Iindlela zokulungiselela kunye neengxaki ze-aluminium foam sandwich panels

Ulungiselelo lweiipaneli zesandwich ze-aluminiyamyahlulwe yangamacandelo amabini xa iyonke. Udidi lokuqala kukulungiselela i-foam ye-aluminium kuqala, kwaye emva koko udibanise i-foam ye-aluminium kunye nepaneli yensimbi ngeendlela ezahlukeneyo, ezifana nokudibanisa kwe-cemented, indlela yokutshiza i-thermal surface, kunye ne-welding connection. Uhlobo lwesibini kukulungiselela umzimba owenziwe ngaphambili wepaneli ye-aluminium foam sandwich, kwaye ke umzimba owenziweyo ushushu ukuze wenze i-foam engundoqo ye-foam, kwaye i-foam ipholile emva kokugqitywa kwe-foam eyipaneli ye-aluminium foam sandwich. Iindlela zokulungiselela ezisetyenziswa ngokuqhelekileyo ziquka ukucinezela okushushu - indlela yokwenza i-powder metallurgy foaming, ukuqengqeleka - ukugquma - indlela yokwenza amagwebu, njalo njalo.

1. Uqhagamshelo lweglu

I-Gluing ibhekisela kwindlela yokwenza iipaneli ze-sandwich ngokudibanisa i-foam ye-aluminium kwiipaneli zetsimbi ezine-adhesives ezifanelekileyo. Inkqubo ye-gluing ithatha uxhulumaniso lomzimba ukulungiselela ipaneli yesandwich, kwaye indlela ineenzuzo zenkqubo elula kunye nokuchaneka okuphezulu kwemveliso. Nangona kunjalo, ngenxa yeempawu zesakhiwo se-porosity ephezulu yeugwebu aluminiyam, ukukhutshwa kokungcola kwimingxuma ebusweni be-aluminium foam kunzima kakhulu; kule ndlela yokudibanisa, iphaneli kunye noluhlu oluphambili lugxininiswe kakhulu kwi-aperture prongs, kwaye indawo yokubambisana esebenzayo incinci, ebangela ukuba amandla okubambisana aphantsi kwesakhiwo sesandwich; i-adhesive ihluleka kwiqondo lokushisa eliphezulu okanye kwiindawo ezinqabileyo ezinqabileyo, ezibangela ukuhlukana koluhlu oluphambili kwipaneli kunye nokutshatyalaliswa kwesakhiwo.

2. Uxhulumaniso lwe-Welding

Iindlela ze-welding zokulungiselela i-foam aluminium sandwich panels ziquka i-laser beam welding, i-ultrasonic torsion welding, kunye ne-brazing connections. I-laser beam welding kukusetyenziswa kwamandla aphezulu e-laser ashushu kwiphaneli kunye ne-foam aluminiyam umphezulu umaleko ukunyibilika, ukupholisa emva kokudibanisa ezimbini kunye, indawo ye-welding, kunye nolandelelwano lwe-welding eboniswe kuMfanekiso 1. lawula indawo edibeneyo edibeneyo. Nangona le ndlela inokwenza umsebenzi oqhubekayo, ukusebenza kakuhle kuphantsi, kwaye amandla ebhondi yemveliso nawo aphantsi. Umgaqo we-ultrasonic torsion welding kukudibanisa izinto ezimbini kunye namandla e-ultrasonic. Nangona kunjalo, le ndlela idinga indawo ethile ye-welding, kwaye akunakwenzeka ukugqiba i-welding yazo zonke iindawo ezijoliswe kuyo, ezithintela ukusetyenziswa kwale ndlela kwimveliso yangempela. Uqhagamshelo lokuqhafaza luya kuthintelwa ngumaleko oxidized we-aluminium ye-foam, ngoko ke kubalulekile ukususa umaleko oxidized, kwaye xa usebenzisa itekhnoloji yokubrawuza ngaphandle kwe-brazing flux in.aluminiyam yogwebuiipaneli zesandwich, amanye amanyathelo okulwa nokubola kufuneka athathelwe ingqalelo ukukhusela i-zinc-based kunye nezinye i-alloys ekudibaniseni kunye ne-aluminium corrosion. Ukongezelela, iinxalenye ezidityaniswe yile ndlela zinemingxuma kuphela, ngoko ke amandla okudibanisa aya kuncitshiswa.

3. Indlela yokutshiza nge-thermal ebusweni

Inkqubo yokwaleka ngokuqhelekileyo ifuna iqondo eliphezulu lokucama phezu komhlaba wecandelo, ngoko ke indlela ayifanelekanga kwizakhiwo ezinzima. Ukutshiza nge-Thermal kungobobuchwephesha bomphezulu, obubonwa ngeengcingo ezinyibilikayo okanye umgubo. Le ndlela isebenzisa ijethi yomoya ukukhawulezisa izinto ezinyibilikisiweyo kwaye idluliselwe kumphezulu wecandelo eliza kugqunywa, livumela ukusetyenzwa kwamacandelo anemilo enzima. Kule ndlela, umthombo wobushushu ngokuqhelekileyo i-arc yombane. Nangona kunjalo, le ndlela inzima ukwenza ishishini ngenxa yobunzima benkqubo.

4. Ukucinezela okushushu - indlela yokwenza umgubo we-metallurgy

Ngale ndlela, i-core powder powder esetyenziselwa ukukhupha amagwebu kuqala ibekwe kwiphaneli, kwaye emva koko ifakwe kwi-mold kunye, kwaye i-hydraulic press isetyenziselwa ukufaka uxinzelelo olubandayo kubo, emva koko izikhewu zibanjwe kwi-450 ℃ malunga neyure enye kwaye emva koko ucinezele ubushushu ukufumana izikhewu ezingenanto ezinokusetyenziselwa ukuphuphuma ugwebu. I-preform ke ishushu kwaye ifakwe amagwebu kwi-mold evaliweyo, kwaye ipaneli yesandwich ifunyenwe emva kokupholisa. Ubukho besikhunta kule ndlela buya kuba nemida ethile kubungakanani bepaneli yesandwich ye-aluminium egqityiweyo.

5. Indlela yokuqengqeleka-i-coating-foaming

Le ndlela ngumgubo woqobo wokugquma amagwebu kusetyenziswa iindlela ezifanelekileyo zokuqengqeleka ukwenza izinto ezingundoqo, emva kokuba ipaneli kunye nezinto ezingundoqo ezilungiselelwe ukuqengqeleka, ukwambathisa, ukufumana izikhewu ezenziwe ngaphambili, zigwebu emva kokupholisa ukufumana isakhiwo esihle sesandwich. Iphaneli. Le ndlela yokulungiswa kweemveliso ezinamandla amakhulu okudibanisa inokuqonda imveliso eqhubekayo kodwa idinga ukunqoba ubunzima obubini bezobugcisa: enye imfuno yokuxinanisa umgubo, kwaye okwesibini kukudibanisa okusebenzayo kwezinto eziphambili kunye ne-panel rolling.
