Izinto ezivamile zokupakisha iphepha

Ngokuvamile, izinto ezivamile zokupakisha iphepha zihlanganisa iphepha likathayela, iphepha lekhadibhodi, iphepha lebhodi elimhlophe, amakhadibhodi amhlophe, amakhadibhodi egolide nesiliva, njll. Izinhlobo ezahlukene zephepha zisetshenziswa emikhakheni ehlukene ngokwezidingo ezahlukene, ukuze kuthuthukiswe imikhiqizo.Imiphumela yokuzivikela.

iphepha likathayela

Ngokohlobo lomtshingo, iphepha likathayela lingahlukaniswa ngezigaba eziyisikhombisa: Umgodi, umgodi B, umgodi ongu-C, umgodi ongu-D, u-E, u-F no-G.Phakathi kwayo, imigodi engu-A, B, no-C ivame ukusetshenziselwa ukupakisha kwangaphandle, kanti imigodi engu-D, E Ivamise ukusetshenziselwa ukupakisha okuncane nokuphakathi.

Iphepha elifakwe uthayela linezinzuzo zokukhanya nokuqina, ukumelana nomthwalo oqinile nokucindezela, ukumelana nokushaqeka, ukumelana nomswakama, nezindleko eziphansi.Iphepha elifakwe uthayela lingakhiqizwa libe yikhadibhodi likathayela, bese lenziwa izitayela ezahlukene zamabhokisi ngokuya ngama-oda wamakhasimende:

1. Ikhadibhodi likathayela elinohlangothi olulodwa ngokuvamile lisetshenziswa njengongqimba oluvikela ulwelwesi lokupakishwa kwempahla noma ukwenza amagridi ekhadi elilula namaphedi ukuze kuvikelwe impahla ekudlidlizeni noma ekungqubuzaneni ngesikhathi sokugcinwa nokuhamba;

2. Ikhadibhodi likathayela elinezingqimba ezintathu noma ezinhlanu lisetshenziselwa ukwenza ukupakishwa kwempahla;

3. Ikhadibhodi likathayela elinezingqimba eziyisikhombisa noma izingqimba eziyishumi nanye lisetshenziswa kakhulu ukwenza amabhokisi okupakisha emikhiqizo yemishini nekagesi, ifenisha, izithuthuthu, nezinto ezinkulu zasendlini.

Ikhadibhodi

Iphepha lebhokisi lebhokisi libizwa nangokuthi i-kraft paper.Iphepha lebhokisi lebhokisi lasekhaya lihlukaniswe ngamabanga amathathu: izinga eliphezulu, elokuqala, kanye nemikhiqizo efanelekayo.Ukuthungwa kwephepha kufanele kube nzima, kube nokumelana nokuqhuma okuphezulu, amandla okucindezela indandatho nokuklebhuka, ngaphezu kokuphikiswa kwamanzi okuphezulu.

Inhloso yephepha lekhadibhodi ukubopha umgogodla wephepha likathayela ukwenza ibhokisi likathayela, elisetshenziselwa ukupakisha izinto zikagesi zasendlini, izidingo zansuku zonke nokunye ukupakisha kwangaphandle, futhi lingasetshenziselwa imvilophu, izikhwama zokuthenga, izikhwama zamaphepha, izikhwama zikasimende. , njll.

Iphepha elimhlophe

Kunezinhlobo ezimbili zephepha lebhodi elimhlophe, eyodwa eyokunyathelisa, okusho ukuthi “iphepha lebhodi elimhlophe” ngamafuphi;enye ibhekisela ngokukhethekile ephepheni lokubhala elifanele ibhodi elimhlophe.

Ngenxa yokuthi isakhiwo se-fiber yephepha elimhlophe siyafana, ungqimba olungaphezulu lune-filler kanye nokwakheka kwenjoloba, futhi ingaphezulu limbozwe ngenani elithile lopende, futhi licutshungulwe nge-multi-roll calendering, ukuthungwa kwe-paperboard kuhlangene ngokuqhathaniswa. futhi ukushuba kuyafana.

Umehluko phakathi kwephepha lebhodi elimhlophe nephepha eliboshwe, i-offset paper, nephepha le-letterpress yisisindo sephepha, iphepha elikhudlwana, nemibala ehlukene yangaphambili nangemuva.Ibhodi elimhlophe limpunga ngakolunye uhlangothi futhi limhlophe ngakolunye uhlangothi, elibizwa nangokuthi grey coated white.

Iphepha lebhodi elimhlophe limhlophe futhi libushelelezi, limunca uyinki ofanayo kakhulu, impushana encane kanye ne-lint ngaphezulu, iphepha eliqinile futhi likwazi ukumelana kangcono nokugoqa, kodwa amanzi alo aphakeme kakhulu, futhi asetshenziselwa ikakhulukazi ukuphrinta umbala owodwa Emva kokuphrinta umbala ongaphezulu, wenziwa. emabhokisini okupakishwa, noma asetshenziselwa ukwakheka kanye nemikhiqizo eyenziwe ngezandla.

Ikhadibhodi elimhlophe

Ikhadibhodi elimhlophe liwungqimba olulodwa noma ungqimba oluningi lwephepha elihlanganisiwe elenziwe ngokuphelele nge-bleached chemical pulping kanye nosayizi ogcwele.Ivamise ukuhlukaniswa ngekhadibhodi le-copperplate elihlaza okwesibhakabhaka nelimhlophe elinohlangothi olulodwa, ikhadibhodi le-copperplate elimhlophe-phansi, kanye nekhadibhodi le-copperplate elimpunga-phansi.

Iphepha le-Sika elihlaza okwesibhakabhaka nelimhlophe elinezinhlangothi ezimbili zethusi: Ihlukaniswe ngephepha le-Sika nethusi le-Sika, iphepha le-Sika lisetshenziselwa kakhulu amakhadi ebhizinisi, izimemo zomshado, amakhadi okuposa, njll.;I-Copper Sika isetshenziswa kakhulu kumakhava ezincwadi nawomagazini, amakhadi okuposa, amakhadi, njll. adinga Ikhathoni lokuphrinta elihle.

Ikhadibhodi elinamekwe elinengemuva elimhlophe: Ikakhulukazi isetshenziselwa ukwenza amabhokisi ebanga eliphezulu kanye nokupakishwa kwamabhamuza e-vacuum.Ngakho-ke, iphepha kufanele libe nezici zokuba mhlophe okuphezulu, ingaphezulu lephepha elibushelelezi, ukwamukeleka kahle kweyinki, kanye nesicwebezelisi esihle.

Ikhadibhodi le-copperplate elimpunga eliphansi: ungqimba olungaphezulu lisebenzisa i-pulp yamakhemikhali amhlophe, izingqimba eziwumgogodla nezingezansi ziyi-kraft pulp engaxutshiwe, i-pulp yokhuni lomhlabathi noma iphepha elihlanzekile lemfucuza, elifanele ukuphrinta umbala wamabhokisi amabhokisi aphezulu, ikakhulukazi asetshenziselwa ukwenza amabhokisi amabhokisi ahlukahlukene. namakhava ezincwadi ezinoqwembe oluqinile .

Iphepha lokukopisha liwuhlobo lwephepha elithuthukisiwe lamasiko nezimboni okunzima ukulikhiqiza.Izici eziyinhloko zobuchwepheshe yilezi: amandla aphezulu omzimba, ukufana okuhle kakhulu nokungafihli lutho, kanye nezakhiwo ezinhle zangaphezulu, ezicolekileyo, eziyisicaba, ezibushelelezi, nesihlabathi esingenagwebu, ukuphrinta okuhle.

Iphepha lokukopisha liwuhlobo lwephepha elithuthukisiwe lamasiko nezimboni okunzima kakhulu ukulikhiqiza.Izici eziyinhloko zobuchwepheshe zalo mkhiqizo zimi kanje: amandla aphezulu ngokomzimba, ukufana okuhle kakhulu nokungafihli, kanye nezakhiwo ezinhle zokubukeka, ezinhle, ezibushelelezi futhi ezibushelelezi , Asikho isihlabathi se-bubble, ukuphrinta okuhle.Ngokuvamile, ukukhiqizwa kwephepha lokunyathelisa kuhlukaniswe izinqubo ezimbili eziyisisekelo: i-pulp kanye ne-papermaking.I-Pulp ukusetshenziswa kwezindlela zemishini, izindlela zamakhemikhali noma inhlanganisela yezindlela ezimbili zokuhlukanisa imicu yezitshalo eluhlaza ibe yi-pulp yemvelo noma i-bleached pulp.Ekwenziweni kwamaphepha, imicu ye-pulp elenga emanzini ihlanganiswa ngezinqubo ezihlukahlukene zibe amaphepha amaphepha ahlangabezana nezidingo ezihlukahlukene.
