Ukukhiqizwa kweketanga namuhla kudinga ukunemba, isivinini, kanye nokuphindeka. Umshini wobuchwepheshe wokwenza iketanga ozenzakalelayo wenza kube lula ukwakheka, ukuluka, ukusika, kanye nokuvala kube ukugeleza kokukhiqiza okuzinzile. Lokhu kunciphisa amaphutha, kuthuthukisa isivuno, futhi kusekela ikhwalithi yeketanga ehambisanayo.

Emshinini wokuphonsa i-vacuum silver bullion , ukushintshwa kwe-oxidation, i-porosity, kanye nobuningi kuyancishiswa ngezimo ze-vacuum ezilawulwayo, kanye nokushisa okunembile kanye nokupholisa okulawulwayo.

Umshini wokwenza ibhola elingenalutho uyithuluzi elinembile elivumela ukukhiqizwa okuphumelelayo kwezingxenye eziyisiyingi ezilula nezisezingeni eliphezulu. Lapho kwakhiwa ukunemba, ukulawulwa komthungo, kanye nokusethwa komshini kuphathwa kahle, abakhiqizi bathola imiphumela ehambisanayo ngokunciphisa ukuchithwa kanye nokuvuselelwa.

Ukuze ukhethe umshini wokukhipha ubucwebe ofanele, umuntu kufanele aqaphele izinto zokwakha, inani lomkhiqizo kanye nezidingo zekhwalithi. Imishini ehlinzeka nge-vacuum engaguquki, ukulawula, izinga lokushisa kanye nesakhiwo esizinzile inikeza imiphumela yokukhipha njalo ngokulungiswa okuncane.

Umshini wokugoqa usebenza kahle kakhulu uma umqhubi eqonda ukuthi ukucindezela, ukunciphisa, kanye nokuziphatha kwezinto ezibonakalayo kuhlangana kanjani. Uma wazi inqubo yokusebenza futhi ugwema amaphutha avamile, uthola ishidi elihlanzekile, amamaki ambalwa, kanye nobukhulu obuhambisanayo.

Izigayo zokugoqa zeGoldsmith ziletha imiphumela emihle kakhulu uma zakhiwe ngokunemba futhi zigcinwa kahle. Igayo elifanele lisiza ekukhiqizeni ishidi elihlanzekile kanye nocingo, linciphisa ukusebenza kabusha, futhi ligcina umkhiqizo uhambisana kuyo yonke imisebenzi.

Kafushane, ubuciko be-granulation yesiliva budinga amathuluzi akhethekile namasu ukuze kuzuzwe imiphumela eyinkimbinkimbi nethambile eye yahlaba umxhwele izingcweti nabathandi bobucwebe emakhulwini eminyaka. Kusukela kuma-granulation kilns namathoshi obucwebe kuya kuzikrini ze-granulation namapuleti e-granulation, ucezu ngalunye lwesisetshenziswa ludlala indima ebalulekile kule nqubo. Ihlanganiswe nekhono elihle lokuhlanganisa izinhlayiya endaweni yensimbi, imbudumbudu yesiliva ihlala iyindlela yobuciko engaphelelwa isikhathi ebonisa ubuhle nobuciko bokwenza ubucwebe. Kungakhathaliseki ukuthi udala amaphethini athambile noma imiklamo enesibindi, ubuciko bezinhlamvu zesiliva buwubufakazi bokuzinikela nobuciko bezingcweti abenza le nqubo yasendulo.

Isihloko: Kwembula Umlingo Womshini Wokugaya Igolide


Wake wazibuza ukuthi ubucwebe begolide benziwa kanjani? Inqubo eyinkimbinkimbi yokuguqula igolide elingahluziwe libe ubucwebe obumangalisayo ihilela izinyathelo ezimbalwa, esinye sazo esiwukusetshenziswa komshini wokugaya igolide. Leli thuluzi elinamandla neliguquguqukayo lidlala indima ebalulekile ekubumbeni nasekucwengeni igolide libe yizicucu ezinhle esizikhonzile. Kule bhulogi, sizongena emhlabeni othakazelisayo wemishini yokugaya igolide, sihlole imisebenzi yayo kanye nezizathu zokuthi kungani ukukhetha umshini ofanele kubalulekile ukuze kuzuzwe imiphumela emangalisayo.


Wenzani Umshini Wokugaya Igolide?


Umshini wokugaya igolide ucezu lwesisetshenziswa esikhethekile esiklanyelwe ukuphatha nokulolonga igolide libe yizinhlobo ezihlukahlukene, njengamashidi, izintambo, namapheshana. Umshini usebenza ngokudlulisela igolide phakathi kochungechunge lwamarola, ucindezela ukuze ucindezele futhi unwebe insimbi. Le nqubo ayishintshi nje kuphela ubukhulu bomzimba begolide kodwa futhi ithuthukisa amandla alo nokuqina.


Omunye wemisebenzi eyinhloko yomshini wokugaya igolide ukunciphisa ukujiya kwegolide, okuholela emashidini amancane noma izintambo ezingase zenziwe kabusha zibe imiklamo eyinkimbinkimbi. Ukwengeza, umshini ungadlulisela ukuthungwa namaphethini ahlukene egolideni, wengeze ukujula nohlamvu emkhiqizweni wokugcina. Noma ngabe idala izindawo ezibushelelezi, ezipholishiwe noma amaphethini aqoshiwe, ukuguquguquka komshini wokugaya kuvumela ama-artisan ukuthi akhulule ubuhlakani bawo futhi enze imiklamo yawo iphile.


Ngaphezu kwalokho, umshini wokugaya igolide uwusizo ekucwengisiseni ubumsulwa begolide. Ngenqubo eyaziwa ngokuthi i-annealing, umshini ungashisisa igolide libe amazinga okushisa aphezulu, ukhiphe ukungcola ngempumelelo futhi uthuthukise ikhwalithi yawo iyonke. Lesi sinyathelo esibalulekile siqinisekisa ukuthi igolide elisetshenziswa ekwenzeni ubucwebe lihlangabezana namazinga aphezulu okuhlanzeka nokucwebezela.

Ukukhipha igolide empeleni kunzima impela, imvamisa yizinkampani ezineziqu ezifanele kuphela ezingakwenza. Uma kungumuntu oyedwa, kusenzima impela ngoba ukukhipha igolide kudinga amathuluzi amaningi kanye namakhemikhali athile. Ukucwengwa kwegolide ikakhulukazi kuhilela ukususa ukungcola, ukuthuthukisa ubumsulwa begolide, nokuhlangabezana nezindinganiso zekhwalithi ukuze kuhlangatshezwane nezidingo zokuhweba ezimakethe. Njengamanje, izindlela eziyinhloko zokukhipha igolide kwa-Shenzhen Hasung Precious Metals Equipment Co., Ltd zifaka ukuhlanzwa kwe-chlorination, ukuhlanzwa kwe-aqua regia, ukuhlanzwa kwe-electrolysis, ukuhlanzwa kwe-chloramine, njll.

Embonini yokuphonsa insimbi eyigugu, ukunemba nokusebenza kahle kunquma ukuncintisana okungumongo wenkampani. Izinqubo zokukhiqiza zegolide zendabuko, ezikhungethwe amaphutha okukala, ukonakala kwendawo, nokungaqini kwenqubo, sekunesikhathi eside kuhlupha abakhiqizi abaningi. Manje, ake sibheke uchwepheshe ikhambi lenguquko—Ulayini Wokusakaza Webha Yegolide le-Hasung—futhi sibone ukuthi ulichaza kanjani kabusha izinga lokugqwesa ekufakweni kwegolide ngobuchwepheshe obusha.

Igolide nesiliva bekuyizimpawu zengcebo, ukulondolozwa kwenani kanye nokunethezeka kusukela ezikhathini zasendulo. Kusukela kuma-ingots egolide asendulo kuya emigoqweni yegolide yokutshalwa kwezimali yesimanje, abantu abakaze bayeke ukuwalandela. Kodwa uke wacabanga ngomehluko phakathi kwezinto ezingavuthiwe zebha yegolide yokutshalwa kwezimali yezinga eliphezulu nobucwebe begolide obujwayelekile? Impendulo ilele “kubumsulwa” kanye “nobuqotho”. Isihluthulelo sokuthola ubumsulwa obukhulu idivayisi yobuchwepheshe obuphezulu ebizwa ngokuthi "i-vacuum ingot casting machine". Isungula buthule indlela yokukhiqiza yezinsimbi eziyigugu futhi isakaza isizukulwane esisha samafa.
