Characteristics and uses of sodium metabisulfite

[Physicochemical properties]: white or slightly yellow crystalline powder. The relative density is 1.4, soluble in water, the aqueous solution is acidic, soluble in glycerin, and slightly soluble in ethanol. It is easily decomposed by moisture, easily oxidized to sodium sulfate in the exposed air, and heated to 150 ° C to decompose.

[Package]: 25kg / bag; 50kg / bag; 1000kg / bag.

[Main use]: The pharmaceutical industry is used to produce chloroform, phenylpropyl sulfone and benzaldehyde; the rubber industry is used as a coagulant; the printing and dyeing industry is used as a dechlorination agent for cotton bleaching, a cotton scouring aid; and the video industry is used for bleaching agents. , preservatives, bulking agents, antioxidants, color protection agents, preservatives.

[Executive Standard]: HG/T2826-2008

[Main use]: Produce pre-mixed feed, which is generally added to the finished feed. Zinc oxide is a dry powdery zinc source with good stability in feed, no tax, no caking, invariance, easy for feed processing and long-term storage. The effect of vitamins in aged feed is small, and it is more easily absorbed by animals than other zinc sources. , zinc supplementation effect is good.

Feed grade zinc oxide、Sodium metabisulfite、Anhydrous sodium sulfite、Industrial grade zinc oxide.
