Versatile Reducing Agent for Industrial Applications

Sodium Hydrosulphite is essential in decolorizing, bleaching, and reducing processes across various sectors. With its fine powder characteristics and high purity, it meets stringent industry standards. From treating wastewater to preparing fresh textiles and papers, this chemical ensures efficient results wherever a strong reducing agent is required.

Safe Storage and Handling Considerations

For optimal shelf life and quality, Sodium Hydrosulphite must be stored in a cool, dry, and well-ventilated area, away from acids and moisture. Avoid exposing the product to high temperatures above 30C. The packaging is tailored to maintain stability, preventing premature decomposition and preserving integrity for up to 12 months.

FAQs of Sodium Hydrosulphite:

Q: How should Sodium Hydrosulphite be stored to maintain stability and shelf life?

A: Store Sodium Hydrosulphite in a cool, dry, and well-ventilated environment away from acids and moisture. Always use original, tightly sealed packaging, such as multilayer kraft paper bags with an inner plastic lining. Proper storage protects against decomposition and ensures a shelf life of up to 12 months.

Q: What are the main industrial applications of Sodium Hydrosulphite?

A: Sodium Hydrosulphite is widely used as a reducing agent, bleaching agent, and de-colorizing agent in the textile, paper, water treatment, leather, and chemical synthesis industries. Its effectiveness in removing color and reducing compounds makes it a preferred choice for these processes.

Q: When does Sodium Hydrosulphite become hazardous during handling or storage?

A: Sodium Hydrosulphite becomes hazardous if exposed to moisture, acids, oxidizers, or high temperatures above 30C, as these conditions trigger decomposition. It is classified as Class 4.2 (spontaneously combustible material), so compliance with handling and storage guidelines is crucial to minimize risks.

Q: Where is Sodium Hydrosulphite produced and supplied from?

A: The product is manufactured in China and distributed internationally by exporters, importers, and suppliers, including those based in India. It is available in industrial grade for various commercial uses.

Q: What is the process of packaging Sodium Hydrosulphite for shipment?

A: Sodium Hydrosulphite is typically packed in 25 kg multilayer kraft paper bags with an inner plastic lining to protect it from moisture and contamination. Packaging can be customized according to customer requirements to ensure safe transportation and storage.

Q: How is Sodium Hydrosulphite beneficial in textile and paper industries?

A: In the textile and paper sectors, Sodium Hydrosulphite acts as a potent bleaching agent and reducing agent. It brightens fabrics, removes unwanted colors, and ensures products have a clean appearance. Its efficiency in decolorizing and purifying processes contributes to higher quality outputs.

Q: What precautions should be taken while using Sodium Hydrosulphite?

A: Users should avoid contact with acids, moisture, and oxidizing substances. Protective equipment is recommended during handling to prevent exposure. Its best to operate in well-ventilated areas and to keep the product away from heat sources to minimize hazard risks.
