In addition to being used as a food preservative and bleaching agent, copper sulfate is widely used in other industries. Copper sulfate can also be used in printing and dyeing, organic synthesis, printing, leather making, and pharmaceutical industries. Copper sulfate products are widely used, and the purchase amount of each batch of enterprises is also large, but here we, as a professional copper sulfate manufacturer, remind you that copper sulfate products cannot be stored for a long time.
Why can't copper sulfate products be kept for a long time?
Copper sulfate products are white or yellow crystalline powder or small crystals, with a strong SO2 odor, specific gravity 1.4, soluble in water, and the aqueous solution is acidic. When contacted with strong acids, SO2 will be released and corresponding salts will be generated. It is easy to oxidize, so the product cannot be stored for a long time. Above 150°C, SO2 is decomposed.
Copper sulfate products should be stored in a cool, dry warehouse. The package should be sealed and protected from air oxidation and moisture. Transportation and storage should prevent damage, moisture, and heat deterioration. The storage period of this product is 6 months from the date of production. Storage and transportation with acids, oxidants, and harmful and toxic substances are strictly prohibited.
