主要应用

 

Pharmaceuticals, reducing agent in electrode- less nickel plating of plastics and metals, lab reagent, substitute for sodium nitrite in smoked meats.

 

Sodium Hypophosphite (NaPO2H2) is a versatile chemical compound commonly used in various industrial applications, including electroplating, chemical synthesis, and as a reducing agent. This white crystalline powder is highly soluble in water and plays a crucial role in the production of phosphorus-based chemicals and metal coatings. Due to its excellent reducing properties, Sodium Hypophosphite is particularly valued in applications requiring controlled reduction reactions.

 

Key Features & Benefits:

- Effective Reducing Agent: Sodium Hypophosphite is widely recognized for its powerful reducing properties, making it ideal for electroplating and chemical reactions where reduction is required.

- Electroplating Application: It is a key component in nickel electroplating, where it provides excellent metal coating adhesion and improved surface smoothness.

- Chemical Synthesis: Sodium Hypophosphite is used in the production of phosphorus compounds, such as phosphine and other important chemicals, playing a vital role in many chemical industries.

- Environmental Benefits: It serves as a more environmentally friendly alternative to other reducing agents due to its lower toxicity and reduced environmental impact.

- Versatility: Its ability to perform in acidic and alkaline environments allows it to be used in a wide variety of industrial processes.

 

Applications:

  1. Electroplating: Sodium Hypophosphite is used in the nickel electroplating process, offering better plating uniformity, thicker coatings, and improved corrosion resistance.
  2. Chemical Manufacturing: It is used as a reducing agent in organic synthesis, particularly in the production of phosphorus derivatives and other vital chemicals.
  3. Textile Industry: Sodium Hypophosphite is used in the dyeing and finishing of textiles, enhancing product durability and color retention.
  4. Water Treatment: It is also employed in some water purification and wastewater treatment applications.

 

Packaging & Storage:

Sodium Hypophosphite is available in 25 kg bags or custom packaging for bulk use. It should be stored in a cool, dry place, away from moisture and direct sunlight to maintain product integrity.
