1, Epoxy acrylic resin ndiyo yomwe imagwiritsidwa ntchito kwambiri komanso imagwiritsidwa ntchito kwambiri ndi utomoni wa UV pakati pa makasitomala athu onse.Epoxy acrylic resin amagwiritsidwa ntchito kwambiri ngati utomoni waukulu wa pepala lochiritsa, matabwa, pulasitiki ndi zitsulo zokutira, inki yochiritsa komanso zomatira zowala chifukwa cha njira yake yosavuta yopangira, gwero losavuta la zopangira, mtengo wotsika, kuthamanga kwachangu kuchiritsa, kuuma kwakukulu, gloss yapamwamba, kukana kwambiri kwamankhwala, kukana kutentha kwabwino komanso mphamvu zamagetsi.The epoxy acrylic resin opangidwa ndi lankelu makamaka amaphatikizapo zosiyanasiyana kusinthidwa epoxy acrylic resins, amene ali ndi makhalidwe osiyana magawo osiyana.
2, Polyurethane akiliriki utomoni, amenenso ankagwiritsa ntchito komanso kuchuluka kwa UV utomoni.Polyurethane acrylic resin imagwiritsidwa ntchito kwambiri pamapepala ochiritsa opepuka, matabwa, pulasitiki ndi zitsulo zokutira, inki yochiritsa komanso zomatira zowala chifukwa chazinthu zake zonse, monga kukana kwamphamvu komanso kusinthasintha kwa filimu yochiritsidwa, kukana bwino kwamankhwala, kukana mphamvu ndi mphamvu zamagetsi, ndi kumamatira bwino kwa pulasitiki ndi magawo ena.Mitundu yayikulu ya utomoni wa acrylic wa polyurethane wopangidwa ndi lankelu umaphatikizapo utomoni wonunkhira komanso aliphatic polyurethane acrylic.
3, Polyester acrylic utomoni ndiwonso amagwiritsidwa ntchito kwambiri UV utomoni.Chifukwa utomoniwo umakhala ndi fungo lochepa, kupsa mtima pang'ono, kusinthasintha bwino komanso kunyowa kwa pigment, nthawi zambiri amagwiritsidwa ntchito popaka utoto wochiritsa komanso inki yochiritsa yopepuka pamodzi ndi epoxy acrylic resin ndi polyurethane acrylic resin.
4, Amino acrylic resin nthawi zambiri amagwiritsidwa ntchito mu zokutira za UV ndi inki za UV ndi epoxy acrylic resin ndi polyurethane acrylic resin chifukwa cha kukana kwake kutentha ndi kukana kwa nyengo, kukana mankhwala abwino komanso kuuma kwakukulu.
Utoto wa UV, womwe umadziwikanso kuti photosensitive resin, ndi oligomer yomwe imatha kusintha mwachangu mthupi ndi mankhwala pakangopita nthawi yochepa itatha kuyatsidwa ndi kuwala, kenako ndikudutsana ndikuchiritsa.UV utomoni ndi photosensitive utomoni ndi otsika wachibale utomoni.Ili ndi magulu ochitapo kanthu omwe amatha kuchita UV, monga ma unsaturated double bond kapena epoxy group.
Utoto wa UV ndi utomoni wa matrix wa zokutira za UV.Zimaphatikizidwa ndi photoinitiator, diluent yogwira ntchito ndi zowonjezera zosiyanasiyana kuti apange zokutira za UV.
Ubwino wa utomoni wa UV:
(1) Kuthamanga kwachangu komanso kuchita bwino kwambiri;
(2) Kugwiritsa ntchito mphamvu kwambiri komanso kupulumutsa mphamvu;
(3) Zochepa za organic volatile matter (VOC) komanso zachilengedwe;
(4) Itha kukhala yokutidwa ndi magawo osiyanasiyana, monga pepala, pulasitiki, zikopa, zitsulo, galasi, zoumba, etc;
Kuwunika kwa chilinganizo cha zokutira za UV kukuwonetsa kuti utomoni wa UV ndiye gawo lalikulu kwambiri pakupaka kwa UV, ndipo ndiye utomoni wa matrix mu zokutira za UV.Nthawi zambiri, ili ndi magulu omwe amachitiranso kapena ku polymerize pansi pa mikhalidwe yowala, monga carbon carbon double bond, epoxy group, etc. Malinga ndi mitundu yosiyanasiyana ya zosungunulira, ma resins a UV akhoza kugawidwa muzosungunulira zochokera ku UV ndi ma resins a UV a Waterborne.Zosungunulira zosungunulira sizikhala ndi magulu a hydrophilic ndipo zimatha kusungunuka muzosungunulira za organic, pomwe utomoni wamadzi umakhala ndi magulu ambiri a hydrophilic kapena magawo a hydrophilic unyolo, omwe amatha kusungunulidwa, omwazika kapena kusungunuka m'madzi.
Zosungunulira zochokera ku UV utomoni:
Mafuta osungunulira omwe amagwiritsidwa ntchito kwambiri a UV makamaka amaphatikizapo: poliyesitala ya UV unsaturated, UV epoxy acrylate, UV polyurethane acrylate, UV polyester acrylate, UV polyether acrylate, UV pure acrylic resin, UV epoxy resin, UV silikoni oligomer.
Kuwunika kwapang'onopang'ono kwa utomoni wa UV kukuwonetsa kuti minda yayikulu yogwiritsira ntchito ndi: zokutira za UV, inki ya UV, guluu la UV, ndi zina zambiri. Pakati pawo, zokutira za UV ndizomwe zimagwiritsidwa ntchito kwambiri, kuphatikiza mitundu iyi: zokutira zotengera madzi a UV, zokutira za ufa wa UV. , zokutira zachikopa za UV, zokutira za UV optical fiber, zokutira zitsulo za UV, zokutira zopukutira za UV, zokutira zapulasitiki za UV ndi zokutira zamatabwa za UV.
