Isingeniso
Eminyakeni yakamuva,ama-catalyst e-polyurethane anephunga eliphansi sekuyinkambiso yentuthuko embonini ye-polyurethane. Njengoba kunezindinganiso zemvelo zomhlaba eziqinile kanye nesidingo samakhasimende esikhulayo sezindawo ezihlanzekile zangaphakathi, inkambiso yentuthuko yeama-catalyst e-polyurethane akhipha ukungcola okuncane, anephunga eliphansi kuyashesha. Abakhiqizi bama-foam aguquguqukayo naqinile, okokumboza, okunamathelayo, kanye nezinto zokuvala okwamanje babeka phambili ama-catalyst ahlanganisa ukusebenza okuphezulu, i-VOC ephansis, futhiubungane nemvelo ngaphandle kokubeka engcupheni ukusabela ngendlela engalungile.
Kungani Iphunga Libalulekile Ekukhiqizweni Kwe-Polyurethane
Ama-catalyst e-amine endabuko, yize esebenza kahle kakhulu ekukhuthazeni ukusabela kwe-polyurethane phakathi kwama-isocyanates nama-polyol, avame ukukhulula ama-amine aguquguqukayo ngesikhathi sokukhiqizwa noma ngemuva kokwelashwa. Lokhu kukhishwa kungaholela ku:
Siphunga elinamandla le-amines emikhiqizweni eqediwe (njengezimbozo nama-coating)
Ngaphakathiizinkinga zekhwalithi yomoya
Umsebenziizinkinga zokudalulwa kanye nokuhambisana nomthetho
Ukuze kuhlangatshezwane nezidingo zamanje zezempilo nezemvelo, izimboni ziyashintsha ngokushesha ziyeizinhlelo ze-catalyst ezinephunga eliphansi, eziguquguqukayo kancaneLezi zikhuthazi zinciphisa ukukhishwa kwegesi ngenkathi zigcina ukusebenza kahle kokukhipha igwebu kanye nokupholisa.
Ukwanda Kwezikhangisi Ze-Amine Ezingenaphunga Eliphansi
Ama-catalyst e-polyurethane anephunga eliphansi aklanyelweukunciphisa ukuguquguquka nokuthuthukisa ukukhethaNgokushintsha isakhiwo sawo sama-molecule noma ukwethula amaqembu asebenzayo asabelayo, lawa ma-catalyst angahlangana ngamakhemikhali ne-polyurethane matrix, ngaleyo ndlela avimbele ukuguquguquka kwamakhemikhali akhiqiza iphunga.
Ubuchwepheshe obuhamba phambili kulo mkhakha buhlanganisa:
Ama-catalyst e-amine asebenzayolokho kuhlangana ndawonye ku-polymer
Ama-catalyst e-amine avinjiwengokukhululwa okulawulwayo ngesikhathi sokusabela
Izinhlelo ze-amine ezikhipha ukungcola okuphansingokuqina kwe-hydrolytic okuthuthukisiwe
Isibonelo, izinto ezibangela ukucindezeleka ezifana neMingxu New MaterialsI-MXC-R40 futhiI-MXC-37 zenzelwe ngqo ukukhombisaiphunga eliphansi, ukusabela okuphezulu, kanye nezakhiwo ezilinganiselayo zejeli le-foamingZisetshenziswa kabanzi ku-amagwebu aqinile okufutha, izinto zokuvimbela uthuli, amagwebu angaphakathi kwezimoto, futhi Izinhlelo ze-HFO.
Abashayeli Bezemvelo Nemithetho
Izici eziningana zomhlaba wonke ziyasheshisa ukwamukelwa kweama-catalyst e-polyurethane anephunga eliphansi:
Ngokwandayoimithetho eqinile ye-VOC (i-volatile organic compound) kanye nokukhishwa komoya eYurophu, eNyakatho Melika, nase-Asia.
Izitifiketi zokusimama (LEED, BREEAM, GREEGUARD) bakhuthaza ukusetshenziswa kwezinto ezihlanzekile.
Isidingo sabathengi ifenisha ekhipha ukungcola okuncane, omatilasi, kanye nezindawo zangaphakathi zezimoto ziyakhula.
Ukushintshela embonini kuya ku-HFO kanye nezinhlelo zokukhipha amagwebu ezishaywa ngamanzi, ezidinga ama-catalyst akhethekile kakhulu.
Abakhiqizi abasebenzisaubuchwepheshe be-catalyst obukhipha ukungcola okuphansi akugcini nje ngokuhlangabezana nezidingo zomthetho kodwa futhi kuthuthukisa inani lomkhiqizo futhi kuzuze inzuzo yokuncintisana ezimakethe zokuthumela kwamanye amazwe.
Izinzuzo Zokusebenzisa Ama-Catalyst E-Polyurethane Angenaphunga Eliphansi
Ukuqalisaama-catalyst anephunga eliphansiEkukhiqizweni kwe-polyurethane kunikeza izinzuzo eziningi:
Iphunga elinciphile emikhiqizweni ye-foam eqediwe
Ukuphepha kwabasebenzi okuthuthukisiwe kanye nendawo yezitshalo
Ikhwalithi yomoya yangaphakathi engcono kubasebenzisi bokugcina
Ukuhambisana nezindinganiso zokukhishwa kwe-VOC
Ukusebenza okuzinzile kanye namaphrofayili okuphakama kwe-foam aqhubekayo
Lezi zinzuzo zenzaama-catalyst e-polyurethane anephunga eliphansi ukukhetha okukhethwe kabanzi kwabakhiqizi be-foam emhlabeni jikelele.
Izicelo Kuzo Zonke Izinhlelo Ze-Polyurethane
Ama-catalyst angenaphunga eliningi manje asetshenziswa cishe kuzo zonke izinhlelo ze-polyurethane:
Amagwebu aguquguqukayo: izihlalo zezimoto, imicamelo yefenisha, omatilasi
Amagwebu aqinile: amaphaneli okushisa, ama-spray foam, ama-freezer foam
Izimbozo, izinamathiseli, izivalo, kanye nama-elastomer (CASE): edinga ukusebenza okungephuzi, okunokukhishwa okuncane komoya
Ngokuqondene,Ukufakwa kwe-foam yesifutho esifuthwayo nge-HFOizinhlelo zizuza kuma-catalyst anephunga eliphansi agcina umsebenzi ophezulu ngenkathi evimbela iphunga lama-amine elingafuneki ezindaweni zokwakha ezivalekile.
Isiphetho
Umkhuba oya ku-ama-catalyst e-polyurethane anephunga eliphansi akubonisi nje kuphela impendulo emithethweni kodwa futhi nokuthuthuka kwemboni ekuqhubekeni kokusimama, ukuphepha, kanye nokuthuthukiswa kwekhwalithi. Ngokusebenzisa ubuchwepheshe obuthuthukisiwe ubuchwepheshe be-catalyst obukhipha ukungcola okuphansi, abakhiqizi be-polyurethane bangafeza ukukhiqizwa okuhlanzekile, izinto ze-foam ezisebenza kahle kakhulu, kanye nokwaneliseka kwabasebenzisi bokugcina okwandisiwe.
Njengomunye wabahlinzeki abahamba phambili baseShayina be-polyurethane catalysts,Izinto Ezintsha ze-Mingxu ithuthukisa njalo izinto ezintshaama-catalyst angenaphunga eliningi, asebenza kahle kakhulu ukuhlangabezana nezidingo zezinhlelo ze-foam zesimanje. Iphothifoliyo yethu yomkhiqizo ifaka phakathiI-MXC-R40, MXC-37, kanye ne-MXC-DPA, enikeza izixazululo ezifanele kakhulu kumakhasimende afuna ibhalansi phakathi kokusabela, ukuzinza, kanye nomthwalo wemfanelo wezemvelo.
