Ukusebenza okugqwesileyo kwezixhobo zokulinganisa i-granite: abagcini bendalo bokuchaneka
I-Granite lilitye lendalo elenziwe ngeenkqubo zejoloji kwiminyaka engamakhulu ezigidi. Ulwakhiwo lwayo lwangaphakathi luxinene kwaye lufana, kwaye ineempawu ezininzi ezifanelekileyo zokucubungula ngokuchanekileyo. Okokuqala, i-coefficient yokwandiswa kobushushu be-granite iphantsi kakhulu, idla ngokuqala kwi-5 ukuya kwi-7×10⁻⁶/℃. Olu phawu luyenza ikwazi ukugcina uzinzo oluphezulu kwindawo yokucubungula enotshintsho olukhulu lobushushu. Ekucutshungulweni kwezinto ze-aerospace, ubushushu obuveliswa kukusebenza kwezixhobo kunye nokuguquguquka kobushushu bendalo akunakuphepheka. Izixhobo zokulinganisa ezenziwe ngezinto eziqhelekileyo zinokubangela iimpazamo zokulinganisa ngenxa yokwanda kobushushu kunye nokucutheka, ngelixa izixhobo zokulinganisa i-granite zingachaphazeleki phantse kutshintsho lobushushu kwaye zihlala zibonelela ngedatha yokulinganisa echanekileyo nethembekileyo, ukuqinisekisa ukuba ukuchaneka kokucubungula akuphazanyiswa ziimeko zobushushu.
Okwesibini, i-granite inokumelana nokuguguleka okuhle kakhulu kunye nobunzima obuphezulu, kunye nobunzima be-Mohs ukuya kuthi ga kwi-6 ukuya kwi-7. Ngexesha leenkqubo zokulinganisa rhoqo, izixhobo zokulinganisa i-granite aziguguleki kwaye zinokugcina ukuchaneka kwazo ixesha elide. Ukucubungula izinto ze-aerospace kudla ngokufuna inani elikhulu lemisebenzi yokulinganisa. Ukumelana nokuguguleka kwezixhobo zokulinganisa i-granite kuzenza zikwazi ukugcina ubungakanani kunye neemilo ezichanekileyo nokuba zisetyenziswe ixesha elide, okunciphisa kakhulu iindleko zokutshintshwa kwezixhobo kunye nokugcinwa kwazo.
Ukongeza, i-granite ikwasebenza kakuhle kakhulu ekuthinteleni ukungcangcazela. Kwiiworkshops zokwenza izinto ngeenqwelo moya, ukusebenza kwezixhobo ezahlukeneyo zokucubungula kuvelisa ukungcangcazela ukuya kumanqanaba ahlukeneyo, okunokuchaphazela ukuchaneka kokulinganisa. Izixhobo zokulinganisa i-granite zinokufunxa ngempumelelo kwaye zinciphise ukungcangcazela kwangaphandle, zibonelela ngendawo ezinzileyo yenkqubo yokulinganisa kwaye ziqinisekise ukuchaneka nokuthembeka kweziphumo zokulinganisa.
Izicelo eziphambili zezixhobo zokulinganisa i-granite ekucutshungulweni kwezinto ze-aerospace
Ukucutshungulwa kwezinto eziphambili zeenjini ze-aero
Njenge "ntliziyo" yenqwelo-moya, injini yeenqwelo-moya ineemfuno eziphezulu kakhulu zokuchaneka kokucubungula kwamacandelo ayo. Umzekelo, ukuchaneka kobume kunye nobukhulu beebhleyidi zenjini kuchaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokutyhala kwenjini.
