Umehluko phakathi kwephepha lebhodi elimhlophe nekhadibhodi elimhlophe ibhokisi lekhekhe

Iphepha lebhodi elimhlophe liwuhlobo lwekhadibhodi elinengaphambili elimhlophe nelibushelelezi kanye nengemuva elimpunga ngemuvaibhokisi likashokoledi.Lolu hlobo lwekhadibhodi lusetshenziselwa ikakhulukazi ukuphrinta umbala ohlangothini olulodwa ukwenza amabhokisi okupakishwa.Usayizi wephepha lebhodi elimhlophe 787mm*1092mm, noma ezinye izicaciso noma iphepha lokugoqa lingakhiqizwa ngokuya ngenkontileka ye-oda.Ngenxa yokuthi isakhiwo se-fiber sephepha lebhodi elimhlophe siyafana, ungqimba olungaphezulu lunezingxenye zokugcwalisa kanye nenjoloba, futhi ubuso bumbozwe ngenani elithile lopende, futhi lucutshungulwe nge-multi-roller calendering, ngakho-ke ukuthungwa kwebhodi iqinile, futhi ukujiya kuyafana.Wonke amacala amhlophe futhi abushelelezi, anokumuncwa kweyinki afanayo, uthuli oluncane nokulahlekelwa izinwele ebusweni, ikhwalithi yephepha eliqinile nokumelana nokugoqa okungcono, kodwa okuqukethwe kwawo kwamanzi kuphakeme, ngokuvamile ku-10%, kunezinga elithile lokuguquguquka, okuzoba nomthelela othile ekunyatheliseni.Umehluko phakathi kwephepha le-whiteboard nephepha eliboshwe, iphepha le-offset, nephepha le-letterpress ukuthi iphepha linzima futhi iphepha liwugqinsi.iphepha-isipho-packaging

Iphepha lebhodi elimhlophe lenziwa nge-pulp ephezulu kanye nongqimba ngalunye lwe-pulp engezansi emshinini wephepha owusomisa kaningi wezigubhu noma umshini webhodi oxubile wenethi eliyisiyingi.I-pulp ngokuvamile ihlukaniswa nge-surface pulp (ungqimba olungaphezulu), ungqimba lwesibili, ungqimba lwesithathu, nolwesine.Isilinganiso se-fiber songqimba ngalunye lwe-pulp yephepha sihlukile, futhi isilinganiso se-fiber sengqimba ngayinye ye-pulp sincike kwinqubo yokwenza iphepha.Ikhwalithi iyahlukahluka.Isendlalelo sokuqala yi-pulp engaphezulu, edinga ubumhlophe obuphezulu namandla athile.Imvamisa, kusetshenziswa i-bleached kraft wood pulp noma i-bleached chemical straw pulp kanye ne-white edge waste paper pulp kusetshenziswa;ungqimba lwesibili ungqimba lwe-lining, olusebenza njengendawo yokuhlukanisa Indima yengqimba ewumgogodla kanye nesendlalelo esiwumgogodla nayo idinga izinga elithile lobumhlophe, ngokuvamile nge-100% yokhuni lwe-mechanical pulp noma imfucumfucu yephepha enemibala ekhanyayo;isendlalelo sesithathu yisingqimba esiyinhloko, esisebenza ngokuyinhloko njengokugcwalisa ukwandisa ubukhulu bekhadibhodi futhi kuthuthukise ukuqina.Kusetshenziswa i-mixed waste paper pulp noma i-straw pulp.Lolu ungqimba luwugqinsi kakhulu, futhi amakhadibhodi anesisindo esikhulu avame ukusetshenziselwa ukulenga i-pulp izikhathi eziningana ezindaweni ezinezikhala eziningana;ungqimba olulandelayo luyingqimba engezansi, enemisebenzi yokuthuthukisa ukubukeka kwekhadibhodi, ukwandisa amandla ayo, nokuvimbela ukugoqa.I-pulp enesivuno esiphezulu noma i-waste paper pulp engcono isetshenziswa njengempahla eluhlaza yokwenza iphepha.Indawo engezansi yekhadibhodi ngokuvamile impunga, kanti eminye imibala engezansi ingakhiqizwa ngokwezidingo.ibhokisi lobucwebe

Ikhadibhodi elimhlophe lisetshenziselwa ukuphrinta amakhadi ebhizinisi, amakhava, izitifiketi, izimemo nokupakisha.Ikhadibhodi elimhlophe yiphepha eliyisicaba, futhi ubukhulu balo obuyinhloko: 880mm*1230mm, 787mm*1032mm.Ngokwezinga lekhwalithi, ikhadibhodi elimhlophe lihlukaniswe ngamabanga amathathu: a, B, kanye no-C. Ikhadibhodi elimhlophe lishubile futhi liqina, linesisindo esiyisisekelo esikhulu, futhi isisindo salo esiyisisekelo sinezincazelo ezihlukahlukene ezifana ne-200 g/m2, 220. g/m2, 250 g/m2, 270 g/m2, 300 g/m2, 400 g/m2 nokunye.Ukuqina kwekhadibhodi elimhlophe ngokuvamile akubi ngaphansi kuka-0.80 g/m3, futhi izidingo zobumhlophe ziphakeme uma kuqhathaniswa.Ubumhlophe bamabanga a, B, no-C abukho ngaphansi kuka-92.0%, 87.0%, no-82.0%, ngokulandelana.Ukuze uvimbele ukubhukuda, amakhadibhodi amhlophe adinga idigri yokulinganisa enkulu, futhi amadigri osayizi ka-a, B, no-C awekho ngaphansi kuka-1.5mm, 1.5mm, no-1.0mm ngokulandelana.Ukuze kugcinwe ukushelela kwemikhiqizo yephepha, amakhadibhodi amhlophe kufanele abe mkhulu futhi aqine, abe nokuqina okuphezulu namandla aqhuma.Kunezidingo ezahlukene zokuqina kwamakhadibhodi amhlophe amabanga ahlukene nezisindo.Isisindo sikhulu, izinga eliphezulu, futhi ukuphakama kokuqina.Uma sikhulu isidingo sokuqina, ukuqina kwelongitudinal okuvamile akufanele kube ngaphansi kuka-2.10-10.6mN•m, futhi ukuqina okuphambene akufanele kube ngaphansi kuka-1.06-5.30 mN•m.ibhokisi likashokoledi
