Izibonelelo ze-UV / i-LED yokuNyanga i-Adhesives

Sesiphi esona sizathu siphambili sokusebenzisa izinto zokuncamathelisa ze-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 bamaza. 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 osuka kwisibane ukuya kumaleko wokuncamathelisa, umzekelo, okukhona kude isibane ukusuka kwincangathi, ixesha elide lokunyanga. Ezinye izinto ezinokuthi zithathelwe ingqalelo bubunzima bomaleko wokuncamathelisa, umaleko omncinci uya kunyanga ngokukhawuleza kunomaleko otyebileyo, kunye nendlela ecace ngayo 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.

Ukuvinjelwa kwe-oksijeni kubonakaliswe kakhulu kwizicelo ezingenayo umqobo kwi-oksijeni ye-atmospheric. Ngokomzekelo, ukuthintela i-oksijini kuya kuba kubi kakhulu kwisicelo sokugquma ngokusemthethweni kunye nonyango oluvulekileyo lomoya kunokuba bekuya kuba kwisicelo esibeka i-adhesive phakathi kweengqimba zeglasi.

Zeziphi ezinye zeenzuzo zokhuseleko zokuncamathelisa kwe-LED ngokuchasene nokunyanga kwe-UV?

Izibane ze-UV zinokubangela umba wokhuseleko njengoko zinokubangela ukutshisa kwesikhumba kunye nokulimala kwamehlo; Nangona izibane ze-LED zisafuneka zisetyenziswe kunye nezixhobo ezifanelekileyo zokuzikhusela, zihlala zingafaki inqanaba elifanayo lomngcipheko owenziwa ngabalingane babo be-UV.

Zeziphi iinkqubo ezizodwa ezinikezelwa yi-Master Bond ekunyangeni ngesibane se-LED?

I-Master Bond ye-LED ye-400 series inikezela uluhlu lwezinto ezinqwenelekayo zobunjineli kwaye ngokuxhomekeke kwibakala, zingasetyenziselwa ukudibanisa, i-encapsulation, kunye nokwaleka. Imveliso entsha kuluhlu yi-LED405Med.
