Ma waena o 500 ℃ a me 200 ℃, ua hoʻomau ka hana ʻana o ka moena hoʻokaʻawale wela 1.5mm-mānoanoa no 20 mau minuke me ka hoʻokuʻu ʻole ʻana i kekahi ʻala.
ʻO ka mea nui o kēia moena pale welaairgel, i kapa ʻia ʻo "ke aliʻi o ka insulation wela", i kapa ʻia ʻo "he mea hana hou e hiki ai ke hoʻololi i ka honua", ʻo ia ka manaʻo o ka honua i nā wahi palena palena. ʻO kēia huahana he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, pale wela kiʻekiʻe, ākea ka hoʻohana ʻana, hoʻohana nui ʻia i ka ʻoihana aerospace, nā mokulele a me nā moku, nā kaʻa kaʻa kiʻekiʻe, nā kaʻa ikehu hou, ka ʻoihana kūkulu hale a me ka ʻenehana pipeline insulation a me nā māla ʻē aʻe.
ʻEkolu kumu loiloi loiloi noairgeli loko o ka mākeke: pH kūpaʻa, hoʻomau i ka wela wela a me ka hydrophobicity mau. I kēia manawa, paʻa ka pH waiwai o nā huahana airgel i 7, ʻaʻole ia e corrosive i nā metala a i ʻole nā mea maka. Ma ke ʻano o ka waiwai adiabatic mau, ma hope o nā makahiki o ka hoʻohana ʻana, ʻaʻole e hoʻemi ʻia ka hana o ka huahana ma mua o 10%. No ka laʻana, i loko o ka 650 ℃ kiʻekiʻe wela kaiapuni, hoʻohana hoʻopau ʻole ʻia a puni ka makahiki, hiki ke lōʻihi i 20 mau makahiki. Hoʻomau ka hydrophobicity o 99.5%.
ʻO nā huahana Airgel, ka laulā o nā mea kumu, mai ka mea maʻamaumoena fiber aniani, Hoʻonui ʻia i ka basalt, silica kiʻekiʻe, alumina, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia ka huahana e hoʻopili i ka wela haʻahaʻa o ka minus 200 ° C LNG pipeline, hiki ke hoʻohana ʻia no ka hoʻomehana koke ʻana o ka ʻoi aku o hoʻokahi kaukani Celsius supersonic aircraft engine insulation, akā hiki ke hoʻohana ʻia i loko o nā kaiapuni.
Me ka piʻi nui ʻana o nā kaʻa ikehu hou, wehe ia i kahi no ka mākeke pad thermal. Me nā ʻāpana 126 wale nōairgel, hiki ke hana ʻia kahi moena palekana e pale ai i ka holo ʻana o ka wela a me ke ahi i loko o nā pila, e waiho ana i ka manawa kūpono no nā mea hoʻohana e pakele.
