Ukudonsa izinto ngaphambi kokwenza iphepha, okushiya umthelela omkhulu ekusebenzeni okuvamile komshini wephepha kanye nekhwalithi yephepha. Izici ezibalulekile ekushayweni ukugxila kwe-pulp, izinga lokushaya, kanye nesilinganiso se-pulp.
I-Pulp Concentration Measurement
Ukugxila kwe-pulp engazinzile kungaholela kwikhwalithi yephepha engahambisani, futhi kungabangela ukuphuka kwephepha futhi kuphazamise ukwenza iphepha elivamile libe libi nakakhulu. Izici zokungaqini kokugxiliswa kwe-pulp engazinzile zigxila ekushintsheni ukugxila kwe-pulp eluhlaza kanye nezinto ezilahlwayo, ukulungisa ukugxila okwenziwa ngesandla ekubetheni, ukugxilisa nokuhlanganisa, kanye nesistimu yamanzi amhlophe engalingani.
Izinguquko Ekugxilweni Kwe-Raw Pulp
I-pulp elethwa endaweni yokusebenzela ye-pulping iyahlukahluka ekugxiliseni. Ukugxila kokugcina kwe-pulp kuzothinteka uma kwenzeka ukulungiswa okudingekayo kungenziwanga ekugxiliseni.
Ukulungiswa Kokugxila Ekushayeni
Ngesikhathi sokushaywa, i-pulp ibhekana nezinqubo ezifana nokugxilisa ingqondo, ukushaya, nokuxuba, okudinga ukulungiswa kokugxilisa ingqondo. Amanye amasistimu asebenzisapulp densitymeter, kodwa ukulungisa okwenziwa ngesandla kuvame kakhulu. Izinguquko zokugxilisa ingqondo zingase zenzeke ngenxa yokungabi nalwazi komsebenzisi, ukuntula ukukhuthala, noma ukungasebenzi kahle kwemishini.
Izinguquko kuWaste StuffUkugxila
Iphepha eliphukile eligaywe kabusha liqoshwa ku-hydropulper bese ligxiliswa ezingeni elizinzile ngaphambi kokuhlanjululwa ekugxilweni kwenqubo edingekayo. Uma ukugxilwa kwezinto ezingcolile kuhluka kakhulu ngesikhathi sokuphelelwa amanzi emzimbeni kanye nokuhlanjululwa, kungaphazamisa uhlelo lonke lwe-pulp.
Ukungazinzi Ezinhlelweni Zamanzi Amhlophe
Amanzi amhlophe aphinde asetshenziswe ukuhlanjululwa kwe-pulp ukunciphisa ukusetshenziswa kwamanzi nokulahlekelwa kwefayibha. Uma uhlelo lwamanzi amhlophe lungalingani noma ingcindezi nokugeleza kwawo kungazinzi, kuzoba nomthelela ekuhlanjululweni kwe-pulp kanye nokugxila.
Ukushaya iDegree
Izinto ezimbalwa zithonya ukushaya kwe-pulp, njengokucindezela, ukugxilisa ingqondo, izinga lokugeleza, isikhathi, izinga lokushisa, isimo se-blade, nekhono lomsebenzisi. Uma noma yisiphi isinyathelo siphathwa kabi, ikhwalithi yokushaywa kwe-pulp izothinteka. Ukuzinza ukushaya kuyinselele ngaphandle kokuqapha okuqhubekayo, kodwa kubalulekile ekwenzeni iphepha okuzinzile.
1. Imiphumela Yeziqu Zokushaya Okuphansi
Lapho ukushaya kuphansi kakhulu, izindonga eziyinhloko nezesibili zemicu aziphulwa ngokwanele. Ukuvuvukala kwe-fiber, ukusika, i-fibrillation, nokwakhiwa kwezinhlawulo akuhlangabezani nezidingo zenqubo.
Lokhu kubangela ukugeleza kwamanzi okushesha kakhulu ngesikhathi sokwakheka, ukuhlangana okungekuhle kwefayibha, kanye nokwakheka kweshidi elingalingani, kube nomthelela ofanayo, amandla, nokushelela.
2. Imiphumela Yeziqu Eziphakeme Zokushaya
Ukwenyuka kokushaywa kuthuthukisa amandla okubopha kodwa kunciphisa ubude be-fiber obumaphakathi nesisindo sewebhu esimanzi.
Ukushaya ngokweqile kusheshisa ukusikwa kwefayibha, ukuvuvuka, kanye ne-fibrillation, kwenze ukudonsa amanzi ocingweni kube nzima kakhulu, kunwebe umzila wamanzi, nokwandisa umswakama kuwebhu emanzi.
Umswakama owedlulele ungabangela ukufaka imbossing noma amakhefu amaningi ngenxa yokucindezela okunganele kokucindezela.
Ukushaya okuphezulu futhi kwandisa ukuncipha kokuqina, okuholela ekushintsheni kwezilinganiso zesivinini kuzo zonke izingxenye zomshini, kuthinte ubukhulu beshidi, futhi kunciphisa amandla nokuzinza.
Isilinganiso se-Pulp
Isilinganiso se-pulp sincike ezintweni ezifana nezici zempahla eluhlaza, indlela yokudonsa, ukusebenza komshini, nohlobo lwephepha nezidingo zekhwalithi. Ngemva kokunquma izimo zesilinganiso, ukubambelela ngokuqinile kule nqubo kubalulekile ukuze kugwenywe ukuphazamiseka kokukhiqiza kanye nezindleko ezikhulayo.
I-Long vs. I-Short Fiber Ratio
Isilinganiso esifanele sithuthukisa i-fiber bonding, ukufana kweshidi, namandla kuyilapho kunciphisa izindleko futhi kuthuthukisa ukusebenza kahle.
Ifayibha ende encane kakhulu inciphisa amandla okubopha namandla eshidi elimanzi, okubangela ukuphuka, kuyilapho ifayibha ende eningi ayinakwenzeka ngokomnotho.
Ukucatshangelwa Okukhethekile
I-pulp yotshani bekhemikhali, enemicu emifushane, izindonga zamaseli aminyene, nokuqukethwe okuphezulu kwe-hemicellulose, kwenza kube nzima ukwenza iphepha futhi kuthinte ikhwalithi. Ukuze kuncishiswe lezi zinkinga, izinto zekhwalithi ephezulu zefayibha ende, ezifana ukotini, ukhuni, noma i-flax pulp, zingaxutshwa, ngaphandle kwezindleko zazo eziphezulu. Ukuhlanganiswa okufanele kwemicu emide nefushane kuyisihluthulelo sokuqinisekisa ukwenziwa kwephepha okushelelayo, ukuhlangabezana nezindinganiso zekhwalithi, kanye nokufeza izindleko ngendlela efanele.
