Ngokuqhelekileyo, izinto zokupakisha zephepha eziqhelekileyo ziquka iphepha elimdaka, iphepha lekhadibhodi, iphepha lebhodi elimhlophe, ikhadibhodi emhlophe, igolide kunye nekhadibhodi yesilivere, njl. Iziphumo ezikhuselayo.
iphepha elimdaka
Ngokohlobo lwefleyiti, iphepha elimdaka linokwahlulwa libe ziindidi ezisixhenxe: Umngxuma, B, C, D, E, F, kunye noG. Phakathi kwazo, imingxuma A, B, kunye no-C isetyenziswa ngokubanzi ukupakishwa kwangaphandle, kunye ne-D, i-E imigodi Ngokuqhelekileyo isetyenziselwa ukupakisha okuncinci naphakathi.
Iphepha eligutyungelweyo lineenzuzo zokukhanya kunye nokuqina, umthwalo onamandla kunye nokumelana noxinzelelo, ukuxhathisa ukothuka, ukuxhathisa ukufuma, kunye neendleko eziphantsi. Iphepha elonakeleyo linokuveliswa libe yikhadibhodi, kwaye emva koko lenziwe kwiindlela ezahlukeneyo zeebhokisi ngokwemiyalelo yabathengi:
1. Ikhadibhodi yethanki enecala elinye isetyenziswa ngokubanzi njengomaleko okhuselayo wokupakishwa kwempahla okanye ukwenza iigridi zekhadi elikhanyayo kunye neepads ukukhusela impahla ekungcangcazeleni okanye ukungqubana ngexesha lokugcinwa nokuthutha;
2. Ikhadibhodi enezintlu ezintathu okanye emihlanu isetyenziselwa ukwenza ukuthengiswa kwempahla;
3. Ikhadibhodi enamaleko asixhenxe okanye eleshumi elinanye isetyenziselwa ukwenza iibhokisi zokupakisha zemveliso yomatshini kunye nombane, ifenitshala, izithuthuthu, kunye nezixhobo ezinkulu zendlu.
Ikhadibhodi
Iphepha lebhokisi lebhokisi likwabizwa ngokuba yi-kraft paper. Iphepha lebhokisi yebhokisi yasekhaya yahlulwe yangamanqanaba amathathu: umgangatho ophezulu, udidi lokuqala, kunye neemveliso ezifanelekileyo. Ubume bephepha kufuneka bube bunzima, bube nokumelana nokugqabhuka okuphezulu, ukunyanzeliswa kwe-ring kunye nokukrazula, ngaphezu kokuchasana kwamanzi.
Injongo yephepha lekhadibhodi kukudibanisa nombindi wephepha le-corrugated core ukwenza ibhokisi ye-corrugated, esetyenziselwa ukupakisha izixhobo zasekhaya, iimfuno zemihla ngemihla kunye nezinye iipakethe zangaphandle, kwaye ingasetyenziselwa iimvulophu, izikhwama zokuthenga, izikhwama zephepha, iingxowa zesamente. , njl.
Iphepha elimhlophe
Zimbini iindidi zephepha lebhodi emhlophe, enye yeyokushicilela, okuthetha “iphepha lebhodi emhlophe” ngokufutshane; enye ibhekisa ngokukodwa kwiphepha lokubhala elilungele ibhodi emhlophe.
Ngenxa yokuba ulwakhiwo lwefiber yephepha elimhlophe lufana ngokufanayo, umaleko womphezulu une-fiber kunye nokwakheka kwerabha, kwaye umphezulu ugqunywe ngomlinganiselo othile wepeyinti, kwaye ucutshungulwe yi-multi-roll calendering, ukuthungwa kwe-paperboard kuhambelana noko. kwaye ubukhulu bufana.
Umahluko phakathi kwephepha lebhodi elimhlophe kunye nephepha eligqunyiweyo, i-offset paper, kunye nephepha le-letterpress bubunzima bephepha, iphepha elinzima, kunye nemibala eyahlukeneyo yangaphambili nangemuva. Ibhodi emhlophe ingwevu kwelinye icala kwaye imhlophe kwelinye icala, ekwabizwa ngokuba grey coated white.
Iphepha lebhodi emhlophe limhlophe kwaye ligudileyo, linokufakwa kwe-inki efanayo ngakumbi, umgubo omncinci kunye nentambo phezu komhlaba, iphepha elinamandla kunye nokumelana nokugoqa okungcono, kodwa umxholo walo wamanzi uphezulu, kwaye usetyenziselwa i-single emva kokushicilelwa kombala womphezulu, uyenziwa. kwiibhokisi zokupakisha, okanye ezisetyenziselwa ukuyila kunye neemveliso ezenziwe ngezandla.
Ikhadibhodi emhlophe
Ikhadibhodi emhlophe yi-single-layer okanye i-multi-layer edityanisiweyo yephepha elenziwe ngokupheleleyo nge-bleached chemical pulping kunye nobukhulu obupheleleyo. Ngokuqhelekileyo yahlulahlulwe ibe yikhadibhodi yobhedu eblue namhlophe enecala elinye, icopperplate emhlophe-ezantsi emhlophe, kunye ne-grey-bottomed copperplate cardboard.
Iphepha le-Sika elihlaza okwesibhakabhaka kunye elimhlophe elinamacala amabini obhedu: Ukwahlulwe kwiphepha leSika kunye nobhedu lweSika, iphepha leSika lisetyenziswa kakhulu kumakhadi oshishino, izimemo zomtshato, iiposikhadi, njl.; ICopper Sika isetyenziswa ikakhulu kuqweqwe lwencwadi kunye neemagazini, iiposikhadi, amakhadi, njl.njl. ezifuna iKhathoni yokushicilela kakuhle.
Ikhadibhodi egqunywe ngasemva emhlophe: Isetyenziswa ikakhulu ukwenza iikhathoni zodidi oluphezulu kunye nokupakishwa kwe-vacuum blister. Ke ngoko, iphepha kufuneka libe neempawu zobumhlophe obuphezulu, umphezulu wephepha ogudileyo, ukwamkeleka kakuhle kwe-inki, kunye neglosi elungileyo.
Ikhadibhodi yobhedu enegrey-esezantsi: umaleko womphezulu usebenzisa ipulp yekhemikhali exutyiweyo, undoqo kunye nomgangatho osezantsi yintlama yekraft engaxutywanga, intlama yeplanga yomhlaba okanye inkunkuma ecocekileyo yephepha, ilungele ukuprintwa kombala weebhokisi zeekhathoni eziphezulu, ezisetyenziselwa ukwenza iibhokisi zeebhokisi ezahlukeneyo. namaqweqwe eencwadi ezinoqweqwe olulukhuni .
Iphepha lokukopa luhlobo lwephepha eliphambili lenkcubeko kunye neshishini ekunzima ukulivelisa. Iimpawu eziphambili zobuchwephesha zezi: amandla aphezulu omzimba, ukufana okugqwesileyo kunye nokungafihli, kunye neempawu ezintle zomphezulu, ezicolekileyo, ezisicaba, ezigudileyo, kunye neSanti engenagwebu, ukuprinta kakuhle.
Iphepha lokukopa luhlobo lwephepha eliphambili lenkcubeko kunye neshishini ekunzima kakhulu ukulivelisa. Iimpawu eziphambili zezobugcisa zale mveliso zimi ngolu hlobo lulandelayo: amandla aphezulu omzimba, ukufana okugqwesileyo kunye nokungafihli, kunye neempawu ezintle zokubonakala, ezintle, ezigudileyo kwaye ezigudileyo , Akukho sihlabathi se-bubble, ukuprintwa kakuhle. Ngokuqhelekileyo, ukuveliswa kwephepha lokushicilela kwahlulwe kwiinkqubo ezimbini ezisisiseko: i-pulp kunye ne-papermaking. Intlama kukusetyenziswa kweendlela zoomatshini, iindlela zekhemikhali okanye indibaniselwano yeendlela ezimbini zokwahlula imathiriyeli ekrwada yefayibha yezityalo ibe yintlaka yendalo okanye intlama eblitshi. Ekwenziweni kwephepha, imicu yepulp emiswe emanzini idityaniswe ngeenkqubo ezahlukeneyo zibe ngamaphepha ahlangabezana neemfuno ezahlukeneyo.
