I-Methylenediphenyl disocyanate(CAS#26447-40-5)
Izimpawu Eziyingozi | I-Xn - Iyingozi |
Amakhodi Engozi | R20 – Kuyingozi ngokuhogela umoya R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R42/43 - Ingabangela ukuzwela ngokuhogela umoya nangokuthinta isikhumba. |
Incazelo Yokuphepha | S23 – Ungawuphefumuli umhwamuko. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |
Ama-ID e-UN | I-UN 2811 |
Isingeniso
I-Xylene disocyanate.
Izici: I-TDI iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elimnandi elinamandla. Ingancibilika kuzincibilikisi zemvelo futhi ihlangane nezinto eziningi eziphilayo.
Ukusetshenziswa: I-TDI isetshenziswa kakhulu njengempahla eluhlaza ye-polyurethane, engasetshenziswa ukukhiqiza igwebu le-polyurethane, i-polyurethane elastomer kanye nama-coatings, izinto zokunamathisela, njll. .
Indlela yokulungiselela: I-TDI ngokuvamile ilungiswa ngokusabela kwexylene ne-ammonium bicarbonate ezingeni lokushisa eliphezulu. Izimo ezithile zokusabela kanye nokukhethwa kwe-catalyst kungathinta ubumsulwa kanye nesivuno somkhiqizo.
Ulwazi Lokuphepha: I-TDI yinto eyingozi ecunulayo futhi igceme esikhumbeni, emehlweni nasemgudwini wokuphefumula. Ukuchayeka isikhathi eside noma ukuchayeka emananini amakhulu kungabangela ukulimala kokuphefumula, ukungezwani komzimba, nokuvuvukala kwesikhumba. Uma usebenzisa i-TDI, kufanele kuthathwe izinyathelo zokuphepha ezifanele, njengokugqoka izingubo zamehlo ezivikelayo, amagilavu kanye nezinsimbi zokuphefumula. Lapho ugcina futhi uphatha i-TDI, gwema ukuthintana nemithombo yomlilo futhi usebenze endaweni engenawo umoya. Emkhiqizweni wezimboni kusetshenziswa i-TDI, izinqubo nemithethonqubo efanele yokusebenza kokuphepha kudingeka kulandelwe ngokuqinile.
