Doorashada Balladhka Ku Haboon ee Nidaamyada Daaweynta UV LED

Inta badan habka daaweynta UV LED wuxuu ka kooban yahay nalal LED ah oo habaysan oo ku xiran si ay u sameeyaan dusha sare ee qiiqaya. Sidaa darteed, aagga weyn, inta badan LED-yada UV ayaa looga baahan yahay si loo ilaaliyo xoogga shucaaca isku midka ah.

Si kastaba ha ahaatee, chips UV LED guud ahaan waa ka qaalisan yihiin oo aagga weyn macnaheedu waa qiimo sare ee nalalka UV LED. Sidaa darteed, in the case of UV khad daawaynta width line waa go'an, xulashada macquul ah ee width ee nalka LED si aad u hesho ilo iftiin kharash-ool ah oo dheeraad ah, ma aha oo kaliya si fiican u dhamaystiri kartaa daaweynta khad, laakiin sidoo kale badbaadin kara kharashyada. 

Marka, sidee baan u dooran karnaa ballaca ku habboon nidaamyada daaweynta UV LED?

Mabaadi'da Daweynta UV

Kahor intaanan fahmin habka xulashada, waxaan marka hore u baahanahay inaan fahanno mabda'a daweynta ee khad UV. Dawaynta khad UV waxay ku lug leedahay bilawga sawir-polymerization ee khad soo nuugaya sawir-qaadayaasha mawjadaha gaarka ah ee hoos yimaada shucaacaQalabka daaweynta UV, taasoo keenaysa inay ku faraxsan yihiin oo ay sameeyaan xagjirnimo lacag la'aan ah ama ions. Kadib, iyada oo loo marayo wareejinta tamarta ee u dhaxaysa molecules, polymer-ku wuu faraxsan yahay oo wuxuu abuuraa dhismooyin wareejin ah.

Si fudud, khad UV wuxuu u baahan yahay inuu nuugo tamarta ultraviolet si loo gaaro daaweynta. Sidaa darteed, waxay u baahan tahay oo kaliya bixinta tamar ku filan wakhtiga shucaaca gudahooda.

Foomamka Xisaabinta Ballaca

Ballaca isha iftiinka UV LED waxaa lagu xisaabin karaa qaacidooyinka soo socda:

Ballaca isha iftiinka (L) = QV/W

(Q: Tamarta Looga Baahan Yahay Khad Daawaynta; V: Xawaaraha suunka wareejinta; W: Awoodda Isha Iftiinka Curing)

Tusaale ahaan, haddii khad UV u baahan yahay 4000mJ si loo daweeyo, iyo UV LED daawaynta mishiinka uu leeyahay awood 10000mW/cm² iyo suunka qaada xawaaraha 0.1m/s. Iyada oo ku saleysan caanaha kor ku xusan, waxaa la xisaabin karaa in loo baahan yahay 40 mm ballaaran oo ah mashiinka daaweynta UV LED. Dhererka iftiinka iftiinka guud ahaan waa ballaca suunka gudbinta. Dhererka isha iftiinka guud ahaan waa balladhka suunka wax qaada, haddii ballaca suunka gudbinta uu yahay 600mm, qalabka lagu daweeyo khad ee loo baahan yahay waxay u badan tahay 600x40mm aagga iftiinka iftiinka.

Iyadoo la tixgelinayo xasiloonida hawlgalka qalabka, meel gaar ah ayaa laga tagi karaa marka la dooranayoDaawaynta UV LEDnidaamyada, ama adoo xoogaa kordhinaya ballaca ama adoo dooranaya mashiinka xoogga sare.
