Gabaɗaya, bugu na UV ya ƙunshi nau'ikan fasahohi masu zuwa:
1. Kayan Aikin Tushen Hasken UV
Wannan ya haɗa da fitilu, na'urorin haskakawa, tsarin sarrafa makamashi, da tsarin sarrafa zafin jiki (sanyaya).
(1) Fitilun
Fitilun UV da aka fi amfani da su sune fitilun tururin mercury, waɗanda ke ɗauke da mercury a cikin bututun. A wasu lokuta, ana ƙara wasu ƙarfe kamar gallium don daidaita fitowar spectral.
Ana kuma amfani da fitilun ƙarfe da na quartz sosai, kuma har yanzu ana shigo da su daga ƙasashen waje.
Tsarin tsawon raƙuman ruwa da fitilun UV ke fitarwa dole ne ya faɗi tsakanin kimanin nm 200-400 domin ya yi tasiri wajen warkewa.
(2) Masu nuna haske
Babban aikin mai haskakawa shine mayar da hasken UV zuwa ga substrate don ƙara ingancin warkarwa (UV Tech Publications, 1991). Wani muhimmin aiki kuma shine taimakawa wajen kiyaye yanayin zafin aiki na fitila mai dacewa.
Ana yin reflectors yawanci da aluminum, kuma reflectance gabaɗaya ana buƙatar ya kai kusan kashi 90%.
Akwai ƙirar haske guda biyu na asali: mai da hankali (elliptical) da kuma wanda ba a mai da hankali ba (parabolic), tare da ƙarin bambance-bambancen da masana'antun suka haɓaka.
(3) Tsarin Kula da Makamashi
Waɗannan tsarin suna tabbatar da cewa fitowar UV ta kasance mai karko, tana kiyaye inganci da daidaito na tsaftacewa yayin da take daidaitawa da saurin bugawa daban-daban. Wasu tsarin ana sarrafa su ta hanyar lantarki, yayin da wasu kuma suna amfani da sarrafa kwamfuta ta microcomputer.
2. Tsarin Sanyaya
Saboda fitilun UV ba wai kawai suna fitar da hasken UV ba, har ma da zafin infrared (IR), kayan aikin suna aiki a yanayin zafi mai yawa (misali, zafin saman fitilun da aka yi da quartz na iya kaiwa digiri ɗari da yawa na Celsius).
Zafi mai yawa na iya rage tsawon rayuwar kayan aiki kuma yana iya haifar da faɗaɗa substrate ko nakasa, wanda ke haifar da kurakuran rajista yayin bugawa. Saboda haka, tsarin sanyaya yana da matuƙar muhimmanci.
3. Tsarin Samar da Tawada
Idan aka kwatanta da tawada ta gargajiya, tawada ta UV tana da ɗanko mai yawa da kuma gogayya mai yawa, kuma suna iya haifar da lalacewa ga kayan injin kamar barguna da na'urori masu juyawa.
Saboda haka, yayin bugawa, ya kamata a ci gaba da tayar da tawada a cikin maɓuɓɓugar ruwa, kuma ya kamata a yi amfani da abin birgima da barguna a cikin tsarin tawada don ƙirƙirar kayan da aka tsara musamman don buga UV.
Domin kiyaye daidaiton tawada da kuma hana canje-canjen da suka shafi zafin jiki, tsarin sarrafa zafin jiki na birgima suma suna da mahimmanci.
4. Tsarin Watsar Zafi da Shaye-shaye
Waɗannan tsarin suna cire zafi mai yawa da kuma ozone da aka samar yayin polymerization na tawada da kuma warkarwa.
Yawanci suna ƙunshe da injin fitar da hayaki da tsarin bututun iska.
[Samar da iskar Ozone galibi tana da alaƙa da raƙuman UV a ƙasa da ~240 nm; yawancin tsarin zamani suna rage iskar Ozone ta hanyar tacewa ko tushen LED.]
5. Tawada Mai Bugawa
Ingancin tawada shine mafi mahimmancin abin da ke shafar sakamakon buga UV. Baya ga tasirin sake haifuwar launi da gamut, iyawar buga tawada kai tsaye yana ƙayyade mannewa, ƙarfi, da juriyar gogewa na bugu na ƙarshe.
Halayen masu ƙirƙirar photoinitiators da monomers suna da mahimmanci ga aiki.
Domin tabbatar da cewa an manne sosai, lokacin da tawada mai launin UV ta haɗu da substrate, dole ne a sami matsin lamba daga saman substrate (dynes/cm) fiye da na tawada (Schilstra, 1997). Saboda haka, sarrafa matsin lamba daga saman tawada da substrate babbar fasaha ce a cikin buga UV.
6. Na'urorin auna makamashin UV
Saboda abubuwa kamar tsufan fitila, canjin wutar lantarki, da canje-canjen saurin bugawa na iya shafar warkarwa, yana da mahimmanci a sa ido da kuma kiyaye ingantaccen fitowar makamashin UV. Don haka, fasahar auna makamashin UV tana taka muhimmiyar rawa a bugun UV.
