Pepa rakadhindwa kaviri rakapfava uye rinopindirana, rine pfungwa yehumambo.Zvakadaro, kudhinda kwebepa rine mabhande maviri hakuna kunaka, saka nyaya dzakati wandei dzinofanira kucherechedzwa mukudhindwa kwemabhande maviri.
1. yakavharidzirwa kaviri-yakanamatira pepa, nekuda kwehurombo dhigirii yekaviri-adhesive bepa saizi pamusika, nyore kubvisa bvudzi nehupfu, saka mukusarudza inki inofanira kusarudza yakapfava inki kudhinda.Ingi yakaoma, inki inopenya zvakare iri nyore kukwevera pamusoro pehupfu hwepepa uye bvudzi rebepa, zvichikonzera kuti gumbeze rerabha riunganidzwe, kutamisa kwakashata, inki yemvura, kusashanda zvakanaka, kurasikirwa kwepepa, gumbeze rerabha uye chiyero chekupfeka kwendiro yekudhinda. murombo.Mukuwedzera, kudhindwa kwekudhinda kunofanira kuva pakati, kwete zvikuru.Uye gumbeze rerubha rinofanira kusarudza nzvimbo iri nani yerabha, isiri nyore kukuvadza, kusimba kwakanaka kwegumbeze rerubha.
2. Matambudziko ekupinza mapepa maviri-adhesive, kaviri-adhesive bepa mugadziri wepaviri-adhesive bepa rine yakasimba inki kunyura, kunyura kwemvura, saka kusarudzwa kweinki kunofanira kusarudza yakakwira dhigirii yemuvara uye inogona kupinda mukati yakaoma inki.Kana iyo color concentration isiri yakakwira, inki layer yakakora, bepa rinotora mvura yakawanda parinodhinda, uye ingi nebepa zvinooma zvishoma nezvishoma.Uyezve, kana ingi pamusoro firimu kuomeswa nokukurumidza, zvinogona kukanganisa pasi bepa kupinda kuomeswa, zvichiita kuti kudhinda pamusoro kuomeswa, kutema bepa, kusunga uye mamwe maitiro anokonzerwa bepa haana kuoma mukati uye mamwe matambudziko.
3. Bepa rinonamira kaviri PH kukosha, sezvo kukosha kwePH kwepepa rinonamira kaviri pamusika rine acid isina simba, saka mhinduro yekunyorovesa yekudhinda haigone kuve yakanyanyisa acid, PH kukosha kunowanzo kuiswa pa5.5, iyo concentration inoiswa pa. inenge 12-15%, iyo inobatsira kudhinda nekuomesa.Pamusoro pezvo, mukudhinda, kutonga kwakasimba kwemvura, inki yekutanga nguva yemvura level uye inki level haifanirwe kunge yakanyanya kukwirira.Panyaya yokudhinda mahwendefa havagoni kutsungirira tsvina, mvura uye ingi mugove anofanira kuva zvishoma sezvinobvira kuitira kukurumidza kusvika ingi pachiyero, mvura neingi kuva shoma, kudhinda kuva shoma.
Hazvina kudikanwa kusungirira 150 network, 133 network, dzimwe nguva mitsara mazana maviri ekudhinda mhinduro dziri nani.Mukuwedzera kune pre-pre-press production, flatness yemativi maviri epepa inoitawo mutsauko mukuru, rutivi rwakashata rwemufananidzo wakadhindwa rwakaoma kutarisa kusingagoneki.Nokudaro, edza kusarudza kunaka kwakanaka kwepepa.Kaviri-yakavharidzirwa mapepa ekugadzira mapepa akavharidzirwa kaviri mavara ekudhinda mavara akanaka kwazvo mamiriro ezvinhu akanaka: kuitira kuti uve nechokwadi chemhando yezvigadzirwa zvakadhindwa kuti zvienderane nezvinodiwa nevatengi, unoda kudzora imwe neimwe link.Kaviri-yakavharidzirwa mapepa ekudhinda ndiro yehutano kutonga, kudhinda, kuwedzera zvishoma kuratidzwa kwechokwadi, kuitira kuti madotsi ari mundiro pane madotsi ari pafirimu zvishomanana kuti atsigire kuwedzera kwemadota anokonzerwa nekumanikidzwa panguva yekudhinda.
Mukuita kubika ndiro, ndiro iri mukutonhodza kubva kunotonhora uye yozopisa, inobudisa iyo inoenderana elongation, shrinkage phenomenon.Nokudaro, kuitira kuti tive nechokwadi chekunyanya kudhindwa, mukudhinda-mavara akawanda kazhinji hakubvumirwi.Huwandu hwemahwendefa akagadziridzwa hunofanirwa kuve nehunyanzvi uye hwakarurama, uye kuderedza huwandu hweakagadziriswa mahwendefa kuti udzivise kuwedzeredza kusingaite nekuda kwekurebesa kwekugadzira uye deformation yendiro yekudhinda.Mamiriro ekudhinda emugadziri akaputirwa kaviri: wetting solution PH kukosha kwekutonga pa5.5 ~ 6.5.Kana iyo PH kukosha kwemhinduro yekunyorova ikasadzorwa zvakanaka, zvinokanganisa kuomeswa kweinki nemhando yekudhinda.Paunenge uchidhinda, kudzora kwakasimba kwemarongerwo ehunyoro, kuchengetedza kuenzana kweinki neingi, kuwana "inki diki yakaoma mvura" yakanaka kwazvo mamiriro ekudhinda.Wekishopu tembiricha uye humidity control.
