Isibane sokomisa ipeyinti yeUV

Kwintsimi yemveliso yokunyanga imveliso, ukuzinza kunye nokusebenza kakuhle komthombo wokukhanya kwe-UV kumisela ngokuthe ngqo umgangatho wemveliso. Njengesibane esiphakamileyo-sokukhupha igesi, izibane zegallium(izibane ze-uv primer curing), kunye noncedo lwazo olulodwa lwetekhnoloji, ziye zaba yeyona nto iphambili ekuqhubeni uphuculo lwemveliso yeshishini kwaye izisa utshintsho oluguqukayo kwimiba emininzi.

Yenziwe -ngequartz ecocekileyo. Isixhobo se-luminescent esine-gallium iodides ezaliswe ngokuchanekileyo ngaphakathi kunye ne-iodides yeentsimbi ezahlukeneyo ezinqabileyo, ezinokumelana nobushushu obuphezulu ngexesha le-arc yombane. Ngexesha lotshintsho oluchulumancisayo lwe-athom, kufutshane-i-ultraviolet kunye nokukhanya okuluhlaza okwesibhakabhaka-kukukhanya kweviolet kwi-350nm{15}}450nm band zikhululwa ngokuzinzileyo. Phakathi kwazo, imigca ye-spectral engundoqo ye-403nm-417nm ihambelana kakhulu nencopho yokufunxa uninzi lwezixhobo ze-photosensitive kwimizi-mveliso, ngokusisiseko iqinisekisa ukuchaneka kokuvezwa kunye neenkqubo zokunyanga. ​Umbane ubanzi ukusuka kwi-1KW ukuya kwi-24KW, enokuthi ilungelelanise ngokuguquguqukayo kwiimfuno ezahlukeneyo ukusuka kuphando oluncinci lwelabhoratri kunye nophuhliso ukuya kwimveliso enkulu yomzimveliso.

Xa kuthelekiswa nemithombo yokukhanya yemveli, uguqulo lwamandla okuphumelela ukukhanya kwe-uv primer lugqwesile, kwaye ubushushu obukufutshane be--ultraviolet buphezulu kumandla afanayo. Ayinako kuphela ukunciphisa kakhulu ixesha lokuvezwa kwepleyiti ekwenzeni ipleyiti yokushicilela kunye nomjikelo wokunyanga we-PCB solder imaski eyomileyo ifilimu, kodwa iphinda isebenze ngokugqwesileyo kwibala lokusetyenzwa kwemveliso yomthi - ukuhlangabezana neemfuno zokunyangwa kokukhanya kweprimer yomthi. Ukukhanya okukufutshane {{4} kwe-ultraviolet yezibane zokunyanga i-uv primer inokungena ngokunzulu kwi-primer coating, isebenze ngokukhawuleza ukusabela kwe-arhente ephilisayo, kwaye inqande iingxaki zokuqhekeka komphezulu kunye nokoma okungalinganiyo okuqhele ukwenzeka kwiindlela zokunyanga zesintu. Iprimer enyangisiweyo inoncamathelo eyomeleleyo kunye nokuba mcaba okuphezulu, ibeka isiseko esiphakamileyo{6} somgangatho wesicelo esilandelayo sedyasi yangaphezulu. Ngexesha elifanayo, kunokunciphisa ukusetyenziswa kwamandla ngexesha lenkqubo yokunyanga i-primer.

Kule mihla, kwiimeko ezinje ngokwenza ipleyiti ye-PS, i-PCB solder imaski yokuvezwa kwefilimu eyomileyo, ukunyangwa okukhanyayo kweeprimer zemveliso yeplanga, kunye nokunyangwa okunzulu kwepeyinti yeplanga ephezulu, izibane zegallium zibe yeyona nto ikhethwayo yokukhanya kumashishini amaninzi. Izibane zokomisa ipeyinti ye-UV azinakuphucula kuphela ukuchaneka kunye nokuhambelana komgangatho weemveliso, kodwa zikwanceda amashishini ukuba afezekise inguqu yemveliso eluhlaza ngelixa kuncitshiswa iindleko kunye nokwandisa ukusebenza kakuhle. Ukukhetha izibane ze-gallium kuthetha ukukhetha ukusebenza kakuhle okuphezulu, ukuzinza kunye nokulungelelana kokusingqongileyo, ukufaka amandla obutsha obutsha kwimveliso yemizi-mveliso.
