Hoʻopili kūpaʻa
1.Soluble i ka wai, he alkaline ka wai.Hiki ke hoʻoheheʻe ʻia i ka waiʻona.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka chlorine wai a me ka amonia.Ma ke ʻano he mea hoʻohaʻahaʻa ikaika, hana ia me ka sulfur dioxide e hoʻohua i ka sodium bisulfite, a hana pū me ka waikawa ikaika e hana i ka paʻakai like a hoʻokuʻu i ka sulfur dioxide.
2.Ma keʻano he mea hoʻohaʻahaʻa ikaika, ua maʻalahi ka oxidize ma lalo o ka hana o ka ea humid a me ka lā, akā,ʻoi aku ka paʻa ma mua o ka sodium sulfite heptahydrate.Hiki ke decomposition ke wela.
Hoʻomākaukau
Hiki ke hoʻomākaukau ʻia ka sodium sulfite ma ka hoʻokomo ʻana i ka sulfur dioxide i loko o ka solution sodium hydroxide, a i ka nui o ka sulfur dioxide, hana ʻia ka sodium bisulfite.A i ʻole hoʻokomo ʻana i ke kinoea sulfur dioxide i loko o ka solution sodium carbonate, e hoʻohui i ka solution sodium carbonate ma hope o ka saturation, crystallizing no ka loaʻa ʻana o nā kristal heptahydrate, a me ka hoʻomehana ʻana e maloʻo no ka loaʻa ʻana o ka sodium sulfite anhydrous.
Hoʻohana
1.Anhydrous sodium sulfite hiki ke hoʻohana ʻia e like me ke kanaka-made fiber stabilizer, fabric bleaching agent, photographic developer, dye and bleaching deoxidizer, ka meaʻala a me ka mea hoʻoheheʻe dye, ka mea hoʻohemo pepa lignin, etc.;
2. Hiki ke hoʻohana ʻia ma ke ʻano he deoxidizer a me ka bleaching agent i ka paʻi ʻana a me ka ʻoihana pena, a hiki ke hoʻohana ʻia i ka kuke ʻana i nā lole pulupulu like ʻole, hiki ke pale i ka oxidation kūloko o nā pulu pulupulu mai ka hoʻopili ʻana i ka ikaika fiber a hoʻomaikaʻi i ke keʻokeʻo o nā huahana i kuke ʻia.
3. Hiki ke hoʻohana ʻia e hana i ka cellulose sulfite, sodium thiosulfate, nā kemika organik, nā lole bleached, a me nā mea ʻē aʻe, a hoʻohana ʻia hoʻi e like me ka mea hoʻohaʻahaʻa, preservative, dechlorination agent, etc.
4. Hoʻohana ʻia ia no ka microanalysis a me ka hoʻoholo ʻana o tellurium a me niobium, hoʻomākaukau i nā hoʻonā mea hoʻomohala, hoʻemi i ka mea hana a me ka mea hoʻomohala i ka ʻoihana photosensitive.
Hoʻohana ʻia ka ʻoihana Organic e like me ka mea hoʻemi i ka hana ʻana o ka m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone -1- sulfonic acid, 1- aminoanthraquinone a me ka sodium aminosalicylate, hiki ke pale i ka oxidation o nā huahana semi-finished i ka hopena. kaʻina hana.
6.Hoʻohanaʻia ma keʻano he mea hoʻohaʻahaʻa i ka hanaʻana i nā mea kanu maloʻo.
7. Hoʻohana ʻia ka ʻoihana pepa e like me ka lignin remover.
8. Hoʻohana ʻia ka ʻoihana textile ma ke ʻano he stabilizer no nā fibers i hana ʻia e ke kanaka.
9. Hoʻohana ʻia e like me ka reagent analytical maʻamau a me nā mea kūʻē photosensitive, hoʻohana ʻia ka ʻoihana uila e hana i ke kūʻē photosensitive.
10. Hoʻohana ʻia ka ʻoihana hoʻomaʻamaʻa wai e mālama i ka electroplating wastewater a me ka wai inu.
