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

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.

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.
