Amaphaneli esandwich ayisici esibalulekile ezinhlelweni zokwakha nezokuvikela zanamuhla. Aqukethe izendlalelo ezintathu: into eyinhloko, evame ukwenziwa ngensimbi, i-fiberglass noma ezinye izinto ezihlanganisiwe, ezihlanganiswe phakathi kwezingqimba ezimbili zangaphandle. Lawa maphaneli anikeza ukuvikela okuhle kakhulu, isisindo esincane kanye namandla futhi asetshenziswa kabanzi ezinhlotsheni ezifana nezakhiwo zangaphambili, uphahla, amayunithi aqandisiwe kanye nezimoto zokuthutha.
Izinto Zokusetshenziswa Zamaphaneli Esandwich
Izendlalelo Zangaphandle (Amashidi Obuso)
Izendlalelo zangaphandle zivame ukwenziwa ngezinsimbi ezifana nensimbi, i-aluminium, noma i-fiberglass. Lezi zinto zinikeza ubuqotho besakhiwo, ukumelana nesimo sezulu, kanye nokuqina. Kwezinye izimo, izendlalelo zangaphandle zingenziwa ngama-polymer noma izinto ezihlanganisiwe, kuye ngezidingo zokusetshenziswa.
Izinto Eziyinhloko
Izinto eziyinhloko zibalulekile ekusebenzeni kokuvikela ukushisa kwephaneli yesandwich. Izinto ezivamile ezisetshenziselwa izinto eziyinhloko zifaka:
Igwebu le-polyurethane (PU): I-polyurethane foam inezakhiwo ezinhle kakhulu zokuvikela ukushisa futhi ivame ukusetshenziswa kumaphaneli e-sandwich. Njengoba inesilinganiso esiphakeme samandla kuya kwesisindo, i-polyurethane foam iyindlela ethandwayo kokubili yokuvikela ukushisa kanye nokusekelwa kwesakhiwo.
Igwebu le-Polyisocyanurate (PIR): I-PIR foam ingenye into eyinhloko esebenza kahle kakhulu enokumelana nokushisa okungcono kune-PU foam ejwayelekile. I-PIR ikhiqizwa ukusabela kwe-polyol kanye ne-isocyanate lapho kukhona i-catalyst.
Uboya bamaminerali kanye ne-polystyrene: Lezi zisetshenziswa nakwezinye izinhlelo zokusebenza, kodwa ngokuvamile azisebenzisi kahle ukushisa kunezimbobo ezisekelwe ku-polyurethane.
Inqubo Yokukhiqiza Amaphaneli Esandwich
Ukukhiqizwa kwamaphaneli esandwich ngokuvamile kuhilela izinyathelo ezilandelayo:
Ukulungiswa Kwezinto Eziyinhloko
Izinto eziyinhloko ngokuvamile ziyi-foam, eyenziwe ngengxube yama-polyol, ama-isocyanates, ama-catalysts kanye nezithasiselo. I-foam iyanwetshwa bese yenziwa amashidi. Kuma-foam e-polyisocyanurate (PIR), i-trimerization ibalulekile ukuze kufezwe izakhiwo zokuvikela ezifiselekayo. Yilapho ama-catalysts afana ne-MXC-TMA eqala khona ukusebenza.
Indima Yokusungula: Ukubaluleka Kwe-I-MXC-TMA
I-MXC-TMA iyi-catalyst ye-amine yesithathu eyisithako esibalulekile ekukhiqizweni kwama-foam e-polyisocyanurate. Ikhuthaza ukusabela kwe-trimerization (polymerization) yama-polyisocyanurates, okwakha ama-foam aqinile kuma-cores e-sandwich panel.
Ngokungafani nama-catalyst asekelwe ku-potassium,I-MXC-TMAIhlinzeka ngephrofayili yokuphakama efanayo nelawulwayo ngesikhathi sokwakheka kwefoam. Lokhu kuvumela ukugeleza okungcono kwefoam, okubalulekile ekusetshenzisweni okufana namaphaneli kanye nokufakwa kwesiqandisi okudinga isakhiwo sefoam esihambisanayo nesibushelelezi. Ukulawula ukusabela okufanayo kusiza ukugwema ukungahambisani njengokusatshalaliswa kwefoam okungalingani noma amaphutha kumkhiqizo wokugcina.
Ukusetshenziswa kwe-Core Phakathi Kwezendlalelo Zangaphandle
Uma i-foam core isidaliwe futhi izinzile, ibekwa phakathi kwezingqimba ezimbili zangaphandle zensimbi noma izinto ezihlanganisiwe. Izingqimba ziboshelwa ku-foam core, ngokuvamile zisebenzisa inhlanganisela yokushisa nokucindezela, okuqinisekisa isibopho esiqinile sokunamathela futhi kuvale i-core core endaweni yayo.
Ukwelapha kanye Nokulungiswa Kokugcina
Ngemva kokuba iphaneli yesangweji seyakhiwe, i-foam idlula enkambisweni yokwelapha lapho noma yikuphi ukusabela kwamakhemikhali okusele ku-foam kuqediwe. I-MXC-TMA idlala indima ekuthuthukiseni ukwelapha kwangemuva ekusetshenzisweni kwe-foam ebunjiwe okuguquguqukayo, ukuqinisekisa ukuthi i-foam ifinyelela ubulukhuni bayo obufanele kanye nokusebenza kahle kokuvikela.
Ukusika Nokubumba
Ekugcineni, amaphaneli esandwich asikwa ngokwezilinganiso ezifiselekayo zokusetshenziswa kwawo okukhethekile, kungaba ngezakhiwo zangaphambili, izindonga zokugcina izinto ezibandayo, noma ezinye izindlela zokusebenzisa. Amaphaneli abe eselungele ukufakwa ezindaweni ezahlukene zokwakha noma zezimboni.
Kungani i-MXC-TMA Ibalulekile Ekukhiqizweni Kwamaphaneli E-Sandwich
Ikhono le-MXC-TMA lokulawula ukusabela kwe-polyisocyanurate ngempumelelo lenza kube yinto ebalulekile ekukhiqizweni kwamaphaneli e-sandwich asezingeni eliphezulu. Ngokukhuthaza inqubo yokulungisa nokuthuthukisa ukugeleza kwamanzi, i-MXC-TMA iqinisekisa ukuthi umongo wokugcina we-foam unesakhiwo esivumelanayo, izakhiwo zokuvikela ukushisa eziphakeme, kanye namandla amahle kakhulu omshini. Lokhu kuphumela kumaphaneli e-sandwich aqinile futhi asebenzayo afanelekela izinhlelo zokusebenza eziningi ezahlukene.
Isiphetho
Ukukhiqizwa kwamaphaneli e-sandwich kuhilela inhlanganisela yezinto zokusetshenziswa kanye nobuchwepheshe bokukhiqiza ngokunemba. I-polyisocyanurate foam core eqhutshwa yimikhiqizo efana ne-MXC-TMA inikeza ukufudumala okudingekayo kanye namandla esakhiwo salezi zinto zokwakha eziguquguqukayo. Njengoba inekhono layo eliyingqayizivele lokulawula ukusabela kanye nokuthuthukisa ukugeleza, i-MXC-TMA iyisithako esibalulekile sokuqinisekisa ukusebenza kanye nekhwalithi yamaphaneli e-sandwich asetshenziswa ezimbonini ezahlukahlukene.
