2. He kiʻekiʻe ka ʻoki ʻana, a ʻo ka hewa mānoanoa he ± 0.5mm, pēlā e hōʻoia ai i ka palahalaha o ka ʻili o ka huahana i hoʻopau ʻia.

3. Maikaʻi ka ʻōhū a ʻaʻahu like nā cell.

4. He māmā ka māmā nui, hiki ke hoʻemi i ke kaumaha pono'ī o ka huahana i hoʻopauʻia,ʻo ia ka 30-60% haʻahaʻa ma mua o ka huahana maʻamau.

5. ʻO ka ikaika compressive kiʻekiʻe, hiki ke kū i ke kaomi nui i ke kaʻina hana o nā huahana i hoʻopau ʻia.

6. He kūpono no ka nānā ʻana i ka maikaʻi.No ka mea, ua wehe ʻia ka ʻili a puni i ka wā o ka ʻoki ʻana, ua akaka ka maikaʻi o ka papa i ka nānā ʻana, kahi e hōʻoia ai i ka hopena insulation thermal o ka huahana i hoʻopau ʻia.​​

7. Hiki ke hanaʻia a hanaʻia ka mānoanoa e like me nā koi o ka mea hoʻohana.

Hoʻohālikelike o ka hana ʻana opapa hoʻokaʻawale polyurethaneme nā mea ʻokoʻa ʻē aʻe:

1. Nā hemahema o ka polystyrene: he maʻalahi ke puhi i ke ahi, e emi ma hope o ka lōʻihi o ka manawa, a he maikaʻi ʻole ka hana insulation thermal.

2. Nā hemahema o ka hulu hipa pōhaku a me ka hulu hipa aniani: hoʻopōʻino i ke kaiapuni, hoʻoulu ʻana i ka hua bacteria, hoʻoulu wai kiʻekiʻe, hopena insulation thermal maikaʻi ʻole, ikaika maikaʻi ʻole, a me ke ola lawelawe pōkole.

3. Nā hemahema o ka papa phenolic: maʻalahi i ka oxygen, deformation, kiʻekiʻe o ka wai absorption, kiʻekiʻe brittleness a maʻalahi e haki.

4. ʻO nā mea maikaʻi o ka polyurethane insulation board: flame retardant, haʻahaʻa haʻahaʻa thermal conductivity, maikaʻi thermal insulation hopena, kani kani, māmā a maʻalahi ke kūkulu.

Hana:

Nā kahua noi opapa hoʻokaʻawale polyurethane:

E like me ka mea nui o ka waihoʻoluʻu kila sandwich panels, ua hoʻohana nui ia i loko o ka hui hoʻomaʻemaʻe hale hana, nā papa hana, ke anu, a pela aku.
