Ukukhetha Ububanzi obufanelekileyo kwiiNkqubo zokuNyanga i-UV LED

Ukukhetha Ububanzi obufanelekileyo kwiiNkqubo zokuNyanga i-UV LED

Uninzi lwenkqubo yokunyanga ye-UV ye-LED inezibane ze-LED ezicwangcisiweyo kwaye ziqhagamshelwe ukwenza indawo yokukhupha. Ke ngoko, okukhona ummandla umkhulu, kokukhona kufuneka ii-LED ze-UV ezingakumbi ukuze zigcine ubushushu obufanayo bemitha.

Nangona kunjalo, iitshiphusi ze-UV ze-LED zihlala zibiza kakhulu kwaye indawo enkulu ithetha ixabiso eliphezulu kwizibane ze-UV ze-UV. Ke ngoko, kwimeko yobubanzi be-inki yokunyanga ye-UV buzinzile, ukhetho olufanelekileyo lobubanzi besibane se-LED ukufumana umthombo wokukhanya ongabizi kakhulu, ayisinokugqiba ngcono ukunyanga inki, kodwa kunokonga iindleko. 

Ke, sikhetha njani ububanzi obufanelekileyo kwiinkqubo zokunyanga ze-UV LED?

Imigaqo yokunyanga i-Ink ye-UV

Ngaphambi kokuba siqonde indlela yokukhetha, kufuneka siqale siqonde umgaqo wokunyanga we-inki ye-UV. Ukunyangwa kwe-inki ye-UV kubandakanya umqalisi we-photo-polymerization kwi-inki efunxa iifoto zobude obuthile phantsi kokukhanyaIzixhobo zokunyanga ze-UV, okubangela ukuba bavuyiswe kwaye benze i-radicals yamahhala okanye i-ion.Emva koko, ngokugqithiswa kwamandla phakathi kwama-molecule, i-polymer iba nemihlali kwaye ivelise ii-complexes zokudluliselwa kwentlawulo.

Ngamagama alula, i-inki ye-UV idinga ukufunxa amandla e-ultraviolet ukufezekisa ukunyanga. Ngoko ke, kufuna kuphela ukubonelela ngamandla aneleyo ngexesha lokutshisa.

Ububanzi bokubala ifomula

Ububanzi bomthombo wokukhanya kwe-UV LED bunokubalwa kusetyenziswa le fomula ilandelayo:

 

Ububanzi bomthombo wokukhanya (L) = QV/W

(Q: Amandla afunekayo kwi-Ink Curing; V: Isantya sebhanti leConveyor; W: Ukunyanga uMthombo wokuKhanya amandla)

 

Umzekelo, ukuba i-inki ye-UV ifuna i-4000mJ yokunyanga, kwaye umatshini wokunyanga we-UV LED unamandla ayi-10000mW/cm² kunye nebhanti lokuhambisa isantya se-0.1m/s. Ngokusekelwe kwifomula engentla, ingabalwa ukuba i-40 mm ububanzi be-UV LED umatshini wokunyanga iyadingeka.Ubude bomthombo wokukhanya ngokuqhelekileyo ububanzi bebhanti yokuhambisa. Ubude bomthombo wokukhanya ngokuqhelekileyo bububanzi bebhanti lokuhambisa, ukuba ibhanti lokuhambisa ububanzi be-600mm, isixhobo sokunyanga i-inki esifunekayo mhlawumbi yi-600x40mm indawo yokukhanya yomthombo wokukhanya.

Ukuqwalasela ukuzinza kokusebenza kwezixhobo, umda othile unokushiywa xa ukhethaUkunyanga kwe-UV LEDiinkqubo, mhlawumbi ngokunyusa kancinane ububanzi okanye ngokukhetha umatshini wokuxina okuphezulu.
