Ukuprintwa kwe-inki ye-UV ngokuqhelekileyo kuthatha indlela yokomisa ngokukhawuleza kwe-UV, ukuze i-inki ikwazi ukubambelela ngokukhawuleza kumphezulu wefilimu yokuzincamathela. Nangona kunjalo, kwinkqubo yoshicilelo, ingxaki yokuncamathelwa kakubi kwe-inki ye-UV kumphezulu wefilim zokuzincamathela izinto zihlala zisenzeka.
Yintoni ukunganyaniseki kakuhle kwe-inki ye-UV?
Iitheminali ezahlukeneyo zineendlela ezahlukeneyo zokuvavanya ukuncamatheliswa kakubi kwe-inki ye-UV. Nangona kunjalo, kwishishini lelebhile yokuncamathelisa, uninzi lwabathengi baya kusebenzisa i-3M 810 okanye i-3M 610 tape yovavanyo lokuncamathela inki.
Iikhrayitheriya zokuvavanya: Ukuqina kwe-inki kuvandlakanywa ngokobungakanani be-inki enamathele emva kokuba iteyiphu yokuncamathela ibambeke kumphezulu weleyibhile ize isuswe.
Inqanaba 1: akukho inki ewayo
Inqanaba 2: I-inki encinci iyawa (<10%)
Inqanaba 3: ukuchithwa kwe-inki ephakathi (10% ~30%)
Inqanaba 4: ukuchithwa kwe-inki enzulu (30% ~ 60%)
Inqanaba lesi-5: phantse yonke inki iyawa (> 60%)
Umbuzo woku-1:
Kwimveliso, sihlala sidibana nengxaki yokuba xa ezinye izinto ziprintwa ngokuqhelekileyo, ukunamathela kwe-inki kulungile, kodwa emva kokuba isantya sokushicilela siphuculwe, ukunamathela kwe-inki kuba kubi.
unobangela1:
Njengoko i-photoinitiator kwi-inki ye-UV ifunxa ukukhanya kwe-UV ukuvelisa iiradicals zasimahla, iyakuwela ikhonkco kunye ne-monomer prepolymer kwicandelo le-inki ukwenza ulwakhiwo lwenethiwekhi, eyinkqubo yexeshana ukusuka kulwelo ukuya kokuqinileyo. Noko ke, ekushicileleni kokwenene, nangona umphezulu we-inki woma ngoko nangoko, kwakunzima ukuba ukukhanya kwe-ultraviolet kugqobhoze umaleko we-inki oqinileyo ukuya kufikelela kumaleko asezantsi, nto leyo eyayibangela ukusabela okungaphelelanga kwe-photochemical ye-inki esemazantsi.
Ingcebiso:Kwi-inki enzulu kunye noshicilelo olukhanyayo, i-inki yokuqina kombala ophezulu ingasetyenziselwa ukunciphisa ubukhulu bomaleko we-inki, engenakuqinisekisa kuphela ukoma kwe-inki yomgca omnye, kodwa iphucula ngokufanelekileyo ukusebenza kakuhle kwemveliso.
unobangela2:
Isibane se-UV mercury sisetyenziswa ngokubanzi malunga neeyure ze-1000, kwaye sinokukhanyiswa emva kokuba isibane se-UV sisetyenziswe ngaphezu kweeyure ze-1000, kodwa i-inki ye-UV ayinako ukoma ngokupheleleyo. Ngapha koko, nje ukuba isibane se-UV sifikelele kubomi baso benkonzo, ijika le-spectral litshintshile. Ukukhanya kwe-ultraviolet okukhutshwayo akuhambelani neemfuno zenki eyomileyo, kwaye amandla e-infrared anyukile, okubangele ukuguqulwa kwezinto eziphathekayo kunye nokuguqulwa kwe-ink ngenxa yokushisa okuphezulu.
Ingcebiso:Ixesha lokusetyenziswa kwesibane se-UV kufuneka sibhalwe ngokuchanekileyo kwaye sitshintshwe ngexesha. Ngexesha lemveliso eqhelekileyo, kuyimfuneko ukujonga rhoqo ukucoceka kwesibane se-UV kunye nokucoca isibonisi. Ngokubanzi, kuphela i-1/3 yamandla esibane se-UV ekhanyisa ngokuthe ngqo kumphezulu wezinto ezibonakalayo, kwaye i-2/3 yamandla ibonakaliswa sisibonisi.
umbuzo 2:
Kwimveliso, sihlala sidibana nengxaki yokuba xa ezinye izinto ziprintwa ngokuqhelekileyo, ukunamathela kwe-inki kulungile, kodwa emva kokuba isantya sokushicilela siphuculwe, ukunamathela kwe-inki kuba kubi.
Isizathu 1:
Ixesha elifutshane loqhagamshelwano phakathi kwe-inki kunye ne-substrate likhokelela ekudibaneni kwenqanaba lemolekyuli phakathi kwamaqhekeza, okuchaphazela ukunamathela.
Iinqununu ze-inki kunye ne-substrate zisasazeka kwaye zidibanise omnye nomnye ukwenza uxhumano lwenqanaba le-molecular. Ngokunyusa ixesha lokudibanisa phakathi kwe-inki kunye ne-substrate ngaphambi kokumisa, umphumo wokudibanisa phakathi kweeamolekyu unokubaluleka ngakumbi, ngaloo ndlela ukwandisa inki yokubambelela.
Ingcebiso: nciphisa isantya sokushicilela, yenza i-inki idibane ngokupheleleyo ne-substrate, kwaye uphucule ukunamathela kwe-inki.
Unobangela 2:
ixesha elinganelanga lokuvezwa kokukhanya kwe-UV, okukhokelela kwi-inki engomi ngokupheleleyo, echaphazela ukunamathela
Ukwandiswa kwesantya soshicilelo kuya kunciphisa ixesha lokukhanya kwe-UV, okuya kunciphisa amandla akhanya kwi-inki, ngaloo ndlela kuchaphazela imeko yokomisa kwe-inki, okubangela ukunamathela kakubi ngenxa yokomisa okungaphelelanga.
Ingcebiso:Cothisa isantya soshicilelo, vumela i-inki yome ngokupheleleyo phantsi kwesibane se-UV, kwaye uphucule ukunamathela.
