Yiziphi izinzuzo ze-ink ye-UV?

Ukuthuthukiswa okusheshayo kwemboni yokunyathelisa akudingi nje kuphela izinga eliphezulu nokusebenza kahle, ukunciphisa izindleko, kodwa futhi akudingi ukungcoliswa kwemvelo. Uyinki we-UV ungaphrintwa kunoma iyiphi i-substrate, futhi ikhwalithi yomkhiqizo ophrintiwe iphakeme kune-solvent based and water-based gravure printing inki. Inezinzuzo ezifana nokunwetshwa kwamachashazi amancane, ukukhanya okuphezulu, ukumelana nokugqoka kanye nokuguguleka kwamakhemikhali, akukho ukungcola, umphumela omuhle wokukhiqiza amachashazi namandla okumboza, kanye nezindleko eziphansi.

一、 Incazelo yeyinki ye-UV
I-UV isifinyezo segama lesiNgisi lokukhanya kwe-ultraviolet, uyinki we-UV welashiwe futhi omisiwe, ofushanisiwe njengoyinki we-UV. Uyinki we-UV empeleni uwuyinki owuketshezi ongashintsha usuke esimweni esiwuketshezi uye esimweni esiqinile ngaphansi kobude obuthile bobude bemisebe ye-ultraviolet.
二、 Izici zoyinki we-UV
1. Isilinganiso sokusebenza kwezindleko eziphezulu zikayinki we-UV
Uyinki we-UV awunakho ukuvuthwa kwe-solvent ngesikhathi senqubo yokuphrinta, futhi izinto eziqinile zihlala zingu-100% ku-substrate. Amandla ombala nesakhiwo samachashazi ahlala engashintshiwe, futhi ugqinsi lwesendlalelo sikayinki omncane kakhulu lungafinyelela imiphumela emihle yokuphrinta. Yize uyinki we-UV ubiza kakhulu kunoyinki osuselwa ku-solvent, uyinki oyi-1kg ye-UV ingaphrinta amamitha-skwele angama-70 wento ephrintiwe, kuyilapho uyinki osuselwa ku-solvent engu-1kg ungaphrinta kuphela amamitha-skwele angama-30 wento ephrintiwe.

2. Uyinki we-UV ungama ngaso leso sikhathi futhi unokukhiqiza okuphezulu ukusebenza kahle
Uyinki we-UV ungaqinisa futhi wome ngokushesha ngaphansi kwemisebe ye-ultraviolet, futhi imikhiqizo ephrintiwe ingapakishwa ngokushesha futhi icutshungulwe. Ijubane lokukhiqiza liyi-120-140m/min, futhi lingasindisa futhi u-60% kuya ku-80% wendawo yokugcina.
3. Uyinki we-UV awungcolisi imvelo
Uyinki we-UV awunazo izinyibilikisi eziguquguqukayo, okungukuthi ifomula yamahhala ye-solvent engu-100%, ngakho-ke ama-organic volatiles awakhishelwa emoyeni ngesikhathi senqubo yokuphrinta. Lokhu kuhambisana nemithetho yezemvelo futhi kuphinde kuqede izindleko zokutholwa kwe-solvent.
4. Uyinki we-UV uphephile futhi uthembekile
Uyinki we-UV wuhlelo olungadingi amanzi noma izincibilikisi zemvelo. Uma uyinki usuqina, ifilimu kayinki inamandla futhi imelana namakhemikhali, ngaphandle kokulimala noma ukuxebuka okubangelwa ukuthintana namakhemikhali. Uyinki we-UV uphephile ukuthi ungawusebenzisa futhi ungonga izindleko zomshwalense kubasebenzisi. Ilungele ukupakishwa nokuphrinta izinto ezinezidingo zokuhlanzeka okuphezulu njengokudla, isiphuzo, nezidakamizwa.
5. Ikhwalithi enhle kakhulu yokuphrinta uyinki ye-UV
Phakathi nenqubo yokunyathelisa, uyinki we-UV ungagcina umbala ofanayo futhi ongaguquguquki, ungqimba lukayinki lomkhiqizo ophrintiwe luqinile, ingxenye yombala nezinto zokuxhuma azishintshile, ukuguqulwa kwamachashazi kuncane, futhi kome ngaso leso sikhathi, kukuvumela ukuthi uqedele. ukuphrinta okunemibala eminingi.

6. Uyinki we-UV unezinto ezizinzileUyinki we-UV uqina kuphela ngaphansi kwemisebe yokukhanya kwe-UV, futhi isikhathi sokungomisi ngaphansi kwezimo zemvelo cishe asipheli. Lesi sici esingasomisi siqinisekisa ukuthi i-viscosity kayinki ihlala izinzile ngesikhathi sokusebenza isikhathi eside komshini wokunyathelisa. Ngenxa yokungabikho kwe-organic matter volatilization, asikho isidingo sokuqapha i-viscosity ye-inki ukuze kuqinisekiswe inqubo yokuphrinta ebushelelezi kanye nekhwalithi yokuphrinta ezinzile. Ngakho-ke, uyinki ungagcinwa ubusuku bonke ku-inki hopper ngaphandle kokulungiswa kombala.
