2-hydroxyethyl methacrylate(HEMA) ndeye organic polymerization monomer inoumbwa nekuita kwe ethylene oxide (EO) uye methacrylic acid (MMA), iyo ine bifunctional mapoka mukati memorekuru. Hydroxyethyl methacrylate imhando yemvura isina ruvara, yakajeka, uye inoyerera zviri nyore. Soluble mune zvakajairika organic solvents. Kusanganiswa nemvura.

Kushandiswa kweHEMA
1. Inonyanya kushandiswa pakugadzirisa resins uye machira. Copolymerization nemamwe ma acrylic monomers anogona kugadzira acrylic resins ane anoshanda hydroxyl mapoka mumaketani epadivi, ayo anogona kupinda esterification uye crosslinking maitiro, synthesize insoluble resins, inovandudza adhesion, uye inogona kushandiswa sefiber kurapwa vamiririri. Inopindirana ne melamine formaldehyde (kana urea formaldehyde) resin, epoxy resin, nezvimwewo kugadzira maviri-component coatings. Kuiwedzera kupendi yemotokari yepamusoro kunogona kuchengetedza girazi rayo kwenguva yakareba. Inogona zvakare kushandiswa seanonamira kune ekugadzira machira uye yekurapa polymer monomers.
2. HEMA inoshandiswa kugadzira resins yekupfeka, majasi emota uye maprimers, pamwe nephotopolymer resins, mabhodhi ekudhinda, ingi, gel (contact lenses) uye tinning zvinhu zvekupfeka, transmission electron microscopy (TEM) uye optical microscopy (LM) embedding. reagents, kunyanya kune hydration samples dze "sensitive antigen sites". Mvura chena senge, inonamira, yakatetepa kupfuura mvura, uye iri nyore kupinda kupfuura chero resin kana monomer. Inonyanya kushandiswa kushanda pamapfupa, cartilage, uye yakaoma kupinda mumiti yezvirimwa.
3. Indasitiri yepurasitiki inoshandiswa kugadzira acrylic resins ine inoshanda hydroxyl mapoka. Indasitiri yekuputira inoshandiswa pamwe chete ne epoxy resins, diisocyanates, melamine formaldehyde resins, nezvimwewo kugadzira maviri-component coatings. Indasitiri yeoiri inoshandiswa sechinhu chinowedzera pakuzora mafuta kugeza. Indasitiri yemagetsi inoshandiswa sechinhu chinopedza mvura mumuviri kune ma electron microscopes. Zvinamira zvinoshandiswa muindasitiri yemachira kugadzira machira. Inoshandiswa semakemikari reagent mu analytical chemistry. Pamusoro pezvo, inoshandiswawo sechinhu chinonyungudika nemvura inonyungudika yekugadzira zvinhu zvekurapa zvepolymer, thermosetting coatings, uye zvinonamira.
Ramangwana reHEMA:
Vanoongorora maindasitiri vataura kuti nekuda kwekuita kwayo kwakaringana, hydroxyethyl methacrylate parizvino ine kudiwa kwakanyanya kwemanyorerwo, kunyanya muminda yekurapa uye yepamusoro-yekupedzisira machira, ine tarisiro inovimbisa. Pachine mikana yebudiriro mumusika unotevera wehydroxyethyl methacrylate. Padivi rekuda: Nekukurumidza kukura kwekudiwa muminda yakaita semajasi nemanamira, kushandiswa kwe2-hydroxyethyl methacrylate kuri kuramba kuchiwedzera. Nehunyanzvi,HEMAtekinoroji yekugadzira uye tekinoroji yekugadzira polyether inogona kudzidza kubva kune imwe neimwe maererano nedhizaini, zvishandiso, maitiro, uye mashandiro.Maererano neketani yemaindasitiri: kugadzirwa kwepamusoro-kuguma hydroxyethyl methacrylate zvigadzirwa zvinogona kubatanidza kumusoro methacrylic acid uye ethylene oxide zvishandiso, pamwe chete nekudzika kwemvura-based coating devices. Panguva imwecheteyo, hydroxyethyl methacrylate chinhu chakakosha pamusika webhizimusi repamusoro, kuve nechokwadi chekupihwa kweakakosha mamonomers ebhizinesi rezasi, kuwedzera maindasitiri ketani, uye kuwedzera kuwedzera kukosha kwechigadzirwa. . Kuti ibatanidze chikamu chayo chemusika, kambani yakafunga kuwedzera kwayo yepakutanga kugadzirwa kwemidziyo uye nekuwedzera kuchenesa iyo yekutanga nzira yekurasa mvura kuti iwedzere yayo yekugadzira kugona.
