Fa'asinomaga Sima Foam Aluminum Foam Ceramic Alumina Maualuluga Tete'e Su'ega Su'ega
Fa'amatalaga o oloa
Foam ceramics ua faia i porous sima foam tino, o loo i le precursor o uluai pores i le absorption o sima slurry e pei o se auivi, ina ua uma ona mago, fana ma avea, o le aveesea o le fausaga o fesootaiga tolu-dimensional o le organic precursor, ona o le fausia o se fua faatatau maualuga o pores tatala (80% ~ 90%). Laʻititi laʻititi (0.2 ~ 0.5g / cm3), faʻapitoa faʻapitoa tele, faʻaitiitia le mamafa, faʻatasi ai ma se fausaga fesoʻotaʻiga o le tino porous.

2, Ona o lona teteʻe vevela, le filogia, e le faigofie ona oona, tau maualalo ma isi tulaga lelei, ua faʻaaogaina lautele i le alamanuia vailaʻau ma isi fanua e feagai ma le faafitauli o
Ua fa'aaogaina lautele i le alamanuia vaila'au e feagai ai ma mea oona, malodorous ma isi kasa leaga.
3、O pupu ea tapuni i totonu o seramics foam faaitiitia le lelei exothermic ma le convection i le vevela propagation.
Convection, o loʻo i ai le maualalo o le vevela, faʻalavelave faʻafuaseʻi ma isi uiga sili ona lelei, o se mea e sili ona lelei le vevela.

Fa'avasegaina o Keramiki Foam
E masani lava ona fa'avasegaina sima foam i ni ituaiga se lua, e ta'ua o sela matala (reticulated) mea sima fa'apea fo'i mea sima sima tapuni, e fa'atatau i pores ta'ito'atasi o puipui mautu pe leai.
Fa'aaogāga o Fuga Keramiki
I le alumini alamanuia metallurgical, kopa ma isi alloys lafo, foam ceramics e mafai ona faaaogaina e avea o se mea faamama e faamama ese le oxidized ash slag. E mafai ona fa'aogaina ipu fa'amama sima foam i le oneone ma le u'amea, ma e mafai ona tu'u mafolafola pe tu.
