Te Hanganga o te Karāhe: Ngā Huānga me ngā Rerekētanga Rauemi
Neke atu i te 70% o te karāhe arumoni he silica (SiO₂), e whakarato ana i te pakari hanganga me te ātete matū. Ko te houra (Na₂O), te nuinga o te 12–15%, ka whakaiti i te ira rewa, ka whakapai ake i te kaha hanga. Ko te raima (CaO), tata ki te 9–12%, ka whakanui ake i te pakeke me te roa o te matū. Ko te alumina (Al₂O₃) i te 1–3% ka whakarei ake i te kaha miihini me te whakapai ake i te pumau wera. Ko te konupora (MgO) me te pāhare pākawa (K₂O) ka whakamahia i roto i ngā rahinga iti ake hei whakatikatika i te matotoru me ngā āhuatanga o te mata. Ko te waikura mata (PbO), ina neke atu i te 24%, ka whakawhiwhia he taupū whakaata teitei me te kiato nui ake, he mea nui mō te karāhe whatu me te mata.
Ko ngā momo rauemi e tautuhia ana e ēnei huānga o te hanganga karāhe. Ko te karāhe houra-raima te mea nui rawa atu o te hanga o te ao nā te taurite o ngā āhuatanga ā-pūkaha me te matū. Ko te karāhe borosilicate, kei roto ko te 10–13% B₂O₃, ka taea te whakaiti i te whānui o te wera, he mea nui mō ngā tono taiwhanga me ngā taputapu tunu kai. Ko te karāhe mata te mea nui ki te māramatanga whatu me te kanapa mō ngā taputapu tēpu. Ko ngā whakakapinga karāhe aluminosilicate kua whakanuia te Al₂O₃ mō te roa o te mau i roto i ngā taiao kaha. Ko te mahi o ia momo karāhe e whakawhirinaki ana ki te whakahaere tika i te hanganga o ngā rauemi karāhe.
Ngā Pīra Karāhe Kua Whakakotahitia, Ngā Pēreti Karāhe, me te Paura Karāhe
He tino ōrite te āhua o ngā pīrere karāhe hanumi, ā, he iti noa iho te mimiti, e whakarato ana i ngā hua tika i roto i te tātaritanga huānga XRF o te hanga karāhe. Mā te hanganga ōrite ka whakakorea ngā āhua moroiti-kore ōrite, ka whakarite kia tika te ine i te SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, me te K₂O.
He rauemi tohutoro pono, he paerewa whakatikatika hoki ngā pire karāhe i roto i ngā tukanga whakahaere kounga whakaputa karāhe. Mā ēnei ka taea te tātari tere i ngā hanganga, ā, ka tautoko i te kitenga i ngā rerekētanga puranga, i ngā poke rānei i roto i ngā taiwhanga QA/QC. Kei roto i ngā pire ngā āhuatanga matua o te hanganga karāhe, e whakatairanga ana i te whai i ngā tukanga whakaputa puta noa i te ao.
Ka tautoko te karāhe paura i ngā hanganga mō ngā paninga, ngā mea whakakoi, te puranga matū, te hangarua, ā, ka āwhina i te hanumi tere. Mā tōna rahi matūriki pai ka whakarite kia ōrite katoa ngā huānga, he mea nui mō te whakarite tauira māngai. Ka horapa ngā tono karāhe paura ki te tukanga me te whanaketanga hua, ka taea te aroturuki tika i te hanganga o ngā rauemi karāhe me te tautoko i te tātaritanga XRF tika, tika.

Te Mana Kounga i roto i te Hanga Karāhe
Ko te mana whakahaere kounga o te hanga karāhe e whakawhirinaki ana ki te XRF mō ngā tirotiro maha-huānga, e whakaū ana i te ōritetanga o te puranga-ki-te-puranga me te karo i te poke. Ka inehia e ngā pūnaha Lonnmeter XRF te Si, Na, Ca, Mg, Al, K, Pb, me ētahi atu huānga nui i roto i te iti iho i te 60 hēkona. Ka kitea e ngā tikanga tātari TXRF ngā huānga nui me ngā huānga iti, pērā i te Mn, Ni, Cu, Zn, me te Sr, ki raro ki ngā taumata iti-ppm.
Mā te aroturuki i ngā huānga iti ka ārai i te tae kāore e hiahiatia me te ngoikore ā-pūkaha. Mā te kite i ngā kukū Fe, Ti, me Pb ka tautoko i te māramatanga whatu, ā, ka whakakorea ngā mōrearea mai i ngā whakaurunga, i ngā pūwāhi ahotea rānei. Mā te mahere huānga, e taea ai e te XRF-CT matatau me ngā tikanga confocal, ka manatoko i te ōritetanga o te wāhi puta noa i te pepa karaihe, i te karaihe whakarewa rānei, he mea nui mō te whakaputanga tauine nui.
Mā ngā taputapu XRF kawe me ngā taputapu XRF ā-roto e aunoa te matawai tere, e whakauru ana i ngā hua ki te whakahaere tukanga wā-tūturu. Mā tēnei huarahi ka arotauhia te kounga o te hanga karaihe, e tautoko ana i ngā whakaritenga hua tino pakari me te urupare tonu ki ngā pekapeka tukanga.
Ngā Tikanga Tautuhi me te Wehewehenga Momo
Ko ngā momo tikanga tautuhi karāhe ko te tohu matimati XRF, te ine i te mātotoru, me te aromatawai i te taupū whakaata. Mā te tohu matimati XRF ka tukuna he whakatauira huānga tika, kore-whakangaro mō ngā huānga matua katoa o te hanganga karāhe, ka taea ai te kite i te Si, Na, Ca, Mg, Al, Pb, me te K me te āheinga whakahoki i raro i te 3% RSD. Mā ngā ine mātotoru ka āwhina i te wehewehe i te hanganga o ngā rauemi karāhe me ngā rerekētanga mai i te 2.2 g/cm³ (houra-raima) ki runga ake i te 3.1 g/cm³ (karāhe mata). Mā te aromatawai i te taupū whakaata ka wehe tika i te houra-raima, te borosilicate, me te karāhe mata; ko ngā uara nD noa kei waenga i te 1.51 ki te 1.70.
Ka whakarei ake te tātari tatauranga i te tika o te tautuhi. Ka whakarōpūhia e te whakarōpū K-means ngā kongakonga karāhe mā roto i ngā huinga raraunga XRF maha-huānga, e tautoko ana i ngā reiti ōrite akomanga taihara neke atu i te 95%. Ka wehea e te tātari hononga hina ngā nekehanga hanganga iti engari motuhake i waenga i ngā puranga, i ngā momo rerekētanga rānei. Ka whakarōpūhia e ngā tauira matū ngā āhua karāhe (hei tauira, ngā pirepire karāhe hanumi me te karāhe paura) mā te tapumati huānga me te tika neke atu i te 98% ina whakauruhia ki ngā raraunga XRF.
Te Whakapūmau Kounga mō te Hanga Karāhe
Ko te whakapūmautanga kounga o te hanga karāhe e whakawhirinaki ana ki te tere me te tika o te kimi i ngā huānga maha. Ka manatokohia e ngā tātaritanga XRF ā-roto me ngā tātaritanga taiwhanga te hanganga o ngā rauemi karāhe i roto i ngā hēkona. Ka tautuhia e te fluorescence hihi-X te SiO₂, Na₂O, CaO, MgO, Al₂O₃, PbO, me te K₂O, e tautoko ana i te whakahaere i ngā huānga o te hanganga karāhe me te ōritetanga o te puranga.
E ai ki ngā raraunga ahumahi, ka taea e te XRF te whakatutuki i ngā herenga kitenga ki raro ki te 1 ppm mō ngā huānga iti, ka taea ai te kimi i ngā poke iti e pā ana ki ngā āhuatanga, ki te ataahua rānei. Mā te whakatinanatanga o te XRF ka taea te urupare tika mō ngā whakatikatika tukanga, ka piki ake te hua tae atu ki te 15% i roto i ngā raina e tino whakahaeretia ana.
Ka honoa te whakarōpūtanga aunoa ki te mahi whakaputa, kia mau tonu ai te manatoko i te hanganga o ngā rauemi karāhe. Mā tēnei ka whakaitihia te rerekētanga o ia puranga, ā, ka whakakorea hoki ngā hua kāore i te tino tika. He mea nui te tirotiro i ngā huānga maha mō te QA o ngā kounga o ngā pirepire karāhe kua whakakotahihia, ngā whakamahinga o ngā pirepire karāhe, me ngā whakamahinga paura karāhe. Mā ngā tirotiro whānui i te papaanga ka whakaitihia te wā kore mahi, ā, ka taea te whakatikatika tonu, ka tautoko i te kounga hua pumau.
