Iipaneli zesandwich ziyinxalenye ebalulekileyo kwiinkqubo zokwakha zanamhlanje kunye nokufakelwa kwezinto zombane. Ziqulathe iileya ezintathu: izinto eziphambili, ezidla ngokwenziwa ngesinyithi, i-fiberglass okanye ezinye izinto ezidityanisiweyo, ezifakwe phakathi kweeleya ezimbini zangaphandle. Ezi paneli zibonelela ngokufakelwa kwezinto zombane okugqwesileyo, ubunzima obuphantsi kunye namandla kwaye zisetyenziswa kakhulu kwizicelo ezifana neefacade zokwakha, uphahla, iiyunithi ezifrijiweyo kunye nezithuthi zothutho.
Izinto eziluhlaza zeephaneli zesandwich
Iileya zangaphandle (Amaphepha obuso)
Iileya zangaphandle zihlala zenziwe ngeentsimbi ezifana nentsimbi, i-aluminium, okanye i-fiberglass. Ezi zinto zibonelela ngokuqina kwesakhiwo, ukumelana nemozulu, kunye nokuqina. Kwezinye iimeko, iileya zangaphandle zinokwenziwa ngee-polymers okanye izinto ezidityanisiweyo, kuxhomekeke kwiimfuno zokusetyenziswa.
Izinto ezingundoqo
Izinto eziphambili zibalulekile ekusebenzeni kwe-thermal insulation yephaneli yesandwich. Izinto eziqhelekileyo ezisetyenziselwa izinto eziphambili ziquka:
Ifoam yePolyurethane (PU): I-polyurethane foam ineempawu ezintle kakhulu zokuthintela ubushushu kwaye isetyenziswa kakhulu kwiipaneli zesandwich. Ngomlinganiselo ophezulu wamandla ukuya kobunzima, i-polyurethane foam lukhetho oludumileyo lokuthintela ubushushu kunye nenkxaso yesakhiwo.
Igwebu lePolyisocyanurate (PIR): Ifoam ye-PIR yenye into ephambili esebenza kakuhle enokumelana nobushushu okungcono kunefoam ye-PU eqhelekileyo. I-PIR iveliswa yimpendulo ye-polyol kunye ne-isocyanate xa kukho i-catalyst.
Uboya beminerali kunye nepolystyrene: Ezi zikwasetyenziswa nakwezinye iinkqubo, kodwa ngokubanzi azisebenzisi kakuhle ubushushu kuneefoam ezisekwe kwi-polyurethane.
Inkqubo yokuvelisa iiphaneli zesandwich
Ukuveliswa kweepaneli zesandwich kudla ngokubandakanya la manyathelo alandelayo:
Ukulungiswa kweZixhobo eziPhambili
Izinto eziphambili zihlala ziyi-foam, ezenziwe ngomxube wee-polyols, ii-isocyanates, ii-catalysts kunye nezinye izinto ezongezelelweyo. I-foam iyandiswa ize yenziwe ibe ngamaphepha. Kwi-polyisocyanurate (PIR) foams, i-trimerization ibalulekile ukuze kufezekiswe iipropati zokugquma ezifunekayo. Kulapho ke ii-catalysts ezifana ne-MXC-TMA zisebenza khona.
Indima yoKhathalelo: Ukubaluleka kweI-MXC-TMA
I-MXC-TMA sisithako esiphambili se-amine esiyinxalenye ebalulekileyo ekuvelisweni kweefoam ze-polyisocyanurate. Ikhuthaza ukusabela kwe-trimerization (polymerization) yee-polyisocyanurates, ezenza iifoam eziqinileyo zee-sandwich panel cores.
Ngokungafaniyo nee-catalysts ezisekelwe kwi-potassium,I-MXC-TMAInika iprofayili yokunyuka efanayo nelawulwayo ngexesha lokwenziwa kwefoam. Oku kuvumela ukuhamba kakuhle kwefoam, okubalulekileyo kwiindlela ezinje ngeepaneli kunye nokufakelwa kwefriji okufuna ulwakhiwo lwefoam oluhambelanayo nolugudileyo. Ulawulo lokuphendula olufanayo lunceda ekuphepheni ukungangqinelani okufana nokusasazwa kwefoam okungalinganiyo okanye iziphene kwimveliso yokugqibela.
Ukusetyenziswa kweCore phakathi kweeLayers zangaphandle
Nje ukuba isiseko sefoam senziwe saza sazinza, emva koko sidityaniswa phakathi kweengqimba ezimbini zangaphandle zesinyithi okanye izinto ezidityanisiweyo. Iingqimba zibotshelelwa kwisiseko sefoam, ngokuqhelekileyo kusetyenziswa indibaniselwano yobushushu kunye noxinzelelo, okuqinisekisa ukuba incamathisela ngokuqinileyo kwaye ivale isiseko sefoam endaweni yaso.
Ukulungisa kunye noLungiso lokugqibela
Emva kokuba iphaneli yesandwich yenziwe, ifoam idlula kwinkqubo yokunyanga apho naziphi na iimpembelelo zamakhemikhali eziseleyo kwifoam zigqityiwe. I-MXC-TMA idlala indima ekuphuculeni ukunyanga kwangasemva kwizicelo zefoam ezibunjiweyo eziguquguqukayo, ukuqinisekisa ukuba ifoam ifikelela kubunzima bayo obufanelekileyo kunye nokusebenza kakuhle kokugquma.
Ukusika nokubumba
Okokugqibela, iiphaneli zesandwich zisikwa ngokwemilinganiselo efunekayo ukuze zisetyenziswe ngokukodwa, nokuba zezokwakha iifacade, iindonga zokugcina izinto ezibandayo, okanye ezinye iindlela zokusetyenziswa. Emva koko iiphaneli zilungele ukufakwa kwiindawo ezahlukeneyo zokwakha okanye zoshishino.
Kutheni i-MXC-TMA ibalulekile kwiMveliso yeePaneli zeSandwich
Amandla e-MXC-TMA okulawula i-polyisocyanurate reaction ngokufanelekileyo enza ukuba ibe yimfuneko ekuvelisweni kweepaneli zesandwich ezikumgangatho ophezulu. Ngokukhuthaza inkqubo yokulungisa kunye nokuphucula ukugeleza kwamanzi, i-MXC-TMA iqinisekisa ukuba umongo wefoam wokugqibela unesakhiwo esihambelanayo, iipropati zokukhusela ubushushu eziphezulu, kunye namandla abalaseleyo oomatshini. Oku kuphumela kwiipaneli zesandwich ezihlala ixesha elide nezisebenzayo ezifanelekileyo kwiintlobo ngeentlobo zezicelo.
Isiphelo
Ukuveliswa kweepaneli zesandwich kubandakanya indibaniselwano yezinto eziluhlaza kunye nobuchwepheshe bokuvelisa ngokuchanekileyo. I-polyisocyanurate foam core ekhuthazwa ziimveliso ezifana ne-MXC-TMA inika ubushushu obufunekayo kunye namandla olwakhiwo lwezi zixhobo zokwakha ezinokusetyenziswa ngeendlela ezahlukeneyo. Ngenxa yamandla ayo ahlukileyo okulawula ukusebenza kwakhona kunye nokuphucula ukuhamba kwamanzi, i-MXC-TMA sisithako esiphambili sokuqinisekisa ukusebenza kunye nomgangatho weepaneli zesandwich ezisetyenziswa kumashishini ahlukeneyo.
