ʻO nā mea ʻeluaNā panela PIRa menā panela mālama anue pili ana i nā mea hoʻomehana hana kiʻekiʻe. ʻO ka ʻokoʻa nui ma ka mea a me ka hoʻokūpaʻa ʻana i ka hana: ʻO nā panela PIR (nā panela polyisocyanurate) he hoʻonui holomua o ka polyurethane (PUR), nona ka pale ahi maikaʻi loa, ke kūpaʻa wela kiʻekiʻe (a hiki i ka 200 ℃ a ma luna), a me ka haʻahaʻa o ka omo wai (haʻahaʻa loa ma mua o PUR). ʻO lākou ke koho mua no ke kūkulu ʻana i nā hale mālama anu kiʻekiʻe, nā hale hana meaʻai, a me nā hale ʻē aʻe. ʻO nā "panela mālama anu" e pili ana i nā mea hoʻomehana i hoʻohana ʻia i ka mālama anu, hiki ke PIR, PUR, XPS, etc. Ma muli o kāna hana piha, ua lilo ʻo PIR i mea nui o nā mea kiʻekiʻe o kēia wā.nā panela mālama anu.
Nā ʻano kumu o ka papa PIR (Polyisocyanurate):
Ke Kū'ē Ahi Kiʻekiʻe: Ma ka hoʻonui ʻana i ka nui o ke apo isocyanate, ʻoi aku ka nui o kona kū'ē ahi ma mua o ka panela PUR maʻamau, e hoʻokō ana i kahi helu ahi B1.
Palena Wela Kiʻekiʻe: Haʻahaʻa loa ka hoʻoili wela (≤0.023 W/mK), e hopena ana i ka pono pale kiʻekiʻe.
Ke Kū'ē Mahana Kiʻekiʻe: Hiki i ka hoʻohana lōʻihi ke kū i nā mahana ma luna o 150 ℃, a hiki i 205 ℃, kūpono no nā wahi wela kiʻekiʻe.
ʻO ka omo wai haʻahaʻa: ʻO ka nui o ka omo wai haʻahaʻa loa, e pale pono ana i ka komo ʻana o ka makū a mālama i ka hana insulation.
Ikaika Kiʻekiʻe: Kiʻekiʻe ka nui, kūkulu paʻa, hoʻoikaika i ka ikaika o ka hale.
Pilikino i ke kaiapuni: ʻAʻohe CFC.
Nā Panel Mālama Anu:
Manaʻo Laulā: Pili i nā panela sandwich āpau i hoʻohana ʻia i ke kūkulu ʻana i nā hale mālama anu; ʻo ka hana nui ka insulation a me ka sila ʻana.
Nā Mea Hana like ʻole: Ma waho aʻe o ka papa PIR maʻamau, loaʻa pū kekahi iā PUR (polyurethane), XPS (extruded polystyrene), a pēlā aku.
Kālele Hana: Koho ʻia nā mea koʻikoʻi like ʻole e like me nā koi mahana o ka mālama anu.
Nā Panel PIR vs. Nā Panel Mālama Anu PUR Maʻamau
Ke kū'ē ʻana i ke ahi: PIR > PUR
Ke kū'ē ʻana i ka mahana: PIR (-196℃ + 205℃) > PUR (-185℃ + 110℃)
Ka omo ʻana o ka wai: PIR (<1%)< PUR (2.5%~3%)
Ka nui o ka paʻa: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Kumukūʻai: ʻOi aku ke kiʻekiʻe o ka PIR ma mua o ka PUR.
Hōʻuluʻulu manaʻo
He mau panela PIR nā panela mālama anu hana kiʻekiʻe, kūpono loa no nā ʻoihana logistics kaulahao anu hou a me nā ʻoihana hana meaʻai me nā koi koʻikoʻi no ke kū'ē ʻana i ke ahi, ke kū'ē ʻana i ka mahana kiʻekiʻe, a me ka omo haʻahaʻa o ka makū. Hāʻawi lākou i kahi hopena insulation palekana a hilinaʻi hoʻi ma mua o nā panela lumi anu PU kuʻuna.
