Abstract

EN LAS COMPOSICIONES DESINCRUSTANTES DE CAL CON UN PH DE 1 A 5, QUE CONTIENEN DE UN 1 A UN 15 % EN PESO DE UN ACIDO DICARBOXILICO Y DE UN 1 A UN 30 % EN PESO DE UN TENSIOACTIVO ANIONICO QUE NO SEA UN ACIDO GRASO, LA PRESENCIA DE UN 0,1 A UN 10 % EN PESO DE UN ACIDO GRASO EVITA AL INESTABILIDAD A BAJA TEMPERATURA DEL PRODUCTO QUE LLEVA A LA PRECIPITACION DEL ACIDO DICARBOXILICO.IN COMPOSITIONS OF DISINCRUSTING CAL WITH A PH OF 1 TO 5, CONTAINING FROM 1 TO 15% BY WEIGHT OF A DICARBOXYLIC ACID AND FROM 1 TO 30% BY WEIGHT OF AN ANIONIC TENSIOACTIVE THAT IS NOT A FATTY ACID, THE PRESENCE OF 0.1 TO 10% IN WEIGHT OF A FAT ACID AVOID THE UNSTABILITY AT LOW TEMPERATURE OF THE PRODUCT THAT LEADS TO PRECIPITATION OF THE DICARBOXYLIC ACID.
