I-Sodium metabisulfite ngumgubo omhlophe okanye otyheli wekristale okanye ikristale encinci enevumba elinamandla le-SO2. Isisombululo sayo samanzi sine-asidi kwaye sikhupha i-SO2 xa sidibana nee-asidi ezinamandla, sivelisa iityuwa ezifanayo. Ukuba ishiywe emoyeni ixesha elide, inyibilika ibe yi-Na2S2O6, ngoko ke le mveliso ayinakugcinwa ixesha elide.
Ukusetyenziswa
Isetyenziswa njengezinto zokugcina ulwelo, ii-agents zokufunxa, kunye nee-agents zokuthulula ekucutshungulweni kokutya. I-Sodium metabisulfite isetyenziswa kumashishini afana nokuprinta nokudaya, ukwenziwa kwezinto eziphilayo, ukuprinta, ukwenza ulusu, amayeza, njl.njl.; I-Sodium metabisulfite isetyenziswa kumashishini eekhemikhali kunye namayeza ukuvelisa umgubo we-inshurensi, i-sulfamethoxazole metamaterial, i-caprolactam, kunye nokucocwa kwe-chloroform, i-phenylpropanoid sulfone, kunye ne-benzaldehyde. Isetyenziswa njengesithako sokulungisa kwishishini leefoto. Ishishini leziqholo lisetyenziselwa ukuvelisa i-vanillin. Isetyenziswa njengesigcini kwishishini lokwenziwa kwebhiya, i-raber coagulant, kunye ne-arhente yokususa i-chlorination kwimpahla yekotoni efunxayo. Izinto eziphilayo ezidityanisiweyo, iidayi, ulusu olusetyenziswa njengee-agents zokunciphisa ulwelo, ezisetyenziswa kumashishini e-electroplating, unyango lwamanzi amdaka kwiindawo zeoyile, kwaye zisetyenziswa njengee-agents zokucubungula izimbiwa kwimigodi.
Ukupakishwa kunye nokuthunyelwa
25KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
