I-polyurethane elastomer uhlobo lwezinto ezisetshenziswa kabanzi, inokuguquguquka okuhle, ukuqina kanye nokumelana nokuguguleka, ngakho-ke isetshenziswa kabanzi kuzo zonke izindlela zokuphila. Esinye sezici ezibalulekile ekukhiqizweni kwama-polyurethane elastomer ukusetshenziswa kwama-catalyst asheshisa ukusabela kwamakhemikhali ngesikhathi sokwakheka kwezinto zokugcina. Lawa ma-catalyst abalulekile ekulawuleni inqubo ye-polymerization, ukuqinisekisa ukuthi izakhiwo ezifiselekayo ze-elastomer ziyafezwa. Phakathi kwama-catalyst ahlukahlukene atholakalayo, i-MXC-A33 inokwakheka okuhlukile okungasetshenziswa ezinhlobonhlobo zama-polyurethane foams nama-elastomers.
KuyiniI-MXC-A33?
I-MXC-A33 iyi-catalyst ye-polyurethane ethuthukisa ukusabela phakathi kwama-polyol nama-isocyanates, okuyizinto eziyinhloko zezinto ze-polyurethane. I-catalyst yakhiwe yi-33% TEDA (triethylene diamine) kanye ne-67% DPG (i-monoconjugated dipropylene glycol). Lokhu kwakheka okukhethekile kunikeza ukusebenza okuhle kakhulu ekukhiqizweni kwama-polyurethane foams nama-elastomers.
- I-TEDA (i-Triethylenediamine): I-catalyst ye-tertiary amine esebenza kahle kakhulu ekhuthaza ukusabela kwe-gelling phakathi kwamaqembu e-hydroxyl kanye ne-isocyanate.
- I-DPG (i-Monoconjugated Dipropylene Glycol): Isinyibilikisi esisiza ukunciphisa ukujiya nokuthuthukisa ukuxubana kwezinto, okuqinisekisa inqubo yokusabela ebushelelezi.
Ukusetshenziswa ku-Polyurethane Elastomers
I-MXC-A33 isetshenziswa kabanzi ekukhiqizweni kwama-elastomer e-polyurethane ngenxa yomphumela wayo olinganiselayo we-catalytic, oqinisekisa ukuthi ukusabela kwe-polymerization kwenzeka ngesivinini esilawulwayo. Lokhu kusebenza okulawulwayo kubalulekile ekukhiqizweni kwama-elastomer anezakhiwo ezifunwayo zemishini njengokuqina, amandla okudonsa kanye nokumelana nokuguguleka.
I-catalyst ikhuthaza ukwakheka kwezakhiwo ze-polymer ezixhumene ngokulinganayo, ezingahlangabezana nokusebenza kwama-elastomer ekusetshenzisweni okudingakalayo. Ama-elastomer e-polyurethane enziwe nge-MXC-A33 avame ukusetshenziswa ezingxenyeni zezimoto, kuma-roller ezimboni, kanye nasezintini ezisebenza kahle kakhulu, okubeka izidingo eziphezulu ekuqineni nasekuqineni kwawo.
Isiphetho
Ukusetshenziswa kweama-catalyst e-polyurethanenjenge-MXC-A33 ekukhiqizweni kwe-elastomer kuyisici esibalulekile ekuqinisekiseni ukusebenza nokuthembeka kwezinto ezibonakalayo. Inhlanganisela yayo eyingqayizivele ye-TEDA ne-DPG iyenza isebenze kahle kakhulu kokubili ukusetshenziswa kwe-foam kanye ne-elastomer, okwenza abakhiqizi bakwazi ukukhiqiza imikhiqizo esezingeni eliphezulu nehlala isikhathi eside yezimboni ezahlukahlukene.
