Izindaba

As imishini yobucwebe begolideumenzi, sabelana ngolwazi lobucwebe begolide kumakhasimende.

Igolide lixutshwa nezinsimbi ezifana nethusi nesiliva uma lisetshenziselwa ukwenza ubucwebe. Igolide elimhlophe aliyona into ngokwayo, kodwa liyigolide elixutshwe nezinye izinsimbi ukuze lidale ukubukeka kwesiliva. Izinsimbi ezisetshenziswa kakhulu egolide elimhlophe yi-nickel ne-palladium, noma ngisho ne-zinc noma i-tin.

UKUXUBISA AMA-ALLOY OKUSEBENZISA UBUHLOBO

Uyazi ukuthi yiziphi izinsimbi ozigqokile?

Ungase umangale ukwazi inani lezinsimbi ezahlukene kanye nama-alloy angene ebucwebeni bakho nasemzimbeni wakho. KwaWilliam Rowland siyaziqhenya ngokuhlinzeka ngezinsimbi nama-alloy ahlanzekile kakhulu ezimbonini ezahlukene emhlabeni jikelele.

Izinhlobo zensimbi eziyinhloko esizicabangayo uma kukhulunywa ngokwenza ubucwebe yisiliva negolide, kodwa empeleni ubucwebe obuningi abukwenziwa ngesiliva noma igolide elihlanzekile. Isizathu salokhu ukuthi ngezindlela zazo ezimsulwa kakhulu, isiliva negolide kokubili kuthambile kakhulu ukuthi kungafanelekela ubucwebe obuningi. Zonke izinsimbi zinezakhiwo ezihlukile ezenza zifanelekele imisebenzi ethile, yingakho kubalulekile ukukhuluma nomhwebi wensimbi onolwazi lapho u-oda.

Uhlobo lwesiliva oluhlanzekile kakhulu lubizwa ngokuthi 'isiliva elihle' futhi lokhu kusetshenziselwa kakhulu i-bullion, hhayi ubucwebe noma imali, ngoba ithambile. Isiliva nalo lisengozini enkulu yokungcoliswa, futhi ukuxuba nezinye izinsimbi kungakuvimbela lokhu. Esikhundleni salokho, kusetshenziswa i-alloy, isiliva esithambile esikhundleni salokho. Lokhu kuhlanzekile ngo-92.5%, kodwa okusele kuxutshwa nezinye izinsimbi ezifana nethusi, i-zinc noma i-silicon.

Ngokufanayo, igolide elisesimweni salo esimsulwa livame ukugcinelwa i-bullion, ngoba lithambile futhi lingaguquka kalula libe ubucwebe noma imali. Igolide lixutshwa nezinsimbi ezifana nethusi nesiliva uma lisetshenziselwa ukwenza ubucwebe. Igolide elimhlophe aliyona into ngokwayo, kodwa liyigolide nje elixutshwe nezinye izinsimbi ukuze kubonakale isiliva. Izinsimbi ezisetshenziswa kakhulu egolide elimhlophe yi-nickel ne-palladium, noma ngisho ne-zinc noma i-tin.

Kukhona futhi izingxube ezahlukene zegolide ukudala imibala nemiphumela ehlukene. Igolide le-rose liyingxube yegolide eliphuzi, isiliva nethusi, ukudala umbala opinki, futhi izinhlanganisela ezintsha zensimbi ze-alloy zobucwebe zihlala zitholakala.

KwaHasung siyayazi insimbi futhi njengoba besilokhu sikhiqiza imishini yensimbi eyigugu kusukela ngo-2000, sinokuqonda okuhlukile ngezakhiwo zayo kanye nokufaneleka kwayo kuzo zonke izinhlelo zokusebenza. Uma uthenga insimbi ngemakethe, kungaba ngokubeka i-oda esitolo esiku-inthanethi, noma enkampanini yensimbi yendawo, qiniseka ukuthi uthola insimbi efanele, ngokusebenzisa i-Isihlaziyi se-XRF, uzoba nengqondo ehluzekile ukuze uthole izinsimbi ezifanele ozidingayo.
