2024-04-18 09:52:59
Ka tsoelo-pele e potlakileng ea saense le thekenoloji le ho potlakisa ha metse ea litoropo, marokho, e le karolo ea bohlokoa ea lipalangoang tsa litoropong, a lula a ntlafatsa mekhoa ea bona ea ho qapa le ea kaho. Marokho a tloaelehileng a tšepe a sebelisoa haholo ka lebaka la matla a bona a phahameng le theko e tlaase. Leha ho le joalo, ha nako e ntse e ea, butle-butle mathata a kang kutu le litšenyehelo tse phahameng tsa tlhokomelo a hlaha. Khahlanong le semelo sena, lisebelisoa tse phahameng tsa aluminium alloy li fetohile khetho ea phetoho tšimong ea kaho ea borokho ka melemo ea bona e ikhethang ea ts'ebetso.
Melemo ea lisebelisoa tsa alloy aluminium
Melemo ea moralo o bobebe
Boima ba alloy ea aluminium ke hoo e ka bang 2.7 g/cm³, e ka bang 1/3 feela ea tšepe. Thepa ee e bobebe e bolela eng bakeng sa moralo le kaho ea borokho? Pele ho tsohle, meaho ea borokho e bobebe e ka fokotsa litlhoko tsa metheo, e lumella marokho a maholo hore a hahoe libakeng tse nang le maemo a mabe a jeoloji. Taba ea bobeli, meaho e bobebe le eona e ka fokotsa litšenyehelo tsa lipalangoang le tsa ho kenya, tse bohlokoa haholo libakeng tse hole kapa libakeng tse nang le phihlello e fokolang. Ho phaella moo, mehaho e bobebe e ka boela ea thusa ho ntlafatsa ts'ebetso ea litšisinyeho tsa lefatše nakong ea litšisinyeho tsa lefatše hobane boima bo bobebe bo fokotsa matla a inertial tlas'a ketso ea tšisinyeho ea lefatše.
Bohlokoa ba ho hanyetsa corrosion
Lisebelisoa tsa aluminium alloy li ka etsa filimi e teteaneng ea oxide sebakeng sa tlhaho. Filimi ena ea oxide e ka thibela ka katleho ho kenella ha mongobo le oksijene, ka tsela eo e sireletsa thepa ho tloha ho bola. Sena ke sa bohlokoa ka ho khetheha kahong ea borokho, kaha hangata marokho a pepesehela maemo a leholimo 'me a hloka ho mamella maemo a leholimo. Ha ho bapisoa le marokho a tloaelehileng a tšepe, marokho a aluminium alloy ha a hloke phekolo e khahlanong le kutu khafetsa, a fokotsa haholo litšenyehelo tsa nako e telele tsa tlhokomelo le mosebetsi.
Motsoako o phethahetseng oa polasetiki le ts'ebetso
Lisebelisoa tsa alloy ea aluminium li bonolo ho hlahisa le ho theha, 'me litlaleho tse nang le likarolo tse fapaneng tse rarahaneng li ka etsoa, tse fanang ka menyetla e mengata ea ho etsa borokho. Baqapi ba ka rala meaho e metle le e sebetsang ea borokho kamoo ho hlokahalang ho fihlela litlhoko tse peli tsa litoropo tsa sejoale-joale bakeng sa sebopeho le ts'ebetso. Ho phaella moo, aluminium alloy welding le thekenoloji ea ho hokahanya le tsona li ntse li ntlafala kamehla, ho etsa hore kaho ea marokho a aluminium alloy e be bonolo haholoanyane le ka potlako.
Thepa ea mochini le theknoloji ea khokahano ea li-alloys tsa aluminium
Ho nahanoa ka botlalo ka thepa ea mochini Le hoja lialloe tsa aluminium li na le modulus e tlase ea rekere, matla a tsona a khethehileng (karolelano ea matla ho boima) a bapisoa, kapa a betere ho feta tšepe ea matla a phahameng. Sena se bolela hore meaho ea alloy ea aluminium e ka ba bobebe ha e ntse e jara mojaro o tšoanang. Ka nako e ts'oanang, litšoaneleho tsa elastic deformation tsa li-alloys tsa aluminium li lokela ho nahanoa nakong ea moralo, 'me ho satalla le matla a sebopeho li lokela ho etsoa ka mokhoa o utloahalang ho netefatsa polokeho le botsitso ba sebopeho.
Boqapi le Nts'etsopele ea Litheknoloji tsa Khokahano
Li-alloys tsa aluminium li ka hokahana ka mekhoa e fapaneng, ho kenyeletsoa likhokahano tsa liboutu, likhokahano tsa rivet le likhokahano tse cheselitsoeng. E le ho fokotsa kutu ea galvanic, li-rivets kapa li-bolts tsa aluminium hangata li sebelisoa meahong ea alloy aluminium. Ka nako e ts'oanang, ka nts'etsopele ea theknoloji ea welding, ts'ebetso ea welding ea li-alloys tsa aluminium le eona e ntlafalitsoe haholo. MIG welding (melting inert gas welding) le TIG welding (tungsten inert gas welding) ke mekhoa e 'meli e sebelisoang ka tloaelo ea aluminium alloy welding e ka fanang ka manonyeletso a boleng bo phahameng a nang le lisebelisoa tse finyellang litekanyetso tse phahameng tsa ho haha borokho.
Ts'ebetso e tsitsitseng ea marokho a aluminium alloy
Lintlha tsa Moqapi bakeng sa Ts'ebetso e tsitsitseng
Likarolo tsa motsoako oa aluminium li ka 'na tsa hlokofatsoa ke ho kobeha ka morao le ho se tsitse ha torsional ha li kobeha, tse hlokang tlhokomelo e khethehileng nakong ea moralo. E le ho ntlafatsa botsitso ba sebopeho, baqapi ba ka nka mehato e sa tšoaneng, e kang ho eketsa litšehetso tse otlolohileng, ho fetola sebopeho sa sefapano, ho sebelisa li-stiffeners, joalo-joalo Mehato ena e ka ntlafatsa ka katleho botsitso ba sebaka le ka kakaretso ba marokho a aluminium alloy. le ho netefatsa polokeho ea sebopeho tlas'a meroalo e fapaneng.
Mehlala ea borokho ba aluminium alloy
Hangzhou Qingchun Road Middle River Borokho ba Pedestrian
Borokho bona bo sebelisa aluminium alloy truss structure girder, 'me thepa e ka sehloohong ea borokho ke 6082-T6 aluminium alloy. Borokho ba bolelele ba limithara tse 36.8 bo boima ba lithane tse 11 feela, bo bontšang melemo ea boqapi bo bobebe ba marokho a aluminium alloy. Moralo oa borokho ha o nahane feela ka ts'ebetso, empa o boetse o nahana ka botlalo ho lumellana le tikoloho e potolohileng, ho fetoha sebaka se setle sa toropo.
Shanghai Xujiahui Pedestrian Bridge
Borokho ba Shanghai Xujiahui ba tsamaeang ka maoto bo entsoeng ke Univesithi ea Tongji bo entsoe ka motsoako oa 6061-T6 oa aluminium, ka bolelele ba limithara tse 23, bophara ba limithara tse 6, boima bo shoeleng ba 150kN feela, le boima bo boholo ba boima ba 50t. Ho hahoa ka potlako le ho sebelisoa ha borokho bona ho bontša ts'ebetso le bokhoni ba marokho a alloy alloy metseng ea kajeno.
Beishi Xidan Pedestrian Bridge
The aluminium alloy superstructure ea Xidan Pedestrian Bridge e Bei City e hahiloe ke k'hamphani e tšehelitsoeng ka lichelete kantle ho naha, 'me profil ea mantlha ea aluminium ke 6082-T6. Kakaretso ea bolelele bo boholo ke 38.1m, bophara bo hlakileng ba borokho ke 8m, 'me bolelele bohle ke 84m. Borokho bona bo entsoe ho nahanoa ka boiketlo le polokeho ea batsamai. Ka nako e ts'oanang, tšebeliso ea lisebelisoa tsa aluminium alloy e boetse e fa borokho bophelo bo bolelele ba tšebeletso le litšenyehelo tse tlase tsa tlhokomelo.
Qetello
Tšebeliso ea lisebelisoa tse phahameng tsa aluminium alloy kahong ea borokho ha e ntlafatse feela ts'ebetso ea sebopeho le ho tšoarella ha marokho, empa hape e tlisa menyetla e mengata ea ho etsa borokho. Ka tsoelo-pele ea mahlale a thepa le nts'etsopele ea theknoloji ea kaho, marokho a aluminium alloy a lebelletsoe ho phetha karolo ea bohlokoa ho ahoeng ha borokho nakong e tlang mme e be sehokelo sa bohlokoa se hokahanyang litoropo tsa sejoale-joale.
