Iipaneli zesandwich zePolyurethane, ezaziwa ngokuba ziipaneli zePU, zizinto ezisetyenziswa kakhulu kulwakhiwo lwanamhlanje nakwimizi-mveliso ngenxa yamandla azo, ukuqina kwazo kunye neempawu zokugquma ubushushu. Iipaneli zenziwe ngamaleko amathathu aphambili: isiseko se-polyurethane foam esigquma kakhulu kwaye sihlanganiswe phakathi kwamaphepha amabini esinyithi aqinileyo. Esi sakhiwo sidibeneyo sinozinzo oluhle kakhulu lwesakhiwo, ukugquma kunye nokumelana nemozulu, okwenza ukuba sibe yindawo efanelekileyo kwiindawo ezahlukeneyo. Ii-catalysts zePolyurethane ekuvelisweni kwezi paneli ziqinisekisa ukwenziwa nokusebenza kakuhle kwee-foam cores.
Yintoni iSandwich Panel?
Iphaneli yesandwich luhlobo lwezixhobo zokwakha ezidibanisa isiseko se-polyurethane foam kunye neeleya zangaphandle, ngokuqhelekileyo isinyithi, ukwenza izinto ezidityanisiweyo ezisebenzayo kakhulu. Isiseko se-foam, esenziwe nge-chemical reaction ekhuthazwa yi-polyurethane catalysts, sibonelela ngobushushu obuhle kakhulu, sinceda ukugcina amaqondo obushushu angaphakathi azinzileyo kwizakhiwo nakwizixhobo. Iileya zangaphandle zesinyithi zongeza ukuqina kwesakhiwo, ukhuseleko, kunye nokuqina. Olu dibaniso lubonelela ngesisombululo esikhaphukhaphu kodwa esihlala ixesha elide kwiindonga, uphahla, indawo yokugcina ebandayo, kunye nezinye izinto apho ukusebenza kakuhle kwamandla, ubunzima, kunye namandla kubalulekile.
Indima yeeCatalysts zePolyurethane kwiiSandwich Panels
Ii-catalysts ze-polyurethane zibalulekile ekuveliseni i-foam core yeepaneli zesandwich. Ii-catalysts ezifana ne-MXC-T kunye ne-MXC-C15, nganye ineempawu ezahlukeneyo, zikhawulezisa ukusabela phakathi kwee-polyols kunye nee-isocyanates, nto leyo ekhokelela ekwakhekeni kwe-foam ngobuninzi kunye nesakhiwo esifunekayo.
1.I-MXC-TIsetyenziswa kakhulu ekuveliseni i-foam ethambileyo esekelwe kwi-polyether, i-foam ebunjiweyo, i-foam eqinisiweyo, kunye ne-rigid foam. Kwiiphaneli zesandwich, i-MXC-T inceda ekulawuleni ulwakhiwo lwe-foam, ibonelela ngesantya sokusabela esilinganayo kunye nolwakhiwo lweseli oluhambelanayo. Oku kuhambelana kuqinisekisa ukugquma kobushushu obufanayo kwaye kuphucula ukuthembeka kwesakhiwo sephaneli.
2.I-MXC-C15, i-amine catalyst, ifanelekile ngokukodwa ekubumbeni okuthambileyo nokuthambileyo kunye nokusetyenziswa kwe-foam eqinileyo. Kwiiphaneli zesandwich, inegalelo ekufezekiseni isakhiwo se-foam esizinzileyo esigcina iipropati zaso zokukhusela phantsi kwamaqondo obushushu ahlukeneyo. Ulawulo lwe-MXC-C15 malunga nempendulo lunceda ekufezekiseni uxinano olufanelekileyo lwe-foam kunye nozinzo olulinganayo, okwenza iiphaneli zikwazi ukumelana nokuguquguquka kunye noxinzelelo lokusingqongileyo.
Usetyenziso lweephaneli zesandwich zePU
Iipaneli zesandwich zePolyurethane zisetyenziswa kakhulu kwiindawo zokugcina izinto ezibandayo, kwizakhiwo zoshishino, kwizakhiwo zorhwebo, nakwiindawo zokuthutha ezifrijini, apho ukugcina ulawulo lobushushu kubalulekile. Iipaneli zesandwich zePolyurethane zilula, zikhawuleza ukufakwa, zinomthwalo omncinci kwisakhiwo, kwaye ziyamelana neemeko zemozulu ezimbi kakhulu ukuze zihlale ixesha elide. Ukusetyenziswa kwee-catalysts ze-polyurethane ezizinikeleyo kwinkqubo yemveliso kuphucula ezi mpawu, okwenza iipaneli zesandwich ze-polyurethane zibe lukhetho olubanzi lwezisombululo zokwakha ezisebenzisa amandla nezihlala ixesha elide.
Ngamafutshane, indibaniselwano ye-polyurethane foam kunye nee-catalysts ezisebenzayo eziphezulu ezifana ne-MXC-T kunye ne-MXC-C15 ivelisa iiphaneli zesandwich ezine-insulation egqwesileyo, amandla kunye nokumelana nemozulu, ezixhasa iindlela zokwakha ezizinzileyo nezisebenzayo.
