Ama-polyurethane foam aqinile asetshenziswa kabanzi ezimbonini ezifana nokwakha, ukuvikela ukushisa, izimoto, kanye nokuqandisa. Ama-polyurethane foam aqinile anamandla aphezulu okusebenza, izakhiwo ezinhle kakhulu zokuvikela ukushisa, kanye nokumelana nezici zemvelo, futhi asebenza kahle ezinhlotsheni eziningi zezicelo ezidinga amandla. Esinye sezici ezibalulekile ekuthuthukiseni ukusebenza kwama-polyurethane foam aqinile ukusetshenziswa kwama-polyurethane catalysts.
Ama-catalyst e-polyurethane, njenge-MXC-C15, idlala indima ebalulekile ekulawuleni ukusabela kwamakhemikhali ngesikhathi senqubo yokukhiqiza igwebu, ngaleyo ndlela ithinta izakhiwo zomzimba nezamakhemikhali zomkhiqizo wokugcina wegwebu. I-MXC-C15 (Inombolo ye-CAS 6711-48-4) iyi-catalyst ye-amine engakhiphi, enephunga eliphansi, esabelayo ethuthukisa ukwakheka nesakhiwo samagwebu e-polyurethane aqinile ngokuthuthukisa ukusabela okufiselekayo phakathi kwezingxenye ze-isocyanate ne-polyol. Ake sibheke kabanzi ukuthi ama-catalyst e-polyurethane afana ne-MXC-C15 athinta kanjani izakhiwo zamagwebu e-polyurethane aqinile.
Izakhiwo Ezithuthukisiwe Zomzimba
I-polyurethane foam eqinile inezakhiwo ezinhle zomzimba, futhi ama-catalyst e-polyurethane adlala indima ebalulekile ekwenzeni lezi zimfanelo zibe ngcono. Ezinye zezakhiwo ezibalulekile zomzimba ze-polyurethane foam eqinile zifaka:
Ubuningi kanye nobuqotho besakhiwo
Ubuningi be-foam eqinile ye-polyurethane buvame ukuba phakathi kuka-30-40 kg/m2³, okunikeza ibhalansi engcono kakhulu yamandla nesisindo. Ama-catalyst e-polyurethane afana ne-MXC-C15 asiza ukulawula inqubo yokugqwala, okuholela esakhiweni seseli esihle nesilinganayo. Lesi sakhiwo sibalulekile ekuqinisekiseni amandla okucindezela, ukuqina kanye nobuqotho besakhiwo se-foam. Ngenxa yalokho, i-polyurethane foam eqinile ingasetshenziswa ezinhlotsheni ezifana nokufakwa kwesakhiwo kanye namaphaneli athwala umthwalo ngaphandle kokuphazamisa ukusebenza.
Ukufakwa Kwe-Thermal kanye Nokusebenza Okuphansi Kokushisa
Esinye sezimpawu ezivelele ze-rogine polyurethane foam ukuguquguquka kwayo okuphansi kokushisa, okuvame ukuba phakathi kuka-0.018 no-0.024 W/mK. Lesi sici esihle kakhulu sokuvimbela ukushisa sisiza ukunciphisa ukusetshenziswa kwamandla futhi sithuthukise ukusebenza kahle kwamandla kwezakhiwo nezinhlelo. Indima yama-polyurethane catalysts ekulawuleni izinga lokusabela kanye nesakhiwo se-foam ibalulekile ekufezeni ukuguquguquka kokushisa okuphansi okufiselekayo. Ngokuthonya izigaba zokwanda nokwelapha, ama-catalysts afana ne-MXC-C15 avumela ijika lokusabela elibushelelezi, elifaka isandla esakhiweni samaseli esifana ne-foam, okuyisihluthulelo sokusebenza kwayo kokushisa.
Ukumelana Nomswakama Nokumelana Namanzi
Isakhiwo samaseli avaliwe se-polyurethane foam eqinile sithuthukisa ukumelana kwaso nomswakama kanye nokungena kwamanzi. Ama-catalyst e-polyurethane asiza ukuthuthukisa isakhiwo samaseli se-foam, aqinisekise ukuthi isilinganiso esiphezulu samaseli avaliwe siyafinyelelwa. Lokhu, nakho, kunikeza ukumelana kwamanzi okuphezulu, okwenza i-foam ifanele ukusetshenziswa ezindaweni zangaphandle lapho ukuchayeka kumswakama kuyinto ekhathazayo, njengasekufuleleni, ekushiseni udonga, kanye namaphaneli aqandisiwe.
Izakhiwo Zamakhemikhali Ezithuthukisiwe
Ama-catalyst e-polyurethane awathinti nje kuphela izakhiwo zomzimba ze-polyurethane foam eqinile kodwa futhi athinta izici zayo zamakhemikhali, okufaka isandla ekuqineni kwayo okuhlala isikhathi eside kanye nokumelana nezici ezahlukahlukene zemvelo.
Ukumelana namakhemikhali
Ama-foam e-polyurethane aqinile anokumelana okuhle kakhulu namakhemikhali ahlukahlukene, okuhlanganisa ama-acid, izisekelo, kanye nezinyibilikisi, okwenza kube ukukhetha okuthandwayo ezindaweni zezimboni ezinzima lapho i-foam ingase ihlangane nezinto ezibolayo. Ama-catalyst afana ne-MXC-C15 asebenza ngokusheshisa ukusabela kwe-urea (isocyanate-water) ngesikhathi senqubo yokukhiqizwa kwe-foam. Lokhu kusabela kusiza ukuthuthukisa ukuzinza nokuqina kwe-foam, ukuqinisekisa ukuthi igcina ukumelana namakhemikhali ngokuhamba kwesikhathi.
Ukuvimbela Umlilo
Ukumelana nomlilo kuyisici esibalulekile sezinto ezisetshenziswa ekwakheni, ekuthuthweni, nakwezinye izinhlelo zokusebenza ezibalulekile zokuphepha. Nakuba i-polyurethane foam eqinile ingasha ngokwemvelo, ingenziwa ingashi ngokufaka izithasiselo ezivimbela umlilo ekwakhiweni. Ama-catalyst e-polyurethane afana ne-MXC-C15 anegalelo ekukhuphukeni okubushelelezi nokulawulwayo kwe-foam ngesikhathi sokukhiqiza, okwenza i-foam ikwazi ukufaka lezi zithasiselo ngempumelelo. Lokhu kuphumela ku-foam eqinile kakhulu engahlangabezana nezindinganiso zokuphepha komlilo ngaphandle kokubeka engcupheni ezinye izakhiwo zayo.
Ukumelana Nemvelo Nokuguga
Ukuqina kwe-polyurethane foam eqinile kuthuthukiswa kakhulu yikhono layo lokubekezelela izici zemvelo ezifana nokushintshashintsha kwezinga lokushisa, umswakama kanye nokuchayeka ku-UV. Ama-catalyst e-polyurethane asiza ekwenzeni ngcono inqubo yokwelapha, aqinisekise ukuthi i-foam igcina amandla ayo nokuqina kwayo ngisho nasezimweni zemvelo ezinzima. Isakhiwo se-foam sihlala sinjalo futhi izakhiwo zayo zamakhemikhali zizinzile ngokuhamba kwesikhathi, okwenza kube ukukhetha okubanzi kokusetshenziswa kwesikhathi eside ezindaweni ezidinga kakhulu.
Indima Ka-I-MXC-C15Ezinhlelweni Ze-Foam Ze-Polyurethane Eziqinile
I-MXC-C15 iyisikhuthazi se-amine esisebenzayo esidlala indima ebalulekile ekwenzeni ngcono ukusabela kwamakhemikhali ngesikhathi sokukhiqizwa kwe-polyurethane foam eqinile. Iwusizo kakhulu ezinhlelweni ezidinga ijika lokusabela elibushelelezi nelilawulwayo. Ngokuthuthukisa ukwelashwa kwendawo kanye nokukhuthaza ukuqina okuphumelelayo ezinhlelweni zokubumba eziguquguqukayo, i-MXC-C15 iqinisekisa ukuthi i-foam igcina izakhiwo zayo zomzimba nezamakhemikhali kuyo yonke impilo yayo. Lesi sikhuthazi sinezinzuzo zokungabi bikho kokukhishwa kanye nephunga eliphansi, futhi sisetshenziswa kabanzi embonini yokuvikela imvelo.
Isiphetho
Ama-catalyst e-polyurethane abalulekile ekwakheni izakhiwo zomzimba nezamakhemikhali ze-foam eqinile ye-polyurethane. Ama-catalyst afana ne-MXC-C15 enza ngcono ukuqina kwe-foam, ukufudumala kokushisa, amandla esakhiwo, kanye nokumelana namakhemikhali. Umphumela uba yinto eguquguqukayo, eqinile esebenza kahle kakhulu ezinhlotsheni ezahlukahlukene zezimboni, zezentengiselwano, kanye nezindawo zokuhlala. Kungakhathaliseki ukuthi ukuthuthukisa ukusebenza kahle kwamandla, ukuthuthukisa ukubambezeleka komlilo, noma ukunikeza ukumelana nezingcindezi zemvelo, ukusetshenziswa kwama-catalyst e-polyurethane kuyisihluthulelo sokuvula amandla aphelele e-foam eqinile ye-polyurethane.
