Ingabe uyazi ngezinhlamvu zemali eziyisikhumbuzo zensimbi eyigugu?

Ingabe uyazi ngezinhlamvu zemali eziyisikhumbuzo zensimbi eyigugu?
Indlela yokuhlukanisa izinsimbi eziyigugu
Eminyakeni yamuva nje, imakethe yokuhweba ngohlamvu lwensimbi oluyigugu eyisikhumbuzo iye yachuma, futhi abaqoqi bangathenga eziteshini eziyinhloko ezifana nezikhungo zokuthengisa ngokuqondile zohlamvu lwemali lwase-China, izikhungo zezimali, nabathengisi abanamalayisense, kanye nokuhweba ezimakethe zesibili. Ngokumelene nesizinda semisebenzi echumayo, izinhlamvu zemali zesikhumbuzo zensimbi mbumbulu kanye nenani eliphansi nazo zenzeka ngezikhathi ezithile. Kwabaqoqi ababenokuchayeka okulinganiselwe ezinhlamvwini zesikhumbuzo zensimbi eyigugu, bavame ukuba nokungabaza ngobuqiniso bezinhlamvu zemali eziyisikhumbuzo ezithengwe ngaphandle kweziteshi ezisemthethweni ngenxa yokuntuleka kwemishini yokuhlola yobungcweti nolwazi lwamasu ohlamvu lwemali.
Ukuphendula lezi zimo, namuhla sizokwethula amasu athile nolwazi oluyisisekelo olusebenza emphakathini ukuze sihlukanise ubuqiniso bezinhlamvu zemali zesikhumbuzo zensimbi eyigugu.
Izici eziyisisekelo zezinhlamvu zemali eziyisikhumbuzo zensimbi eyigugu
01
Impahla: Izinhlamvu zemali zesikhumbuzo zensimbi eyigugu ngokuvamile zenziwa ngezinsimbi ezinenani eliphakeme njengegolide, isiliva, iplatinum, noma i-palladium. Lezi zinsimbi zinikeza izinhlamvu zemali eziyisikhumbuzo ngenani eliyigugu nokubukeka okuyingqayizivele.
02
Idizayini: Idizayini yezinhlamvu zemali eyisikhumbuzo ivame ukuba yinhle futhi icophelela, kufaka phakathi amaphethini ahlukahlukene, imibhalo, nemihlobiso ukuze kukhunjulwe imicimbi ethile, abalingisi, noma amatimu. Idizayini ingase ihlanganise imicimbi yomlando, izimpawu zamasiko, ama-avatar osaziwayo, njll.
03
Udaba Olunomkhawulo: Izinhlamvu zemali eziningi zensimbi eziyigugu zesikhumbuzo zikhishwa ngenani elilinganiselwe, okusho ukuthi inani lohlamvu lwemali ngalunye lilinganiselwe, okwandisa inani lalo eliqoqwayo kanye nokushoda.
04
Isisindo Nokuhlanzeka: Izinhlamvu zemali zesikhumbuzo zensimbi eyigugu ngokuvamile zimakwa ngesisindo kanye nobumsulwa bazo ukuze kuqinisekiswe ukuthi abatshalizimali nabaqoqi baqonda inani langempela nekhwalithi yabo.
05
Inani lokuqoqwa: Ngenxa yokuhluka kwayo, inani elilinganiselwe, nezinto eziyigugu, izinhlamvu zemali zesikhumbuzo zensimbi eyigugu ngokuvamile zinenani eliphezulu lokuqoqwa futhi zingase zikhuphuke inani ngokuhamba kwesikhathi.
06
Isimo esisemthethweni: Ezinye izinhlamvu zemali zesikhumbuzo zensimbi eyigugu zingase zibe nezimo ezingokomthetho futhi zingasetshenziswa njengethenda esemthethweni emazweni athile, kodwa ngokuvamile zibhekwa njengeziqoqwayo noma imikhiqizo yokutshalwa kwezimali.
Ukucaciswa Nokuhlonza Okubalulekile Kwezinhlamvu Zensimbi Eziyigugu Zesikhumbuzo
Ukuhlonzwa kokucaciswa komkhiqizo nezinto zokwakha nakho kuyithuluzi elibalulekile lomphakathi lokuhlukanisa ubuqiniso bezinhlamvu zemali zesikhumbuzo zensimbi eyigugu.

Umbuzo we-China Gold Coin Network

Ngaphandle kwePanda Precious Metal Commemorative Coin, ezinye izinhlamvu zemali zesikhumbuzo zensimbi eziyigugu ezikhishwe eminyakeni yamuva ngokuvamile azisaphawulwa ngesisindo nesimo endaweni yemali. Abaqoqi bangasebenzisa indlela yokubonwa okuyingcaca ukuze bafune ulwazi ngesisindo, isimo, imininingwane, kanye nolunye ulwazi lwezinhlamvu zemali zesikhumbuzo zensimbi eyigugu zephrojekthi ngayinye nge-China Gold Coin Network.

Nikeza i-ejensi yokuhlola yenkampani yangaphandle efanelekayo

Eminyakeni yamuva nje, izinhlamvu zemali zesikhumbuzo zensimbi eziyigugu ezikhishwe eShayina zonke zenziwe ngegolide elimsulwa elingu-99.9%, isiliva neplatinamu. Ngaphandle kwenani elincane lezinhlamvu zemali-mbumbulu ezisebenzisa u-99.9% wegolide elimsulwa nesiliva, izinhlamvu zemali zomgunyathi eziningi zenziwe nge-alloy yethusi (igolide elingaphezulu/isiliva elicwebezelayo). Ukuhlolwa kombala okungabhubhisi kwezinhlamvu zensimbi eziyigugu zesikhumbuzo ngokuvamile kusebenzisa i-X-ray fluorescence spectrometer (XRF), engenza ukuhlaziya okungabhubhisi kwekhwalithi/ubuningi bezinto zensimbi. Lapho abaqoqi beqinisekisa ukucoleka, kufanele baqaphele ukuthi yi-XRF kuphela efakwe izinhlelo zokuhlaziya insimbi eyigugu engathola ngobuningi ukucoleka kwegolide nesiliva. Ukusetshenziswa kwezinye izinhlelo zokuhlaziya ukuze kutholwe izinsimbi eziyigugu kunganquma ngekhwalithi kuphela okokusebenza, futhi imiphumela yokutholwa ebonisiwe ingase ihluke kumbala wangempela.Kunconywa ukuthi abaqoqi baphathise izikhungo zokuhlola zezinkampani zangaphandle (ezisebenzisa indinganiso ye-GB/T18043 yokuhlola) ukuhlola ikhwalithi.

Ukuzihlola ngokwakho isisindo nosayizi wedatha

Isisindo nobukhulu bezinhlamvu zensimbi eziyigugu zesikhumbuzo ezikhishwe ezweni lethu zikhiqizwa ngokuvumelana nezindinganiso. Kukhona ukuchezuka okuhle nokubi ngesisindo nosayizi, futhi abaqoqi abanemibandela bangasebenzisa izikali ze-elekthronikhi nama-caliper ukuhlola imingcele efanele. Ukuchezuka okuhle nokubi kungabhekisela emazingeni ohlamvu lwegolide nesiliva embonini yezezimali e-China, ephinde icacise imingcele efana nenani lamazinyo entambo yezinhlamvu zemali eziyisikhumbuzo zokucaciswa okuhlukile. Ngenxa yesikhathi sokusetshenziswa nokubuyekezwa kwamazinga ohlamvu lwegolide nesiliva, ububanzi bokuchezuka kanye nenani lamazinyo entambo asohlwini lwezindinganiso azisebenzi kuzo zonke izinhlamvu zemali zesikhumbuzo zensimbi eyigugu, ikakhulukazi izinhlamvu zemali zesikhumbuzo ezikhishwe ngaphambi kwesikhathi.
Ukuhlonza inqubo yezinhlamvu zemali zesikhumbuzo zensimbi eyigugu
Inqubo yohlamvu lwemali lwezinhlamvu zemali zesikhumbuzo zensimbi eyigugu ikakhulukazi ihlanganisa ukuqhunyiswa kwesihlabathi/ukufafazwa kobuhlalu, indawo yesibuko, ihluzo ezingabonakali nombhalo, izithombe ezincane nombhalo, ukuphrinta ukudluliswa kombala/ukupenda kokufutha, njll. Njengamanje, izinhlamvu zemali zesikhumbuzo zensimbi eziyigugu zivame ukukhishwa ngazo zombili i-sandblasting kanye izinqubo zokuqeda isibuko. Inqubo yokufafaza i-sandblasting/bead iwukusebenzisa amanani ahlukene ezinhlayiya zesihlabathi (noma ubuhlalu, futhi kusetshenziswa ama-lasers) ukufafaza imidwebo ekhethiwe noma izindawo zesikhunta endaweni eneqhwa, kwakheka umphumela oyisihlabathi kanye ne-matte ebusweni besikhumbuzo esiphrintiwe. uhlamvu lwemali. Inqubo yesibuko ifinyelelwa ngokupholisha ubuso besithombe sesikhunta kanye nekhekhe ukudala umphumela ocwebezelayo ebusweni bohlamvu lwemali lwesikhumbuzo oluphrintiwe.

Kungcono ukuqhathanisa uhlamvu lwemali lwangempela nomkhiqizo ozokhonjwa, futhi wenze ukuqhathanisa okuningiliziwe kusuka ezinqubweni ezihlukahlukene. Amaphethini okusiza angemuva kwezinhlamvu zensimbi eziyigugu zesikhumbuzo ayahluka kuye ngetimu yephrojekthi, okwenza kube nzima ukuhlukanisa ubuqiniso ngokukhululeka okungemuva ngaphandle kwezinhlamvu zemali zangempela ezihambisanayo noma izithombe ezinencazelo ephezulu. Lapho izimo zokuqhathanisa zingafinyelelwanga, ukunakwa okukhethekile kufanele kukhokhwe ekusizeni, ekuqhumeni kwesihlabathi, kanye nemiphumela yokucubungula isibuko yemikhiqizo ezokhonjwa. Eminyakeni yakamuva, iningi lezinhlamvu zemali zegolide nezesiliva ezikhishiwe zinamaphethini osizo angashintshile endaweni ephambene yeThempeli laseZulwini noma uphawu lwesizwe. Abaqoqi bangagwema ingozi yokuthenga izinhlamvu zemali zomgunyathi ngokusesha nokubamba ngekhanda izici zale phethini evamile.

Eminyakeni yamuva nje, ezinye izinhlamvu zemali zomgunyathi zitholakale zinamaphethini okusiza angaphambili aseduze nezinhlamvu zemali zangempela, kodwa uma zihlonzwa ngokucophelela, ubuciko bazo zisahluke kakhulu emalini yangempela. I-sandblasting endaweni yemali yangempela iveza umphumela ofanayo kakhulu, othambile, futhi onezingqimba. Okunye ukuqhuma kwe-laser sandblasting kungabonwa kusimo segridi ngemva kokukhuliswa, kuyilapho umthelela we-sandblasting ezinhlamvu zemali zomgunyathi mubi. Ngaphezu kwalokho, indawo yesibuko yezinhlamvu zemali zangempela isicaba futhi ibukeka njengesibuko, kuyilapho indawo yesibuko yezinhlamvu zemali-mbumbulu ivame ukuba nemigodi namaqhubu.
