Yintoni na isampuli zegolide

Loo metal wohlobo ezifana negolide azifane engena isandla kwifomu yayo enyulu. Ngokuqhelekileyo ezo iimveliso ukuba simbiza igolide ngenene intsila zegolide ezihlangene. Ligature sathiwa silinene ubumdaka metal non-ayoni. Ezi elimsulwa ezidityaniswe ingxubevange, ezisetyenziswa ukuphucula intsebenzo kunye nezinye iimpawu eziyimfuneko njengoko ngokwayo intsimbi elixabisekileyo ithambe kakhulu ngendlela yayo enyulu. Gold ngohlobo yayo enyulu ubethwa lingonakali enzima, kwaye iimveliso ukuba aphume kunokwenziwa oku, kuya kuba lula phina yaye ngokufuthi aphule.

Nkqu kumaxesha amandulo, izazinzulu sele uqinisekile ukuba ligature ilungileyo negolide nesilivere nobhedu. Ngoko ke, ukuba kongezwa aluminiyamu wegolide izixa ezahlukeneyo. Kwaye ukuze nibe nako ukwazi inani ezihlangene ongezwe e-aluminium zokwenza izinto baqala ukusebenzisa iisampuli zegolide. Oko kukuthi, ehlabathini namhlanje, umgangatho nayiphi ubucwebe izivatho kwimveliso metal ezixabisekileyo kuxhomekeke kungekhona ngezinto zegolide (ebomvu okanye amhlophe) asetyenziselwa imveliso yawo, kunye nesiqulatho zabo ekungcoleni, obanika amandla ixesha elide.

Inkoliso yezi izacholo zenziwa ka 585 ngegolide. Ezongezelelweyo izinto lokuvelisa ubucwebe ukwahlula zegolide bomvu, qanda, namhlophe. Gold Red iveliswa ngokudibanisa kuso ngobhedu, oko kwandisa amandla ayo elide. Ke ezihlangene mthubi asetyenziswa jikelele isilivere, kwaye bafumane abamhlophe idityaniswe ingxubevange nickel kunye palladium. Kusetyenziswa iindlela ezimbini ukufumanisa ukuba isampuli yegolide - a eqatywe kunye metric. Ngomhla kummandla eRashiya ubukhulu becala kusetyenziswa inkqubo metric, ngokusekelwe ukumiselwa ubunzima metal elixabisekileyo kumawaka iimveliso abaninzi. Ngoko ke lula ukuqonda oko ke iisampuli yegolide. Ngokomzekelo, xa ingxubevange 1000 iqulethe 585 iigram 585 iigram zegolide esulungekileyo baza 415 grams ezihlangene. Ngokufanayo, isampuli imiselwa, negolide emhlophe.

Eqatywe inkqubo Ubhaqo isampuli igolide kakhulu isicelo kwi-UK, iYurophu kunye USA. Kulo mzekelo, ukwalathelwa oluqhutywa carats. Eqatywe kuchazwa enye amabini anesine ubunzima igolide ingxubevange. Ngoko ke metal ecocekileyo oxabisekileyo na 24K, isampuli 750 ingqamana 18K, isampuli 375 liye 9k. Ethandwa kakhulu ehlabathini usebenzisa intsila ngegolide iimvavanyo 750. Phantse naziphi na izinto Gold umbala zenziwa kunye nokusetyenziswa Kwakule sampulu yegolide. Umahluko umbala izacholo ukufezekisa usebenzisa yokuba ekwakhiweni kwezi aluminium zongezeke izinyithi ezahlukeneyo elixabisekileyo - mbala, iridium, rhodium, chromium zinc.

Ngoko ke, kwimarike izacholo namhlanje kukuba ubukho enkulu ngegolide eluhlaza, igolide eluhlaza, igolide, igolide abamnyama, ngokunjalo ngegolide emhlophe. Nangona kunjalo, i ixhaphake kakhulu kodwa ayelo kunye indibanisela ngegolide ebengezelayo and white. Kodwa ke kubomi bemihla ngemihla eziqhele ukufunyanwa aluminium kwiisampuli ezine: 375, 585, 750 kunye 958. Gold ingxubevange iisampulu 958 ngoyena ngokuqhelekileyo kusetyenziswa ekuveliseni imisebenzi yobugcisa. Kukho 900 sample, nto leyo kumazwe amaninzi ukuze zodumo iinkozo ngegolide bamazinyo. Ukuba imihombiso zenziwa aluminium kwiisampuli ngaphantsi kwe 375, ngoko ke saba kucingelwa ukuba nezacholo, zabizwa izacholo.

Kumazwe amaninzi ehlabathini ekuveliseni karhulumente izacholo usebenzisa ulawulo phezu umxholo zegolide aluminium. Kwamanye amazwe nayo ukulawula ngaphezulu bejewellery iinkampani ukuba babe ibala lwabo entsonkothileyo kakhulu kwaye zahlukahlukene. Noko ke, kwamanye amazwe, afana eYiputa, Turkey, i-USA kunye namazwe eMzantsi Merika, akukho ulawulo karhulumente phezu nokuveliswa kwemveliso zegolide.
