Zithini iingenelo ze-inki ye-UV?

Uphuhliso olukhawulezileyo lweshishini lokushicilela alufuni nje kuphela umgangatho ophezulu kunye nokusebenza kakuhle, ukunciphisa iindleko, kodwa lukwafuna nongcoliseko kwindalo esingqongileyo. I-inki ye-UV ingaprintwa nakweyiphi na i-substrate, kwaye umgangatho wemveliso eprintiweyo ungcono kune-inki zokuprinta ezisekelwe kwisinyibilikisi kunye ne-gravure ezisekelwe emanzini. Inezibonelelo ezinje ngokwandiswa kwamachaphaza amancinci, ukukhanya okuphezulu, ukumelana nokuguguleka kunye nokukhukuliseka kweekhemikhali, ukungabikho kongcoliseko, isiphumo esihle sokuvelisa amachaphaza kunye namandla okugubungela, kunye nexabiso eliphantsi.

一、 Inkcazo ye-inki ye-UV
I-UV sisifinyezo segama lesiNgesi elithetha ukukhanya kwe-ultraviolet, i-UV cured and dryed inkin, esifinyezwa njenge-UV inkin. I-UV inkin ngokuyintloko yi-inki engamanzi enokutshintsha ukusuka kwimeko engamanzi ukuya kwimeko eqinileyo phantsi kobude obuthile bemitha ye-ultraviolet.
Iimpawu ze-inki ye-UV
1. Umlinganiselo wokusebenza obiza kakhulu we-inki ye-UV
I-inki ye-UV ayinayo i-solvent volatilization ngexesha lenkqubo yokuprinta, kwaye izinto eziqinileyo zihlala ziyi-100% kwi-substrate. Amandla ombala kunye nolwakhiwo lwamachaphaza azitshintshi ngokusisiseko, kwaye ubukhulu bomaleko we-inki obuncinci kakhulu bunokufezekisa iziphumo ezilungileyo zokuprinta. Nangona i-inki ye-UV ibiza kakhulu kune-inki esekelwe kwi-solvent, i-inki ye-UV eyi-1kg inokuprinta iimitha zesikwere ezingama-70 zezinto eziprintiweyo, ngelixa i-inki esekelwe kwi-solvent eyi-1kg inokuprinta iimitha zesikwere ezingama-30 zezinto eziprintiweyo.

2. I-inki ye-UV ingoma ngoko nangoko kwaye inamandla aphezulu emveliso
I-inki ye-UV inokuqina ngokukhawuleza kwaye yome phantsi kokukhanya kwemitha ye-ultraviolet, kwaye iimveliso eziprintiweyo zinokubekwa kwaye zicutshungulwe ngoko nangoko. Isantya semveliso yi-120-140m/min, kwaye inokonga i-60% ukuya kwi-80% yendawo yokugcina.
3. I-inki ye-UV ayingcolisi okusingqongileyo
I-inki ye-UV ayinazo izinyibilikisi eziguquguqukayo, oko kukuthi, ifomula engenazo izinyibilikisi eziyi-100%, ngoko ke ii-organic volatiles azikhutshelwa emoyeni ngexesha lenkqubo yokuprinta. Oku kuhambelana nemigaqo yokusingqongileyo kwaye kunciphisa iindleko zokubuyisa izinyibilikisi.
4. I-inki ye-UV ikhuselekile kwaye ithembekile
I-inki ye-UV yinkqubo engadingi manzi okanye izinyibilikisi zendalo. Nje ukuba i-inki iqine, ifilimu ye-inki inamandla kwaye iyamelana neekhemikhali, ngaphandle komonakalo okanye ukuxobuka okubangelwa kukudibana neekhemikhali. I-inki ye-UV ikhuselekile ukuyisebenzisa kwaye inokonga iindleko zeinshurensi kubasebenzisi. Ifanelekile ekupakisheni nasekuprinteni izixhobo ezineemfuno eziphezulu zococeko ezifana nokutya, iziselo, kunye namayeza.
5. Umgangatho ogqwesileyo wokuprinta i-inki ye-UV
Ngexesha lenkqubo yokuprinta, i-inki ye-UV inokugcina umbala ofanayo nofanayo, umaleko we-inki wemveliso eprintiweyo uqinile, umlinganiselo wombala kunye nezinto ezidibanisayo awutshintshi, ukuguquguquka kwamachaphaza kuncinci, kwaye komile ngoko nangoko, okuvumela ukuba kugqitywe ukushicilela okunemibala emininzi.

6. I-inki ye-UV ineempawu ezizinzileyo. I-inki ye-UV iqina kuphela xa ikhanyiswe ngokukhanya kwe-UV, kwaye ixesha lokungomi phantsi kweemeko zendalo phantse lingenasiphelo. Olu phawu lokungomi luqinisekisa ukuba i-viscosity ye-inki ihlala izinzile ngexesha lokusebenza komatshini wokuprinta ixesha elide. Ngenxa yokungabikho kokuguquguquka kwezinto eziphilayo, akukho mfuneko yokujonga i-viscosity ye-inki ukuqinisekisa inkqubo yokuprinta egudileyo kunye nomgangatho wokuprinta ozinzileyo. Ke ngoko, i-inki inokugcinwa ubusuku bonke kwi-inki hopper ngaphandle kokulungiswa kombala.
