Iimpawu zeZakhiwo zeMathiriyeli ye-Aluminium Foam

Ugwebu lweAluminiyam yenziwe ngeintsimbi ye-aluminiyamizinto zematrix kunye neepores. Iiparamitha zesakhiwo se-aluminiyam ye-foam ibandakanya i-pore diameter, i-porosity okanye ukuxinana kwesalamane, ukujikeleza kwepore, kunye nommandla othile womphezulu. Ukudibanisa phakathi kwezakhiwo ze-pore zingahlelwa njenge-open-cell aluminium foam kunyei-aluminiyam i-foam evaliweyo, Ukuhanjiswa kwepore ye-foam ye-aluminium ngokuqhelekileyo i-random, kodwa iinkqubo ezithile zinokufezekisa ukuhanjiswa okucwangcisiweyo. Ubume bama-pores bunokuba yisakhiwo seseli evaliweyo, isakhiwo se-open-cell, okanye umxube wazo zombini. Imingxuma yei-open-cell aluminiyam ugwebuzixhunyiwe, ngelixa i-pores ye-foam ye-aluminium evaliweyo izimele kwaye ihlukaniswe omnye komnye ukuze i-foam ye-aluminium ithathwe njengento edibeneyo yezigaba ezibini: i-aluminium matrix kunye ne-pores. Ukwakhiwa kweeseli ezivaliweyo: iindonga ze-pore zivaliwe ngokupheleleyo komnye nomnye, kwaye igesi ifakwe kwi-pores, enesandi esihle kunye nemiphumo yokushisa ukushisa kwaye isetyenziswa ngokuqhelekileyo ekufakeni amandla, ukulwa nokungqubana, kunye nezinye iindawo. Isakhiwo se-Open-cell: iindonga ze-pore zixhunyiwe, kunye nokunyanzeliswa komoya kunye nokuhanjiswa kwamanzi, okufanelekileyo ukuhluzwa, ukuchithwa kobushushu kunye nezinye iimeko. Ekubeni iiparitha zesakhiwo se-aluminium foam zichaza ngokuthe ngqo ukusebenza kwe-foam ye-aluminium, kwizicelo eziphathekayo, izinto eziphathekayo ze-aluminium kunye neeparitha ezifanelekileyo kufuneka zikhethwe ngokwezicelo ezahlukeneyo. Xa kuthelekiswa nezixhobo zetsimbi zendabuko, i-aluminium i-foam ibonakala ngobukhulu obukhulu be-pore (ubungakanani bepore D = 0.2 mm ukuya kwi-8 mm), i-porosity ephezulu (i-porosity 63% ukuya kwi-90%), kunye noxinzelelo oluphantsi. Ulwakhiwo lwamathambo eugwebu aluminiyamibonisa ukuhanjiswa kwe-reticular ene-dimensional-dimensional, equka iindawo eziqinileyo ze-aluminium alloy. Le reticulation inika imathiriyeli iipropathi ezigqwesileyo zoomatshini, njengamandla athile aphezulu kunye nokufunxa kakuhle kwamandla. Umphandle wangaphandle we-aluminium foam udla ngokuba rhabaxa kunye neepores ezibonakalayo, kodwa umgangatho womphezulu unokuphuculwa ngokunyanga emva kokunyanga (umzekelo, ukugquma, umatshini).

Lilonke, iimpawu zesakhiwo se-aluminiyam i-foam yi-porosity yayo, ilula kunye namandla aphezulu, kunye ne-skeleton ye-dimensional reticulated skeleton. Ezi zakhiwo zesakhiwo zinquma ukusetyenziswa kwayo ngokubanzi kwiinkalo ze-acoustic kunye ne-thermal insulation, ukufunxa amandla, ukuchasana kwempembelelo, ukuhluza, kunye nokwakhiwa okulula.

Iimpawu zesakhiwo se-aluminiyam enogwebu: (a) i-aluminiyam enegwebu evulekileyo; (b) ialuminiyam enogwebu eneseli evaliweyo
