ʻO ka Polyurethane Foamed Composite Aerogel
Hoʻolauna
Hoʻokumu ʻia ka mea polyurethane aerogel compositefoamed ma ka hoʻohui ʻana i kahi mea insulating thermal silica aerogel pore filler a me kahi mea hoʻololi kū i ka wela phosphorus i kahi polyurethane paʻa maʻamau (RPUF). Ma o ka hoʻopiha ʻana i nā pore e hoʻonui i ke kaumaha.
a me ka hoʻololi ʻana o ka uhi ʻana o ka silica aerogel, ʻaʻole wale ka aerogeli i hoʻopuehu like ʻia i loko o ka nui o ka mea RPUF, akā aia mau ka hopena nanopore o ka aerogeli, a hoʻohana pono ʻia ka aerogeli. ʻO ka hopena ala lōʻihi palena ʻole, ka hopena baffle palena ʻole, a me ka hopena convection ʻole e hana i ka polyurethane i hoʻololi ʻia i loaʻa ka conductivity thermal maikaʻi loa me ka hoʻomaikaʻi ʻana i ka wela a me ka flameretardancy.
Palena：
| Nā kikoʻī ʻenehana | Papa Maʻamau |
| Mahana kūpaʻa wela | 150°C |
| ʻImi ʻOkikene | 29 |
| ʻIkepili hoʻokele wela | 0.027 |
| Hana hoʻopili (deformation10%) | 200kPa min |
| Pale ʻole i ka wai 0.2MPa, 30min | ʻaʻohe komo wai |
| Paʻa o ke ana (70°C, 48H) | 1.5% kiʻekiʻe loa |
| Laki o ke kelepona pani ʻia | 90% minuke |
| Ka helu omo wai | 3% max |
Pōmaikaʻi：
1. Hana maikaʻi o ka hoʻokaʻawale wela: ʻO ka conductivity wela ma kahi o 0.027, he mea maikaʻi ia no ka hoʻokaʻawale hale.
2. Hana maikaʻi ʻole i ka wai: Ua pani ʻia nā ʻāpana huʻa a ʻo ka helu sila he 95%. ʻAʻole hiki i ka wai ua ke komo ma o nā lua.
3. Hana hoʻopili maikaʻi: Hiki iā ia ke hoʻopili me ka lāʻau, ka metala, ka pōhaku, ke aniani a me nā mea ʻē aʻe me ka paʻa loa.
4. Maikaʻi Anti-kahiko: Wahi a nā haʻawina ʻenekinia haole a me ka noiʻi, hiki i ke kūpaʻa ʻana i ka ʻelemakule ke hiki i 30 mau makahiki.
5. Kū'ē i ka palaho: Paʻa loa nā waiwai kemika.
Noi：
Hiki ke hoʻopili ʻia ka polyurethane hoʻohuihui Aerogel i ka paipu insulation i kanu pololei ʻia. ʻO ka paipu insulation i kanu pololei ʻia, i ʻike ʻia hoʻi ʻo "pipe-in-tube", ua hana ʻia me ka papa pale waho polyethylene kiʻekiʻe-density, ka mea insulation plastic foam polyurethane paʻa a me ka paipu kila.
Loaʻa iā ia nā waiwai mechanical maikaʻi a me nā waiwai insulation thermal, a kū pinepine i nā mahana kiʻekiʻe 120 oC, Hiki i ka mea polyurethane foamed composite airgel ke hoʻonui i kona mahana kūpaʻa (a hiki i 150 oC), e hōʻemi i ka conductivity thermal o ka mea, a hoʻomaikaʻi maikaʻi i ke kūpaʻa wela, ka hopena insulation thermal a me nā waiwai mechanical o ka mea RPUF i hoʻololi ʻia.
