| Umkhiqizo: | I-Dimeryl diisocyanateI-DDI 1410） | I-CAS No. | 68239-06-5 |
| Ifomula Yamamolekhula: | C36H66N2O2 | I-EINECS: | 269-419-6 |
Izinyathelo Zokuqapha Ukuphatha Nokugcina: QHUBEKA ISITSITSHI SIVALIWE NGOKUQINILE UMA UNGASETSHENZISIWE. ISITOLO ENDAWENI EYOMILE.
I-Dimeryl diisocyanate (i-DDI) iyi-aliphatic eyingqayizivele (i-dimer fatty acid diisocyanate) i-diisocyanate engasetshenziswa ngamakhemikhali aqukethe i-hydrogen esebenzayo ukulungiselela okuphuma kwesisindo samangqamuzana noma ama-polymers akhethekile.
I-DDI iyinhlanganisela yamaketanga amade enochungechunge olukhulu lwama-acid anamafutha enama-athomu angama-36 ekhabhoni. Lesi sakhiwo somgogodla sinikeza i-DDI ukuguquguquka okuphezulu, ukumelana kwamanzi nobuthi obuphansi kunamanye ama-isocyanate e-aliphatic.
I-DDI iwuketshezi oluphansi lwe-viscosity oluncibilika kalula kuma-solvents amaningi we-polar noma nonpolar.

Amanothi
1) yonke imininingwane yezobuchwepheshe ekhonjiswe ngenhla yenzelwe inkomba yakho.
2) okunye ukucaciswa kwamukelekile engxoxweni eqhubekayo.
I-DDI ingasetshenziswa ku-rocket propellant eqinile, ekuqedeni indwangu, iphepha, isikhumba kanye nokuxosha izindwangu, ukwelashwa okulondolozwa ngokhuni, ukubumba ugesi nokulungiselela izakhiwo ezikhethekile ze-elastomers ze-polyurethane (urea), i-adhesive ne-sealant, njll.
I-DDI inezakhiwo ezinobuthi obuphansi, ayikho i-yellowing, iyancibilika kuma-solvents amaningi we-organic, amanzi aphansi azwelayo kanye ne-viscosity ephansi.
Embonini Yezindwangu, i-DDI ikhombisa ithemba elihle kakhulu lokufaka isicelo ezindaweni ezixosha amanzi nezithambisa izindwangu. Ayizweli kangako emanzini kunama-isocyanate anamakha futhi ingasetshenziselwa ukulungiselela ama-emulsion aqueous ezinzile. I-DDI ingathuthukisa umthelela wokuxosha amanzi nowokuxosha uwoyela ngezindwangu ezi-fluorinated. Uma isetshenziswa inhlanganisela, i-DDI ingathuthukisa ngokuphawulekayo izindwangu ezixosha amanzi neziphonsa uwoyela.
I-DDI, elungiselelwe kusuka ku-dimer fatty acids, iyinhlobo ejwayelekile eluhlaza, evuselelekayo ye-isocyanate. Uma kuqhathaniswa ne-isocyanate TDI yendawo yonke, i-MDI, i-HDI ne-IPDI, i-DDI ayinabuthi futhi ayikhuthazi.
Ukuphatha: Gwema ukuthintana namanzi. Qiniseka ukuthi kungena umoya omncane emsebenzini.
Isitoreji: Gcina ezitsheni ezivalwe ngci, kupholile futhi komile.
Imininingwane yokuhamba: ayilawulwa njengezinto ezinobungozi.
