Kuchepa kwa mafuta opangira mafuta komanso nkhawa zomwe zikukulirakulira pazamphamvu komanso zachilengedwe zapangitsa kuti pakhale kafukufuku wambiri wofuna kupanga njira zina zamagetsi. Electrochemical electrolysis of water imatengedwa ngati njira yodalirika yopangira mafuta a haidrojeni.

M'nthawi yakuchulukirachulukira kwamalumikizidwe opanda zingwe komanso kuyipitsidwa kwamagetsi, kufunikira kwa zida zogwiritsa ntchito mafunde amagetsi kwakhala kofunika kwambiri kuposa kale. Chithovu chachitsulo, monga chinthu chatsopano, chikuwonetsa kuthekera kwakukulu pantchito iyi. Kafukufuku waposachedwa wayang'ana kwambiri pakuwunika mphamvu yamagetsi yamagetsi yamagetsi azitsulo zachitsulo, ndipo zotsatira zake ndi zodabwitsa.

M'dera lamakono, timafunsira zotchinga zomveka bwino, zokambirana, zipatala, masukulu, maofesi oyang'anira misewu, ndi zina zotero kufunikira kwa kuchepetsa phokoso, pokambirana, funso lofunsidwa kwambiri ndilo: zambiri izi zitha kuchepetsedwa. Tsopano tikugawana nanu mfundo yochepetsera phokoso la zotchinga zomveka.

Chithovu cha Aluminium ndi chinthu chopepuka chopepuka, chomwe chimagwiritsidwa ntchito kwambiri popanga magalimoto, kukongoletsa nyumba ndi magawo ena. Kuti mupange chithovu cha aluminium, muyenera kugwiritsa ntchito zida zingapo, kuphatikiza kukonza, thovu, kuyanika ndi njira zina. Mukamagwiritsa ntchito zidazi, samalani zachitetezo, sinthani ndikusunga zidazo molingana ndi malangizo kuti muwonetsetse kuti chithovu cha aluminiyamu chimapangidwa komanso kugwira ntchito moyenera.

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 ntchito iyi, 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 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.

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?

Kodi mumadziwa thovu la aluminiyamu? Zinthu zatsopanozi zikuyambitsa chipwirikiti m'mafakitale osiyanasiyana chifukwa cha kupepuka kwake komanso kusinthasintha. Mu blog iyi, tiwona bwino mitundu yosiyanasiyana ya thovu la aluminiyamu ndikuwunika momwe amagwiritsira ntchito.
