Introduction:
Appearance: colorless or slightly yellow liquid
Main use:
Replace traditional ammonium salts and borates for deliming of various original thickness and split gray leathers, greatly reducing ammonia nitrogen emissions during the deliming process.
Performance characteristics:
1. It does not contain ammonium salts and borates. It is a clean, safe and efficient deliming agent.
2. It has excellent buffering properties to avoid deliming quality problems caused by a sudden drop in the pH of the bath liquid.
3. The deliming speed is balanced, the grain surface is smooth and fine, effectively reducing growth lines and improving the leather yield.
4. It can prevent skin dirt from being re-adsorbed on the leather surface, and has a certain effect of cleaning the grain surface.
Usage and dosage:
For single use:
Original cowhide: 2.5-3.5%
Cowhide with slices up to 3.5mm: 1.2-2.0%
Cowhide with slices up to 2.0mm: 1.0-1.5%
Used with other deliming materials: 0.5-1.5%
