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, mapolanka a khatiso, li-inks, gel (li-lenses tsa puisano) le liphahlo tsa thepa ea tinning, microscopy ea elektronike ea transmission (TEM) le optical microscopy (LM) embedding reagents, haholo-holo li-antigen tsa libaka. 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 ho ea ka 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 holimo tsa methacrylic acid le ethylene oxide, hammoho le lisebelisoa tsa ho roala metsi tse theohileng tlaase. Ka nako e ts'oanang, hydroxyethyl methacrylate ke thepa ea bohlokoa e tala bakeng sa khoebo ea thepa e ka holimo, 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.
