Indima Yama-Catalyst e-Polyurethane kuma-Sandwich Panels

Ibhodi lesangweji liyizinto zokwakha ezisebenziseka ngezindlela eziningi eziqukethe izendlalelo ezintathu: izendlalelo ezimbili zangaphandle (noma iziphetho) kanye nezinto zesendlalelo esiyinhloko phakathi. Enye yezinto ezivame kakhulu zesendlalelo esiyinhloko yi-polyurethane (PU) foam, enezakhiwo ezinhle kakhulu zokushisa kanye nokusekelwa kwesakhiwo. Isendlalelo esiyinhloko sivame ukufakwa phakathi kweziphetho eziqinile, ezivame ukwenziwa ngezinto zensimbi, ipulasitiki, noma eziqiniswe ngefayibha ezikhulisa amandla nokuqina kwephaneli. Izingxenye ezibalulekile ekukhiqizweni kwezingqimba zesisekelo se-polyurethane foam ezisebenza kahle kakhulu zamaphaneli esangweji yi-polyurethane catalysts, njenge-MXC-15 kanye ne-MXC-37.

Kungani i-Polyurethane Foam?

Ama-core e-polyurethane foam asetshenziswa kabanzi kuma-sandwich panels ngenxa yenani lawo elihle kakhulu lokuvikela (inani eliphezulu le-R), ubunjalo obulula, kanye nokusekelwa kwesakhiwo. La ma-panels avame ukusetshenziswa ezimbonini lapho ukuvikela ukushisa kanye nobuqotho besakhiwo kubalulekile khona, njenge:

1. Ukwakhiwa: Izinto eziyinhloko zinikeza ukuvikela okuhle kakhulu, okwenza izakhiwo zisebenzise kahle amandla. Isibonelo, lapho sisebenza endaweni yokugcina izinto ezibandayo, amaphaneli esandwich avikelayo anciphisa kakhulu izindleko zamandla ngokugcina izinga lokushisa elihambisanayo.
2. Isiqandisi kanye Nokugcina Izinto EzibandayoEzindaweni zokugcina izinto ezibandayo, amanani aphezulu okuvikela abalulekile ekugcineni amazinga okushisa aphansi.Ukumelana nokushisa kwe-polyurethane foam kwenza kube ukukhetha okubanzi kwamakamelo abandayo kanye namayunithi okuqandisa.
3. Izindiza kanye Nezasolwandle: Ezinhlelweni zezindiza kanye nezolwandle, ibhalansi phakathi kwesisindo namandla ibalulekile. Amaphaneli esandwich ane-PU foam cores ahlinzeka ngokusekelwa kwesakhiwo okudingekayo ngenkathi enciphisa isisindo.

Indima Ka-Ama-Catalyst e-Polyurethane

Ama-catalyst e-polyurethane, njenge-MXC-15 kanye ne-MXC-37, abalulekile ekusabeleni kwe-foam ngesikhathi sokukhiqizwa kwama-core e-foam e-polyurethane. Lawa ma-catalyst asheshisa ukusabela kwamakhemikhali phakathi kwe-polyol kanye ne-isocyanate, okwenza kube nokwakheka kwe-foam ezinzile enezakhiwo ezifiselekayo.

I-MXC-15: Kuyisikhuthazi se-isocyanurate esingabizi futhi esisebenzayo esinezinga eliphezulu lokuguqulwa. Kufanelekela ukwakheka kwe-polyol ene-viscosity ephezulu, kukhuthaza ukusabela kwe-isocyanate, umsebenzi ophezulu, osetshenziswa kakhulu kwi-PU hard foam, kufaka phakathi i-spray foam, i-PIR foam, kanye nohlelo lwe-PIR foam.

I-MXC-37: Eyaziwa nangokuthi i-DMAEE, ukwengeza i-DMAEE ku-polymer kunciphisa iphunga le-amine elivame ukutholakala kuma-foam. Ingasetshenziswa njenge-catalyst eyinhloko yodwa noma njenge-cocatalyst ukunciphisa ukusetshenziswa kwama-catalyst e-foam e-BDMAEE. Kwabaqinisi abasekelwe ku-ester, i-foam ethambile, i-foam encane, i-elastomer, i-RIM kanye ne-RRIM, kanye nezicelo zokupakisha i-foam eqinile.

Izinzuzo ze-Polyurethane Foam kuma-Sandwich Panels

1. Ukufakwa Okuphezulu Kokushisa (Inani Eliphezulu): I-polyurethane foam inenani eliphakeme kakhulu le-R nge-intshi uma kuqhathaniswa nezinye izinto zokuvikela. Lokhu kwenza amaphaneli esandwich ane-PU foam cores asebenzise kahle amandla kakhulu.
2. Ilula futhi Ihlala Isikhathi Eside: Ama-PU foam cores anciphisa isisindo sonke sephaneli yesangweji ngaphandle kokwehlisa amandla, okwenza abe afanele ukusetshenziswa lapho ukunciphisa isisindo kuyinto eza kuqala.
3. Ukumelana Nomswakama Nomlilo: I-polyurethane foam ingakhiwa ngezithasiselo zokuthuthukisa ukuvinjelwa komlilo kanye nokumelana nomswakama, kuthuthukiswe ukuphepha kanye nobude besikhathi samaphaneli esandwich ezindaweni ezahlukahlukene.
4. Ubuningi kanye namandla angenziwa ngezifiso: Ngokulungisa ukwakheka kanye nama-catalyst, abakhiqizi bangakhiqiza ama-foam anobukhulu obuhlukahlukene kanye nezakhiwo zemishini, okuvumela amaphaneli e-sandwich ukuthi ahlangabezane nezidingo ezithile zohlelo lokusebenza.

Isiphetho

Ama-catalyst e-polyurethane afana ne-MXC-15 kanye ne-MXC-37 abaluleke kakhulu ekukhiqizweni kwama-core e-polyurethane foam asebenza kahle kakhulu kuma-sandwich panels. Lawa ma-catalyst aqinisekisa ukuthi i-foam ihlangabezana nezimfuneko ezifunwayo, njengenani eliphezulu lokuvikela, amandla esakhiwo, kanye nokuqina. Ukuzivumelanisa nezimo kwe-polyurethane foam, kuhlanganiswe nokunemba kwama-catalyst esimanje, kuye kwaqinisa indawo yayo ezimbonini ezisukela ekwakheni kuya ekuqandisweni, ezimotweni, kanye nasezindiza. Ngokusungula izinto ezintsha kuma-catalyst formulations, abakhiqizi bangaqhubeka nokuthuthukisa ukusebenza kanye nokusimama kwama-sandwich panels.
