Kodi ntchito ya ma catalyst mu self polymerization reaction ya hydroxyethyl acrylate ndi yotani?
Kuti hydroxyethyl acrylate ichitike, kutentha koyenera kumafunika choyamba. Kawirikawiri, kutentha komwe kumafunikira kuti hydroxyethyl acrylate ipange polymer. ZABWINO ili pakati pa 30°C ndi 60°C. Ngati kutentha kuli kotsika kwambiri, kuyambikako kudzakhala kochedwa kwambiri kapena sikudzachitika. Ngati kutentha kuli kokwera kwambiri, kuyambikako kungakhale koopsa kwambiri, zomwe zimapangitsa kuti zikhale zovuta kuwongolera njira yoyankhira zomwe zimapangitsa kuti zinthu zisayende bwino. Chifukwa chake, kuwongolera kutentha ndikofunikira kwambiri! Kuphatikiza pa kutentha, kuwala nakonso ndikofunikira. Hydroxyethyl acrylate imagwira ntchito kwambiri ndi kuwala kwa ultraviolet (UV), ndipo kuwala kwa UV kumatha kulimbikitsa kugawanika kwa ma bond ake awiri, motero kuyambitsa polymerization reaction. Pansi pa kuwala kwa UV, hydroxyethyl acrylate hea yodzipangira yokha idzakhala yachangu kwambiri. Ngati tigwiritsa ntchito nyali ya UV kapena kuiyika padzuwa, idzadzipangira yokha polymerization mwachangu. Tangoganizirani, pansi pa dzuwa, mamolekyu awa ali ngati kuvina, kuphatikizana mwachangu kuti apange zinthu zatsopano. Kuphatikiza pa kutentha ndi kuwala, kusankha chothandizira kumakhudzanso liwiro ndi zotsatira za self-polymerization reaction. Tidzawonjezera ma catalyst ena a peroxide, monga hydrogen peroxide, kapena azo compounds monga azobisisobutyronitrile (AIBN). Ma catalyst awa amatha kuchepetsa kutentha koyambira kwa self-polymerization reaction, zomwe zimapangitsa kuti ipitirire bwino ngakhale kutentha kotsika. Amachita ngati accelerator! Popanda catalyst, reaction ikhoza kukhala yochedwa kwambiri kapena yosachitika. Chifukwa chake, ntchito ya catalyst mu self-polymerization reaction siyinganyalanyazidwe.
