Ubwino wa Ma Adhesives Ochiritsa UV/LED

Kodi chifukwa chachikulu chogwiritsira ntchito zomatira zoyeretsera za LED kuposa zomatira zoyeretsera za UV ndi chiyani?

Ma glue oyeretsera a LED nthawi zambiri amachira mu masekondi 30-45 pansi pa kuwala kwa mafunde a 405 nanometer (nm). Mosiyana ndi zimenezi, ma glue oyeretsera achikhalidwe amachira pansi pa kuwala kwa ultraviolet (UV) okhala ndi mafunde apakati pa 320 ndi 380 nm. Kwa mainjiniya opanga mapangidwe, kuthekera koyeretsera ma glue mokwanira pansi pa kuwala kooneka kumatsegula mitundu yosiyanasiyana ya ma glue, encapsulation ndi sealing applications zomwe poyamba sizinali zoyenera ku zinthu zoyeretsera kuwala, chifukwa nthawi zambiri ma substrates sangafalikire mu mafunde a UV koma amalola kuwala kooneka.

Kodi ndi zinthu ziti zomwe zingakhudze nthawi yochira?

Kawirikawiri, mphamvu ya kuwala kwa nyali ya LED iyenera kukhala pakati pa 1 ndi 4 watts/cm2. Chinthu china chomwe muyenera kuganizira ndi mtunda wochokera ku nyali kupita ku guluu, mwachitsanzo, nyali ikakhala kutali ndi guluu, nthawi yochira imakhala yayitali. Zinthu zina zofunika kuziganizira ndi makulidwe a guluu, guluu wochepa thupi umachira mwachangu kuposa guluu wokhuthala, komanso momwe zinthuzo zilili zowonekera bwino. Njirazi ziyenera kusinthidwa kuti ziwongolere nthawi yochira, osati kutengera mawonekedwe a kapangidwe kalikonse, komanso mtundu wa zida zomwe zimagwiritsidwa ntchito.

Kodi mumatsimikiza bwanji kuti guluu wa LED wachira bwino?

Guluu wa LED ukakonzedwa bwino, umapanga malo olimba komanso osamata omwe amakhala osalala ngati galasi. Vuto lomwe limabwera chifukwa cha kuyesayesa koyambirira kokonzanso pa nthawi yayitali ya mafunde ndi vuto lotchedwa kuletsa mpweya. Kuletsa mpweya kumachitika pamene mpweya wa mumlengalenga umachepetsa njira ya polymerization ya free-radical yomwe imachiritsa pafupifupi zomatira zonse za UV. Zimapangitsa kuti malowo akhale omata komanso omata pang'ono.

Kuletsa mpweya m'thupi kumachitika kwambiri m'magwiritsidwe ntchito omwe alibe choletsa mpweya m'mlengalenga. Mwachitsanzo, kuletsa mpweya m'thupi kumakhala koipa kwambiri poika chophimba cha conformal chokhala ndi chotsukira mpweya chotseguka kuposa momwe zingakhalire poika guluu pakati pa magalasi.

Kodi ubwino wina wa zomatira zoyeretsera za LED poyerekeza ndi UV ndi wotani?

Magetsi a UV angayambitse vuto la chitetezo chifukwa amatha kuyambitsa kupsa pakhungu ndi kuvulala kwa maso; ngakhale kuti magetsi a LED amafunika kugwiritsidwabe ntchito ndi zida zodzitetezera, nthawi zambiri samakhala pachiwopsezo chofanana ndi omwe amachiritsa UV.

Kodi ndi njira ziti zapadera zomwe Master Bond imapereka chithandizo chogwiritsa ntchito nyali ya LED?

Ma LED 400 a Master Bond amapereka zinthu zosiyanasiyana zofunika paukadaulo ndipo kutengera mtundu wake, angagwiritsidwe ntchito polumikiza, kuphimba, ndi kuphimba. Chinthu chatsopano kwambiri pamndandandawu ndi LED405Med.
