CHEMICALS FOR ALL

Beamhouse Operations/Process:

• Preservation/Curing: Preservation methods like salting or brine curing are used to prevent decay. 
• Soaking: Hides are soaked in water to remove salt and restore moisture. 
• Liming: Alkali solutions (like lime) are used to loosen hair and prepare the hide. 
• Unhairing: Excess hair and tissues are removed through scraping or other methods. 
• Deliming: Lime is removed from the hide. 
• Bating: Enzymes are used to soften the hide and prepare it for tanning. 
• Pickling: Hides are soaked in acidic solutions (often sulfuric acid and formic acid) to prepare them for tanning. 

Tanning:

• Tanning: This is the core process where tanning agents (like chromium salts or vegetable tannins) are used to stabilize the collagen fibers.
• Chromium Tanning: Chromium sulfate is commonly used to produce a flexible and durable leather.
• Vegetable Tanning: Uses plant-based tannins (like from oak bark) for a different type of leather.

Finishing:

• Drying: Water is evaporated to create a dry leather product. 
• Dyeing: Dyes are applied to give the leather color. 
• Fat Liquoring: Oils and greases are added to improve softness and water resistance. 
• Finishing: Coatings and treatments are applied to enhance appearance and durability. 

Key Chemicals Used:

• Sodium sulfide: Used for dehairing.
• Calcium hydroxide (lime): Used in liming.
• Sulfuric acid and formic acid: Used in pickling.
• Ammonium salts: Used in deliming.
• Enzymes: Used in bating.
• Tanning agents: Chromium salts (like chromium sulfate), vegetable tannins, and aldehydes.
• Dyes: Used for color.
• Oils and greases: Used for fat liquoring.
• Coatings and finishing agents: Used for enhancing appearance and properties.
