Hydroxypropyl acrylate
Kakaretso ea Sehlahisoa
Hydroxyethyl Acrylate (HEA) ke monomer e sebetsang ka mokhoa o fapaneng le motheo oa bohlokoa k'hemistri ea polymer. E na le polymerizable acrylic double bond le sehlopha sa reactive hydroxyl ka har'a molek'hule e le 'ngoe. Sebopeho sena se e lumella ho feta habonolo copolymerization ka mefuta e mengata ea li-monomer ha ka nako e ts'oanang e boetse e nka karolo liketsong tsa ho kopanya. Ke mokelikeli o hlakileng, o se nang 'mala ho isa ho o mosehla o bobebe 'me o tsejoa ka ho ntlafatsa haholo litšobotsi tsa ts'ebetso ea lihlahisoa tsa ho qetela tsa polymeric, leha li sebelisoa ka bongata bo bonyenyane.

Litšebeliso tse ka Sehloohong tsa Hydroxypropyl Acrylate
Tshebetso e habeli ya HPA e e dumella ho sebediswa diindastering tse fapaneng. Mosebetsi wa yona o ka sehloohong ke ho sebetsa jwalo ka mohlohlelletsi ya arabelang le mofani wa sebaka sa ho hokahanya.
Liaparo le Enke:
Liaparo tsa Thermosetting: E sebetsa e le co-monomer ho liaparo tsa likoloi, tsa indasteri le tsa coil. E hokahana le melamine, isocyanate, kapa epoxy resins, e leng se fellang ka lifilimi tse thata haholo, tse hanyetsang lik'hemik'hale, tse hanyetsang mar le tse benyang haholo.
Mekhoa e Phekoang ke Mahlasedi: E sebelisoa ho lipente, lienke le likhomaretsi tse phekoang ke UV/EB. Sehlopha sa hydroxyl se lumella ho etsoa ha li-acrylate tsa urethane tse nang le thepa e ntlafalitsoeng.
Li-Resins tsa Photoresist: Karolo ea bohlokoa li-resins tse utloang foto bakeng sa tlhahiso ea semiconductor le ponts'o.
Likhomaretsi le Litiiso:
E ntlafatsa ho khomarela lintho tse thata ho hokahanngoa joalo ka litšepe le polasetiki e phekotsoeng.
E ntlafatsa bongata ba likhokahano, e leng se lebisang ho ntlafatseng ho hanyetsa mocheso, ho hanyetsa lik'hemik'hale, le matla a ho kopana ha likhomaretsi tse utloang khatello (PSAs) le likhomaretsi tsa sebopeho.
Masela le Likhoele:
E sebelisoa e le sesebelisoa sa kalafo ea faeba ho fetola likhoele tsa maiketsetso, ho ntlafatsa ho daea, thepa ea ho thibela ho fetoha ha static le ho monya mongobo.
Li-resin le Lipolasitiki tsa Maiketsetso:
Jwalo ka mofetoledi wa acrylic le di-resin tse ding tsa maiketsetso, Hydroxypropyl acrylate e fana ka kganyetso e phahameng ya boemo ba lehodimo, kganyetso ya tshusumetso le ho tenyetseha.
Hydroxypropyl Acrylate Ditshebediso tse ding:
Ho Sebetsa Pampiri: E le karolo ea resin e matla le ea ho roala.
Lik'hemik'hale tsa Phekolo ea Metsi: Li sebelisoa ho kopanyeng li-scale le li-corrosion inhibitors.
Litlolo tse Ekelitsoeng: Li sebetsa e le selelekela sa ntlafatso ea index ea viscosity le li-dispersant.
Litšobotsi tsa Bohlokoa tsa Hydroxypropyl Acrylate le Melemo
Reaction e Hlollang: Sehlopha sa acrylate se kopanya habonolo di-monomer tse ngata tsa vinyl le acrylic (mohlala, methyl methacrylate, butyl acrylate, styrene, acrylonitrile).
Bokgoni bo Matla ba ho Kopanya Dikopano: Sehlopha sa pendant hydroxyl se arabela habonolo le diisocyanate, di-anhydride, le di-amino resins (mohlala, melamine), se nolofalletsang ho thehwa ha marangrang a polymer a mahlakore a mararo a tiileng.
Ho Khomarela ho Ntlafalitsoeng: Ho khothalletsa ho khomarelana ho matla le li-substrate tse fapaneng.
Ntlafatso ea ho Tšoarella: E tlatsetsa ho hanyetseng lik'hemik'hale, li-solvents, boemo ba leholimo le khanya ea UV ka tsela e ikhethang.
Ho feto-fetoha ha maemo: E ka sebelisoa mefuteng e mengata ea lits'ebetso tsa polymerization, ho kenyeletsoa tharollo, emulsion, suspension le polymerization e kholo.
Bokgoni ba Tshebetso: E fana ka dintlafatso tse kgolo thepeng ya ho qetela ya sehlahiswa esita le maemong a tlase a tshebediso (hangata 1-10%).
Ho sebetsana le ho Boloka
Polokelo: Boloka sebakeng se pholileng, se lefifi, le se nang le moea o kenang hantle. Boloka lijana li koetsoe ka thata. Mocheso o khothaletsoang oa polokelo o pakeng tsa 15°C le 25°C (59°F le 77°F).
Inhibitor: E na le MEHQ (Methoxyphenol) e le inhibitor ea polymerization ho thibela ho iketsetsa polymerization nakong ea polokelo le lipalangoang. Ho bohlokoa ho boloka inhibitor ena bakeng sa botsitso.
Ho sebetsana le tsona: Qoba ho kopana le mocheso, litlhase, malakabe a bulehileng, le lintho tse matlafatsang oksijene. Sebelisa ka moea o lekaneng 'me u apare lisebelisoa tse loketseng tsa tšireletso ea botho (PPE), ho kenyeletsoa liatlana tse sa haneleng lik'hemik'hale, likhalase tsa tšireletso le liaparo tse sireletsang.
Bophelo ba Shelofo: Hangata ke dikgwedi tse 12 ho tloha ka letsatsi la tlhahiso ha e bolokwa tlasa maemo a kgothalletswang.
