Kodi zigawo zikuluzikulu za utomoni wa UV ndi ziti

UV utomonindiye chigawo chachikulu cha UV machiritso dongosolo.Ndi oligomer yomwe imatha kusintha thupi ndi mankhwala pakanthawi kochepa atatha kuwunikira kuwala kwa UV, ndikulumikizana mwachangu ndikuchiritsa.Pambuyo pochiritsa zokutira za UV, magwiridwe antchito a filimu yokutirayo amadalira kwambiri zinthu zake zazikulu zopanga filimu - utomoni wa UV, ndi magwiridwe antchito.UV utomoniimatsimikiziridwa ndi macromolecular polima omwe amapanga utomoni uwu.Mapangidwe a maselo, kulemera kwa maselo, kachulukidwe kaŵirikaŵiri ndi kutentha kwa magalasi a polima zidzakhudza momwe utomoni ukuyendera.Utoto wamtundu wamafuta wa UV uli ndi kulemera kwakukulu kwa mamolekyu ndi kukhuthala, kotero umakhala ndi zoperewera pakuyala ndi kuwongolera kachitidwe ka filimu.Acrylatediluent yogwira [1] imakhala ndi zomangira ziwiri zopanda unsaturated ndipo zimakhala ndi kukhuthala kochepa.Kuwonjezera pa njira yochiritsira ya UV kumatha kuchepetsa kukhuthala kwa utomoni, kukonza kachulukidwe ka utomoni wolumikizirana, ndikuwongolera magwiridwe antchito a filimu ya utomoni, motero amagwiritsidwa ntchito kwambiri.Komabe, mankhwala osokoneza bongo ambiri amakhala oopsa komanso amakwiyitsa khungu la munthu, mucous nembanemba ndi maso.Kuphatikiza apo, diluent ndizovuta kuchitapo kanthu pa kuyatsa kwa UV, ndipo chotsalira chotsaliracho chidzakhudza kwambiri ntchito yayitali ya filimu yochiritsa, yomwe imalepheretsa ntchito yake pakuyika zida zaukhondo wazakudya.

Kumwa madziUV utomoniamanena zaUV utomonizomwe zimasungunuka m'madzi kapena zimatha kumwazikana ndi madzi.Mamolekyu ake ali ndi kuchuluka kwa magulu a hydrophilic monga carboxyl, hydroxyl, amino, ether kapena magulu amide, komanso magulu a unsaturated monga acryloyl, methacryloyl kapena allyl magulu.Pakali pano, madziUtomoni wa UVmakamaka zikuphatikizapo madzi polyacrylate, waterborne polyester acrylate, waterborne epoxy acrylate ndi waterborne polyurethane acrylate.

Monga mtundu watsopano wa polima, hyperbranched polima ali ndi ozungulira dongosolo, ambiri yogwira mapeto magulu, ndipo palibe entanglement pakati unyolo maselo.Ma polima a Hyperbranched ali ndi maubwino osungunuka mosavuta, malo osungunuka otsika, ma viscosity otsika komanso kuchitapo kanthu kwakukulu.Chifukwa chake, magulu a acryloyl ndi magulu a hydrophilic amatha kuyambitsidwa kuti apangitse ma oligomers otetezedwa ndi UV, omwe amatsegula njira yatsopano yopangira madzi.Utomoni wa UV.
