Ukuphrinta uyinki we-UV ngokuvamile kusebenzisa indlela yokomisa kwe-UV ngokushesha, ukuze uyinki ukwazi ukunamathela ngokushesha ebusweni befilimu ezinamathelayo. Kodwa-ke, ngesikhathi sokunyathelisa, inkinga yokunamathela okungalungile kweyinki ye-UV ebusweni bezinto zokuzinamathisela ifilimu ngokuvamile ivela.
Kuyini ukunamathela okubi kweyinki ye-UV?
Amatheminali ahlukene anezindlela ezihlukene zokuhlola ukunamathela okubi kweyinki ye-UV. Kodwa-ke, embonini yelebula ezinamathelayo, amakhasimende amaningi azosebenzisa itheyiphu engu-3M 810 noma engu-3M 610 ukuhlola ukunamathela kweyinki.
Imibandela yokuhlola: Ukuqina kukayinki kuhlolwa ngokwenani likayinki obhajwe ngemva kokuba itheyiphu yokunamathela inamathele endaweni yelebula bese isuswa.
Ileveli 1: awekho uyinki
Izinga 2: Uyinki omncane uyawa (<10%)
Ileveli 3: ukuchithwa kukayinki omaphakathi (10%~30%)
Ileveli 4: ukuchithwa kukayinki obucayi (30%~60%)
Izinga lesi-5: cishe wonke uyinki uyawa (>60%)
umbuzo 1:
Ekukhiqizeni, sivame ukuhlangana nenkinga yokuthi lapho ezinye izinto zinyatheliswa ngokujwayelekile, ukunamathela kweyinki KULUNGILE, kodwa ngemva kokuba isivinini sokunyathelisa sithuthukisiwe, ukunamathela kweyinki kuba kubi kakhulu.

Njengoba i-photoinitiator kuyiyinki ye-UV idonsa ukukhanya kwe-UV ukuze ikhiqize ama-radicals mahhala, izonqamula isixhumanisi ne-monomer prepolymer engxenyeni ye-inki ukuze yakhe isakhiwo senethiwekhi, okuyinqubo yesikhashana ukusuka oketshezini kuya kokuqinile. Nokho, ekunyatheliseni kwangempela, nakuba ingaphezulu likayinki loma ngaso leso sikhathi, kwakunzima ngokukhanya kwe-ultraviolet ukuba kungene ungqimba olungaphezulu lukayinki oluqinile ukuze lufinyelele ungqimba olungezansi, okuholela ekuphenduleni okungaphelele kwe-photochemical kayinki ongaphansi.
Isiphakamiso:Ngoyinki ojulile nokuphrinta okukhanyayo, uyinki wamandla ombala ophezulu ungasetshenziswa ukunciphisa ukushuba kwesendlalelo sikayinki, okungagcini nje ngokuqinisekisa ukoma kwe-inki yongqimba olulodwa, kodwa futhi kuthuthukise ngempumelelo ukusebenza kahle kokukhiqiza.

Isibani se-UV mercury ngokuvamile sisetshenziswa amahora angaba ngu-1000, futhi singakhanyiswa ngemva kokuba isibani se-UV sisetshenziswe amahora angaphezu kuka-1000, kodwa uyinki we-UV awukwazi ukoma ngokuphelele. Eqinisweni, uma isibani se-UV sesifinyelele impilo yaso yesevisi, ijika laso le-spectral selishintshile. Ukukhanya kwe-ultraviolet okukhishwayo akuhlangabezani nezidingo ze-inki eyomile, futhi amandla e-infrared anyukile, okuholela ekulimaleni kwezinto ezibonakalayo kanye nokukhishwa kwe-inki ngenxa yokushisa okuphezulu.
Isiphakamiso:Isikhathi sokusebenzisa isibani se-UV kufanele sirekhodwe ngendlela efanele futhi sishintshwe ngesikhathi. Ngesikhathi sokukhiqiza okuvamile, kuyadingeka futhi ukuthi uhlole njalo ukuhlanzeka kwesibani se-UV futhi uhlanze isibonisi. Ngokuvamile, i-1/3 kuphela yamandla esibani se-UV ekhanya ngokuqondile endaweni ebonakalayo, futhi u-2/3 wamandla uboniswa isibonisi.

Isikhathi sokuxhumana esifushane phakathi kwe-inki ne-substrate siholela ekuxhumekeni kweleveli yamangqamuzana okwanele phakathi kwezinhlayiya, okuthinta ukunamathela
Izinhlayiya zikayinki ne-substrate ziyahlakazeka futhi zixhumane ukuze zakhe uxhumano lweleveli yamangqamuzana. Ngokwandisa isikhathi sokuthintana phakathi kweyinki ne-substrate ngaphambi kokoma, umphumela wokuxhuma phakathi kwama-molecule ungaba obaluleke kakhulu, ngaleyo ndlela ukhulise ukunamathela kweyinki.
Ukusikisela: yehlisa isivinini sokuphrinta, yenza ukuthi uyinki uxhumane ngokugcwele ne-substrate, futhi uthuthukise ukunamathela kweyinki.
Isizathu 2:
isikhathi esinganele sokuchayeka kokukhanya kwe-UV, okuholela ekutheni uyinki ungomi ngokuphelele, uthinte ukunamathela
Ukwenyuka kwesivinini sokuphrinta kuzophinde kufinyeze isikhathi sokushiswa kwemisebe yokukhanya kwe-UV, okuzonciphisa amandla akhanya kuyinki, ngaleyo ndlela kuthinte isimo sokoma sikayinki, okuholela ekubambeni kabi kokunamathela ngenxa yokomiswa okungaphelele.
Isiphakamiso:Yehlisa isivinini sokuphrinta, yeka uyinki wome ngokugcwele ngaphansi kwesibani se-UV, futhi uthuthukise ukunamathela.
