Sodium bisulfite manufacturers should pay attention to sealing knowledge about packaging sodium metabisulfite

1. The packaging bag (barrel) should be painted with a firm logo, including: product name, grade, net weight and name of the manufacturer.

2. Sodium metabisulfite is packed in plastic woven bags or barrels, lined with plastic bags, net weight 25 or 50kg or 1100kg net major packaging bags.

3. It should be stored in a cool, dry warehouse. The package is sealed and should be protected from air oxidation. Pay attention to moisture.

4. Transportation, storage should prevent damage, moisture, and heat deterioration.

5. The storage period of this product is 6 months from the date of production.

6. It is strictly forbidden to store and mix with acids, oxidants and harmful toxic substances.

7. In case of fire, use water and various fire extinguishers to extinguish.

8. Notes on operation: airtight operation and strengthen ventilation. Operators must undergo special training and strictly abide by the operating regulations. It is recommended that operators wear self-priming filter dust masks, chemical safety protective glasses, anti-poison penetration work clothes, and rubber gloves. Handle lightly when handling to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.

Handle with care during loading and unloading to prevent the package from breaking

Sodium metabisulfite properties: white or slightly yellow crystalline powder. The relative density is 1.4. It is soluble in water (54g/100ml water at 20℃; 81.7g/100ml water at 100℃), and the aqueous solution is acidic. Soluble in glycerin, slightly soluble in ethanol. It is easily decomposed by moisture and easily oxidized to sodium sulfate in exposed air. Contact with strong acids releases sulfur dioxide and generates corresponding salts. Heated to 150 ℃ decomposition.

       Uses: used as bleaching agent, mordant, reducing agent, rubber coagulant, also used in organic synthesis, pharmaceuticals and perfumes. Packaging, storage and transportation: Packed in plastic woven bag lined with polyethylene plastic bag, net weight 25kg or 50kg per bag. It should be stored in a cool, dry warehouse. The package is sealed and should be protected from air oxidation. Pay attention to moisture. It should be protected from rain and sunlight during transportation. It is strictly forbidden to store and transport with acids, oxidants and harmful toxic substances. This product should not be stored for a long time. Handle gently during loading and unloading to prevent the package from breaking. In case of fire, use water and various fire extinguishers to put out the fire.
