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 e-hydroxyl asebenzayo. 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.
