Flexo, sekureva kunoita zita, iplate yekudhinda yeflexographic yakagadzirwa neresin nezvimwe zvinhu. Iyo tekinoroji yekudhinda tsamba. Mutengo wekugadzira ndiro wakadzikira zvakanyanya pane wesimbi yekudhinda mahwendefa akadai se intaglio copper plates. Iyi nzira yekudhinda yakarongwa pakati pezana remakore rapfuura. Zvisinei, panguva iyoyo, iyo inotsigira mvura-based inki teknolojia yakanga isati yave yakagadzirwa zvakanyanya, uye zvinodiwa zvekuchengetedzwa kwezvakatipoteredza zvakanga zvisinganyanyi kunetseka panguva iyoyo, saka kudhindwa kwezvinhu zvisingabviri hazvina kukurudzirwa.

Kunyangwe kudhinda kweflexographic uye kudhinda kwegravure kwakafanana mukuita, ese ari kusunungura, mhepo, kuchinjisa inki, kuomesa, nezvimwewo, asi kuchine misiyano mikuru yeruzivo pakati pezviviri izvi. Munguva yakapfuura, ingi dze gravure uye solvent-based inks dzine dhinda inobuda pachena. Zvirinani pane flexographic printing, ikozvino nekuvandudzwa kukuru kweinki-based inki, UV inks uye mamwe maitiro ekugadzirisa inki teknolojia, maitiro e flexographic kudhinda ari kutanga kuratidza, uye haasi akaderera kune gravure kudhinda. Kazhinji, flexographic kudhinda kune zvinotevera maitiro:

1. Mutengo wakaderera

Mutengo wekugadzira ndiro wakaderera zvakanyanya pane wegravure, kunyanya kana uchidhinda muzvikamu zvidiki, mukaha wakakura.

2. Shandisa ingi shoma

Iyo flexographic kudhinda inotora flexographic plate, uye inki inotamiswa kuburikidza neanilox roller, uye kushandiswa kweinki kunoderedzwa neanopfuura 20% kana ichienzaniswa neplate ye intaglio.

3. Kudhinda kunokurumidza uye kushanda kwakakwirira

The flexographic printing machine ine high-quality mvura-based inki inogona kusvika nyore kumhanya kwemamita 400 paminiti, nepo kudhindwa kwakajairwa kwegravure kunogona kungosvika 150 metres.

4. Kuwedzera kushamwaridzana kwezvakatipoteredza

Mukudhinda flexo, ingi-based inki, UV inks uye dzimwe ingi dzinochengetedza zvakatipoteredza dzinowanzoshandiswa, dzinonyanya kushamwaridzana nemamiriro ekunze kupfuura inki-based inki inoshandiswa mu gravure. Ikoko kunenge kusina VOCS emission, uye inogona kuva chikafu-giredhi.

Zvinoumba gravure kudhinda

1. Kudhura kukuru kwekugadzira ndiro

Mumazuva ekutanga, mahwendefa egravure aigadzirwa achishandisa nzira dzemakemikari ekuora, asi mhedzisiro yacho yakanga isiri yakanaka. Iye zvino mahwendefa e-laser anogona kushandiswa, saka kurongeka kwacho kwakakwira, uye mahwendefa anodhinda akagadzirwa nemhangura nedzimwe simbi akasimba kupfuura anochinjika resin mahwendefa, asi mutengo wekugadzira ndiro wakakwira zvakare. Yakakwirira, yakakura mari yekutanga.

2. Zvirinani kudhinda kurongeka uye kuenderana

Iyo simbi yekudhinda ndiro inonyanya kukodzera kudhindwa kwemazhinji, uye ine kuenderana kuri nani. Inokonzerwa nekuwedzera kwekupisa uye kuputika uye idiki

3. Yakakura inki kushandiswa uye yakakwirira kugadzirwa mutengo

Panyaya yekuendesa inki, kudhinda kwegravure kunoshandisa inki yakawanda, iyo inowedzera mari yekugadzira.
