I-Sodium metabisulfite iyimpuphu emhlophe noma ephuzi ekristalu noma ikristalu encane enephunga elinamandla le-SO2. Isixazululo sayo samanzi sine-asidi futhi sikhipha i-SO2 uma sithintana nama-asidi aqinile, sikhiqiza usawoti ohambisanayo. Uma ishiywe emoyeni isikhathi eside, i-oxidize ibe yi-Na2S2O6, ngakho-ke lo mkhiqizo awukwazi ukugcinwa isikhathi eside.
Ukusetshenziswa
Isetshenziswa njengezilondolozi, izinto zokuhlanza, kanye nezinto zokukhulula ekucubungulweni kokudla. I-Sodium metabisulfite isetshenziswa ezimbonini ezifana nokuphrinta nokudaya, ukwenziwa kwezinto eziphilayo, ukuphrinta, ukwenza isikhumba, imithi, njll; I-Sodium metabisulfite isetshenziswa ezimbonini zamakhemikhali nezokwelapha ekukhiqizeni i-inshuwalense powder, i-sulfamethoxazole metamaterial, i-caprolactam, kanye nokuhlanzwa kwe-chloroform, i-phenylpropanoid sulfone, kanye ne-benzaldehyde. Isetshenziswa njengesithako sokulungisa embonini yezithombe. Imboni yezinongo isetshenziselwa ukukhiqiza i-vanillin. Isetshenziswa njengesilondolozi embonini yokwenza ubhiya, i-raber coagulant, kanye ne-dechlorination agent yezindwangu zikakotini ezihlanjululwe. Izinto eziphilayo ezihlanganisiwe, udayi, isikhumba esisetshenziswa njengezinto zokunciphisa, esisetshenziswa embonini ye-electroplating, ukwelashwa kwamanzi amdaka emasimini kawoyela, futhi sisetshenziswa njengezinto zokucubungula amaminerali ezimayini.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
