Abstract

LE MATERIAU COMPREND UN POLYMERE SOLUBLE DANS L'EAU ET UN ACCELERATEUR DE DISSOLUTION QUI DEVIENT EFFERVESCENT PAR CONTACT AVEC L'EAU POUR ACCELERER LA DESAGREGATION ET LA DISSOLUTION DU MODELE. L'ACCELERATEUR DE DISSOLUTION EST CONSTITUE PAR UN ACIDE ET UN CARBONATE OU UN BICARBONATE, LES DEUX ETANT SOUS FORME SOLIDE; ET L'ACIDE EST AVANTAGEUSEMENT DE L'ACIDE TARTRIQUE.THE MATERIAL INCLUDES A WATER SOLUBLE POLYMER AND A DISSOLUTION ACCELERATOR WHICH BECOMES EFFERVESCENT ON CONTACT WITH WATER TO ACCELERATE DISAGREGATION AND DISSOLUTION OF THE MODEL. THE DISSOLUTION ACCELERATOR CONSISTS OF AN ACID AND A CARBONATE OR A BICARBONATE, BOTH BEING IN SOLID FORM; AND THE ACID IS ADVANTAGEOUSLY TARTARIC ACID.
