Rockaltal RMB

Sulphide-Free Liming Auxiliary for Cleaner and Sustainable Leather Processing

Advanced Liming Auxiliary for Modern Tanneries

Rockaltal RMB is a high-performance liming auxiliary developed for the beamhouse stage of leather processing. Designed as an alternative to conventional Sodium Sulphide, Rockaltal RMB offers efficient pelt opening and grain cleaning while significantly reducing the environmental impact of the liming process.

Unlike traditional sulphide-based chemicals, Rockaltal RMB does not release harmful sulphide ions into tannery effluent. Its unique formulation helps tanneries achieve cleaner production, improved leather quality, and more sustainable wastewater management.

Suitable for all types of leather, Rockaltal RMB can be used in modern and conventional liming processes to produce smooth pelts with fine, tight grains.

Why Choose Rockaltal RMB?

Liming is one of the most critical stages in leather manufacturing, directly influencing grain quality, fiber opening, and downstream processing. Rockaltal RMB has been specially formulated to deliver excellent liming performance while minimizing environmental concerns associated with sulphide-containing products.

Key Benefits:

• Effective alternative to conventional Sodium Sulphide.
• Does not discharge harmful sulphide ions into wastewater.
• Promotes cleaner and more sustainable leather production.
• Produces smooth and well-opened pelts.
• Improves grain cleanliness and tightness.
• Enhances penetration of subsequent leather chemicals.
• Compatible with different leather types.
• Soluble in water and easy to apply.
• Reduces the environmental burden on effluent treatment systems.
• Suitable for modern eco-friendly tanning processes.

How Rockaltal RMB Works?

Rockaltal RMB acts as a liming auxiliary during the beamhouse process, helping to open the fiber structure and improve the cleanliness of the pelt surface.

Its carefully balanced composition promotes:

• Better opening of the collagen fiber network.
• Cleaner leather surfaces.
• Fine and compact grain structure.
• Improved smoothness of the pelt.
• More uniform chemical penetration during later processing stages.

Even when used at higher dosages, Rockaltal RMB is rapidly oxidized by atmospheric oxygen, minimizing the release of harmful substances into the tannery effluent.

Environmental Advantages:

Traditional sulphide-based liming systems can generate sulphide ions and create environmental challenges during wastewater treatment. Rockaltal RMB offers a cleaner alternative.

Sustainability Benefits:

• Sulphide-free effluent discharge.
• Reduced environmental impact.
• Lower load on wastewater treatment plants.
• Supports cleaner production strategies.
• Suitable for environmentally conscious tanneries.
• Contributes to sustainable leather manufacturing.

By reducing harmful sulphide emissions, Rockaltal RMB helps leather manufacturers comply with increasingly strict environmental regulations.

Applications:

Rockaltal RMB is recommended for:

• Beamhouse operations.
• Liming of bovine hides.
• Sheep and goat skins.
• Eco-friendly leather processing.
• Sulphide-reduced liming systems.
• Cleaner leather production processes.
• Sustainable tannery operations.

Technical Specifications

Performance Benefits in Leather Processing

Leather processed with Rockaltal RMB exhibits:

• Cleaner and finer grain.
• Improved pelt smoothness.
• Better surface opening.
• Enhanced grain tightness.
• Improved consistency during subsequent processing stages.

Its ability to support efficient liming while reducing sulphide discharge makes Rockaltal RMB an excellent choice for tanneries focused on quality and sustainability.
