Ekugelezeni kokucubungula amaphepha amdaka embonini yokwenza amaphepha, isihlukanisi sefayibha siwumshini obalulekile wokwenza i-defibre yephepha elimdaka isebenze kahle futhi iqinisekise ikhwalithi ye-pulp. I-pulp ephathwa yi-hydraulic pulper isenamaphepha amancane angahlakazekile. Uma imishini yokushaya evamile isetshenziselwa ukususa i-fiber yephepha elimdaka, akukhona nje kuphela ukuthi ukusetshenziswa kwamandla kuphezulu futhi izinga lokusetshenziswa kwemishini liphansi, kodwa futhi namandla e-pulp azokwehla ngenxa yokusikwa kabusha kwefayibha. Isihlukanisi sefayibha singasabalalisa imicu ngokuphelele ngaphandle kokuyisika, futhi sesibe umshini wokususa ifayibha wephepha elimdaka osetshenziswa kabanzi njengamanje.

Ukuhlukaniswa Kwabahlukanisi Befayibha

Ngokuya ngomehluko wesakhiwo nomsebenzi, abahlukanisi befayibha bahlukaniswe kakhulu ngezinhlobo ezimbili:abahlukanisi befayibha abanomphumela owodwafuthiabahlukanisi befayibha ehlanganisiwe.

Isihlukanisi Sefayibha Esinomphumela Owodwa: Isakhiwo Esihlakaniphile, Umsebenzi Ocacile

Isihlukanisi sefayibha esinomphumela owodwa sinomklamo wokwakheka ohlakaniphile (njengoba kuboniswe kumdwebo wokusebenza weSithombe 5-17). Umgomo waso wokusebenza umi kanje: i-pulp iphonswa ekugcineni okunobubanzi obuncane begobolondo eliyindilinga kusuka phezulu ngendlela eqondile. Lapho i-impeller ijikeleza, ama-blade nawo anomsebenzi wokupompa, okwenza i-pulp ikhiqize ukujikeleza kwe-axial kanye nokujikeleza okunamandla okuguquguqukayo. Esikhaleni esiphakathi komphetho we-impeller nommese ongezansi, naphakathi kwe-impeller ne-screen plate, i-pulp iyasuswa i-fiber bese ihlukaniswa ibe imicu.

• Ukuhlukaniswa Okuhle Kwe-Pulp: Ummese ongaphansi wokuhlukanisa oqinile osemaphethelweni e-impeller awukhuthazi nje kuphela ukuhlukaniswa kwefayibha, kodwa futhi udala ukuxokozela kokusesha imigodi yesikrini, bese kuthi i-pulp enhle ekugcineni ithunyelwe isuka emigodini yesikrini ngemuva kwe-impeller.
• Ukususwa Kokungcola: Ukungcola okulula okufana namafilimu epulasitiki kugxile ku-axis ngenxa yomphumela wamanje we-eddy, futhi kukhishwa njalo kusuka endaweni ephakathi yesembozo sangaphambili kanye nengxenye encane ye-pulp exubile; ukungcola okunzima kufakwa ngaphansi kwamandla e-centrifugal bese kungena echwebeni lokukhipha i-slag ngaphansi kokuphela kobubanzi obukhulu eceleni komugqa ongaphakathi wodonga ukuze kukhishwe.

Ngokuphathelene nokulawula ukusebenza, isikhathi sokuvula kwevalvu yokukhipha ukungcola kokukhanya sidinga ukulungiswa ngokuya ngokuqukethwe kokungcola kokukhanya ezintweni zokusetshenziswa zefayibha yephepha elingcolile. Ngokuvamile, ukulawula okuzenzakalelayo kukhipha kanye njalo ngemva kwamasekhondi ayi-10-40, isikhathi ngasinye amasekhondi angu-2-5; ukungcola okunzima kukhishwa kanye njalo ngemva kwamahora ama-2. Ngokulawula ukukhishwa okunembile, kungahlukanisa ngokuphelele imicu ngenkathi kugwema ukuphula ukungcola kokukhanya njengepulasitiki, futhi kubuyisele ngokushesha ibhalansi yokuhlukanisa, ekugcineni kuqaphele ukuhlukaniswa nokuhlanzwa kwemicu.

Ngomklamo wayo oyingqayizivele wesakhiwo kanye nendlela yokusebenza, isihlukanisi sefayibha sibonisa izinzuzo ezibalulekile enqubweni yokususa i-waste paper defiber. Ayixazululi nje kuphela izinkinga zemishini yokushaya evamile, kodwa futhi iqeda ngempumelelo imisebenzi yokuhlakazwa kwefayibha kanye nokuhlukanisa ukungcola, ibeka isisekelo esiqinile sokuthuthukisa ikhwalithi ye-waste paper pulp kanye nokuqinisekisa ukusebenza kahle kokukhiqizwa kwephepha. Ingenye yemishini ebalulekile ebalulekile ekucutshungulweni kwephepha lemfucuza embonini yanamuhla yokwenza iphepha.
