Muva nje, imijikelezo eminingi yamagagasi abandayo ihlasele kaningi ukusuka enyakatho kuya eningizimu. Izingxenye eziningi zomhlaba ziye zaba nokupholisa ngendlela ye-bungee, futhi ezinye izindawo zithole ngisho nomzuliswano wazo wokuqala wokukhithika. Kulesi simo sezulu esishisayo, ngaphezu kohambo lwansuku zonke lwawo wonke umuntu, ukukhiqizwa kwezinkampani zokupakisha nokunyathelisa nakho kuye kwathinteka ngezinga elithile.
Ngakho, ebhekene nesimo sezulu esinjalo esinzima, yimiphi imininingwane okufaneleukupakishaabaphrinta banake?
Ivimbela ama-inki we-web offset ukuthi angaqini lapho kubanda
Kuyinki, uma izinga lokushisa legumbi kanye nezinga lokushisa likayinki lishintshile, isimo sokugeleza kweyinki sizoshintsha, futhi umbala uzoshintsha ngokufanele. Ngesikhathi esifanayo, isimo sezulu esiphansi sokushisa sizoba nomthelela omkhulu kuzinga lokudlulisa uyinki lendawo yokukhanya okuphezulu. Ngakho-ke, lapho unyathelisa imikhiqizo yezinga eliphezulu, izinga lokushisa kanye nomswakama we-workshop yokunyathelisa kufanele ilawulwe kunoma yikuphi. Ngaphezu kwalokho,ukusetshenziswa kukayinki ebusika kufanele kushise kusengaphambili, ukuze kuncishiswe ukushintsha kwezinga lokushisa kukayinki ngokwawo.
Qaphela ukuthi uyinki ugqinsile kakhulu futhi i-viscosity inkulu, kodwa kungcono ukungasebenzisi umncane noma uyinki ukulungisa i-viscosity yawo. Ngoba uma umsebenzisi edinga ukuxuba uyinki, uyinki ifektri ekhiqizwa uyinki eluhlaza kungaba ukuhlalisa inani eliphelele izithasiselo kunqunyelwe, ngale komkhawulo, ngisho noma ingasetshenziswa, futhi buthaka ukusebenza okuyisisekelo uyinki, kuthinte izinga lokunyathelisa ubuchwepheshe zokunyathelisa.
Naka ukusetshenziswa kwe-anti-freeze UV varnish
I-varnish ye-UV nayo iyinto ethinteka kalula ngamazinga okushisa aphansi. Ngakho-ke, abahlinzeki abaningi basebenza ngokukhethekile ekukhiqizeni amafomula amabili ahlukene, uhlobo lwasebusika kanye nohlobo lwasehlobo. Ifomula yasebusika inokuqukethwe okuqinile okuphansi kunefomula yasehlobo,okungenza ukusebenza kokulinganisa kwe-varnish kube ngcono lapho izinga lokushisa liphansi.
Qaphela ukuthi uma usebenzisa ifomula yasebusika ehlobo, izokwenza kalula ukuthi uwoyela ungalapheki ngokuphelele futhi ungaholela ekunamatheleni emuva. Ngokuphambene nalokho, uma usebenzisa ifomula yasehlobo ebusika, izodala ukusebenza kabi kwezinga likawoyela we-UV, okubangele izinkinga zamabhamuza kanye nesikhumba esolintshi.
Umphumela wesimo sezulu esibandayo ephepheni
In ukukhiqizwa kokunyathelisa, iphepha lingenye yezinto ezisetshenziswayo ezinezidingo eziphezulu zokushisa kwemvelo kanye nomswakama. Iphepha liyi-porous material, futhi isakhiwo salo esiyisisekelo sakhiwe imicu yezitshalo kanye nezinsiza, ezinezakhiwo eziqinile ze-hydrophilic. Uma izinga lokushisa lemvelo kanye nomswakama kungalawulwa kahle, kuzoholela ekuguqulweni kwephepha futhi kuthinte ukuphrinta okuvamile. Ngakho-ke, ukugcina izinga lokushisa elifanele lemvelo kanye nomswakama kuyisihluthulelo sokuthuthukisa ikhwalithi yemikhiqizo yokuphrinta iphepha nokuthuthukisa ukusebenza kahle kokukhiqiza.
Iphepha elijwayelekile lezidingo zokushisa kwemvelo alibonakali kangako,kodwa lapho izinga lokushisa lemvelo lingaphansi kuka-10 ℃, iphepha elivamile lizoba "brittle" kakhulu, ukunamathela koqweqwe lukayinki ebusweni bayo kuzokwehla., kulula ukubangela i-deinking phenomenon.
Iphepha lekhadi legolide nesiliva ngokuvamile lenziwa ngephepha elimboziwe, iphepha lebhodi elimhlophe, iphepha lekhadi elimhlophe njengesisekelo, bese lihlanganiswa.Ifilimu ye-PETnoma i-aluminium foil nezinye izinto ezikhiqizwayo. Iphepha lekhadi legolide nesiliva ezinye izidingo eziphakeme zokushisa kwemvelo, lokhu kungenxa yokuthi impahla yensimbi nepulasitiki izwela kakhulu ekushintsheni kwezinga lokushisa,lapho izinga lokushisa lemvelo lingaphansi kuka-10 ℃, lizothinta kakhulu ukufaneleka kwephepha legolide nesiliva lekhadi legolide, lapho izinga lokushisa lemvelo lendawo yokugcinwa kwephepha legolide nelesiliva lizungeze u-0 ℃, kusukela endaweni yokusebenzela yokunyathelisa, indawo engaphezulu izoba ngumswakama omningi wamanzi. ,kuthinte ukuphrinta okuvamile, kungaholela ngisho nasekumosheni. Uma kuhlangatshezwana nezinkinga ezingenhla, futhi isikhathi sokulethwa siqinile, izisebenzi zingaqala ngokuvula ishubhu lesibani le-UV ukuze iphepha liphinde lisebenze lingenalutho, ukuze izinga lokushisa nebhalansi yezinga lokushisa elizungezile ngaphambi kokuphrinta okusemthethweni.
Ngaphezu kwalokho,izinga lokushisa eliphansi omiswe, umswakama ongaphakeme isihlobo, iphepha kanye air umswakama exchange, iphepha iba omile, babe esonta, ukusikwa, kuzodala overprinting abampofu.
Umphumela wokushisa okuphansi ku-adhesive glue
I-Adhesive iyilungiselelo elibalulekile lamakhemikhali ekukhiqizeni izimboni namuhla. Ukusebenza kwe-adhesive kuthinta ngqo ikhwalithi yemikhiqizo yezimboni. Inkomba yezobuchwepheshe ebalulekile ekukhiqizeni okunamathelayo ukulawula izinga lokushisa. Iningi lezinto zokusetshenziswa kwe-adhesives ziyi-polymers ephilayo, enezinga eliphezulu lokuncika kokushisa, okusho ukuthi izakhiwo zabo zemishini kanye ne-viscoelasticity ziyathinteka ngokushintsha kwezinga lokushisa. Kufanele kuphawulwe ukuthiizinga lokushisa eliphansi liyicala eliyinhloko lokunamathela kwamanga kweglue.
Lapho izinga lokushisa lehla, ubulukhuni be-adhesive buba nzima, futhi ukucindezeleka ekunamatheleni kuyashintshwa.Esimweni sokushisa esiphansi esiphambene, ukunyakaza kwe-polymer chain ku-adhesive kunqunyelwe, kunciphisa ukuqina kokunamathela.
