Kuwongolera kwa Waterborne UV kuchiritsa utomoni kukubwera

UV ndi mtundu wa zokutira zomwe zimatha kuchiritsa mwachangu kukhala filimu mumasekondi pang'ono ndi kuwala kwa ultraviolet (UV).Zotchingira za UV zimakulungidwa zokha ndikupopera pa bolodi la mipando kudzera pamakina ndi zida.Pansi pa kuyatsa kwa kuwala kwa ultraviolet, imathandizira kuwonongeka kwa woyambitsa, imapanga ma free radicals, imayambitsa resin reaction, ndipo nthawi yomweyo imalimba kukhala filimu popanda kusungunuka kwa zosungunulira.Choncho, ndi bwino, wobiriwira ndi chilengedwe wochezeka.

Pansi pa hydration wamba, zokutira za Waterborne UV zimagwiritsidwanso ntchito bwino mumitengo, pulasitiki, kusindikiza, mankhwala atsiku ndi tsiku ndi magawo ena chifukwa chaubwenzi wawo wachilengedwe komanso ubwenzi womanga.Zida zopangira zimagwira ntchito yofunika.Kupitilira kwatsopano kwa magwiridwe antchito, mawonekedwe ndi njira zothetsera zokutira zokhala ndi madzi zimalimbikitsa njira ya resin hydration.

1 epoxy acrylate / polyurethane acrylate composite system

Photosensitive oligomer ndiye gawo lalikulu la utomoni wochiritsidwa ndi UV, womwe umatsimikizira zomwe zimakhala ndi utomoni wochiritsidwa.Mitundu yonse ya utomoni wa matrix ili ndi zabwino zake zosasinthika, koma idzakhala ndi zolakwika.Mwachitsanzo, filimu yochiritsa ya epoxy resin imakhala yolimba kwambiri, yomatira bwino, yonyezimira kwambiri komanso yosakanizidwa bwino ndi mankhwala, koma ili ndi vuto losasinthika bwino.Chitsanzo china ndi chakuti utomoni wopangidwa ndi polyurethane uli ndi zinthu zabwino kwambiri monga kukana kuvala komanso kukana kukanda, koma kukana kwake nyengo sikukwanira.Ofufuza amagwiritsa ntchito njira zosakaniza kapena zosakanizidwa kuti aziphatikiza ziwirizo, kuti apangitse kuchepa kwa utomoni umodzi ndikupanga dongosolo lomwe lili ndi mawonekedwe abwino kwambiri.

2 dendritic kapena hyperbranched system

Ma dendrimer okhala ndi madzi otetezedwa ndi UV kapena ma oligomer okhala ndi ma hyperbranched ndi mtundu watsopano wa ma polima okhala ndi mawonekedwe ozungulira kapena ozungulira komanso osalumikizana pakati pa unyolo wa maselo.Komanso, mawonekedwe a polima okhala ndi nthambi zambiri amakhala ndi magulu ambiri omaliza.Magulu omalizirawa omwe akugwira ntchito amasinthidwa kuti asinthe zinthu za polima ndikuziyika kumadera ena.Poyerekeza ndi ma polima ozungulira omwe ali ndi kulemera kofanana kwa ma molekyulu, ma oligomer okhala ndi ma hyperbranched ali ndi zinthu zabwino kwambiri monga malo otsika osungunuka, kukhuthala kotsika, kusungunuka kosavuta komanso kuchitanso bwino kwambiri.Ndiwo zida zabwino zopangira madzi opangira ma matrix resins.The madzi ofotokoza hyperbranched poliyesitala wapangidwa polyhydroxy ntchito aliphatic poliyesitala monga pachimake angathe kuchepetsa dilution madzi ndi kusonyeza zabwino mamasukidwe akayendedwe kuchepetsa zotsatira chifukwa cha kusungunuka kwake madzi abwino ndi otsika mamasukidwe akayendedwe.

3 epoxy soya mafuta acrylate

Mafuta a soya epoxy ali ndi ubwino wake wotsika mtengo, chitetezo cha chilengedwe, unyolo wautali wa ma molekyulu ndi kachulukidwe kakang'ono ka crosslinking.Ikhoza kusintha kwambiri kusinthasintha ndi kumamatira kwa zokutira.M'zaka zaposachedwapa, wakhala kafukufuku hotspot m'munda wa zokutira kunyumba ndi kunja.Kupambana kwabwino kwachitika mu epoxy soya mafuta acrylate ndi kusinthidwa epoxy soya mafuta acrylate UV free radical kuchiritsa zokutira ku China.Kampani ya Cub ku United States yachita malonda, monga ebercy860.Kaphatikizidwe ka epoxy soya mafuta acrylate nthawi zambiri ndi semi ester kusinthidwa njira, yomwe ndi esterificate epoxy soya mafuta ndi acrylic acid.
