Iningi le-UV LED yokuphulukisa uhlelo luqukethe amalambu e-LED ahlelwe futhi axhunywe ukwenza indawo ephumayo. Ngakho-ke, lapho indawo inkulu, kudingeka ama-LED amaningi e-UV ukuze kugcinwe ukuqina kwemisebe efanayo.
Kodwa-ke, ama-chips e-UV LED ngokuvamile abiza kakhulu futhi indawo enkulu isho inani eliphakeme lamalambu e-UV LED. Ngakho-ke, endabeni yobubanzi bomugqa wokwelapha oyinki we-UV bumisiwe, ukukhethwa okunengqondo kobubanzi besibani se-LED ukuze kutholwe umthombo wokukhanya ongabizi kakhulu, akugcini nje ngokuqeda kangcono ukuphulukiswa kweyinki, kodwa futhi kungasindisa izindleko.
Ngakho-ke, sikhetha kanjani ububanzi obufanele bezinhlelo zokuphulukisa ze-UV LED?
Izimiso Zokuphulukisa Uyinki we-UV
Ngaphambi kokuqonda indlela yokukhetha, okokuqala sidinga ukuqonda isimiso sokuphulukisa sikayinki we-UV. Ukwelashwa kwe-ink ye-UV kubandakanya isiqalisi se-photo-polymerization kumaphothoni amunca uyinki wobude obuthile begagasi ngaphansi kokukhanyaImishini yokwelapha ye-UV, okubenza bajabule futhi benze ama-radicals mahhala noma ama-ion.Bese, ngokudluliswa kwamandla phakathi kwama-molecule, i-polymer iyajabula futhi ikhiqize izakhiwo zokudlulisa ukushaja.
Ngamagama alula, uyinki we-UV udinga ukumunca amandla e-ultraviolet ukuze uthole ukwelashwa. Ngakho-ke, kudinga kuphela ukunikeza amandla anele phakathi nesikhathi sokushiswa kwemisebe.
Ububanzi Ukubala Formula
Ububanzi bomthombo wokukhanya we-UV LED bungabalwa kusetshenziswa ifomula elandelayo:
Ububanzi bomthombo wokukhanya (L) = QV/W
(Uq: Amandla Adingekayo Ukuze Ukwelapha Uyinki; V: Ijubane Lebhande Lokuthutha; W: Amandla Omthombo Wokukhanya Wokwelapha)
Isibonelo, uma uyinki ye-UV idinga u-4000mJ ukuze welashwe, futhi umshini wokwelapha we-UV LED unamandla angu-10000mW/cm² kanye nesivinini sebhande lokudlulisa elingu-0.1m/s. Ngokusekelwe kufomula engenhla, ingabalwa ukuthi umshini wokwelapha we-UV LED ongu-40 mm ububanzi uyadingeka.Ubude bomthombo wokukhanya ngokuvamile buwububanzi bebhande lokudlulisa. Ubude bomthombo wokukhanya ngokuvamile buwububanzi bebhande lokuthutha, uma ububanzi bebhande lokudlulisela elingu-600mm, okokusebenza okuyinki okuphulukisayo okudingekayo cishe indawo engu-600x40mm yokukhanyisa indawo yomthombo wokukhanya.
Uma kucatshangelwa ukuzinza kokusebenza kwemishini, umkhawulo othile ungashiywa lapho kukhethwaUkwelashwa kwe-UV LEDizinhlelo, noma ngokukhuphula kancane ububanzi noma ngokukhetha umshini onamandla aphezulu.
