Umphumela we-fiber morphology ku-pulp izakhiwo kanye nekhwalithi

Embonini yephepha, i-fiber morphology ingenye yezinto ezibalulekile ezinquma izakhiwo ze-pulp kanye nekhwalithi yokugcina yephepha. I-fiber morphology ihlanganisa ubude obumaphakathi bamafayibha, isilinganiso sokujiya kodonga lwamaseli efayibha kuya kububanzi beseli (okubizwa ngokuthi isilinganiso sodonga ukuya emgodini), kanye nenani lama-heterocyte angewona ama-fibrous kanye nezinqwaba zefiber ku-pulp. Lezi zici ziyasebenzisana, futhi zithinta ngokuhlanganyela amandla esibopho se-pulp, ukusebenza kahle kokuphelelwa amanzi emzimbeni, ukusebenza kokukopisha, kanye namandla, ukuqina kanye nekhwalithi iyonke yephepha.

1) I-avareji yobude befayibha
Isilinganiso sobude bemicu ingenye yezinkomba ezibalulekile zekhwalithi ye-pulp. Imicu emide yenza amaketanga enethiwekhi amade ku-pulp, esiza ukuthuthukisa amandla esibopho kanye nezakhiwo eziqinile zephepha. Lapho ubude obujwayelekile bezintambo bukhula, inani lamaphuzu ahlanganisiwe phakathi kwezintambo liyakhula, okuvumela iphepha ukuthi lihlakaze kangcono ukucindezeleka lapho lingaphansi kwamandla angaphandle, ngaleyo ndlela lithuthukise amandla nokuqina kwephepha. Ngakho-ke, ukusetshenziswa kwemicu yobude obujwayelekile ende, njenge-spruce coniferous pulp noma ukotini nelineni, kungaveza amandla aphakeme, ukuqina okungcono kwephepha, lawa maphepha afaneleka kakhulu ukusetshenziswa esidingweni sezakhiwo eziphakeme zomzimba zomcimbi, njengezinto zokupakisha, iphepha lokuphrinta nokunye.
2) Isilinganiso sokujiya kwe-fiber cell wall kuya ku-diameter ye-cell cavity (i-wall-to-cavity ratio)
I-wall-to-cavity ratio ingenye into ebalulekile ethinta izakhiwo ze-pulp. I-Lower wall-to-cavity ratio isho ukuthi udonga lwe-fiber cell luncane futhi i-cavity yeseli inkulu, ukuze imicu yenqubo ye-pulping kanye ne-papermaking ibe lula ukumunca amanzi futhi ithambe, evumela ukucolisiswa kwemicu, ukuhlakazeka. nokuhlangana. Ngesikhathi esifanayo, imicu emincane enezindonga ezincane inikeza ukuguquguquka okungcono nokugoqeka lapho wenza iphepha, okwenza iphepha lifaneleke kakhulu ekucubunguleni nasekubumbeni izinqubo. Ngokuphambene, amafayibha anezilinganiso eziphakeme zodonga-to-cavity angaholela ephepheni eliqinile, eliphukayo, elingahambisani nokucubungula nokusetshenziswa okulandelayo.
3) Okuqukethwe kwama-heterocyte angewona ama-fibrous nama-fiber bundles
Amaseli angewona ama-fibrous nama-fiber bundles ku-pulp yizici ezingezinhle ezithinta ikhwalithi yephepha. Lokhu kungcola ngeke kunciphise kuphela ukuhlanzeka nokufana kwe-pulp, kodwa futhi nenqubo yokwenza iphepha ukwenza amafindo namaphutha, okuthinta ukushelela namandla ephepha. Ama-heterocyte angewona ama-fibrous angase aqhamuke ezingxenyeni ezingezona i-fibrous ezifana namagxolo, i-resin nezinsini endaweni eluhlaza, kuyilapho ama-fiber bundles ama-fiber aggregates akhiwe ngenxa yokwehluleka kwempahla eluhlaza ukuhlukana ngokwanele phakathi nenqubo yokulungisa. Ngakho-ke, lokhu kungcola kufanele kususwe ngangokunokwenzeka ngesikhathi senqubo yokudonsa ukuze kuthuthukiswe izinga le-pulp kanye nesivuno sephepha.
