Kaihanga Utu Pai D2000 CAS: 9046-10-0

whakaahuatanga poto:

Ko te Amine-TerminatedPolyether (D2000) he karaehe o nga puhui polyolefin me te tuara polyether ngawari, ka kapi e nga roopu amine tuatahi, tuarua ranei.Na te mea ko te mekameka matua o te ngota ngota he mekameka polyether ngawari, a ko te hauwai i runga i te kapeka o te polyether amine he kaha ake i te hauwai i runga i te roopu hydroxyl kapeka o te polyether, na reira, ka taea e te polyether amine te whakakapi pai mo te polyether i etahi rauemi nga tukanga, a ka taea te whakapai ake i te mahinga tono o nga rauemi hou.D2000 e whakamahia nuitia ana i roto i te polyurethane tauhohe i werohia rauemi niao, polyurea rehu, epoxy kapia whakaora āpiha me te penehīni hamuhamu.

Nga Ahuatanga Matū: Ko te poly(propylene glycol) bis(2-aminopropyl ether) he wai marama kowhai, he tae kore ranei i te pāmahana o te rūma, me nga painga o te iti o te pokey, te iti o te pehanga kohu me te nui o nga ihirangi amine tuatahi, a ka whakarewahia i roto i nga whakarewa penei i te waiwaro, waiwaro aliphatic, waiwaro kakara, esters, glycol ethers, ketones me te wai.

Nga tono mo D2000

Ko te poly(propylene glycol) bis(2-aminopropyl ether) he pai te parenga kawakore me te wai me te aukati waikawa ngawari.Ko nga kapia epoxy kua rongoa ki te polyetheramines he pai nga ahuatanga hiko.He mea ahurei nga polyetheramines, ka whakamahia i roto i te tata katoa o nga tono epoxy penei i te paninga, i nga rawa kohua, i nga rawa hanga, i nga hiato me nga taapiri.
Te Whakaritenga:Te whakahiato o te Poly(propylene glycol) bis(2-aminopropyl ether): Tuatahi, ka piri te polyether ki te roopu acetoacetate i nga pito e rua ma te dienone, ma te tauhohenga whakawhiti ester ranei o te ethyl acetoacetate me te polyether polyol, katahi ka kapi te polyether. na te roopu acetoacetate ka whakaminea ki te amine mono-tuatahi, amine waipiro alkyl, amine tuatahi dibasic ranei ki te whiwhi i te pūhui imine me te iti o te pokey me te roopu mutunga aminobutyrate.
