Abstract

A.COMPOSITION A BASE D'UN SILICATE, D'UN DURCISSEUR ET D'UN SUCRE ET SON APPLICATION AU DURCISSEMENT A FROID DES SABLES. B.CETTE COMPOSITION EST CARACTERISEE EN CE QUE LE SILICATE EST UN SILICATE DE METAL ALCALIN ME DONT LE RAPPORT PONDERAL SIOMEO EST COMPRIS RESPECTIVEMENT, LORSQUE ME REPRESENTE LE SODIUM, LE POTASSIUM ET LE LITHIUM, ENTRE 1,9 ET 2,4; 1,2 ET 1,6; 3,9 ET 5 ET EN CE QUE LE SUCRE EST UN SACCHAROSE POSSEDANT UNE PURETE SUPERIEURE A 99,9. C.UTILISATION DES SABLES REGENERES POUR LA FABRICATION DE MOULES ET NOYAUX.A. COMPOSITION BASED ON A SILICATE, A HARDENER AND A SUGAR AND ITS APPLICATION TO COLD CURING OF SANDS. B. THIS COMPOSITION IS CHARACTERIZED IN THAT THE SILICATE IS AN ALKALINE METAL SILICATE OF WHICH THE SIOMEO WEIGHT RATIO IS INCLUDED RESPECTIVELY, WHEN ME REPRESENTS SODIUM, POTASSIUM AND LITHIUM, BETWEEN 1.9 AND 2.4; 1.2 AND 1.6; 3.9 AND 5 AND IN THAT SUGAR IS A SACCHAROSE WITH A PURITY GREATER THAN 99.9. C. USE OF REGENERATED SANDS FOR THE MANUFACTURE OF MOLDS AND CORES.
