Ukusetyenziswa kweeMveliso
I-HQEE yi-symmetrical aromamatic diol chain extender. Inokuphucula ukuqina, ukuqina, iipropathi zokuqina kwi-MDI-polyurethane elastomers. I-HQEE/MDI yi-PU elastomer series parallels MOCA/TDI. Iimveliso ezigqityiweyo njenge: izitywina ze-oyile, i-forklift, i-conveyor belt, i-hydraulic cylinder seals kunye nezinye iimveliso ze-PU ezininzi.
I-elastomers ze-LCU zifuna amacandelo amabini omgaqo: i-prepolymer epheliswe ngamaqela e-isocyanate asebenzayo kunye ne-difunctional esebenzayo ye-hydrogen-terminated chain extender. I-Prepolymer yimveliso esekelwe kwimpendulo ye-polyester okanye i-polyether ene-isocyanate (TDI, MDI, ADI). Ichain extender idla ngokuba yitsheyini emfutshane yediamine okanye idiol. Iiprepolymers ze-MDI zihlala zongezwa ngee-diols.
Ukupakishwa kunye noGcino
Umqulu:
25kg/igubu lebhokisi okanye njengeemfuno zakho.
Phawula: Ukwakhiwa kweekhemikhali kunye nobukhulu bunokulungiswa ngokweemfuno zabathengi
Ugcino:
Gcina uvale ngokuqinileyo. I-HQEE i-hygroscopic kwaye iya kutshintsha umbala phantsi kokukhanya kwelanga. Gcina uvaliwe kwaye ugcine kwindawo engenamoya. Zigcine kude nokufuma nokukhanya kwelanga
Ukhuseleko loKhuseleko
Izilumkiso zokuphatha ngokukhuselekileyo
Ukuphatha kwindawo engena umoya. Nxiba iimpahla ezifanelekileyo zokuzikhusela. Kuphephe ukudibana nolusu namehlo. Kuphephe ukubunjwa kothuli kunye ne-aerosols. Sebenzisa izixhobo ezingatshisiyo. Thintela umlilo obangelwa ngumphunga wokukhupha i-electrostatic.
