Indima ye-Metal Catalyst MXC-B20 ekuphenduleni kwe-Polyurethane

I-MXC-B20, eyaziwa nangokuthi i-bismuth carboxylate catalyst MB20, iyisikhuthazi esinamandla se-polyurethane esisetshenziselwa ukuthuthukisa ukusabela kwe-polyurethane kanye nokwelapha. Njenge-carboxylate esekelwe ku-bismuth, i-MXC-B20 isebenza njenge-i-cocatalyst yensimbiokuvame ukuhlanganiswa nama-amine e-tertiary. Le nhlanganisela yenza kube lula ukupholisa ngokushesha, okwenza kube yindlela ephumelelayo yokusebenzisa ama-catalyst asekelwe ku-tin, avame ukusetshenziswa kumabhulokhi aguquguqukayo, ama-foam aguquguqukayo anamandla amakhulu, izembozo zokufutha, izinhlelo ze-microporous, kanye nezicelo ze-foam eqinile.

Izinzuzo zeI-MXC-B20

I-catalyst ye-MXC-B20 iletha izinzuzo eziningana embonini ye-polyurethane:

1. Ukusebenza Okuthuthukisiwe: I-MXC-B20 iyi-polyurethane eqinile noma i-gelled metal catalyst ebambezela ukwakheka kwe-viscosity yangaphambili ngemithamo ephansi, kodwa ikhuthaza ukuqina okuphezulu kwe-back-end. Lo mphumela obambezelekile uvumela ukulawula okungcono inqubo yokuqala yokusabela ngenkathi kuqinisekiswa izakhiwo zokugcina ezinhle kakhulu ze-foam.

2. Ukwakheka Okunobungani Nemvelo: Njengoba ingenazo izinsimbi eziyingozi njenge-mercury, i-lead, ne-dibutyltin, i-MXC-B20 inikeza enye indlela ephephile neyobungani nemvelo kunezinye izinto eziningi zendabuko zensimbi ezikhuthazayo. Futhi ayinazo izinguquko ezishintshashintshayo nephunga, okufaka isandla endaweni yokusebenza ephephile nejabulisayo.

3. Ukuhambisana: I-catalyst iyahambisana nama-polyol e-foam aqinile nathambile, okwenza ibe nokuguquguquka kwezindlela ezahlukene ze-foam, okuqinisekisa ukuhlanganiswa okubushelelezi ezinqubweni zokukhiqiza ezikhona.

Izicelo ze-MXC-B20

I-MXC-B20 idlala indima ebalulekile ekusheshiseni ukusabela lapho isikhathi sokupholisa singase singanele ngama-catalyst e-amine kuphela. Ukuhlanganiswa kwe-MXC-B20 ne-catalyst ye-amine kuvumela izikhathi zokusabela ezisheshayo kanye nezakhiwo ze-foam ezithuthukisiwe. Lokhu kwenze kwaba ukukhetha okuthandwayo kwezicelo ezahlukahlukene, njenge:

- Amagwebu Aqinile Esakhiwo Anobukhulu Obuningi: Ekukhiqizweni kwezingxenye zesakhiwo ezidinga ukuqina namandla, i-MXC-B20 iqinisekisa ukuqiniswa okusheshayo ngaphandle kokuphazamisa ubuqotho begwebu.

- Ukufakwa Kodonga Oluqinile Lokufutha: I-catalyst isheshisa ukuqiniswa kwe-foam yokufutha eqinile esetshenziswa ekufakweni kophahla, ihlinzeka ngokuqina kokushisa kanye namandla esakhiwo.

- I-Reactive Injection Molding (RIM): I-MXC-B20 ithuthukisa inqubo yokusabela kuzinhlelo zokusebenza ze-RIM, okuvumela izikhathi zomjikelezo ezisheshayo kanye nezingxenye ezibunjiwe eziqinile.

- Amagwebu Esikhumba E-Microlithic Anezimbobo Ezincane: Ezisetshenzisweni ezikhethekile lapho i-microporosity ibalulekile khona, i-MXC-B20 iqinisekisa ukwakheka kwegwebu okulinganayo kanye nekhwalithi.

Ikhono le-MXC-B20 lokukhuthaza izakhiwo ezinhle kakhulu ze-foam ngenkathi igwema ukusebenzisa izinsimbi eziyingozi lenza kube yisikhuthazo esibalulekile ekukhiqizweni kwe-polyurethane yesimanje.
