Mu imashini zikoresha flexografiya, kumisha wino buhoro buhoro biganisha ku gusya byagiye biba ikibazo gikomeye ku bigo bicapa. Ibi ntibigira ingaruka ku bwiza bw'icapiro gusa kandi byongera imyanda, ahubwo binagabanya imikorere myiza ndetse bishobora no gutinza gahunda yo gutanga. Iki kibazo cyakemurwa gute neza? Dutanga igisubizo cyuzuye gikubiyemo guhitamo wino, kunoza uburyo ikorwamo, kuvugurura ibikoresho, no kugenzura ibidukikije kugira ngo bigufashe gukuraho gusya no kugera ku musaruro uhamye kandi ugezweho wo gucapa.

● Guhitamo wino no kunoza formula – Gukemura ibibazo byo kumisha aho bituruka
Ku mashini zicapa flexo, guhitamo no gukoresha wino ni ingenzi cyane mu gukemura ibibazo byo kumisha. Turasaba inyito zo kumisha vuba, nka inyito zishingiye ku binyabutabire zifite imiterere ihindagurika cyane cyangwa inyito zishingiye ku mazi zifite ibyuma bihutisha kurumisha. Kugira ngo humishe vuba cyane, inyito za UV zihujwe na sisitemu yo gukamura ultraviolet ni zo mahitamo meza. Guhindura ingano y'ibinyabutabire—nk'ubwiyongere bwa ethanol cyangwa ethyl acetate—bishobora kongera imikorere y'inyito mu gihe wino igumana ubudahindagurika. Byongeye kandi, guhitamo inyongeramusaruro zikwiye zo kumisha (urugero, cobalt/manganese dryer kuri oxidative drying inyito cyangwa penetrants zihariye zo gukoresha substrates zifata umwuka) bitanga umusaruro mwiza.
● Kuvugurura sisitemu yo kumisha - Kongera imikorere myiza
Imikorere ya sisitemu zo kumisha mu mashini icapa flexo igira ingaruka ku musaruro. Suzuma buri gihe ibyuma byumisha kugira ngo urebe neza ko ubushyuhe buhagaze neza (50–80°C ku byuma bishongesha, hasi gato ku byuma bishingiye ku mazi) kandi nta muyaga utemba. Ku bikoresho bisaba imbaraga nyinshi, vugurura ukoreshe infrared kumisha kugira ngo ubone umusaruro mwiza cyangwa ukoreshe UV kugira ngo wumishe ako kanya. Ibikoresho byumisha mu mwuka ukonje ni ingirakamaro cyane ku byuma bidafata irangi kugira ngo wino idasubira gutoha.
● Gutunganya Imikorere yo Gucapa – Guhindura Ibipimo by'Umusaruro
Mu mashini zicapa hakoreshejwe flexographic, kunoza ibipimo by'umusaruro byongera cyane imikorere myiza yo kumisha. Kugenzura umuvuduko wo gucapa ni ingenzi cyane—umuvuduko ukabije ubuza kumisha neza mbere y'aho icapirwa ritaha. Hindura umuvuduko ushingiye ku miterere ya wino n'ubushobozi bw'umuvuduko. Gucunga ubugari bwa filime ya wino binyuze mu guhitamo neza umuvuduko wa anilox no gukoresha ingano ya wino birinda ubwinshi bukabije. Ku icapiro ry'amabara menshi, kongera intera hagati ya sitasiyo cyangwa kongeramo ibyuma byumisha hagati ya sitasiyo byongera igihe cyo kumisha.
● Guhindura ibidukikije n'ibidukikije – Ibintu by'ingenzi byo hanze
Imiterere y'ibidukikije mu mirimo yo gucapa flexo igira ingaruka zikomeye ku kumisha. Gumana ubushyuhe bwo mu iduka kuri 20–25°C n'ubushuhe kuri 50–60%. Koresha ibikoresho bikuraho ubushuhe mu bihe by'ubushuhe. Gutunganya mbere yo gukoresha substrate (urugero: kuvura corona kuri PE/PET films) byongera uburyo wino ifatana kandi bigabanya ubusembwa bw'umusemburo.
Ubuvuzi bwa Korona
Kugenzura ubushuhe
Amaherezo, gahunda ikomeye yo kubungabunga ituma habaho umutekano mu gihe kirekire. Sukura buri gihe imiyoboro y'umuvuduko w'amazi n'ibikoresho bishyushya, urebe ko imigozi ya anilox yangiritse, kandi ukoreshe ibikoresho bipima ubwiza bw'impapuro z'umuvuduko w'amazi kugira ngo urebe ubwiza bw'inyandiko—intambwe z'ingenzi mu kwirinda ibibazo bijyanye no kumisha.
