Taking tanning to the next level with an improved pickle product

摘要

With Blancorol HP the traditional tanning process can be taken to the next level. This is achieved the first time by combining all the existing concepts to improve the pickle in only one product. All pickle parameters (pH, masking agent and time) have been taken into account and the associated challenges for the tanning process have been minimised. This improves both the quality of the wet blue and the resulting leather through reduced hydrolysis. Furthermore, the overall tanning is also improved from an environmental point of view by reducing the salt load and chrome content in the floats. A further advantage is the significant reduction of the required process time while maintaining the robustness and production reliability of the standard tanning system. This is shown by the comparison in the tanning of thick, unsplit hides, which succeeds with minimal adjustments to the pickle process. The Blancorol HP product thus meets all the defined targets in order to provide chrome tanning with a further product solution for improving the system.
