Iphepha le-Kraft njengento evamile embonini yokunyathelisa nokupakisha, khona-ke uyazi ukuthi ungayisebenzisa kanjaniiphepha le-kraftkahle?
Ukusetshenziswa kwephepha le-kraft
Embonini yokunyathelisa nokupakisha, i-kraft paper ivame ukusetshenziselwa ukuphrinta izembozo zesitatimende sezimali, izimvilophu, ukupakishwa kwempahla, izikhwama zemibhalo, izikhwama zolwazi, izikhwama zezandla, amabhokisi amafayela, izikhwama zamafayela, njll.
Ukucaciswa kwephepha le-kraft
Okuvame ukusetshenziswaiphepha le-kraftinokucaciswa okuhlukahlukene okufana no-60g/m2, 70g/m2, 80g/m2, 100g/m2, 120g/m2, 150g/m2 ngisho no-250~450g/m2.
Izici ze-kraft paper
Izinzuzo:Iphepha le-Kraft linezinzuzo zokuqina okuhle, ukuthungwa okuqinile nokuqinile, okungadabuki kalula futhi kuphukile, futhi ukumelana nokuguga.
Ububi:i-kraft paper surface roughness, kulula ukuvela ku-buckle ngaphansi kwepiki, izinwele eziwayo, i-powder phenomenon, ubumhlophe, flatness, ukushelela akulungile.
Ukusetshenziswa kwamakhono e-kraft paper
① Ukulenga nokulungisa ukwelashwa okumanzi: isinyathelo sokuqala sokungalingani kwendawo futhi sisusiwe iphepha eliphukile, isinyathelo sesibili kuzoba ukungcola kwephepha, ukuhlanza umlotha wephepha, ukwelashwa okomisa okulenga, ukuze izinga lokushisa nomswakama we-kraft paper kanye ne-offset. lokushisa workshop yokunyathelisa kanye nomswakama ukuze silondoloze ukungaguquguquki.Iphepha le-Kraftngemva kokulenga omiswe ukwelashwa umswakama, ibekwe phezu isitaki iphepha sicindezelwe umxhaka wephepha, ngamatshe amakhulu, iron plate compaction, ukugwema iphepha Fluffy hhayi okuqinile.Ukwenza kanjalo kungagwema ngokuphumelelayo ukuvela kwephepha le-kraft ngenxa yokuqukethwe komswakama ongalingani kuvela kumcimbi wokubopha ngaphansi kwepiki.
② khetha imodeli enhle: ngenxa yephepha le-kraft elingu-80g/m2 elijiyile, emlonyeni wokulethwa kwephepha ngokuvamile alikwazi ukumunca iphepha, ngakho-ke lapho ukushuba kwephepha le-kraft ≥ 80g/m, kungcono ukungasebenzisi okuncane okuvulekile okune noma okuyisishiyagalombili. umshini wokuphrinta we-offset.Ngaphezu kwalokho, ngenxa yobubanzi bephepha elincane, kulula ukuphinda kabili noma ukwehluleka kwamashidi amaningi, noma iphepha elitshekile ekulethweni kwebhodi lephepha.Futhi ngomshini wokunyathelisa we-folio offset noma umshini wokunyathelisa ovula ngokugcwele we-offset ≥ 80g/m wephepha le-kraft, umphumela uzoba ngcono.
③ lungisa uhlelo lokulethwa kwephepha lomshini wokuphrinta we-offset: ubukhulu bephepha bukhulu kulula ukubangela izingozi zokumisa, ngakho-ke ngaphambi kokuqala umshini wokunyathelisa kufanele ube ngaphambi kokulawula i-punch, control skew, control double, namanye amadivaysi kagesi ukulungisa ezifanele, ukuvimbela iphepha kraft ezingaphezu kweyodwa roll umshini omubi.Kufanele ilungiswe kusayizi wevolumu yokumunca umlomo wombhobho wokumunca, umlomo wombhobho wokumunca iphepha kanye nombhobho wokumunca wephepha ukuze kusetshenziswe ububanzi kanye nogqinsi yiringi yerabha enkulu.
④ gcina ibanga lesikhungo sokuphrinta nesilinda senjoloba lingashintshiwe: lungisa ibanga eliphakathi lesilinda esibonakalayo nesilinda senjoloba futhi ugcine ibanga eliphakathi nendawo lingashintshiwe, lapho uphrinta iphepha le-kraft elingu-250 ~ 450g / m, leli banga eliphakathi lingakhuliswa ngo-0.2 ~ 0.4 mm.i-kraft paper surface roughness, ukushelela akulungile, ukuqina kwephepha kuncane kakhulu kunephepha le-copperplate, iphepha le-offset, ngakho-ke, ukuphrinta iphepha le-kraft, kodwa futhi ngokuhambisanayo kwandisa ingcindezi yokunyathelisa.Lapho uphrintaiphepha le-kraftukujiya ≥ 400g / m, isilinda ipuleti yokunyathelisa kanye igebe isilinda iraba 3.95mm, isilinda iraba futhi umbono cylinder igebe ukulungiswa for 3.40mm, isamba iphakethe ulwelwesi isilinda ipuleti lokuphrinta 0.65 ~ 0.75mm, isamba iphakethe ulwelwesi isilinda iraba for 3.15 ~ 3.35mm.Uma iphepha lokunyathelisa lisuka eliwugqinsi liye elincanyana, kufanele lidonswe kucwecwe lwepuleti lokunyathelisa endaweni yogqinsi oluncishisiwe lwe-Package lining, kanye nolwelwesi lwephakeji yesilinda senjoloba;uma iphepha lisuka elincanyana liye eliwugqinsi, kufanele lidonswe kusilinda senjoloba ukuze kwandiswe ukushuba komugqa wephakeji, kanye nolwelwesi lwephakeji yesilinda sepuleti lokuphrinta.
⑤ i-kraft paper surface rough, looxe, kulula ukuba yimpushana, izinwele, ngakho-ke lapho unyathelisa ukukhuhla ngenkuthalo isilinda senjoloba nesilinda sepuleti lokuphrinta, ukugwema izinwele zephepha, impushana yephepha enamathela kusilinda senjoloba nesilinda sepuleti lokuphrinta futhi kuthinte ukudluliswa kweyinki, okuholela ezithombeni ezisuka epuletini, ukuntuleka komugqa ophukile wepeni.Uma kuhlangatshezwana nayo ehlobo lapho ukunyathelisa kwe-monochrome, izinwele ze-kraft ze-kraft, izinkinga ezinkulu ze-powder zinganyatheliswa ngaphambi kongqimba olumbozekile lwamanzi, olunganciphisa ngempumelelo izinwele zephepha, i-powder phenomenon, ukuze iphepha libe ngaphezulu.
