Uhi ʻana o ka Aerogel
ʻO ke kumu o ka hana koʻikoʻi o nā uhi aerogel, ʻo ia ke ʻano microscopic kū hoʻokahi o kona ʻāpana koʻikoʻi - nano-aerogel. Hiki i kēia ʻano ke ālai pono i ʻekolu mau ala o ka hoʻoili wela: ka hoʻoili wela paʻa, ka hoʻoili wela convection ea, a me ka radiation thermal.
ʻOi aku ka maikaʻi o ka pale wela a me ka hopena mālama ikehu koʻikoʻi: ʻO kēia ka hana nui o nā uhi airgel. He haʻahaʻa loa ko lākou conductivity thermal, maʻamau mai 0.030 W/(m·K) a i ʻole, ʻoi aku ka haʻahaʻa ma mua o nā mea pale kuʻuna. ʻO ke ʻano kēia, hiki i kahi uhi lahilahi loa (e like me 2-3mm) ke hoʻokō i ka hopena pale e like me nā mea pale kuʻuna (e like me 30-40mm), e hōʻemi pono ana i ka nalowale o ka ikehu a me ka hoʻokō ʻana i ka mālama ikehu a me ka hoʻemi ʻana i ka hoʻohana ʻana.
Ke kūpaʻa ahi maikaʻi loa a me ka pale ʻana i ka lapalapa: Loaʻa i nā uhi Aerogel nā helu kūpaʻa ahi maikaʻi. Hiki i nā huahana he nui ke hōʻea i nā kūlana aupuni o ka pae A-level non-flamibility a i ʻole nā pae A2-level resistance, hiki ke hoʻopaneʻe pono i ka laha ʻana o ke ahi a hoʻomaikaʻi i ka palekana o nā mea i uhi ʻia.
Māmā ke kaumaha a me ka hoʻopili ikaika: ʻO Aerogel ponoʻī kekahi o nā "mea paʻa māmā loa" ma ka honua. No laila, ʻo ka uhi i hana ʻia ma hope o ka maloʻo ʻana o ka pena he haʻahaʻa ka mānoanoa a me ke kaumaha māmā, a ʻaʻole e kau i ke kaumaha nui ma luna o ka substrate. I ka manawa like, ma o ka hoʻonui ʻana i ka formula, kiʻekiʻe ka ikaika hoʻopili ma waena o ka uhi a me ka substrate e like me ka metala a me ka sima, a ʻaʻole maʻalahi ke hāʻule a haki paha.
Pale wai, pale wai a me ka pale ʻana i ka pala: He hydrophobic ka aerogel ponoʻī, e hiki ai i ka uhi ke loaʻa nā waiwai pale wai a me ka pale makū maikaʻi loa. Hiki iā ia ke pale pono i ka mahu wai mai ka hoʻopau ʻana i ka substrate a pale i ka condensation ma luna o ka ʻili o nā lako ʻoihana. Loaʻa i kekahi mau uhi nā hana pale-palaoa, hiki ke hoʻolōʻihi i ke ola lawelawe o nā lako.
ʻŌmaʻomaʻo a pili i ke kaiapuni, maʻalahi ke hoʻopili: ʻO nā uhi aerogel nui i loaʻa i kēia manawa he mau ʻōnaehana wai ka hapa nui, ʻaʻohe a he liʻiliʻi wale nō paha o nā hui organik volatile, ʻaʻohe mea ʻawahia a ʻaʻole hoʻopilikia i ke kaiapuni. He kūpono lākou no nā ʻano hana like ʻole e like me ka palaki ʻana, ka uhi ʻana i ka wili, a me ka pīpī ʻana, a he kūpono loa ia no ka hana ʻana i nā papa insulation seamless ma luna o nā ʻili o nā ʻāpana hana like ʻole e like me nā valves a me nā flanges.
Nā waiwai ʻē aʻe: Ma waho aʻe o nā ʻano i luna, loaʻa i nā uhi airgel nā pono e like me ka insulation leo a me ka hoʻemi ʻana i ka walaʻau, ke kūpaʻa ʻana i ka ʻelemakule, ke ola lawelawe lōʻihi, a me ke kūpaʻa wela maikaʻi i nā mahana kiʻekiʻe.
ʻO ka pale ʻana no nā paipu wela kiʻekiʻe, nā pahu mālama, nā ipu hoʻoneʻe, nā umu ʻoihana a me nā lako ʻē aʻe i nā ʻoihana e like me ka petrochemicals, ka mana, a me ka metallurgy;
Ka pale ʻana a me ka pale wela no nā paia o loko a me waho, nā kaupaku, a me nā papahele o nā hale, a no nā paia pale a me nā hale hana kila;
ʻO ka pale wela a me ka pale ʻana i ke ahi no nā ʻeke pila o nā kaʻa ikehu hou, e pale ana i ka laha ʻana o ka holo ʻana o ka pila; ʻO ka pale wela a me ka pale ʻana i ke ahi no nā ʻōnaehana halihali, nā moku, nā kaʻa i hoʻomoʻa ʻia, a pēlā aku;
Hoʻohana ʻia no ka hoʻomehana wela i nā lole ākea a me nā mokulele mokulele ma ke kahua aerospace; Nā uhi pale ahi no nā kaula; a me nā huahana waho hana kiʻekiʻe e kū mai ana (e like me nā lole pale anu, nā ʻeke moe, nā uhi kīʻaha insulated, a me nā mea ʻē aʻe)
