Stability kev sib raug zoo
1.Soluble nyob rau hauv dej, cov aqueous tov yog alkaline.Me ntsis soluble hauv cawv.Insoluble hauv kua chlorine thiab ammonia.Raws li ib tug muaj zog txo tus neeg sawv cev, nws reacts nrog sulfur dioxide los tsim sodium bisulfite, thiab reacts nrog muaj zog acid los tsim cov ntsev sib tov thiab tso sulfur dioxide.
2.Ua tus neeg sawv cev muaj zog, nws yooj yim rau oxidize nyob rau hauv qhov kev txiav txim ntawm huab cua thiab hnub ci, tab sis nws yog ruaj khov dua sodium sulfite heptahydrate.Decomposition tshwm sim thaum rhuab.
Kev npaj
Sodium sulfite tuaj yeem npaj tau los ntawm kev qhia cov sulfur dioxide rau hauv cov tshuaj sodium hydroxide, thiab thaum sulfur dioxide ntau dhau, sodium bisulfite tsim tawm.Los yog qhia cov roj sulfur dioxide rau hauv cov tshuaj sodium carbonate, ntxiv cov tshuaj sodium carbonate tom qab saturation, crystallizing kom tau heptahydrate crystals, thiab cua sov kom lub cev qhuav dej kom tau cov sodium sulfite anhydrous.
Siv
1.Anhydrous sodium sulfite tuaj yeem siv los ua tus txiv neej ua fiber ntau stabilizer, ntaub bleaching tus neeg saib xyuas, tus tsim duab, dye thiab bleaching deoxidizer, naj hoom thiab dye txo tus neeg sawv cev, papermaking lignin remover, thiab lwm yam.
2.Nws tuaj yeem siv los ua deoxidizer thiab tshuaj dawb hauv kev lag luam luam ntawv thiab dyeing, thiab tuaj yeem siv rau hauv kev ua noj ntawm ntau yam paj rwb fabrics, uas tuaj yeem tiv thaiv oxidation hauv zos ntawm paj rwb fibers los ntawm kev cuam tshuam fiber ntau thiab txhim kho cov xim dawb ntawm cov khoom siav.
3.Nws kuj tseem siv tau los ua cellulose sulfite, sodium thiosulfate, organic chemicals, bleached fabrics, thiab lwm yam, thiab kuj siv tau los ua tus neeg saib xyuas txo, preservative, dechlorination agent, thiab lwm yam.
4.Nws yog siv rau microanalysis thiab kev txiav txim siab ntawm tellurium thiab niobium, kev npaj cov kev daws teeb meem, txo tus neeg sawv cev thiab tsim tawm hauv kev lag luam photosensitive.
5.Organic kev lag luam yog siv los txo tus neeg sawv cev hauv kev tsim cov m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone -1- sulfonic acid, 1- aminoanthraquinone thiab sodium aminosalicylate, uas tuaj yeem tiv thaiv oxidation ntawm semi-tiav khoom hauv cov tshuaj tiv thaiv. txheej txheem.
6.Siv los txo tus neeg sawv cev hauv kev tsim cov zaub dehydrated.
7.Paper kev lag luam yog siv lignin tshem tawm.
8.Qhov kev lag luam textile yog siv los ua tus stabilizer rau cov txiv neej ua fibers.
9.Siv raws li kev tshuaj ntsuam reagent thiab cov khoom siv photosensitive, kev lag luam hluav taws xob yog siv los tsim cov duab tsis zoo.
10.Qhov kev lag luam kho dej yog siv los kho cov dej khib nyiab electroplating thiab dej haus.
