Mugadziri Mutengo Wakanaka D2000 CAS: 9046-10-0

tsananguro pfupi:

Amine-TerminatedPolyether (D2000) ikirasi yemakomponi epololefin ane musana wakapfava wepolyether, wakavharirwa nemapoka ekutanga kana echipiri emamine.Nekuti cheni huru yemorekuru iketani yepolyether yakapfava, uye iyo hydrogen pamugumo wepolyether amine inoshanda zvakanyanya kupfuura iyo hydrogen pane terminal hydroxyl boka repolyether, saka, polyether amine inogona kutsiva yakanaka yepolyether mune zvimwe zvinhu. maitiro, uye anogona kuvandudza mashandiro ekushandisa kwezvinhu zvitsva.D2000 inoshandiswa zvakanyanya mu polyurethane reactive jekiseni rekuumba zvinhu, polyurea spraying, epoxy resin kuporesa vamiririri uye peturu scavengers.

Chemical Properties:Poly(propylene glycol) bis(2-aminopropyl ether) imvura yakareruka yero kana isina ruvara inoonekera patembiricha yekamuri, ine zvakanakira zve low viscosity, low vapor pressure uye high primary amine content, uye inonyungudika musolvents senge. ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones nemvura.

Zvikumbiro zveD2000

Poly(propylene glycol) bis(2-aminopropyl ether) ine alkali yakanaka uye inodzivirira mvura uye ine mwero acid kuramba.Epoxy resins inorapwa ne polyetheramines ine yakanaka magetsi emagetsi.Polyetheramines ane zvimiro zvakasiyana uye anoshandiswa mune angangoita ese epoxy application senge machira, mapoto, zvekuvakisa, macomposites uye zvinonamira.
Kugadzirira: synthesis yePoly (propylene glycol) bis (2-aminopropyl ether): Chekutanga, iyo polyether inosungirirwa kuboka reacetoacetate kumativi ose nedienone kana kuburikidza ne ester exchange reaction ye ethyl acetoacetate ne polyether polyol, uye polyether yakavharwa. neboka reacetoacetate rinosvibiswa ne mono-primary amine, alkyl alcohol amine kana dibasic primary amine kuwana musanganiswa weimine neine viscosity yakaderera neboka rekupedzisira reaminobutyrate.
