Tšebeliso ea HEMA
1. Haholo-holo e sebelisetsoa ho fetola li-resin le liphahlo. Copolymerization e nang le li-monomers tse ling tsa acrylic e ka hlahisa li-resin tsa acrylic tse nang le lihlopha tse sebetsang tsa hydroxyl ka har'a liketane tse ka mahlakoreng, tse ka kenang karabelo ea esterification le crosslinking, synthesize li-resin tse sa qhibiliheng, tsa ntlafatsa ho khomarela, 'me li ka sebelisoa e le lisebelisoa tsa kalafo ea fiber. E sebetsana le melamine formaldehyde (kapa urea formaldehyde) resin, epoxy resin, joalo-joalo ho etsa liphahlo tse nang le likarolo tse peli. Ho e kenyelletsa penteng ea koloi ea boemo bo holimo ho ka boloka seipone sa eona se benyang ka nako e telele. E ka boela ea sebelisoa e le sekhomaretsi bakeng sa masela a maiketsetso le li-monomers tsa bongaka tsa polymer.
2. HEMA e sebelisetsoa ho hlahisa li-resin bakeng sa liphahlo, li-topcoats tsa likoloi le li-primers, hammoho le li-resin tsa photopolymer, liboto tsa khatiso, li-inks, li-gel (li-lenses tsa ho kopana) le liphahlo tsa thepa ea tinning, microscopy ea elektronike ea transmission (TEM) le optical microscopy (LM) embedding. li-reagents, haholo-holo bakeng sa disampole tsa hydration tsa "sensitive antigen sites". Metsi a masoeu joalo ka, a khomarela, a tšesaane ho feta metsi, 'me ho bonolo ho phunyeletsa ho feta resin leha e le efe kapa monoma. E sebelisoa ka ho khetheha bakeng sa mosebetsi oa masapo, lefufuru, 'me ho thata ho phunyeletsa lisele tsa semela.
3. Indasteri ea polasetiki e sebelisetsoa ho etsa li-resin tsa acrylic tse nang le lihlopha tse sebetsang tsa hydroxyl. Indasteri ea ho roala e sebelisoa hammoho le li-epoxy resin, diisocyanates, melamine formaldehyde resin, joalo-joalo ho hlahisa liphahlo tse peli tsa likarolo. Indasteri ea oli e sebelisoa e le tlatsetso bakeng sa ho hlatsoa oli. Indasteri ea elektronike e sebelisoa e le ntho e fokotsang metsi 'meleng bakeng sa li-microscopes tsa elektronike. Likhomaretsi tse sebelisoang indastering ea masela ho etsa masela. E sebelisoa e le reagent ea lik'hemik'hale ho chemistry ea tlhahlobo. Ntle le moo, e boetse e sebelisoa e le ntho e kenyang metsi bakeng sa ho kopanya lisebelisoa tsa bongaka tsa polymer, liphahlo tsa thermosetting le likhomaretsi.
Bokamoso baHEMA:
Bahlahlobisisi ba indasteri ba boletse hore ka lebaka la ts'ebetso ea eona e felletseng e felletseng, hydroxyethyl methacrylate hajoale e na le tlhokahalo e kholo ea likopo, haholo-holo mafapheng a liphahlo tsa bongaka le tsa maemo a holimo, ka tebello e ts'episang. Ho ntse ho na le menyetla ea nts'etsopele 'marakeng oa kamoso oa hydroxyethyl methacrylate. Lehlakoreng la tlhokahalo: Ka kholo e potlakileng ea tlhokahalo masimong a kang liphahlo le likhomaretsi, tšebeliso ea 2-hydroxyethyl methacrylate e ntse e eketseha butle-butle. Ka botsebi,HEMAthekenoloji ea tlhahiso le theknoloji ea tlhahiso ea polyether e ka ithuta ho e mong mabapi le moralo, lisebelisoa, ts'ebetso le ts'ebetso.Mabapi le ketane ea indasteri: nts'etsopele ea lihlahisoa tse phahameng tsa hydroxyethyl methacrylate li ka amahanya le lisebelisoa tse ka holimo tsa methacrylic acid le ethylene oxide, hammoho le lisebelisoa tsa ho roala holim'a metsi a tlaase. Ka nako e ts'oanang, hydroxyethyl methacrylate ke thepa ea bohlokoa e tala bakeng sa khoebo ea lintho tse bonahalang, ho netefatsa phepelo ea li-monomers tsa bohlokoa bakeng sa khoebo e tlaase, ho atolosa ketane ea indasteri, le ho eketsa boleng ba sehlahisoa. . E le ho kopanya karolo ea eona ea 'maraka, k'hamphani e entse qeto ea ho eketsa bokhoni ba eona ba tlhahiso ea thepa ea pele le ho tsoela pele ho hloekisa mokhoa oa pele oa litšila ho eketsa matla a eona a tlhahiso.
