KokubiliAmaphaneli e-PIRfuthiamaphaneli okugcina izinto ezibandayobheka izinto zokuvikela ezisebenza kahle kakhulu. Umehluko omkhulu usekugcizelelweni kwezinto zokwakha kanye nokusebenza kwazo: Amaphaneli e-PIR (amaphaneli e-polyisocyanurate) ayithuthukisi elithuthukisiwe kakhulu le-polyurethane (PUR), anokumelana okuhle kakhulu nomlilo, ukumelana nokushisa okuphezulu (kufika ku-200℃ nangaphezulu), kanye nokumuncwa komswakama okuphansi (okuphansi kakhulu kune-PUR). Ayindlela yokuqala yokwakha izindawo zokugcina ezibandayo ezidingekayo kakhulu, izitshalo zokucubungula ukudla, kanye nezinye izakhiwo. “Amaphaneli okugcina abandayo” ngokuvamile abhekisela ezintweni zokuvikela ezisetshenziswa endaweni yokugcina ebandayo, okungaba yi-PIR, PUR, XPS, njll. Ngenxa yokusebenza kwayo okuphelele, i-PIR isibe yindawo eyinhloko yesimanje ephezulu.amaphaneli okugcina izinto ezibandayo.
Izici Eziyinhloko Zebhodi le-PIR (Polyisocyanurate):
Ukumelana Nomlilo Okuphakeme: Ngokwandisa ukugcwala kwendandatho ye-isocyanate, ukumelana kwayo nomlilo kudlula kakhulu okwephaneli evamile ye-PUR, kufinyelela isilinganiso somlilo se-B1.
Ukushisa Okuphezulu: Ukushisa okuphansi kakhulu (≤0.023 W/mK), okuholela ekusebenzeni kahle kokushisa okuphezulu.
Ukumelana Nokushisa Okuphezulu: Ukusetshenziswa kwesikhathi eside kungamelana namazinga okushisa angaphezu kuka-150℃, ngisho nakufika ku-205℃, okulungele izindawo ezishisa kakhulu.
Ukumuncwa Kwamanzi Okuphansi: Izinga lokumuncwa kwamanzi eliphansi kakhulu, okuvimbela ngempumelelo ukungena komswakama nokugcina ukusebenza kokuvikela.
Amandla Aphezulu: Ubuningi obuphezulu, isakhiwo esizinzile, okwandisa amandla esakhiwo.
Kunobungani Nemvelo: Akukho CFC.
Amaphaneli Okugcina Izinto Ezibandayo:
Umqondo Obanzi: Kubhekiselwa kuwo wonke amaphaneli esandwich asetshenziswa ekwakheni izindawo zokugcina izinto ezibandayo; umsebenzi oyinhloko ukuvikela nokuvala.
Izinto Ezihlukahlukene: Ngaphezu kwebhodi le-PIR elijwayelekile, liphinde lifake i-PUR (polyurethane), i-XPS (i-polystyrene ekhishwe), njll.
Ukugxila Kokusebenza: Izinto eziyinhloko ezahlukene zikhethwa ngokuya ngezidingo zokushisa zesitoreji esibandayo.
Amaphaneli e-PIR vs. Amaphaneli Okugcina Abandayo e-PUR Ajwayelekile
Ukumelana Nomlilo: PIR > PUR
Ukumelana Nokushisa: I-PIR (-196℃ + 205℃) > I-PUR (-185℃ + 110℃)
Ukumuncwa Kwamanzi: PIR (<1%)< I-PUR (2.5%~3%)
Ubuningi: I-PIR (40-45 kg/m³) > I-PUR (38-40 kg/m³)
Izindleko: I-PIR ngokuvamile iphakeme kune-PUR.
Isifinyezo
Amaphaneli e-PIR amelela amaphaneli okugcina izinto ezibandayo asebenza kahle kakhulu, afaneleka kakhulu embonini yesimanje yezokuthutha kanye neyokucubungula ukudla enezidingo eziqinile zokumelana nomlilo, ukumelana nokushisa okuphezulu, kanye nokumuncwa komswakama ophansi. Anikeza isisombululo sokuvikela esiphephile nesithembekile kakhulu kunemaphaneli endabuko egumbi lokubanda le-PU.
