2-hydroxyethyl methacrylate(HEMA) waa monomer polymerization organic oo ay samaysay falcelinta ethylene oxide (EO) iyo methacrylic acid (MMA), kaas oo ka kooban kooxo laba-shaqo leh oo ku dhex jira molecule. Hydroxyethyl methacrylate waa nooc ka mid ah dareere aan midab lahayn, hufan, oo si fudud u socda. Ku milma dareerayaasha dabiiciga ah ee caadiga ah. Ku qallafsanaan biyo.

Codsiga HEMA
1. Inta badan loo isticmaalo wax ka beddelka resins iyo dahaarka. Copolymerization-ka monomers kale ee acrylic waxay soo saari kartaa resins acrylic oo leh kooxo hydroxyl firfircoon ee silsiladaha dhinaca, kuwaas oo mari kara falcelinta esterification iyo isku-dhafka, isku-darka resins-ka, hagaajinta adhesion, waxaana loo isticmaali karaa sida wakiilada daaweynta fiber. Waxay la falgashaa melamine formaldehyde (ama urea formaldehyde) xabagta, resin epoxy, iwm si ay u soo saarto daahan laba qaybood ka kooban. Ku darida rinjiga sare ee baabuurta waxay ilaalin kartaa dhalaalka muraayadda wakhti dheer. Waxa kale oo loo isticmaali karaa sidii koollo ahaan dunta synthetic iyo monomers-ka polymer-ka ee caafimaadka.
2. HEMA waxaa loo isticmaalaa in lagu soo saaro resins for daahan, topcoats baabuurta iyo primers, iyo sidoo kale resins photopolymer, looxa daabacaadda, khadadka, jel (lenses xiriir) iyo daahan walxaha qasacadaysan, gudbinta elektarooniga microscopy (TEM) iyo mikroskoob indhaha (LM). reagents, gaar ahaan shaybaarada fuuq-celinta ee "goobaha antigen-ka xasaasiga ah". Biyaha cad waxay jecel yihiin, dhegdheg yihiin, ka khafiifsan yihiin biyaha, wayna ka sahlan tahay in la dhex geliyo si ka yar resin ama monomer kasta. Si gaar ah loogu isticmaalo shaqada lafaha, carjawda, iyo ay adagtahay in la dhex geliyo unugyada dhirta.
3. Warshadaha caagga ah waxaa loo isticmaalaa in lagu soo saaro resins acrylic oo ay ku jiraan kooxaha hydroxyl firfircoon. Warshadaha dahaarka waxaa loo isticmaalaa iyada oo lala kaashanayo resins epoxy, diisocyanates, resins formaldehyde melamine, iwm si loo soo saaro daahan laba qaybood ah. Warshadaha saliidda waxa loo isticmaalaa wax lagu daro si saliida lagu dhaqo. Warshadaha elektaroonigga ah waxaa loo isticmaalaa sidii wakiilka fuuq-baxa ee mikroskoobyada elektarooniga ah. Xabagyada loo isticmaalo warshadaha dharka si loo soo saaro dhar. Loo isticmaalo sidii reagen kiimiko ahaan kiimikaad falanqaynta. Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa sida wakiilka gundhig biyo-milmi leh oo loogu talagalay soo saarista walxaha polymer-ka caafimaadka, dahaarka heerkulbeegga, iyo koollada.
MustaqbalkaHEMA:
Falanqeeyayaasha warshadaha ayaa sheegay in iyada oo ay ugu wacan tahay waxqabadkeeda dhammaystiran ee heer sare ah, hydroxyethyl methacrylate hadda waxay leedahay baahi sare oo codsiyada, gaar ahaan dhinacyada caafimaadka iyo dahaarka sare, oo leh rajooyin rajo leh. Waxaa weli jira fursado horumarineed ee suuqa mustaqbalka ee hydroxyethyl methacrylate. Dhanka baahida: Iyada oo kobaca degdega ah ee baahida beeraha sida dahaarka iyo xabagta, isticmaalka 2-hydroxyethyl methacrylate ayaa si joogto ah u kordhaya. Farsamo ahaan,HEMATignoolajiyada wax-soo-saarka iyo tignoolajiyada wax-soo-saarka polyeter-ka waxay wax ka baran karaan midba midka kale marka loo eego naqshadeynta, qalabka, habka, iyo hawlgalka.Marka la eego silsiladda warshadaha: horumarinta alaabada methacrylate hydroxyethyl-dhamaadka sare waxay isku xiri kartaa aaladaha methacrylic acid iyo ethylene oxide, iyo sidoo kale qalabka daahan biyaha ku salaysan hoose. Isla mar ahaantaana, hydroxyethyl methacrylate waa alaab muhiim ah oo ceeriin ah oo loogu talagalay ganacsiga alaabta dusha sare, hubinta bixinta monomers muhiimka ah ee ganacsiga hoose, ballaarinta silsiladda warshadaha, iyo kordhinta qiimaha alaabta. . Si loo xoojiyo saamigeeda suuqa, shirkaddu waxay go'aansatay inay kordhiso awoodda wax-soo-saarka qalabka asalka ah oo ay sii nadiifiso habka asalka ah ee qashinka qashinka si ay u kordhiso awoodeeda wax-soo-saarka.
