Umahluko phakathi kwephepha lebhodi elimhlophe kunye nekhadibhodi emhlophe ibhokisi yekhekhe

Iphepha lebhodi elimhlophe luhlobo lwekhadibhodi elinomphambili omhlophe nogudileyo kunye nemvelaphi engwevu ngasemvaibhokisi yetshokholethiOlu hlobo lwekhadibhodi lusetyenziswa kakhulu ekuprinteni imibala emacala omabini ukwenza iibhokisi zokupakisha. Ubungakanani bephepha lebhodi emhlophe yi-787mm*1092mm, okanye ezinye iinkcukacha okanye iphepha eliqengqelekayo linokwenziwa ngokwesivumelwano soku-odola. Ngenxa yokuba ulwakhiwo lwefayibha yephepha lebhodi emhlophe lufana kakhulu, umaleko womphezulu unezinto zokuzalisa kunye nerabha, kwaye umphezulu ugqunywe ngobungakanani obuthile bepeyinti, kwaye ucutshungulwe nge-multi-roller calendering, ngoko ke ubume bebhodi buqinile, kwaye ubukhulu bufana kakhulu. Zonke iimeko zimhlophe kwaye zithambile, zine-inki efanayo, uthuli oluncinci kunye nokulahleka kweenwele kumphezulu, umgangatho wephepha onamandla kunye nokumelana okungcono kokugoba, kodwa umxholo wamanzi uphezulu, ngokubanzi kwi-10%, kukho inqanaba elithile lokuguquguquka, eliya kuba nefuthe elithile ekuprinteni. Umahluko phakathi kwephepha lebhodi emhlophe kunye nephepha eligqunywe nge-coated, iphepha elingaphandle, kunye nephepha le-letterpress kukuba iphepha linzima kwaye iphepha lixinene kakhulu.ukupakishwa kwesipho sephepha

Iphepha lebhodi elimhlophe lenziwe nge-pulp ephezulu kunye nomaleko ngamnye we-pulp esezantsi kumatshini wephepha owomisayo onemigqomo emininzi okanye umatshini webhodi oxutyiweyo one-oval net. I-pulp ngokubanzi yahlulwe yaba yi-surface pulp (umaleko womphezulu), umaleko wesibini, umaleko wesithathu, kunye nomaleko wesine. Umlinganiselo wefayibha womaleko ngamnye we-pulp yephepha wahlukile, kwaye umlinganiselo wefayibha womaleko ngamnye we-pulp uxhomekeke kwinkqubo yokwenza iphepha. Umgangatho uyahluka. Umaleko wokuqala yi-surface pulp, efuna ubumhlophe obuphezulu kunye namandla athile. Ngokwesiqhelo, kusetyenziswa i-bleached kraft wood pulp okanye i-bleached chemical straw pulp kunye ne-white paper edge waste paper pulp; umaleko wesibini ngumaleko we-lining, osebenza njengomphezulu wokwahlukanisa. Indima yomaleko oyintloko kunye nomaleko oyintloko ikwafuna inqanaba elithile lobumhlophe, ngesiqhelo nge-100% ye-mechanical wood pulp okanye i-waste paper pulp enemibala ekhanyayo; umaleko wesithathu ngumaleko oyintloko, osebenza ngokuyintloko njengokuzalisa ukwandisa ubukhulu bekhadibhodi kunye nokuphucula ukuqina. Kusetyenziswa i-mixed waste paper pulp okanye i-straw pulp. Olu maleko lolona lukhulu, kwaye ikhadibhodi enobunzima obuphezulu idla ngokusetyenziswa ukuxhoma i-pulp izihlandlo ezininzi kwiindawo ezininzi ze-mesh; Umaleko olandelayo ngumaleko ongezantsi, onemisebenzi yokuphucula inkangeleko yekhadibhodi, ukwandisa amandla ayo, kunye nokuthintela ukugoba. I-pulp evelisa kakhulu okanye i-pulp yephepha elilahliweyo engcono isetyenziswa njengezinto zokwenza iphepha. Umphezulu osezantsi wekhadibhodi uninzi lwawo lungwevu, kwaye eminye imibala esezantsi nayo inokuveliswa ngokweemfuno.ibhokisi yobucwebe

Ikhadibhodi emhlophe isetyenziselwa ukuprinta amakhadi eshishini, izigqubuthelo, izatifikethi, izimemo kunye nokupakishwa. Ikhadibhodi emhlophe liphepha elithe tyaba, kwaye ubukhulu bayo obuphambili buyi: 880mm*1230mm, 787mm*1032mm. Ngokwenqanaba lomgangatho, ikhadibhodi emhlophe yahlulwe yangamanqanaba amathathu: a, B, kunye no-C. Ikhadibhodi emhlophe ityebile kwaye iqinile, inobunzima obukhulu besiseko, kwaye ubunzima bayo besiseko buneenkcazo ezahlukeneyo ezifana ne-200 g/m2, 220 g/m2, 250 g/m2, 270 g/m2, 300 g/m2, 400 g/m2 njalo njalo. Ukuqina kwekhadibhodi emhlophe kudla ngokuba ngaphantsi kwe-0.80 g/m3, kwaye iimfuno zobumhlophe ziphezulu. Ubumhlophe bamanqanaba e-a, B, kunye ne-C abungaphantsi kwe-92.0%, 87.0%, kunye ne-82.0%, ngokwahlukeneyo. Ukuze kuthintelwe ukudada, ikhadibhodi emhlophe ifuna ubungakanani obukhulu, kwaye ubungakanani obufana no-a, B, kunye no-C abufanele bube ngaphantsi kwe-1.5mm, 1.5mm, kunye ne-1.0mm ngokulandelelana. Ukuze kugcinwe ukuguda kweemveliso zephepha, ikhadibhodi emhlophe kufuneka ibe nkulu kwaye iqine, ibe nokuqina okuphezulu kunye namandla aqhumayo. Kukho iimfuno ezahlukeneyo zokuqina kwekhadibhodi emhlophe yeendidi ezahlukeneyo kunye nobunzima. Okukhona ubunzima bukhulu, kokukhona ubunzima buphezulu, kwaye kokukhona ubunzima buphezulu. Okukhona ubunzima bukhulu, ukuqina okuqhelekileyo kobude akufuneki kube ngaphantsi kwe-2.10-10.6mN•m, kwaye ukuqina okunqamlezileyo akufuneki kube ngaphantsi kwe-1.06-5.30 mN•m.ibhokisi yetshokholethi
