Ngwa nke sodium metabisulfite

Sodium metabisulfite Sodium Metabisulphite, na-emepụta sodium metabisulfite site n'imeghachi sulfur dioxide na sodium carbonate (soda ash), na-asachapụ na ihicha ka ọ bụrụ kristal ma ọ bụ ntụ ntụ.
Na2CO3 + 2SO2→Na2S2O5 + CO2
Sodium metabisulfite (SMBS, sodium disulfite) bụ ọcha, nnu sodium siri ike.Ngwakọta inorganic mejupụtara sodium, sọlfọ, na oxygen, ma jiri ya mee ihe n'ọtụtụ ụlọ ọrụ:
1.na ụlọ ọrụ pulp na akwụkwọ, na ụlọ ọrụ foto na ụlọ ọrụ ndị ọzọ dị iche iche dị ka ịcha ọcha ma ọ bụ dechlorinator.
2.Food Grade sodium metabisulfite nwere ike iji dị ka ihe nchekwa nri.A na-agbakwunye ya na ngwaahịa nri na mmanya dị iche iche dị ka ihe nchekwa.
3.Sodium metabisulfite nwekwara ike iji na-emepụta kemịkalụ ndị ọzọ, Ejiri ya na-emepụta ihe na-ehicha ihe, ihe nchacha, na ncha.
4.Ọ na-emekwa dị ka a corrosion inhibitor na mmanụ na gas ụlọ ọrụ, dị ka a ịcha ọcha gị n'ụlọnga na mmepụta nke aki oyibo ude, dị ka isi iyi nke sulfur dioxide na mbibi nke cyanide na azụmahịa gold cyanidation Filiks.
