Mabhegi ekurongedza epurasitiki anowanzo kudhindwa pamafirimu epurasitiki akasiyana, uye obva asanganiswa nematanda ekuvharira uye kupisa-sealing layers kuti aumbe mafirimu emubatanidzwa, anochekwa nekuiswa mumabhegi kuti agadzire zvigadzirwa zvekurongedza.Pakati pavo, kudhinda ndiyo yekutanga mutsara wekugadzira uye inonyanya kukosha maitiro.Kuyera giredhi yechigadzirwa chekurongedza, mhando yekudhinda ndiyo yekutanga.Naizvozvo, kunzwisisa uye kudzora kudhinda maitiro uye mhando yave kiyi yekuchinjika kurongedza kugadzirwa.
Kune matatu anowanzo shandiswa kudhinda maitiro mukugadzira mabhegi epurasitiki:
1. Gravure kudhinda
Kudhindwa kwefirimu repurasitiki kunonyanya kuenderana neiyo gravure printing process.Firimu repurasitiki rakadhindwa negravure rine zvakanakira zvemhando yepamusoro yekudhinda, gobvu inki layer, ruvara rwakajeka, yakajeka uye inopenya pateni, rakapfuma mufananidzo layer, musiyano uri pakati nepakati, mufananidzo wakajeka uye yakasimba-matatu-dimensional pfungwa.Zvisinei, kudhinda kwegravure kunewo zvikanganiso zvisingagoni kufuratirwa, zvakadai semagadzirirwo akaoma epre-press plate-making, kudhura kukuru, kutenderera kwenguva refu, uye kusvibiswa kukuru.
2. Flexographic kudhinda
Flexographic kudhinda kunonyanya kushandisa flexographic uye nekukurumidza-kuomesa letterpress ingi.Midziyo yacho iri nyore, mutengo wakaderera, zvinhu zveplate zvine uremu huremu, kudzvanya kudiki, midziyo yeplate uye kurasikirwa kwemichina kudiki, ruzha rwekudhinda idiki, uye kumhanya kunokurumidza.Iyo flexo plate ine nguva shoma yekuchinja kweplate uye kushanda kwepamusoro.Iyo flexo ndiro yakapfava, elastic, uye ine yakanaka inki yekufambisa kuita.Iine zvinhu zvakasiyana-siyana zvekudhinda, uye mari yekudhinda mabheti maduku ezvigadzirwa yakaderera pane yegravure kudhinda.Nekudaro, kudhinda kweflexographic kune zvakakwirira zvinodiwa painki neplate zvinhu, saka mhando yekudhinda yakaderera zvishoma kune iyo gravure process.
3. Screen kudhinda
Panguva yekudhinda, kuburikidza ne extrusion ye scraper, inki inotamirwa kune substrate kuburikidza ne mesh ye graphic part kuti iite graphic yakafanana neyepakutanga.Zvigadzirwa zvekudhinda zvemasikirini zvine inki yakapfuma, mavara akajeka, mavara akazara, simba rekuvhara rakasimba, kusarudzwa kwakakura kwemhando dzeinki, kuchinjika kwakasimba, kuderera panguva yekudhinda, kushanda kuri nyore, kugadzira ndiro, uye kushomeka kwemidziyo, saka mutengo wakaderera. , Mabhenefiti akanaka ehupfumi, akasiyana-siyana ezvinyorwa zvekudhinda.
