Ulwazi loMshini wokuPrinta we-UV

Ukuprintwa kwe-UV

I. Ingcamango ye-UV

I-UV imeleUmsebe we-Ultra-VioletImithombo yokukhanya kwe-UV yemizi-mveliso igubungela uluhlu lwe-spectral oluyi-200nm-450nm, oluphinde lwahlulwe kwiindidi ezilandelayo ze-wavelength:

·UV A: 320-400nm

·UV B: 290-320nm

·UV C: 200-290nm

·I-UVV: 390nm nangaphezulu

II. Unyango lwe-UV

Unyango lwe-UV, ekwabizwa ngokuba yi-UV Coating, yinkqubo ye-photochemical. Ibandakanya ukusetyenziswa kwezinto zolwelo ezinokunyangeka kwi-UV kwi-substrate okanye kumphezulu we-workpiece, apho ziqina khona phantsi kokukhanya kwe-UV. Oku kwahlukile kwiinkqubo zemveli zokumisa. Ngelixa iindlela zemveli zixhomekeke ekuphumeni kwe-solvents ukuze ziqine, i-UV coating idibanisa izinto ngaphandle kwesidingo sokukhupha i-solvent evaporation.

III. Izibane ze-UV

izibane ze-UVizibane zokukhupha igesi, ezinokwahlulwahlulwa zibe ziintlobo ezimbini:

1. Izibane zokukhupha i-Arc

Ezi zibane zisebenza ngokungenisa inani elincinci le-high-purity mercury kwityhubhu ye-vacuum quartz. Umahluko we-voltage usetyenziswa phakathi kwee-electrodes kuzo zombini iziphelo, nto leyo ebangela ukukhutshwa kwe-ion, nto leyo evelisa imisebe ye-ultraviolet. Izibane ze-arc discharge zihlala zikhupha ukukhanya kwe-ultraviolet okushisa okuphezulu, okubizwa ngokuba kukukhanya kwe-thermoluminescent ultraviolet.

2. Izibane zokukhupha ukukhanya

Ngokwahlukileyo koko, izibane ezikhupha ukukhanya zinomaleko omncinci we-mercury ogquma iindonga zangaphakathi zetyhubhu ye-vacuum fluorescent. Umahluko we-voltage usetyenziswa kuzo zonke ii-electrodes, nto leyo ebangela ukukhutshwa kwe-ion okuvelisa imitha ye-ultraviolet. Izibane ezikhupha ukukhanya zikhupha ukukhanya kwe-ultraviolet okuphantsi kobushushu, okwaziwa ngokuba kukukhanya kwe-ultraviolet okubandayo.

Iingenelo eziphambili zeeMashini zokuPrinta ze-UV

·Unyango Olukhawulezileyo:Inkqubo yokunyanga nge-UV iqinisekisa ukuba iiprinti azihlali ixesha elide kuphela kodwa zikwakhanya, kunye nomaleko okhuselayo ofakwe kwiprinti, nto leyo eyandisa ukuqina kwayo kunye nokuqaqamba kombala.

·Iiprinti ezikumgangatho ophezulu:Iiprinta ze-UV zibonelela ngokuchanekileyo okuphezulu, zivelisa imifanekiso ecacileyo nebukhali, nto leyo eyenza ukuba zilungele uluhlu olubanzi lwezicelo, kubandakanya intengiso, ukupakisha, kunye nokuprinta ubugcisa obuhle.

·Isantya Esandisiweyo:Iiprinta ze-UV zibonelela ngenzuzo enkulu yesantya kuneendlela zokuprinta zemveli. Ukuprinta kwendabuko kudla ngokufuna ukuba i-inki yome ngokwendalo, inkqubo enokuthabatha ixesha elide kwaye inokubangela umonakalo kwizinto eziprintiweyo. Ukuprinta kwe-UV, kwelinye icala, kusebenzisa ukukhanya kwe-ultraviolet ukunyanga i-inki ngoko nangoko, kunciphisa kakhulu ixesha lemveliso. Olu buchule luyinzuzo enkulu yokhuphiswano kumashishini afuna amaxesha okusebenza ngokukhawuleza.

Ngokususa isidingo sexesha elide lokomisa, ukuprinta nge-UV kuphucula imveliso kunye nomgangatho, kubonelela amashishini ngesisombululo esikhawulezayo nesingabizi kakhulu kwimisebenzi yokuprinta ephezulu.
