Iikhatalyst zePolyurethane, njenge-MXS-6 (DC-193), zibalulekile ekuvelisweni kwee-soli ze-polyurethane (PU), isiseko seshishini lezihlangu. Ezi catalysts, kuquka ii-surfactants ze-silicone ezisemgangathweni weshishini, zibalulekile ekudaleni izicelo ze-polyurethane foam eqinileyo, ingakumbi ekuvelisweni kwezihlangu. Zidlala indima ebalulekileyo ekuphuculeni iimpawu zee-soli ze-PU, zizenza zilungele iintlobo ezahlukeneyo zezihlangu kuquka izihlangu eziqhelekileyo, izihlangu zokhuseleko, kunye nezihlangu zemidlalo.
Umsebenzi oyintloko wee-polyurethane catalysts kukukhawulezisa impendulo yamakhemikhali phakathi kwee-isocyanates kunye nee-polyols, ezenza i-polyurethane. Le mpendulo ibalulekile ekudaleni isakhiwo se-foam see-PU soles, isinika iipropati ezikhethekileyo ezifana nokuqina, ukuthamba, kunye nokufunxwa komothuko. I-MXS-6 (DC-193), njenge-silicone surfactant, inceda ukuzinzisa isakhiwo se-foam, iqinisekisa umgangatho ohambelanayo kunye nokusebenza kwee-PU soles.
Kwizihlangu ezikhululekileyo, izihlangu zepolyurethane zinika intuthuzelo nokuguquguquka okungenakuthelekiswa nanto. Indima ye-catalyst ekuqinisekiseni ulwakhiwo lwe-foam olugudileyo noluhambelanayo iguqulela kwizihlangu ezibonelela ngokuqina okufana nolwesikhumba kunye nomphezulu ogudileyo. Oku kubangela izihlangu ezingakhululekanga nje kuphela ekunxibeni ixesha elide kodwa nezinomtsalane ngobuhle, ezihambelana nesitayile kunye neemfuno zokukhululeka zabanxibi bezihlangu ezikhululekileyo.
Kwiibhutsi zokhuseleko, ukuqina kunye neempawu zokufunxa ukubetheka kwee-polyurethane soli zibalulekile. Ii-catalysts ziqinisekisa ukuba ii-PU soli zinesakhiwo se-foam esiqinileyo esikwaziyo ukumelana neemeko ezinzima kunye nokukhusela iinyawo zomntu onxibe. Amandla okufunxa ukubetheka anikezelwa zii-catalysts anceda ekunciphiseni impembelelo ezinyaweni nakwiindawo ezidityanisiweyo, nto leyo ebaluleke kakhulu kubantu abasebenza kwiindawo ezixineneyo. Olu khuseleko, kunye nokuqina kwee-PU solids, lwenza ii-safety boots zithembeke kwaye zihlale ixesha elide.
Izihlangu zemidlalo zifuna iimpawu zokusebenza ezigqwesileyo, eziphuculwa kakhulu zii-polyurethane catalysts. Ukuguquguquka kunye nokuthomalalisa okunikezelwa zii-PU soles kubalulekile kwizihlangu zemidlalo, zibonelela ngenkxaso engcono kwaye zinciphisa impembelelo ezinyaweni ngexesha lemisebenzi enamandla kakhulu.I-MXS-6 (DC-193)qinisekisa ukuba iintende zigcina ulwakhiwo lwazo kunye nokusebenza kwazo, nokuba phantsi kweemeko ezinzima zokusetyenziswa kwezemidlalo.
Ngaphezu koko, izihlangu ze-polyurethane ezenziwe ngezi catalysts zikhaphukhaphu, zongeza intuthuzelo nokusebenza kakuhle kwezihlangu. Olu hlobo lukhaphukhaphu luluncedo kuzo zonke iintlobo zezihlangu, ukusuka kwizihlangu eziqhelekileyo ukuya kwizihlangu zemidlalo nezokhuseleko, kunciphisa ukudinwa nokuphucula amava okunxiba ngokubanzi.
Ngamafutshane, ii-catalysts ze-polyurethane ezifana ne-MXS-6 (DC-193) zibalulekile ekuvelisweni kwee-PU soles ezisemgangathweni ophezulu ezisetyenziswa kwiintlobo ngeentlobo zezihlangu. Ziqinisekisa ukuqina, intuthuzelo, ukufunxwa komothuko, kunye neempawu ezilula zezihlangu, zihlangabezana neemfuno ezahlukeneyo zabavelisi bezihlangu kunye nabathengi. Ukusetyenziswa kwezi catalysts kwinkqubo yemveliso kukhokelela kwiimveliso zezihlangu eziphezulu ezilungele abanxibe nje, abadlali, kunye nabantu abafuna izihlangu zokhuseleko, nto leyo eqinisa isikhundla se-polyurethane njengezinto ezikhethwayo kushishino lwezihlangu.
