Kunezinhlobo eziningi zezinto zokupakisha, akukho okungcono kakhulu, kuphela ezifanele kakhulu.Phakathi kwazo, ibhokisi lokupakisha likathayela lingenye yezinto ezikhethiwe kakhulu.Ngenxa yesakhiwo esikhethekile sephepha likathayela, uhlelo lokupakisha olukhanyayo noluqinile lungakhiwa.
Iyini impahla kathayela?
Ibhodi likathayela, elaziwa nangokuthi ibhodi likathayela, lenziwe ngemicu engasindi enwetshiwe, engatholwa emiculweni eluhlaza noma ebhodini likathayela elisetshenzisiwe nezinye izinto.
Ikhadibhodi likathayela isakhiwo esakhiwe kusuka kuthayela owodwa noma ngaphezulu (okuthiwa "iphepha lesisekelo" noma "ama-corrugates") anamathiselwe ishidi elilodwa noma ngaphezulu "lamakhadibhodi" nge-adhesive efakwe phezulu kwama-corrugtes.
Inombolo yephepha lobuso nephepha eliwumgogodla lebhodi likathayela linquma isigaba: uhlangothi olulodwa lukathayela, ungqimba olulodwa lukathayela, ungqimba oluphindwe kabili lukathayela, ungqimba oluthathu lukathayela nokunye.Ngokusho kwe-ripple ihlukaniswe: A,B,C,E,F kathayela.Lawa ma-corrugations aqanjwa ngokuhambisana nobukhulu, ubude kanye nenani lama-ripples.
Isendlalelo esisodwa sikathayela ngokuvamile sisetshenziswa ku-A, B, C kukathayela, i-BC eboshiwe ingenye yebhodi likathayela eliphindwe kabili elivame kakhulu.Izendlalelo ezintathu zama-corrugations, ezinama-ACC corrugations, ABA corrugations nezinye izigaba, zivame ukusetshenziselwa ukupakishwa kwemikhiqizo esindayo, kuye ngomkhiqizi nendawo.
Ukupakishwa okufakwe uthayela kungafika ngezitayela ezahlukene, ukwakheka nosayizi kuye ngohlelo lokusebenza.Izinhlangano zamazwe ngamazwe, ezifana ne-FEFCO e-Europe, zinezakhiwo zamaphepha zikathayela.
Izinhlobo ezahlukene zamakhadibhodi
Nakuba amabhokisi kathayela amaningi abukeka afana, enziwe ngezinhlobo ezahlukene zezinto, ezingaba nomthelela omkhulu ezicini zawo nasekusebenzeni kokupakisha.Izinhlobo eziningana zekhadibhodi zimi kanje:
Ibhodi lephepha le-Kraft
Amabhodi ephepha e-Kraft aqukethe okungenani ama-70-80% emicu yasekuqaleni yamakhemikhali.Zibhekwa njengezinto eziphakeme kakhulu zebanga, ziqinile kakhulu futhi ziqinile, ezinobuso obushelelezi.Amabhodi wephepha amaningi e-kraft enziwe nge-softwood pulp, kanti amanye enziwe nge-birch kanye namanye amapulangwe okhuni aqinile.Amabhodi wephepha e-Kraft angahlukaniswa ngezigaba eziningana ngokuya ngombala wawo:
Umbala onsundu wemvelo wamapuleti ephepha e-brown kraft uzohluka, kuye nge-fiber, inqubo yokudonsa, kanye nendawo yesitshalo.
Iphepha elimhlophe le-kraft linamandla kakhulu futhi linenani elifanele.
Ibhodi lephepha le-kraft elimpunga, elaziwa nangokuthi ibhodi lephepha le-oyster, lifana nebhodi lephepha le-kraft elimhlophe, kodwa linokubukeka okuhlukahlukene.
Amabhodi ephepha e-kraft ane-bleached abukeka engokwemvelo, kodwa adlula esigabeni esengeziwe sokuhlanza.Abanamandla njengephepha lezandla elingaxutshiwe.
Iphepha le-birch veneer kraft lenziwe ngezinto ezifana nephepha elimhlophe le-veneer kraft, kodwa elinobuso obumhlophe.Lokhu kunciphisa umthelela wemvelo wekhadibhodi.
Ibhodi lekhadi lenkomo lokulingisa
Amandla ebhodi lekhadi le-bovine lokulingisa awekho phezulu njengalawo ebhodi lephepha le-kraft, ngoba elokuqala linokuqukethwe okuphezulu kwe-fiber egaywe kabusha.Kubalulekile ukuqaphela ukuthi amakhadibhodi okulingisa ama-brown bovine angahlukaniswa ngezigaba ezahlukene, nakuba lezi zizohluka ngezwe nesifunda.
Ikhadibhodi evamile
Ikhadibhodi elivamile alivamile njengephepha le-kraft noma ikhadi le-bovine lokulingisa elinsundu.Ikakhulukazi zenziwe ngezinto ezingalawulwa ezigaywe kabusha, okusho ukuthi azizona ezekhwalithi ephezulu futhi azihlinzeki ngokusebenza okufanayo nezinye izinhlobo zamakhadibhodi.Kunezinhlobo ezintathu zamakhadibhodi ajwayelekile:
Ikhadibhodi elimhlophe,ngokuvamile mhlophe.
Ikhadibhodi elimhlophe,usebenzisa ikhadibhodi elakhiwe nge-laminated, libukeka lifana nekhadibhodi elifakwe i-bleached, nakuba lishibhile.
Ikhadibhodi empunga,ngokuvamile isetshenziswa kuphela njengephepha core.
Kunezinye izici okufanele zicatshangelwe.Isibonelo, ukupakishwa kukathayela kungaqukatha izingqimba ezilodwa, ezikabili noma ezintathu.Izendlalelo eziningi, iphakheji lizoba namandla futhi lihlala isikhathi eside, kodwa ngokuvamile libiza kakhulu.
Yini okufanele siyicabangele lapho sikhetha amaphakheji kathayela?
Ezimweni eziningi, ukupakishwa kukathayela kuyiphakheji efanelekile.Okokuqala, ngenxa yokuthi iyakwazi ukugaywa kabusha ngo-100%, iyisinqumo esihle ezinkampanini eziqaphela imvelo, ikakhulukazi njengoba ukusimama kuya ngokuya kuba semqoka emabhizinisini amaningi.
Ukupakishwa kukathayela nakho kunezici zokwenza ngokwezifiso.Ungashintsha uhlobo lwekhadibhodi, ingcina esetshenzisiwe kanye nosayizi we-corrugator.Isibonelo, amaphakheji kathayela angase abe nesendlalelo se-retardant engezwe kukho ukuze sisetshenziswe lapho kuthuthwa izinto ezivuthayo noma ezimelana nomswakama ezichayeke kumswakama ophezulu noma ukuhluka okubanzi kwezinga lokushisa.
Lolu hlobo lokupakisha lunamandla kakhulu ngesisindo salo futhi lungavikela izinto ezibuthakathaka ngesikhathi sokuthutha.Imikhiqizo ipakishwa phakathi kwezingqimba zephepha likathayela eliqine ngokwanele ukumelana nokucindezela okukhulu noma ukudlidliza.Lezi zikesi zokupakisha zingavimbela imikhiqizo ukuthi ingasheleli futhi ingamelana nokudlidliza okuphezulu.
Ekugcineni, impahla ibiza kakhulu.Ingenye yezinketho ezishibhe kakhulu ezitholakalayo, futhi, ngenxa yalokho, iyisinqumo esihle kulabo abafuna ukunciphisa izindleko zokupakisha ngaphandle kokubeka engcupheni ukuvikelwa komkhiqizo.
