Zombini i-UV (ultraviolet) kunye ne-EB (electron beam) zisebenzisa i-electromagnetic radiation, eyahlukileyo kwi-IR (infrared) heat curing. Nangona i-UV (Ultra Violet) kunye ne-EB (Electron Beam) zine-wavelengths ezahlukeneyo, zombini zinokubangela i-chemical recombination kwi-sensitizers ze-inki, oko kukuthi, i-high-molecular crosslinking, nto leyo ebangela i-instantly curing.
Ngokwahlukileyo koko, i-IR curing isebenza ngokufudumeza i-inki, ivelisa iziphumo ezininzi:
● Ukufuma komphunga womlinganiselo omncinci wesinyibilikisi okanye ukufuma,
● Ukuthambisa umaleko weinki kunye nokuhamba kwamanzi okwandileyo, okuvumela ukufunxwa nokomiswa,
● Ukuxinana komphezulu okubangelwa kukufudumeza kunye nokudibana nomoya,
● Ukulungiswa kweekhemikhali ezinyibilikisa iiresini kunye neeoyile ezineemolekyuli ezininzi phantsi kobushushu obuphantsi kweekhemikhali.
Oku kwenza ukuba i-IR clinic ibe yinkqubo yokomisa enamacala amaninzi nengaphelelanga, endaweni yokuba ibe yinkqubo enye epheleleyo yokucoca. Ii-inki ezisekelwe kwi-solvent zahlukile kwakhona, njengoko ukucoca kwazo kufezekiswa nge-100% ngokufuma kwe-solvent encediswa kukuhamba komoya.
Umahluko Phakathi koNyango lwe-UV kunye ne-EB
Ukunyanga kwe-UV kwahlukile ekunyanga kwe-EB ikakhulu kubunzulu bokungena. Imisebe ye-UV inokungena okulinganiselweyo; umzekelo, umaleko we-inki obunzima obuyi-4–5 µm ufuna ukunyanga okucothayo ngokukhanya kwe-UV okunamandla aphezulu. Awunakunyangwa ngesantya esiphezulu, njengeeshiti ezili-12,000–15,000 ngeyure kushicilelo lwe-offset. Ngaphandle koko, umphezulu unokunyangwa ngelixa umaleko ongaphakathi uhlala umanzi—njengeqanda elingaphekwanga kakuhle—okunokubangela ukuba umphezulu uphinde unyibilike kwaye unamathele.
Ukungena kwe-UV kuyahluka kakhulu ngokuxhomekeke kumbala we-inki. Iinki ze-Magenta kunye ne-Cyan zingena lula, kodwa ii-inki eziMthubi neziMnyama zifunxa uninzi lwe-UV, kwaye i-inki emhlophe ibonisa i-UV eninzi. Ke ngoko, ukulandelelana kombala kwiprinta kuchaphazela kakhulu ukucinywa kwe-UV. Ukuba ii-inki eziMnyama okanye eziMthubi ezine-UV ephezulu ziphezulu, ii-inki eziBomvu okanye eziLuhlaza ezingaphantsi zinokunganyangeki ngokwaneleyo. Ngokwahlukileyo koko, ukubeka ii-inki eziBomvu okanye eziLuhlaza phezulu kunye neziMthubi okanye eziMnyama ngaphantsi kwandisa amathuba okucinywa ngokupheleleyo. Ngaphandle koko, umaleko ngamnye wombala unokufuna ukucinywa okwahlukileyo.
Kwelinye icala, i-EB curing ayinayo imibala eyahlukeneyo exhomekeke ekukhanyeni kwaye inokungena okunamandla kakhulu. Ingangena ephepheni, eplastikini, nakwezinye izinto ezingaphantsi komhlaba, kwaye iphilise namacala omabini oshicilelo ngaxeshanye.
Izinto ezikhethekileyo eziqwalaselwayo
Ii-inki ezimhlophe ezingaphantsi komhlaba zinzima kakhulu ekukhanyeni kwe-UV kuba zibonisa ukukhanya kwe-UV, kodwa ukukhanyela kwe-EB akuchaphazeleki koku. Le yenye inzuzo ye-EB kune-UV.
Nangona kunjalo, ukunyanga nge-EB kufuna ukuba umphezulu ube kwindawo engenaoksijini ukuze kufezekiswe ukusebenza kakuhle kokunyanga. Ngokungafaniyo ne-UV, enokunyangeka emoyeni, i-EB kufuneka yonyuse amandla angaphezu kwalishumi emoyeni ukuze kufezekiswe iziphumo ezifanayo—umsebenzi oyingozi kakhulu ofuna amanyathelo okhuseleko angqongqo. Isisombululo esisebenzayo kukugcwalisa igumbi lokunyanga nge-nitrogen ukususa ioksijini nokunciphisa ukuphazamiseka, okuvumela ukunyanga ngempumelelo ephezulu.
Enyanisweni, kumashishini e-semiconductor, ukuthathwa kwe-UV kunye nokuvezwa kudla ngokwenziwa kwiindawo ezizaliswe yi-nitrogen, ezingenayo ioksijini ngesizathu esifanayo.
Ngoko ke, i-EB curing ifanelekile kuphela kwiiphepha ezincinci okanye iifilimu zeplastiki ezisetyenziswa kwiingubo zokugquma nokuprinta. Ayifanelekanga kwiimashini ezifakwe amaphepha ezineetyathanga zoomatshini kunye neegrippers. I-UV curing, ngokuchaseneyo, ingasetyenziswa emoyeni kwaye iluncedo ngakumbi, nangona i-UV curing engenaoksijini ingasetyenziswa rhoqo kwiingubo zokuprinta okanye zokugquma namhlanje.
