Indlela yokwandisa ingcindezi yokuthwala namandla okucindezela amabhokisi ombala wephepha likathayela? 

Njengamanje, izinkampani eziningi zokupakisha ezweni lakithi zisebenzisa izinqubo ezimbili ukuze zikhiqize amabhokisi ombala: (1) qala ngokuphrinta iphepha elingaphezulu elinombala, bese livala ifilimu noma ukucwebezela, bese lifaka iglu ngokuzenzela noma laminate ngokuzenzakalelayo ukubumba kukathayela; (2) Izithombe ezinemibala nemibhalo iphrintwa efilimini yepulasitiki, bese imbozwa ekhadini, bese kunamathiselwa bese kwenziwa.ibhokisi likashokoledi lika-valentine

Kungakhathaliseki ukuthi iyiphi inqubo esetshenziselwa ukukhiqiza amabhokisi ombala webhokisi lombala, ukucindezela kwawo okuthwalayo namandla okucindezela aphansi kakhulu kunamabhokisi e-watermark avamile ento efanayo (ekhiqizwe umugqa wekhadibhodi), futhi kunzima ukuqinisekisa ikhwalithi uma amakhasimende ephuthuma. isidingo noma ngezinsuku zemvula. Abakhiqizi abanezinkinga ezijulile, ngakho-ke bangaxazulula kanjani?ibhokisi likashokoledi ikhekhe

Wonke umuntu uyazi ukuthi amabhokisi akhiqizwa umugqa wekhadibhodi akhiwa ngokufaka i-glue, ukushisa ukuze kuhlanganiswe ngokushesha, nokomisa; kuyilapho ibhokisi lombala webhokisi lombala we-laminated ikhadibhodi lingashisi futhi lomisiwe, futhi umswakama ku-glue ungena ephepheni. Ngokuhambisana nesithiyo se-varnish ebusweni obunemibala kanye nefilimu yepulasitiki, umswakama osebhokisini elingenalutho awukwazi ukuchithwa isikhathi eside, futhi uzothambisa ngokwemvelo futhi unciphise amandla awo. Ngakho-ke, sibheka isixazululo senkinga kulezi zici ezilandelayo:ibhokisi likashokoledi lesipho

⒈ ukuqoqwa kwephepha amabhokisi kashokoledi okunethezeka

Amanye amabhizinisi anokungaqondi kahle okunjalo: isisindo esikhulu sephepha ngaphakathi, ingcindezi yokuthwala kanye namandla okucindezela ebhokisi azokwanda, kodwa akunjalo. Ukuze kuthuthukiswe ingcindezi yokuthwala namandla acindezelayo webhokisi lombala webhokisi lombala, umthamo wokuthwala ingcindezi wephepha eliwumgogodla kufanele uthuthukiswe. Uma nje iphepha elingaphezulu lingabonakali imikhondo eboshiwe ngemva kokunamathiselwa, iphepha elinesisindo esincane kufanele lisetshenziswe ngangokunokwenzeka; i-core paper kanye ne-tile paper isetshenziswa kangcono. I-pulp yotshani noma i-wood pulp paper enamandla amahle namandla okucindezela indandatho ephezulu. Ungasebenzisi iphepha likathayela lamandla aphakathi nendawo noma lamandla ajwayelekile, ngoba ngokuvamile liyingxube ye-pulp eluhlaza kanye ne-pulp egaywe kabusha, emunca amanzi ngokushesha, amandla okucindezela indandatho ephansi, nokuqina okuhle kodwa ukuqina okuphansi. Ngokusho kokuhlolwa, izinga lokumuncwa kwamanzi ephepha likathayela lamandla aphakathi liyi-15% -30% ephakeme kunaleyo yephepha eligxotshiwe elilinganiswa ngendlela ye-Kebo; isisindo sephepha le-lining singandiswa ngendlela efanele. Ukuzijwayeza kufakazele ukuthi ukunciphisa uhlelo lolimi lwephepha elingaphakathi kanye nokwandisa uhlelo lwephepha likathayela kanye nephepha eliwumgogodla kunezinzuzo ezincintisana kakhulu ngokwekhwalithi namanani.ibhokisi lesipho likashokoledi

⒉Ikhwalithi yeglueamabhokisi esipho sikashokoledi

Iningi lokukhiqizwa kwebhokisi manje lisebenzisa i-cornstarch glue eyenziwe ekhaya noma ethengiwe. Iglue yommbila yekhwalithi ephezulu ayinawo amandla amahle okubopha, kodwa futhi ingathuthukisa ingcindezi yokuthwala nokuqina kwekhadibhodi, futhi umzimba webhokisi akulula ukuwohloka. Izinga leglue lesitashi lommbila lihlobene eduze nenqubo yokukhiqiza, imvelo, ikhwalithi yezinto ezingavuthiwe neziyisizayo, nesikhathi sokuxuba. Izimfuneko zekhwalithi ze-cornstarch, fineness 98-100 mesh, okuqukethwe komlotha okungadluli ku-0.1%; okuqukethwe kwamanzi 14.0%; i-acidity engu-20CC/100g; sulphur dioxide 0.004%; iphunga elivamile; mhlophe noma phuzi kancane ngombala.ibhokisi elincane likashokoledi

Uma izinga lesitashi se-gelatinized lingahlangabezani naleli zinga, isilinganiso samanzi singancishiswa ngokufanele kuye ngokuthi isimo. Njengoba izinga lokushisa likhuphuka, isilinganiso samanzi kufanele sincishiswe ngokufanele, i-borax ne-caustic soda kufanele inyuswe ngokufanelekile, futhi inani le-hydrogen peroxide kufanele lincishiswe. I-glue ephekiwe akufanele igcinwe isikhathi eside, ikakhulukazi ehlobo, kungcono ukuyisebenzisa njengoba wenza. Ukwengeza i-3% -4% ye-formaldehyde, i-0.1% ye-glycerin ne-0.1% ye-boric acid ku-glue ingakhuphula ukumelana namanzi kwephepha, isheshise isivinini sokubopha, futhi iqinise amakhadibhodi. ubulukhuni.isipho chocolate box

Ngaphezu kwalokho, i-glue yamakhemikhali enobungani bemvelo, okungukuthi, i-PVA yokunamathisela, ingasetshenziswa futhi lapho kufakwa ibhodi lephepha. Izici zayo ukuthi ikhadibhodi likathayela elamiwe liyisicaba, liqondile, liboshwe kahle, futhi liqinile ngaphandle kokuguqulwa. Indlela yokukhiqiza (kuthatha i-100kg yokunamathisela njengesibonelo): isilinganiso sezinto ezibonakalayo: i-polyvinyl alcohol 13.7kg, i-polyvinyl acetate emulsion 2.74kg, i-oxalic acid 1.37kg, amanzi 82kg, isilinganiso samanzi 1: 6). Okokuqala, ukushisa amanzi ku-90 ° C, engeza i-polyethylene glycol bese ugoqa ngokulinganayo, qhubeka ushisa kuze kube yilapho amanzi ebila, fudumala amahora angu-3, ​​bese ufaka i-oxalic acid bese uvuselela, ekugcineni ungeze i-polyvinyl acetate emulsion bese uvuselela ngokulinganayo.

⒊ Inani leglue

Kungakhathaliseki ukuthi ukufakwa ngesandla noma okuzenzakalelayo komshini wezindawo ezinemibala, inani leglue elisetshenzisiwe akufanele libe likhulu kakhulu. Ekukhiqizeni kwangempela, abanye abasebenzi bakhuphula ngokungemthetho inani leglue elisetshenziswayo ukuze kugwenywe ukukhishwa kwe-degumming, okungafaneleki futhi kufanele kulawulwe ngokuqinile. Inani leglue elisetshenzisiwe kufanele libe ngu-80-110g/m2. Kodwa-ke, kuye ngobukhulu be-corrugated corrugated, kuhle ukubamba inani leglue futhi ugqoke ngokulinganayo iziqongo ze-corrugated. Uma nje ingekho i-degumming, inani elincane leglue, lingcono.

⒋Ikhwalithi yekhadibhodi yohlangothi olulodwaukulethwa kwebhokisi likashokoledi

Izinga lekhadibhodi likathayela elinohlangothi olulodwa linqunywa ikhwalithi yephepha lesisekelo, uhlobo lukathayela, izinga lokushisa elisebenzayo lomshini kathayela, ikhwalithi yokunamathisela, ijubane lokugijima lomshini, kanye nezinga lobuchwepheshe opharetha.
