Mu 2015, zida zopangidwa ndi zitsulo zopangidwa ndi zitsulo zopangidwa ndi thovu zinapangidwa pamodzi ndi ofufuza ochokera ku DST ndi New York University Institute of Technology.

Ili ndi kachulukidwe ka 0.92 g/m3 yokha ndipo imatha kuyandama pamadzi. Chodabwitsa n'chakuti zinthuzi zimakhala ndi mphamvu zokwanira pamene zimalemera pang'ono, ndipo chipolopolo chake chimodzi chozungulira chimatha kupirira mphamvu ya mapaundi 25,000 pa inchi imodzi isanathyoke. Poyerekeza ndi thovu lachitsulo lachikhalidwe, ubwino wa chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo ndikuti kachulukidwe kake kakhoza kusinthidwa mkati mwamtundu wina, ndipo kukula ndi mawonekedwe a mabowo amatha kuwongoleredwa.

Metal Foam Porosity

Porosity imatanthawuza chiŵerengero cha kuchuluka kwa ma pores onse mu thupi la porous ku chiwerengero chonse cha thupi la porous, ndiko kuyeza kokhazikika kwa malo opanda kanthu a thupi lopweteka. The porosity wa zitsulo thovu zambiri amafika oposa 90%, ndipo ndi porous chitsulo ndi mphamvu zina ndi kulimba. Chitsulo chamtunduwu chimakhala ndi porosity yayikulu, ndipo pore awiri amatha kufika pamlingo wa millimeter.

Kuchuluka kwa thovu lachitsulo kumapangitsa kuti zinthu zachitsulo zikhale ndi ntchito zapadera. Mwachitsanzo, Zida zachitsulo zomwe zimagwiritsidwa ntchito popanga magalimoto, zimatha kuchepetsa kulemera kwagalimoto, kuwongolera mafuta, komanso kukulitsa chitetezo cha okwera pakagwa ngozi mothandizidwa ndi mphamvu zamayamwidwe abwino.

Popanga kwenikweni, zidapezeka kuti zida zambiri zamagalimoto zimatha kupangidwa ndi aluminiyamu ya thovu. Monga chivundikiro chapamwamba, chivundikiro cha pansi, mipando, mabampu, matabwa a kutsogolo ndi kumbuyo, ndi zina zotero. koma kulemera kwake ndi pafupifupi 25% kupepuka kuposa zigawo zachitsulo.

Reference: Mbiri yachitukuko cha thovu lachitsulo

Mu 1948, Sosnik anaganiza zokonza zitsulo zotayidwa zitsulo zotayidwa ndi vaporized mercury, zomwe zinakhala nthawi yoyamba kuti anthu akhale ndi lingaliro la thovu lachitsulo. Panthawiyi, izo zinathyola nthawi yaitali chiphunzitso chikhalidwe kuti zitsulo ndi wandiweyani dongosolo.

Mu 1951, Elliott anakwanitsa kupanga aluminiyamu ya thovu pogwiritsa ntchito njira yosungunula thovu.

Mu 1983, pepala lofalitsidwa ndi GJDVIES lidawonetsa chiyambi chovomerezeka cha kafukufuku wazitsulo zachitsulo, ndipo kufufuza kwa thovu lachitsulo kunayamba ndi nthawi yogwira ntchito.

Mu 1988, 《Porous Solids-structure & Properties》 lofalitsidwa ndi LJ Gbson & MF Ashby akadali ntchito yofunika kwambiri pa kafukufuku wa porous materials.

Mu 1991, Kyushu Industrial Research Institute of Japan yakhazikitsa njira zamafakitale zopangira aluminium thovu.

Mu 2000, Ashby ndi gulu lake poyamba anafotokoza mwachidule njira yokonzekera, kagwiridwe kake komanso kagwiritsidwe ntchito ka thovu lachitsulo.

Kuyambira 2000, luso lokonzekera la tinthu tating'ono tating'ono tating'ono tayamba kukula, ndipo gawo lofufuzira la thovu lachitsulo layambanso kukula mwachangu.
