Sesiphi esona sizathu siphambili sokusebenzisa izinto ezincamathelayo zokunyanga i-LED ngaphezulu kwe-UV encamathelayo enyangekayo?
Izincamathelisi zokunyanga ze-LED zinyangeka ngemizuzwana engama-30 ukuya kwengama-45 phantsi komthombo wokukhanya ongama-405 nanometer (nm) ubude bobude. Izinto ezincamathelayo zokunyanga ukukhanya, ngokuchaseneyo, zinyanga phantsi kwemithombo yokukhanya ye-ultraviolet (UV) enobude obuphakathi kwe-320 kunye ne-380 nm. Kwiinjineli zokuyila, ukukwazi ukunyanga ngokupheleleyo i-adhesives phantsi kokukhanya okubonakalayo kuvula uluhlu lwe-bonding, i-encapsulation kunye nokutywinwa kwezicelo ebezingafanelekanga ngaphambili kwiimveliso zonyango olukhanyayo, kuba kwizicelo ezininzi i-substrates ayinako ukuhambisa kwi-wavelength ye-UV kodwa ivumele ukubonakala. ukuhanjiswa kokukhanya.
Ziziphi ezinye zezinto ezinokuchaphazela ixesha lokunyanga?
Ngokuqhelekileyo, ukukhanya kwesibane se-LED kufuneka kube phakathi kwe-1 kunye ne-4 watts / cm2. Olunye uqwalaselo ngumgama ukusuka kwisibane ukuya kumaleko wokuncamathelisa, umzekelo, okukhona kude isibane kwi-adhesive, ixesha elide lokunyanga. Ezinye izinto ezinokuthi zithathelwe ingqalelo bubunzima bomaleko wokuncamathelisa, umaleko omncinci uya kunyanga ngokukhawuleza kunomaleko otyebileyo, kunye nendlela ecace ngakumbi i-substrates. Iinkqubo kufuneka zilungiswe ukuze kwandiswe amaxesha okunyanga, ngokusekwe kungekuphela nje kwijometri yoyilo ngalunye, kodwa nohlobo lwezixhobo ezisetyenzisiweyo.
Uqinisekisa njani ukuba isincamathelisi se-LED sinyange ngokupheleleyo?
Xa isincamathelisi se-LED sinyangekile ngokupheleleyo, senza umphezulu oqinileyo nongacolekiyo ogudileyo njengeglasi. Umba ngeenzame zangaphambili zokunyanga kumaza amade yimeko ebizwa ngokuba kukuthintelwa kweoksijini. Uthintelo lweoksijini lwenzeka xa ioksijini esesibhakabhakeni inqanda inkqubo ye-polymerization yasimahla ephilisa phantse zonke izinto zokuncamathelisa ze-UV. Ikhokelela kwindawo ethambileyo, enyangekileyo.
