I-Sodium Hydrosulfite 90%
I-Sodium hydrosulfite okanye i-sodium hydrosulfite, inomgangatho we-85%, 88% 90%. Yimpahla eyingozi, esetyenziswa kwimpahla yelaphu nakwezinye iindawo zoshishino.
Ndicela uxolo ngokudideka, kodwa i-sodium hydrosulfite yikhompawundi eyahlukileyo kwi-sodium thiosulfate. Ifomula yekhemikhali echanekileyo ye-sodium hydrosulfite yi-Na2S2O4. I-sodium hydrosulfite, eyaziwa ngokuba yi-sodium dithionite okanye i-sodium bisulfite, yiarhente enamandla yokunciphisa. Isetyenziswa rhoqo kwiindlela ezahlukeneyo, kuquka:
Ishishini lempahla: I-sodium hydrosulfite isetyenziswa njenge-bleaching agent kwishishini lempahla. Isebenza kakuhle kakhulu ekususeni umbala kwimpahla kunye neefayibha, ezifana nekotoni, ilinen, kunye ne-rayon.
Ishishini leepulp nephepha: I-sodium hydrosulfite isetyenziselwa ukunyibilikisa ipulp yomthi ekuveliseni iimveliso zephepha nephepha. Inceda ukususa i-lignin kunye nezinye izinto ezingcolileyo ukuze kufumaneke imveliso yokugqibela eqaqambileyo.

I-Oxalic Acid 99%
I-oxalic acid, ekwaziwa ngokuba yi-ethanedioic acid, sisixhobo esiqinileyo esingenambala esinefomyula yekhemikhali i-C2H2O4. Yikhompawundi yendalo efumaneka kwizityalo ezininzi, kuquka ispinatshi, irhubarb, kunye namandongomane athile.
