Nzira yekusiyanisa simbi dzinokosha
Mumakore achangopfuura, musika wekutengesa wesimbi wakawedzera, uye vateresi vanogona kutenga kubva kumatanho ekutanga senge maChina emari ekutengesa zvakananga masangano, masangano ezvemari, uye vatengesi vane marezinesi, pamwe nekutengesa mumisika yechipiri. Zvichipesana nemamiriro ekutengeserana ari kuwedzera, mari dzesimbi dzemanyepo nedzepasi dzakakosha dzakaitikawo nguva nenguva. Kune vaunganidzi vanga vaine ruzivo rushoma kumari dzesimbi dzinokosha dzechirangaridzo, vanowanzove nekupokana nezveuchokwadi hwemari yekurangarira inotengwa kunze kwenzira dzepamutemo nekuda kwekushaikwa kwemichina yekuyera yehunyanzvi uye ruzivo rwemaitiro emari.
Tichipindura mamiriro ezvinhu aya, nhasi tichasuma mamwe matekiniki neruzivo rwekutanga runoshanda kune veruzhinji kuti vasiyanise huchokwadi hwemari yesimbi yakakosha yekurangarira.
Hunhu hwakakosha hwesimbi inokosha yekurangarira mari
01
Material: Mari dzesimbi dzinokosha dzechirangaridzo dzinowanzo gadzirwa nesimbi dzinokosha zvikuru segoridhe, sirivheri, platinamu, kana palladium. Idzi simbi dzinopa mari yekurangarira ine kukosha kwakakosha uye chitarisiko chakasiyana.

Yakaganhurirwa Nyaya: Masimbi akawanda anokosha ekurangarira esimbi anopihwa muhuwandu hushoma, zvinoreva kuti huwandu hwemari yega yega hushoma, zvichiwedzera kukosha kwayo kuunganidzwa uye kushomeka.
04
Huremu uye Kuchena: Mari yakakosha yesimbi yekurangarira inowanzo cherechedzwa nehuremu hwadzo uye kuchena kuti ive nechokwadi chekuti vatengesi nevateresi vanonzwisisa kukosha kwavo chaiko nemhando.
05
Kukosha kwekuunganidza: Nekuda kwekusiyana kwayo, huwandu hushoma, uye zvinhu zvakakosha, mari dzesimbi dzinokosha dzinowanzova neukoshi hwepamusoro hwekuunganidza uye dzinogona kuwedzera kukosha nekufamba kwenguva.
06
Mamiriro emutemo: Dzimwe simbi dzinokosha dzechirangaridzo dzinogona kunge dziine pamutemo uye dzinogona kushandiswa sezviri pamutemo matende mune dzimwe nyika, asi dzinowanzoonekwa sekuunganidzwa kana zvigadzirwa zvekudyara.
Tsanangudzo uye Material Identification yePrecious Metal Yekurangarira Coins
Kuzivikanwa kwezvakatemwa zvechigadzirwa uye zvekushandisa zvakare chishandiso chakakosha kune veruzhinji kuti vasiyanise huchokwadi hwemasimbi anokosha ekurangarira mari.

China Gold Coin Network Mubvunzo

Kunze kwePanda Precious Metal Commemorative Coin, mamwe masimbi anokosha ekurangarira akabudiswa mumakore achangopfuura haawanzo kucherechedzwa nehuremu uye mamiriro pamari yesimbi. Vaunganidzi vanogona kushandisa nzira yekuzivikanwa kwegraphic kutsvaga ruzivo rwehuremu, mamiriro, zvakatemwa, uye rumwe ruzivo rwemari yakakosha yesimbi yekurangarira yepurojekiti yega yega kuburikidza neChina Gold Coin Network.

Isa iyo inokwanisa yechitatu-bato rekuongorora agency

Mumakore achangopfuura, mari yakakosha yesimbi yekurangarira yakapihwa kuChina ese akagadzirwa ne99.9% goridhe rakachena, sirivheri, uye platinamu. Kunze kwenhamba shoma yemari yekunyepedzera inoshandisa 99.9% goridhe rakachena nesirivha, mari zhinji dzemanyepo dzakagadzirwa nemhangura alloy (pamusoro pegoridhe / sirivheri plating). Iyo isingaparadze ruvara yekuongorora yeakakosha simbi yekurangarira mari inowanzo shandisa X-ray fluorescence spectrometer (XRF), iyo inogona kuita isinga paradza hunhu / huwandu hwekuongorora kwezvinhu zvesimbi. Kana vaunganidzi vachisimbisa hunyoro, ivo vanofanirwa kucherechedza kuti XRF chete yakashongedzerwa neanokosha simbi yekuongorora zvirongwa ndiyo inogona kuona muhuwandu kunaka kwegoridhe nesirivha. Kushandiswa kwemamwe mapurogiramu ekuongorora kuona simbi dzinokosha kunongokwanisa kuona zvinhu, uye mhedzisiro yekuona yakaratidzwa inogona kusiyana kubva kune yechokwadi ruvara.Zvinokurudzirwa kuti vateresi vape vanokwanisa vechitatu-bato rekuongorora masangano (vachishandisa GB/T18043 yakajairwa yekuyedza) kuyedza mhando.

Kuzviongorora kwehuremu uye saizi data

Huremu uye saizi yemari yakakosha yesimbi yekurangarira yakapihwa munyika yedu inogadzirwa zvinoenderana nezviyero. Kune zvakanaka uye zvisina kunaka kutsauka kwehuremu uye saizi, uye vateresi vane mamiriro vanogona kushandisa zvikero zvemagetsi uye calipers kuyedza ma paramita akakodzera. Kutsauka kwakanaka uye kwakashata kunogona kureva zviyero zvegoridhe nesirivheri muindasitiri yezvemari muChina, iyo inotsanangurawo zvimiro zvakaita sehuwandu hwemazino eshinda emari yekurangarira yezvakasiyana zvakatemwa. Nekuda kwekuita nguva uye kudzokororwa kwegoridhe nesirivheri zviyero, kutsauka uye nhamba yemazino eshinda akanyorwa mumiyero haashandi kune ese akakosha esimbi ekurangarira mari, kunyanya ekutanga akapihwa yekurangarira.
Maitiro ekuzivikanwa kwemari yakakosha yesimbi yekurangarira
Kushandiswa kwemari yesimbi inokosha yechirangaridzo kunonyanya kusanganisira jecha, kupfapfaidza bead, girazi pamusoro, mifananidzo isingaonekwe uye zvinyorwa, mifananidzo midiki uye zvinyorwa, kudhinda kwemavara kudhinda/kupfapfaidza, nezvimwewo. Parizvino, simbi dzinokosha dzechirangaridzo dzinowanzo kupihwa zvese zviri zviviri sandblasting uye. mirror finish process. Iyo sandblasting/bead yekupfapfaidza maitiro ndeye kushandisa huwandu hwakasiyana hwejecha zvidimbu (kana mabheji, zvakare uchishandisa lasers) kupfapfaidza magiraidhi akasarudzwa kana nzvimbo dzemuumbu munzvimbo ine chando, kugadzira jecha uye matte maitiro pamusoro pechiyeuchidzo chakadhindwa. coin. Iyo girazi maitiro anowanikwa nekupukuta pamusoro pechifananidzo che mold uye keke kugadzira kupenya kwakajeka pamusoro peiyo yakadhindwa yekurangarira coin.

Zvakanakisisa kuenzanisa mari chaiyo nechigadzirwa chinofanirwa kuonekwa, uye ita kuenzanisa kwakadzama kubva kune zvakasiyana-siyana. Maitiro ekuyamura ari kumashure kwemari inokosha yekurangarira yesimbi anosiyana zvichienderana nedingindira reprojekiti, zvichiita kuti zviome kusiyanisa chokwadi kuburikidza nekuyamura kumusana pasina kuenderana chaiko mari kana yakakwirira-tsanangudzo mapikicha. Kana mamiriro ekuenzanisa asina kusangana, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune zororo, sandblasting, uye girazi kugadzirisa mhedzisiro yezvigadzirwa zvichaonekwa. Mumakore achangopfuura, mari zhinji dzegoridhe nesirivheri dzakapihwa dzakamisikidza mapeteni ekuyamura pane yakashata yeTembere yeKudenga kana chiratidzo chenyika. Vaunganidzi vanogona kudzivirira njodzi yekutenga mari dzemanyepo nekutsvaga nekuziva nemusoro maitiro eiyi yakajairika maitiro.

Mumakore achangopfuura, dzimwe mari dzenhema dzakawanikwa dziine maitiro ekuyamura mberi ari pedyo nemari chaiyo, asi kana zvakanyatsozivikanwa, unyanzvi hwavo huchiri hwakasiyana zvikuru nemari chaiyo. Iko jecha rinoputika pamusoro pemari chaiyo rinopa chimiro chakafanana, chakapfava, uye chakaturikidzana. Imwe laser sandblasting inogona kucherechedzwa mune yegridi chimiro mushure mekukwidziridzwa, nepo jecha mhedzisiro pamari yekunyepedzera yakaoma. Pamusoro pezvo, girazi repamusoro remari chaiyo rakati sandara uye rinoratidza segirazi, nepo girazi repamusoro pemari yekunyepedzera kazhinji rine makomba nemapundu.
