Eminyakeni yakamuva,abakhiqizi bamaphephafuthi abasebenzisi banake kakhulu inqwaba yephepha, ngoba inqwaba inomthelela omkhulu ezindlekweni nasekusebenzeni komkhiqizo.Ubuningi obuphezulu busho ukuthi ngokuqina okufanayo, isisindo sesisekelo singancishiswa, futhi inani le-fiber elisetshenzisiwe lingancishiswa ukuze kuzuzwe ukonga izindleko;inqwaba ingakhuphula ukuqina kwephepha, okuvumela abashicileli bezincwadi ukuthi bagcine ukujiya okugcwele kwencwadi enamakhasi ambalwa, futhi kungandisa ukufiphala kwephepha, ukuphrinta, nokunciphisa ukukhishwa kwe-inki yokunyathelisa.Ngakho-ke, inqwaba ibaluleke kakhulu ekulawuleni izindleko zephepha, ukusebenza komkhiqizo kanye nenani elengeziwe lemikhiqizo.
Kuyini ubuningi obuphezulu?Lesi yinkomba ebalulekile yephepha, okuyisilinganiso sesisindo esiyisisekelo kuya ukushuba.Ubuningi bubonisa ukuminyana kwephepha, okungukuthi, ubukhulu be-porosity yephepha.
Izici eziyinhloko ezithinta inqwaba yephepha zifaka izinto zokusetshenziswa kwe-papermaking fiber, uhlobo lwe-pulp, ukusebenza kokushaya, izigcwalisi, amakhemikhali, ukucindezela, ukomisa, ukufakwa kwekhalenda, njll.
I-fiber morphology ye-papermaking fiber impahla eluhlaza inethonya elibalulekile ebuningini bephepha.Imicu ewugqinsi ine-porosity ephakeme kanye nenqwaba yephepha ephakeme, kodwa inqwaba ayihlobene nje nogqinsi lwefayibha, kodwa futhi inobudlelwane obubaluleke kakhulu nokuchotshozwa kwemicu ngesikhathi sokwenza iphepha.Ekugcineni kuncike ezingeni lokuchotshozwa kanye nokuguqulwa kwemicu.Ngakho-ke, imicu enobubanzi obuncane nezindonga eziwugqinsi iqinile, akulula ukuyichoboza, futhi kulula ukwenza iphepha lenqwaba.
Uhlobo lwe-pulp lubuye lube nethonya elikhulu kubuningi bephepha.Ngokuvamile, i-high-yield pulp>i-thermomechanical pulp>i-kraft pulp>i-waste pulp.Izinto zokusetshenziswa ezihlukene zinenqwaba ehlukene ku-pulp efanayo, ukhuni oluqinile > ukhuni oluthambile.Iinqwaba ephezuluye-pulp enesivuno esikhulu ngokwayo ayinakuqhathaniswa namanye ama-pulp, ngakho-ke i-pulp enesivuno esiphezulu isetshenziswa kabanzi ukufaka ingxenye ye-bleached kraft hardwood pulp ephepheni eliphezulu.Ukukhethwa kanye nesilinganiso sezinhlobo ze-pulp kuyisihluthulelo senqubo yamanje yokukhiqiza iphepha lenqwaba.Ukwengeza i-pulp yesivuno esiphezulu ukuze kuthuthukiswe inqwaba yephepha okwamanje kuyindlela ephumelela kakhulu esetshenziswa kakhulu izigayo zephepha.
Ubuningi buyinto ebaluleke kakhulu yephepha.Inqwaba ephezuluiphepha lingagcina ukuqina okudingekile, linciphise ukusetshenziswa kwefayibha, longe izindleko ze-pulp, futhi lithuthukise inqwaba.Izindlela ezingenzeka kakhulu okwamanje zihlanganisa ukungeza i-pulp enesivuno esikhulu, ukukhethwa kwe-pulp kanye nezinhlelo zenqubo.Ukwenziwa ngcono nokuthuthukiswa kwezithasiselo eziningi ngobuningi nakho kuyisiqondiso esibalulekile socwaningo.
