UV kusindikiza ndi njira yapadera yakusindikiza kwa digitokugwiritsa ntchito kuwala kwa ultraviolet (UV) kuti ziume kapena kuchiritsa inki, zomatira kapena zokutira pafupi ndi pepala, kapena aluminiyamu, foam board kapena acrylic - makamaka bola zikwanira chosindikizira, njirayo itha kugwiritsidwa ntchito sindikizani pafupifupi chilichonse.
Njira yochiritsira UV - njira yowumitsa zithunzi - idayambitsidwa ngati njira yowumitsa mwachangu misomali ya gel yomwe imagwiritsidwa ntchito popanga manicure, koma posachedwapa idalandiridwa ndi makampani osindikizira komwe amagwiritsidwa ntchito kusindikiza pa chilichonse kuchokera pazikwangwani ndi timabuku. ku mabotolo a mowa. Njirayi ndi yofanana ndi kusindikiza kwachikhalidwe, kusiyana kokha ndi inki zomwe zimagwiritsidwa ntchito ndi kuyanika - ndi zinthu zapamwamba zomwe zimapangidwa.
Pazosindikiza zachikhalidwe, inki zosungunulira zimagwiritsidwa ntchito; izi zimatha kusanduka nthunzi ndikutulutsa ma volatile organic compounds (VOCs) omwe ndi owopsa ku chilengedwe. Njirayi imapanganso - ndikugwiritsanso ntchito - kutentha ndi fungo lotsatizana. Kuphatikiza apo, pamafunika ma ufa owonjezera opopera kuti athandizire pakuchotsa inki ndikuyanika, zomwe zingatenge masiku angapo. Ma inki amalowetsedwa m'malo osindikizira, kotero mitundu imatha kuwoneka ngati yatha ndipo yatha. Njira yosindikizira imangokhala pamapepala ndi makadi, kotero singagwiritsidwe ntchito pazinthu monga pulasitiki, galasi, zitsulo, zojambulazo kapena acrylic monga kusindikiza kwa UV.
Mu kusindikiza kwa UV, mercury / quartz kapena magetsi a LED amagwiritsidwa ntchito pochiritsa m'malo mwa kutentha; kuwala kopangidwa mwapadera kwamphamvu kwambiri kwa UV kumatsatira mosamalitsa ngati inki yapadera imagawidwa pamalo osindikizira, kuumitsa ikangoyikidwa. Chifukwa inki imasintha kuchoka ku cholimba kapena phala kupita kumadzi nthawi yomweyo, palibe mwayi woti asunthe ndipo palibe ma VOC, utsi wapoizoni kapena ozoni omwe amatulutsidwa, zomwe zimapangitsa ukadaulo kukhala wogwirizana ndi chilengedwe ndi pafupifupi zero carbon footprint.
Inki, zomatira kapena zokutira zimakhala ndi chisakanizo cha ma monomers amadzimadzi, oligomers - ma polima okhala ndi magawo ochepa obwereza - ndi ma photoinitiators. Panthawi yochiritsa, kuwala kwamphamvu kwambiri mu gawo la ultraviolet la sipekitiramu, yokhala ndi kutalika kwapakati pa 200 ndi 400 nm, imatengedwa ndi photoinitiator yomwe imakumana ndi mankhwala - kulumikizana ndi mankhwala - ndikupangitsa inki, zokutira kapena zomatira. kuumitsa nthawi yomweyo.
Ndizosavuta kuwona chifukwa chake kusindikiza kwa UV kwadutsa njira zachikhalidwe zamadzi ndi zosungunulira zowumitsa zosungunulira komanso chifukwa chake zikuyembekezeka kupitiliza kutchuka. Sikuti njirayo imafulumizitsa kupanga - kutanthauza kuti zambiri zimachitika mu nthawi yochepa - mitengo yokana imachepetsedwa pamene ubwino uli wapamwamba. Madontho onyowa a inki amachotsedwa, kotero palibe kupukuta kapena kupukuta, ndipo monga kuyanika kuli pafupi nthawi yomweyo, palibe kuphulika kotero kuti palibe kutaya kwa makulidwe kapena voliyumu. Zambiri ndizotheka, ndipo mitundu imakhala yakuthwa komanso yowoneka bwino chifukwa palibe mayamwidwe pa makina osindikizira: kusankha makina osindikizira a UV kuposa njira zachikhalidwe zosindikizira kungakhale kusiyana pakati pa kupanga chinthu chapamwamba, ndi china chake chomwe chimamveka chocheperako.
Ma inki alinso ndi mawonekedwe owoneka bwino, kumaliza bwino kwa gloss, kukanda bwino, mankhwala, zosungunulira ndi kuuma kulimba, kukhazikika bwino komanso kumaliza kumapindulanso chifukwa champhamvu. Zimakhalanso zolimba komanso zosagwirizana ndi nyengo, ndipo zimapereka kukana kowonjezereka kwa kuzimiririka kuzipangitsa kukhala zabwino kwa zikwangwani zakunja. Njirayi imakhalanso yotsika mtengo - zinthu zambiri zimatha kusindikizidwa mu nthawi yochepa, pamtundu wabwino komanso osakanidwa pang'ono. Kuperewera kwa ma VOCs komwe kumatulutsa pafupifupi kumatanthauza kuti chilengedwe sichiwonongeka ndipo mchitidwewu ndi wokhazikika.
