Wopanga Mtengo Wabwino Sodium metabisulfite CAS:7681-57-4

Kufotokozera mwachidule:

Sodium metabisulfite : (industrial grade) Sodium metabisulfite (mankhwala chilinganizo: Na2S2O5) amawoneka ngati crystalline woyera kapena ufa wolimba ndi fungo la sulfure pang'ono.Ndi poizoni pokoka mpweya ndipo imatha kukwiyitsa kwambiri khungu ndi minofu.Ikhoza kuwola kuti itulutse utsi wa poizoni wa sulfure ndi sodium pa kutentha kwakukulu.Ikhoza kusakanizidwa ndi madzi kupanga asidi wowononga.Amagwiritsidwa ntchito ngati mankhwala ophera tizilombo, antioxidant, ndi preservative agent komanso ngati reagent ya labotale.Monga chowonjezera cha chakudya, chitha kugwiritsidwa ntchito ngati chosungira komanso antioxidant muzakudya.Itha kugwiritsidwanso ntchito popanga vinyo ndi mowa.Kuphatikiza apo, itha kugwiritsidwa ntchito kuyeretsa zida za homebrew ndi winemaking ngati choyeretsa.Ilinso ndi mitundu yosiyanasiyana ya ntchito zina, mwachitsanzo, kugwiritsidwa ntchito pojambula, monga chothandizira pamapiritsi ena, pochiza madzi, monga gwero la SO2 mu vinyo, ngati bactericide komanso ngati bleaching reagent komanso kuchepetsa wothandizila.Itha kupangidwa kudzera mu evaporation ya sodium bisulfite yomwe yadzaza ndi sulfure dioxide.Tiyenera kuchenjezedwa kuti sodium metabisulfite ali ndi zotsatira pachimake pa kupuma dongosolo, maso ndi khungu.Zikavuta kwambiri, zimatha kuyambitsa kupuma movutikira komanso kuwonongeka kwa m'mapapo komwe kumabweretsa imfa.Chifukwa chake, njira zodzitetezera zogwira ntchito ndi chisamaliro ziyenera kuchitidwa panthawi yantchito.

Kugwiritsa ntchito sodium metabisulfite

Sodium metabisulfite Sodium Metabisulphite, amapanga sodium metabisulfite pochita sulfure dioxide ndi sodium carbonate (soda phulusa), kuyeretsa ndi kuyanika kupanga makhiristo kapena ufa.
Na2CO3 + 2SO2→Na2S2O5 + CO2
Sodium metabisulfite (SMBS, sodium disulfite) ndi woyera, granular olimba mchere mchere.pawiri wopangidwa ndi sodium, sulfure, ndi mpweya, ndipo amagwiritsidwa ntchito m'mafakitale ambiri:
1. m'makampani a zamkati ndi mapepala, m'makampani ojambula zithunzi komanso m'mafakitale ena osiyanasiyana monga bleach kapena dechlorinator.
2.Food Grade sodium metabisulfite ingagwiritsidwe ntchito ngati chakudya chosungira chakudya.Amawonjezedwanso kuzinthu zosiyanasiyana zazakudya ndi vinyo ngati chosungira.
3.Sodium metabisulfite ingagwiritsidwenso ntchito popanga mankhwala ena, Ogwiritsidwa ntchito popanga zoyeretsera, zotsukira, ndi sopo.
4.Imagwiranso ntchito ngati corrosion inhibitor mu mafuta ndi gasi, monga bleaching agent pakupanga kokonati kirimu, monga gwero la sulfure dioxide komanso kuwononga cyanide mu malonda a golide cyanidation.
5.Ndalama za migodi ya golide: Amagwiritsidwa ntchito pakugwa kwa golide kuchokera ku auric acid komanso m'madzi otayira kuchotsa chromium ya hexavaent monga trivalent chromium ndi mvula ikachepetsedwa.
6.Preservative mu njira zopangira zithunzi, zimagwiritsidwa ntchito pojambula.
7.Oxygen scavenge: imasewera ngati scavenger ya okosijeni kuti ichotse mpweya wosungunuka m'madzi onyansa ndi mapaipi.
8.Sodium metabisulfite angagwiritsidwe ntchito ngati initiator pa mtanda kulumikiza polymerization wa polybutadiene mu mitima ya vesicle nembanemba.
9.Ikhoza kuwonjezeredwa ngati antioxidant panthawi yokonza njira zothetsera 6-hydroxydopamine m'maphunziro osiyanasiyana.
10. Dechlorination m'matauni zinyalala, zamkati & mapepala, mphamvu, ndi nsalu nsalu mankhwala mankhwala.
