Abstract

Inventia se refera la obtinerea unor complecsi de crom aluminiu cu continut de Cr indice 2O indice 3 si Al indice 2O indice 3 în raport de 70 : 30 si bazicitate 33% sub forma de solutie sau pulbere, destinati a fi folositi la tabacirea si retabacirea pieilor, având ca efect o diminuare a consumului de crom sau a altor materiale folosite la prelucrarea pieilor. Se reduce, de asemenea, gradul de poluare cu crom a solutiilor si namolurilor rezultate din tabacarii.The invention relates to the production of aluminum chromium complexes having a Cr index of 2O index 3 and an index of 2O index 3 in a ratio of 70: 30 and a basicity of 33% in the form of a solution or powder, to be used for tanning and re-wearing of hides , resulting in a decrease in consumption of chromium or other materials used in leather processing. It also reduces the degree of chromium pollution of solutions and sludges from tanning.
