Yiziphi izici eziyinhloko ezithinta inqwaba yephepha?

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 kuphela 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.
IPHEPHA RAW MATERIAL

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 esiphezulu 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.
uginindela wephepha

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.
