Mhangura - Zvinotsanangurwa, Zvivakwa, Zvikamu uye Makirasi

Mhangura ndiyo simbi yekare kudarika dzose inoshandiswa nevanhu.Kushandiswa kwacho kwakatangira panguva dzeprehistoric.Mhangura yakacherwa kweanopfuura makore 10,000 neCopper pendant yakawanikwa muzuva razvino Iraq ichiitwa ku8700BC.Pakazosvika 5000BC Mhangura yakanga ichinyungudutswa kubva kuCopper Oxides iri nyore.Mhangura inowanikwa sesimbi yemuno uye mune zvicherwa cuprite, malachite, azurite, chalcopyrite uye bornite.
Iyo inowanzovawo ne-chigadzirwa chekugadzirwa kwesirivha.Sulphides, oxides uye carbonates ndiwo anonyanya kukosha ores.Mhangura nemhangura alloys ndezvimwe zvezvinhu zvakasiyana-siyana zveinjiniya zviripo.Iko kusanganiswa kwezvinhu zvemuviri zvakadai sesimba, conductivity, corrosion resistance, machinability uye ductility inoita mhangura yakakodzera kune zvakasiyana-siyana zvekushandisa.Izvi zvivakwa zvinogona kuwedzera kukwidziridzwa nekusiyana kwekuumbwa uye nzira dzekugadzira.

Building Industry
Iyo yakanyanya kuguma kushandiswa kwemhangura iri muindasitiri yekuvaka.Mukati meindasitiri yekuvaka kushandiswa kwemhangura yakavakirwa zvinhu yakafara.Indasitiri yekuvaka inoenderana nezvikumbiro zvemhangura zvinosanganisira:

Roofing
Cladding
Mvura inonaya masisitimu
Heating systems
Mapombi emvura uye mafittings
Mafuta uye gasi mitsetse
Wiring yemagetsi
Indasitiri yekuvaka ndiyo yakakura mutengi wemhangura alloy.Rondedzero inotevera kuparara kwekushandiswa kwemhangura neindasitiri pagore:

Kuvaka indasitiri - 47%
Zvigadzirwa zvemagetsi - 23%
Zvekufambisa - 10%
Zvigadzirwa zvevatengi - 11%
Michina yemaindasitiri - 9%

Zvekutengeserana Zvinoumba Mhangura
Kune akatenderedza 370 kutengeserana nziyo dzemhangura alloy.Iyo yakajairika giredhi inoita kunge C106/CW024A - yakajairwa mvura chubhu giredhi yemhangura.

Kushandiswa kwepasi rose kwemhangura nemhangura alloy zvino kwapfuura matani emamiriyoni gumi nemasere pagore.

Zvishandiso zveMhangura
Mhangura nemhangura alloy inogona kushandiswa mumhando inoshamisa yemashandisirwo.Zvimwe zvezvikumbiro izvi zvinosanganisira:

Mitsara yekufambisa magetsi
Architectural applications
Kubikira midziyo
Spark plugs
Wiring dzemagetsi, tambo uye mabhasi
High conductivity waya
Electrodes
Heat exchangers
Refrigeration tubing
Plumbing
Mvura yakanyoroveswa yemhangura crucibles
