Kumzi-mveliso weemoto, i-aluminiyam igwebu isetyenziselwa ikakhulu ukuxhathisa ukothuka komzimba wemoto kunye nokunciphisa ingxolo kunye nokufakwa kobushushu bomzimba wemoto kunye neendonga zokwahlula.
Nge-cell-foam yensimbi yinto ephuculwe ngokukodwa ephezulu-ukungena kwamanzi kunye nesakhiwo se-sponge esifana ne-porous esivela ngaphakathi. Ukungena kwesandi ukusuka kumphezulu ukuya ngaphakathi kwayo kubangela ukuba imicu encinci yomoya kunye nezinto ezikwiipores zingcangcazele, kwaye ngokukhuhlana kunye nokumelana ne-viscous, amandla omsindo aguqulwa abe ngamandla obushushu kwaye afunxe.

Xa kuthelekiswa nezinye izinto ezifunxa isandi, izixhobo zetsimbi ezinegwebu zineempawu eziphezulu zokufunxa isandi kuluhlu oluphantsi lokujikeleza. Ngokokhetho lobunzima bomaleko womoya, lubonisa umphumo ogqwesileyo wokufunxa isandi xa ubandakanya uluhlu olubanzi lwamasimi asezantsi-frequency.
Isetyenziselwa ukufunxa isandi semoto kunye namagumbi kaloliwe, ayipheleli nje ngokuba nesandi esihle sokufunxa isandi, kodwa ikwanentsebenzo engcono yokuchasana noguquko kunezixhobo zepolyester zemveli, inokusebenza okuhle kokufunxa amandla, amandla aphezulu, ukungatsha kunye nokwandisa ukhuseleko. zezixhobo zothutho; Ngelo xesha, izinto zetsimbi azikho inetyhefu kwaye zingenabungozi, ezihambelana ngakumbi nemigangatho yokukhusela indalo.
Okwangoku, izixhobo zesinyithi ezinogwebu zisetyenziswe ngokubanzi kwizixhobo zokugquma isandi kwiimoto kunye neemoto zololiwe kumazwe angaphandle.
