I-polyurethane foam iyinto ebalulekile kumaphaneli e-sandwich, enikeza ukufudumala okuhle kakhulu, ukuzinza kwesakhiwo kanye nokusebenza kahle kokushisa. Amaphaneli e-sandwich avame ukusetshenziswa ekwakhiweni kwezakhiwo, izindawo zokugcina izinto ezibandayo kanye nezakhiwo zezimboni, futhi aqukethe izendlalelo ezimbili ezincane zezinto ezihlala isikhathi eside kanye ne-polyurethane foam foam elula. I-core yenziwe nge-polyurethane rigid foam futhi inegalelo elikhulu ekusebenzeni kwephaneli ngokuphathelene nokufudumala, ukuvikelwa komlilo kanye nokuqina kwesakhiwo. Ikhwalithi yale foam core incike kakhulu ku-polyurethane catalyst esetshenziswa ekukhiqizweni kwayo.
Ama-catalyst e-polyurethane adlala indima ebalulekile ekusabeleni kwamakhemikhali okuguqula ama-polyol nama-isocyanates abe yi-foam eqinile. Lawa ma-catalyst asheshisa inqubo yokuqhuma nokupholisa, eqinisekisa ukwakheka kweseli okufanayo, ukunamathela okufanele kanye nezakhiwo zomzimba ezifanele. Enye yalezi zi-catalyst yileI-MXC-15, isixazululo se-potassium octoate (CAS 3164-85-0), okuyi-catalyst ye-isocyanurate eguquguqukayo ephezulu, engabizi kakhulu. Ifaneleka kakhulu kuma-polyol formulations aphezulu futhi ingakhuthaza ngempumelelo ukusabela kwe-isocyanate.
Isicelo kuma-Sandwich Panels
Ingaphakathi le-polyurethane foam kumaphaneli e-sandwich kumele lihlangabezane nezindinganiso ezithile ukuqinisekisa ukuthi iphaneli isebenza kahle. Isibonelo, i-foam kumele ibe lula kodwa iqine ngokwanele ukumelana namandla okucindezela futhi inikeze ukuvikelwa kokushisa. Ngaphezu kwalokho, kwezinye izinhlelo zokusebenza, njengokugcina ebanda noma ukubanda kwezimboni, ukumelana nomlilo kubalulekile.I-MXC-15isabela kakhulu futhi isiza ekwakheni amagwebu e-polyisocyanurate (PIR), aziwa ngokumelana kwawo nomlilo okuthuthukisiwe, okwenza afaneleke kakhulu kulezo zinhlelo zokusebenza.
Ama-foam e-PIR anesilinganiso esiphezulu sama-isocyanurate bonds kune-polyurethane foam evamile, okuwanikeza ukumelana okuhle kakhulu nomlilo. I-MXC-15 ikhuthaza ukwakheka kwalezi zibopho, iqinisekisa ukuthi i-foam yokugcina inezakhiwo ezidingekayo kumaphaneli e-sandwich. Lokhu kwenza izinhlelo ze-PIR foam ezisekelwa yi-MXC-15 zibe ukukhetha okuthandwayo kwamaphaneli adinga ukuhambisana nezindinganiso zomlilo eziqinile.
Umthelela Ekhwalithini Yomkhiqizo
Ukukhetha i-catalyst kunomthelela omkhulu kwikhwalithi ye-foam core yephaneli yesandwich. Ama-catalyst afana ne-MXC-15 aqinisekisa ukusabela okubushelelezi nokulawulwayo kwe-foam, okuholela esakhiweni se-foam esivumelana kakhulu. Lokhu kubaluleke kakhulu ekukhiqizweni kwamaphaneli e-sandwich, njengoba ukufana kobuningi be-foam nosayizi weseli kuthinta izakhiwo zokushisa kanye namandla omshini wephaneli yesandwich. I-polyurethane foam eyenziwe kahle ehlanganiswe nama-catalyst afanele inganciphisa kakhulu ukudluliselwa kokushisa, ithuthukise ukusebenza kahle kokushisa kanye nokuqina kwesikhathi eside kwamaphaneli e-sandwich.
Ngaphezu kwalokho, ukusebenzisa ama-catalyst asebenza kakhulu njenge-MXC-15 kungakhiqiza ama-foam aqinile aneziphambeko ezincane. Ukuphakama okulawulwayo kanye nephrofayili ye-gelation kunciphisa amathuba okuba nezikhala noma amaphuzu abuthakathaka ku-foam, okuqinisekisa ubuqotho besakhiwo sephaneli yesangweji. Ngaphezu kwalokho, i-MXC-15 ifaneleka kuma-polyol formulations ane-viscosity ephezulu, okuqinisekisa ukuhambisana nezinhlobo ezahlukene zama-formulations, okwenza kube ukukhetha okuguquguqukayo kwabakhiqizi abafuna ukwenza ngcono izinqubo zabo zokukhiqiza amaphaneli.
Ngamafuphi, ama-catalyst e-polyurethane afana ne-MXC-15 adlala indima ebalulekile ekukhiqizweni kwamaphaneli e-sandwich, ikakhulukazi ekukhiqizweni kwama-core e-foam e-PIR. Umthelela wawo ekhwalithini ye-foam, izakhiwo zokushisa kanye nokumelana nomlilo akunakuthathwa kalula. Ngokukhetha i-catalyst efanele, abakhiqizi bangakhiqiza amaphaneli e-sandwich ahlangabezana nezindinganiso zokusebenza eziphezulu kanye nokuphepha, okwenza kube ukukhetha okubanzi kwezicelo ezahlukahlukene zokwakha nezezimboni.
