Umkhiqizi Intengo Enhle D2000 CAS: 9046-10-0

incazelo emfushane:

I-Amine-TerminatedPolyether (D2000) iyikilasi lezinhlanganisela ze-polyolefin ezinomgogodla othambile we-polyether, oboshwe ngamaqembu ayisisekelo noma wesibili we-amine. Ngenxa yokuthi iketango eliyinhloko le-molecule iyiketango elithambile le-polyether, futhi i-hydrogen esesiphelweni se-polyether amine isebenza kakhulu kune-hydrogen eseqenjini le-hydroxyl le-polyether, ngakho-ke, i-polyether amine ingaba indawo enhle ye-polyether kwezinye izinqubo zezinto ezibonakalayo, futhi ingathuthukisa ukusebenza kwesicelo sezinto ezintsha. I-D2000 isetshenziswa kakhulu ezintweni zokubumba umjovo we-polyurethane osebenzayo, ukufafaza kwe-polyurea, ama-epoxy resin zokwelapha ama-ejenti kanye nama-scavengers kaphethiloli.

Izici Zekhemikhali:I-Poly(propylene glycol) bis(2-aminopropyl ether) iwuketshezi olukhanyayo oluphuzi noma olungenambala olubonisa ngale ekamelweni lokushisa, olunobuhle be-viscosity ephansi, umfutho ophansi womhwamuko nokuqukethwe okuphezulu kwe-amine, futhi inyibilika kuzincibilikisi ezifana ne-ethanol, ama-aliphatic hydrocarbons, i-aromatic water s, i-hydroglycolsther, i-esters yamanzi.

Izicelo ze-D2000

I-Poly(propylene glycol) bis(2-aminopropyl ether) inokumelana okuhle kwe-alkali namanzi nokumelana ne-asidi okumaphakathi. Ama-epoxy resins alashwe nge-polyetheramines anezakhiwo ezinhle zikagesi. Ama-polyetheramines anezakhiwo eziyingqayizivele futhi asetshenziswa cishe kuzo zonke izinhlelo zokusebenza ze-epoxy ezifana nezingubo, izinto zokubumba, izinto zokwakha, izinhlanganisela nezinamathiselo.
Ukulungiselela:ukwenziwa kwe-Poly(propylene glycol) bis(2-aminopropyl ether): Okokuqala, i-polyether ixhunywe eqenjini le-acetoacetate kuzo zombili iziphetho nge-dienone noma ngokusabela kokushintshisana kwe-ester kwe-ethyl acetoacetate nge-polyether polyol, bese i-polyether embozwe i-acetoacetate ye-acetoacetate ne-alcohol iqoqo le-acetoacetate noma i-alcohol i-acetoacetate i-dibasic primary amine ukuthola inhlanganisela ye-imine ene-viscosity ephansi eneqembu lokugcina le-aminobutyrate.
