HEMA CAS 868-77-9 2-Hydroxyethyl methacrylate
2-Hydroxyethyl methacrylate / HEMA waa walxo kiimiko ah oo dabiici ah, wax lagu daro, walxo kiimiko cayriin, walxo kiimikaad maalinle ah.Waxaa inta badan loo isticmaalaa wax ka beddelka resins iyo dahaarka.Copolymerization la monomers kale acrylic waxay soo saari kartaa resin acrylic leh kooxaha hydroxyl firfircoon ee silsiladda dhinaca, kaas oo loo isticmaali karo esterification iyo falcelinta isku-tallaabta ah, synthesize of resin aan la milmin iyo hagaajinta adhesion, oo loo isticmaali karaa sida wakiilka daaweynta fiber.Waxay la falgashaa melamine formaldehyde (ama urea formaldehyde) xabagta, resin epoxy, iwm. si ay u soo saarto daahan laba qaybood ka kooban.
