Namhlanje, abavelisi banikela abathengi ngebhajethi elinganiselwe ubuninzi bezinto zokugqoka ezenziwe ngezinto ze-analog. Ingaba i-tin, i-aluminium, i-nickel kunye nobhedu. Kodwa ezona zidume kakhulu zazingezobucwebe ezenziwe nge-alloy yezokwelapha, ezinempahla eninzi encedo. Ayicasuli isikhumba, ayibangeli ubundlobongela, kwaye ugcina umbala ocebileyo kwaye ukhanyise ixesha elide. Nangona kunjalo, akufuneki ukuba umntu acinge ukuba iingubo zokugqoka iingubo ezivela kwi-medical steel is analogue egcweleyo yezinto ezikhethekileyo zenziwe ngeensimbi ezixabisekileyo. Ukukhawuleza kwangoko okanye emva koko kuqala ukutshabalalisa nokulahlekelwa kwindlela yokubonakala ngayo, ngoko ngokuhamba kwesikhathi kuya kufuneka badluliselwe endaweni okanye baxolelane kunye nokusilela kwabo.
I-bijouterie eyenziwe yensimbi yonyango ayimelana ne-acids kunye ne-alkalis enobudlova, ayifaki kwaye ayifuni ukuthungca umsila, oba ngumhlaba ofanelekileyo wokuzalisa i-microbes.
Ukwahlulelwa kweelithi
"Ingubo yokugcoba ngezokwelapha" yinkcazo esetyenziselwa ukukhohlisa abathengi. Enyanisweni, abakhiqizi basebenzisa ubucwebe ezi zilandelayo:
- I-Zinc alloy in jewelry fashion. Ngokuqhelekileyo kusetyenziswa ngabaphathi beenkampani zaseCzech. I-alloy ibandakanya i-10% ye-zinc kunye ne-90% yobhedu. Le ngcaciso ayiqukethe i-nickel eyingozi, eyingozi kumzimba.
- Igolide yezobisi kwiingubo zokugqoka iimpahla. Enyanisweni, ingqiqo ye "golide yezokwelapha" ifakwe ngabathengisi bezinto ezidityanisiweyo abathembele ekuhlaseleni nokungazi umthengi. Indima yegolide kwimveliso enjalo iyenziwa ngethusi ye-hypoallergenic.
- Imihlobiso yokwakha. Iimveliso ezinjalo ziphantse kakhulu kwizinto zokugqoka, kunokuba zibe ziigugu, kuba zineziganeko zegolide, nokuba zizona zincinci. Qaphela ukuba negolide yegolide ihlamba ngaphezu kwexesha.
Ukuba usenokugqiba ukuthenga iingubo ngegolide elandelelanayo, ngoko ulungiselele ukuba ekugqibeleni kuya kufuneka kuthathelwe indawo. Ukwandisa ubomi babo, gcina iimveliso kwindawo ezinomileyo kwaye ugweme amanzi angcolileyo.
