I-2-hydroxyethyl methacrylate(HEMA) yi-organic polymerization monomer eyenziwe yi-reaction ye-ethylene oxide (EO) kunye ne-methacrylic acid (MMA), equlethe amaqela asebenzayo ngaphakathi kwe-molecule. IHydroxyethyl methacrylate luhlobo lolwelo olungenambala, olungafihliyo, noluqukuqela ngokulula. Inyibilika kwizinyibilikisi eziqhelekileyo eziphilayo. Ixutywe namanzi.

Ukusetyenziswa kwe-HEMA
1. Ikakhulu isetyenziselwa ukuguqula i-resin kunye neengubo. I-Copolymerization kunye nezinye ii-monomers ze-acrylic zinokuvelisa ii-resin ze-acrylic kunye namaqela asebenzayo e-hydroxyl kumatyathanga asecaleni, anokungena kwi-esterification kunye ne-crosslinking reactions, i-synthesize i-resins enganyibilikiyo, iphucule ukunamathela, kwaye inokusetyenziswa njengeejenti zonyango lwefayibha. Isabela kunye ne-melamine formaldehyde (okanye i-urea formaldehyde) i-resin, i-epoxy resin, njl.njl. ukwenza iingubo ezimbini zokugquma. Ukuyongeza kwipeyinti yemoto ephezulu kunokugcina iglosi yesipili sayo ixesha elide. Isenokusetyenziswa njengento encamathelayo kwizinto ezilukiweyo ezenziweyo kunye neemonomers zepolymer zonyango.
2. I-HEMA isetyenziselwa ukuvelisa i-resins yokugqoka, i-topcoats ye-automotive kunye ne-primers, kunye ne-photopolymer resins, iibhodi zokuprinta, ii-inki, i-gel (i-contact lens) kunye ne-tinning material coatings, ukuhanjiswa kwe-electron microscopy (TEM) kunye ne-optical microscopy (LM) embedding. ii-reagents, ngakumbi kwiisampuli ze-hydration "zeendawo ze-antigen ezinobuthathaka". Amanzi amhlophe anje, ancangathi, mancinci kunamanzi, kwaye kulula ukungena kunayo nayiphi na intlaka okanye imonoma. Ngokukhethekileyo isetyenziselwa umsebenzi kumathambo, i-cartilage, kwaye kunzima ukungena kwiithishu zezityalo.
3. Ishishini leplastiki lisetyenziselwa ukwenza iireyini ze-acrylic eziqukethe amaqela asebenzayo e-hydroxyl. Ishishini le-coating lisetyenziswe ngokubambisana ne-epoxy resins, i-disocyanates, i-melamine formaldehyde resins, njl. Ishishini leoli lisetyenziswa njengesongezo sokuthambisa ioyile yokuhlamba. Ishishini le-elektroniki lisetyenziswa njenge-arhente yokuphelisa amanzi kwi-electron microscopes. Izinto zokuncamathelisa ezisetyenziswa kushishino lwempahla olulukiweyo ukwenza amalaphu. Isetyenziswe njenge-reagent yekhemikhali kwi-analytical chemistry. Ukongeza, ikwasetyenziswa njengearhente yokufakela enyibilikayo emanzini ukwenza izinto zepolymer zonyango, i-thermosetting coatings, kunye nezinto ezincamathelayo.
Ikamva leI-HEMA:
Abahlalutyi bemizi-mveliso bathi ngenxa yokusebenza kwayo okugqwesileyo, i-hydroxyethyl methacrylate okwangoku inemfuno ephezulu yezicelo, ngakumbi kwiinkalo zonyango kunye nomgangatho ophezulu wokugquma, ngamathemba athembisayo. Kusekho amathuba ophuhliso kwimarike yexesha elizayo ye-hydroxyethyl methacrylate. Kwicala lemfuno: Ngokukhula okukhawulezayo kwemfuno kwiinkalo ezifana neengubo kunye ne-adhesives, ukusetyenziswa kwe-2-hydroxyethyl methacrylate kukhula ngokuthe ngcembe. Ngokobuchwephesha,I-HEMAitekhnoloji yokuvelisa kunye neteknoloji yokuvelisa i-polyether inokufunda omnye komnye malunga noyilo, izixhobo, inkqubo, kunye nokusebenza.Ngokubhekiselele kwikhonkco lezoshishino: uphuhliso lwemveliso ephezulu ye-hydroxyethyl methacrylate inokudibanisa phezulu kwi-methacrylic acid kunye nezixhobo ze-ethylene oxide, kunye nezixhobo zokugquma ezisekelwe emanzini ezisezantsi. Kwangaxeshanye, i-hydroxyethyl methacrylate yinto ebalulekileyo kwishishini lezinto ezibonakalayo, eqinisekisa ukunikezelwa kweemonomers eziphambili kushishino olusezantsi, ukwandisa ikhonkco lezoshishino, kunye nokwandisa ixabiso lemveliso. . Ukuze uhlanganise isabelo sayo semarike, inkampani iye yagqiba ekubeni yonyuse umthamo wemveliso yesixhobo sokuqala kwaye ihlambulule ngakumbi inkqubo yoqobo yenkunkuma yolwelo ukwandisa umthamo wayo wemveliso.
