Paunenge uchishandisa UV flatbed printer kudhinda zvimwe zvinhu, nekuda kwekuwomeswa kweiyo UV inki, dzimwe nguva zvinotungamira kune dambudziko rekuderera kunamatira kweiyo UV inki kune substrate.Ichi chinyorwa ndechekudzidza maitiro ekuvandudza kunamatira kweiyo UV inki kune substrate.
corona kurapwa
Iye munyori akaona kuti corona kurapwa inzira inogona kunyatso kuvandudza kunamatira kweUV inki!Iwo akanaka uye asina kunaka maelectrodes eiyo corona mudziyo akaiswa pasi pasi pasi uye Yuden mweya nozzle zvichiteerana.Maerekitironi emahara ane simba rakawanda anokwidziridzwa kuenda kune yakanaka electrode, inogona kushandura polarity yechinhu chisina kunyura uye kuwedzera kushata kwepamusoro, kusimudzira kugona kusanganisa neingi, kuwana iyo chaiyo UV inki adhesion, uye kuvandudza kunamatira. kutsanya kweinki layer..
Corona-yakarapwa zvinhu zvine kushomeka kwepamusoro-soro kugadzikana, uye iyo corona mhedzisiro inopera zvishoma nezvishoma nekufamba kwenguva.Kunyanya munzvimbo ine hunyoro hwepamusoro, iyo corona mhedzisiro inopera simba nekukurumidza.Kana corona yakarapwa substrates ikashandiswa, kushandira pamwe nemupi kunofanirwa kuitwa kuti ive nechokwadi chekutsva kweiyo substrates.Zvakajairika corona kurapwa zvinhu zvinosanganisira PE, PP, naironi, PVC, PET, nezvimwe.
UV ink adhesion kukurudzira (AdhesionPromoters)
Muzviitiko zvakawanda, kuchenesa substrate nedoro kunovandudza kunamatira kweiyo UV inki kune substrate.Kana kunamatira kweiyo substrate kune UV inki kwakashata kwazvo, kana chigadzirwa chine zvakakwirira zvinodiwa pakunamira kweiyo UV inki, unogona kufunga kushandisa primer/UV ingi adhesion kusimudzira inosimudzira kunamatira kweiyo UV inki.
Mushure mekunge iyo primer yaiswa pane isiri-inonyura substrate, kunamatira kweiyo UV inki inogona kuvandudzwa kuti iwane yakanakira adhesion athari.Yakasiyana nekurapa kwekorona, zvinhu zvemakemikari primer hazvina mamorekuru asina-polar ane mafuta, ayo anogona kunyatsobvisa dambudziko rekusagadzikana kwecorona mhedzisiro inokonzerwa nekutama kwemamorekuru akadaro.Nekudaro, huwandu hwekushandiswa kweiyo primer inosarudza, uye inoshanda zvakanyanya kune girazi, ceramic, simbi, acrylic, PET uye mamwe ma substrates.
UV inki yekurapa degree
Kazhinji, isu tinokwanisa kuona kusabatana kwakashata kwemaingi eUV pane asingatore ma substrates mumamiriro ezvinhu apo ingi dzeUV hadzina kupora zvizere.Kuti uvandudze dhigirii rekurapa re UV inki, unogona kutanga kubva pane zvinotevera zvinhu:
1) Wedzera simba remwenje weUV wekurapa.
2) Deredza kukurumidza kudhinda.
3) Wedzera nguva yekurapa.
4) Tarisa uone kana mwenje weUV uye zvishandiso zvawo zviri kushanda nemazvo.
5) Deredza kukora kweiki layer.
Dzimwe nzira
Kupisa: Muindasitiri yekudhinda skrini, zvinokurudzirwa kupisa iyo substrate isati yapora UV isati yadhinda pane yakaoma-ku-kunamatira substrates.Iko kunamatira kweingi dzeUV kune substrates kunogona kukwidziridzwa mushure mekupisa nepedyo-infrared kana kure-infrared mwenje kwemasekonzi gumi nemashanu-90.
Varnish: Kana iyo UV inki ichiri nematambudziko ekunamatira kune substrate mushure mekushandisa mazano ari pamusoro apa, varnish inodzivirira inogona kuiswa pamusoro pekudhindwa.
