| Summary: | Influence of acetate ion on stability of alumina-zirconium tanning to alkalization has been investigated in the paper. The investigation results have shown that at the ratio of Al3+:Zr4+:CH3COO = 1:1:1 it is possible to prepare a solution of masking alumina-zirconium tanning (АЦД-М) with high stability and low consumption of aluminum sulfate. The paper reveals that masking of alumina-zirconium tanning by natrium acetate allows to increase stability to alkalization and improve tanning properties. It has been established that for a stable increase of fatty matter viscosity and improvement of leather water-resistant properties it is necessary to use water-insoluble aluminum and zirconium soaps of carboxylic acids. |
