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 he mekameka polyether ngohengohe, 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 kāpeka o te polyether, na reira, ka taea e te polyether amine te whakakapi pai mo te polyether i roto i etahi tukanga rauemi, a ka taea te whakapai ake i te mahi 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 scavengers.

Nga Ahuatanga Matū: Ko te poly(propylene glycol) bis(2-aminopropyl ether) he wai marama kowhai, he tae kore ranei i te pāmahana rūma, me te painga o te iti o te pokey, te iti o te pehanga kohu me te nui o te waikawa amine tuatahi, ka whakarewahia i roto i nga whakarewa penei i te waiwaro, aliphatic hydrocarbons, hydrocarbons 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 ki nga tono epoxy katoa penei i te whakakikorua, i nga rauemi kohua, i nga rawa hanga, i nga hiato me nga whakapiri.
Whakaritenga: te whakahiatotanga o te Poly(propylene glycol) bis(2-aminopropyl ether): Tuatahi, ka piri te polyether ki te roopu acetoacetate i nga pito e rua na te dienone, na roto ranei i te tauhohenga whakawhiti ester o te ethyl acetoacetate me te polyether polyol, katahi ko te polyether e kapi ana e te roopu acetoacetate-a-amine-amine-amine-a-muamua ka whakakohia ki te waipiro acetoacetate monoprimary ranei. amine ki te whiwhi i te pūhui imine me te pokey iti me te roopu mutunga aminobutyrate.
