Mgwirizano wokhazikika
1.Kusungunuka m'madzi, njira yamadzimadzi ndi yamchere.Zosungunuka pang'ono mu mowa.Insoluble mu madzi klorini ndi ammonia.Monga chochepetsera champhamvu, imalimbana ndi sulfure dioxide kuti ipange sodium bisulfite, ndipo imachita ndi asidi amphamvu kupanga mchere wofananira ndikutulutsa sulfure dioxide.
2.Monga mphamvu yochepetsera mphamvu, imakhala yosavuta oxidize pansi pa machitidwe a mpweya wonyowa ndi kuwala kwa dzuwa, koma imakhala yokhazikika kuposa sodium sulfite heptahydrate.Kuwola kumachitika pamene kutentha.
Kukonzekera
Sodium sulfite ikhoza kukonzedwa poyambitsa sulfure dioxide mu sodium hydroxide solution, ndipo sulfure dioxide ikachuluka, sodium bisulfite imapangidwa.Kapena kuyambitsa mpweya woipa wa sulfure mu sodium carbonate solution, kuwonjezera njira yothetsera sodium carbonate pambuyo pa machulukitsidwe, crystallizing kupeza makhiristo a heptahydrate, ndi kutentha kwa madzi kuti apeze anhydrous sodium sulfite.
Ntchito
1.Anhydrous sodium sulfite angagwiritsidwe ntchito ngati munthu zopangidwa CHIKWANGWANI stabilizer, nsalu bleaching wothandizira, zithunzi mapulogalamu, utoto ndi blekning deoxidizer, mafuta onunkhiritsa ndi utoto kuchepetsa wothandizira, papermaking lignin remover, etc.;
2.Itha kugwiritsidwa ntchito ngati deoxidizer ndi bleaching agent pamakampani osindikizira ndi utoto, ndipo ingagwiritsidwe ntchito pophika nsalu zosiyanasiyana za thonje, zomwe zingalepheretse makutidwe ndi okosijeni am'deralo a ulusi wa thonje kuti asakhudze mphamvu ya fiber ndikuwongolera kuyera kwa zinthu zophika.
3.Itha kugwiritsidwanso ntchito kupanga cellulose sulfite, sodium thiosulfate, mankhwala opangidwa ndi organic, nsalu za bleached, etc., komanso kugwiritsidwa ntchito ngati kuchepetsa wothandizira, kusungirako, dechlorination agent, etc.
4.Imagwiritsidwa ntchito pofufuza ma microanalysis ndi kutsimikiza kwa tellurium ndi niobium, kukonzekera mayankho otukula, kuchepetsa wothandizira komanso wopanga makina opanga zithunzi.
5.Organic makampani ntchito monga kuchepetsa wothandizila kupanga m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone -1- sulfonic asidi, 1- aminoanthraquinone ndi sodium aminosalicylate, amene angalepheretse makutidwe ndi okosijeni wa theka anamaliza mankhwala mu anachita. ndondomeko.
6.Kugwiritsidwa ntchito ngati chochepetsera pakupanga masamba osowa madzi.
Makampani a 7.Paper amagwiritsidwa ntchito ngati chochotsa lignin.
8.Makampani opanga nsalu amagwiritsidwa ntchito ngati chokhazikitsira ulusi wopangidwa ndi anthu.
9.Kugwiritsidwa ntchito ngati wamba kusanthula reagent ndi photosensitive kukana zinthu, makampani amagetsi ntchito kupanga photosensitive kukana.
10.Mafakitale opangira madzi amagwiritsidwa ntchito pochiza madzi onyansa a electroplating ndi madzi akumwa.
