Eminyakeni yamuva, abakhiqizi bephepha nabasebenzisi baye banaka kakhulu umthamo wephepha, ngoba umthamo unomthelela omkhulu ezindlekweni nasekusebenzeni komkhiqizo.Ukuminyana kwenqwaba yenqwaba kusho ukuthi ngokuqina okufanayo, isisindo sesisekelo singancishiswa futhi nenani lefiber elisetshenziswayo lingancishiswa, ukuze kufezwe inhloso yokonga izindleko;umthamo omkhulu ungandisa ukuqina kwephepha, okuvumela abashicileli bezincwadi ukuthi bagcine izincwadi eziphelele ezinamakhasi ambalwa Ukuqina kungandisa nokungafihli kwephepha, ukuphrinta nokunciphisa ukuvuza kweyinki yokunyathelisa.Ngakho-ke, i-Takamatsu ibaluleke kakhulu ekulawuleni izindleko zephepha, ukusebenza komkhiqizo kanye nenani elengeziwe lomkhiqizo.
Iyini ivolumu ephezulu?Lena inkomba ebalulekile yephepha, okungukuthi, isilinganiso sesisindo esiyisisekelo kuya ukushuba.Umthamo umelela ukuminyana kwephepha, okungukuthi, ubukhulu be-porosity yephepha.
Izici eziyinhloko ezithinta umthamo wephepha zifaka impahla eluhlaza ye-fiber, uhlobo lwe-pulp, ukusebenza kokushaya, ukugcwalisa, amakhemikhali, ukucindezela, ukomisa, i-calendering, njll.
I-fiber morphology ye-papermaking fiber impahla eluhlaza inethonya elibalulekile kubuningi bephepha.Amafayibha aminyene ane-porosity ephakeme kanye nokuminyana kwenqwaba yephepha, kodwa ukuminyana kwenqwaba akuhlobene kuphela nogqinsi lwefayibha, kodwa futhi kunobudlelwane obubaluleke kakhulu nokuphuka kwefayibha enqubweni yokwenza iphepha.Ekugcineni kuya ngokuthi ingakanani imicu ephukile futhi ikhubazekile.Ngakho-ke, imicu enobubanzi obuncane nodonga oluwugqinsi iqinile, ayichotshozwa kalula, futhi yakha kalula iphepha elinomthamo omkhulu.
Uhlobo lwe-pulp lubuye lube nomthelela omkhulu kumthamo wephepha.Ngokuvamile, i-pulp yesivuno esiphezulu > i-pulp ye-thermomechanical > i-kraft pulp > i-waste pulp.Izinto zokusetshenziswa ezihlukene zinevolumu ehlukene ku-pulp efanayo, ukhuni oluqinile>ukhuni oluthambile.Ubukhulu obuphezulu be-pulp enesivuno esikhulu abufaniswe namanye ama-pulp, ngakho-ke i-pulp enesivuno esiphezulu isetshenziswa kabanzi ukufaka ingxenye ye-bleached kraft hardwood pulp ephepheni lezinga eliphezulu.Ukukhethwa kanye nesilinganiso sezinhlobo ze-pulp kuyisihluthulelo sobuchwepheshe bamanje bokukhiqiza amaphepha axekethile.Ukwengeza i-pulp enesivuno esiphezulu ukuze kuthuthukiswe ukuminyana kwenqwaba yephepha okwamanje kuyindlela ephumelela kakhulu esetshenziswa kakhulu izigayo zephepha.
Ivolumu iyisici esibaluleke kakhulu sephepha.Iphepha lokuminyana ngenqwaba lingagcina ukuqina okudingekile, linciphise ukusetshenziswa kwefayibha, longe izindleko ze-pulp futhi lithuthukise ukuminyana kwenqwaba.Izindlela ezisebenzayo kakhulu okwamanje zihlanganisa ukwengezwa kwe-pulp yesivuno esiphezulu, ukukhethwa kwe-pulp kanye nezinhlelo zenqubo.Ukwenziwa kahle nokuthuthukiswa kwezithasiselo eziningi ngobuningi nakho kuyisiqondiso esibalulekile socwaningo.
