Mtengo Wabwino Wopanga D2000 CAS: 9046-10-0

kufotokozera mwachidule:

Amine-Terminated Polyether (D2000) ndi gulu la mankhwala a polyolefin okhala ndi msana wofewa wa polyether, wophimbidwa ndi magulu a amine oyambira kapena achiwiri. Chifukwa unyolo waukulu wa molekyulu ndi unyolo wofewa wa polyether, ndipo hydrogen yomwe ili kumapeto kwa polyether amine imagwira ntchito kwambiri kuposa hydrogen yomwe ili kumapeto kwa gulu la hydroxyl la polyether, chifukwa chake, polyether amine ikhoza kukhala m'malo mwa polyether pazinthu zina, ndipo imatha kusintha magwiridwe antchito a zinthu zatsopano. D2000 imagwiritsidwa ntchito kwambiri mu polyurethane reactive injection molding materials, polyurea spraying, epoxy resin curing agents ndi petrol scavengers.

Kapangidwe ka Mankhwala: Poly (propylene glycol) bis (2-aminopropyl ether) ndi madzi opepuka achikasu kapena opanda mtundu pa kutentha kwa chipinda, okhala ndi ubwino wa kukhuthala kochepa, kuthamanga pang'ono kwa nthunzi komanso kuchuluka kwa amine, ndipo amasungunuka mu zosungunulira monga ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones ndi madzi.

Mapulogalamu a D2000

Poly(propylene glycol) bis(2-aminopropyl ether) ili ndi kukana bwino kwa alkali ndi madzi komanso kukana asidi pang'ono. Ma resins a epoxy omwe amachiritsidwa ndi polyetheramines ali ndi mphamvu zamagetsi zabwino. Polyetheramines ili ndi mphamvu zapadera ndipo imagwiritsidwa ntchito pafupifupi mu ntchito zonse za epoxy monga zokutira, zida zophikira m'miphika, zipangizo zomangira, zosakaniza ndi zomatira.
Kukonzekera: kupanga kwa Poly(propylene glycol) bis(2-aminopropyl ether): Choyamba, polyether imalumikizidwa ku gulu la acetoacetate mbali zonse ziwiri ndi dienone kapena kudzera mu ester exchange reaction ya ethyl acetoacetate ndi polyether polyol, kenako polyether yophimbidwa ndi gulu la acetoacetate imasakanizidwa ndi mono-primary amine, alkyl alcohol amine kapena dibasic primary amine kuti ipeze imine compound yokhala ndi viscosity yochepa ndi gulu la aminobutyrate end.
