Khokahano ea botsitso
1.Soluble ka metsing, tharollo ea metsi ke alkaline.E qhibiliha hanyenyane joalang.Ha e qhibilihe ka har'a metsi a chlorine le ammonia.Joalo ka ntho e matla e fokotsang, e kopana le sulfur dioxide ho hlahisa sodium bisulfite, 'me e kopana le asiti e matla ho hlahisa letsoai le ts'oanang le ho lokolla sulfur dioxide.
2.E le moemeli oa ho fokotsa matla, ho bonolo ho oxidize tlas'a ketso ea moea o mongobo le khanya ea letsatsi, empa e tsitsitse ho feta sodium sulfite heptahydrate.Ho bola ho etsahala ha ho futhumala.
Tokisetso
Sodium sulfite e ka lokisoa ka ho kenya sulfur dioxide ka har'a tharollo ea sodium hydroxide, 'me ha sulfur dioxide e le ngata, sodium bisulfite e hlahisoa.Kapa ho hlahisa khase ea sulfur dioxide ka har'a tharollo ea sodium carbonate, ho eketsa tharollo ea sodium carbonate ka mor'a ho tlala, ho khantša ho fumana likristale tsa heptahydrate, le ho futhumatsa ho senya metsi ho fumana anhydrous sodium sulfite.
Lisebelisoa
1.Anhydrous sodium sulfite e ka sebelisoa e le fiber stabilizer e entsoeng ke motho, lesela la bleaching agent, moqapi oa lifoto, dae le bleaching deoxidizer, monko o monate le ho fokotsa dae, ho tlosa lignin tsa pampiri, joalo-joalo;
2.E ka sebelisoa e le deoxidizer le bleaching agent indastering ea khatiso le ho daea, 'me e ka sebelisoa ho pheha masela a sa tšoaneng a k'hothone, a ka thibelang oxidation ea lehae ea likhoele tsa k'hothone ho ama matla a fiber le ho ntlafatsa bosoeu ba lihlahisoa tse phehiloeng.
3.E ka boela ea sebelisoa ho etsa cellulose sulfite, sodium thiosulfate, lik'hemik'hale tse phelang, masela a bleached, joalo-joalo, hape e sebelisoa e le moemeli oa ho fokotsa, ho boloka, dechlorination agent, joalo-joalo.
4.E sebelisoa bakeng sa microanalysis le boikemisetso ba tellurium le niobium, ho lokisetsa litharollo tsa nts'etsopele, ho fokotsa moemeli le moqapi indastering ea li-photosensitive.
5.Indasteri ea Organic e sebelisoa e le moemeli oa ho fokotsa tlhahiso ea m-phenylenediamine, 2,5-dichloropyrazolone, anthraquinone -1-sulfonic acid, 1- aminoanthraquinone le sodium aminosalicylate, e ka thibelang oxidation ea lihlahisoa tse felileng ka mokhoa oa ho itšoara. tshebetso.
6.E sebelisoa e le moemeli oa ho fokotsa tlhahiso ea meroho e se nang metsi.
7.Indasteri ea pampiri e sebelisoa e le ho tlosa lignin.
8.Indasteri ea masela e sebelisoa e le mokhoa o tsitsitseng oa likhoele tse entsoeng ke motho.
9.E sebelisoa e le lisebelisoa tse tloaelehileng tsa ho hlahloba le lisebelisoa tsa ho hanyetsa lifoto, indasteri ea elektronike e sebelisetsoa ho etsa li-photosensitive resistance.
10.Indasteri ea ho hloekisa metsi e sebelisetsoa ho tšoara metsi a litšila a electroplating le metsi a nooang.
