Umehluko phakathi kwephepha elimhlophe lebhodi kanye nekhadibhodi elimhlophe ibhokisi lekhekhe

Iphepha lebhodi elimhlophe liwuhlobo lwekhadibhodi elinobuso obumhlophe nobubushelelezi kanye nesizinda esimpunga ngemuvaibhokisi likashokolediLolu hlobo lwekhadibhodi lusetshenziswa kakhulu ekuphrinteni ngombala ohlangothini olulodwa ukwenza amabhokisi okupakisha. Usayizi wephepha lebhodi elimhlophe lingu-787mm*1092mm, noma ezinye izici noma iphepha eligoqekayo lingakhiqizwa ngokwesivumelwano se-oda. Ngenxa yokuthi isakhiwo sefayibha sephepha lebhodi elimhlophe sifana kakhulu, ungqimba olungaphezulu lunezingxenye zokugcwalisa kanye nerabha, futhi ubuso bumbozwe ngopende othile, futhi bucutshungulwe nge-multi-roller calendering, ngakho-ke ukuthungwa kwebhodi kuqinile impela, futhi ubukhulu bufana kakhulu. Zonke izimo zimhlophe futhi zibushelelezi, ngokumuncwa kweyinki okufanayo, uthuli oluncane kanye nokulahlekelwa izinwele ebusweni, ikhwalithi yephepha eqinile kanye nokumelana okungcono kokugoqeka, kodwa okuqukethwe kwamanzi kuphakeme, ngokuvamile ku-10%, kunezinga elithile lokuguquguquka, okuzoba nomthelela othile ekuphrinteni. Umehluko phakathi kwephepha lebhodi elimhlophe nephepha elimboziwe, iphepha elingaphandle, nephepha le-letterpress ukuthi iphepha lisinda futhi iphepha liqinile impela.ukupakishwa kwesipho sephepha

Iphepha lebhodi elimhlophe lenziwe nge-pulp ephezulu kanye nesendlalelo ngasinye se-pulp engezansi emshinini wephepha owomisa ngemigqomo eminingi noma emshinini webhodi elihlanganisiwe elinetha eliyindilinga. I-pulp ngokuvamile ihlukaniswe nge-surface pulp (ungqimba olungaphezulu), ungqimba lwesibili, ungqimba lwesithathu, kanye nesendlalelo sesine. Isilinganiso se-fiber sesendlalelo ngasinye se-pulp yephepha sihlukile, futhi isilinganiso se-fiber sesendlalelo ngasinye se-pulp sincike enkambisweni yokwenza iphepha. Ikhwalithi iyahlukahluka. Isendlalelo sokuqala yi-surface pulp, edinga ubumhlophe obukhulu namandla athile. Ngokuvamile, kusetshenziswa i-bleached kraft wood pulp noma i-chemical straw pulp kanye ne-white paper edge waste paper pulp; ungqimba lwesibili yi-lining layer, esebenza njengendawo yokuhlukaniswa. Indima yesendlalelo esiyinhloko kanye nesendlalelo esiyinhloko nayo idinga izinga elithile lobumhlophe, ngokuvamile nge-100% mechanical wood pulp noma i-waste paper pulp enombala okhanyayo; ungqimba lwesithathu yi-core layer, esebenza kakhulu njengokugcwalisa ukwandisa ukujiya kwekhadibhodi nokuthuthukisa ukuqina. Kusetshenziswa i-mixed waste paper pulp noma i-straw pulp. Lolu ngqimba luwugqinsi kakhulu, futhi ikhadibhodi elinesisindo esikhulu livame ukusetshenziselwa ukulengisa i-pulp izikhathi eziningana ezindaweni eziningana ze-mesh; Isendlalelo esilandelayo ungqimba olungezansi, olunemisebenzi yokuthuthukisa ukubukeka kwekhadibhodi, ukwandisa amandla alo, nokuvimbela ukugoba. I-pulp ekhiqiza kakhulu noma i-pulp yephepha elilahliwe elingcono isetshenziswa njengezinto zokusetshenziswa zokwenza iphepha. Ingxenye engezansi yekhadibhodi ikakhulukazi ingwevu, kanti eminye imibala engezansi nayo ingakhiqizwa ngokwezidingo.ibhokisi lobucwebe

Ikhadibhodi elimhlophe lisetshenziselwa ukuphrinta amakhadi ebhizinisi, izembozo, izitifiketi, izimemo kanye nokupakishwa. Ikhadibhodi elimhlophe liyiphepha eliyisicaba, futhi ubukhulu balo obuyinhloko yilo: 880mm*1230mm, 787mm*1032mm. Ngokwezinga lekhwalithi, ikhadibhodi elimhlophe lihlukaniswe ngamagreyidi amathathu: a, B, kanye no-C. Ikhadibhodi elimhlophe likhulu futhi liqinile, linesisindo esikhulu sesisekelo, futhi isisindo salo sesisekelo sinemininingwane ehlukahlukene efana no-200 g/m2, 220 g/m2, 250 g/m2, 270 g/m2, 300 g/m2, 400 g/m2 njalo njalo. Ukuqina kwekhadibhodi elimhlophe ngokuvamile akungaphansi kuka-0.80 g/m3, futhi izidingo zobumhlophe ziphakeme kakhulu. Ubumhlophe bamagreyidi a, B, kanye no-C abungaphansi kuka-92.0%, 87.0%, kanye no-82.0%, ngokulandelana. Ukuze kuvinjelwe ukubhukuda, ikhadibhodi elimhlophe lidinga izinga lobukhulu elikhulu, kanti amazinga osayizi ka-a, B, no-C awangaphansi kuka-1.5mm, 1.5mm, kanye no-1.0mm ngokulandelana. Ukuze kugcinwe ukushelela kwemikhiqizo yamaphepha, ikhadibhodi elimhlophe kufanele libe likhulu futhi liqine, libe nokuqina okuphezulu namandla aqhumayo. Kunezidingo ezahlukene zokuqina kwamakhadibhodi amhlophe anezinga nezisindo ezahlukene. Uma isisindo sikhulu, izinga liphakeme, futhi ukuqina kuphakeme. Uma isidingo sokuqina sikhulu, ukuqina okujwayelekile kobude akufanele kube ngaphansi kuka-2.10-10.6mN•m, kanti ukuqina okuphambene akufanele kube ngaphansi kuka-1.06-5.30 mN•m.ibhokisi likashokoledi
