Ukukhiqizwa kwe-polyurethane foam kuncike kakhulu ekusetshenzisweni kwama-catalyst ukulawula isikhathi sokuphendula nokufeza izakhiwo ze-foam ezifiselekayo. I-MXC-B20 iyi-catalyst yejeli ye-polyurethane eguquguqukayo evelele ngenxa yekhono layo lokusebenza njengokufaka esikhundleni esiphumelelayo sama-catalyst asekelwe ensimbini yendabuko njenge-dibutyltin, i-lead, noma i-mercury. Njenge-catalyst, i-MXC-B20 ingahlanganiswa ngokubambisana nama-tertiary amines ukusheshisa ukusabela kwe-polyurethane, inikeze izikhathi zokuphulukisa okusheshayo kanye nezakhiwo ze-foam ezinhle kakhulu kuzo zonke izinhlelo zokusebenza. Ukuzivumelanisa nezimo kwalesi si-catalyst kubuye kufinyelele ekuvumelaneni kwayo nezinhlelo ze-Hydrofluoroolefin (HFO), ezithola ukubaluleka embonini ngenxa yomthelela wazo ophansi kwezemvelo.
Izindawo Eziyinhloko ZokusebenzisaI-MXC-B20
1. Amagwebu e-Polyurethane Aqinile I-MXC-B20Isebenza kahle kakhulu ekukhiqizeni amagwebu e-polyurethane aqinile, asetshenziswa kabanzi ekufakeni izinto zokuvikela kanye nezakhiwo. Lawa magwebu anikeza ukusebenza okuhle kakhulu kokushisa, ukuzinza kobukhulu, kanye namandla. Ezisetshenzisweni ezifana nokufakwa kodonga oluqinile kanye nesitokwe seshidi eliqinile, i-MXC-B20 iqinisekisa ukuphulukiswa okusheshayo ngenkathi igcina ikhwalithi yegwebu, ngisho nangesivinini esikhulu sokukhiqiza. Ngokugwema izinto zokuvuselela zensimbi zendabuko ezifana ne-dibutyltin, i-MXC-B20 inikeza inketho enobungani nemvelo ngenkathi igcina ukusebenza okuphezulu.
2. Amagwebu Aqinile Esakhiwo Esinobukhulu ObuningiAma-foam aqinile anesakhiwo esiqinile avame ukusetshenziswa ekwakheni nasezintweni ezisetshenziswayo zezimoto lapho kudingeka khona amandla nokuqina okuphezulu. I-MXC-B20 idlala indima ebalulekile ekufezeni izikhathi zokusabela okusheshayo ngaphandle kokubeka engcupheni izakhiwo ze-foam. I-catalyst ivumela ukukhiqizwa kwama-foam aqinile, ahlala isikhathi eside agcina ubuqotho besakhiwo sawo ezindaweni ezidinga amandla.
3. Amagwebu e-MicrocellularI-MXC-B20 ifaneleka kahle futhi ekukhiqizeni ama-foam amancane, alula futhi abonisa izakhiwo zamaseli ezinhle nezilinganayo. Lawa ma-foam avame ukusetshenziswa ezingxenyeni zezimoto, ezithendeni zezicathulo, nakwezinye izinhlelo zokusebenza lapho ukumelana nokushayisana, induduzo, kanye nobuningi obuphansi kuyizidingo ezibalulekile. I-MXC-B20 ikhuthaza ukuphiliswa okusheshayo ngenkathi igcina isakhiwo sama-microcellular, inikeza izinga eliphezulu lokuvumelana kanye nekhwalithi kumkhiqizo wokugcina.
4. Amagwebu Aguquguqukayo Kancane AqinileEzinhlelweni ezidinga ama-polyurethane foam aqinile, aguquguqukayo kancane, njengezinhlelo zokuhlala kanye nezokuhlalisa, i-MXC-B20 inikeza umphumela olinganiselayo we-catalyst. Ivumela ukuphola okusheshayo ngenkathi iqinisekisa ukuthi i-foam igcina ukuguquguquka kwayo kanye nokuqina kwayo. Ngokususa isidingo sama-catalyst asekelwe ensimbi, i-MXC-B20 isiza abakhiqizi ukunciphisa ukukhathazeka ngezemvelo kanye nezempilo okuhlobene nezinhlelo ezisekelwe ku-tin, i-lead, noma i-mercury.
5. Ukubumba Umjovo Wokusabela (RIM)I-Reaction Injection Molding (RIM) inqubo ekhethekile esetshenziselwa ukukhiqiza izingxenye ze-polyurethane eziyinkimbinkimbi ezinamandla aphezulu kanye nekhwalithi ephezulu. I-MXC-B20 ilungele ukusetshenziswa kwe-RIM, lapho kudingeka khona ukwelashwa okusheshayo ukunciphisa izikhathi zomjikelezo nokwandisa ukusebenza kahle kokukhiqiza. Amandla e-catalyst okusebenza ngokubambisana nama-amine asheshisa inqubo yokwelapha ngenkathi ekhiqiza izingxenye ezisezingeni eliphezulu neziqinile.
Izinzuzo ze-MXC-B20 ku-HFO Systems
Ukwethulwa kwama-ejenti okufutha i-HFO kube nomthelela omkhulu embonini ye-polyurethane foam, njengoba la ma-ejenti enikeza ithuba lokufudumala komhlaba eliphansi (i-GWP) esikhundleni sama-ejenti okufutha endabuko njenge-HFCs (Hydrofluorocarbons). Ukuhambisana kwe-MXC-B20 nezinhlelo ze-HFO kwenza kube ukukhetha okuhle kakhulu kubakhiqizi abahlose ukunciphisa ukunyathela kwabo kwemvelo. Ngokusebenzisa i-MXC-B20 ezinhlelweni ze-HFO, abakhiqizi bangafinyelela izakhiwo ze-foam eziphakeme ngaphandle kokudela isikhathi sokwelapha noma ukusebenza, konke lokhu ngenkathi belandela imithethonqubo eqinile yemvelo.
