DDI (Dimeryl Diisocyanate)

Oloa : Dimeryl diisocyanateI DDI 1410) CAS Nu. 68239-06-5
Fuafua Molecular : C36H66N2O2 EINECS : 269-419-6

Taulimaina ma le Teuina o Lapataiga: TAUSI MAUA MAUA TUPE MAUA PEPA FAI. Faleoloa I LE Nofoaga Pogisa.

Dimeryl diisocyanate (DDI) o se aliphatic tulaga ese (dimer fatty acid diisocyanate) diisocyanate e mafai ona faʻaaogaina ma vailaʻau o loʻo iai le hydrogen e sauniuni ai le maualalo o le molimoli mamafa poʻo ni vailaʻau faʻapitoa.
O le DDI o se filifili uʻamea umi ma le filifili autu o dimeric fatty acid ma le 36 carbon atoms. Lenei fausaga pito i tua tuʻuina atu DDI sili fetuʻunaʻi, vai tetee ma maualalo oona i luga o isi alphatic isocyanates.
DDI o se maualalo viscosity suavaia e faigofie ona soluble i tele polar poʻo nonpolar solvents.

Faamatalaga

1) uma faʻamatalaga faʻapitoa faʻailoa mai luga e mo lau faʻasino.
2) o isi faʻamatalaga faʻapitoa e talia lelei mo nisi talanoaga.
DDI mafai ona faʻaaogaina i le mausali faʻatosina folau, ie faʻamaeʻaina, pepa, paʻu ma ie teuteuina, laupapa faʻasao le togafiti, eletise faʻapipiʻiina ma sauniuniga o faʻapitoa meatotino o polyurethane (urea) elastomers, pipiʻi ma faʻamau faʻamau, ma isi
DDI ei ai meatotino o laʻititi oona, leai samasama, faʻateʻesea i le tele o vailaʻau soli, maualalo vai maaleale ma maualalo le ogatotonu.
I pisinisi ie, DDI faʻaalia se sili lelei faʻamoemoega faʻamoemoega i le vai-repeleti ma faʻamaluluina meatotino i ie. E tau leiloa ile vai nai lo le manogi isocyanates ma e mafai ona faʻaaoga e sauniuni ai le faʻamalosi suavai. E mafai e le DDI ona faʻaleleia le aafiaga o le vai-repeleti ma le suauʻu-repeleti mo ie flororated. A faʻaogaina faʻatasi, e mafai e le DDI ona faʻaleleia atili le suavai-faʻafouina ma le suauʻu-repeleti meatotino o ie.
O le DDI, na saunia mai le laʻititi o gaʻo gaʻo, o se ituaiga lanumeamata, ituaiga o isocyanate e mafai ona toe faʻafouina. Faʻatusatusa i le lautele isocyanate TDI, MDI, HDI ma IPDI, DDI e le oona ma e le faʻaosofia.
Taulimaina: Aloese mai le faʻafesoʻotaʻi ma le vai. Faamautinoa le lelei ea i le falefaigaluega.
Teuina: Teu i pusa tapuni tapuni, malulu ma mago.
Faʻamatalaga femalagaaʻi: le faʻatonutonuina o se mea matautia.
