ZombiniIiphaneli ze-PIRkwayeiiphaneli zokugcina izinto ezibandayobhekisa kwizinto zokukhusela ezisebenza kakuhle. Umahluko ophambili usekwe kwizinto kunye nogxininiso lokusebenza: Iiphaneli ze-PIR (iiphaneli ze-polyisocyanurate) ziphuculo oluphambili lwe-polyurethane (PUR), zinokuphelelwa lilangatye ngokugqwesileyo, ukumelana nobushushu obuphezulu (ukuya kuthi ga kwi-200℃ nangaphezulu), kunye nokufunxwa komswakama okuphantsi (okuphantsi kakhulu kune-PUR). Ziyindlela yokuqala yokwakha iindawo zokugcina izinto ezibandayo ezifunekayo kakhulu, izityalo zokulungisa ukutya, kunye nezinye izakhiwo. "Iiphaneli zokugcina izinto ezibandayo" ngokubanzi zibhekisa kwizinto zokukhusela ezisetyenziswa kwindawo yokugcina izinto ezibandayo, ezinokuba yi-PIR, PUR, XPS, njl. Ngenxa yokusebenza kwayo okubanzi, i-PIR ibe yeyona nto iphambili kwiindlela zanamhlanje eziphezulu.iiphaneli zokugcina izinto ezibandayo.
Iimpawu eziphambili zeBhodi yePIR (Polyisocyanurate):
Ukumelana Nomlilo Okugqwesileyo: Ngokwandisa uxinano lweringi ye-isocyanate, ukumelana kwayo nomlilo kudlula kakhulu oko kwephaneli eqhelekileyo ye-PUR, kufikelela kwinqanaba lomlilo le-B1.
Ubushushu obuphezulu: Ubushushu obuphantsi kakhulu (≤0.023 W/mK), nto leyo ebangela ukusebenza kakuhle kobushushu obuphezulu.
Ukumelana nobushushu obuphezulu: Ukusetyenziswa ixesha elide kunokumelana nobushushu obungaphezulu kwe-150℃, nokuba kufikelele kwi-205℃, kufanelekile kwiindawo ezinobushushu obuphezulu.
Ukufunxwa kwamanzi okuphantsi: Izinga lokufunxwa kwamanzi eliphantsi kakhulu, nto leyo ethintela ngempumelelo ukungena komswakama kunye nokugcina ukusebenza kobushushu.
Amandla Aphezulu: Uxinano oluphezulu, isakhiwo esizinzileyo, esomeleza amandla esakhiwo.
Ilungele okusingqongileyo: Ayinazo ii-CFC.
Iiphaneli zokugcina izinto ezibandayo:
Ingcamango eBanzi: Ibhekisa kuzo zonke iiphaneli zesandwich ezisetyenziswa ekwakheni iindawo zokugcina izinto ezibandayo; umsebenzi ophambili kukukhusela nokuvala.
Izinto ezahlukeneyo: Ukongeza kwibhodi ye-PIR eqhelekileyo, ikwaquka i-PUR (i-polyurethane), i-XPS (i-polystyrene ekhutshiweyo), njl.
Ukugxila kwiNtsebenzo: Izixhobo ezahlukeneyo eziphambili zikhethwa ngokweemfuno zobushushu kwindawo yokugcina ebandayo.
Iiphaneli zePIR vs. Iiphaneli zokugcina ezibandayo zePUR eziqhelekileyo
Ukumelana nomlilo: PIR > PUR
Ukumelana nobushushu: I-PIR (-196℃ + 205℃) > I-PUR (-185℃ + 110℃)
Ukufunxwa kwamanzi: PIR (<1%)< I-PUR (2.5%~3%)
Ubuninzi: I-PIR (40-45 kg/m³) > I-PUR (38-40 kg/m³)
Ixabiso: I-PIR ngokubanzi iphezulu kune-PUR.
Isishwankathelo
Iiphaneli ze-PIR zimele iiphaneli zokugcina izinto ezibandayo ezisebenza kakuhle, ngakumbi ezifanelekileyo kwimizi-mveliso yanamhlanje ye-cold chain kunye ne-processing food eneemfuno ezingqongqo zokumelana nomlilo, ukumelana nobushushu obuphezulu, kunye nokufunxwa komswakama okuncinci. Zibonelela ngesisombululo sokukhusela esikhuselekileyo nesithembekileyo kuneephaneli ze-PU zesiqhelo zegumbi elibandayo.
