Iyini imbangela eyinhloko yokusebenzisa izinti zokukhanyisa ze-LED ngaphezu kwezinti zokukhanyisa ezilaphekayo ze-UV?
Izinamathiseli ze-LED ezipholishayo zivame ukupholisha ngemizuzwana engama-30-45 ngaphansi komthombo wokukhanya ongu-405 nanometer (nm). Izinamathiseli zendabuko ezipholishayo ukukhanya, ngokuphambene, zipholisha ngaphansi kwemithombo yokukhanya ye-ultraviolet (UV) enama-wavelength aphakathi kuka-320 no-380 nm. Kwabanjiniyela bokuklama, ikhono lokupholisa ngokuphelele izinamathiseli ngaphansi kokukhanya okubonakalayo livula uhla lwezinhlelo zokubopha, zokufaka kanye nokuvala ezazingafanele imikhiqizo yokupholisa ukukhanya, ngoba ezinhlotsheni eziningi izisekelo zingase zingadlulisi ku-wavelength ye-UV kodwa zivumele ukudluliselwa kokukhanya okubonakalayo.
Yiziphi ezinye zezici ezingathinta isikhathi sokwelashwa?
Ngokuvamile, ukukhanya kwesibani se-LED kufanele kube phakathi kuka-1 no-4 watts/cm2. Okunye okucatshangelwayo ibanga elisuka esibanini liye ongqimbeni olunamathelayo, isibonelo, uma isibani siqhelelene ne-glue, isikhathi sokulungisa siba side. Ezinye izinto okufanele uzicabangele ubukhulu bengqimba yokunamathelayo, ungqimba oluncane luzolulama ngokushesha kunengqimba ekhudlwana, nokuthi ama-substrate abonakala kanjani. Izinqubo kumele zilungiswe ukuze zithuthukise izikhathi zokulungisa, hhayi nje kuphela kumajiyometri omklamo ngamunye, kodwa futhi nohlobo lwemishini esetshenziswayo.
Uqinisekisa kanjani ukuthi inhlaka ye-LED ipholile ngokuphelele?
Uma ingcina ye-LED iqiniswe ngokuphelele, yakha indawo eqinile futhi engaqini kahle ebushelelezi njengengilazi. Inkinga ngemizamo yangaphambilini yokwelapha ngamaza amade yisimo esibizwa ngokuthi inqanda ye-oxygen. Inqanda ye-oxygen yenzeka lapho i-oxygen esemoyeni ivimbela inqubo ye-free-radical polymerization elapha cishe zonke ingcina ze-UV. Kuphumela endaweni eqinisiwe, eqiniswe kancane.
Ukuvinjelwa komoya-mpilo kubonakala kakhulu ezisetshenzisweni ezingenawo umgoqo kumoya-mpilo womoya-mpilo womoya. Isibonelo, ukuvinjelwa komoya-mpilo kungaba kubi kakhulu ekusetshenzisweni kwe-conformal coating enomoya ovulekile kunokuba kube njalo ekusetshenzisweni okufaka ingcina phakathi kwezingqimba zengilazi.
Yiziphi ezinye zezinzuzo zokuphepha zezinamathiseli ze-LED ezikhazimulayo uma kuqhathaniswa nezika-UV?
Izibani ze-UV zingase zibe yinkinga yokuphepha njengoba zingabangela ukusha kwesikhumba nokulimala kwamehlo; yize izibani ze-LED zisadinga ukusetshenziswa nemishini yokuzivikela efanele, zivame ukungabi yingozi efanayo neyezinye ezisebenzisa i-UV.
Yiziphi izinhlelo ezikhethekile ezinikezwa yi-Master Bond ngaleyo ndlela yokwelapha ngokukhanya kwe-LED?
Uchungechunge lwe-Master Bond LED 400 lunikeza uhla lwezakhiwo zobunjiniyela ezifiselekayo futhi kuye ngebanga, lungasetshenziswa ekubopheni, ekuhlanganiseni, nasekumbozeni. Umkhiqizo omusha ochungechungeni yi-LED405Med.
