925 Ubucwebe beSilivere

Ubucwebe besilivere buba zezona ntlobo zixhaphakileyo zezacholo ezithengwa ngabantu. Ekunene ukusuka kwizacholo, amakhonkco, amacici ukuya kumakhubalo, ipendants, njl. Ubucwebe besilivere benza izipho ezimangalisayo zokuzalwa kunye nesikhumbuzo.

E-United States, i-US Federal Trade Commission (FTC) ichaze ukuba isilivere ayinakuthengiswa njengesilivere, isilivere enqabileyo, isilivere enqabileyo, isilivere eqinile, okanye kunye nesifinyezo se-Ster., ngaphandle kokuba iquka ubuncinane i-92.5% yesilivere ecocekileyo. Kodwa, yintoni le 925 yesilivere? Kutheni kunyanzelekile ukuthenga isilivere kweli bakala?

Yintoni i ?

Isilivere esulungekileyo (i-99% yesilivere) ithambile, i-ductile, kwaye ithambile kakhulu. Ukuthamba kwayo kwenza kube lula ukusebenza nayo. Nangona kunjalo, iphinda ikrwelwe ngokulula. Kwimo yayo ecocekileyo, isilivere yintsimbi ehloniphekileyo kwaye ikwabiza kakhulu.

Nangona kunjalo, kuba ikrweleka ngokulula, ayifanelekanga ukwenza izinto ezisebenzayo. Kumsebenzi omnye okanye emibini, iphuhlisa inkangeleko edliweyo neneziphene. Ngaloo ndlela, i-alloy yesilivere yenziwa.

I-92.5% yentsimbi yesilivere ixutywe kunye ne-7.5% yentsimbi yobhedu ukufumana i-925 yesilivere enqabileyo. I-7.5% yobhedu eyongeziweyo inika isilivere amandla afunekayo afunekayo. Ekubeni kuphela i-7.5% yobhedu yongezwa, kunye ne-92.5% eseleyo umxholo njengesilivere, i-ductility kunye ne-charm yensimbi yesilivere igcinwe.

Ngaphandle kobhedu, ezinye iintsimbi ezifana negermanium, iplatinam, kunye nezinki nazo zinokongezwa kwisilivere ukwenza isilivere eqaqambileyo. Nangona kunjalo, ngokubhekiselele kwimigangatho yoshishino, i-925 yesilivere ye-sterling ilungiselelwe kuphela ngokongeza isinyithi sobhedu.

Isilivere ye-925 ayibizi njengesilivere esulungekileyo kwaye iyafikeleleka. Isetyenziselwa ukulungisa iintlobo ezahlukeneyo zobucwebe besilivere njengamacici, iintsimbi zomqala, amakhonkco, amakhonkco empumlo, izacholo, i-ankle, njl.

Ubucwebe obunesiphumo buhlala buhlala kwaye buxhathisa kunezacholo zesilivere ezicocekileyo. Ngaphezu koko, xa amatye anqabileyo efakwe kwi-, ixabiso layo landa ngakumbi.

Uya kufumana izitena ezininzi ezaziwayo kunye neevenkile ze-intanethi ezithengisayo. Bajongana nabathengi abakhulu abafuna ubucwebe obufikelelekayo.

Rhoqo, isaphulelo sesilivere engama-925 sikwakhona nesifumaneka ngexabiso eliphantsi. Kukho zonke iintlobo zoyilo ezikhoyo kwaye ukuba awukavuyi, unokuba nobucwebe bakho benziwe ngokwesiko ukuze bulungele incasa yakho kunye nokhetho lwakho.

Intsimbi yesilivere efana negolide yintsimbi ebekekileyo engaphenduliyo okanye i-oxidize xa idibene neesulfides emoyeni. Nangona kunjalo, ekubeni ubucwebe esibuthengayo , masingalibali ukuba iqukethe ubhedu.

Izinyithi ezifana nobhedu, i-zinc, kunye ne-nickel zifakwa i-oxidized yi-sulfide emoyeni kwaye zibe mnyama. Yi-oxidation yobhedu kwizacholo ezibangela ukuba iqhekeza lezacholo zesilivere zibe mnyama kwaye zibe mdaka emva kwexesha elithile. I-yellowing yesilivere yimpendulo eguqukayo, kwaye i-sheen inokubuyiselwa ngokugulisa isinyithi.

Ukucothisa isantya apho ubucwebe bakho besilivere buba tyheli, gcina ubucwebe bukude kwindawo efumileyo nefumileyo. Oku kunokwenziwa ngokuzigcina kwizikhongozeli ezingangeni moya okanye kwiingxowa zokuthintela ukubola.

Ngaphezu koko, emva kokusetyenziswa ngakunye, zicoce ngelaphu. Ufumana iingubo ezikhethekileyo zokucoca ngeenjongo ezinjalo, ezingcono kuneengubo eziqhelekileyo. Ungasebenzisa nasiphi na isicoci sezacholo zesilivere okanye ipolishi eyenziwe ekhaya ukubuyisela i-sheen kumaxesha ngamaxesha.

Abantu banxibe ubucwebe besilivere ukususela ngo-900 BC. ifanelekile kumntu wonke kungakhathaliseki ubudala okanye isini. Isibheno saso sakudala asizange siphume kwisitayile! Isilivere ye-925 ngumgangatho obekwe ngabachwephesha ukubonisa isilivere esemgangathweni. Ke, kwixesha elizayo xa uyokuthatha ubucwebe besilivere, qiniseka ukuba yiyo!
