Yisiphi isizathu esiyinhloko sokusebenzisa izinto zokunamathisela ezokwelapha ze-LED phezu kwezinamathelisi ezilaphekayo ze-UV?
Izinamatheliso ezilaphayo ze-LED ngokuvamile zelapheka kumasekhondi angu-30-45 ngaphansi komthombo wokukhanya we-405 nanometer (nm) wavelength. Izinamatheliso zendabuko zokwelapha ukukhanya, ngokuphambene, zelapha ngaphansi kwemithombo yokukhanya ye-ultraviolet (UV) enobude obuphakathi kuka-320 no-380 nm. Konjiniyela bokuklama, ikhono lokwelapha ngokugcwele izinto ezinamathelayo ngaphansi kokukhanya okubonakalayo livula uhla lwezinhlelo zokusebenza ezibophezelayo, zokuhlanganisa nokuvala ezazingafaneleki ngaphambilini emikhiqizweni yokwelapha ukukhanya, njengoba ezinhlelweni eziningi ama-substrates angase angadluliseli kubude begagasi be-UV kodwa avumele ukubonakala. ukudluliswa kokukhanya
Yiziphi ezinye zezinto ezingase zithinte isikhathi sokwelapha?
Ngokuvamile, ukukhanya kwesibani se-LED kufanele kube phakathi kuka-1 no-4 watts/cm2. Okunye okucatshangelwayo yibanga elisuka esibanini liye kungqimba olunamathelayo, isibonelo, lapho isibani sisuka kude ne-adhesive, isikhathi eside sokwelapha. Ezinye izici okufanele zicatshangelwe ukushuba kongqimba olunamathelayo, ungqimba oluncanyana luzophulukisa ngokushesha kunongqimba olujiyile, nokuthi ama-substrates asobala kangakanani. Izinqubo kumele zilungiswe ukuze kwandiswe izikhathi zokwelapha, zingasekelwe kuphela kujometri yomklamo ngamunye, kodwa futhi nohlobo lwempahla esetshenziswayo.
Uqinisekisa kanjani ukuthi isinamathiseli se-LED selaphe ngokuphelele?
Uma isinamathiseli se-LED selapheke ngokugcwele, sakha indawo eqinile futhi engabambeki ebushelelezi njengengilazi. Inkinga ngemizamo yangaphambili yokwelapha ngamaza amade amaza yisimo esibizwa ngokuthi ukuvinjelwa komoyampilo. Ukuvinjelwa komoyampilo kwenzeka lapho umoya-mpilo womkhathi unqanda inqubo ye-free-radical polymerization elapha cishe zonke izinto ezinamathelayo ze-UV. Kuholela endaweni ethambile, ephulukisiwe kancane.
Ukuvinjelwa komoyampilo kugqama kakhulu ezinhlelweni ezingenazo isithiyo kumoya-mpilo wasemkhathini. Isibonelo, ukuvinjelwa komoyampilo kungaba kubi kakhulu ohlelweni lokumboza oluhambisanayo olunomuthi ovulekile wokwelapha kunokuba bekungaba ohlelweni olubeka ingcina phakathi kwezingqimba zengilazi.
Yiziphi ezinye zezinzuzo zokuphepha zokunamathela kwe-LED elaphayo ngokumelene nokwelapha kwe-UV?
Izibani ze-UV zingase zibe inkinga yokuphepha njengoba zinamandla okubangela ukusha kwesikhumba nokulimala kwamehlo; nakuba izibani ze-LED zisadinga ukusetshenziswa nezinto ezifanele zokuzivikela, zivame ukungafaki izinga elifanayo lengozi eyenziwa ngozakwabo be-UV.
Yiziphi izinhlelo ezikhethekile ezinikezwa yi-Master Bond elapha ngesibani se-LED?
Uchungechunge lwe-Master Bond LED 400 lunikeza uhla lwezakhiwo zobunjiniyela ezifiselekayo futhi kuye ngebanga, lungasetshenziselwa ukubopha, ukuhlanganisa, nokumboza. Umkhiqizo omusha ochungechungeni yi-LED405Med.
