UV resin, oo sidoo kale loo yaqaanno resin photosensitive, waa oligomer kaas oo ku dhici kara isbeddelo jidheed iyo kiimiko ah muddo gaaban ka dib marka la soo bandhigo iftiinka, ka dibna isku xira oo xoojiya waxay samayn kartaa UV, sida bonds double ama epoxy groups.
Xabagta UV waa resin-ka matrix ee dahaarka UV.Waxaa lagu daray sawir qaade, dareere firfircoon iyo waxyaabo lagu daro oo kala duwan si loo sameeyo daaha UV
Xabbad UV, oo sidoo kale loo yaqaanno resin photosensitive, ayaa leh sifooyinka soo socda: oligomer-isku-xidhan oo la daweeyay.Xabagta UV waa resin-ga matrix ee daahan UV, faa'iidooyinkeeduna waa sida soo socota:
(1) Xawaaraha daaweynta degdega ah iyo waxtarka wax soo saarka sare;
(2) Isticmaalka tamarta sare iyo ilaalinta tamarta;
(3) Iskudhisyo dabiici ah oo aan degganayn (VOC), deegaan ahaan u wanaagsan;
(4) Waxaa lagu dahaadhay karaa noocyo kala duwan, sida warqad, caag, maqaar, bir, dhalo, dhoobo, iwm;
Xabagta UV waa qaybta ugu weyn ee dahaarka UV iyo xargaha matrixka ee daaha UV.Guud ahaan waxa ay leedahay kooxo dheeraad ah oo ka falceliya ama polymerize xaaladaha iftiinka, sida carbon double bonds, epoxy groups, iwm. Marka loo eego noocyada kala duwan ee dareeraha, xabagta UV waxa loo qaybin karaa dareeraha UV-ku salaysan ee dareeraha ah kuma jiraan kooxaha hydrophilic waxayna kaliya ku milmi karaan dareerayaasha organic, halka resins-ku-salaysan biyaha ay ka kooban yihiin kooxo badan oo hydrophilic ama qaybo silsilad hydrophilic ah waxaana lagu dami karaa, lagu kala firdhiyey ama lagu milmi karaa biyaha.
Kala soocidda
Xabagta UV ku salaysan millatariga
Caadi ahaan dareeraha ku salaysan UV resins inta badan waxaa ka mid ah: UV polyester unsaturated, UV epoxy acrylate, UV polyester acrylate, UV polyester acrylate, UV xabagta acrylic saafi ah, UV resin UV epoxy, UV silicone oligomer.
Biyo-galeenka UV-ga
Xabagta UV ee biyaha ka dhasha waxay tixraacaan xabagta UV ee lagu milmi karo 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 sidoo kale kooxo aan saturated ahayn, sida acryloyl, methacryloyl ama allyl.Geedaha UV ee biyaha ka dhasha waxa loo qaybin karaa saddex nooc: nooca looshanka, nooca biyaha kala firdhisan yahay iyo nooca biyaha lagu milmo Waxay inta badan ka kooban tahay saddex qaybood: waterborne polyurethane acrylate, waterborne epoxy acrylate iyo waterborne polyester acrylate.
Qaybaha codsiga ee ugu weyn ee xabagta UV waxaa ka mid ah daahan UV, khadadka UV, UV-dhesives, oo ay ku jiraan daahan UV waa kuwa ugu ballaaran loo isticmaalo, oo ay ku jiraan noocyada soo socda ee daahan UV waterborne daahan UV, daahan UV maqaar, UV daahan fiber indhaha, UV. dahaarka biraha, dahaarka UV warqad glazing, daahan caag UV, daahan alwaax UV.
