Chithovu cha aluminiyamu ndi chofanana ndi mawonekedwe a siponji ndipo chimadziwika ngati chitsulo chapadziko lonse lapansi, chokhala ndi kachulukidwe kakang'ono komanso kulemera kopepuka, komwe kumagwiritsidwa ntchito ngati chotchinga choteteza magalimoto apamlengalenga, chosagwirizana ndi kuponderezedwa ndikutha kupirira mphamvu zamagetsi zomwe zimayambitsidwa ndi ma radiation. Ndi chitsulo chatsopano chopangidwa ndi thovu la aluminiyamu aloyi.

Monga zida zodzitetezera zomwe zimagwiritsidwa ntchito kwambiri, kugwiritsa ntchito masangweji a aluminium foam sandwich (AFS) kumakhalabe kokakamizika ndi kutsika kwamakina kwapakatikati pa thovu. Kuphatikizika kwa ma coppercoated carbon fibers (Cf) kwatsimikizira kukhala kothandiza pakuwongolera makina a thovu la aluminiyamu.

Komabe, kumvetsetsa za kutuluka kwa thovu ndi microstructure akadali ochepa. Mu ntchitoyi, AFS ndi CF/AFS zidapangidwa ndi njira yolongedza zitsulo. Khalidwe lochita thobvu la AFS ndi Cf/AFS pa kutentha kokwezeka lidawonedwa pogwiritsa ntchito ukadaulo wa synchrotron radiation X-ray imaging kuti afufuze momwe Cf imakhudzira kuphulika kwa nucleation, kukula, ndi kukhazikika kwa thovu. Kuphatikiza apo, kugawa kwa kukula kwa pore, microscopic microstructure, ndi compressive mechanical properties za AFS ndi Cf/AFS zinawunikidwa. Zotsatira zake zidawonetsa kuti kukhalapo kwa CF kumawonjezera kuchuluka kwa ma nucleation, kumapangitsa kuti thovu likhale lokhazikika, komanso limalepheretsa kupangika kwa thovu lalikulu lodziwika bwino panthawi yoyambira ma nucleation ndi kukula. Pakadali pano, Cf/AFS idawonetsa ma diameter ang'onoang'ono a pore ndi zolakwika zochepa kuposa AFS. Kugawidwa kwa Cf ndi kunyowa kwabwino kwambiri pakhoma la pore kumalepheretsa kuphulika kwa filimu yamadzimadzi komanso kuchepa kwa coalescence. Kuyesera kwapang'onopang'ono kunasonyeza kuti, poyerekeza ndi AFS, mphamvu yowonongeka ndi mphamvu ya Cf / AFS yawonjezeka ndi pafupifupi 40.6% ndi 84.8%, motero.

Aluminium thovu masangweji masangweji akuchulukirachulukirachulukira m'mafakitale osiyanasiyana chifukwa cha mawonekedwe awo apadera komanso osiyanasiyana ntchito. Mapanelowa amakhala ndi zinthu zopepuka (monga chithovu cha aluminiyamu) zomangidwa pakati pa mapepala owonda a aluminiyamu. Kumanga kwatsopano kumeneku kumapangitsa kuti zinthuzo zikhale zopepuka, komanso zamphamvu, zolimba komanso zolimbana ndi dzimbiri. Mu blog iyi, tiwona bwino ntchito ndi phindu la mapanelo a masangweji a aluminiyamu, komanso momwe amakhudzira mafakitale osiyanasiyana.

Pakalipano, mapangidwe abwino kwambiri ndi kuchepetsa kulemera kwa thupi popanda kuchepetsa ntchito ya thupi, muzochitika zina kuti apeze njira yabwino yosinthira katunduyo, kuti apange mawonekedwe abwino a thupi; Panthawi imodzimodziyo, chiwerengero chachikulu cha zipangizo zatsopano ndi matekinoloje atsopano amathandizanso kuchepetsa kulemera kwa thupi, ndiye, zotsatirazi pamodzi kumvetsetsa ubwino ndi kuipa kwa zipangizo wamba opepuka izo!

Chithovu chachitsulo chikukula kwambiri m'mafakitale osiyanasiyana chifukwa chopepuka komanso champhamvu kwambiri. China Beihai Composites Co., Ltd. ndi m'modzi mwa omwe amapanga thovu lachitsulo ndipo kampaniyo ili patsogolo popanga zida zatsopano zogwirira ntchito zosiyanasiyana.

Chithovu chachitsulo ndi chitsulo chokhala ndi zinthu zapadera, zomwe zimakhala ndi zitsulo komanso zitsulo, choncho dzina lakuti chitsulo chithovu. Kotero, kodi thovu lachitsulo ndi chitsulo?

Chithovu chachitsulo chikukula kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso ntchito zake. Chimodzi mwazinthu zazikulu za thovu lachitsulo ndi porosity yake, yomwe imagwira ntchito yofunika kwambiri pakuzindikira zomwe zili ndi zinthu zomwe zimayenera kugwiritsidwa ntchito mosiyanasiyana. Mu blog iyi, tiyang'ana mozama za lingaliro la porosity muzitsulo zachitsulo ndikuwona zomwe zikutanthawuza mu ntchito zosiyanasiyana.

Foam yamkuwa ikupanga mafunde muukadaulo wa batri chifukwa cha mawonekedwe ake apadera. Amadziwika ndi malo ake okwera kwambiri komanso matenthedwe abwino kwambiri komanso magetsi, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakugwiritsa ntchito batri. Komabe, padakali chisokonezo chokhudza ma conductive ake komanso ngati ndi chinthu choyenera kugwiritsidwa ntchito m'mabatire. Mubulogu iyi, tiwona momwe chithovu chamkuwa chimagwirira ntchito komanso zomwe zingagwire ntchito muukadaulo wa batri wamtsogolo.

Aluminiyamu thovu ndi chinthu chochititsa chidwi chomwe chikukula kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera komanso mapindu osiyanasiyana. Kuchokera pakukhala opepuka komanso olimba mpaka kutenthetsa kwambiri komanso kutsekereza kwamayimbidwe, chithovu cha aluminiyamu chatsimikizira kukhala chinthu chofunikira pamagwiritsidwe ambiri. M'nkhaniyi, tiwona ubwino wa thovu la aluminiyamu ndi momwe lingasinthire momwe timapangira ndi kupanga zinthu zosiyanasiyana.

Chimodzi mwazinthu zofunika kwambiri zozungulira chithovu chamkuwa ndi ma conductivity ake, zinthu zosunthika komanso zosunthika. Mu blog iyi, tiwona momwe thovu lamkuwa limagwirira ntchito, mawonekedwe ake, ndi ntchito zake zosiyanasiyana.
