Basic Chromium Sulfate (BCS) Product Details
Basic Chromium Sulfate (BCS) Product Description
Basic Chromium Sulfate (BCS) is an essential chemical compound primarily used in leather tanning, dyeing, and various industrial applications. It appears as a green powder or liquid and is highly soluble in water. BCS is valued for its ability to stabilize collagen fibers in leather, enhancing durability, softness, and resistance to wear.
Production Process
The manufacturing of Basic Chromium Sulfate involves several key steps:
- Dissolution: Chromium ore is reacted with sulfuric acid to produce chromium sulfate.
- Reduction: The chromium sulfate undergoes reduction using a reducing agent such as sulfur dioxide or molasses to form basic chromium sulfate.
- Purification: The solution is filtered and concentrated to obtain high-purity BCS.
- Drying & Packaging: The final product is either dried into a powder or kept in liquid form, ready for industrial use.
