Umhlahlandlela:kokubili abakhiqizi nabasebenzisi banaka kakhulu okungaphandleukupakishayemikhiqizo, kanye nesidingo semakethe sezinhlobonhlobo zokupakishwa okuphezulu kanye nokupakishwa komuntu siqu kuyakhula.Ekucutshungulweni kwemikhiqizo yangemva kokucindezela, ukuphrinta kwe-UV okufakwe isithwathwa kudonse ukunaka okukhulu ngomphumela wayo oyingqayizivele wokuphrinta wokuphrinta, futhi sekusetshenziswe kabanzi ekupakishweni kwezimboni zokuphrinta ngemibala njengezimonyo nemikhiqizo yokunakekelwa kwezempilo.Lesi sihloko sabelana ngokuqukethwe okufanele kwenqubo yokuphrinta ye-UV eyisithwathwa, ukuze kubhekiswe kubangane:
Ukuphrinta okuyisithwathwa kwe-UV
Ukuphrinta okuyisithwathwa ukuphrinta ungqimba lukayinki oyiqhwa okhanyayo we-UV endaweni engaphansi enokukhanya okufana nesibuko, ephulukiswa i-UV ukuze yakhe indawo eqinile njengengilazi yaphansi, futhi ikakhulukazi isebenzisa indlela yokuphrinta isikrini.Ngenxa yokuthi iphethini ephrintiwe ifana nomphumela wokugqwala kwensimbi, inomuzwa okhethekile onzima.
1 Isimiso
Iphrinte nge-UV yokulingisa yensimbi yesithombe sikayinki eqhwa futhi ingxenye yombhalo ngaphansi kwendawo ekhanyayo-engenalutho, uyinki ohluke ngokucijile ezinhlayiyeni ezincane ekukhanyeni okusabalalisayo, njengendawo ebushelelezi ngemva kokugaya umuzwa wokuboboka esikhundleni sengxenye kayinki, ngenxa yephepha kanye umphumela we-gloss ophezulu ukhiqiza i-specular reflection futhi uzizwe ungaphandle kusenekhadibhodi ecwebezelayo yensimbi yegolide nesiliva.
2 Izinto zokuphrinta
Igolide, amakhadibhodi esiliva kanye nephepha le-vacuum aluminized ngokuvamile lisetshenziswa, futhi indawo engaphezulu iyadingeka ukuthi ibushelelezi, ibe nobushelelezi obukhulu, futhi umphumela wensimbi yesibuko ungakhiqizwa ngemva kokuphrinta.
Ungasebenzisa futhi indlela yokunamathisela umbala ekhadini elimhlophe, okungukuthi, ukusebenzisa izinto zokumboza ukuze uphrinte ukunamathisela kombala wegolide noma wesiliva ekhadini, kodwa ukunamathisela kombala kuyadingeka ukuze kube namandla aphezulu ombala, umbala wokuhlanganisa umfaniswano, izingubo ezingenalutho, futhi ukucwebezela okuhle.Uma kuqhathaniswa nephepha lekhadi legolide nesiliva eliyinhlanganisela, umphumela wephepha lekhadi legolide nesiliva elimboziwe uba mubi kancane.
3 UV frosted inki
Enkambweni yokuphrinta okufakwe iqhwa, umphumela we-frosted uncike ezintweni ezikhethekile ze-UV frosted inki.Uyinki wokuphrinta oyisithwathwa uwuhlobo lukayinki okhanyayo we-UV ongenambala futhi osobala onengxenye eyodwa ye-UV enosayizi wezinhlayiyana ongu-15 ~ 30μm.Imikhiqizo ephrintiwe ngayo inomphumela osobala we-frosted, futhi ifilimu kayinki igcwele, umuzwa wezinhlangothi ezintathu unamandla, ongathuthukisa izinga lomkhiqizo.
Uyinki oyiqhwa we-UV ohlobene noyinki wendabuko osuselwa ku-solvent, unezinzuzo ezihlukile: amaphethini amahle wokuphrinta, umuzwa oqinile wezinhlangothi ezintathu;Ayikho i-solvent, okuqukethwe okuphezulu okuqinile, ukungcoliswa kwemvelo okuncane;Ukwelapha okusheshayo, ukonga amandla, ukusebenza kahle kokukhiqiza okuphezulu;Ifilimu kayinki inokumelana okuhle nokungqubuzana, ukumelana ne-solvent nokumelana nokushisa.
4 Amaphuzu abalulekile enqubo yokuphrinta
01 Iphrinta
Ukuze uqinisekise ukunemba kokubhaliswa, kungcono ukusebenzisa imishini yokuphrinta isikrini esizenzakalelayo ngedivayisi yokwelapha ye-UV.
02 Indawo yokuphrinta
Izinga lokushisa: 25±5℃;Ukuswakama: 45%± 5%.
03 Setha izinga
Umfanekiso wepuleti lokuphrinta nombhalo kufanele uhambisane nemibala yangaphambilini ukuze kuqinisekiswe ukunemba kokuphrinta ngokweqile, futhi iphutha lokuphrinta ngokweqile kufanele libe ngaphansi noma lilingane no-0.25mm.
04 Ukuphrinta umbala ngokulandelana
Ukuphrinta okuneqhwa kungokwezinga eliphezulu lokuphrinta uphawu lokuhweba, okungadingi nje kuphela imibala ecebile, kodwa futhi kudinga ukuba nomsebenzi othile wokulwa nomgunyathi, ngakho ngokuvamile kuthatha indlela yokuhlanganisa ukuphrinta kwemibala eminingi kanye nezindlela ezihlukahlukene zokunyathelisa.
Lapho uhlela ukulandelana kombala wokuphrinta, uyinki oqandisiwe kufanele uhlelwe ekugcineni kombala wokuphrinta.Okufana nokuphrinta isitembu esishisayo esimhlophe, esibomvu, sephethini kanye nomthelela oyisithwathwa, ukulandelana kombala okuvamile ukuphrinta kuqala uyinki omhlophe nobomvu, bese ufaka isitembu esishisayo, bese ekugcineni uphrinte uyinki oyisithwathwa.Ngenxa yokuthi uyinki oyisithwathwa awunambala futhi usobala, uphrintwe phezu kwekhadibhodi legolide nesiliva, ungadlulisa ukucwebezela okungokwemvelo kwensimbi yezinto zokuphrinta, ukuze kuzuzwe umphumela wokuphrinta wokulingisa ukujula kwensimbi.Ngaphezu kwalokho, ukunyathelisa kokugcina uyinki frosted, kodwa futhi ukunyathelisa umbala uyinki odlule.
05 Indlela yokuphila
Ilashwe nge-high pressure mercury lamp.Ukuphila kwesibani ngokuvamile amahora angu-1500 ~ 2000, adinga ukushintshwa njalo.
06 Ingcindezi yokuphrinta
Lapho uphrinta uyinki oyiqhwa, ingcindezi ye-scraper kufanele ibe mkhulu kancane kunokayinki ojwayelekile, futhi ingcindezi kufanele ihambisane.
07 Isivinini sokuphrinta
Usayizi wezinhlayiyana zikayinki oqandisiwe mkhulu.Ukuze wenze uyinki oyisithwathwa ungene ngokugcwele kunemeshi, isivinini sokuphrinta kufanele sibe ngaphansi kunaleso sabanye oyinki.Ngokuvamile esinye isivinini sokuphrinta inki yombala esingu-2500 ± 100 / h;Ijubane lokuphrinta likayinki oqandisiwe ngu-2300±100 amashidi/ihora.
08 Izidingo zesikrini
Ngokuvamile, cishe ama-mesh angama-300 angenisiwe enayiloni engenalutho akhethiwe, futhi ukushuba kwenethiwekhi ye-tension kufana.Enqubweni yokunyathelisa, ukuguqulwa kwepuleti lokunyathelisa kufanele kulawulwe ngokuqinile.
5 Amaphutha nezisombululo ezivamile
01 Ukuthungwa kwensimbi kubi

03 Uyinki womile esikrinini
Imbangela: isikrini sokukhanya kwemvelo esiqondile.Ngenxa yokukhanya kwemvelo kuqukethe ukukhanya okuningi kwe-ultraviolet, kulula ukucupha uyinki ekuphenduleni kokwelapha kwe-photosensitizer.Indawo yephepha noma uyinki oqukethe ukungcola.
Isixazululo: Zama ukugwema ukuchayeka ekukhanyeni kwemvelo;Khetha iphepha elinamandla aphezulu;Indawo yokunyathelisa kufanele igcinwe ihlanzekile.
04 Ukunamathela kodaba lokuphrinta
Imbangela: ungqimba lukayinki endabeni ephrintiwe ayelapheki ngokugcwele.
Isixazululo: thuthukisa amandla eshubhu yesibani somshini oqinile wokukhanya;Yehlisa ijubane lebhande lomshini wokukhanya;Yehlisa ukujiya kongqimba lukayinki ngenkathi uhlangabezana nezimfuneko zokuphrinta.
05 Inguqulo yenduku
Izimbangela: ukuma kwephepha akuvunyelwe, ukuphrinta amazinyo ephepha lesigubhu ukulungiswa okungalungile.
Isixazululo: Linganisa uhlelo lokubeka iphepha, lungisa ukuma kwamazinyo ephepha, ukugwema iphepha elizungeza isigubhu.
06 Ipuleti lokuphrinta liphukile
Izimbangela: ingcindezi yokuphrinta inkulu kakhulu, ukungezwani kwenethiwekhi yokwelula akufani.
Isixazululo: lungisa ukucindezela kwe-scraper ngokulinganayo;Gcina ukushuba kwesimo senethiwekhi yokushuba;Kungcono ukukhetha indwangu ye-mesh engenisiwe.
Imiphetho yombhalo nombhalo inoboya
Imbangela: i-viscosity kayinki inkulu kakhulu.
Isixazululo: engeza i-diluent efanele, lungisa i-viscosity kayinki;Gwema ukudweba uyinki.
