Kusankha Kukula Koyenera kwa UV LED Curing Systems

Makina ambiri ochiritsa a UV LED amakhala ndi nyali za LED zokonzedwa ndikulumikizidwa kuti zipange malo otulutsa. Chifukwa chake, derali likakhala lalikulu, m'pamenenso ma LED a UV amafunikira kuti ma radiation azikhala ofanana.

Komabe, tchipisi ta UV LED nthawi zambiri ndi okwera mtengo ndipo malo okulirapo amatanthauza mtengo wokwera wa nyali za UV LED. Choncho, pa nkhani ya UV inki kuchiritsa mzere m'lifupi ndi yokhazikika, kusankha wololera m'lifupi mwa nyali LED kupeza mtengo kwambiri gwero kuwala, osati akhoza bwino kuchiritsa inki, komanso angapulumutse ndalama. 

Ndiye, timasankha bwanji kukula koyenera kwa machitidwe ochiritsa a UV LED?

Mfundo Zochizira Ink ya UV

Tisanamvetsetse njira yosankhidwa, choyamba tiyenera kumvetsetsa mfundo yochiritsira ya inki ya UV. Kuchiritsa kwa inki ya UV kumaphatikizapo choyambitsa chithunzi cha polymerization mu inki yomwe imayamwa mafoto a utali winawake wautali pansi pa kuyatsa kwa inki.Zida zochizira UV, kuwapangitsa kuti asangalale ndikupanga ma radicals aulere kapena ayoni. Kenako, kudzera mu kutumiza mphamvu pakati pa mamolekyu, polima imakhala yokondwa ndikupanga ma cell transfer complex.

Mwachidule, inki ya UV imayenera kuyamwa mphamvu ya ultraviolet kuti ikwaniritse kuchiritsa. Choncho, zimangofunika kupereka mphamvu zokwanira mkati mwa nthawi yowunikira.

M'lifupi Fomula Yowerengera

M'lifupi mwa gwero la kuwala kwa UV LED zitha kuwerengedwa pogwiritsa ntchito njira iyi:

M'lifupi mwake (L) = QV/W

(Q: Mphamvu Zofunika Pakuchiritsa Inki; V: Kuthamanga kwa Lamba Wotumiza; W: Kuchiritsa Gwero Lamphamvu)

Mwachitsanzo, ngati inki ya UV imafuna 4000mJ kuti ichire, ndipo makina ochiritsira a UV LED ali ndi mphamvu ya 10000mW/cm² ndi lamba wotumizira liwiro la 0.1m/s. Malingana ndi ndondomeko yomwe ili pamwambayi, tikhoza kuwerengera kuti makina ochiritsira a UV LED a 40 mm amafunikira. Kutalika kwa gwero la kuwala nthawi zambiri kumakhala m'lifupi mwa lamba wotumizira, ngati lamba wa conveyor m'lifupi mwake ndi 600mm, zida zochizira inki zomwe zimafunikira mwina ndi 600x40mm malo owala a gwero la kuwala.

Poganizira kukhazikika kwa magwiridwe antchito a zida, malire ena amatha kusiyidwa posankhaKuwongolera kwa UV LEDmachitidwe, mwina mwa kuwonjezera m'lifupi pang'ono kapena posankha makina apamwamba kwambiri.
