ʻO ka sodium hydrosulfite a i ʻole ka sodium hydrosulphite, loaʻa ka maʻamau o 85%, 88% 90%. He waiwai weliweli ia, hoʻohana ʻia i ka lole a me nā ʻoihana ʻē aʻe.
E kala mai no ka huikau, aka, he mea okoa ka sodium hydrosulfite mai ka sodium thiosulfate. ʻO ke kumu kemika kūpono no ka sodium hydrosulfite ʻo Na2S2O4. ʻO ka sodium hydrosulfite, i kapa ʻia ʻo sodium dithionite a i ʻole sodium bisulfite, he mea hoʻemi ikaika. Hoʻohana maʻamau ia i nā noi like ʻole, me:
ʻOihana lole: Hoʻohana ʻia ka sodium hydrosulfite ma ke ʻano he mea hoʻomaʻemaʻe i ka ʻoihana lole. He mea maikaʻi loa ia i ka wehe ʻana i ka waihoʻoluʻu mai nā lole a me nā fiber, e like me ka pulupulu, ke olonā, a me ka rayon.
ʻOihana Pulp a me ka pepa: Hoʻohana ʻia ka sodium hydrosulfite e hoʻomaʻemaʻe i ka pulp lāʻau i ka hana ʻana i ka pepa a me nā huahana pepa. Kōkua ia i ka wehe ʻana i ka lignin a me nā mea haumia ʻē aʻe e loaʻa ai kahi huahana hope loa.
