Imboni yephepha ingumthengi omkhulu wemikhiqizo ye-Sodium Sulfite. I-Sodium Sulfite ingenye yezindlela ezibaluleke kakhulu zokugaya ezimbonini zokwenza iphepha, ikakhulukazi ezifanelekela ukugaya okungewona ukhuni. Izinzuzo zale ndlela yokugaya umbala okhanyayo, ukusetshenziswa okuncane kwe-bleaching agent kanye namanye amakhemikhali, futhi uketshezi olula lungaphinde lusetshenziswe ukuze kukhiqizwe imikhiqizo ehlukahlukene. I-Sodium sulfite anhydrous esetshenziswa ekuphekeni utshani be-alkali wheat, isivuno sokugaya ngokusobala siyathuthuka, i-slurry foam incane, ukuhlunga okuhle, ukuwasha okulula, ukonga amanzi, kunciphisa ukusetshenziswa kwamandla. Izinga lokushaya i-slurry liyancipha, amandla e-fiber amahle, kulula ukwenza iphepha. Umbala we-paste ulula, kulula ukuwuxuba futhi wehlisa inani le-chlorine. Ku-160℃, 20% (ubuningi) I-Sodium Sulfite ibonise umphumela omuhle kakhulu wokuhlukanisa ikhono lokuhlukanisa i-bagasse ne-fiber, futhi izinga lokuhlukanisa lifinyelele ngaphezu kwama-48% ngemva kwemizuzu engama-30.
Ngokuthuthuka okuqhubekayo kwemboni yokwenza amaphepha, ukuvuselelwa kwefayibha yesibili kuyaziswa kakhulu yimboni yokwenza amaphepha, engakwazi nje ukonga izindleko zokwenza amaphepha, kodwa futhi yonge izinsiza zamahlathi, inciphise ukusetshenziswa kwamandla, futhi ivumela ukuvikelwa kwemvelo. I-SSA iyi-ejenti enhle yokususa i-ink, edlala indima ekususeni i-ink ukuvimbela i-pulp ukuthi ingabi phuzi, futhi ukususa i-ink ye-sodium sulphite ngaphansi kwezimo ezibuthakathaka ze-alkaline kungcono kakhulu ekususweni kweyinki. Uma kungekho i-surfactant, hlakazeka ekugxilweni kwe-slurry okungu-10%, ukwengeza i-sodium sulfite engu-2% kunomphumela osobala. I-sodium sulfite engathathi hlangothi isetshenziselwa ukususa i-ink ephephandabeni elidala, futhi inani le-sodium sulfite lingu-3% ~ 4%, elingathola umphumela omuhle wokususa i-ink, linciphise umthwalo wokungcola kwamanzi angcolile, futhi liwusizo ekwelashweni kwamanzi angcolile kamuva.
