Chiedza chekurapa tekinoroji ndeyepamusoro-kushanda, kuchengetedza kwezvakatipoteredza, kuchengetedza-simba uye yepamusoro-soro zvinhu zvepasi tekinoroji.Iyo inozivikanwa setekinoroji nyowani yegreen indasitiri muzana ramakore rechi21.Nekuvandudzwa kwesainzi uye tekinoroji, kushandisa tekinoroji yekurapa mwenje yakagadziridzwa kubva pakatanga kudhindwa bhodhi uye photoresist kusvika pachiedza chekurapa coating, inki uye anonamira.Nzvimbo yekunyorera yanga ichikura uye yakagadzira indasitiri itsva.
Zvigadzirwa zvinonyanya kurapa zveUV majai eUV, maingi eUV uye zvinonamira zveUV.Chinhu chavo chikuru ndechekuti vane kukurumidza kurapa chiyero, kazhinji pakati pemasekondi mashoma uye makumi emasekonzi.Iyo inokurumidza inogona kurapwa mu 0.05 ~ 0.1s.Ndiwo anokurumidza kuomesa uye kurapa pakati peakasiyana machira, ingi uye anonamira parizvino.
Kurapa kweUV ndiko kurapa kweUV.UV ndiyo chidimbu cheChirungu che UV.Kurapa kunoreva maitiro ekuchinja zvinhu kubva kumamorekuru kusvika kumapolymer.Kurapa kweUV kunowanzo kunoreva mamiriro ekurapa kana zvinodiwa zvemapendi (pendi), ingi, zvinonamira (glues) kana zvimwe zvisimbiso zvepoto zvinoda kurapwa neUV, izvo zvakasiyana nekupisa kupisa, kubatanidza mumiririri (anorapa agent) kurapa, zvakasikwa. kurapa, nezvimwewo [1].
Izvo zvakakosha zvezvigadzirwa zvekurapa mwenje zvinosanganisira oligomers, inoshanda diluents, photoinitiators, additives uye zvichingodaro.Oligomer ndiyo mutumbi mukuru weUV inorapa zvigadzirwa, uye kuita kwayo kunotarisisa kuita kukuru kwezvinhu zvakarapwa.Naizvozvo, kusarudzwa uye dhizaini ye oligomer pasina mubvunzo chinhu chakakosha mukugadzirwa kweUV kurapa zvigadzirwa.
Izvo zvakafanana maoligomers aya ndezvekuti vese vane "Unsaturated double bond resins inoiswa zvinoenderana nerection rate yemahara radical polymerization: acryloyloxy> Methacryloyloxy> vinyl> allyl.Naizvozvo, maoligomers anoshandiswa mumahara radical light kurapa anonyanya marudzi ese ema acrylic resin, senge epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, acrylate resin kana vinyl resin, uye epoxy acrylate ndiyo inonyanya kushandiswa Acrylic resin, polyurethane. acrylic resin uye polyester acrylic resin.Aya matatu resin anounzwa muchidimbu pazasi.
Epoxy acrylate ndiyo inonyanya kushandiswa uye inoshandiswa mwenje kurapa oligomer.Yakagadzirirwa kubva epoxy resin uye (meth) acrylate.Epoxy acrylate inogona kukamurwa kuita bisphenol A epoxy acrylate, phenolic epoxy acrylate, yakagadziridzwa epoxy acrylate uye epoxidated acrylate zvinoenderana nerudzi rwechimiro.Bisphenol A epoxy acrylate ndiyo inonyanya kushandiswa.Bisphenol A epoxy acrylate imwe yemaoligomers ane kukurumidza kukurumidza kuporesa mwero.Iyo firimu yakarapwa ine kuoma kwepamusoro, kupenya kwakanyanya, kupikisa kwemakemikari kwakanaka, kupikisa kwakanaka kwekupisa uye zvinhu zvemagetsi.Mukuwedzera, bisphenol A oxygen exchange acrylate ine yakapfava yakapfava fomula uye mutengo wakaderera.Naizvozvo, inowanzoshandiswa seyakakura resin yechiedza chekurapa bepa, huni, mapurasitiki uye simbi coatings, pamwe neresin hombe yechiedza kurapa inki uye mwenje unonamira wekunamira.
Polyurethane acrylate
Polyurethane acrylate (PUA) chimwe chakakosha chiedza chekurapa oligomer.Iyo inogadzirwa neaviri-nhanho maitiro e polyisocyanate, refu-cheni diol uye hydroxyl acrylate.Nekuda kweakawanda zvimiro zve polyisocyanates uye refu-cheni diols, oligomers ane set zvivakwa anogadzirwa kuburikidza nemamorekuru dhizaini.Naizvozvo, iwo maoligomers ane akawanda chigadzirwa mabhureki parizvino, uye anoshandiswa zvakanyanya muchiedza chekurapa machira, ingi uye anonamira.
Polyester Acrylate
Polyester acrylate (PEA) zvakare yakajairika oligomer.Yakagadzirirwa ne acrylate yepasi molecular uremu polyester glycol.Polyester acrylate inoratidzirwa nemutengo wakaderera uye yakaderera viscosity.Nekuda kwekuderera kwayo viscosity, polyester acrylate inogona kushandiswa seiri oligomer uye inoshanda diluent.Pamusoro pezvo, polyester acrylates kazhinji ane kunhuhwirira kwakaderera, kushatirwa kwakaderera, kuchinjika kwakanaka uye pigment wettability, uye akakodzera pendi yemavara neingi.Kuti uvandudze chiyero chekuporesa, multifunctional polyester acrylate inogona kugadzirirwa;Amine yakagadziridzwa polyester acrylate haigone chete kuderedza pesvedzero yeokisijeni polymerization inhibition uye kuvandudza mwero wekurapa, asi zvakare inovandudza kunamatira, kupenya uye kupfeka kuramba.
Active diluents kazhinji ane reactive mapoka, ayo anogona kunyungudutsa nekunyungudutsa oligomers, uye kuita basa rakakosha muchiedza chekurapa maitiro uye firimu zvinhu.Zvinoenderana nenhamba yemapoka anogadziriswa arimo, akajairika monofunctional anoshanda diluents anosanganisira isodecyl acrylate, lauryl acrylate, hydroxyethyl methacrylate, glycidyl methacrylate, nezvimwe;Bifunctional active diluents zvinosanganisira polyethylene glycol diacrylate series, dipropylene glycol diacrylate, neopenyl glycol diacrylate, nezvimwewo;Multifunctional active diluents senge trimethylolpropane triacrylate, nezvimwe.
Initiator ine simba rakakosha pachiyero chekurapa kweUV kurapa zvigadzirwa.Mune UV kurapa zvigadzirwa, iyo yekuwedzera huwandu hwephotoinitiator inowanzo 3% ~ 5%.Uye zvakare, pigment uye mafiller ekuwedzera anewo akakosha maitiro pane ekupedzisira zvivakwa zveUV zvakarapwa zvigadzirwa.
