Sodium Hydrosulfite 90%, Yokonzeka Kutumiza ~

Mapulogalamu:
1. Kugwiritsiridwa ntchito kwa sodium hydrosulfite ndi kwakukulu kwambiri, makamaka kuphatikizapo kuchepetsa utoto, kuchepetsa kuyeretsa, kusindikiza ndi kutulutsa utoto m'makampani a nsalu, komanso kupukuta kwa silika, ubweya, nayiloni ndi nsalu zina. Popeza sodium hydrosulfite ilibe zitsulo zolemera, mtundu wa nsalu yowutsa umakhala wowala kwambiri komanso wosavuta kuzimiririka.

2. Sodium hydrosulfite ingagwiritsidwenso ntchito poyeretsa chakudya, monga gelatin, sucrose, zipatso za candied, etc., komanso sopo, nyama (chomera) mafuta, nsungwi, bleaching dongo ladongo.

3. M'munda wa organic synthesis, sodium hydrosulfite imagwiritsidwa ntchito ngati chochepetsera kapena bleaching agent popanga utoto ndi mankhwala, makamaka ngati bleaching agent for wood zamkati papermaking.

4. Sodium hydrosulfite ikhoza kuchepetsa ayoni ambiri olemera kwambiri monga Pb2+, Bi3+, ndi zina zotero.

Zoyaka:Sodium dithionite ndi chinthu choyambirira choyaka moto chikanyowa molingana ndi miyezo ya dziko. Idzachita mwachiwawa ikakumana ndi madzi, kutulutsa mpweya woyaka monga hydrogen sulfide ndi sulfure dioxide, ndi kutulutsa kutentha kwakukulu. Equation yake ndi: 2Na2S2O4+2H2O+O2=4NaHSO3, ndipo zinthuzo zimachitanso kupanga hydrogen sulfide ndi sulfure dioxide. Sodium dithionite ili ndi gawo lapakati la sulfure, ndipo mankhwala ake ndi osakhazikika. Zimasonyeza amphamvu kuchepetsa katundu. Akakumana ndi asidi oxidizing amphamvu, monga sulfuric acid, perchloric acid, nitric acid, phosphoric acid ndi asidi ena amphamvu, awiriwo amakumana ndi redox reaction, ndipo zomwe zimachitika zimakhala zachiwawa, kutulutsa kutentha kwakukulu ndi zinthu zoopsa. Equation yake ndi: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Kuyaka modzidzimutsa:Sodium dithionite ili ndi malo oyatsira mowiriza a 250 ℃. Chifukwa cha malo ake oyatsira otsika, ndi olimba omwe amatha kuyaka (malo oyatsira nthawi zambiri amakhala pansi pa 300 ℃, ndipo kung'anima komwe kumasungunuka kumakhala pansi pa 100 ℃). Ndiosavuta kuyaka ikakhudzidwa ndi kutentha, moto, kukangana ndi kukhudzidwa. Liwiro la kuyaka liri mofulumira ndipo ngozi ya moto ndi yaikulu. Mpweya wa hydrogen sulfide wopangidwa panthawi yakuyaka ungayambitsenso malo oyaka kwambiri, kuonjezera ngozi yake yamoto.

Kuphulika:Sodium dithionite ndi chinthu chopepuka chachikasu cha ufa. Mankhwala a ufa ndi osavuta kupanga chisakanizo chophulika mumlengalenga. Kuphulika kwa fumbi kumachitika mukakumana ndi gwero lamoto. Kusakaniza kwa sodium dithionite ndi zowonjezera zowonjezera, monga klorate, nitrates, perhlorates, kapena permanganate, zimaphulika. Ngakhale pamaso pa madzi, amaphulika pambuyo pa kukangana pang'ono kapena kukhudzidwa, makamaka pambuyo pakuwola kwa kutentha, mpweya woyaka moto wopangidwa pambuyo pa zomwe zimafika pamtunda wa kuphulika, ndiye kuti kuphulika kwake kumakhala kwakukulu.
