Ubwino ndi Makhalidwe a Aluminium Foam

Kupititsa patsogolo luso lamakono lamakono lachititsa kuti pakhale kuwonjezereka kwa luso lokonzekera zitsulo za thovu ndi kuchepetsa kosalekeza kwa mtengo wopangira. Chithovu chitsulo choimiridwa ndialuminium thovundi mtundu watsopano wazinthu zogwirira ntchito zomwe zapangidwa mwachangu m'zaka zaposachedwa. Monga zinthu zomangika, zimadziwika ndi kulemera kopepuka komanso mphamvu zapadera. Monga zinthu zogwirira ntchito, chithovu cha aluminiyamu chimakhala ndi zabwino zoyamwa modzidzimutsa, kugwedezeka kwamphamvu, kukana kutentha kwambiri, kutsekereza mawu komanso kuyamwa kwamawu.

The mkati pores wachithovu cha aluminiyamu chotsekedwaamadzazidwa ndi mpweya umene uli ndi mphamvu yaing'ono yotengera kutentha, zomwe zimapangitsa kuti kutentha kwake kukhale kochepa kwambiri kuposa zipangizo zolimba. Dera lalikulu lapadera, porosity yayikulu, malo otenthetsera ambiri komanso kutentha kwambiri kwa khoma la pore la aluminiyamu ya cell foam kumapangitsa kusinthana kwabwino kwa kutentha. Pansi pa kayendedwe kachilengedwe, kusinthana kwa kutentha kumatha kuchitika kudzera mukuyenda kwa gasi kapena madzi mu pores a zitsulo za thovu monga kupyolera mu dzenje thovu la aluminiyamu ndi khoma lake la pore, kotero kuti kudzera mu dzenje la aluminium thovu ndi njira yabwino kwambiri yosinthira kutentha. zakuthupi kapena zotayira kutentha.

Aluminiyamu thovu mu psinjika ndondomeko adzakhala n'kukhala ambiri ntchito mu mawonekedwe a zotayidwa thovu selo mapindikidwe, kugwa, kuphulika ndi kukangana ndi mitundu ina ya kutayika mphamvu, kotero chithovu akhoza kuyamwa chiwerengero chachikulu cha mphamvu kunja mphamvu.Chithovu cha Aluminiumali ndi mawonekedwe otsika kwambiri, zitsulo zotayidwa bwino za aluminiyumu zotayira zimakhala pafupifupi nthawi 5 mpaka 10 kuposa za aluminiyumu. Pogwiritsa ntchito mayamwidwe abwino amphamvu komanso kunyowetsa kwa thovu la aluminiyamu, imatha kupangidwa kukhala zida zabwino kwambiri zoyamwitsa mphamvu ndi zida zothimbirira, monga ma bumpers agalimoto, zida zoyatsira ndege, zikepe, ziwiya zodzitetezera ndi chopukusira chotchinga chothamanga kwambiri. .

Chifukwa zabwino madzimadzi kufala mphamvu, kutentha dissipation ntchito ya kudzera-dzenje thovu zitsulo akhoza kufika madutsidwe matenthedwe wandiweyani matrix, ndi kugwiritsa ntchito zitsulo thovu akhoza kumapangitsanso kutentha kuwombola mphamvu exchangers kutentha kwa zipangizo zakuthambo, masinki otentha otentha opangira mphamvu zamagetsi, ndi nsanja zolumikizira mpweya kuti uzizizire. Mwachitsanzo, pazida zotsutsana ndi kuzizira ndi kuzizira zomwe zimagwiritsidwa ntchito pa ndege,mapanelo a aluminium thovu odutsa m'bowoamaikidwa kutsogolo kwa mapiko, ndipo mpweya wotentha kapena antifreeze ukhoza kupopera kuchokera pazitsulo za aluminiyumu za thovu kuti akwaniritse cholinga chotsutsa-icing.
