Txheej txheem cej luam ntawm Epoxy Resin

Epoxy resin yog lub siab molecular polymer nrog cov qauv molecular (C11H12O3)n, uas yog hais txog lub ntsiab lus dav dav rau cov chav kawm ntawm cov polymers uas muaj ntau tshaj ob pawg epoxy hauv cov molecule. Nws yog polycondensation khoom ntawm epichlorohydrin thiab bisphenol A los yog polyol. Vim yog cov tshuaj lom neeg ua haujlwm ntawm epoxy pab pawg, ntau yam sib txuas uas muaj cov khoom siv hydrogen tuaj yeem siv los qhib lub nplhaib, kho thiab crosslink los tsim ib lub network qauv, yog li nws yog thermosetting resin. Bisphenol A epoxy resin tsis yog tsuas yog qhov loj tshaj plaws nyob rau hauv cov zis thiab ua tiav ntau yam, tab sis kuj tseem hloov tshiab ntau yam tseem nce ntxiv, thiab qhov zoo yog pheej txhim kho.
