I-PU ne-PIR polyurethaneindawo yokugcina ebandayoAmaphaneli aqashelwa kabanzi njengezinto zokuvikela ezisebenza kahle kakhulu ezitholakalayo zokwakha izindawo zokugcina izinto ezibandayo zanamuhla. Ukushisa kwawo okuphansi kakhulu kanye nokuqina kwesakhiwo okuhle kakhulu kuwenza abe yisisombululo esithandwayo sezindawo zokugcina izinto ezibandayo eziphakathi nendawo ezinkulu.
Ngokwamukelwa okukhulu kwamaphaneli e-polyurethane, izinhlelo zesimanje zokuhambisa izinto ezibandayo zithuthukise kakhulu ikhwalithi yokulondolozwa ngenkathi zinciphisa izindleko zokusebenza zizonke. Lawa maphaneli manje adlala indima ebalulekile engqalasizinda yezintambo ezibandayo ezonga amandla kuzo zonke izimboni zokudla, zemithi kanye nezezimboni.
Ukusebenza Okuvelele Kokuvimbela Amaphaneli Okugcina Izinto Ezibandayo zePolyurethane
Inzuzo eyinhloko yokuncintisana yamaphaneli okugcina abandayo e-polyurethane isesimeni sawo sangaphakathi samaseli avaliwe. Izindinganiso zemboni zidinga amaphaneli e-polyurethane asezingeni eliphezulu ukuze afinyelele izinga lamaseli avaliwe elingaphezu kwamaphesenti angama-95. I-ejenti ekhipha igwebu idala ama-micro-pores avaliwe ngaphakathi kwento eyinhloko, futhi la ma-pores avimba ngempumelelo izindlela zokudlulisa ukushisa. Ngenxa yalokho, ukushintshana kokushisa phakathi kwangaphakathi nangaphandle kwendawo yokugcina ebandayo kuhlala kuphansi kakhulu.
Ngenxa yalesi silinganiso esiphezulu samaseli avaliwe, amaphaneli e-polyurethane ngokuvamile afinyelela izinga lokuqhuba ukushisa eliphakathi kuka-0.018 no-0.024 W/m·K. Izinto zokuvimbela ukushisa zendabuko ezifana namabhodi oboya bedwala noma amaphaneli e-EPS polystyrene ngokuvamile zibonisa amanani okuqhuba ukushisa aphakathi kuka-0.035 no-0.045 W/m·K. Ngaphansi kwezidingo ezifanayo zokuvimbela ukushisa, amaphaneli e-polyurethane angafinyelela ukusebenza okuqondiwe cishe ngesigamu sobukhulu bezinto ezivamile. Le nzuzo inciphisa ngqo ukusetshenziswa kwesikhala sokwakha futhi ithuthukise ivolumu yokugcina esebenzisekayo.
Amaphaneli okugcina izinto ezibandayo e-polyurethane nawo alinganisela ukusebenza kokuvikela amandla omshini ngokusebenzisa ubuningi bezinto ezilawulwayo. Amaphaneli aphezulu avame ukugcina ubuningi be-foam obuphakathi kuka-38 no-40 kg/m³. Lolu hlu lubonisa iphuzu elihle kakhulu lokulinganisela phakathi kokuqina kwesakhiwo nokusebenza kahle kokushisa. Ubuningi obuphansi bunciphisa amandla okucindezela futhi bukhulisa ingozi yokuguquguquka. Ubuningi obukhulu buphakamisa ukuhanjiswa kokushisa kanye nezindleko zezinto ngaphandle kokunikeza izinzuzo ezilinganayo.
Imininingwane Yobuchwepheshe kanye Nezimo Zokusebenza
Abakhiqizi bavame ukukhiqiza amaphaneli okugcina izinto ezibandayo e-polyurethane ngokubopha i-polyurethane foam eqinile phakathi kwezingqimba ezimbili zamashidi ensimbi apendwe ngaphambilini. Lesi sakhiwo esihlanganisiwe sinikeza kokubili ukufudumala nokuqina kwendawo. Ukukhetha ubukhulu bephaneli kulandela iziqondiso eziqinile ezisekelwe ekushiseni.
Amaphaneli anobukhulu obungu-50 kuya ku-100 mm afanelana nezindawo zokugcina ezintsha ezingaphezu kuka-0°C. Amakamelo okugcina abandayo asebenza cishe ngo-18°C ngokuvamile adinga amaphaneli aphakathi kuka-100 no-150 mm ubukhulu. Ezindaweni zokugcina izinto eziqandisa ngokushesha noma ezindaweni zokushisa eziphansi kakhulu ngaphansi kuka-25°C, onjiniyela bavame ukucacisa amaphaneli amakhulu asukela ku-150 kuya ku-200 mm. Lokhu kulungiswa kuqinisekisa amazinga okushisa angaphakathi azinzile futhi kuvimbela ukulahlekelwa kwamandla ngokweqile.
Amandla okucindezela ahlala enye ipharamitha ebalulekile ekwakhiweni kwesitoreji esibandayo. Amaphaneli kumele asekele imithwalo evela ezinhlelweni zokushelufa, ama-evaporator, kanye neminye imishini efakiwe. Amaphaneli okugcina abandayo e-polyurethane asezingeni eliphezulu ngokuvamile afinyelela amanani amandla okucindezela angaphezu kuka-150 kPa. Leli zinga liqinisekisa ukuthembeka kwesakhiwo isikhathi eside ngesikhathi sokusebenza okuqhubekayo.
Ukuphepha emlilweni nakho kuthinta ukukhethwa kwezinto. Amaphaneli amaningi okugcina izinto ezibandayo e-polyurethane ahlangabezana nezindinganiso zokumelana nomlilo ze-B1 noma ze-B2. Izinto zezinga le-B1 ziyazicima zingakapheli imizuzwana emithathu ngemva kokususwa komlilo. Izinto zezinga le-B2 ziyazicima zingakapheli imizuzwana emithathu kuya kweyisithupha. Lezi zakhiwo zinciphisa kakhulu izingozi zokusabalala komlilo futhi zithuthukisa ukuphepha kwesikhungo sonke.
Ukuqina kwezinto ezibonakalayo kugqamisa kakhulu amaphaneli ekhwalithi ephezulu. Amaphaneli okugcina amanzi abandayo e-polyurethane avame ukugcina amazinga okumunca amanzi angaphansi kwephesenti elilodwa. Asebenza ngokwethembeka futhi ebangeni lokushisa elibanzi kusukela ku--60°C kuya ku-+120°C. Lokhu kuqina kuqinisekisa ukusebenza kahle kokuvikela ngaphansi kwezimo zokusebenza ezinzima kanye nokujikeleza kwezinga lokushisa njalo.
Izinzuzo Zesakhiwo: Ubuchwepheshe Bokuxhumana Kolimi Nomsele Obufakazelwe
Amabhuloho abandayo amelela enye yezinsongo ezinkulu kakhulu ekusebenzeni kahle kokugcina indawo ebandayo. Amaphaneli okugcina indawo ebandayo e-polyurethane abhekana nale nkinga ngezinhlelo zokuxhuma ulimi oluvuthiwe kanye nomsele ezihlanganiswe nezindlela zokukhiya ezingavamile ezakhelwe ngaphakathi. Lezi zinhlelo zivumela amaphaneli ukuthi ahlangane kahle futhi akhe ungqimba lokuvikela oluqhubekayo.
Lo mklamo wesakhiwo uqinisekisa ukusebenza kahle kokuvala umthungo. Lapho abafaki befaka imichilo yokuvala yobungcweti kanye nama-foam fillers, ukuvuza komoya kanye nokulahlekelwa ukubanda emajoyintini kwehla kube amazinga amancane. Endaweni yokugcina izinto ezibandayo ehlanganisa cishe amamitha-skwele ayi-1,000, amaphaneli e-polyurethane asezingeni eliphezulu anganciphisa ukusetshenziswa kukagesi kwaminyaka yonke ngamaphesenti angaba ngu-20 kuya kwangu-30 uma kuqhathaniswa nezinto zokuvikela ezivamile. Lokhu kunciphisa kuholela ezinzuzweni ezinkulu zezomnotho zesikhathi eside kanye nembuyiselo esheshayo ekutshalweni kwezimali.
