Kulula-okumsulwa—Ukwenza kanjani ukukhiqizwa kwamalebula okunamathelayo kudlule ebusika kahle?

Indlela yokwenza ukukhiqizwa kwamalebula okunamathelayo kuhambe kahle ebusika?

Ukukubeka kalula, inqubo yokukhiqiza amalebula okunamathisela ihlanganisa izinqubo ezintathu: ukucindezela kwangaphambili, ukuphrinta kanye nokucubungula kokuthunyelwe. Ukucutshungulwa kwe-post press kuhilela izinqubo eziningi, ezihlanganisa i-lamination, ukugxiviza okushisayo, ukusika ukufa, ukuhlukanisa, njll. Kuyo yonke inqubo yokukhiqiza, izinga lokushisa lemvelo linomthelela omkhulu kwikhwalithi nokusebenza kwemikhiqizo yelebula yokunamathisela. Isibonelo, indinganiso yemboni yemishini i-JB/T 9111-1999, "Umshini Wokuphrinta Welebula Enamathelayo" idinga ukuthi izinga lokushisa lendawo yokuphrinta libe ngu-20 ℃± 2 ℃, kanye nezinga lemboni yezokunyathelisa neyokushicilela CY/T 93-2013, "Printing Technology , Ikhwalithi Yelebula Enamathelayo kanye Nezindlela Zokuhlola" idinga ukuthi izinga lokushisa lokuhlola libe ngu-23 ℃± 5 ℃. Kodwa-ke, isimo sangempela samabhizinisi amaningi okunyathelisa kunzima ukufeza izinga lokushisa elifanele lokunyathelisa, elizokhiqiza uchungechunge lwezinkinga zekhwalithi yomkhiqizo.

Ukuhlaziywa kwenkinga:

I-No.1 izinto zokusetshenziswa, njengoba kuboniswe kuMfanekiso 1, izinto eziningi zokunamathisela zongqimba lweglue lwelebula lokuzinamathisela ama-polymer ephilayo, ancike kakhulu ekushiseni. Ngamanye amazwi, izakhiwo zabo zemishini kanye ne-viscoelasticity ziyahlukahluka ngokuya ngezinga lokushisa lendawo yangaphandle kanye nezinga lokushisa lendawo yokugcina umkhiqizo, Khetha futhi ulungise izinto ezinamathelayo ezine-viscosity yokuqala ehlukile nokugcinwa kwe-viscosity ukuze zivumelane nezimo ezihlukene zokusetshenziswa futhi uqhubeke uhlangabezana nezidingo zamakhasimende imikhiqizo.

Ukuphrinta kwe-No.2, izinga lokushisa le-ambient nalo linomthelela omkhulu ekuphrinteni. Ikakhulukazi ebusika, lapho kungabikho ukushisa nomoya, izinga lokushisa langaphandle liphansi, okuholela ekushiseni okuphansi kwemishini, uyinki nezinto zokunyathelisa. Thatha ukuphrinta kwe-offset njengesibonelo, umgomo wayo wokuphrinta uwukuqedela ukudluliswa kwe-inki ngebhalansi kayinki namanzi, okungukuthi, isilinda sepuleti lokuphrinta kuqala ukuxhumana ne-roller yamanzi, ukuze ingxenye engeyona ingcaca ye-hydrophilic yepuleti yokuphrinta iqale iniselwe. , bese kuthintwa i-roller kayinki, ukuze ingxenye eyisithombe inoyinki, khona-ke uyinki wengxenye yesithombe epuleti lokunyathelisa udluliselwa kuqala engubeni, bese isilinda sengubo sidlulisela isithombe sikayinki endaweni yokunyathelisa ngaphansi kwesenzo sika- i-pressure roller. Uma izinga lokushisa lomshini nemishini liphansi, umphumela wokudlulisa uzothinteka kakhulu. Ngesikhathi esifanayo, izinga lokushisa eliphansi likayinki lizoholela ku-viscosity ephezulu kanye ne-fluidity ephansi ye-inki, okuzovimbela uyinki ukuba ugeleze kahle phakathi kwama-roller ayinki, okuholela ekudlulisweni kweyinki akubusheleli futhi iyunifomu, okuholela ekutheni umbala weyinki ongalingani endaweni yokuphrinta, okuzothinta umphumela wesithombe ezintweni zokuphrinta futhi kunciphise inani lendaba ephrintiwe. Njengoba kukhonjisiwe kuMfanekiso 2 nakuMdwebo 3, amaphutha wendawo wemikhiqizo emibili eyahlukene ayaboniswa. Phakathi kwazo, uhlangothi lwesokudla lwebhakhodi kuMfanekiso 2 lunokukhubazeka kokuphrinta, futhi uhlangothi olungaphezulu lukayinki wenkundla ye-magenta kuMfanekiso 3 lunokukhubazeka kokuphrinta.

Umfanekiso 2 Isici sokuphrinta kwesokudla sebhakhodi

Umfanekiso  3 Amaphutha okuphrinta ohlangothini olungaphezulu lukayinki wenkundla ye-magenta

I-NO.3 i-die-cutting, ikhwalithi yomphumela wokusika ukufa ayihlobene kuphela nezinkinga zepuleti lokusika i-die-cutter ngokwayo kanye nokucindezela, kodwa futhi izinga lokushisa elingaphandle elizungezile lizothinta inqubo yokukhiqiza yokufa. Ukusika okuqondile kusho ukuthi ummese wokusika uvele usike indwangu engaphezulu kanye nongqimba lweglue (njengoba kukhonjisiwe kuMfanekiso 4), kuyilapho ukusika ukufa okungafanele kungahlukaniswa ngezimo ezimbili: ukusika ukufa okungashoni (njengoba kuboniswe kuMfanekiso 5) kanye nokusika okujulile (njengoba kukhonjisiwe kuMfanekiso 6). Phakathi kwazo, ukusika okungajulile kubangela ukuthi amalebula asuswe yizicucu, futhi ukusika ukufa okujulile kubangela ukuba iphepha elingaphansi liphuke noma lithathwe ngamalebula. Lapho izinga lokushisa elizungezile liphansi, uketshezi lwe-adhesive ku-self-adhesive material kunciphisa, okuholela ekwehlulekeni kokusika ungqimba lweglue kahle ngesikhathi sokusika ukufa, okuzoholela esimweni sokwenqatshwa kwelebula, okuyinto engekho. kunciphisa kuphela isivinini sokukhiqiza, kodwa futhi kuthinta ikhwalithi yomkhiqizo.

Umfanekiso 4 I-Die cutter ivele inqume i-surface material kanye nongqimba lweglue

Umfanekiso 5 Ukusika okujulile

Umfanekiso 6 Ukusika ukufa okujulile
