Izindlela zokulungiselela kanye nezinkinga zamapaneli e-aluminium foam sandwich

Ukulungiswa kweamapaneli e-aluminium foam sandwichihlukaniswe izigaba ezimbili sezizonke. Isigaba sokuqala ukulungisa igwebu le-aluminium kuqala, bese uxhuma igwebu le-aluminium nephaneli yensimbi ngezindlela ezihlukene, njengoxhumano lukasimende, indlela yokufafaza okushisayo, nokuxhumeka kwe-welding. Uhlobo lwesibili ukulungisa umzimba owenziwe ngaphambili wephaneli yesamishi le-aluminium foam, bese umzimba owenziwe ngaphambilini ushiswa ukuze wenze ungqimba oluyisisekelo lube igwebu, futhi igwebu liyapholiswa ngemva kokuphothulwa kwegwebu eliyiphaneli yesamishi le-aluminium foam. Izindlela zokulungiselela ezivame ukusetshenziswa zihlanganisa ukucindezela okushisayo - indlela ye-powder metallurgy foaming, rolling - coating - foaming method, njalonjalo.

1. Uxhumano olunamanzi

I-Gluing ibhekisela endleleni yokwenza amaphaneli amasemishi ngokuhlanganisa igwebu le-aluminium kumaphaneli ensimbi anezinamathiselo ezifanele. Inqubo ye-gluing yamukela ukuxhumana ngokomzimba ukuze kulungiswe iphaneli yesangweji, futhi indlela inezinzuzo zenqubo elula kanye nokunemba okuphezulu kokukhiqiza. Kodwa-ke, ngenxa yezimpawu zesakhiwo se-porosity ephezulu yei-aluminium foam, ukukhishwa kokungcola emigodini ebusweni be-aluminium foam kunzima kakhulu; kule ndlela yokuxhuma, iphaneli kanye nesendlalelo esiyinhloko kugxilwe ngokuyinhloko kuma-aperture prongs, futhi indawo yangempela yokubopha ephumelelayo incane, okuholela ekuqineni okuphansi kokubopha kwesakhiwo se-sandwich; i-adhesive ihluleka emazingeni okushisa aphezulu noma ezindaweni eziqinile ezonakalisayo, okubangela ukuhlukaniswa kwesendlalelo esiyinhloko kusuka kuphaneli kanye nokubhujiswa kwesakhiwo.

2. Ukuxhumana kwe-Welding

Izindlela zokushisela zokulungiselela amaphaneli e-foam aluminium sandwich zifaka i-laser beam welding, i-ultrasonic torsion welding, nokuxhumeka kwe-brazing. I-laser beam welding iwukusetshenziswa kwamandla aphezulu ashisayo e-laser ekuphanelini nasekuncibilikeni kongqimba lwe-aluminium eyigwebu, ukupholisa ngemva kwenhlanganisela yezinto ezimbili ndawonye, ​​indawo yokushisela, nokulandelana kokushisela okuboniswe kuMfanekiso 1. Ukushisela kwe-laser kunembe kakhulu futhi kungenza ngempumelelo lawula indawo ehlangene encibilikile. Nakuba le ndlela ingenza umsebenzi oqhubekayo, ukusebenza kahle kuphansi, namandla ebhondi yomkhiqizo nawo aphansi. Umgomo we-ultrasonic torsion welding ukuhlanganisa izinto ezimbili ndawonye ngamandla e-ultrasonic. Kodwa-ke, le ndlela idinga indawo ethile yokushisela, futhi akunakwenzeka ukuqedela ukushisela kwazo zonke izindawo ezihlosiwe, okuvimbela ukusetshenziswa kwale ndlela ekukhiqizeni kwangempela. Uxhumano lwe-brazing luzovinjelwa ungqimba oluyi-oxidized lwe-aluminium ye-foam, ngakho-ke kubalulekile ukususa isendlalelo esixutshwe ne-oxidized, futhi uma usebenzisa ubuchwepheshe bokubhula ngaphandle kwe-brazing flux in.i-aluminium foamama-sandwich panel, ezinye izinyathelo zokulwa nokugqwala kufanele zicatshangelwe ukuze kuvinjelwe i-zinc-based kanye namanye ama-alloys ekuhlanganisweni nokugqwala kwe-aluminium. Ngaphezu kwalokho, izingxenye ezixhunywe ngale ndlela zinezimbobo zembobo kuphela, ngakho amandla esibopho azoncishiswa.

3. Indlela yokufafaza eshisayo ebusweni

Inqubo yokumboza ngokuvamile idinga izinga eliphezulu lokugcwala ebusweni bengxenye, ngakho-ke indlela ayifanele izakhiwo eziyinkimbinkimbi. Ukufafaza okushisayo kungokwezobuchwepheshe obungaphezulu, obubonakala ngezintambo ezincibilikayo noma izimpushana. Le ndlela isebenzisa indiza yomoya ukusheshisa into encibilikisiwe futhi iyidlulisele ebusweni bengxenye ezogcotshwa, okuvumela ukucutshungulwa kwezingxenye ezinobumo obuyinkimbinkimbi. Ngale ndlela, umthombo wokushisa ngokuvamile uyi-arc kagesi. Nokho, le ndlela inzima ukwenza izimboni ngenxa yobunkimbinkimbi benqubo.

4. Ukucindezela okushisayo - indlela ye-powder metallurgy foaming

Ngale ndlela, i-core layer powder esetshenziselwa ukwenza amagwebu ifakwa kuqala kuphaneli, bese ihlanganiswa ndawonye, ​​bese kusetshenziswa umshini wokucindezela obandayo, emva kwalokho izikhala zibanjwe ku-450 ℃ cishe ihora elingu-1 bese kucindezelwa ngokushisa ukuze kutholwe izikhala ezifakwe ngaphambili ezingasetshenzwa ukuze kukhihlize amagwebu. Khona-ke i-preform iyashiswa futhi ifakwe amagwebu esikhunjeni esivaliwe, futhi iphaneli yesangweji itholakala ngemva kokupholisa. Ukuba khona kwesikhunta kule ndlela kuzoba nemikhawulo ethile kusayizi wephaneli yesangweji ye-aluminium foam eqediwe.

5. Indlela yokugoqa-enamagwebu

Le ndlela iyimpushana yasekuqaleni yokugwaza igwebu kusetshenziswa izindlela ezifanele zokugoqa ukwenza izinto eziwumgogodla, ngemuva kwephaneli kanye nezinto eziwumgogodla ezenziwe ngaphambili zokugoqa, ukugqoka, ukuthola izikhala ezakhiwe ngaphambilini, zigwebu ngemuva kokupholisa ukuze uthole isakhiwo esihle sesemishi. iphaneli. Le ndlela yokulungiswa kwemikhiqizo enamandla amakhulu okubopha ingakwazi ukubona ukukhiqizwa okuqhubekayo kodwa idinga ukunqoba ubunzima obubili bobuchwepheshe: enye iyisidingo sokugxilisa impushana, kanti okwesibili inhlanganisela ephumelelayo yezinto eziyinhloko kanye ne-panel rolling.
