Ungayandisa kanjani ingcindezi yokuthwala kanye namandla okucindezela amabhokisi ombala wephepha elihlanganisiwe? 

Njengamanje, izinkampani eziningi zokupakisha ezweni lakithi zisebenzisa izinqubo ezimbili ukukhiqiza amabhokisi ombala: (1) kuqala phrinta iphepha elinombala, bese umboza ifilimu noma i-glazing, bese ufaka i-glue ngesandla noma unamathisele ngokuzenzakalelayo ukwakheka okuhlanganisiwe; (2) Izithombe nemibhalo enemibala kuphrintwa efilimini yepulasitiki, bese kuvalwa ekhadibhodini, bese kunamathiselwa futhi kwakhiwe.ibhokisi leshokoledi likaValentine

Kungakhathaliseki ukuthi iyiphi inqubo esetshenziswayo ukukhiqiza amabhokisi ombala webhokisi lombala, ingcindezi yayo yokuthwala kanye namandla okucindezela kuphansi kakhulu kunamabhokisi ajwayelekile e-watermark enziwe ngezinto ezifanayo (ezikhiqizwa umugqa wekhadibhodi), futhi kunzima ukuqinisekisa ikhwalithi uma amakhasimende eswele kakhulu noma ezinsukwini zemvula. Abakhiqizi abanenkinga enkulu, ngakho-ke bangaxazulula kanjani?ikhekhe letshokolethi lebhokisi

Wonke umuntu uyazi ukuthi amabhokisi akhiqizwa umugqa wekhadibhodi akhiwa ngokufaka iglue, ukushisa ukuze kuhlanganiswe ngokushesha, nokomisa; kuyilapho ibhokisi lebhokisi lemibala elinolaminated lingashisi futhi lomiswe, futhi umswakama oseglue ungena ephepheni. Uma kuhambisana nesithiyo se-varnish ebusweni obunombala kanye nefilimu yepulasitiki, umswakama osebhokisini elingenalutho awukwazi ukunyamalala isikhathi eside, futhi uzothamba ngokwemvelo futhi unciphise amandla awo. Ngakho-ke, sifuna ikhambi lenkinga kulezi zinto ezilandelayo:ibhokisi likashokoledi lesipho

⒈ ukuhlanganiswa kwephepha amabhokisi kashokholethi okunethezeka

Amanye amabhizinisi anokungaqondi kahle okunjalo: lapho isisindo sephepha ngaphakathi sikhulu, kulapho ingcindezi yokuthwala kanye namandla okucindezela ebhokisi kuzokhushulwa khona, kodwa akunjalo. Ukuze kuthuthukiswe ingcindezi yokuthwala kanye namandla okucindezela ebhokisini lombala webhokisi lombala, amandla okuthwala ingcindezi ephepha eliyinhloko kumele athuthukiswe. Uma nje iphepha elingaphezulu lingabonakali imikhondo egobile ngemva kokunamatheliswa, iphepha elinesisindo esincane kufanele lisetshenziswe ngangokunokwenzeka; iphepha eliyinhloko kanye nephepha lethayela kungcono kakhulu ukusebenzisa. I-pulp yotshani noma iphepha le-pulp yokhuni elinamandla amahle kanye namandla aphezulu okucindezela indandatho. Ungasebenzisi iphepha eligobile elinamandla aphakathi noma ajwayelekile, ngoba ikakhulukazi liyingxube ye-pulp eluhlaza kanye ne-pulp ephinde yasetshenziswa, enokumuncwa kwamanzi okusheshayo, amandla aphansi okucindezela indandatho, kanye nokuqina okuhle kodwa ukuqina okuphansi. Ngokusho kokuhlolwa, izinga lokumuncwa kwamanzi ephepha eligobile elinamandla aphakathi liphakeme ngo-15%-30% kunelephepha eligobile elilinganiswa ngendlela ye-Kebo; isisindo sephepha elingaphakathi singakhushulwa ngokufanele. Umkhuba ubonise ukuthi ukunciphisa ubukhulu bephepha elingaphakathi nokwandisa ubukhulu bephepha elihlanganisiwe neliyinhloko kunezinzuzo ezincintisana kakhulu ngokwekhwalithi kanye nentengo.ibhokisi lesipho loshokoledi

⒉Ikhwalithi yeglueamabhokisi esipho kashokoledi

Iningi lemikhiqizo yebhokisi manje lisebenzisa iglue ye-cornstarch eyenziwe ekhaya noma ethengiwe. Iglue ye-corn esezingeni eliphezulu ayigcini nje ngokuba namandla amahle okubopha, kodwa futhi ingathuthukisa ingcindezi yokuthwala kanye nokuqina kwekhadibhodi, futhi umzimba webhokisi akulula ukuyiguqula. Ikhwalithi yeglue yesitashi se-corn ihlobene eduze nenqubo yokukhiqiza, indawo ezungezile, ikhwalithi yezinto zokusetshenziswa ezingavuthiwe nezisizayo, kanye nesikhathi sokuxuba. Izidingo zekhwalithi ye-cornstarch, ubuncane obungu-98-100 mesh, okuqukethwe komlotha okungadluli ku-0.1%; okuqukethwe kwamanzi okungu-14.0%; i-asidi engu-20CC/100g; i-sulfur dioxide engu-0.004%; iphunga elijwayelekile; umbala omhlophe noma ophuzi kancane.ibhokisi elincane letshokolethi

Uma ikhwalithi yesitashi esifakwe i-gelatinized ingahlangabezani naleli zinga, isilinganiso samanzi singancishiswa ngokufanele kuye ngesimo. Njengoba izinga lokushisa likhuphuka, isilinganiso samanzi kufanele sincishiswe ngokufanele, i-borax ne-caustic soda kufanele kwandiswe ngokufanele, futhi inani le-hydrogen peroxide kufanele lincishiswe. Iglue ephekiwe akufanele igcinwe isikhathi eside, ikakhulukazi ehlobo, kungcono ukuyisebenzisa njengoba uyenzayo. Ukwengeza i-formaldehyde engu-3%-4%, i-glycerin engu-0.1% kanye ne-boric acid engu-0.1% kuglue kungandisa ukumelana kwamanzi kwephepha, kusheshise isivinini sokubopha, futhi kuqinise ubulukhuni bekhadibhodi.ibhokisi lesipho letshokolethi

Ngaphezu kwalokho, iglue yamakhemikhali enobungani nemvelo, okungukuthi, inhlaka ye-PVA, ingasetshenziswa futhi lapho kugxunyekwa ibhodi lephepha. Izici zayo ukuthi ikhadibhodi elihlanganisiwe elihlanganisiwe liyisicaba, liqondile, liboshwe kahle, futhi lihlala isikhathi eside ngaphandle kokuguquka. Indlela yokukhiqiza (uma sithatha i-100kg yenhlaka 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, fudumeza amanzi ku-90°C, engeza i-polyethylene glycol bese uvuselela ngokulinganayo, qhubeka nokushisa kuze kube yilapho amanzi ebila, gcina ufudumele amahora ama-3, bese ufaka i-oxalic acid bese uvuselela, ekugcineni engeza i-polyvinyl acetate emulsion bese uvuselela ngokulinganayo.

⒊Inani leglue

Kungakhathaliseki ukuthi ukufakwa kwezindawo ezinemibala ngesandla noma ngokuzenzakalelayo, inani leglue elisetshenziswayo akufanele libe likhulu kakhulu. Ekukhiqizeni kwangempela, abanye abasebenzi bandisa ngokwenziwa inani leglue elisetshenziswayo ukuze bagweme ukukhipha i-gum, okungafanele futhi okumele kulawulwe ngokuqinile. Inani leglue elisetshenziswayo kufanele libe ngu-80-110g/m2. Kodwa-ke, kuye ngobukhulu beglue ehlanganisiwe, kungcono ukubamba inani leglue bese umboza ngokulinganayo iziqongo ezihlanganisiwe. Uma nje kungekho ukususa i-gum, inani leglue elincane, kungcono.

⒋Ikhwalithi yekhadibhodi elinohlangothi olulodwaukulethwa kwebhokisi leshokoledi

Ikhwalithi yekhadibhodi eligoqekile elinohlangothi olulodwa inqunywa yikhwalithi yephepha eliyisisekelo, uhlobo lwe-corrugation, izinga lokushisa lokusebenza komshini we-corrugating, ikhwalithi ye-glue, isivinini sokusebenza komshini, kanye nezinga lobuchwepheshe lomqhubi.
