Ama-rivets okuqala kwakuyizikhonkwane ezincane ezenziwe ngokhuni noma ngethambo.Umzimba wokuqala we-metal deformation ungaba ukhokho wama-rivets esiwaziyo.Akungabazeki ukuthi ziyizindlela zasendulo zokuxhuma insimbi ezaziwa esintwini, ezingalandelelwa emuva ekusetshenzisweni kokuqala kwensimbi ethambileyo.Isibonelo, ngeNkathi Yethusi, abaseGibhithe bagingqa futhi babopha imizimba yabalandeli eyisithupha yokhuni yomugqa wangaphandle wesondo elicijile kanye nama-rivets.Ngemva kokuba amaGreki ephonse ngempumelelo izithombe ezinkulu zethusi, ahlanganisa izingxenye kanye nama-rivets.Njengamanje, kunezinhlobo eziningi zokuthuthukiswa kwe-rivet, ikakhulukazi ukuthuthukiswa kwamabhizinisi ahlukahlukene.
"Izingxenye ezijwayelekile zensimbi engagqwali" umqondo othize wethemu ohlanganisa imikhiqizo eminingi.Izingxenye ezijwayelekile zensimbi engagqwali zivame ukusetshenziselwa ukubopha izingxenye zomshini ezibiza kakhulu ngenxa yobuhle bazo, ukuqina, ukumelana nokugqwala okuqinile nezinye izici.Ngokuthuthuka komphakathi, izidingo eziphezulu nazo zibekwe phambili zezingxenye ezijwayelekile zensimbi engagqwali.Izingxenye ezijwayelekile zensimbi engagqwali ziphinde zibhekisele kuzikulufu zensimbi engagqwali, okuyizikulufu ezijwayelekile.Ukucaciswa, ubukhulu kanye nobubanzi bokubekezelela wonke amazinga kazwelonke.
Izingxenye ezijwayelekile zensimbi engenasici zinezidingo zazo zezinto zokukhiqiza.Izinto eziningi zensimbi engagqwali zingenziwa zibe izintambo zensimbi noma imigoqo yokukhiqiza okokuqinisa, okuhlanganisa i-austenitic stainless steel, i-ferritic stainless steel, i-martensitic stainless steel kanye nemvula eqinisa insimbi engagqwali.Ngakho-ke yiziphi izimiso lapho ukhetha izinto zokwakha?Ukukhethwa kwezinto zensimbi engagqwali kucatshangelwa ikakhulukazi kulezi zici ezilandelayo:
1. Izidingo zezakhiwo zemishini, ikakhulukaziamandla ezinto zokubopha;
2. Izidingo zezimo zokusebenzaukumelana nokugqwala kwezinto;
3. Izidingo zokushisa okusebenzayo ekuphikiseni ukushisa (amandla okushisa aphezulu, ukumelana ne-oxidation) kwezinto;
4. Izidingo zokusebenza kokucubungula impahla ngokobuchwepheshe bokukhiqiza;
5. Ezinye izici, njengesisindo, intengo nokuthenga, kufanele kucatshangelwe.
