UV cobyog polymerized nrog ib puag ncig-phooj ywg raw cov ntaub ntawv thiab cov thev naus laus zis tshiab los tsim qhov nruab nrab hardness, dej-raws li VOC dawb, tsis muaj toxicity, incombustible, zoo adhesion rau ntawv, zoo saj zawg zog thiab zoo ntau lawm cov khoom.Lub viscosity ntawm cov khoom tuaj yeem diluted nrog dej raws li qhov xav tau viscosity.Cov khoom nrog zoo inking kev ua tau zoo nyob rau hauv cov menyuam txheej thiab luam ntawv number case tshuab yog yellowish thiab meej.Tom qab kho, cov xim zaj duab xis yog ci thiab pob tshab, uas tuaj yeem siv nrog qee cov roj monomers kom tau txais cov tawv tawv thiab siab khawb tsis kam, Nta: tsis tshua muaj viscosity tshwj xeeb hloov polyurethane acrylic UV resin, uas muaj qhov tshwj xeeb adhesion, dej boiling kuj, dej. npuas tsis kam thiab lwm yam ntxwv ntawm cov iav inorganic thiab kho vajtse.Nws raug nquahu kom siv rau hauv cov ntim luam yeeb, Circuit Court boards, iav, hardware, ceramics thiab lwm yam ntaub ntawv.
UV resin muaj nuj nqi: tsis tshua muaj viscosity, tshwj xeeb tshaj yog tsim rau UV inkjet,3D luam ntawvPigment nrog zoo wettability, tsis muaj viscosity, siab cov ntsiab lus thiab tsawg shrinkage, zoo adhesion rau iav thiab hlau, tshuaj tiv thaiv, dej boiling kuj thiab dej npuas kuj Daim ntawv thov ntau yam: UV inkjet, 3D luam ntawv, UV number case rau iav, kho vajtse, UV number case ntawm ceramic, UV alkali ntxuav number case, iav UV kua nplaum, thiab lwm yam., UV resin, muaj li ntawm polymer monomer thiab prepolymer, Photoinitiator (los yog photosensitizer) ntxiv.Nyob rau hauv lub irradiation ntawm ib tug tej yam wavelength ntawm ultraviolet lub teeb (250-300 nm), polymerization cov tshuaj tiv thaiv tam sim ntawd los ua kom tiav cov curing.Photosensitive resin feem ntau yog kua, uas feem ntau yog siv los ua cov ntaub ntawv nrog lub zog siab, kub tsis kam thiab tsis muaj dej.
UV resin yog ib feem ntawm UV txheej thiab matrix resin hauv UV txheej.Nws feem ntau muaj cov pab pawg uas txuas ntxiv los yog polymerize nyob rau hauv lub teeb, xws li carbon carbon ob daim ntawv cog lus, epoxy pawg, thiab lwm yam.UV resinstuaj yeem muab faib ua hnyav raws li UV resins thiab dej-raws liUV resinsraws li cov kuab tshuaj sib txawv.Cov kuab tshuaj raws li cov resins tsis muaj pawg hydrophilic thiab tuaj yeem tsuas yog soluble hauv cov kuab tshuaj organic, thaum cov dej-raws li cov resins muaj ntau pawg hydrophilic lossis hydrophilic chain segments, uas tuaj yeem ua emulsified, tawg lossis yaj hauv dej, Waterborne UV resin hais txogUV cobuas tuaj yeem yaj hauv dej lossis dispersed nrog dej.Cov molecule muaj qee qhov muaj zog hydrophilic pawg, xws li carboxyl, hydroxyl, amino, ether, acylamino, thiab lwm yam, nrog rau cov pab pawg tsis txaus, xws li acryloyl, methacryloyl lossis allyl.Waterborne UV ntoo tuaj yeem muab faib ua peb hom: tshuaj pleev, dej dispersible thiab dej-soluble.Lawv feem ntau suav nrog peb pawg: dej-yob polyurethane acrylate, Waterborne epoxy acrylate thiab waterborne polyester acrylate.
