Ukusetshenziswa kwe-MXC-A1 catalyst ekukhiqizweni kwe-foam ethambile

I-Mingxu Chemicals ingumhlinzeki emkhakheni we-polyurethane catalysts, futhi manje sethula ukuguquguquka kanye nokusetshenziswa okuyisisekelo kwe-polyurethane soft foams kanye nendima ye-I-MXC-A1I-catalyst ekukhiqizweni kwayo. Ama-foam athambile e-polyurethane asetshenziswa kabanzi ngenxa yokuzivumelanisa nezimo kwawo kanye nokunwebeka kwawo, esekela izimboni ezifana nefenisha, izimoto, ezemidlalo, ezokwelapha kanye nokupakisha. Njengoba enezakhiwo ezithuthukisiwe ezifana nokusika, ukuvikela umsindo kanye nokuhlunga, ama-foam athambile ayizinto ezikhethwayo zezinhlelo zokusebenza ezisebenza kahle kakhulu.

Ama-foam athambile e-polyurethane akhiqizwa ukusabela kwamakhemikhali phakathi kwama-diisocyanates nama-polyol, womabili atholakala kakhulu ku-oyela ongahluziwe. Ngaphezu kwalokho, ama-polyol angatholakala kumafutha emvelo avuselelekayo, ahlinzeka ngezinketho zokukhiqiza eziqhubekayo. Uma kuhlanganiswa, i-diisocyanate ne-polyol ziyasabela ukuze zakhe i-foam enesakhiwo se-honeycomb. Lesi sakhiwo sinokucindezelwa, ukunwebeka kanye nezakhiwo ezinhle kakhulu zokubopha, okwenza sibe yindawo ekahle yokusetshenziswa efenisha, imibhede, izihlalo zezimoto, imishini yezemidlalo, imishini yezokwelapha, ukupakisha, izicathulo kanye noMATSHI wekhaphethi. Isakhiwo se-foam ethambile ye-polyurethane siphinde sithuthukise izakhiwo zokuvimbela umsindo kanye nokuhlunga, sandisa kakhulu ukusebenza kwaso emikhakheni eminingi.

Isihluthulelo sokufinyelela ikhwalithi nesakhiwo se-foam esizinzile ukusetshenziswa kwama-catalyst athile kanye nezithasiselo. I-catalyst yethu ye-MXC-A1, ebizwa ngokuthiI-BDMAEE(Inombolo ye-CAS: 3033-62-3) noma i-N,N,N',N' -tetramethyl-2,2′ -oxybis (i-ethylamine), iyisikhuthazi se-amine esisebenza kakhulu, esisetshenziswa kakhulu ekukhiqizweni kwemikhiqizo ye-foam eguquguqukayo, ikakhulukazi ekukhiqizweni kwemikhiqizo ye-RIM ephindaphindayo ephezulu. I-polyurethane foam yenziwa ukusabela kwe-diisocyanate kanye ne-polyol. Lolu ketshezi olungenambala kuya koluphuzi kancane lukhuthaza ukusabela kwe-urea (water-isocyanate) kuma-polyurethane foam athambile futhi aqinile, okuhlinzeka ngomsebenzi wokwenza izinto zibe lula kanye nokukhetha ngesikhathi senqubo yokwenza i-foam.

Izakhiwo eziyingqayizivele ze-MXC-A1 ziyenza ifaneleke ukukhiqiza cishe zonke izinhlobo ze-foam eguquguqukayo, ikakhulukazi imikhiqizo ephindaphindayo ephezulu kanye nezicelo ze-Reaction Injection Molding (RIM). Ngokushintsha usayizi webhamuza ngesikhathi sokusabela phakathi kwama-polyol nama-isocyanates, ama-catalyst e-amine nama-surfactants avumela ukwenza ngokwezifiso ubuningi be-foam kanye nokuqina. Ezinye izithasiselo ezifana ne-flame retardants kanye nama-bacteriostatic agents zithuthukisa kakhulu ububanzi bokusetshenziswa kwe-foam, ikakhulukazi emkhakheni wezindiza, wezimoto, wangaphandle, kanye nowasolwandle.

Nge-catalyst yethu ye-MXC-A1, abakhiqizi be-foam abaguquguqukayo bangafeza ukukhiqizwa okuphumelelayo, ukuhambisana kwe-foam kwekhwalithi ephezulu kanye nokwehlukahluka kokusetshenziswa. Ukuze ufunde kabanzi mayelana ne-MXC-A1 nezinye izinto ezithuthukisayo, sicela usithinte ukuze uthole ukuthi izinto zethu ezithuthukisayo zingahlangabezana kanjani nezidingo zakho zokukhiqiza i-foam eguquguqukayo ye-polyurethane.
