Sezvatinoziva tese, zvinhu zvakaita sesiponji, purasitiki yakapushwa, rabha uye huni zvinowanzosarudzwa senge cushioning uye anti-kudhumhana zvinhu muhupenyu chaihwo. Seimwe yemidziyo ine porous simbi, ndezvipi zvakanakira kunyudza kwayo simba uye kubhafa?

Mukutaura kwe layman, yega yega-inotora simba uye inovharira zvinhu ine yayo yepamusoro inotakura-inotakura peak kukosha. Mushure mekunge nzvimbo yeyuniti yadarika imwe dzvinyiriro, simba-rinotora uye bhafa rinorasika. Naizvozvo, masiponji, mapurasitiki ane furo, rabha, furo aruminiyamu, etc. Kudzvanywa siyana pari zvino ndiyo yakanakisa uye inonyanya kushandiswa simba-kunopinza bhafa zvinhu.

Sechinhu chesimbi chine chiedza chekupedzisira chinogona kuyangarara pamusoro pemvura, furo realuminium rine density ye 0.2-0.4g/cm³, inenge 1/30 ye density yesimbi; zvisinei, kuomarara kwayo kupeta 1.5 nguva yesimbi; pasi pehuremu hwakafanana, Simba rekumanikidza inguva 5 iyo yesimbi; panguva imwe chete, kunyorovesa kwealuminium yakapushwa kakapetwa ka5-10 kune yesimbi, uye aruminiyamu yakapupuma ine porosity inodarika 80% inogona kutora 20J/cm³ yesimba kana yakaremara ne50%, inova ndiyo yakanyanya kunaka. . Zvinhu zvinokatyamadza.
