Ukuphayipha kubalulekile ngaphambi kokwenza iphepha, okushiya imiphumela emihle ekusebenzeni okuvamile komshini wephepha kanye nekhwalithi yephepha. Izici ezibalulekile ekushayweni ukugcwala kwe-pulp, izinga lokushaya, kanye nesilinganiso se-pulp.
Ukulinganisa Ukugxila Kwe-Pulp
Ukuhlushwa kwe-pulp okungazinzile kungaholela ekhwalithini yephepha engaguquki, futhi kungabangela ukuphuka kwephepha futhi kuphazamise ukwenziwa kwephepha okuvamile okubi nakakhulu. Izici zokungazinzi kokuhlushwa kwe-pulp okungaguquki zincike ekushintsheni kokuhlushwa kwe-pulp eluhlaza kanye nezinto ezilahliwe, ukulungiswa kokuhlushwa ngesandla ekushayweni, ekugxiliseni nasekuxubeni, kanye nohlelo lwamanzi amhlophe olungalingani.
Izinguquko Ekugxilweni Kwe-Raw Pulp
I-pulp ekhishwa endaweni yokusebenzela yokudonsa iyahlukahluka ngokuhlushwa. Ukuhlushwa kokugcina kwe-pulp kuzothinteka uma kungenziwanga ukulungiswa okudingekayo ekuhlushweni.
Ukulungiswa Kokugxila Ekushayweni
Ngesikhathi sokushaya, i-pulp idlula ezinqubweni ezifana nokugxila, ukushaya, nokuxuba, okudinga ukulungiswa kokugxilisa ingqondo. Ezinye izinhlelo zisebenzisapulp di-ensitymi-eter, kodwa ukulungiswa ngesandla kuvame kakhulu. Izinguquko zokugxilisa ingqondo zingase zenzeke ngenxa yokungabi nolwazi komqhubi, ukuntuleka kokukhuthala, noma ukungasebenzi kahle kwemishini.
Izinguquko kuWai-ste StuffUkugxila
Iphepha eliphukile eliphinde lasetshenziswa liyanqunywa ku-hydropulper bese ligxiliswa ezingeni elizinzile ngaphambi kokuncibilikiswa ku-concentration edingekayo. Uma ubuningi bezinto ezilahliwe buhluka kakhulu ngesikhathi sokuphelelwa amanzi emzimbeni kanye nokuncipha, kungaphazamisa uhlelo lwe-pulp iyonke.
Ukungazinzi Ezinhlelweni Zamanzi Amhlophe
Amanzi amhlophe asetshenziswa kabusha ekuxubeni i-pulp ukunciphisa ukusetshenziswa kwamanzi kanye nokulahlekelwa yi-fiber. Uma uhlelo lwamanzi amhlophe lungalingani noma ingcindezi kanye nokugeleza kwawo kungazinzile, kuzothinta ukuxubeka kwe-pulp kanye nokuhlushwa kwayo.
Idigri Yokunqoba
Izinto eziningana zithonya ukushaywa kwe-pulp, njengokucindezela, ukugxilisa ingqondo, izinga lokugeleza, isikhathi, izinga lokushisa, isimo se-blade, kanye nekhono lomsebenzisi. Uma noma yisiphi isinyathelo singaphathwanga kahle, ikhwalithi yokushaywa kwe-pulp izothinteka. Ukuzinzisa ukushaywa kuyinselele ngaphandle kokuqapha okuqhubekayo, kodwa kubalulekile ekwenzeni iphepha elizinzile.
1. Imiphumela Yezinga Eliphansi Lokushaya
Uma ukushaya kuphansi kakhulu, izindonga eziyinhloko nezesibili zemicu aziqhekeki ngokwanele. Ukuvuvukala kwefibre, ukusika, i-fibrillation, kanye nokwakheka kwamafine akuhlangabezani nezidingo zenqubo.
Lokhu kuphumela ekuphumeni kwamanzi ngokushesha okukhulu ngesikhathi sokwakheka, ukubophana kwefayibha okungekuhle, kanye nesakhiwo seshidi esingalingani, okuthinta ukufana, amandla, kanye nokushelela.
2. Imiphumela Yezinga Eliphezulu Lokushaya
Ukwanda kokushaywa kuthuthukisa amandla okubopha kodwa kunciphisa ubude obumaphakathi befayibha kanye nesisindo sewebhu esimanzi.
Ukushaya ngokweqile kusheshisa ukusika i-fiber, ukuvuvukala, kanye ne-fibrillation, okwenza kube nzima ukukhipha amanzi ocingweni, kwandise umugqa wamanzi, futhi kwandise umswakama kuwebhu emanzi.
Umswakama owedlulele ungabangela ukugqokwa noma ukuqhekeka kaningi ngenxa yokucindezela okunganele.
Ukushaya okuphezulu kwandisa nokuncipha kokoma, okuholela ekushintsheni kwezilinganiso zesivinini kuzo zonke izingxenye zomshini, okuthinta ubukhulu beshidi, kanye nokunciphisa amandla nokuqina.
Isilinganiso se-Pulp
Isilinganiso se-pulp sincike ezicini ezifana nezici zezinto zokusetshenziswa, indlela yokudonsa, ukusebenza komshini, kanye nohlobo lwephepha nezidingo zekhwalithi. Ngemva kokunquma izimo zesilinganiso, ukunamathela ngokuqinile enkambisweni kubalulekile ukugwema ukuphazamiseka kokukhiqiza kanye nezindleko ezandayo.
Isilinganiso se-Long vs. Short Fiber
Isilinganiso esifanele sithuthukisa ukubopha kwefayibha, ukufana kweshidi, kanye namandla ngenkathi kunciphisa izindleko futhi kuthuthukisa ukusebenza kahle.
I-fiber ende kakhulu inciphisa amandla okubopha kanye namandla eshidi elimanzi, okubangela ukuqhekeka, kuyilapho i-fiber ende kakhulu ingenakwenzeka ngokwezomnotho.
Izinto Ezibalulekile Okufanele Uzicabangele
I-pulp yotshani yamakhemikhali, enemicu emifushane, izindonga zamaseli ezijiyile, kanye nokuqukethwe okuphezulu kwe-hemicellulose, yenza kube nzima ukwenza iphepha futhi kuthinte ikhwalithi. Ukuze kuncishiswe lezi zinkinga, izinto ze-fiber ende ezisezingeni eliphezulu, njengokotini, ukhuni, noma i-pulp ye-flax, zingaxutshwa, naphezu kwezindleko zazo eziphakeme. Ukuhlanganiswa okufanele kwemicu emide nemifushane kubalulekile ekuqinisekiseni ukwenza iphepha okubushelelezi, ukuhlangabezana nezindinganiso zekhwalithi, kanye nokufeza ukusebenza kahle kwezindleko.
