1. Cov khoom ntawm DMEA:
Cov Khoom Siv Lub Cev: Dmea yog cov kua tsis muaj xim uas muaj cov khoom siv ntom ntawm lub cev xws li ntawj, melting point, boiling taw tes thiab rwg taw tes ntsuas. Nws yog yooj yim soluble hauv dej thiab tseem tuaj yeem ua kom tiav nrog ntau yam ntawm cov kuab tshuaj organic xws li etherone thiab ntxhiab hydrocarbons.
Tshuaj lom neeg cov khoom: D MOLECEY muaj cov pab pawg hydroxyl thiab pab pawg amino, yog li nws muaj cov tshuaj lom neeg ntawm cov cawv thiab cov amines. Nws tuaj yeem ua rau muaj cov kua qaub los ua cov ntsev, thiab tseem tuaj yeem hnov cov ntsev, thiab cov khoom siv ketones thiab ketones los tsim cov hauv paus scec. Ib qho ntxiv, DM.a tseem tuaj yeem yauv ntau yam ntawm synthes synthesis cov tshuaj tiv thaiv, xws li alkylation, acylation, etcation, thiab lwm yam.
2. Daim ntawv thov ntawm DMEA
Resin Raw cov khoom siv: DMEA tuaj yeem siv ua cov khoom siv cob cov khoom lag luam thiab koom nrog hauv synthesis thiab kev ua ntawm resins.
Cov khoom siv raw rau tshuaj, dyes thiab pleev xim cov kuab tshuaj: thiab yog siv los ua ke ntau yam kev siv hluav taws xob, dyes thiab xim av.
Kev Npaj Xim: DMEA tuaj yeem siv los npaj cov xim tsev-dilutable los txhim kho kev ua tau zoo thiab cov xim pleev xim zoo.
Polyurethane ua npuas ncauj categalst: Hauv kev tsim cov polyurethane ua npuas ncauj, DMEA tuaj yeem siv ua cov synthesis thiab ua npuas dej ntawm polyurethane. Nws tau muaj kev ua si tsawg catalytic, tab sis muaj cov nyhuv me me ntawm cov tshuaj tiv thaiv me me thiab muaj peev xwm tswj cov khoom siv ua kom ruaj khov, yog li tswj hwm qhov ruaj khov ntawm lwm cov amines hauv lub system. DMEA yog tus nqi pheej yig thiab yog qhov tshwj xeeb tshaj plaws thaum siv hauv kev sib xyaw nrog Trietylenediamine, uas tuaj yeem txo cov nqi ntau lawm.
Lwm yam kev siv: DMEA kuj tseem siv tau los txhawb cov neeg sawv cev (cov tshuaj ntsuab, thiab lwm yam siv tau ua tus neeg saib xyuas dej kom tiv thaiv kev mob rwj.
