Sodium Hydrosulfite 90%, Yokonzeka Kutumizidwa ~

Mapulogalamu:
1. Kugwiritsa ntchito sodium hydrosulfite n'kofala kwambiri, makamaka kuphatikiza kuchepetsa utoto, kuyeretsa kuchepetsa, kusindikiza ndi kuchotsa utoto m'makampani opanga nsalu, komanso kuyeretsa silika, ubweya, nayiloni ndi nsalu zina. Popeza sodium hydrosulfite ilibe zitsulo zolemera, mtundu wa nsalu yosungunuka ndi wowala kwambiri ndipo sungathe kutha mosavuta.

2. Sodium hydrosulfite ingagwiritsidwenso ntchito poyeretsa chakudya, monga gelatin, sucrose, zipatso zokhala ndi maswiti, ndi zina zotero, komanso sopo, mafuta a nyama (zomera), nsungwi, kuyeretsa dongo la porcelain.

3. Pa ntchito yopanga zinthu zachilengedwe, sodium hydrosulfite imagwiritsidwa ntchito ngati chochepetsera kapena choyeretsera utoto popanga utoto ndi mankhwala, makamaka ngati choyeretsera utoto popanga mapepala amatabwa.

4. Sodium hydrosulfite imatha kuchepetsa ma ayoni ambiri achitsulo cholemera monga Pb2+, Bi3+, ndi zina zotero kukhala zitsulo pochiza madzi ndi kuchepetsa kuipitsidwa, ndipo ingagwiritsidwenso ntchito kusunga chakudya ndi zipatso.

Yoyaka:Sodium dithionite ndi chinthu choyaka moto kwambiri chikanyowa malinga ndi miyezo ya dziko. Chimachita zinthu mwamphamvu chikakumana ndi madzi, kupanga mpweya woyaka monga hydrogen sulfide ndi sulfur dioxide, ndikutulutsa kutentha kwakukulu. Equation ya reaction ndi: 2Na2S2O4+2H2O+O2=4NaHSO3, ndipo zinthuzo zimachitanso kuti zipange hydrogen sulfide ndi sulfur dioxide. Sodium dithionite ili ndi valence state yapakati ya sulfure, ndipo mankhwala ake ndi osakhazikika. Imasonyeza mphamvu zochepetsera. Ikakumana ndi ma oxidizing acid amphamvu, monga sulfuric acid, perchloric acid, nitric acid, phosphoric acid ndi ma acid ena amphamvu, awiriwa adzakumana ndi redox reaction, ndipo reaction imakhala yamphamvu, kutulutsa kutentha kwakukulu ndi zinthu zoopsa. Equation yake ya reaction ndi: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Kuyaka mwadzidzidzi:Sodium dithionite ili ndi malo oyatsira moto odziyimira pawokha a 250℃. Chifukwa cha malo ake oyatsira moto ochepa, ndi chinthu cholimba choyaka moto chapamwamba kwambiri (malo oyatsira moto nthawi zambiri amakhala pansi pa 300℃, ndipo malo oyatsira moto otsika amakhala pansi pa 100℃). N'zosavuta kuyatsa moto ukakumana ndi kutentha, moto, kukangana ndi kugundana. Liwiro la kuyatsa moto ndi lachangu ndipo chiwopsezo cha moto ndi chachikulu. Mpweya wa hydrogen sulfide womwe umapangidwa panthawi yoyatsira moto ungayambitsenso malo oyatsira moto ambiri, zomwe zimawonjezera chiwopsezo cha moto.

Kuphulika:Sodium dithionite ndi ufa wopepuka wachikasu. Ufawo ndi wosavuta kupanga chisakanizo chophulika mumlengalenga. Kuphulika kwa fumbi kumachitika mukakumana ndi gwero la moto. Chisakanizo cha sodium dithionite ndi ma oxidants ambiri, monga ma chlorate, nitrates, perchlorate, kapena permanganate, chimaphulika. Ngakhale pakakhala madzi, chimaphulika pambuyo pa kukangana pang'ono kapena kugundana, makamaka kutentha kukachepa, mpweya woyaka womwe umapangidwa pambuyo poti wafika pamlingo wophulika, ndiye kuti chiopsezo chake cha kuphulika chimakhala chachikulu.
