Incazelo Yomkhiqizo:
I-Industrial sodium metabisulfite isetshenziselwa ukuphrinta nokudaya, ukuhlanganiswa kwe-organic, ukuphrinta, ukushuka kwesikhumba, ukwenza imithi kanye neminye imikhakha.
Isicelo:
1. Isetshenziswa njenge-reagent ye-chromatographic, i-preservative kanye ne-ejenti yokunciphisa ku-dyestuff kanye nezimboni zemithi;
2. Isetshenziswa njenge-ejenti yokuhlanza, i-preservative, i-thinning agent, i-antioxidant, ivikela umbala kanye ne-preservative embonini yokudla.
3. Imboni yezemithi yokukhiqiza i-chloroform, i-benzyl utshwala ne-benzaldehyde. Imboni yenjoloba isetshenziswa njenge-coagulant. Imboni yokuphrinta nokudaya isetshenziswa njenge-bleaching kakotini kanye ne-ejenti ye-dechlorinating kanye nensiza yokucwenga ukotini. Imboni yesikhumba yokwelashwa kwesikhumba, ingenza isikhumba sithambile, sigcwele, siqine, singangeni manzi, sigoqeke, singagugi nokunye. Isetshenziswa embonini yamakhemikhali ukukhiqizwa kwe-hydroxyvanillin ne-hydroxylamine hydrochloride. Imboni yezithombe njengonjiniyela, njll.
4. Ukwelashwa kwamanzi: I-sodium metabisulfite iyi-ejenti yokunciphisa, esetshenziswa njengokwelashwa kwamanzi angcolile aqukethe i-chromium ekuhlanzeni indle.
Iphakheji:25 kgs/isikhwama noma njengoba ucela.
Isitoreji:Gcina endaweni engenawo umoya, neyomile.
IsikhuluOkujwayelekile:I-International Standard.
