Indlela yokulungelelanisa inkqubo ye-inki ye-flexo yokushicilela ngephepha lebhokisi lebhokisi
Iindidi eziqhelekileyo zesiseko sephepha elisetyenziswa kwibhokisi yebhokisi ye-corrugated surface paper ziquka: iphepha lebhodi yesikhongozeli, i-liner paper, i-kraft cardboard, iphepha lebhodi yeti, iphepha lebhodi elimhlophe kunye necala elinye elicatshulwe ngebhodi emhlophe. Ngenxa yokungafani kwezinto zokwenziwa kwephepha kunye neenkqubo zokwenza iphepha lohlobo ngalunye lwesiseko sephepha, izibonakaliso ezibonakalayo kunye neekhemikhali, izakhiwo ezingaphezulu kunye nokuprintwa kwamaphepha esiseko akhankanywe ngasentla ahluke kakhulu. Oku kulandelayo kuya kuxoxa ngeengxaki ezibangelwa zezi mveliso zephepha ezikhankanywe ngasentla kwikhadibhodi ye-inki ye-inki yokushicilela ukuqalisa inkqubo.
1. Iingxaki ezibangelwa yi-low-gram base paper ibhokisi yetshokolethi
Xa i-low-gram base paper isetyenziswe njengephepha elingaphezulu lekhadibhodi ye-corrugated, amanqaku angamalahle aya kubonakala kumphezulu wekhadibhodi edibeneyo. Kulula ukwenza ifluthi kwaye umxholo wegraphic ofunekayo awunakuprintwa kwindawo ephantsi ye-concave yefleyiti. Ngokujonga umphezulu ongalinganiyo wekhadibhodi ekhuniweyo ebangelwa yifluti, ipleyiti ye-resin eguquguqukayo enokuqina okungcono kufuneka isetyenziswe njengepleyiti yokushicilela ukoyisa izitenxo zokushicilela. Iziphene ezicacileyo nezibhencekileyo. Ngokukodwa kwi-A-type corrugated cardboard eveliswa kwiphepha le-low-grammage, i-flat compressive force of cardboard corrugated cardboard iya konakala kakhulu emva kokushicilelwa ngumatshini wokushicilela. Kukho umonakalo omkhulu.ubucwebeibhokisi
Ukuba ubuso obuphezulu bekhadibhodi ebotyiweyo buhluke kakhulu, kulula ukubangela ukuba i-warping yekhadibhodi edibeneyo eveliswe ngumgca wekhadibhodi. Ikhadibhodi ephothiweyo iya kubangela ukuprintwa okungachanekanga kunye neendawo zokuprinta ngaphandle kwe-gauge yokuprinta, ngoko ke ikhadibhodi ephothiweyo kufuneka ibe mcaba phambi kokushicilela. Ukuba ikhadibhodi engalinganiyo ishicilelwe ngenkani, kulula ukubangela izitenxo. Kwakhona kuya kubangela ukuba ubukhulu bekhadibhodi eboshiweyo buyancipha.
2. Iingxaki ezibangelwa buburhabaxa obuhlukeneyo bomphezulu bephepha lesiseko iphepha-isipho-ukupakishwa
Xa uprinta kwiphepha elisisiseko elinomgangatho orhabaxa kunye nolwakhiwo oluxengaxengayo, i-inki inokungena okuphezulu kwaye i-inki yokuprinta yoma ngokukhawuleza, ngelixa uprinta kwiphepha elinobushelelezi obuphezulu, ifayibha eshinyeneyo kunye nokuqina, isantya sokumisa i-inki siyacotha. Ngoko ke, kwiphepha eligqithisiweyo, inani le-inki yesicelo kufuneka linyuswe, kwaye kwiphepha eligudileyo, inani le-inki yesicelo kufuneka lincitshiswe. I-inki eprintiweyo kwiphepha elingalinganiyo yoma ngokukhawuleza, ngelixa i-inki eprintiweyo kwiphepha elilinganisiweyo yoma kancinane, kodwa ukuveliswa kwakhona kwepateni eprintiweyo kulungile. Umzekelo, ukufunxwa kwe-inki yephepha lebhodi emhlophe egqunyiweyo kungaphantsi kwephepha lebhokisi kunye nephepha le-teaboard, kwaye i-inki yoma kancinane, kwaye ukuguda kwayo kuphezulu kunoko kwe-boxboard paper, i-liner paper kunye ne-teaboard paper. Ngoko ke, isisombululo samachaphaza amahle ashicilelwe kuyo Ireyithi nayo iphezulu, kwaye ukuphindaphinda kwepateni yayo kungcono kunephepha le-liner, iphepha lekhadibhodi, kunye nephepha lebhodi yeti.
3. Iingxaki ezibangelwa yiyantlukwano kwisiseko sephepha lokufunxa ibhokisi yomhla
Ngenxa yomahluko wokwenza amaphepha ezinto ezikrwada kunye nobungakanani bephepha elisisiseko, ikhalenda, kunye nomahluko wokugquma, amandla okufunxa ahlukile. Umzekelo, xa uprinta ngokugqithisileyo kwiphepha lebhodi emhlophe enecala elinye kunye namakhadi e-kraft, isantya sokumisa i-inki siyacotha ngenxa yokusebenza okuphantsi kokufunxa. Kancinci, ngoko ukugxininiswa kwe-inki yangaphambili kufuneka kuncitshiswe, kwaye i-viscosity ye-inki yokuprinta elandelayo kufuneka inyuswe. Shicilela imigca, iimpawu, kunye neepatheni ezincinci kumbala wokuqala, kwaye uprinte ipleyiti epheleleyo kumbala wokugqibela, onokuphucula umphumo wokugqithisa. Ukongeza, printa umbala omnyama ngaphambili kunye nombala okhanyayo ngasemva. Iyakwazi ukugubungela impazamo yokuprintwa kwe-overprint, kuba umbala omnyama unokhuselo oluqinileyo, ohambelana nomgangatho ogqithisiweyo, ngelixa umbala okhanyayo unokhuselo olubuthathaka, kwaye akulula ukuwujonga nokuba kukho into ebalekile ekushicileleni. ibhokisi yomhla
Iimeko ezahlukeneyo zokulinganisa kumgangatho wephepha wesiseko nazo ziyakuchaphazela ukufunxwa kwe-inki. Iphepha elinexabiso elincinci lokulinganisa lifunxa i-inki eninzi, kwaye iphepha elinesixa esikhulu sokulinganisa lifunxa i-inki encinci. Ngoko ke, umsantsa phakathi kwee-inki rollers kufuneka ulungelelaniswe ngokwesimo sokulinganisa iphepha, oko kukuthi, umsantsa phakathi kwee-inki rollers kufuneka uncitshiswe ukulawula ipleyiti yokushicilela. ye-inki. Inokubonwa ukuba xa iphepha lesiseko lingena kumzi-mveliso, ukusebenza kokufunxa kwephepha lesiseko kufuneka kuvavanywe, kwaye iparameter yokufunxwa kwephepha lesiseko kufuneka inikwe umatshini wokushicilela kunye ne-inki dispenser, ukuze banokukhupha i-inki kunye nokulungelelanisa izixhobo. Kwaye ngokwemeko yokufunxa yamaphepha asisiseko ahlukeneyo, lungisa i-viscosity kunye nexabiso le-PH ye-inki.
