DDI (Dimeryl Diisocyanate)

Huahana: ʻO Dimeryl diisocyanateI DDI 1410 CAS No. 68239-06-5
Hakakino haʻilula : C36H66N2O2 ʻEINECS : 269-419-6

Ka mālama ʻana a me ka mālama ʻana i nā hana: KEEP CONTAINER PUPUKU Pani ʻia ke ʻōlelo ʻole e hoʻohana. HALEKUAI MA KAHI WAHI PULE.

ʻO Dimeryl diisocyanate (DDI) kahi aliphatic kū hoʻokahi (dimer fatty acid diisocyanate) diisocyanate i hiki ke hoʻohana ʻia me nā pūhui i piha i ka hydrogen e hoʻomākaukau i nā mea kaumaha kaumaha mole mole a i ʻole nā ​​polymers kūikawā.
He hui kaulahao lōʻihi ʻo DDI me kahi kaulahao nui o dimeric fatty acid me 36 mau ʻāpana kalapona. Hāʻawi kēia iwi kuamoʻo i ka DDI ʻoi aku ka maʻalahi, ka wai kūpaʻa a me ka hoʻohaʻahaʻa haʻahaʻa ma luna o nā isocyanates aliphatic.
He wai haʻahaʻa viscosity ʻo DDI i maʻalahi ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe ʻia nā polar a i ʻole nā ​​nonpolar.

Nā memo

1) nā ʻike ʻenehana āpau i hōʻike ʻia ma luna aʻe nei no kāu kūmole.
2) ʻoluʻolu e hōʻike i kahi kikoʻī no kahi kūkā hou.
Hiki ke hoʻohana ʻia ka DDI i ka propellant rocket paʻa, hoʻopau lole, pepa, ʻili a me ka pale ʻana i ka pale, mālama lāʻau mālama lāʻau, ipu uila a me ka hoʻomākaukau ʻana i nā waiwai kūikawā o polyurethane (urea) elastomers, adhesive and sealant, etc.
He waiwai ʻo DDI o ka haʻahaʻa, ʻaʻohe melemele, hoʻoheheʻe i ka hapa nui o nā mea hiki ke hoʻōla, haʻahaʻa i ka wai a me ka viscosity haʻahaʻa.
I ka ʻāpana lole, hōʻike ʻo DDI i kahi prospect noi maikaʻi loa i ka wai-hoʻopale wai a me nā mea palupalu i nā lole. ʻOi aku ka maʻalahi o ka wai ma mua o nā isocyanates a hiki ke hoʻohana ʻia e hoʻomākaukau i nā emulsion wai paʻa. Hiki i ka DDI ke hoʻomaikaʻi i ka hopena o ka wai-wai a me ka aila-aila no nā lole fluorinated. Ke hoʻohana ʻia i ka hui ʻana, hiki i ka DDI ke hoʻomaikaʻi maikaʻi i ka wai-hoʻopale wai a me nā waiwai aila-aila o nā lole.
ʻO DDI, i hoʻomākaukau ʻia mai nā dim momona momona, he ʻōmaʻomaʻo maʻamau, ʻano isocyanate bio-hou. Ke hoʻohālikelike ʻia me TDI isocyanate ākea, MDI, HDI a me IPDI, non-ʻawahia a non-stimulate ka DDI.
Lawelawe lima: E hōʻalo i ka pili me ka wai. E hōʻoia i ka ea maikaʻi ma kahi hana.
Papaa: Hale kūʻai i loko o nā ipu paʻa paʻa, ʻoluʻolu a maloʻo.
Ka ʻike halihali: ʻaʻole kau ʻia ma ke ʻano he mea weliweli.
