| Usoro ihe omimi: | C36H66N2O2 | EINECS: | 269-419-6 |
Ijikwa na Nchekwa kpachara anya: DỊ KA emechi akpa nke ọma mgbe ejighi ya.Echekwaa n'ebe kpọrọ nkụ.
Dimeryl diisocyanate (DDI) bụ aliphatic pụrụ iche (dimer fatty acid diisocyanate) diisocyanate nke enwere ike iji ya na ogige nwere hydrogen na-arụ ọrụ iji kwadebe ihe mgbapụta dị ala ma ọ bụ polymers pụrụ iche.
DDI bụ ngwakọta yinye ogologo nwere nnukwu yinye dimeric fatty acids nwere carbon carbon 36.Ọdịdị ọkpụkpụ azụ a na-enye DDI mgbanwe dị elu, nguzogide mmiri na nsí dị ala karịa isocyanates aliphatic ndị ọzọ.
DDI bụ mmiri mmiri viscosity dị ala nke na-agbaze ngwa ngwa n'ọtụtụ ihe mgbaze pola ma ọ bụ ndị na-abụghị polar.

Enwere ike iji DDI mee ihe na rocket propellant siri ike, ihe na-emecha akwa, akwụkwọ, akpụkpọ anụ na ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-edozi osisi, ihe ọkụkụ eletrik na nkwadebe nke ihe pụrụ iche nke polyurethane (urea) elastomers, nrapado na sealant, wdg.
DDI nwere akụrụngwa nke nsi dị ala, enweghị odo odo, na-agbari n'ọtụtụ ihe mgbaze organic, obere mmiri nwere mmetụta na viscosity dị ala.
N'ime ụlọ ọrụ akwa akwa, DDI na-egosi atụmanya ngwa dị mma na mmiri na-egbochi mmiri na ihe na-eme ka ọ dị nro na akwa ákwà.Ọ naghị enwe mmetụta na mmiri karịa aromatic isocyanates ma enwere ike iji ya dozie emulsions aqueous kwụsiri ike.DDI nwere ike imeziwanye mmetụta nke mmiri na-egbochi mmiri na mmanụ maka akwa fluorinated.Mgbe ejiri ya mee ihe, DDI nwere ike imeziwanye ihe ndị na-eme ka mmiri na mmanụ na-eme ka akwa dị mma.
DDI, nke a kwadebere site na dimer fatty acids, bụ ụdị akwụkwọ ndụ akwụkwọ ndụ na-ahụkarị, ụdị isocyanate dị iche iche na-emegharịghachi.Tụnyere eluigwe na ala isocyanate TDI, MDI, HDI na IPDI, DDI adịghị egbu egbu na-adịghị na-akpali akpali.
Ijikwa: Zere kọntaktị na mmiri.Gbaa mbọ hụ na ikuku ikuku dị mma n'ebe ọrụ.
