Ishishini lephepha lelona lithenga kakhulu iimveliso zeSodium Sulfite. ISodium Sulfite yenye yezona ndlela zibalulekileyo zokucoca kwishishini lokwenza iphepha, ngakumbi ezifanelekileyo kwi-pulping engeyiyo imithi. Iingenelo zale ndlela yokucoca kukukhanya okukhanyayo, ukusetyenziswa kancinci kwe-bleaching agent kunye nezinye iikhemikhali, kwaye ulwelo olulahlwayo lunokuphinda lusetyenziswe ukuvelisa iintlobo ngeentlobo zeemveliso ezishiyekileyo. I-Sodium sulfite anhydrous esetyenziswa ekuphekeni i-alkali wheat straw, isivuno sokucoca siphucukile ngokucacileyo, i-slurry foam incinci, ukuhluzwa kakuhle, ukuhlamba okulula, ukonga amanzi, ukunciphisa ukusetyenziswa kwamandla. Iqondo lokubetha i-slurry liyancipha, amandla e-fiber alungile, kulula ukwenza iphepha. Umbala we-paste ulula, kulula ukuwuxuba kwaye unciphisa ubungakanani be-chlorine. Kwi-160℃, i-20% (ubunzima) iSodium Sulfite ibonakalise impembelelo entle yokucoca kwisakhono sokwahlula i-bagasse kunye ne-fiber, kwaye izinga lokucoca lifikelele kwi-48% emva kwemizuzu engama-30.
Ngophuhliso oluqhubekayo lweshishini lokwenza amaphepha, ukuphinda kusetyenziswe ifayibha yesibini kuyaxatyiswa kakhulu lishishini lokwenza amaphepha, elingenakukwazi nje ukonga iindleko zokwenza amaphepha, kodwa likwanokonga izixhobo zamahlathi, linciphise ukusetyenziswa kwamandla, kwaye lilungele ukukhuselwa kwendalo. I-SSA sisithako esilungileyo sokususa i-ink, esidlala indima ekususeni i-ink ukuthintela i-pulp ukuba ingabi tyheli, kwaye ukususa i-ink ye-sodium sulphite phantsi kweemeko ezibuthathaka ze-alkaline kulungile ngakumbi ekususeni i-inki. Ukuba akukho surfactant, yinyibilike kwi-10% ye-slurry concentration, ukongeza i-2% ye-sodium sulfite kunempembelelo ecacileyo. I-sodium sulfite engathathi cala isetyenziselwa ukususa i-ink kwiphephandaba elidala, kwaye ubungakanani be-sodium sulfite yi-3% ~ 4%, enokufumana impembelelo entle yokususa i-ink, inciphise umthwalo wongcoliseko lwamanzi amdaka, kwaye iluncedo ekunyangweni kwamanzi amdaka kamva.
