I-Flexo LED UV Curing: Izinzuzo Nokucatshangelwa Kokusetha

Ezweni elisheshayo lokuphrinta ilebula nephakheji, ukuphulukiswa kwe-flexo LED UV kuvele njengezinga elicacile lokusebenza kahle, ikhwalithi, nokusimama. Uma usathembele ezibani ezijwayelekile ze-mercury arc, kungenzeka ukuthi ulwa nokushisa ngokweqile, izikweletu zamandla aphezulu, kanye nesikhathi sokuphumula njalo. Ukushintshela kubuchwepheshe be-LED akuyona nje ukuthuthukisa; Kuyinguquko eyisisekelo enika amandla abaguquli ukuthi baphrinta ngokushesha ebangeni elibanzi lama-substrates ngokuvumelana okuphezulu.

Lo mhlahlandlela uhlola ukuthi kungani imisebenzi ephezulu ye-flexo iguqukela ekwelapheni kwe-LED UV futhi ichaza kahle ukuthi yini odinga ukuyazi ukuze uyisebenzise ngempumelelo.

Kuyini ukuphulukiswa kwe-flexo LED UV futhi kusebenza kanjani?

I-Flexo LED UV yokuphulukisa inqubo ye-photopolymerization esebenzisa ama-Light Emitting Diode (ama-LED) anamandla kakhulu ukomisa ngokushesha ama-inks, ukumboza, kanye nezinamathiselo kuwebhu eguquguqukayo.

Ngokungafani nezibani ze-mercury ezibanzi ezikhipha ukushisa ne-ozone, izinhlelo ze-LED zikhipha amandla e-UV amancane (imvamisa i-385nm noma i-395nm). La mandla ahlosiwe angena ekujuleni kwezingqimba zeyinki, abangela ukusabela okusheshayo ngama-photoinitiators. Umphumela uba ukuphrinta okuphulukisiwe ngokuphelele, okuhlala isikhathi eside okulungele ukuqedwa ngokushesha, ngaphandle kokucindezeleka okushisayo okuhlanekezela izinto ezibucayi.

The Core Mechanism

• Ukusebenza kahle kukagesi: Ama-LED aguqula ugesi ngqo ekukhanyeni kwe-UV ngemfucuza encane.
• Ukuphulukiswa okubandayo: Ukungabi bikho kwemisebe ye-infrared (IR) kugcina iwebhu ipholile.
• Ukuvula / Ukuvala okusheshayo: Ayikho imijikelezo yokushisa noma yokupholisa edingekayo, ukwandisa isikhathi sokucindezela.

Kungani kufanele ushintshele ku-UV ye-LED yokuphrinta kwe-flexo?

Ukushintshela ku-UV ye-LED kunikeza izinzuzo ezintathu ezibucayi zokuncintisana: ukunciphisa okungu-50-80% kwezindleko zamandla, ikhono lokuphrinta kumafilimu amancane azwela ukushisa, kanye nesivinini sokucindezela esiphakeme kakhulu.
