Xa usebenzisa umshicileli we-UV flatbed ukuprinta ezinye izinto, ngenxa yokoma kwangoko kwe-inki ye-UV, ngamanye amaxesha kukhokelela kwingxaki yokunamathela okuphantsi kwe-inki ye-UV kwi-substrate.Eli nqaku kukufunda indlela yokuphucula ukunamathela kwe-inki ye-UV kwi-substrate.
unyango lwe-corona
Umbhali ufumanise ukuba unyango lwe-corona yindlela enokuphucula ngokufanelekileyo ukuncamathela kwe-inki ye-UV!Ii-electrodes ezintle kunye nezingalunganga zesixhobo se-corona zisekelwe kwinqwelomoya ephantsi kunye ne-Yuden air nozzle ngokulandelanayo.Ii-electron zasimahla ezinamandla aphezulu ziyakhawuleza ukuya kwi-electrode elungileyo, enokutshintsha i-polarity yezinto ezingafunxiyo kwaye zonyuse uburhabaxa bomphezulu, ziphucule ukukwazi ukudibanisa ne-inki, ukufezekisa ukuncamathela okuchanekileyo kwe-UV, kunye nokuphucula ukuncamathela. ukuqina kwe-inki umaleko..
Izixhobo ezinyangwa ngeCorona zinozinzo olulambathayo womphezulu woxinzelelo, kwaye isiphumo se-corona siya kuba buthathaka ngokuthe ngcembe ngokuhamba kwexesha.Ngokukodwa kwindawo yokufuma okuphezulu, umphumo we-corona uya kuba buthathaka ngokukhawuleza.Ukuba ii substrates ezinyangwa ngecorona zisetyenzisiwe, intsebenziswano nomthengisi kufuneka yenziwe ukuqinisekisa ukutsha kwe substrates.Izinto eziqhelekileyo eziphathwa nge-corona ziquka i-PE, i-PP, inayiloni, i-PVC, i-PET, njl.
Umxhasi wokuncamathelisa inki ye-UV (AdhesionPromoters)
Kwiimeko ezininzi, ukucoca i-substrate ngotywala kuya kuphucula ukunamathela kwe-inki ye-UV kwi-substrate.Ukuba ukubambelela kwi-substrate kwi-inki ye-UV ihlupheke kakhulu, okanye imveliso ineemfuno eziphezulu zokubambelela kwi-inki ye-UV, unokucinga ngokusebenzisa i-primer / UV inki yokubambelela ekhuthaza ukunamathela kwi-inki ye-UV.
Emva kokuba i-primer isetyenziswe kwi-substrate engaxutywanga, ukunamathela kwe-inki ye-UV kunokuphucula ukufezekisa umphumo ofanelekileyo wokubambelela.Eyahlukileyo kunyango lwe-corona, izinto ze-primer zekhemikhali aziqukethe iimolekyuli ezinamafutha angenawo-polar, anokuphelisa ngempumelelo ingxaki yempembelelo ye-corona engazinzanga ebangelwa kukufuduka kwaloo mamolekyuli.Nangona kunjalo, ububanzi bokusetyenziswa kwe-primer bukhetha, kwaye busebenza ngakumbi kwiglasi, i-ceramic, isinyithi, i-acrylic, i-PET kunye nezinye ii-substrates.
Iqondo lokunyanga inki ye-UV
Ngokubanzi, sinokubona ukunganyaniseki kakuhle kwee-inks ze-UV kwii-substrates ezingabambiyo kwiimeko apho ii-inks ze-UV zinganyangekanga ngokupheleleyo.Ukuphucula iqondo lokunyanga inki ye-UV, ungaqala kule miba ilandelayo:
I-1) Yandisa amandla esibane sokukhanya kwe-UV.
2) Nciphisa isantya sokushicilela.
3) Yandisa ixesha lokunyanga.
4) Khangela ukuba isibane se-UV kunye nezixhobo zayo zisebenza ngokufanelekileyo.
5) Ukunciphisa ubukhulu boluhlu lwe-inki.
Ezinye iindlela
Ukufudumeza: Kushishino loshicilelo lwesikrini, kuyacetyiswa ukufudumeza i-substrate phambi kokunyangwa kwe-UV ngaphambi kokuba uprinte kwii-substrates ezinzima ukubambelela.Ukunamathela kwee-inks ze-UV kwii-substrates kunokuphuculwa emva kokufudumeza ngokukhanya okukufutshane kwe-infrared okanye ukukhanya okude kwi-15-90 imizuzwana.
I-Varnish: Ukuba i-inki ye-UV isenengxaki yokubambelela kwi-substrate emva kokusebenzisa ezi ngcebiso zingentla, i-varnish ekhuselayo ingafakwa kumphezulu wokuprinta.
