Ubwino wa UV/LED Kuchiritsa Zomatira

Kodi chifukwa chachikulu chogwiritsira ntchito zomatira zochiritsira za LED ndi chiyani pa zomatira zochiritsira za UV?

Zomatira zochiritsira za LED nthawi zambiri zimachiza mu masekondi 30-45 pansi pa gwero la kuwala kwa 405 nanometer (nm) wavelength. Zomatira zachikhalidwe zochizira kuwala, mosiyana, zimachiritsa pansi pa kuwala kwa ultraviolet (UV) ndi mafunde apakati pa 320 ndi 380 nm. Kwa akatswiri opanga mapangidwe, kuthekera kochiritsa zomatira pansi pa kuwala kowonekera kumatsegula njira zingapo zomangira, zotsekera ndi kusindikiza zomwe poyamba sizinali zoyenera kupangira mankhwala ochizira, chifukwa m'mapulogalamu ambiri, magawowo samatha kufalikira mu UV wavelength koma amalola kuti ziwonekere. kufala kwa kuwala

Kodi ndi zinthu ziti zomwe zingakhudze nthawi ya machiritso?

Nthawi zambiri, kuwala kwa nyali ya LED kuyenera kukhala pakati pa 1 ndi 4 Watts/cm2. Kuganiziranso kwina ndi mtunda wochokera ku nyali kupita kumalo omatira, mwachitsanzo, kutali ndi nyali kuchokera ku zomatira, nthawi yayitali yochiritsa. Zina zomwe ziyenera kuganiziridwa ndi makulidwe a zomatira, wosanjikiza wocheperako amachiritsa mwachangu kuposa wosanjikiza, komanso momwe magawowo amawonekera. Njirazo ziyenera kusinthidwa kuti ziwonjezeke nthawi zochizira, kutengera osati ma geometries a kapangidwe kake, komanso mtundu wa zida zomwe zimagwiritsidwa ntchito.

Kodi mumawonetsetsa bwanji kuti zomatira za LED zachira kwathunthu?

Chomatira cha LED chikachiritsidwa bwino, chimapanga malo olimba komanso osasunthika omwe amakhala osalala agalasi. Nkhani yoyesa kuchiritsa pamafunde ataliatali ndi vuto lotchedwa oxygen inhibition. Kutsekereza kwa okosijeni kumachitika pamene mpweya wa mumlengalenga uletsa njira ya free-radical polymerization yomwe imachiritsa pafupifupi zomatira zonse za UV. Zimapangitsa kuti pakhale malo ovuta, ochiritsidwa pang'ono.

Kuletsa kwa okosijeni kumawonekera kwambiri pazogwiritsa ntchito zomwe zilibe chotchinga cha mpweya wa mumlengalenga. Mwachitsanzo, kuletsa kwa okosijeni kumakhala koipitsitsa kwambiri pakupaka kovomerezeka ndi mankhwala otsegula panja kuposa momwe zikanakhalira poika zomatira pakati pa zigawo za galasi.

Kodi zina mwazabwino zotani za chitetezo cha zomatira zochiritsira za LED motsutsana ndi kuchiritsa kwa UV?

Kuwala kwa UV kumatha kuyambitsa vuto lachitetezo chifukwa kumatha kuyambitsa kuyaka kwa khungu ndi kuvulala kwamaso; Ngakhale nyali za LED zikufunikabe kugwiritsidwa ntchito ndi zida zodzitetezera, sizikhala pachiwopsezo chofanana ndi chomwe anzawo akuchiritsa a UV.

Ndi makina otani apadera omwe Master Bond amapereka mankhwala omwe ali ndi nyali ya LED?

Mndandanda wa Master Bond LED 400 umapereka zinthu zingapo zofunika zaumisiri ndipo kutengera giredi, zitha kugwiritsidwa ntchito polumikizira, kuyika, ndi zokutira. Chogulitsa chatsopano kwambiri pamndandandawu ndi LED405Med.
