Utu Pai a te Kaihanga D2000 CAS: 9046-10-0

whakaahuatanga poto:

Ko te Amine-Terminated Polyether (D2000) he akomanga o ngā matū polyolefin me te tuara polyether ngohengohe, e taupokina ana e ngā rōpū amine tuatahi, tuarua rānei. Nā te mea ko te mekameka matua o te ngota he mekameka polyether ngohengohe, ā, he kaha ake te hauwai i te pito o te polyether amine i te hauwai i te pito o te polyether group hydroxyl o te polyether, nō reira, he pai te whakakapinga o te polyether amine mō te polyether i roto i ētahi tukanga rauemi, ā, ka taea te whakapai ake i te mahi tono o ngā rauemi hou. He whānuitia te whakamahinga o te D2000 i roto i ngā rauemi whakarewa werohanga polyurethane tauhohe, te rehu polyurea, ngā kaihoko whakaora kapia epoxy me ngā kaihoroi penehīni.

Ngā Āhuatanga Matū: He wai mārama, he kowhai mārama, he kore tae rānei te Poly(propylene glycol) bis(2-aminopropyl ether) i te pāmahana rūma, he iti te matotoru, he iti te pēhanga kohu, he nui hoki te ihirangi amine tuatahi, ā, ka wairewa i roto i ngā whakarewa pērā i te etanoru, ngā hauwaiwaro aliphatic, ngā hauwaiwaro kakara, ngā ester, ngā ether glycol, ngā ketone me te wai.

Ngā tono o te D2000

He pai te ātete o te Poly(propylene glycol) bis(2-aminopropyl ether) ki te kawakore me te wai, ā, he ātete waikawa ngawari. He pai ngā āhuatanga hiko o ngā kapia epoxy kua whakamaroketia ki ngā polyetheramine. He āhuatanga ahurei ngā polyetheramine, ā, e whakamahia ana i roto i te nuinga o ngā tono epoxy pēnei i ngā paninga, ngā rauemi kohua, ngā rauemi hanga, ngā mea whakahiato me ngā piripiri.
Te Whakarite: Te Hanganga o te Poly(propylene glycol) bis(2-aminopropyl ether): Tuatahi, ka honoa te polyether ki te rōpū acetoacetate i ngā pito e rua mā te dienone, mā te tauhohenga whakawhiti ester rānei o te ethyl acetoacetate me te polyol polyether, kātahi ka whakananua te polyether kua taupokina e te rōpū acetoacetate ki te amine mono-primary, te amine alcohol alkyl, te amine tuatahi dibasic rānei hei whiwhi i tētahi matū imine he iti te matotoru me te rōpū mutunga aminobutyrate.
