Kumukūʻai maikaʻi o ka mea hana D2000 CAS: 9046-10-0

wehewehe pōkole:

ʻO ka Amine-Terminated Polyether (D2000) kahi papa o nā hui polyolefin me kahi iwi kuamoʻo polyether palupalu, i uhi ʻia e nā hui amine mua a lua paha. No ka mea, ʻo ke kaulahao nui o ka molekala he kaulahao polyether palupalu, a ʻoi aku ka ikaika o ka hydrogen ma ka hopena o ka polyether amine ma mua o ka hydrogen ma ka hopena o ka hui hydroxyl o ka polyether, no laila, hiki i ka polyether amine ke lilo i pani maikaʻi no ka polyether i kekahi mau kaʻina hana mea, a hiki ke hoʻomaikaʻi i ka hana noi o nā mea hou. Hoʻohana nui ʻia ka D2000 i nā mea hoʻoheheʻe injection reactive polyurethane, ka polyurea spraying, nā mea hoʻōla resin epoxy a me nā mea hoʻoheheʻe gasoline.

Nā Waiwai Kemika: ʻO ka Poly(propylene glycol) bis(2-aminopropyl ether) he wai moakaka melemele māmā a ʻaʻohe kala paha ma ka mahana o ka lumi, me nā pono o ka viscosity haʻahaʻa, ke kaomi mahu haʻahaʻa a me ka nui o ka amine mua, a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe e like me ka ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones a me ka wai.
