Ubumsulwa besiliva buchaza iphesenti lesiliva eliyisisekelo (i-Ag) elikhona kusampula yensimbi. Isiliva elihle—eliphawulwe ngokuthi .999—liqukethe isiliva elihlanzekile elingu-99.9%, okwenza lifaneleke kuma-bullion bar kanye nezinhlamvu zemali ezikhethiwe. Isiliva elicwebezelayo lakhiwe ngesiliva elingu-92.5% elihlanganiswe nethusi elingu-7.5% noma ezinye izinsimbi ukuze kuqiniswe imishini; imboni iphawula izinto ezinjalo ngokuthi “925.” Amabanga aphansi, njengesiliva elingu-60%, afaka ithusi elingu-40%, i-nickel, noma i-zinc. Lezi zinsimbi zibusa izinto ezingezona ubucwebe kanye nezinsalela zenani eliphansi, lapho ukuqina kwemishini kudlula izidingo zobuhle. Izindinganiso zokwakheka kwesiliva ziyahlukahluka: isiliva laseBritannia (95.8%), isiliva lemali (~90%), kanye nezinye izinhlobo ezenziwe ngokwezifiso ezenzelwe izinjongo zezimboni noma zokuhlobisa.

Izinselele Zokulinganisa Amazinga Okuhlanzeka Kwesiliva Aphansi
Ukuhlolwa kobumsulwa besiliva bendabuko—ukuhlolwa kwe-asidi kanye nokuhlolwa komlilo—kunzima ngokuhlanganiswa okuphansi nokuxubile. Ukuhlolwa kwe-asidi kunikeza ukufundwa kobuso kuphela futhi kwehluleka ukulinganisa ubumsulwa obungaphansi kwamazinga aqinile. Ubunzima be-alloy, njengoba kubonakala kusiliva esingu-60%, kubangela izinkomba zombala ezingathembekile futhi kudinga ukusampula okubhubhisayo kokuhlolwa komlilo. Ukuhlolwa kokwakheka kwesiliva okunembile, okungabhubhisi kudinga izixazululo zedivayisi yokuhlola isiliva ye-XRF.
Ubuchwepheshe Bokuhlola Isiliva be-XRF: Indlela Okusebenza Ngayo
Izimiso Zokuhlaziywa kwe-XRF Yesiliva
I-X-ray fluorescence (XRF) ihlasela isampula yesiliva eqinile ene-X-ray enamandla aphezulu, ikhipha ama-electron angaphakathi kwegobolondo futhi ibangele ukukhishwa kwe-X-rays ekhanyayo ethize yesakhi.insimbi eyiguguIsihlaziyi sibamba futhi silinganise lokhu kukhishwa; inani lamandla ngalinye elitholiwe lihambelana ngqo nesakhi esihlukile—isiliva, ithusi, i-nickel, noma i-zinc. Ukuqina kwenani kuhambisana nokuhlushwa kwesakhi, okuvumela ukuhlolwa kokwakheka kwesiliva okunembile kuzo zonke izinhlobo zokungcola okuphezulu nokuphansi.
Isicelo se-LONN-T890 ekuhlolweni kwe-Silver Plate kanye ne-Alloy
I-LONN-T890 inikeza ukuhlolwa okunembile, okungabhubhisi ubumsulwa besiliva kwezinto ezifakwe ipulasitiki kanye nama-alloy axubile.

Abasebenzisi bezimboni, izindawo zokuhlanza, kanye nabasebenzisa kabusha basebenzisa ukuphindaphindwa okuphezulu komhlaziyi ukuvimbela ukuhlolwa okungaphelele kwezinto ezifakwe ipulasitiki noma izinto ezihlanganisiwe. Izindlu zokuthengisa zithembele kudivayisi yokuhlola isiliva ye-Lonnmeter XRF ukuqinisekisa amanani amenyezelwe kanye nokuguqulwa kwamabala ezingcezu eziqoqwayo.
Izinto Okufanele Uzicabangele Ngokunembile Nokulinganisa
Ukulungiswa okuzenzakalelayo kulungisa ukuzulazula kwemvelo kanye nezinsimbi, kuqinisekisa ukufundwa okunembile kokuqukethwe kwesiliva. Ama-algorithms akhokhela izinto ezivamile zokuhlanganisa njengethusi ne-nickel, okunciphisa ukuphazamiseka ekubalweni kwamaphesenti. I-analyzer ikhomba ukwakheka kwesisekelo sensimbi, okubalulekile ekuhlukaniseni okuqinile ezintweni ezifakwe ipulasitiki. Imiphumela iboniswa njenge-spectra yezinto eziyisisekelo kanye namayunithi okuhlanzeka okwenziwe ngokwezifiso, kunciphisa iphutha lomqhubi futhi kusekela ukuhambisana okugcwele ekuhlaziyweni kwesiliva kwe-XRF kanye nemibhalo yokulawula.
Ukuqinisekiswa Kokuhlanzeka Kwesiliva: Kusukela Kubucwebe Kuya Kuzicelo Zezimboni
Ukuqinisekiswa kweHallmark kanye nokuhambisana nomthetho
Amadivayisi okuhlola isiliva e-XRF afana ne-Lonnmeter LONN-T890 avumela ukuqinisekiswa kwenani lamazinga okuhlanzeka kwesiliva okugxiviziwe (isb., 925, .999, noma .800) ngemizuzwana. Ukuhlaziywa esikalini se-micron kukhomba izinto ezingahlanzekile kungakhathaliseki ukuthi zigxiviziwe kahle, okuveza ukwakheka kwesiliva okungafanele noma ukungalandeli izindinganiso zomthetho. I-LONN-T890 ihlola ukufaneleka kwezimpawu zesiliva ngokumelene nemigomo yemboni, iqinisekisa ukuthi insimbi engaphezulu ihambisana nokubekezelelana kobucwebe okusemthethweni. Ezintweni zakudala noma imigoqo yesiliva kaJohnson Matthey, ukuhlaziywa kwe-XRF kuqinisekisa ubuqiniso ngokufanisa ngqo isiginesha se-spectral nezindinganiso ezaziwayo, ukwembula ama-formeries noma i-plating engabhaliwe.
Ukuhlaziywa kwe-XRF ekuHlanzeni nasekuTholeni
Izikhungo zokuhlanza zisebenzisa ukuhlolwa kwesiliva okungabhubhisi nge-XRF ukuze kuhlungwe ngokushesha izinto, kuqinisekiswa ubumsulwa besiliva ezingcoleni, ubucwebe, kanye nezingxenye zezimboni. Umshini wokuhlola isiliva we-Lonnmeter LONN-T890 XRF wobucwebe ubona okuqukethwe kwesiliva kuze kufike ku-60% ubumsulwa futhi uchaza ngokunembile ukungcola kwensimbi okuyisisekelo. Idatha yokwakheka kwendawo iveza ukungalingani kokwakheka kanye nezinto ezilandelekayo, isekela ukuhlolwa kwemvelaphi kanye nokutholakala kwemithombo yensimbi exubile noma engcolile. Le ndlela yokulinganisa iqinisa ukuhambisana nemithetho yokuthola kanye nokulandelela emigqeni yokuhlinzeka ngesiliva.
Indima ye-XRF Emakethe Yesiliva Yanamuhla
Ukuhlangabezana Nezidingo Zemboni Nezokuqoqa
Amadivayisi okuhlola isiliva e-XRF manje aseyizindinganiso zobucwebe kanye nokuqinisekiswa kwe-bullion. Imiphumela esheshayo, engonakalisi ivumela abathengi nabathengisi ukuqinisekisa ubumsulwa bepuleti lesiliva, imigoqo, izinhlamvu zemali, kanye nokuhlanganiswa okuxubile ngaphandle kokususwa kwesampula noma umonakalo ongenakulungiseka. I-Lonnmeter LONN-T890 iletha imibiko yedijithali elinganiselwe, ukusekela ukuhlolwa kanye nokuthunyelwa kwemithetho, ukuhlangabezana nezimfuno zemboni zokucaca kuzo zonke izimakethe zokuthola, ukuthengisa kabusha, kanye nabaqoqi. Lawa madivayisi akhulisa ukwethembana futhi asiza ukuvimbela ukukhwabanisa ngokwembula izinto zesiliva ezingahlanzekile noma zomgunyathi, isidingo esibalulekile njengoba intshisekelo yabaqoqi esilivani lakudala nelingahlanzekile kangako ikhuphuka.
Ukuqhathanisa i-XRF Nezinye Izindlela Zokuhlola
Ukuhlolwa kwe-asidi yendabuko kulimaza izindawo, kudinga ukuvezwa kwesampula, futhi kuveza imiphumela elinganiselwe kuphela yamazinga okuhlanzeka kwesiliva, ngokuvamile kungabi nama-alloy ahlanganisiwe kanye ne-plating yesiliva. Ukuhlaziywa kwe-XRF yokuhlolwa kwesiliva, ngokuphambene nalokho, kuhlinzeka ngokuhlolwa kokwakheka kwesiliva okuthile ngokunemba okulinganiselwe kusukela ebusweni kuya ku-substrate. Ukuhlaziywa kwe-XRF okungabhubhisi kuthola okuqukethwe kwesiliva okufika ku-60% ngemizuzwana, kwembula izakhiwo ezinezingqimba kanye nokuhlanganiswa kwensimbi okuyisisekelo okungatholakali ngezindlela zamakhemikhali. Ukufakwa kwedatha yedijithali kuvumela ukuqinisekiswa kwezimpawu ngokuzenzakalela kanye nokugcinwa kwemibhalo, kuyilapho ukuhlolwa kwe-asidi kunganikezi amarekhodi ahlala njalo.
Kungani Ucela Isilinganiso se-LONN-T890?
Isilinganiso esenzelwe wena se-Lonnmeter T890 siqinisekisa ukuthi idivayisi yokuhlola isiliva ye-XRF ekhethiwe ihambisana nezinhlelo zakho zokusebenza—izimpahla ezifakwe amapulangwe, izingcezu, imigoqo, noma ama-alloy ayinkimbinkimbi. I-Lonnmeter inikeza ukubonisana ngobuchwepheshe, ukuhlolwa kwesampula okubukhoma, amaphakheji esofthiwe aqondene nohlelo lokusebenza, kanye nensizakalo eqhubekayo. Ukusekelwa okuphelele kufaka phakathi ukuqeqeshwa endaweni, ukulinganisa, kanye nezibuyekezo. Lokhu kwenza ochwepheshe bezitolo, abahluzi, noma abaphinda basebenzise ukuhlolwa kwesiliva okungonakalisi nge-XRF ukuze kulandelwe imithetho kanye nokusebenza kahle.
