Ukulawulwa okunembile kokwakheka kwesimende kuqinisekisa amandla adingekayo, ukuqina, kanye nokuhambisana nemithetho. Ngisho nokuphambuka okuncane kokuqukethwe kwezinto eziyisisekelo—njenge-CaO, i-SiO₂, i-Al₂O₃, i-Fe₂O₃, i-MgO, kanye ne-SO₃—kuthinta ngqo ukusebenza komshini kanye nokuziphatha kwesikhathi eside. Isibonelo, i-CaO kumele ihlale ngaphakathi kuka-60–67%, kuyilapho i-MgO kanye ne-SO₃ ngokuvamile kumele ihlale ngaphansi kuka-5% no-3%, ngokulandelana, njengoba kuchazwe yi-ASTM C150. Ukuguquguquka kwe-chemistry kuyingozi yokungasebenzi kahle, izikhathi zokusetha ezishintshiwe, ukulahlekelwa amandla, noma ukwehluleka kokuqina. Izindlela ezingonakalisi, ezinobungako njengokuhlaziywa kwesimende se-xrf zivumela ukulungiswa okusheshayo, ukuvimbela ukwenqatshwa kweqembu elikhulu noma ukubuyiselwa okubizayo.

Ukuhlaziywa kwe-XRF ye-Cement Engabhubhisi
Ukuhlaziywa kwesamente ye-XRF kunikeza ukulinganiswa okungabhubhisi kwe-CaO, i-SiO₂, i-Al₂O₃, i-Fe₂O₃, kanye ne-MgO ezintweni zokusetshenziswa, ama-clinker, kanye nama-batch aqediwe. Abahlaziyi be-XRF, kokubili benchtop kanye ne-handheld, bacubungula amasampula amaningi ngehora. Izifundo zokubhekisela eziqinisekisiwe ziqinisekisa ukuphindaphindwa, ngokunemba okungaphansi kwe-0.5% RSD yama-oxide amakhulu. Ukulungiswa kwesampula njengempuphu ecindezelwe noma ubuhlalu beglasi obuhlanganisiwe kuqinisekisa ukunemba; ama-pellet avumela ukuhlolwa okusheshayo, ubuhlalu buveza iqiniso eliphakeme lokulawula ikhwalithi. Ukuhlaziywa kwesamente ye-XRF kusekela ukwakheka okuhambisanayo. Idatha evela ekuhlaziyweni kwe-XRF iqondisa ukulungiswa kwe-feedstock futhi iqinisekisa ukuthi isamente esiqediwe ihambisana nezindinganiso ezidingekayo. Ukumbozwa okuphelele kwezinto—ama-oxide amakhulu namancane—kuvumela ukuhlolwa okusheshayo kokuthobela imithetho kanye nokuqinisekiswa kwe-batch. Ngokusetshenziswa okuncane kakhulu futhi kungekho ukubhujiswa kwesampula, ukuhlolwa kwesamente ye-XRF kunciphisa izindleko zokusebenza ngenkathi kuvumela ukuhlolwa kabusha okusheshayo kanye nokwenza ngcono inqubo.
Intuthuko Ekuhlaziyweni Kokwakheka Kwesimende Kusetshenziswa i-XRF
Ukuhlaziywa kwesamente ye-XRF kuhlukanisa izinhlobo zesimende ngeminwe yamakhemikhali ehlukile, kuthwebula amaphrofayili aqondile e-elemental e-SiO₂, i-CaO, i-Al₂O₃, i-Fe₂O₃, kanye ne-MgO. Ucwaningo lubonisa amanani e-R² angaphezu kuka-0.97 okulinganisa izinto ezinkulu nezincane, okuvumela ukuhambisana ngokuqinile nezindinganiso ze-ASTM C150-12. Ukuhlaziywa kwesamente ye-XRF kuthola amasignesha ezinto ezincane ukuze kuhlukaniswe izinhlobo, imithombo, noma ngisho nokwehluka kwezinga le-batch. Idatha ye-XRF yobuningi isekela ukulungiswa kwengxube eluhlaza, yehlisa imfucuza kanye nokuthuthukisa ukuhambisana komkhiqizo we-batch-to-batch. Imiphumela ye-XRF yesamente ivumela izenzo zokulungisa ngokushesha ekuxubeni noma ekuphekeni kwe-kiln. Abasebenzi basebenzisa ukulandelela izinto eziphilayo ukuze babone ukuphambuka kwemishini noma kwe-feedstock, kuvimbele ukusebenza komkhiqizo ongekho ku-spec. I-Lonnmeter XRF spectroscopy yokuhlola isamente ihlanganisa ukuhlaziywa kokwakheka kwesamente okusheshayo, okungabhubhisi nokubika okuzenzakalelayo kokulawula izitayela. Lo msebenzi uxhumanisa kakhulu ukuhlolwa kwesamente ye-XRF kwekhwalithi, ukuhlaziywa kwe-XRF yezinto zokusetshenziswa zesimende, kanye nokuhlolwa kwesamente okungabhubhisi ne-XRF.
Indlela Yokuhlaziya Usimende Nge-XRF?
Qoqa isampula emele esigabeni senqubo efanele—ukudla okuluhlaza, i-clinker, noma usimende wokugcina. Lungisa isampula njenge-pellet ecindezelwe usebenzisa umfutho we-hydraulic; lokhu kudala indawo efanayo yokuhlaziywa kwe-XRF cement okuqhubekayo. Beka i-pellet ku-Lonnmeter XRF analyzer.
Ithuluzi leLonnmeter, elilinganiswe ngezinto zokubhekisela eziqinisekisiwe, lilinganisa ama-key cement oxides (SiO₂, CaO, Al₂O₃, Fe₂O₃, MgO) ngaphansi kwemizuzu emibili. Ukuzenzakalela kunciphisa ukungenelela ngesandla, kunciphisa ingozi yamaphutha omuntu. Isofthiwe ehlanganisiwe ikhiqiza imibiko eyisisekelo esheshayo.
Qhathanisa imiphumela namashadi okulawula izinqubo kanye nezinhloso. Yenza ukulungiswa kwenqubo ku-mix eluhlaza noma ukudla kwe-kiln njengoba kudingeka ukuze ugcine imininingwane yomkhiqizo. Gcina idatha yokuhlaziya, kufaka phakathi i-batch, i-opharetha, kanye nokulandelela ukulinganisa, ukuze usekele ukuhlolwa kanye nokuhambisana. Lokhu kuhlaziywa kokwakheka kwe-simende kusetshenziswa i-XRF kuqinisekisa ukuphindaphindwa, ukuziphendulela, kanye nokulawulwa kwekhwalithi ye-simende okuqinile.
Izinzuzo Zokuhlolwa Kwesimende Okungabhubhisi nge-XRF
Ukuhlaziywa kwesamente ye-XRF okungabhubhisi kulondoloza isampula, kususa ukulahleka ngesikhathi sokulinganisa futhi kuvumela ukuhlolwa kabusha okusheshayo. Abasebenzi bangahlola izinto zokusetshenziswa ezingenayo, amaqoqo emikhiqizo eqediwe, kanye nokhonkolo olusetshenziswe kabusha ngqo endaweni yokusetshenziswa. Ukuhlaziywa kwesamente ye-XRF kusekela izinqumo zenqubo esheshayo—imiphumela itholakala ngemizuzu embalwa emigqeni yokukhiqiza noma ezindaweni zokwakha.
Ukuhlolwa kwe-XRF kwekhwalithi yesimende kwenza kube lula ukuthola izakhi eziningi ze-Ca, Si, Al, Fe, Mg, kanye ne-trace elements ngaphandle kokugaya, ukusika, noma ukukhipha umongo. Lokhu kunciphisa kakhulu ingozi yokungcoliswa okuphambene futhi kugcina ubuqotho besampula yemizila yokuhlola. I-XRF yesimende iphinde ivumele ukuhlaziywa kabusha kwamaqoqo abalulekile, isekele ukulandelelwa kanye nokuhambisana nomthetho.
Ukuhlaziywa kwe-XRF Yezinto Zokusetshenziswa Kwesimende: Amaphuzu Okulawula Inqubo
Ukuhlaziywa kwesamente ye-XRF kwenza kube lula ukuqapha ukuguquguquka kwezinto eziyisisekelo ku-limestone, ubumba, umlotha wezimpukane, kanye nama-slag. Ukwakheka kwezinto eziluhlaza kuyashintsha nsuku zonke; i-CaO ingaguquguquka ngo-±3%, i-SiO₂ ±2%. Abahlaziyi be-Lonnmeter XRF bahlinzeka ngedatha ye-oxide eningi ngaphansi kwemizuzu emibili, okuvumela opharetha ukuthi bathole ukuphambuka futhi balungise izilinganiso zokudla ngokushesha. Leli zinga lokulawula linciphisa ukukhiqizwa okungacacisiwe kanye nezindleko zokulungisa i-clinker okungenani ngo-15%.
Ukuhlaziywa kokwakheka kukasimende kusetshenziswa i-XRF kuqinisekisa ukuhambisana nemikhawulo yokulawula ezintweni ezisindayo kanye nezakhi zokulandelela, okuhlanganisa i-Pb, i-Cr, ne-Hg, kuze kufike ku-10 ppm. Ukuhlolwa kwe-XRF ku-inthanethi kwekhwalithi yesimende kusekela imikhuba eqhubekayo ngokuqinisekisa izinto zokusetshenziswa ezisetshenzisiwe kanye nezinye ngaphandle kokuphazamiseka kwenqubo.
Abahlaziyi be-Lonnmeter XRF: Ukunika amandla ubuhle
Ama-spectrometer amancane e-Lonnmeter ahlinzeka ngokuhlaziywa kwesamente ye-XRF okusheshayo, okunezakhi eziningi zezinto zokusetshenziswa, ama-clinker, kanye nezinhlanganisela zokugcina. Imiphumela ye-CaO, i-SiO₂, i-Al₂O₃, i-Fe₂O₃, i-MgO, kanye ne-SO₃ iyatholakala ngemizuzu embalwa.
Izinhlelo zokuphatha amasampula ezizenzakalelayo zinciphisa amaphutha omqhubi, zenza imisebenzi ibe sezingeni elifanayo, futhi zikhulise ukuphindaphindeka ekuhlaziyweni kokwakheka kukasimende kusetshenziswa i-XRF. Uchungechunge ngalunye luhleleka, lunciphisa ukungenelela ngesandla futhi lusekela ukusebenza kahle kwelabhorethri. Umklamo wokuhlaziya oqinile umelana nothuli, ukudlidliza, kanye nokushintsha kwezinga lokushisa kuzo zonke izitezi zokukhiqiza, amalabhorethri, kanye nezindawo zasensimini.
I-XRF Spectroscopy Yokuhlolwa Kwesimende: Khetha i-Lonnmeter
Abahlaziyi be-Lonnmeter XRF banikeza imikhawulo yokuthola ephezulu ngokulinganisa ama-oxide kanye nezinto zokulandelela kuze kufike emazingeni e-ppm kusimende. Ukuhlanganiswa kwesofthiwe kunikeza ukubika okusheshayo, ukuhlaziywa kwezitayela, kanye nezaziso zokuphambuka zokuphathwa kwemininingwane. Cela izingcaphuno manje!
