Ezinye izindlela zokusebenzisa ama-Tin Catalysts kuzinhlelo zokusebenza ze-Polyurethane: Ukugqanyiswa ku-MXC-MB20

Imboni ye-polyurethane ibilokhu ithembele kuma-catalyst asekelwe ku-tin ngenxa yendima yawo ephumelelayo ekusheshiseni ukusabela kanye nezinqubo zokupholisa. Kodwa-ke, ukukhathazeka ngezemvelo kanye nezempilo kuye kwabangela ukusesha ezinye izindlela ezisebenzayo. Esinye isici esithembisayo yilesi.I-MXC-B20, i-catalyst ye-bismuth carboxylate enikeza izinzuzo eziningi kune-catalysts yendabuko esekelwe ku-tin.

Kungani Kufanele Ucabangele Ezinye Izindlela Ezingasetshenziswa Esikhundleni Se-Tin Catalysts?

Ama-catalyst asekelwe ku-tin, njenge-dibutyltin dilaurate (DBTDL) kanye ne-stannous octoate, asetshenziswe kabanzi ekukhiqizweni kwe-polyurethane. Naphezu kokusebenza kwawo kahle, lawa ma-catalyst abeka izingozi ezinkulu zemvelo nezempilo. Angaba yingozi futhi avame ukuhlotshaniswa nemikhawulo yemithetho, okwenza kube kubalulekile kubakhiqizi ukuhlola izinketho eziphephile.

I-MXC-B20: I-Bismuth CarboxylateI-Catalyst

I-MXC-B20 iyi-catalyst entsha ye-bismuth carboxylate eyenzelwe ukubhekana nezinkinga zama-catalyst asekelwe ku-tin. Le catalyst isebenza njenge-cocatalyst enama-amine e-tertiary, ithuthukisa ukusabela kwe-polyurethane kanye nezinqubo zokupholisa. Lapha'ukubheka ngokucophelela ukuthi yini eyenza i-MXC-B20 ibe yindlela engcono kakhulu:

1. Ubungane Emvelweni:

I-MXC-B20 ayinazo izinto eziyingozi njenge-2-ethylhexanoic acid (2-EHA), i-dibutyltin (DBT), kanye ne-tributyltin (TBT). Lokhu kwenza kube inketho enobungani nemvelo uma kuqhathaniswa nama-catalyst asekelwe ku-tin avamile, okuhambisana nezidingo ezikhulayo zokulawula kanye nezemakethe zokwakheka kwamakhemikhali aphephile.

2. Ukusebenza Okuthuthukisiwe:

Ngezilinganiso eziphansi, i-MXC-B20 ikhulisa ukujiya kwangaphambi kwengxenye yengxube ye-polyurethane, ngaleyo ndlela yandisa ukubambezeleka. Lesi sici sizuzisa kakhulu njengoba sivumela ukulawula okungcono phakathi nezigaba zokuqala zokucubungula ngenkathi kuqinisekiswa ukuphiliswa okuhle kakhulu kwengxenye ye ...

3. Ukuguquguquka:

Le catalyst iyahambisana nama-polyol e-foam aqinile nathambile avamile, okwenza ifaneleke ezinhlelweni ezahlukene ze-polyurethane. Kungakhathaliseki ukuthi i-foam eguquguqukayo, i-foam eguquguqukayo enamandla kakhulu, i-spray foam, i-microcellular foam, noma izinhlelo ze-hard foam, i-MXC-B20 izibonakalisa iyi-catalyst eguquguqukayo nephumelelayo.

4. Okunye Okungafakwanga Ithini:

Ngokushintsha ama-catalyst asekelwe ku-tin nge-MXC-B20, abakhiqizi banganciphisa kakhulu ukuthinteka kwemvelo kwemikhiqizo yabo. Le ndlela engena-tin iphinde inciphise ingozi yobuthi, ikhuthaze indawo yokusebenza ephephile kanye nomkhiqizo wokugcina.

5. Imiphumela Eqhathaniswayo noma Ephakeme:

Naphezu kokungabikho kwe-tin, i-MXC-B20 ayikhiphi ukusebenza kwayo. Amandla ayo okusebenza njenge-cocatalyst enama-amine e-tertiary aqinisekisa ukuthi inqubo yokwelapha isebenza kahle futhi iyasebenza, ivame ukuveza imiphumela efana, noma engcono kakhulu kunaleyo etholakala ngama-catalyst asekelwe ku-tin.

Isiphetho

Ukushintshela kuma-catalyst aphephile futhi anobungani nemvelo kuyinto ebalulekile embonini ye-polyurethane. I-MXC-B20, enezakhiwo zayo ezihlukile nezinzuzo zayo, ivela njengendlela ehlukile ekhangayo kune-catalyst yendabuko esekelwe ku-tin. Ukuhambisana kwayo nezinhlobonhlobo zama-polyol, kuhlanganiswe nokusebenza kwayo okuthuthukisiwe kanye neziqinisekiso zemvelo, kwenza kube ukukhetha okuhle kakhulu kwabakhiqizi abafuna ukusungula nokuthuthukisa imikhiqizo yabo ye-polyurethane. Ukwamukela i-MXC-B20 akugcini nje ngokuhambisana nezidingo zomthetho kodwa futhi kukhuthaza ukusimama nokuphepha ekukhiqizweni kwe-polyurethane.
