Iindaba

As oomatshini begolide bokuhombisaumenzi, sabelana ngolwazi lobucwebe begolide kubathengi.

Igolide ixutywa neentsimbi ezifana nekopolo nesilivere xa isetyenziselwa ukwenza ubucwebe. Igolide emhlophe ayisiyonto ngokwayo, kodwa yigolide nje exutywe nezinye iintsimbi ukwenza inkangeleko yesilivere. Iintsimbi ezisetyenziswa kakhulu kwigolide emhlophe yi-nickel kunye ne-palladium, okanye i-zinc okanye i-tin.

UKUXUBA II-ALLOY ZOKWENZA UBUCIKO

Uyazi ukuba zeziphi iintsimbi ozinxibileyo?

Ungamangaliswa kukwazi inani leentsimbi ezahlukeneyo kunye nee-alloys eziye zangena kubucwebe bakho nasemzimbeni wakho. Apha eWilliam Rowland siyazingca ngokubonelela ngeentsimbi kunye nee-alloys ezicocekileyo kakhulu kumashishini ahlukeneyo kwihlabathi liphela.

Iintlobo eziphambili zesinyithi esicinga ngazo xa kufikwa ekwenzeni ubucwebe zesilivere negolide, kodwa eneneni uninzi lobucwebe alwenziwanga ngesilivere okanye igolide ecocekileyo. Isizathu soku kukuba kwiimo zazo ezicocekileyo, isilivere negolide zombini zithambile kakhulu ukuba zingafaneleka kwiicwebe ezininzi. Zonke iintsimbi zineempawu ezizodwa ezenza zifaneleke kwimisebenzi ethile, kwaye yiyo loo nto kubalulekile ukuthetha nomrhwebi wesinyithi onamava xa u-odola.

Uhlobo lwesilivere olusulungekileyo lubizwa ngokuba 'yisilivere entle' kwaye oku kusetyenziselwa kakhulu i-bullion, endaweni yobucwebe okanye imali, kuba ithambile. Isilivere ikwachaphazeleka kakhulu kukungcola, kwaye ukuxuba nezinye iintsimbi kunokuthintela oku. Endaweni yoko, kusetyenziswa i-alloy, isilivere etyheli endaweni yoko. Le inobumsulwa obuyi-92.5%, kodwa okuseleyo kuxutywe nezinye iintsimbi ezifana ne-copper, i-zinc okanye i-silicon.

Ngokufanayo, igolide ekwimo yayo ecocekileyo idla ngokugcinelwa i-bullion, kuba ithambile kwaye ingaguquka ngokulula kwizacholo okanye imali. Igolide ixutywa neentsimbi ezifana nobhedu nesilivere xa isetyenziselwa ukwenza ubucwebe. Igolide emhlophe ayisiyonto ngokwayo, kodwa yigolide nje exutywe nezinye iintsimbi ukwenza inkangeleko yesilivere. Iintsimbi ezisetyenziswa kakhulu kwigolide emhlophe yi-nickel kunye ne-palladium, okanye i-zinc okanye i-tin.

Kukwakho neengxube ezahlukeneyo zegolide ukwenza imibala eyahlukeneyo kunye neziphumo. Igolide yerose yingxube yegolide etyheli, isilivere kunye nobhedu, ukwenza umbala opinki, kwaye kusoloko kufunyanwa iindibaniselwano ezintsha zesinyithi ze-alloy zobucwebe.

Apha eHasung siyayazi isinyithi kwaye ekubeni besisenza izixhobo zesinyithi ezixabisekileyo ukusukela ngo-2000, sinolwazi olukhethekileyo ngeempawu zazo kunye nokufaneleka kwazo kwiintlobo ngeentlobo zezicelo. Xa uthenga isinyithi ngemarike, nokuba ngokubeka iodolo kwivenkile ekwi-intanethi, okanye kwinkampani yesinyithi yasekuhlaleni, qiniseka ukuba ufumana isinyithi esifanelekileyo, ngokusebenzisa i-Isihlalutyi se-XRF, uya kuba nengqondo evulekileyo ukuze ufumane izinyithi ezichanekileyo ozifunayo.
