I-2-hydroxyethyl methacrylate(HEMA) i-organic polymerization monomer eyakhiwe ukusabela kwe-ethylene oxide (EO) ne-methacrylic acid (MMA), equkethe amaqembu asebenza kabili ngaphakathi kwe-molecule.IHydroxyethyl methacrylate iwuhlobo loketshezi olungenambala, olusobala, futhi olugeleza kalula.Incibilika kuma-solvents ajwayelekile.Hlanganisa namanzi.

Ukusetshenziswa kwe-HEMA
1. Ikakhulukazi esetshenziselwa ukulungisa ama-resin kanye nama-coatings.I-Copolymerization namanye ama-monomers e-acrylic angakhiqiza ama-acrylic resins anamaqembu e-hydroxyl asebenzayo emaketangeni aseceleni, angabhekana nokusabela kwe-esterification nokuphambana, ahlanganise ama-resin angancibiliki, athuthukise ukunamathela, futhi angasetshenziswa njengama-ejenti okwelapha i-fiber.Ihlangana ne-melamine formaldehyde (noma i-urea formaldehyde) inhlaka, i-epoxy resin, njll. ukuze yenze izimbotshana ezinezingxenye ezimbili.Ukuyengeza kupende wemoto osezingeni eliphezulu kungagcina isicwebezelisi sesibuko sayo isikhathi eside.Ingasetshenziswa futhi njenge-adhesive yezindwangu zokwenziwa kanye ne-polymer monomers yezokwelapha.
2. I-HEMA isetshenziselwa ukukhiqiza izinsalela zokumboza, amajazi angaphezulu ezimoto kanye nama-primer, kanye nezinhlaka ze-photopolymer, amabhodi okuphrinta, oyinki, ijeli (amalensi othintana naye) nezinto zokumboza ze-tinning, i-transmission electron microscopy (TEM) kanye ne-optical microscopy (LM) yokushumeka. ama-reagents, ikakhulukazi amasampula e-hydration "amasayithi e-antigen azwelayo".Amanzi amhlophe afana, anamathelayo, azacile kunamanzi, futhi kulula ukungena kunanoma iyiphi inhlaka noma i-monomer.Isetshenziselwa ngokukhethekile umsebenzi wamathambo, uqwanga, futhi kunzima ukungena ezicutshini zezitshalo.
3. Imboni yepulasitiki isetshenziselwa ukwenza ama-acrylic resins aqukethe amaqembu asebenzayo e-hydroxyl.Imboni yokugqoka isetshenziswa ngokuhambisana nama-epoxy resins, ama-disocyanates, ama-melamine formaldehyde resins, njll.Imboni kawoyela isetshenziswa njengesengezo sokuthambisa uwoyela ukuwasha.Imboni ye-elekthronikhi isetshenziswa njenge-ejenti eqeda amanzi emzimbeni wama-electron microscopes.Izinamatheliso ezisetshenziswa embonini yendwangu ukwenza izindwangu.Isetshenziswa njenge-reagent yamakhemikhali kukhemikhali yokuhlaziya.Ngaphezu kwalokho, iphinde isetshenziswe njenge-ejenti yokushumeka encibilika emanzini ukuze kuhlanganiswe izinto ze-polymer yezokwelapha, i-thermosetting coatings, nezinamatheliso.
Ikusasa leI-HEMA:
Abahlaziyi bezimboni baveze ukuthi ngenxa yokusebenza kwayo okuhle kakhulu okuphelele, i-hydroxyethyl methacrylate njengamanje inesidingo esikhulu sokufakwa kwezicelo, ikakhulukazi emikhakheni yezingubo zezokwelapha nezisezingeni eliphezulu, ngamathemba athembisayo.Asekhona amathuba entuthuko emakethe yesikhathi esizayo ye-hydroxyethyl methacrylate. Ngasohlangothini lwesidingo: Ngokukhula okusheshayo kwesidingo emikhakheni efana nezingubo zokunamathela nezinamatheliso, ukusetshenziswa kwe-2-hydroxyethyl methacrylate kukhula kancane kancane. Ngokobuchwepheshe,I-HEMAubuchwepheshe bokukhiqiza kanye nobuchwepheshe bokukhiqiza i-polyether bungafunda komunye nomunye mayelana nokuklama, okokusebenza, inqubo, nokusebenza.Ngokochungechunge lwezimboni: ukuthuthukiswa kwemikhiqizo ephezulu ye-hydroxyethyl methacrylate ingaxhumanisa phezulu nomfula i-methacrylic acid kanye nemishini ye-ethylene oxide, kanye nezinto zokumboza ezansi nomfula ezisekelwe emanzini.Ngaso leso sikhathi, i-hydroxyethyl methacrylate iyimpahla ebalulekile ebalulekile yebhizinisi lezinto ezibonakalayo, eqinisekisa ukuhlinzekwa kwama-monomers abalulekile ebhizinisi elingezansi, ukwandisa uchungechunge lwezimboni, nokwandisa inani lomkhiqizo. .Ukuze kuqiniswe isabelo sayo semakethe, inkampani inqume ukukhulisa amandla ayo okukhiqiza imishini futhi iqhubeke nokuhlanza uketshezi lwakuqala lukadoti ukuze yandise umthamo wayo wokukhiqiza.
