Zonse ziwiriMapanelo a PIRndimapanelo osungira oziziraTaganizirani za zipangizo zotetezera kutentha zomwe zimagwira ntchito bwino kwambiri. Kusiyana kwakukulu kuli mu zinthuzo ndi momwe zimagwirira ntchito: Mapanelo a PIR (mapanelo a polyisocyanurate) ndi apamwamba kwambiri a polyurethane (PUR), omwe ali ndi mphamvu yoletsa moto, amalimbana ndi kutentha kwambiri (mpaka 200℃ ndi kupitirira apo), komanso amayamwa chinyezi chochepa (chotsika kwambiri kuposa PUR). Ndiwo chisankho choyamba chomanga malo osungiramo zinthu zozizira, mafakitale opangira chakudya, ndi nyumba zina. "Mapanelo osungiramo zinthu zozizira" nthawi zambiri amatanthauza zipangizo zotetezera kutentha zomwe zimagwiritsidwa ntchito posungira zinthu zozizira, zomwe zingakhale PIR, PUR, XPS, ndi zina zotero. Chifukwa cha magwiridwe antchito ake onse, PIR yakhala njira yayikulu yogwiritsira ntchito zipangizo zamakono zamakono zamakono.mapanelo osungiramo zinthu zozizira.
Makhalidwe Aakulu a Bodi la PIR (Polyisocyanurate):
Kukana Moto Kwambiri: Mwa kuwonjezera kuchuluka kwa mphete ya isocyanate, kukana kwake moto kumaposa kwambiri kwa gulu la PUR wamba, zomwe zimapangitsa kuti ikhale ndi B1 fire rating.
Kuteteza Kutentha Kwambiri: Kutsika kwambiri kwa kutentha (≤0.023 W/mK), zomwe zimapangitsa kuti kutentha kukhale kogwira ntchito bwino.
Kukana Kutentha Kwambiri: Kugwiritsa ntchito kwa nthawi yayitali kumatha kupirira kutentha kopitilira 150℃, ngakhale mpaka 205℃, koyenera malo otentha kwambiri.
Kusayamwa Madzi Mokwanira: Kusayamwa madzi mochuluka kwambiri, kumateteza bwino kulowa kwa chinyezi komanso kumateteza kutentha kwa mpweya.
Mphamvu Yaikulu: Kuchulukana kwambiri, kapangidwe kokhazikika, kulimbitsa mphamvu ya nyumba.
Wochezeka ndi chilengedwe: Wopanda CFC.
Mapanelo Osungira Zinthu Zozizira:
Lingaliro Lalikulu: Limatanthauza mapanelo onse a masangweji omwe amagwiritsidwa ntchito popanga malo osungiramo zinthu zozizira; ntchito yaikulu ndi kutchinjiriza ndi kutseka.
Zipangizo Zosiyanasiyana: Kuwonjezera pa bolodi lalikulu la PIR, limaphatikizaponso PUR (polyurethane), XPS (polystyrene yotulutsidwa), ndi zina zotero.
Kuyang'ana pa Magwiridwe Antchito: Zipangizo zosiyanasiyana zapakati zimasankhidwa malinga ndi kutentha komwe kumafunika pa malo ozizira osungiramo zinthu.
Mapanelo a PIR vs. Mapanelo Osungira Zinthu Zozizira a PUR Okhazikika
Kukana Moto: PIR > PUR
Kukana Kutentha: PIR (-196℃ + 205℃) > PUR (-185℃ + 110℃)
Kumwa Madzi: PIR (<1%)< PUR (2.5%~3%)
Kuchuluka: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Mtengo: PIR nthawi zambiri imakhala yokwera kuposa PUR.
Chidule
Mapanelo a PIR ndi ofanana ndi mapanelo osungiramo zinthu zozizira omwe amagwira ntchito bwino kwambiri, makamaka oyenera makampani amakono okonza zinthu zozizira komanso mafakitale okonza chakudya omwe ali ndi zofunikira zolimba kuti asapse ndi moto, asapse ndi kutentha kwambiri, komanso asayamwe chinyezi chochuluka. Amapereka njira yotetezeka komanso yodalirika yotetezera kutentha kuposa mapanelo achikhalidwe a PU ozizira.
