Sodium Hydrosulfite 90%, Yakagadzirira Kutumirwa ~

Applications:
1. Kushandiswa kwe sodium hydrosulfite yakakura kwazvo, kunyanya kusanganisira kuderedza dhayi, kuderedza kucheneswa, kudhinda uye decolorization mumhizha yemucheka, pamwe nekusvibiswa kwesilika, mvere, nylon nemamwe machira. Sezvo sodium hydrosulfite isina simbi inorema, ruvara rwemucheka wakacheneswa wakajeka kwazvo uye hausi nyore kupera.

2. Sodium hydrosulfite inogonawo kushandiswa pakudya bleaching, zvakadai gelatin, sucrose, candied michero, nezvimwewo, uyewo sipo, mhuka (chirimwa) mafuta, bamboo, porcelain ivhu bleaching.

3. Mumunda we organic synthesis, sodium hydrosulfite inoshandiswa sechinhu chinoderedza kana kuti bleaching agent mukugadzirwa kwedhayi nemishonga, kunyanya se bleaching agent yehuni pulp papermaking.

4. Sodium hydrosulfite inogona kuderedza akawanda heavy metal ions akadai sePb2 +, Bi3 +, nezvimwewo kune simbi mukurapa kwemvura uye kutonga kusvibiswa, uye inogonawo kushandiswa kuchengetedza zvokudya nemichero.

Danger
Inobvira moto:Sodium dithionite chinhu chekutanga chinobatidza moto kana chanyorova zvinoenderana nenyika. Ichaita zvechisimba kana ikasangana nemvura, ichibudisa magasi anopisa akadai sehydrogen sulfide uye sulfur dioxide, uye kusunungura huwandu hwekupisa. Mhedzisiro equation ndeiyi: 2Na2S2O4+2H2O+O2=4NaHSO3, uye zvigadzirwa zvinowedzera kuita kubudisa hydrogen sulfide uye sulfur dioxide. Sodium dithionite ine yepakati valence mamiriro esarufa, uye makemikari ayo haana kugadzikana. Inoratidza yakasimba kuderedza zvinhu. Apo inosangana neakasimba oxidizing acids, yakadai se sulfuric acid, perchloric acid, nitric acid, phosphoric acid uye mamwe maasidhi akasimba, maviri acho achaita redox reaction, uye maitiro acho ane chisimba, achibudisa huwandu hwakawanda hwekupisa uye chepfu. Maitiro ayo equation ndeiyi: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Kupisa kwepakarepo:Sodium dithionite ine nzvimbo inobvira yekupisa ye250 ℃. Nekuda kwekudzikira kwayo kwekubatidza, ndeyekutanga-kirasi inobatidza yakasimba (iyo ignition point inowanzo iri pazasi 300 ℃, uye iyo flash point yekunyungudika yakaderera iri pazasi pe100 ℃). Zviri nyore kupisa kana waiswa mukupisa, moto, kupokana uye kukanganisa. Iyo yekupisa inokurumidza uye njodzi yemoto yakakwirira. Iyo gasi hydrogen sulfide gasi inogadzirwa panguva yekupisa inogona kukonzera hombe nzvimbo yekupisa, ichiwedzera njodzi yayo yemoto.

Kuputika:Sodium dithionite chinhu cheyero chehupfu. Hupfu hwehupfu huri nyore kugadzira musanganiswa unoputika mumhepo. Kuputika kweguruva kunoitika kana wasangana nechitubu chemoto. Musanganiswa we sodium dithionite uye yakawanda oxidants, yakadai seklorate, nitrate, perhlorates, kana permanganate, inoputika. Kunyangwe pamberi pemvura, inoputika mushure mekuputika kuduku kana kukanganisa, kunyanya mushure mekupisa kwekupisa, gasi rinopisa rinogadzirwa mushure mokunge maitiro asvika pamuganhu wekuputika, ipapo njodzi yekuputika kwayo yakakura.
