Abstract
L'INVENTION A POUR OBJET LA STABILISATION DU PERCARBONATE DE SODIUM ET NOTAMMENT SA STABILISATION AU STOCKAGE. ON LE TRAITE PAR UNE SOLUTION AQUEUSE D'UN METAL ALCALINO-TERREUX POUR FORMER UNE MINCE COUCHE DE CARBONATE DE METAL ALCALINO-TERREUX A LA SURFACE. LE PERCARBONATE DE SODIUM RESULTANT EST AMELIORE SUR LE PLAN DE SON CARACTERE NON HYGROSCOPIQUE, TOUT EN CONSERVANT SA SOLUBILITE DANS L'EAU ET SA TENEUR INITIALE EN OXYGENE EFFICACE. UTILISATION DE CE PRODUIT POUR LE BLANCHIMENT, EVENTUELLEMENT EN MELANGE AVEC UN DETERGENT.THE OBJECT OF THE INVENTION IS THE STABILIZATION OF SODIUM PERCARBONATE AND IN PARTICULAR ITS STABILIZATION IN STORAGE. IT IS TREATED WITH AN AQUEOUS SOLUTION OF AN ALKALINO-EARTH METAL TO FORM A THIN LAYER OF ALKALINO-EARTH METAL CARBONATE ON THE SURFACE. THE RESULTING SODIUM PERCARBONATE IS IMPROVED IN ITS NON-HYGROSCOPIC CHARACTER, WHILE RETAINING ITS SOLUBILITY IN WATER AND ITS INITIAL EFFICIENT OXYGEN CONTENT. USE OF THIS PRODUCT FOR BLEACHING, POSSIBLE IN MIXING WITH A DETERGENT.
