Kusukela ekuguqulweni kwemilingo ukusuka esihlahleni kuya ephepheni, iyiphi inqubo eyadlula kuyo futhi yayinaluphi uhlobo lwendaba? Lokhu akuwona umsebenzi olula. Azikho izendlalelo zezinqubo kuphela, kodwa futhi nezindinganiso eziphakeme kanye nezidingo eziqinile. Kulokhu, ake singeneUmshini wokugaya we-APPukuhlola iphepha kusuka ku-0 kuye ku-1.
Angene efemini
Ngemva kokungena embonini, izinto zokusetshenziswa zokhuni zisikwa zibe ubude obuhlangabezana nezidingo zemishini, bese kuba ijazi (amagxolo) elingahambisani nekhwalithi ye-pulp liyaxetshulwa. Iyunifomu kanye nezicucu zokhuni ezisezingeni eliphezulu zithunyelwa esigabeni sokupheka amapulangwe ngohlelo lokudlulisa oluvaliwe. Izingcezu zokhuni ezisele ziyachotshozwa bese zishiswa kubhayela ukuze kukhiqizwe ugesi. Amanzi noma ezinye izinto ezikhiqizwa ngesikhathi sokucubungula zizogaywa kabusha zibe ugesi noma isitimu.
I-pulping ezenzakalelayo
Inqubo ye-pulping ihlanganisa ukupheka, ukususwa kokungcola, ukukhishwa kwe-lignin, ukucwecwa, ukuhlungwa kwamanzi, nokwakheka, njll. Ukuhlolwa kobuchwepheshe kuphezulu kakhulu, futhi yonke imininingwane izothinta ikhwalithi yephepha.
I-pulp yokhuni ephekiwe ithunyelwa esigabeni se-oxygen delignification ngemva kokuba ukungcola kususwe esigabeni sokuhlola, lapho i-lignin e-pulp yokhuni isuswa futhi ukuze i-pulp ibe nekhono elingcono le-bleach. Bese ufaka isigaba esithuthukisiwe sokuhlanza i-chlorine esinezigaba ezine se-elementi engenasici, bese uhlanganisa nemishini yokugeza i-pulp esebenza kahle kakhulu ukuze uqiniseke ukuthi i-pulp ephumayo inezici zekhwalithi ezinzile, ubumhlophe obuphezulu, ukuhlanzeka okuphezulu, kanye nezakhiwo zomzimba eziphakeme.
Ukukhiqiza okuhlanzekile
Ngesikhathi sokupheka kwe-wood chip, kukhiqizwa inani elikhulu loketshezi olunsundu (olwaziwa ngokuthi "utshwala olumnyama") oluqukethe i-alkaline lignin. Ubunzima bokwelapha uphuzo oludakayo sebuphenduke umsuka omkhulu wokungcola ezinkampanini ze-pulp nephepha.
Uhlelo oluthuthukisiwe lokubuyisela i-alkali lube selusetshenziswa ukugxilisa izinto eziwugqinsi ngokuhwamuka bese kushisa kubhayela. Isitimu esinomfutho ophezulu okhiqizwayo sisetshenziselwa ukukhiqiza ugesi, ongahlangabezana nezidingo zamandla ezingaba ngu-90% zolayini wokukhiqiza u-pulp, futhi isitimu esinengcindezi ephakathi nendawo nesiphansi singasetshenziswa kabusha ekukhiqizeni.
Ngesikhathi esifanayo, i-alkali edingekayo enqubweni ye-pulping ingaphinda isetshenziswe ohlelweni lokubuyisela i-alkali. Lokhu akunciphisi kuphela izindleko zokukhiqiza kodwa futhi kufeza ukuvikelwa kwemvelo, ukongiwa kwamandla, nokunciphisa ukungcola.
Iphepha eliphelile
I-pulpboard eyenziwe yasikwa ngomsiki wephepha ibe imininingwane yesisindo nosayizi othile bese ithuthelwa kulayini wokupakisha ngamunye.
Ukuze kube lula ukuhamba, kunamapulangwe aqediwe ebhandeni lokuthutha, futhi wonke ahlungwa ngemva kobumhlophe kanye nesilinganiso sokungcola.
Izinto zokusebenza zisebenza ngokuzenzakalelayo ngokugcwele, zikhipha amathani angu-3,000 nsuku zonke. Ngaphandle ngesikhathi sokulungiswa komshini, ezinye izikhathi zisebenza ngokungaphazamiseki.
Ezokuthutha
Ngemuva kokuthi i-roll packer elandelayo ihlanganise i-pulpboard, izosongwa ngongqimba lwephepha ukuze kube lula ukupakisha nokuthuthwa okulandelayo, futhi nokugwema ukungcoliswa kwe-pulpboard ngesikhathi sokuthutha.
Kusukela lapho, umshini we-inkjet ufafaza inombolo ye-serial, usuku lokukhiqiza, kanye nekhodi ye-QR yeibhodi le-pulp . Ungakwazi ukulandelela umsuka we-pulp ngokusekelwe olwazini lwesifutho sekhodi ukuze uqinisekise ukuthi "iketango" aliphukile.
Bese isitaki sinqwabelanisa izikhwama ezincane eziyisishiyagalombili esikhwameni esisodwa esikhulu futhi ekugcineni silungise ngomshini wokubopha, olungele ukusebenza kwe-forklift kanye nemisebenzi yokuphakamisa idokhu ngemva kokungaxhunyiwe ku-inthanethi nokugcinwa kwempahla.
Lesi isiphetho sesixhumanisi "se-pulp". Ngemva kokutshala ihlathi nokwenza i-pulp, iphepha lizokwenziwa kanjani ngokulandelayo? Sicela ulinde imibiko yokulandelela.
