Ziziphi iingenelo ze-inki ye-UV?

Uphuhliso olukhawulezayo lweshishini lokushicilela alufuni kuphela umgangatho ophezulu kunye nokusebenza kakuhle, ukunciphisa iindleko, kodwa kufuna ukuba akukho ngcoliseko kwindalo. I-inki ye-UV inokuprintwa kuyo nayiphi na i-substrate, kwaye umgangatho wemveliso eprintiweyo uphezulu kune-solvent based and water-based gravure printing inki. Ineenzuzo ezinjengokwandiswa kwamachaphaza amancinci, ukukhanya okuphezulu, ukumelana nokunxiba kunye nokukhukuliseka kweekhemikhali, akukho ngcoliseko, isiphumo esihle sokuvelisa amachaphaza kunye namandla okugubungela, kunye neendleko eziphantsi.

一、 Inkcazo ye-inki ye-UV
I-UV sisishunqulelo segama lesiNgesi lokukhanya kwe-ultraviolet, i-UV ephilisiwe kunye ne-inki eyomisiweyo, efinyeziweyo njenge-inki ye-UV. I-inki ye-UV yi-inki yolwelo enokuthi iguqule ukusuka kwimeko yolwelo ukuya kwimeko eqinileyo phantsi kobude obuthile bemitha ye-ultraviolet.
二、 Iimpawu ze-inki ye-UV
1. Umlinganiselo wokusebenza kweendleko eziphezulu ze-inki ye-UV
I-inki ye-UV ayinayo i-volatilization ye-solvent ngexesha lenkqubo yokushicilela, kwaye izinto eziqinileyo zihlala ziyi-100% kwi-substrate. Amandla ombala kunye nolwakhiwo lwamachaphaza luhlala lungatshintshwanga, kwaye ubungqingqwa be-inki ebhityileyo kakhulu bunokufikelela kwiziphumo ezilungileyo zoshicilelo. Nangona i-inki ye-UV ibiza kakhulu kune-inki esekwe kwi-solvent, i-1kg i-inki ye-UV inokuprinta i-70 ye-square yeemitha zento eprintiweyo, ngelixa i-1kg ye-inki esekwe kwi-solvent inokushicilela kuphela i-30 ye-square yeemitha zezinto eziprintiweyo.

2. I-inki ye-UV inokoma ngoko nangoko kwaye inemveliso ephezulu
I-inki ye-UV inokuqina ngokukhawuleza kwaye yome phantsi kokukhanya kwemitha ye-ultraviolet, kwaye iimveliso eziprintiweyo zinokuthi zifakwe ngokukhawuleza kwaye ziqhutywe. Isantya sokuvelisa yi-120-140m / min, kwaye inokugcina i-60% ukuya kwi-80% yendawo yokugcina.
3. I-inki ye-UV ayingcolisi indalo
I-inki ye-UV ayinazo izinyibilikisi eziguquguqukayo, oko kukuthi i-100% ye-solvent free formula, ngoko i-organic volatiles ayikhutshwa emoyeni ngexesha lenkqubo yokushicilela. Oku kuhambelana nemigaqo yokusingqongileyo kwaye kwakhona kuphelisa iindleko zokubuyisela i-solvent.
4. I-inki ye-UV ikhuselekile kwaye ithembekile
I-inki ye-UV yinkqubo engadingi amanzi okanye izinyibilikisi eziphilayo. Emva kokuba i-inki yomelele, ifilimu ye-inki yomelele kwaye ikwazi ukumelana neekhemikhali, ngaphandle komonakalo okanye ukuxobuka okubangelwa kukudibana neekhemikhali. I-inki ye-UV ikhuselekile ukuyisebenzisa kwaye inokugcina iindleko ze-inshorensi kubasebenzisi. Ilungele ukupakishwa kunye nezinto zokushicilela ezineemfuno eziphezulu zococeko ezifana nokutya, isiselo, kunye neziyobisi.
5. Umgangatho ogqwesileyo we-UV inki yoshicilelo
Ngexesha lenkqubo yoshicilelo, i-inki ye-UV inokugcina iyunifomu kunye nombala ongaguquguqukiyo, umaleko we-inki wemveliso eprintiweyo iqinile, ubungakanani bombala kunye nezixhobo zokudibanisa zihlala zingatshintshi, i-dot deformation incinci, kwaye yoma kwangoko, ivumela ukuba igqitywe. ukuprintwa kwemibala emininzi.

6. I-inki ye-UV ineempawu ezizinzileyoI-inki ye-UV iqina kuphela phantsi kwemitha yokukhanya kwe-UV, kwaye ixesha lokungasomisi phantsi kweemeko zendalo liphantse lingenasiphelo. Olu phawu olungasomisi luqinisekisa ukuba i-viscosity ye-inki ihlala izinzile ngexesha lokusebenza kwexesha elide lomatshini wokushicilela. Ngenxa yokungabikho kwe-organic matter volatilization, akukho mfuneko yokubeka iliso kwi-viscosity ye-inki ukuqinisekisa inkqubo yokushicilela egudileyo kunye nomgangatho ozinzileyo wokushicilela. Ngoko ke, i-inki inokugcinwa ngobusuku kwi-inki hopper ngaphandle kokulungiswa kombala.
