Abstract

Il s'agit d'aluminosilicates alcalins en fines particules insolubles dans l'eau répondant à la formule générale : (Cat2 /n O)x , Al2 O 3 , (SiO2 )y dans laquelle Cat représente un ion de métal alcalin, de préférence l'ion sodium, x est un nombre de 0,7 à 1,5, y est un nombre de 0,8 à 6, de préférence de 1,3 à 4, à une dimension de particules de 0,1 à 25 microns, de préférence de 1 à 12 microns, et présentant un pouvoir de fixation du calcium de 20 à 200 mg de CaO par g de substance active anhydre, dans la préparation des cuirs. L'utilisation de ces aluminosilicates au dégraissage, au prétannage et à la neutralisation des cuirs permet d'économiser des reactifs coûteux et d'amoindrir la pollution des eaux résiduaires.They are alkaline aluminosilicates in fine particles insoluble in water corresponding to the general formula: (Cat2 / n O) x, Al2 O 3, (SiO2) y in which Cat represents an alkali metal ion, preferably sodium ion, x is a number from 0.7 to 1.5, y is a number from 0.8 to 6, preferably from 1.3 to 4, with a particle size of 0.1 to 25 microns , preferably from 1 to 12 microns, and exhibiting a calcium binding power of 20 to 200 mg of CaO per g of anhydrous active substance, in the preparation of leathers. The use of these aluminosilicates for degreasing, pre-tanning and neutralization of leathers makes it possible to save costly reagents and to reduce pollution of waste water.
