I loko o nā makahiki ʻelua i hala iho nei, i alakaʻi ʻia e ka hoʻomohala ʻenehana o nā mea palekana holo ka wela no nā ʻeke uila hou, koi nui nā mea kūʻai aku i ka hoʻonui ʻia ʻana o ka insulation thermal me ke kūpaʻa ablation like-ceramic-he waiwai nui no ka pale ʻana i ka hopena o ke ahi.
No ka laʻana, koi kekahi mau noi i nā wela wela o ka ʻaoʻao mua o 1200 ° C me ka mālama ʻana i nā wela ma hope ma lalo o 300 ° C. Ma nā mea aerospace, ʻo ka ʻaoʻao mua acetylene ablation ahi ma 3000°C koi i ka wela o ka ʻaoʻao hope ma lalo o 150°C. ʻOi aku ka paʻakikī o ka koi kiʻekiʻe no ka hoʻokō ʻana i ka hoʻokō ʻana i ka ceramicized silicone foam, ka mea e koi ai i ka hoʻonohonoho haʻahaʻa haʻahaʻa a me ka paʻa ʻana o ka insulation thermal maikaʻi loa i nā wela kiʻekiʻe. Hōʻike pū kēia mau mea i nā koi insulation wela hou no ka ʻenehana ceramicization.
Nā koi hana kūikawā (no ka ʻike wale nō):
E hoʻomehana i ka hāpana ma kahi paepae hoʻomehana e like me ka mea i hōʻike ʻia ma lalo nei. E mālama i ka ʻili wela ma 600 ± 25 °C no 10 mau minuke. E hoʻopili i kahi koʻikoʻi o 0.8 ± 0.05 MPa i ka mahana hoʻāʻo, e hōʻoia i ka noho ʻana o ka mahana o hope ma lalo o 200°C.
I kēia lā, hōʻuluʻulu mākou i kēia mau manaʻo no kāu kuhikuhi.
1. Synthetic Calcium Silicate - Thermal Insulation White Filler
Aia nā ʻano calcium silicate synthetic ma nā ʻano ʻelua: nā hale porous/spherical a me nā hale fibrous like me ka ceramic-fiber-like. ʻOiai nā ʻokoʻa o ka haku mele ʻana a me ka morphological, lawelawe nā mea ʻelua ma ke ʻano he mea hoʻopiha keʻokeʻo keʻokeʻo kūʻokoʻa kiʻekiʻe.
ʻO ka synthetic calcium silicate fiber he mea aloha kaiapuni amea palekana welame ka pale wela kiʻekiʻe a hiki i 1200-1260 ° C. Hiki ke hoʻohana ʻia ka pauka calcium silicate fiber synthetic i hana ʻia ma ke ʻano he mea hoʻoikaika ʻia i ka fiber no ka insulation kiʻekiʻe.
ʻO Synthetic porous a spherical calcium silicate, ʻo ia hoʻi, he keʻokeʻo kiʻekiʻe, maʻalahi o ka hoʻohui ʻana, kahi ʻano nanoporous waiwai, nā waiwai absorption ʻaila ultra-kiʻekiʻe (a hiki i 400 a ʻoi aku paha), a me ke kūʻokoʻa mai nā pōpō slag a i ʻole nā mea nui. Ua hōʻoiaʻiʻo i nā noi i loko o ka insulation kūpaʻa kiʻekiʻe a me nā panela ahi, e hōʻike ana i ka hiki ke hoʻohui ʻia i loko o ka ceramicized ablation-resistant material e hāʻawi i ka insulation kiʻekiʻe.
ʻO nā noi ʻē aʻe e pili ana: nā mea hoʻohui wai pauka, nā mea hoʻonaninani insulating kiʻekiʻe, nā mea lawe adsorbent meaʻala, nā mea anti-drip, nā mea hoʻoheheʻe paʻa paʻa, ka pahu silicone haʻahaʻa haʻahaʻa a me ka aila silicone decomposing ponoʻī, nā pepa hoʻopiha, etc.
2. Layered Porous Magnesium Aluminum Silicate– Hoʻokohu wela a me ka pale wela kiʻekiʻe
Pono kēia mineral silicate i ka calcination kiʻekiʻe me ka refractoriness a hiki i 1200 ° C. Hoʻokumu mua ʻia me ka magnesium aluminika silicate, e hōʻike ana i kahi ʻano porous layered waiwai e hāʻawi ana i ka ikaika hoʻopaʻa kiʻekiʻe, ke kūpaʻa wai maikaʻi loa, ka lōʻihi o ka refractory lōʻihi, a me ke kumukūʻai kiʻekiʻe.
ʻO kāna mau hana mua e pili ana i ka insulation wela kiʻekiʻe, ka hoʻohaʻahaʻa haʻahaʻa, hoʻonui i ka refractoriness, a me ka hoʻomaikaʻi ʻana i ka pale ablation a me ka insulation thermal no nā papa kalapona a me nā pahu. Hoʻopili ʻia nā mea noi i nā mea hoʻoheheʻe ceramicized, nā uhi pale ahi maikaʻi loa, nā mea hoʻoheheʻe refractory, a me nā mea hoʻoheheʻe wela ablation.
3. Nā Microspheres Ceramic - Ke kū'ē i ka wela kiʻekiʻe, ka wela wela, ka ikaika compressive
ʻO nā microspheres aniani puʻupuʻu he mea kānalua maikaʻi loa ia, akā ʻaʻole lawa kā lākou pale wela. ʻO ko lākou mau wahi palupalu ma ke ʻano he 650-800°C, me nā mahana hoʻoheheʻe ma 1200-1300°C. Hoʻopili kēia i kā lākou noi i nā hiʻohiʻona insulation thermal haʻahaʻa haʻahaʻa. Ma lalo o nā kūlana kiʻekiʻe e like me ka ceramicization a me ke kū'ē ablation, lilo lākou i mea ʻole.
ʻO kā mākou microspheres ceramic hollow e hoʻoponopono i kēia pilikia. Hoʻokumu mua ʻia me ka aluminosilicate, hāʻawi lākou i ke kūpaʻa wela kiʻekiʻe, ka insulation thermal koʻikoʻi, ka refractoriness kiʻekiʻe, a me ke kūpaʻa haʻihaʻi kiʻekiʻe. Hoʻopili nā noi i nā mea hoʻohui silikonika, nā mea hoʻoheheʻe refractory, nā mea hoʻohui wela kiʻekiʻe no nā resins organik, a me nā mea hoʻohui kiʻekiʻe. Hoʻopili nā ʻāpana koʻikoʻi i ka aerospace, ka ʻimi ʻana i ke kai hohonu, nā mea i hoʻohui ʻia, nā uhi, ka insulation refractory, ka ʻoihana ʻaila, a me nā mea insulation.
He mea maʻalahi loa kēia e hoʻohui ʻia (ʻaʻole like me nā microspheres aniani puʻupuʻu, pono e hoʻopuehu mua a hoʻololi paha no ka hoʻohui kūpono) a hōʻike i ke kūpaʻa maikaʻi loa. ʻO kona hiʻohiʻona ʻokoʻa, ʻo ia ka mea hāmama i ka ʻili i lana ʻole ma luna o ka wai, e maʻalahi ai ka mānoanoa a me ka noho ʻana.
Eia kekahi, ʻōlelo pōkole oairgel pauda—he mea hoʻoheheʻe silica porous synthetic. Ua ʻike nui ʻia ʻo Airgel ma ke ʻano he insulator thermal maikaʻi loa, loaʻa i nā ʻano hydrophobic/hydrophilic. ʻAe kēia i ke koho ʻana i nā ʻano lapaʻau kūpono e pili ana i nā substrates resin, e hoʻoponopono ana i nā pilikia o ka pauka airgel o ka hoʻopuehu ultra-māmā a hoʻomaikaʻi i kona dispersibility. Loaʻa nō hoʻi nā paʻi airgel e pili ana i ka wai no ka hoʻokomo pono ʻana i nā ʻōnaehana wai.
ʻO nā waiwai hoʻoheheʻe wela porous o ka pauka airgel hiki ke hoʻohana i kāna noi i: - Nā mea hoʻohui a me nā mea hoʻohui palaki - ʻO nā mea hoʻoheheʻe wela no nā pihi ikehu hou - Ke kūkulu ʻia ʻana o nā mea hoʻolalelale - ʻO nā ʻili lole pale wela - Ke kūkulu ʻana i nā paneli - Nā uhi hoʻoheheʻe wela ahi - Nā mea hoʻopili wela wela.
