Ngaba uyazi ngeengqekembe zesikhumbuzo zesinyithi esixabisekileyo?
Indlela yokwahlula iintsimbi ezixabisekileyo
Kwiminyaka yakutshanje, imakethi yokurhweba ngeengqekembe zesinyithi esixabisekileyo iye yachuma, kwaye abaqokeleli banokuthenga kwiindlela eziphambili ezifana namaziko okuthengisa ngqo ngeengqekembe zaseTshayina, amaziko emali, kunye nabathengisi abaneelayisenisi, kunye nokurhweba kwiimarike zesibini. Ngokuchasene neemeko zentengiselwano ezikhulayo, iingqekembe zesinyithi esixabisekileyo ezingeyonyani neziphantsi nazo ziye zenzeka ngamanye amaxesha. Kubaqokeleli abaye bachaphazeleka kancinci kwiingqekembe zesinyithi esixabisekileyo, bahlala benamathandabuzo malunga nokunyaniseka kweengqekembe zesikhumbuzo ezithengwe ngaphandle kweendlela ezisemthethweni ngenxa yokunqongophala kwezixhobo zovavanyo zobungcali kunye nolwazi lweendlela zokusebenzisa iingqekembe.
Ukuphendula kwezi meko, namhlanje siza kwazisa ezinye iindlela nolwazi olusisiseko olusetyenziswa luluntu ukwahlula ubunyani beengqekembe zesikhumbuzo zesinyithi esixabisekileyo.

Imeko esemthethweni: Ezinye iingqekembe zesikhumbuzo zesinyithi esixabisekileyo zinokuba nemeko esemthethweni kwaye zingasetyenziswa njengexabiso elisemthethweni kumazwe athile, kodwa zihlala zithathwa njengezinto eziqokelelweyo okanye iimveliso zotyalo-mali.
Iinkcukacha kunye nokuchongwa kwezinto ezixabisekileyo zeengqekembe zesikhumbuzo zesinyithi esixabisekileyo
Ukuchongwa kweenkcukacha zemveliso kunye nezixhobo kukwasisixhobo esibalulekileyo kuluntu ukwahlula ubunyani beengqekembe zesikhumbuzo zesinyithi esixabisekileyo.

Umbuzo weNethiwekhi yeGolide yeTshayina

Ngaphandle kwePanda Precious Metal Memorial Coin, ezinye iingqekembe zesikhumbuzo zesinyithi esixabisekileyo ezikhutshwe kwiminyaka yakutshanje ngokubanzi azisaphawulwanga ngobunzima kunye nemeko kumphezulu weengqekembe. Abaqokeleli banokusebenzisa indlela yokuqaphela imifanekiso ukukhangela ulwazi malunga nobunzima, imeko, iinkcukacha, kunye nolunye ulwazi lweengqekembe zesikhumbuzo zesinyithi esixabisekileyo kwiprojekthi nganye ngeChina Gold Coin Network.

Nika iarhente yovavanyo yomntu wesithathu efanelekileyo

Kwiminyaka yakutshanje, iingqekembe zesikhumbuzo zesinyithi esixabisekileyo ezikhutshwe eTshayina zenziwe ngegolide ecocekileyo eyi-99.9%, isilivere, kunye neplatinum. Ngaphandle kwenani elincinci leengqekembe zobuxoki ezisebenzisa igolide ecocekileyo eyi-99.9%, uninzi lweengqekembe zobuxoki zenziwe nge-alloy yobhedu (igolide engaphezulu/isilivere ebekwe phezu kwayo). Ukuhlolwa kombala okungenakutshabalalisa kweengqekembe zesikhumbuzo zesinyithi esixabisekileyo ngokuqhelekileyo kusebenzisa i-X-ray fluorescence spectrometer (XRF), enokwenza uhlalutyo olungenakutshabalalisa lweempawu/ubungakanani bezinto zesinyithi. Xa abaqokeleli beqinisekisa ubunono, kufuneka baqaphele ukuba yi-XRF kuphela exhotyiswe ngeenkqubo zohlalutyo lwesinyithi esixabisekileyo enokuchonga ubunono begolide nesilivere. Ukusetyenziswa kwezinye iinkqubo zohlalutyo ukufumanisa izinyithi ezixabisekileyo kunokuchonga kuphela ngokweempawu, kwaye iziphumo zokufumanisa ezibonisiweyo zinokuhluka kumbala wokwenyani.Kucetyiswa ukuba abaqokeleli banike amaziko ovavanyo afanelekileyo (asebenzisa umgangatho we-GB/T18043 wokuvavanya) ukuvavanya umgangatho.

Ukuzihlola ngokwakho idatha yobunzima kunye nobungakanani

Ubunzima kunye nobukhulu beengqekembe zesikhumbuzo zesinyithi esixabisekileyo ezikhutshwa kwilizwe lethu ziveliswa ngokwemigangatho. Kukho ukuphambuka okuhle nokubi kubunzima nobukhulu, kwaye abaqokeleli abanemiqathango banokusebenzisa izikali ze-elektroniki kunye nee-calipers ukuvavanya iiparameter ezifanelekileyo. Ukuphambuka okuhle nokubi kunokubhekisa kwimigangatho yeengqekembe zegolide nezesilivere kushishino lwezemali eTshayina, olukwachaza iiparameter ezifana nenani lamazinyo entambo kwiingqekembe zesikhumbuzo zeenkcukacha ezahlukeneyo. Ngenxa yexesha lokusetyenziswa kunye nokuhlaziywa kwemigangatho yeengqekembe zegolide nezesilivere, uluhlu lokuphambuka kunye nenani lamazinyo entambo adweliswe kwimigangatho alusebenzi kuzo zonke iingqekembe zesikhumbuzo zesinyithi esixabisekileyo, ingakumbi iingqekembe zesikhumbuzo ezikhutshwe kwangoko.
Ukuchongwa kwenkqubo yeengqekembe zesikhumbuzo zesinyithi esixabisekileyo
Inkqubo yokuqokelela iingqekembe zeengqekembe zesinyithi esixabisekileyo ibandakanya ukutshiza isanti/ukutshiza ngeentsimbi, umphezulu wesibuko, imizobo engabonakaliyo kunye nombhalo, imizobo emincinci kunye nombhalo, ukuprinta kokudlulisa umbala/ukupeyinta isitshizi, njl. Okwangoku, iingqekembe zesinyithi esixabisekileyo zihlala zikhutshwa ngeenkqubo zokugqiba isanti kunye nokugqiba isibuko. Inkqubo yokutshiza isanti/ukutshiza ngeentsimbi kukusebenzisa ubungakanani obahlukeneyo beenxalenye zesanti (okanye iintsimbi, kusetyenziswa nee-laser) ukutshiza imizobo ekhethiweyo okanye iindawo zesikhunta kumphezulu onomkhenkce, okwenza isiphumo sesanti kunye ne-matte kumphezulu wengqekembe yesikhumbuzo eprintiweyo. Inkqubo yesibuko ifezekiswa ngokupolisha umphezulu womfanekiso wesikhunta kunye nekhekhe ukuze kudale isiphumo esikhazimlayo kumphezulu wengqekembe yesikhumbuzo eprintiweyo.

Kungcono ukuthelekisa ingqekembe yokwenyani nemveliso eza kuchongwa, kwaye wenze uthelekiso oluneenkcukacha kwiinkqubo ezahlukeneyo. Iipateni zokukhulula ezingasemva kweengqekembe zesinyithi esixabisekileyo ziyahluka ngokuxhomekeke kumxholo weprojekthi, okwenza kube nzima ukwahlula ubunyani ngokusebenzisa ukukhulula okungasemva ngaphandle kweengqekembe zokwenyani ezifanelekileyo okanye iifoto ezicacileyo. Xa iimeko zokuthelekisa zingafezekiswanga, kufuneka kunikwe ingqalelo ekhethekileyo kwiziphumo zokukhulula, ukuqhumisa isanti, kunye neziphumo zokucubungula isipili zeemveliso eziza kuchongwa. Kwiminyaka yakutshanje, uninzi lweengqekembe zegolide nezesilivere ezikhutshiweyo zineepateni zokukhulula eziqinileyo kwicala elingaphandle leTempile yeZulu okanye uphawu lwesizwe. Abaqokeleli banokuphepha umngcipheko wokuthenga iingqekembe zomgunyathi ngokukhangela nokukhumbula iimpawu zale pateni yesiqhelo.

Kwiminyaka yakutshanje, ezinye iingqekembe zomgunyathi zifunyenwe zinemifuziselo yangaphambili esondele kwiingqekembe zokwenyani, kodwa ukuba zichongiwe ngononophelo, ubuchule bazo busahluke kakhulu kwiingqekembe zokwenyani. Ukuqhushumba kwesanti kumphezulu wengqekembe yokwenyani kubonisa isiphumo esifanayo, esithambileyo, nesinomgangatho. Ezinye iingcango zesanti nge-laser zinokubonwa kwimo yegridi emva kokwandiswa, ngelixa isiphumo sokuqhushumba kwesanti kwiingqekembe zomgunyathi sirhabaxa. Ukongeza, umphezulu wesipili seengqekembe zokwenyani uthe tyaba kwaye ubonakalisa njengesipili, ngelixa umphezulu wesipili seengqekembe zomgunyathi uhlala unemingxuma kunye namaqhuma.
