Muchirevo chekudhinda, kusakwana kutonga pamusoro peinki viscosity kunogona kutungamirira kune akati wandei mashandisirwo enyaya?

- Kuwedzeredza Viscosity: Kana ingi viscosity yakanyanya kukwirisa, kunamira kwayo kwekuzvarwa uye tsika yekugadzira filaments refu panguva yekuchinjisa pakati pema rollers inogona kuguma neingi inobhururuka, chiitiko apo yakatyoka filament inopera inopararira mumhepo. Iyi mhedzisiro inowedzera panguva yekumhanyisa kudhinda.
- Pepa Kukuvadzwa: Ink viscosity yakakwirira inogona kudarika simba repamusoro pepepa, zvichiita kuti upfu, fibrillation, kana delamination, kunyanya kuoneka pamapepa ane zvimiro zvakasununguka uye pasi pasi simba.
- Ink Transfer Inefficiencies: Yakakwira viscosity inokanganisa kunyatsoita inki kutamisa kubva muroller kuenda kune roller uye kupinda mudhindiro ndiro kana substrate nekuda kwehukama hwakasiyana pakati peinki yekutamisa mwero uye viscosity. Izvi zvinotungamira mukugovaniswa kweinki isina kuenzana, inki isina kuvharwa, uye mapundu anooneka mumifananidzo yakadhindwa.
- Kuvhiringika kweMaitiro: Kukwiridzira kwepamusoro hakungowedzere kushandiswa kweinki uye kunokonzeresa matinji einki anononoka kuoma, asi zvakare inofambisa 背面沾脏(inki set-off) kana kunamira pakati pemapepa akadhindwa. Mukudhinda masheet-fed, pane njodzi yekuti bepa rinodhonzwa mumainki rollers.
- Low Viscosity Issues: Sezvineiwo, kana inki viscosity yakanyanya kuderera, yakawedzera fluidity (inoratidzwa seyakaonda kutaridzika) inosimudzira inki emulsification mu offset lithography, iyo inosvibisa kudhindwa nemavara asina kutariswa.
- Kupararira uye Kujeka Kuderedza: Ingi dzakadaro dzinopararira zviri nyore pamapepa, kuwedzera nzvimbo yakadhindwa, kuderedza kujeka, uye kuderedza kunamatira uye kupenya kwefirimu yakaomeswa inki kune substrate.
- Pigment Settling: Kusakwana kweviscosity kunotamburira kutakura pigment particles hombe panguva yekuendesa, zvichiita kuti zvidimbu izvi zviungane pamarora, magumbeze, kana ndiro—chirwere chinozivikanwa sokuunganidza.
