1. Izinto ezenziwe ngegolide: Kuthatha isilika yegolide njengesiseko, kwaye umphezulu wayo ugqunywe ngumaleko wegolide evulekileyo (K).Kukho imibala emibini yegolide evulekileyo: igolide emhlophe kunye negolide ephuzi.
A. igolide
Le yintsimbi yegolide ene-ductility elungileyo kwaye phantse akukho discoloration oxidative.Kuba igolide esulungekileyo (24K) ithambile kakhulu, xa usebenzisa igolide njengesakhelo sokubukela.Ixutywe kunye nezongezelelo ezifana nentsimbi kunye nesilivere ukuyenza ibe yi-alloy ukunciphisa ibakala kunye nokwandisa amandla kunye nokuqina.Isiqulatho segolide seefreyimu zemiboniso ngokuqhelekileyo yi-18K, 14K, 12K, loK.
B iplatinam
Le yintsimbi emhlophe, inzima kwaye iyabiza, kunye nococeko lwe-95%.
2. Vula igolide kunye nepakethe yegolide
A. Yintoni igolide evulekileyo?Into ebizwa ngokuba yi (K) igolide asiyogolide esulungekileyo, kodwa yingxubevange eyenziwe ngegolide esulungekileyo nezinye iintsimbi.Igolide ecocekileyo yigolide engazange idityaniswe ngokupheleleyo (oko kukuthi, ayifakwanga kwezinye iintsimbi).Igolide evulekileyo esetyenziswa kwishishini ibhekisa kumlinganiselo wegolide esulungekileyo kwezinye iintsimbi ezikwi-alloy, echazwe ku-(K) amanani, echazwa njengephindwaphindwa kwisinye kwisine sobunzima bubonke begolide, ngoko ke i-24K yegolide yiGolide esulungekileyo. .I-12K igolide yialloyi enamalungu alishumi elinesibini egolide esulungekileyo kunye neenxalenye ezilishumi elinesibini zezinye isinyithi, kwaye i-9K yegolide yialloyi eneenxalenye ezilithoba zegolide esulungekileyo kunye neshumi elinesihlanu lezinye iintsimbi.
B. Gild
I-Gold-clad yintsingiselo yomgangatho.Ekwenziweni kwegolide, enye ingqimba yesiseko yesinyithi ihlanganiswe kunye nenye igolide evulekileyo, kwaye inkcazo yokugqibela yezinto eziphathekayo ngumlinganiselo wegolide evulekileyo esetyenziswayo kunye nenani legolide evulekileyo.
Zimbini iindlela zokubonisa ukwaleka kwegolide: isinye eshumini se-12 (K) sithetha ukuba isinye eshumini sobunzima besakhelo yigolide eyi-12K;enye ibonakaliswa yigolide esulungekileyo ekwimveliso egqityiweyo;igolide enye yeshumi ye-12K ingabhalwa njenge-5/100 yegolide ecocekileyo (kuba i-12K yegolide iqulethe i-50/100 yegolide ecocekileyo).Ngokufanayo, igolide ye-10K yamashumi amabini ananye ingabhalwa njenge 21/looo yegolide esulungekileyo.Ngokulinganisa, zombini igolide etyheli kunye nemhlophe inokusetyenziswa ukwenza iifreyimu ezihonjiswe ngegolide.
3. Izinto ze-alloy yobhedu
I-alloys zobhedu ezibaluleke kakhulu zibhedu, i-bronze, i-zinc cupronickel, njl., kunye ne-brass kunye ne-cupronickel zisetyenziswa ngokuqhelekileyo kwimboni yeeglasi.
A. Copper nickel zinc alloy (zinc cupronickel)
Ngenxa yobuchule bayo obuhle (i-machinability, i-electroplating, njl.), ingasetyenziselwa zonke iindawo.Yi-alloy ye-ternary equlethe i-Cu64, i-Ni18, kunye ne-Znl8.
B. Ubhedu
I-alloy ye-binary equkethe i-cu63-65% kwaye enye i-zn, kunye ne-yellow hue.Ukungalungi kukuba kulula ukutshintsha umbala, kodwa ngenxa yokuba i-chip ilula ukuyiqhuba, ingasetyenziselwa ukwenza iimpumlo zempumlo.
C. Copper nickel zinc tin alloy (Bran Kas)
Kule alloy ye-quaternary equlethe i-Cu62, i-Ni23, i-zn1 3, kunye ne-Sn2, ingasetyenziselwa i-silika emphethweni kunye neesimboli ezimile njengefektri ngenxa yokuqina kwayo okugqwesileyo, iipropati ze-electroplating kunye nokumelana nokugqwesa okugqwesileyo.
D. Ubhedu
Le yi-alloy ye-Cu kunye ne-sn alloys eneempawu ezahlukeneyo ngokomlinganiselo we-sn equlethwe.Xa kuthelekiswa nobhedu, kuba iqulethe i-tin sn, ibiza kakhulu kwaye inzima kakhulu ukuyiqhuba, kodwa ngenxa ye-elasticity yayo egqwesileyo, ifanelekile kwizinto eziphathekayo zocingo, kwaye i-disadvantage kukuba i-corrosion resistant.
E. I-alloy ye-nickel-copper yamandla aphezulu-amandla anganyangekiyo
Le yi-alloy equkethe i-Ni67, i-CU28, i-Fc2Mnl, kunye ne-5i.Umbala umnyama namhlophe, unokumelana ne-corrosion enamandla kunye no-elasticity obuthathaka.Ifanelekile kwindandatho yesakhelo.
Phantse zonke ezi ntlanu zingentla ialloys zobhedu zingasetyenziswa njenge-primer yezixhobo zegolide kunye ne-primer ye-electroplating kwiifreyimu ze-spectacle eziveliswa ekhaya nakwamanye amazwe.
4.Stainless Steel
Le yingxubevange equlethe iFe, Cr, kunye neNi.Ukumelana ne-corrosion elungileyo, eneempawu ezahlukeneyo ezinezongezo ezahlukeneyo.I-elasticity ephezulu, esetyenziswa njengeetempile kunye nezikrufu.
5. Isilivere
Iifreyimu ezindala kakhulu zenziwe nge-alloy yesilivere.Kuphela ziiglasi zasemzini eziphathwa ixesha elide kunye nezinye zokuhombisa iiglasi-kwiiglasi ezisasetyenziswa njengemathiriyeli ekrwada kwezi zanamhlanje.
6. Aluminiyam anodized
Izinto eziphathekayo zikhaphukhaphu, ziyakwazi ukumelana ne-corrosion, kwaye umaleko wangaphandle we-alumina unokunyusa ukuqina kwezinto.Kwaye inokudaywa ibe yimibala eyahlukeneyo etsala amehlo.
7. Nickel yesilivere
Isebe lobhedu kunye ne-nickel alloy, uze ungeze i-zinc bleaching.Yenza imbonakalo yesilivere, ngoko ikwabizwa ngokuba "isilivere yangaphandle".Yomelele, iyamelana nomhlwa, kwaye inexabiso eliphantsi kunelegolide.Ngoko ke, inokusetyenziswa njengesakhelo somntwana.Emva kokuba isakhelo senziwe, i-nickel plating ecocekileyo isetyenziswa ukwenza ukubonakala kuqaqambe.
8.Titanium (Ti)
Le yintsimbi enobunzima obukhanyayo, ekwaziyo ukumelana nobushushu, kunye ne-corrosion-resistant, eye yatsala umdla kumashishini ahlukeneyo.Ukungalungi kukuba kukho izinto ezininzi ezichaphazela ukungazinzi kwendawo yomatshini.
9. I-Rhodium plating
I-Electroplating rhodium kwisakhelo segolide etyheli, imveliso egqityiweyo yisakhelo segolide esimhlophe esingeyiyo into yentsimbi kunye nemathiriyeli eyenziweyo esebenza ngokuzinzileyo kunye nenkangeleko eyanelisayo.
