ʻO ka papa insulation XPS he papa i hoʻoheheʻe ʻia ʻo ia i hana ʻia me ka resin polystyrene ma ke ʻano he mea maka a me nā mea ʻē aʻe a me nā polymers, wela a hui pū ʻia a hoʻokomo ʻia me ka catalyst i ka manawa like, a laila extruded a hoʻoheheʻe ʻia.ʻO kona inoa ʻepekema ʻo ia ka extruded polystyrene foam (XPS) no ka pale ʻana i ka wela.Loaʻa i ka XPS kahi ʻano honeycomb paʻa paʻa paʻa, e hiki ai i ka papa XPS ke loaʻa ka haʻahaʻa haʻahaʻa o ka wai (aneane ʻaʻohe hoʻoheheʻe wai) a me ka haʻahaʻa haʻahaʻa haʻahaʻa., Ke kūpa'a ho'opi'i ki'eki'e, anti-aging (aneane 'a'ohe aging decomposition phenomenon i ka ho'ohana ma'amau).'O ka papa XPS he papa ili pa'a a me ka hale pa'a i loko.ʻOi aku ka haʻahaʻa o kāna conductivity thermal ma mua o ka EPS o ka mānoanoa like, no laila ʻoi aku ka maikaʻi o ka hana insulation thermal ma mua o EPS.

No ka pā hale like ʻole, hiki ke liʻiliʻi ka mānoanoa o ka papa xps ma mua o nā ʻano mea ʻokoʻa ʻē aʻe;ma muli o ka hale paʻa o ka papa o loko.No laila, loaʻa iā ia ke kūpaʻa maʻamau, a hiki ke mālama i ka hana insulation thermal maikaʻi i loko o kahi ʻāina humid;kūpono ia no nā hale me nā koi kūikawā no ka insulation thermal e like me ka mālama anuanu, a hiki ke hoʻohana ʻia no nā hale me ka pā pōhaku a i ʻole nā ​​​​pohaku e kū pono ana i nā mea.

ʻO ka papa polyurethane koʻikoʻi he haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana wela maikaʻi.Inā he 35～40kg/m3 ka mānoanoa nui o ka polyurethane pa'a, he 0.018g ~ 0.023w/(m·k) wale nō ka conductivity wela, ʻo ia ka hapalua o ka EPS, ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā mea insulation.ʻO ka papa polyurethane paʻa ka moisture-proof a me ka wai.ʻO ka helu kelepona paʻa o ka polyurethane paʻa ma luna o 90%, he mea hydrophobic, ʻaʻole ia e hoʻonui i ka conductivity thermal ma muli o ke komo ʻana o ka wai, a ʻaʻole e kahe ka pā i ka wai.

Ke hoʻohālikelike ʻia me nā mea insulating ʻē aʻe, ʻo ka polyurethane rigid foam ka mea ʻoi aku ka maikaʻi o ka hana insulation thermal.No laila, hiki i nā panela sandwich polyurethane lahilahi ke hoʻokō i nā hoʻoponopono kūpono e pili ana i ke kūkulu ʻana i nā palena hoʻohana ʻana i ka ikehu, e ʻae ai i ka hoʻohana ʻana i nā panela lahilahi i ka wā o ke kūkulu ʻana, e mālama ana i kahi hale;kūlana kūpaʻa a me ka hana kiʻekiʻe.I ka hihia o ka piʻi nui ʻana o ka noi, ʻo ka laina hana hana o nā panela sandwich polyurethane ʻaʻole wale e hoʻomaʻamaʻa i ka mana maikaʻi, akā lawe pū kekahi i ka hoʻokele waiwai a me ka hoʻokūkū.
