I nā makahiki ʻelua i hala iho nei, i hoʻokele ʻia e ka ulu ʻana o ka ʻenehana o nā mea pale wela no nā pila ikehu hou, ke koi nui nei nā mea kūʻai aku i ka hana insulation thermal i hoʻonui ʻia me ke kū'ē ʻana i ka ablation e like me ka ceramic—kahi waiwai nui no ke kū ʻana i ka hopena lapalapa.
No ka laʻana, koi kekahi mau noi i nā mahana ablation lapalapa mua o 1200°C me ka mālama ʻana i nā mahana hope ma lalo o 300°C. I nā mea aerospace, koi ka ablation lapalapa acetylene mua ma 3000°C i nā mahana hope ma lalo o 150°C. ʻO ka paʻakikī loa ka hoʻonui ʻia ʻana o ke koi no ka hana compression i loko o ka huʻa silicone ceramicized, kahi e koi ai i ka hoʻonohonoho compression haʻahaʻa a me ka paʻa ʻana o ka insulation thermal maikaʻi loa i nā mahana kiʻekiʻe. Hōʻike pū kēia mau mea i nā koi insulation thermal hou no ka ʻenehana ceramicization.
Nā koi hana kikoʻī (no ka ʻike wale nō):
E hoʻomehana i ka hāpana ma luna o kahi kahua 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 kau i kahi kaumaha o 0.8 ± 0.05 MPa ma ka mahana hoʻāʻo, e hōʻoia ana e noho mau ana ka mahana o ka ʻili hope ma lalo o 200 °C.
I kēia lā, ke hōʻuluʻulu nei mākou i kēia mau manaʻo no kāu ʻike.
1. Kalima Silicate Hana ʻia - Hoʻopiha Keʻokeʻo Hoʻopaʻa Mahana
Aia ka silicate calcium synthetic i ʻelua ʻano: nā ʻano porous/spherical a me nā ʻano fibrous e like me ka ceramic-fiber. ʻOiai nā ʻokoʻa o ka haku mele a me ke ʻano, lawelawe nā mea ʻelua ma ke ʻano he mau mea hoʻopihapiha keʻokeʻo pale wela kiʻekiʻe.
He mea aloha kaiapuni ka fiber calcium silicate synthetic amea hoʻopaʻa wela palekaname ke kūpaʻa wela kiʻekiʻe a hiki i 1200-1260°C. Hiki i ka pauka fiber silicate calcium synthetic i hana kūikawā ʻia ke lawelawe ma ke ʻano he mea i hoʻoikaika ʻia i ka fiber no ka pale ʻana i ka wela kiʻekiʻe.
ʻO ka calcium silicate porous a spherical paha, ʻoiai, he keʻokeʻo kiʻekiʻe, maʻalahi o ka hoʻohui ʻana, kahi ʻano nanoporous waiwai, nā waiwai omo ʻaila kiʻekiʻe loa (a hiki i ka 400 a ʻoi aku paha), a me ke kūʻokoʻa mai nā pōpō slag a i ʻole nā ʻāpana nui. Ua hōʻoia ʻia nā noi i loko o ka insulation pale wela kiʻekiʻe a me nā panela pale ahi, e hōʻike ana i ka hiki ke hoʻokomo ʻia i loko o nā mea pale ablation ceramicized e hāʻawi i ka insulation wela kiʻekiʻe.
ʻO nā noi ʻē aʻe e pili ana i: nā mea hoʻohui wai pauka, nā uhi pauka hoʻokaʻawale wela kiʻekiʻe, nā mea lawe adsorbent ʻala, nā mea anti-drip, nā mea friction pad brake, ka rubber silicone haʻahaʻa a me ka ʻaila silicone palaho ponoʻī, nā mea hoʻopihapiha pepa, a pēlā aku.
2. Magnesium Aluminum Silicate Porous Papa– Hoʻopaʻa wela a me ke kūpaʻa wela kiʻekiʻe
Pono kēia mineral silicate i ka calcination wela kiʻekiʻe me ka refractoriness a hiki i 1200°C. Hana nui ʻia me ka magnesium aluminum silicate, hōʻike ia i kahi ʻano porous momona e hāʻawi ana i ka ikaika hoʻopili kiʻekiʻe, ke kūpaʻa wai maikaʻi loa, ka lōʻihi o ka refractory, a me ke kumukūʻai kiʻekiʻe.
ʻO kāna mau hana nui e komo pū ana me ka pale wela kiʻekiʻe, ka hoʻemi ʻana i ka nui, ka hoʻonui ʻana i ka refractoriness, a me ka hoʻomaikaʻi ʻana i ke kūpaʻa ablation a me ka pale wela no nā papa kalapona a me nā pahu. Hoʻokomo pū ʻia nā noi me nā mea pale keramika, nā uhi pale ahi kiʻekiʻe, nā mea pale refractory, a me nā mea pale wela ablation-resistant.
3. Nā Microspheres Keramika - Ke kūpaʻa wela kiʻekiʻe, ka pale wela, ka ikaika hoʻopaʻa
ʻO nā microspheres aniani hakahaka he mea hoʻomehana wela maikaʻi loa ia, akā ʻaʻole lawa ko lākou kūpaʻa wela. ʻO ko lākou mau kiko palupalu maʻamau mai 650-800°C, me nā mahana heheʻe ma 1200-1300°C. Hoʻopaʻa kēia i kā lākou noi i nā hiʻohiʻona hoʻomehana wela haʻahaʻa. Ma lalo o nā kūlana wela kiʻekiʻe e like me ka ceramicization a me ke kūpaʻa ablation, lilo lākou i mea kūpono ʻole.
Hoʻoponopono kā mākou mau microspheres keramika hakahaka i kēia pilikia. Hana nui ʻia me ka aluminosilicate, hāʻawi lākou i ke kūpaʻa wela kiʻekiʻe, ka insulation wela maikaʻi loa, ka refractoriness kiʻekiʻe, a me ke kūpaʻa haki kiʻekiʻe. ʻO nā noi e pili ana i nā mea hoʻohui keramika silicone, nā mea insulation refractory, nā mea hoʻohui wela kiʻekiʻe no nā resins organik, a me nā mea hoʻohui rubber pale wela kiʻekiʻe. ʻO nā ʻāpana koʻikoʻi e pili ana i ka aerospace, ka ʻimi kai hohonu, nā mea composite, nā uhi, ka insulation refractory, ka ʻoihana petroleum, a me nā mea insulation.
He micropowder poepoe hakahaka kēia e kū pono ana i ka wela a maʻalahi loa ke hoʻohui (ʻaʻole e like me nā microspheres aniani hakahaka, e pono ai ka hoʻopuehu mua ʻana a i ʻole ka hoʻololi ʻana no ka hoʻohui kūpono) a hōʻike i ke kūpaʻa maikaʻi loa i ka māwae. ʻO kona hiʻohiʻona ʻokoʻa, he mea ia e wehe ʻia ana ma luna o ka ʻili, ʻaʻole ia e lana ma luna o ka wai, e maʻalahi ai ke hoʻomānoanoa a noho.
Eia kekahi, he ʻōlelo pōkole nopauka aerogel—he mea hoʻokaʻawale silica porous synthetic. Ua ʻike nui ʻia ʻo Aerogel he mea hoʻokaʻawale wela 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 aerogel o ka hoʻopuehu māmā loa a hoʻomaikaʻi i kona dispersibility. Loaʻa pū nā pastes aerogel wai no ka hoʻohui maʻalahi ʻana i loko o nā ʻōnaehana wai.
ʻO nā waiwai hoʻokaʻawale wela porous kū hoʻokahi o ka pauka aerogel e hiki ai i kāna hoʻohana ʻana i: – Nā mea lawe mea hoʻohui laholio a me ka plastik – Nā mea hoʻokaʻawale wela no nā pila ikehu hou – Nā uhi hoʻokaʻawale hale – Nā olonā lole hoʻokaʻawale wela – Nā panela hoʻokaʻawale hale – Nā uhi hoʻokaʻawale wela pale ahi – Nā mea hoʻopili hoʻokaʻawale wela.
