Umhleli we umshini wokunyathelisa isikrini umenzi uzokuchazela amakhono okugcina umthombo wokukhanya we-UV kanye nezinsiza ekuphrinteni kwe-UV yomshini wokuphrinta wesikrini okokusebenza okusekelayo.
Imishini yokuphrinta yomshini wokuphrinta wesikrini Umshini wokuphulukisa we-UV, ukusetshenziswa kukayinki we-UV noma ivarnish ye-UV kungase kubangele ukuthi ingubo yokunyathelisa yerola ye-inki noma ipuleti lomunwe wesihlahla livuvuke. Ukuvuvukala okunamandla kuzodala ukuxebuka noma ukucweba komhlaba. Kubaluleke kakhulu ukusebenzisa amapuleti enjoloba kanye nomunwe wesihlahla oqokiwe.
Abahlinzeki abaningi be-ink ye-UV bazoncoma ububanzi bokusetshenziswa, njenge-blanket nitrification noma izinto zokwelashwa ze-nitrification zingahlanganiswa noyinki we-UV onamafutha kanye nevanishi; kuyilapho izinto zenjoloba yemvelo kanye ne-polyethylene zizovuvukala, azifaneleki uyinki ye-UV Kanye ne-varnish; Impahla yerabha ye-EPDM ifaneleka ngokukhethekile uyinki ye-UV nevanishi, kodwa ayilungele uyinki ovamile. Irola yeyinki yomshini wokuphrinta isikrini nayo isekelwe kulesi simiso. Akuvamile ukuthi kwenzeke ukushintshela kuyinki we-UV kanye noyinki onamafutha ojwayelekile. Uma idinga ukushintshwa, kufanele ihlanzwe ukuze kukhishwe wonke amakhemikhali asele.

Ngokuvamile, uhlobo lomshini wokunyathelisa kufanele lucatshangelwe lapho kufakwa amalambu e-UV. Amayinki e-BASF UV namavanisha asebenzisa amalambu e-pressure mercury noma ama-microwave H alungele ukusetshenziswa ezimbonini. Uma owokuqala ungumbala owodwa, kufanele kusetshenziswe izigaxa ezimbili ze-mercury ezicindezelayo ezimaphakathi ezimbili ezingu-120w/cm. Ngokuvamile, ubunzima bokomisa uyinki ye-UV enemibala emine i-magenta, i-yellow-cyan, kanye nomnyama ngokulandelana. Ngakho-ke, ukuhleleka kokuphrinta kombala we-UV kufanele kube mnyama, cyan, ophuzi, kanye ne-magenta.
Kunzima kakhulu ukuxuba imibala ethile. Isibonelo, okuluhlaza okwenziwe ngophuzi kanye ne-cyan. Ngaphezu kwalokho, kunzima ukuhlanganisa imibala ekhanyayo ngoba ikhombisa wonke ukukhanya kwe-UV emuva. Inkinga efanayo ikhona emibaleni efanayo eyinsimbi, esagolide, nesiliva.
Isibani se-UV mercury sinesikhathi esithile sokuphila, ishubhu yesibani endala kakhulu ayikwazi ukomisa uyinki noma ukuvenisha kwe-UV. Iningi lemiyalo yesibani se-UV ikhombisa ukuthi isibani se-UV kufanele sishintshwe ngemuva kokusetshenziswa kwamahora ayi-1,000. Ekukhiqizweni kwangempela, uma unomuzwa wokuthi into ephrintiwe ayikwazi ukomiswa ngesivinini esivamile sokuphrinta, kufanele ucabangele ukufaka isibani se-UV esikhundleni.
Uma isibonisi singafakiwe, cishe u-80% wesibani se-UV ngeke ukwazi ukusebenza endabeni ephrintiwe ngenxa yokusabalalisa, ngakho-ke isibani se-UV kufanele sifakwe nomthunzi wesibani ukuze sibonise futhi sigxile ekuqondeni kwendaba ephrintiwe. . Ozakwethu, isibonisi kufanele sihlanzwe futhi sinakekelwe noma nini. Uma uthuli oluthile lwephepha noma uthuli oluvela kumpushana wokufafaza lunamathela kusibonisi, luzothinta umphumela wokubonisa wesibani se-UV; uma isibani se-UV singasetshenziswa isikhathi eside, ikhava yesibani se-UV kufanele futhi ivalwe ukuvimbela uthuli ukuthi lungangeni.
Okungenhla amakhono okunakekela umthombo wokukhanya kwe-UV kanye nezinsiza ekuphrinteni kwe-UV okumataniswe nomshini wokuphrinta wesikrini.
