2-Hydroxyethyl Methacrylate HEMA CAS 868-77-9 daahirnimo>99.0% (GC)

2-Hydroxyethyl Methacrylate (HEMA) (ku xasilay MEHQ) (CAS: 868-77-9) waxay ahayd monomer-kii ugu horreeyay ee loo isticmaalo in lagu farsameeyo hydrogels ee codsiyada cilmiga noolaha.Sifooyinka bararka biyaha ee HEMA waxa lagu xoojiyey kobolymerization-ka oo leh monomers badan oo biyo-biyood ah.HEMA waxay heshaa codsiyo ballaarankeenista daroogada.HEMA waxa loo isticmaalaa isku-xidhka koblymersyada bayoloji ahaan shaqaynaysa (2-hydroxyethyl methacrylate) (PHEMA).Waxa kale oo loo isticmaalaa in lagu diyaariyo xuubka ka jawaabaya iftiinka ee PHEMA,HEMA/ acrylamide ku salaysan dawada gaarka ah ee sii daynta hydrogel, iyo HEMA/methacrylic acid hydrogel ee biyaha ku milma si daroogada loo gaadhsiiyo.Saamaynta HEMA ee guuritaanka unugyada tarma ee saxarka ilkaha (in vitro) ayaa laga yaabaa in la darso.Waxaa inta badan loo isticmaalaa resin iyo wax ka beddelka dahaarka.Loo isticmaalo soo saarista rinjiga, rinjiga baabuurka iyo alwaaxyada leh xabagta, resin polymer waxaa lagu dabaqi karaa iftiinka, looxa ciyaarta, khad daabacaadda, jel (lenses) iyo dahaarka walxaha qasacadaysan, mikroskoob elektaroonig ah (TEM) iyo mikroskoob indhaha (LM) ) isku dhejinta reagent, muunado loo isticmaalo "goobaha antigen-ka xasaasiga ah" ee fuuq-baxa.Warshadaha caaga ah ee loo isticmaalo soo saarista ay ku jiraan resin hydroxyl acrylic firfircoon.HEMA waxaa si weyn loogu dabaqaa soo saarista xabagta acrylic hydroxyl oo leh koox firfircoon iyo dejinta warshadaha daahan iyo resin epoxy, diisocyanate iyo melamino-formaldehyde resin ee soo saarista laba qaybood oo ka mid ah daahan iyo shaqada dhaqida lagu daro saliidda saliidda ee warshadaha wax soo saarka saliidda.Codsiga faahfaahsan: HEMA waxaa inta badan loo isticmaalaa daawaynta kulaylka resin daahan acrylic, nalka daawaynta acrylic daahan, resin photosensitive, resin daahan biyo-milmi leh, koollada, wakiilka daaweynta dharka, ester processing iyo polymer modifier, polycarboxylic acid yaraynta wakiilka Marka la eego Wakiilka biyaha, iwm, waxay leedahay sifooyinka qiyaasta qiyaasta yar, laakiin waxay si weyn u hagaajin kartaa waxqabadka alaabta.Comonomer ee emulsion polymerization, dhumuc iyo kala firdhiya iyo joojinta gargaarka.
