Mea Hana Maikaʻi Kumu D2000 CAS: 9046-10-0

wehewehe pōkole:

ʻO Amine-TerminatedPolyether (D2000) he papa o nā pūhui polyolefin me ka iwi kuamoʻo polyether palupalu, i uhi ʻia e nā hui amine mua a lua paha. No ka mea, ʻo ke kaulahao nui o ka mole he kaulahao polyether palupalu, a ʻoi aku ka ikaika o ka hydrogen ma ka terminal o polyether amine ma mua o ka hydrogen ma ka pūʻulu hydroxyl terminal o polyether, no laila, hiki i ka polyether amine ke lilo i mea pani maikaʻi no ka polyether i kekahi mau kaʻina hana, a hiki ke hoʻomaikaʻi i ka hana noi o nā mea hou. Hoʻohana nui ʻia ʻo D2000 i ka polyurethane reactive injection molding material, polyurea spraying, epoxy resin curing agents and gasoline scavengers.

Nā Waiwai Kemika: ʻO ka poly(propylene glycol) bis(2-aminopropyl ether) he wai māmā melemele a ʻaʻole waihoʻoluʻu paha i ka lumi wela, me ka maikaʻi o ka viscosity haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka amine kiʻekiʻe, a hiki ke hoʻoheheʻe ʻia i nā solvents e like me ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers a me ka wai.
