UV yekurapa tekinoroji imhando yemhando yepamusoro-inoshanda, kuchengetedza kwezvakatipoteredza, kuchengetedza-simba uye yepamusoro-soro zvinhu zvepasi tekinoroji.Iyo inozivikanwa setekinoroji nyowani yegreen indasitiri muzana ramakore rechi21.Nekuvandudzwa kwesainzi uye tekinoroji, kushandiswa kweUV kurapa tekinoroji kwakagadziridzwa kubva kumabhodhi akadhindwa ekutanga uye mafotoresist kusvika kune UV ekurapa majasi, ingi nemanamira.Nzvimbo yekunyorera yanga ichikura, ichigadzira indasitiri itsva.
Zvigadzirwa zvekurapa zveUV zvinowanzo kupatsanurwa kuita majai eUV, maingi eUV uye zvinonamira zveUV.Chinhu chavo chikuru ndechekuti vane kukurumidza kuporesa mwero, kazhinji pakati pemasekondi mashoma uye makumi emasekonzi, uye inokurumidza inogona kurapwa mukati me 0.05 ~ 0.1s.Ndiwo anokurumidza kuomesa uye kurapa pakati peakasiyana machira, ingi uye anonamira parizvino.
Kurapa kweUV kunoreva kurapa kweUV.UV ndiyo chidimbu cheChirungu che UV.Kurapa kunoreva maitiro ekuti zvinhu zvinoshanduka kubva kumamorekuru kusvika kumapolima.Kurapa kweUV kunowanzo kunoreva mamiriro ekurapa kana zvinodiwa zvekupotera (pendi), ingi, zvinonamira (glues) kana zvimwe zvisimbiso zvehari zvinoda UV kurapwa, izvo zvakasiyana nekupisa kupisa, kurapa neanonamira (anorapa), kurapa kwechisikigo, nezvimwe. [1].
Izvo zvakakosha zveUV kurapa zvigadzirwa 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 maoligomers aya akafanana ndezvekuti ese ane Unsaturated double bond resins anoverengerwa nerection rate yemahara radical polymerization: acryloyloxy > methacrylyloxy > vinyl > allyl. Naizvozvo, maoligomers anoshandiswa mumahara radical UV kurapa anonyanya akasiyana acrylic resins, senge epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, acrylate resin kana vinyl resin, uye anonyanya kushandiswa epoxy acrylate resin, polyurethane acrylate resin uye polyester acrylic resin.Aya matatu resin anounzwa muchidimbu pazasi.
Epoxy acrylate
Epoxy acrylic acid kukosha ndiyo inonyanya kushandiswa uye yakakura huwandu hweUV kurapa oligomer parizvino.Yakagadzirirwa kubva epoxy resin uye (meth) acrylate.Epoxy acrylates inogona kukamurwa kuita bisphenol A epoxy acrylates, phenolic epoxy acrylates, modified epoxy acrylates uye epoxidized acrylates maererano nemaitiro avo emhando, uye bisphenol A epoxy acrylates 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 yerapi rekurapa bepa, huni, mapurasitiki uye simbi coatings, uye zvakare seyo huru resin yekuvhenekesa inki uye mwenje unonamira.
Polyurethane acrylate
Polyurethane acrylate (PUA) imwe yakakosha UV inorapika 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 echigadzirwa mabhureki parizvino, uye anoshandiswa zvakanyanya muUV yekurapa machira, ingi uye anonamira.
Polyester Acrylate
Polyester acrylate (PEA) zvakare yakajairika oligomer, iyo inogadzirwa kubva yakaderera molecular uremu polyester glycol neacrylate.Polyester acrylate inoratidzirwa nemutengo wakaderera uye yakaderera viscosity.Nekuda kwekuderera kwayo viscosity, polyester acrylate inogona kushandiswa seiri oligomer uye inoshanda diluent.Mukuwedzera, akawanda polyester acrylates ane kunhuhwirira kwakaderera, kushatirwa kwakaderera, kushanduka 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, kuvandudza mwero wekurapa, asi zvakare inovandudza kunamatira, kupenya uye kupfeka kuramba.
Anoshanda diluents anowanzo ane reactive mapoka, anogona kunyungudutsa uye kunyungudutsa oligomers, uye kuita basa rakakosha mu UV kurapa maitiro uye firimu zvinhu.Zvinoenderana nenhamba yemapoka anoshanda, 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 zvakadai se trimethylolpropane triacrylate, etc. [2].
Initiator ine simba rakakosha pachiyero chekurapa kweUV kurapa zvigadzirwa.Mune UV kurapa zvigadzirwa, huwandu hwephotoinitiator hunowanzo 3% ~ 5%.Uye zvakare, pigment uye mafiller ekuwedzera anewo akakosha pakuita kwekupedzisira kweUV yakarapwa zvigadzirwa.
