ (soda-lime) kusvika pamusoro pe3.1 g/cm³ (lead glass). Refractive index assessment inoparadzanisa soda-lime, borosilicate, uye lead glass nemazvo; typical nD values dzinotangira pa1.51 kusvika 1.70.
Kuongororwa kwenhamba kunovandudza kurongeka kwekuzivikanwa. K-inoreva kuunganidzwa kwezvikamu zvegirazi nezvikamu zvedata zveXRF zvakawanda, zvichitsigira huwandu hwekufananidza kirasi yekuongorora hunopfuura 95%. Kuongororwa kweGrey correlation kunoparadzanisa kuchinja kudiki asi kwakasiyana pakati pemabatch kana mavariants. Mamodheru eChemometric anoisa muzvikamu zvemagirazi (semuenzaniso, magirazi akasanganiswa negirazi rakakuyiwa) neminwe ye elemental ine kururama kunopfuura 98% kana yakabatanidzwa nedata reXRF.
Kuvimbiswa Kwemhando Yekugadzira Magirazi
Kuvimbiswa kwemhando yegirazi kunoenderana nekuonekwa nekukurumidza uye nemazvo kwezvinhu zvakawanda. Vaongorori veXRF vari mumutsara uye murabhoritari vanoongorora kuumbwa kwezvinhu zvegirazi mukati memasekonzi mashoma. X-ray fluorescence inoratidza SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, naK₂O, zvichitsigira kutonga pamusoro pezvinhu zvekugadzirwa kwegirazi uye kufanana kwebatch.
Zvichienderana nedata reindasitiri, XRF inosvika pamiganho yekuona kusvika pa1 ppm yezvinhu zvidiki, zvichigonesa kuona tsvina inokuvadza zvinhu kana runako. Kushandiswa kweXRF kunobvumira mhinduro yakananga yekugadzirisa maitiro, zvichiwedzera goho kusvika ku15% mumitsetse inodzorwa zvakanyanya.
Kuronga otomatiki kunobatanidzwa nekugadzirwa, zvichiita kuti girazi rirambe richiongororwa. Izvi zvinoderedza kusiyana kwemhando dzakasiyana-siyana uye zvinobvisa zvinhu zvisina kunyatsotsanangurwa. Kuongororwa kwezvinhu zvakawanda kwakakosha paQA yehunhu hwemagirazi akasanganiswa, mashandisirwo emagirazi, uye mashandisirwo emagirazi eupfu. Kuongorora kwakazara panzvimbo kunoderedza nguva yekushanda uye kunogonesa kugadziriswa nekukurumidza, zvichitsigira kunaka kwechigadzirwa.
Gadzirisa Mafambiro Ako Ekuongorora Girazi
Vaongorori veLonnmeter XRF vanopa chiyero chakarurama chezvinhu zvakakosha pakuumbwa kwegirazi: SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, K₂O. Zvishandiso izvi zvinopa ruzivo rwezvinhu zvakawanda zvekusimbisa mhando yekugadzira magirazi uye kusimbisa nekukurumidza magirazi akasanganiswa, magirazi epellets, uye magirazi eupfu. Kuti uongorore magirazi ako nenzira yepamusoro, gadzirisa magirazi ako.Muchina weXRFkutsigira zvinodiwa zvakasiyana-siyana mukugadzira magirazi uye nzira dzekuona.
