How Fast is UV LED Curing? Ukwelashwa kwe-UV LED kushesha kangakanani? Isikhathi sokuphulukisa ama-inks, ukumboza, nokunamathisela kungathatha ama-milliseconds kuya kumasekhondi ambalwa ngenqubo esheshayo, ephumelelayo yokuphulukisa i-UV LED. Ngokungafani nezibani zendabuko ze-mercury ezisebenzisa ubuchwepheshe be-UV, UV LED izinhlelo zinikeza ukukhanya okugcwele kwe-UV (imvamisa i-365-405 nm), futhi ama-photoinitiators ekwakhiweni aqala ukusebenza ngokushesha.  Ezinye zezici zesikhathi sokwelashwa yilezi: •          Uma kusetshenziswa ukukhanya okwengeziwe, isikhathi esithathiwe siyancipha, futhi isivinini sokuphulukisa sincike kakhulu ekuqineni.  Isibonelo, okukhipha kwe-UV LED kwe-8-16 W / cm² kungaphulukisa ngakho-ke ama-inks amaningi angaphulukisa ngaphansi kwe-1 yesibili. •          Izinto ezingaphezulu ze-opaque noma ezijiyile ziletha isidingo samandla amaningi ukuze i-polymerize ngokuphelele. Thatha isibonelo se-600-800 mJ / cm².  •          Izici ezibonakalayo ezifana nokushuba nohlobo lwe-photoinitiator ye-inki, kanye nokunamathela nokumboza, kunqunywa ijubane lokwelashwa.  •          Ekulungiseleleni kohlelo olufanele, isivinini sokuhambisa singasethwa ku-50-150m ngomzuzu ngezinhlelo ze-LED.  Ukuphulukiswa kwe-UV LED kusheshise izinhlelo zokukhiqizwa kwamadivayisi wezokwelapha, i-elekthronikhi, nokuphrinta ngenxa yokushisa okuncishisiwe nokuthuthukiswa kwejubane nokuqina. Isilinganiso esisheshayo sokuphrinta i-UV LED esinganikeza uma kuqhathaniswa nezindlela ezijwayelekile sifinyelela ezikhathini eziyi-10. Ukuqonda ijubane lokuphulukisa i-UV LED Ukuphulukiswa kwe-UV LED kungumsebenzi we-photochemical osebenzisa ukukhanya kwe-ultraviolet ukudala ukusabela ku-photo-initiator okuholela ekuxhumaniseni i-polymerization yama-inks, ama-adhesives, noma ukumboza. Ngokungafani nezindlela zangaphambilini zokwelapha, ngokuphulukiswa kwe-UV LED, ukwelashwa okugcwele kutholakala ngama-millisecond kuya kumasekhondi, kuye ngokuthi amapharamitha ahlukene.  Speed Influencing ...
