| imveliso: | I-Dimeryl diisocyanate(DDI 1410) | Inombolo yeCAS: | 68239-06-5 |
| Ifomula yemolekyuli: | I-C36H66N2O2 | EINECS: | 269-419-6 |
Ukuphatha kunye nokuGcina Imiqathango: GCINA ISIXHOBO SIVALWE KAKHULU XA UNGASETYENZISIWE.UKUGCINA KWINDAWO EYOMILEYO.
I-Dimeryl diisocyanate (DDI) i-aliphatic ekhethekileyo (i-dimer fatty acid diisocyanate) i-diisocyanate enokusetyenziswa kunye neekhompawundi eziqukethe i-hydrogen esebenzayo ukulungiselela i-derivatives ephantsi ye-molecular weight or polymers ekhethekileyo.
I-DDI yikhonkco elide elinekhonkco eliphambili le-dimeric fatty acids kunye ne-36 athom ye-carbon.Esi sakhiwo somqolo sinika i-DDI ukuguquguquka okuphezulu, ukuxhathisa kwamanzi kunye netyhefu ephantsi kwezinye i-aliphatic isocyanates.
I-DDI lulwelo olusezantsi lwe-viscosity olunyibilika ngokulula kuninzi lwezinyibilikisi ezimhlophe okanye ezingezizo ezipolar.

Amanqaku
I-1) yonke idatha yobugcisa eboniswe ngasentla yereferensi yakho.
2) enye ingcaciso yamkelekile kwingxoxo eqhubekayo.
I-DDI ingasetyenziselwa kwi-rocket propellant eqinile, ukugqiba ilaphu, iphepha, isikhumba kunye ne-repellent yelaphu, unyango lokukhusela umthi, ukubumba kombane kunye nokulungiswa kweempawu ezikhethekileyo ze-polyurethane (urea) elastomers, i-adhesive kunye ne-sealant, njl.
I-DDI ineempawu zetyhefu ephantsi, akukho tyheli, inyibilika kwi-solvents ezininzi ze-organic, ubuthathaka bamanzi aphantsi kunye ne-viscosity ephantsi.
Kushishino lweFabric, i-DDI ibonisa i-app egqwesileyo ye-prospect in the water-repent and softening properties to fabrics.Ayinabungozi kangako emanzini kune-isocyanates enevumba elimnandi kwaye ingasetyenziselwa ukulungisa i-emulsions enamanzi azinzileyo.I-DDI inokuphucula isiphumo sokugxotha amanzi kunye ne-oyile yokugxotha amalaphu e-fluorinated.Xa isetyenziswe ngokudibeneyo, i-DDI inokuphucula ngokubonakalayo iipropati zokugxotha amanzi kunye neoli ye-oyile yempahla.
I-DDI, elungiselelwe ukusuka kwi-dimer fatty acids, luhlobo oluqhelekileyo lwe-isocyanate eluhlaza, ehlaziyiweyo ye-bio.Xa kuthelekiswa ne-Universal isocyanate TDI, MDI, HDI kunye ne-IPDI, i-DDI ayinayo inetyhefu kwaye ayikhuthazi.
Ukuphatha: Kuphephe ukudibana namanzi.Qinisekisa ukungena komoya kakuhle emsebenzini.
Ukugcina: Gcina kwizikhongozeli ezivaliweyo, zipholile kwaye zome.
Ulwazi lwezothutho: alulawulwa njengesixhobo esiyingozi.
