Kugadzikana kuwirirana
1.Soluble mumvura, iyo aqueous solution is alkaline.Kunyungudika zvishoma mudoro.Insoluble mumvura chlorine uye ammonia.Semushonga wakasimba wekudzikisa, unopindirana nesarufa dhiokisi kugadzira sodium bisulfite, uye inopindirana neasidhi yakasimba kuburitsa munyu unoenderana nekuburitsa sulfur dioxide.
2.Sesimba rinoderedza simba, zviri nyore kuita oxidize pasi pekuita kwemhepo yakanyorova uye chiedza chezuva, asi yakanyanya kugadzikana kupfuura sodium sulfite heptahydrate.Kuora kunoitika kana kupisa.
Kugadzirira
Sodium sulfite inogona kugadzirwa nekuunza sulfur dioxide mu sodium hydroxide solution, uye kana sulfur dioxide yakawandisa, sodium bisulfite inogadzirwa.Kana kuunza sulfur dioxide gasi mumushonga wesodium carbonate, kuwedzera sodium carbonate solution mushure mekuzadza, crystallizing kuti iwane heptahydrate crystals, uye kudziyisa kuti idehydrate kuti iwane anhydrous sodium sulfite.
Uses
1.Anhydrous sodium sulfite inogona kushandiswa se-man-made fiber stabilizer, fabric bleaching agent, photographic developer, dye uye bleaching deoxidizer, perfume uye dhayi inoderedza agent, papermaking lignin remover, nezvimwewo;
2.Inogona kushandiswa se deoxidizer uye bleaching agent mukudhinda uye dhayi indasitiri, uye inogona kushandiswa pakubika machira akasiyana-siyana ekotoni, ayo anogona kudzivirira oxidation yemunharaunda yekotoni fiber kubva pakukanganisa simba refiber uye kuvandudza kuchena kwezvigadzirwa zvakabikwa.
3.Inogonawo kushandiswa kugadzira cellulose sulfite, sodium thiosulfate, organic chemicals, bleached machira, nezvimwewo, uye inoshandiswawo seanoderedza agent, preservative, dechlorination agent, nezvimwewo.
4.Iyo inoshandiswa kune microanalysis uye kutsunga kwe tellurium uye niobium, kugadzirira kwekugadzirisa mhinduro, kuderedza mumiririri uye mugadziri mune photosensitive industry.
5.Organic industry inoshandiswa seinoderedza mumiririri mukugadzirwa kwem-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone -1-sulfonic acid, 1-aminoanthraquinone uye sodium aminosalicylate, iyo inogona kudzivirira kusvibiswa kwezvigadzirwa zvehafu-yakapera mukupindura. process.
6.Inoshandiswa sekuderedza mumiririri mukugadzirwa kwemiriwo yakasvibiswa.
7.Paper industry inoshandiswa se lignin remover.
8.Indasitiri yemachira inoshandiswa sechigadziko chetambo dzakagadzirwa nevanhu.
9.Inoshandiswa seyakajairwa analytical reagent uye photosensitive resistance material, indasitiri yemagetsi inoshandiswa kugadzira photosensitive resistance.
10.Indasitiri yekuchenesa mvura inoshandiswa kurapa electroplating wastewater uye mvura yekunwa.
