Xabagta UV waxaa lagu polymerized iyadoo leh agab cayriin saaxiibtinimo deegaanka iyo teknoolajiyada cusub.Waxay leedahay qallafsanaan dhexdhexaad ah, biyo ku salaysan, ma laha wasakhowga VOC, sunta hoose, gubasho la'aanta, ku dhejinta warqadda, dabacsanaanta wanaagsan.Alaabta waxaa lagu qasi karaa biyo iyadoo loo eegayo baahida viscosity.Viscosity ee alaabtu waa dhexdhexaad, iyo khadku wuxuu ku fiican yahay daahan rullaluistemadka iyo nidaamka khad daabacaadda.Alaabtu waa hurdi waana caddahay.Daawaynta ka dib, filimka rinjigu aad buu u hufan yahay waxaana loo isticmaali karaa monomers saliid leh si loo helo adkeysi sare iyo iska caabin sare oo xoqan sifooyin kale oo ku yaal dusha sare ee muraayadaha aan organic iyo qalabka.Waxaa lagu talinayaa bacaha sigaarka, looxyada wareegga, dhalooyinka, qalabka, ceramics iyo alaabta kale.
UV resin function: viscosity hooseeya, gaar ahaan ku habboon UV khad-jet iyo daabacaadda 3D, oo leh qoyaan wanaagsan, mawqif hoose, maaddo adag oo sarreeya iyo hoos u dhac yar, dhejis wanaagsan oo dhalada iyo birta ah, caabbinta kiimikada, caabbinta biyaha karkaraya iyo caabbinta biyaha xumbo.kala duwan codsiga: UV khad-jet, 3D daabacaadda, UV khad muraayadda, hardware, UV khad dhoobada, UV alkali khad lagu dhaqo, galaas UV xabagta, iwm. ) hindise (ama photosensitizer) ayaa lagu daray.Marka la eego shucaaca iftiinka ultraviolet (250-300 nm) ee mawjada dhererka qaarkood, falcelinta polymerization ayaa isla markaaba sabab u ah inay dhamaystirto daaweynta.Xajiinta sawir-qaadista guud ahaan waa dareere, waxaana guud ahaan loo isticmaalaa in lagu sameeyo maaddooyin leh awood sare, iska caabin heerkul sare ah iyo biyuhu.
Xabagta UV waa qayb ka mid ah daahan UV, waana xabagta matrix ee daahan UV.Guud ahaan, waxay leedahay kooxo si dheeraad ah uga falcelin kara ama polymerize kara xaaladaha iftiinka, sida carbon double bond iyo epoxy group.Marka loo eego nooca dareeraha, xabagta UV waxa loo qaybin karaa nooc dareere ah oo loo yaqaanno UV resin iyo aqueous UV resins-ka dareeraha ah ee dareeraha ku salaysan kuma jiraan kooxo hydrophilic ah oo kaliya waxa lagu milmi karaa dareerayaasha organic, halka xabagta aqueous ay ka kooban yihiin kooxo badan oo hydrophilic ah ama qaybo biyo-biyood ah waxayna karaan lagu shubo, lagu kala firdhiyo ama lagu milmo biyo.Biyo-mareenada UV-ga waxa ay tixraacaan resins UV ee ku milmay biyaha ama lagu kala firdhi karo biyaha.Unugyadu waxay ka kooban yihiin tiro go'an oo ah kooxaha hydrophilic xoog leh, sida carboxyl, hydroxyl, amino, ether, acylamino, iwm., iyo kooxo aan saturated ahayn, sida acryloyl, Methacryloyl ama allyl.Geedaha UV-ga biyaha ka dhasha waxa loo qaybin karaa saddex nooc: nooca looshanka, nooca biyaha kala firdhiyo iyo nooca biyaha milmi kara Inta badan waxa ka mid ah saddex qaybood oo kala ah: waterborne polyurethane acrylate, waterborne epoxy acrylate iyo waterborne polyester acrylate.
