Hydroxyethyl acrylate
Incamake y'ibicuruzwa
Hydroxyethyl Acrylate (HEA) ni monomer ifite imikorere myinshi kandi ni ingenzi mu kubaka shimi ya polymer. Ifite polymerizable acrylic double bond hamwe na hydroxyl group reactive muri molecule imwe. Iyi miterere ituma ishobora kunyura muri copolymerization hamwe na monomers zitandukanye mu gihe inagira uruhare mu guhuza. Ni amazi asobanutse, adafite ibara cyangwa umuhondo woroshye kandi azwiho kongera imikorere y'ibicuruzwa bya polymeric bya nyuma, ndetse no mu gihe bikoreshejwe mu rugero ruto.

Porogaramu z'ingenzi
Imikorere ibiri ya HEA ituma iba ingenzi mu nganda nyinshi:
Irangi n'amabara:
Irangi rya Thermosetting: Irangi rya mbere rya monomer mu irangi ry’imodoka, inganda, n’ibikoresho. Itsinda rya hydroxyl rihuza na melamine-formaldehyde cyangwa polyisocyanate resins (muri irangi rya PU), ritanga ubukana bwiza, ubushobozi bwo kurwanya uburozi, no kurwanya mar.
Sisitemu Ivurwa n'Imirasire: Ikoreshwa nk'umusemburo ugabanya ubushyuhe n'urukiramende mu bisigazwa, inki, n'ibindi bikonjesha bivurwa na UV/EB. Ni ikintu cy'ingenzi mu gukora acrylate za urethane.
Abakora Photoresists na Photoreactive Polymers: Bakoreshwa mu gukora resins za photoresist zo gucapa no gukoresha ibikoresho by'ikoranabuhanga (semiconductors, LCDs).
Ibikoresho byo gufunga n'ibifunga:
Yongera imbaraga zo gufatana ku bintu bitandukanye, harimo ibyuma na pulasitiki.
Yongera ubucucike bw'imirongo, bigatuma habaho ubudahangarwa bw'ubushyuhe, ubudahangarwa bw'imiti, n'imbaraga zo gufatana mu byuma bikonjesha imiterere n'umuvuduko (PSAs).
Imyenda n'Insinga:
Ikoreshwa nk'ikintu kimwe mu bikoresho bifasha mu gutunganya fibre no mu gusiga imyenda kugira ngo ikomeze kumera neza, idacika iminkanyari, kandi irambe.
Gutunganya impapuro:
Bishyirwa mu buryo bwo gusiga kugira ngo byongere imbaraga z'amazi n'izumye, birwane n'amazi, kandi bikongere ubushobozi bwo gucapa.
Porogaramu zihariye:
Inganda zitunganya amavuta: Ikora nk'ikintu gikoreshwa mu gukora ibikoresho by'isabune n'ibindi bikoresho bisukura.
Ibyuma by'ikoranabuhanga: Bikoreshwa nk'ikintu gifasha mu gukura amazi mu mubiri mu gutegura icyitegererezo cya mikorosikope.
Ubutabire bw'isesengura: Bukora nk'ikintu kigabanya ubukana bw'ibinyabutabire kandi nk'igice cy'ibintu bivanga amazi.
Ibintu by'ingenzi n'inyungu
Imikorere ibiri: Itsinda rya acrylate rituma habaho copolymerization, mu gihe itsinda rya hydroxyl rituma habaho guhuza no guhindura imiti.
Imikorere myiza: Itanga kuramba gukomeye, kudakoresha imiti, no gufatana na polimeri za nyuma.
Ikora neza cyane: Ikora copolymerize neza hamwe na acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile, n'ibindi.
Uburyo bwo gukora ibintu bitandukanye: Bikwiriye uburyo butandukanye bwo gukora polymerization, harimo umuti, emulsion, na suspension polymerization.
Imikorere Inoze: Itera imbere cyane mu miterere y'ibicuruzwa ndetse no ku rwego rwo hasi rwo kubikoresha (ubusanzwe 2-10%).
Ubushyuhe buke: Bukora nk'umusemburo mwiza mu buryo bushobora kuvurwa n'imirasire, bugafasha kugabanya ubushyuhe bw'imvange y'ibimera hadakoreshejwe ibintu bihindagurika by'umwimerere (VOCs).
Gucunga no Kubika
Ubushyuhe bwo kubika: Bika ahantu hakonje kandi hafite umwuka mwiza. Ubushyuhe busabwa kubikwa ni hagati ya 2°C na 25°C (36°F na 77°F). Irinde ubukonje n'ubushyuhe bwinshi.
Inhibitor: Irimo MEHQ inhibitor kugira ngo irinde polymerization yihuta. Iyi inhibitor isaba ko umwuka wa ogisijeni uba uhari kugira ngo ikore; bityo, kubika mu kirere kidakora neza (urugero, azote padding) ni ingenzi kugira ngo ikomeze kubaho igihe kirekire.
Igikoresho: Bika mu bikoresho bifunze neza bikozwe mu byuma bitarangwamo ifu, icyuma gikozwe muri phenolic resin, cyangwa polyethylene. Birinde urumuri.
Igihe cyo kubika: Ubusanzwe amezi 6 kugeza kuri 12 uhereye igihe byakorewe iyo bibitswe mu buryo busabwa.
Uburyo bwo kuyikoresha: Ikoreshe neza kandi ikoresheje uburyo buhagije bwo guhumeka no kugenzura imikorere y’ikoranabuhanga. Irinde ko ikora ku ruhu, amaso, n’imyenda. Ambara ibikoresho byo kwirinda byihariye (PPE), harimo uturindantoki tudakoresha imiti, amadarubindi yo kwirinda, n’imyenda yo kwirinda.
