Chaw tsim tshuaj paus Zoo Nqe D2000 CAS: 9046-10-0

piav qhia luv luv:

Amine-TerminatedPolyether (D2000) yog ib chav kawm ntawm polyolefin tebchaw nrog cov pob txha mos polyether, capped los ntawm thawj lossis theem nrab amine pawg.Vim hais tias cov saw tseem ceeb ntawm cov molecule yog ib qho muag muag polyether saw, thiab cov hydrogen ntawm lub davhlau ya nyob twg ntawm polyether amine yog active dua li cov hydrogen ntawm lub davhlau ya nyob twg hydroxyl pawg ntawm polyether, yog li ntawd, polyether amine tuaj yeem hloov tau zoo rau polyether hauv qee yam khoom siv. cov txheej txheem, thiab tuaj yeem txhim kho daim ntawv thov kev ua haujlwm ntawm cov ntaub ntawv tshiab.D2000 yog siv dav hauv polyurethane reactive txhaj tshuaj molding cov ntaub ntawv, polyurea txau, epoxy resin curing agents thiab roj av scavengers.

Chemical Properties: Poly (propylene glycol) bis (2-aminopropyl ether) yog lub teeb daj lossis xim tsis muaj xim pob tshab ntawm chav sov, nrog qhov zoo ntawm cov viscosity tsawg, tsis tshua muaj vapor siab thiab siab cov ntsiab lus amine, thiab yog soluble hauv cov kuab tshuaj xws li ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones thiab dej.

Kev siv ntawm D2000

Poly (propylene glycol) bis (2-aminopropyl ether) muaj alkali zoo thiab dej tsis kam thiab acid acid tsis kam.Epoxy resins kho nrog polyetheramines muaj cov khoom hluav taws xob zoo.Polyetheramines muaj cov khoom tshwj xeeb thiab yog siv rau hauv yuav luag txhua daim ntawv thov epoxy xws li txheej txheej, cov khoom siv potting, cov khoom siv, cov khoom sib xyaw thiab cov nplaum.
Kev npaj: synthesis ntawm Poly (propylene glycol) bis (2-aminopropyl ether): Ua ntej, cov polyether txuas nrog acetoacetate pawg ntawm ob qho kawg los ntawm dienone los yog los ntawm ester pauv cov tshuaj tiv thaiv ntawm ethyl acetoacetate nrog polyether polyol, thiab tom qab ntawd cov polyether capped los ntawm pawg acetoacetate yog aminated nrog mono-primary amine, alkyl cawv amine los yog dibasic thawj amine kom tau txais ib qho imine compound nrog cov viscosity tsawg nrog ib pawg aminobutyrate kawg.
