DDI (Dimeryl Diisocyanate)
DDI (ʻO Dimeryl Diisocyanate)
| Huahana: | Dimeryl diisocyanate（DDI 1410） | Helu CAS: | 68239-06-5 |
| ʻAno molekala: | C36H66N2O2 | EINECS: | 269-419-6 |
ʻO ka mālama ʻana a me ka mālama ʻana: E pani paʻa i ka pahu i ka wā e hoʻohana ʻole ai.HALE KUAI MA WAHI MALOO.
ʻO ka Dimeryl diisocyanate (DDI) he aliphatic kū hoʻokahi (dimer fatty acid diisocyanate) diisocyanate hiki ke hoʻohana ʻia me nā pūhui i loaʻa i ka hydrogen ikaika e hoʻomākaukau ai i nā derivatives haʻahaʻa molecular weight a i ʻole polymers kūikawā.
ʻO DDI kahi pūhui kaulahao lōʻihi me kahi kaulahao nui o nā ʻakika momona dimeric me 36 mau kalapona kalapona.Hāʻawi kēia ʻano iwi kuamoʻo i ka DDI ʻoi aku ka maʻalahi, ke kūpaʻa wai a me ka haʻahaʻa haʻahaʻa ma luna o nā isocyanates aliphatic.
He wai viscosity haʻahaʻa ka DDI i hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe polar a i ʻole nonpolar.

Nā memo
1) ʻO nā ʻikepili ʻenehana āpau i hōʻike ʻia ma luna nei no kāu kuhikuhi.
2) Hoʻokipa ʻia nā kikoʻī ʻē aʻe no ke kūkākūkā hou aku.
Hiki ke hoʻohana ʻia ka DDI i loko o ka rocket propellant paʻa, ka hoʻopau lole, ka pepa, ka ʻili a me ka pale lole, ka mālama mālama lāʻau, ka ipu uila a me ka hoʻomākaukau ʻana i nā waiwai kūikawā o ka polyurethane (urea) elastomers, adhesive and sealant, etc.
Loaʻa i ka DDI nā waiwai haʻahaʻa, ʻaʻohe melemele, hoʻoheheʻe i ka hapa nui o nā mea hoʻoheheʻe organik, haʻahaʻa wai haʻahaʻa a haʻahaʻa viscosity.
Ma ka ʻoihana Fabric, hōʻike ʻo DDI i kahi manaʻo noi maikaʻi loa i ka wai-repellent a me nā waiwai palupalu i nā lole.ʻAʻole hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā emulsion aqueous paʻa.Hiki i ka DDI ke hoʻomaikaʻi i ka hopena o ka wai-repellent a me ka aila-repellent no nā lole fluorinated.Ke hoʻohana pū ʻia, hiki i ka DDI ke hoʻomaikaʻi nui i ka wai-repellent a me ka aila-repellent waiwai o nā lole.
ʻO DDI, i hoʻomākaukau ʻia mai ka dimer fatty acids, he ʻano ʻōmaʻomaʻo maʻamau, bio-renewable isocyanate.Ke hoʻohālikelike ʻia me ka honua isocyanate TDI, MDI, HDI a me IPDI, ʻaʻohe mea ʻawaʻawa a hoʻoulu ʻole ʻo DDI.
Ka lawelawe ʻana: Hōʻalo i ka pili ʻana me ka wai.E hōʻoia i ka ea maikaʻi ma kahi hana.
E mālama: E mālama i loko o nā pahu paʻa paʻa, maloʻo a maloʻo.
ʻIkepili kaʻahele: ʻaʻole i hoʻoponopono ʻia ma ke ʻano he mea weliweli.
