Majasi eUV anorapika ane zvakanakira kukurumidza kurapa kukurumidza, hushamwari kwezvakatipoteredza, kuchengetedza simba, mutengo wakaderera, nezvimwe.Kazhinji kutaura, iyo photosensitive liquid resin inogona kushandurwa zvakananga kuita resin yakapora nekuiisa pasi pemwenje weUV patembiricha yemhepo Kazhinji, haina kuvhurika organic komisheni kwezuva rimwe.Nekutarisisa kwakabhadharwa kune nyaya dzezvakatipoteredza, kutsvagisa, kusimudzira uye kushandiswa kweiyi nharaunda-inoshamwaridzika "girinhi" maitiro ari kuramba achiwedzera zvakadzama uye akakurumbira.Hydrophilic coating imhando yeanoshanda coating yakagadziridzwa nekukurumidza mumakore achangopfuura Inonyanya kushandiswa mualuminium uye aruminiyamu alloy zvigadzirwa, senge aruminiyamu mafins emhepo yekupisa kupisa exchanger.Iyo yechinyakare hydrophilic coating inowanzo gadzirwa nekubika iyo hydrophilic resin pa200C kwemakumi emasekonzi, wozorapa uye kuyambuka-kubatanidza kugadzira firimu.Kunyangwe iyo nzira yekugadzirira iine tekinoroji yakakura uye yakanaka hydrophilicity, inoshandisa simba rakakura, inonyungudutsa yakawanda organic zvinonyungudutsa uye ine isina kunaka nharaunda yekuvaka.Kugadzirira kweiyo yakachena organic hydrophilic coatings neUV kurapa uye muchinjika-kubatanidza haingotore mukana weyakanakira UV kurapwa, asi zvakare kusangana nezvinodiwa zve hydrophilicity.Mubepa rino, pfungwa itsva yekubatanidza yakagamuchirwa.Kubva pane yakaderera molecular uremu acrylate copolymer, photosensitive monomer yakaunzwa, uye ipapo photocurable muchinjika-yakabatanidzwa firimu yakaumbwa kugadzirira hydrophilic coatings.Mhedzisiro yekuiswa kweGMA, monomer ratio, inoshanda diluent mhando uye zvirimo pane hydrophilicity uye kushorwa kwemvura kwemajasi kwakaongororwa.
UV zvinorapika zvinhu zvinowanzo hydrophobic, inowirirana zvakanyanya nekuumbwa kwemaitiro avo.Photoinitiators inofanirwa kushandiswa mune UV yekurapa fomula.Dzimwe nguva, kuti uwedzere kurapa kwepamusoro, zvimwe zvinowedzera kusimudzira kurapa kwepamusoro zvichawedzerwa.Aya mafotoinitiators uye ekuwedzera anowanzo hydrophobic, uye zvigadzirwa zvekuora zvemafotoinitiators zvinotamira pamusoro peiyo inorapa zvinhu, zvichisimbisa hydrophobicity yeUV yekurapa zvinhu.Iyo resin uye monomer mune UV yekurapa fomula zvakare iri hydrophobic muchisikigo, uye iyo yekubata kona inowanzova pakati pe50 ne90 madhigirii.
Styrene sulfonate, polyethylene glycol acrylate, acrylic asidhi nezvimwe zvinhu zvine hydrophilic pachazvo, asi kana zvichishandiswa mu UV kurapa zvinhu, iyo hydrophilicity yezvinhu zvakarapwa haizowedzerwe zvakanyanya, uye kona yekubata kazhinji icharamba yakakura kupfuura madhigirii makumi mashanu.
Hydrophilicity zvinoreva kuti mamorekuru kana mamorekuru akaunganidzwa ari nyore kutora mvura kana kuti anogona kunyungudika nemvura.Pamusoro pezvinhu zvakasimba zvakagadzirwa nemamorekuru akadaro zvinonyoroveswa nyore nyore nemvura.Kushandiswa kwemajasi akawanda kunoda kuti zvinhu zviri pamusoro zviite zvakanaka zvakakwana hydrophilicity, senge firimu, offset printing, special adhesives, biocompatible materials, etc. Mumashandisirwo anoshanda, iyo hydrophilicity inowanzoyerwa nemakona ekusangana kwemvura pane chinhu chakawanikwa. ine angle mita.Zvishandiso zvine makona ekusangana asingasviki madhigirii makumi matatu zvinowanzoonekwa se hydrophilic.
