Ama-catalyst e-polyurethane, njenge-MXS-6 (DC-193), zibalulekile ekukhiqizweni kwezithende ze-polyurethane (PU), okuyitshe lesisekelo embonini yezicathulo. Lezi zi-catalyst, okuhlanganisa ne-silicone surfactants ezijwayelekile embonini, zibalulekile ekudaleni izinhlelo zokusebenza ze-polyurethane foam eziqinile, ikakhulukazi ekukhiqizweni kwezicathulo. Zidlala indima ebalulekile ekuthuthukiseni izakhiwo zezithende ze-PU, zizenze zifaneleke ezinhlotsheni ezahlukene zezicathulo okuhlanganisa izicathulo ezivamile, amabhuzu okuphepha, kanye nezicathulo zemidlalo.
Umsebenzi oyinhloko wama-catalyst e-polyurethane ukusheshisa ukusabela kwamakhemikhali phakathi kwama-isocyanates nama-polyol, akha i-polyurethane. Lokhu kusabela kubalulekile ekudaleni isakhiwo se-foam sama-PU soles, kuwanika izakhiwo ezihlukile njengokuqina, ukuguquguquka, kanye nokumuncwa kwe-shock. I-MXS-6 (DC-193), njenge-silicone surfactant, isiza ekuqiniseni isakhiwo se-foam, iqinisekisa ikhwalithi ehambisanayo kanye nokusebenza kwama-PU soles.
Ezicathulweni ezivamile, ama-polyurethane soli anikeza induduzo nokuguquguquka okungenakuqhathaniswa. Indima ye-catalyst ekuqinisekiseni isakhiwo se-foam esibushelelezi nesihambisanayo ihumusha kuma-soli anikeza ukunwebeka okufana nesikhumba kanye nobuso obubushelelezi. Lokhu kuphumela ezicathulweni ezingagcini nje ngokukhululekile ukugqokwa isikhathi eside kodwa futhi ezijabulisa ngobuhle, ezihlangabezana nezidingo zesitayela kanye nenduduzo yabagqoki bezicathulo ezivamile.
Kumabhuthi okuphepha, ukuqina kanye nezimfanelo zokumunca ukushaqeka kwama-polyurethane soli kubalulekile. Ama-catalyst aqinisekisa ukuthi ama-PU soli anesakhiwo se-foam esiqinile esikwazi ukumelana nezimo ezinzima nokuvikela izinyawo zomgqoki. Amandla okumunca ukushaqeka anikezwa ama-catalyst asiza ekunciphiseni umthelela ezinyaweni nasemalungeni, okubaluleke kakhulu kubantu abasebenza ezindaweni ezidinga kakhulu. Lokhu kuvikelwa, kuhlanganiswe nokuqina kwama-PU soli, kwenza amabhuthi okuphepha athembeke futhi ahlala isikhathi eside.
Izicathulo zemidlalo zidinga izici zokusebenza eziphakeme, ezithuthukiswa kakhulu yi-polyurethane catalysts. Ukuguquguquka kanye nokuthungwa okunikezwa yizinyawo ze-PU kubalulekile ezicathulweni zemidlalo, kunikeza ukwesekwa okungcono futhi kunciphisa umthelela ezinyaweni ngesikhathi semisebenzi enamandla kakhulu. Ama-catalysts afanaI-MXS-6 (DC-193)qinisekisa ukuthi amathe agcina isakhiwo nokusebenza kwawo, ngisho nangaphansi kwezimo ezinzima zokusetshenziswa kwezemidlalo.
Ngaphezu kwalokho, izithende ze-polyurethane ezikhiqizwa ngalezi zi-catalyst zilula, okwengeza induduzo nokusebenza kahle kwezicathulo. Lolu hlobo olulula luwusizo kuzo zonke izinhlobo zezicathulo, kusukela ezicathulweni ezivamile kuya kwezemidlalo nezokuphepha, kunciphisa ukukhathala futhi kuthuthukise ulwazi lokugqoka jikelele.
Ngamafuphi, ama-catalyst e-polyurethane afana ne-MXS-6 (DC-193) abalulekile ekukhiqizweni kwama-soli e-PU asezingeni eliphezulu asetshenziswa ezinhlotsheni ezahlukene zezicathulo. Aqinisekisa ukuqina, induduzo, ukumuncwa kokushaqeka, kanye nezakhiwo ezilula zama-soli, okuhlangabezana nezidingo ezahlukahlukene zabakhiqizi bezicathulo nabathengi. Ukusetshenziswa kwala ma-catalyst enqubweni yokukhiqiza kuholela emikhiqizweni yezicathulo engcono kakhulu enakekela abagqoki abavamile, abasubathi, kanye nabantu abadinga izicathulo zokuphepha, okwenza isikhundla se-polyurethane sibe yinto ekhethwayo embonini yezicathulo.
