Abstract

Le procédé de nettoyage est utilisable notamment pour lessiver les faces externes de tubes de générateur de vapeur. On élimine les oxydes métalliques en surface par une complexation (pouvant être précédée d'une réduction), puis on effectue une mise en solution des composés siliceux par une réaction en milieu aqueux d'insertion avec des composés électrophiles ou une réaction en milieu aqueux de condensation avec des alcools ou amines, destinée à affaiblir les liaisons, dans un milieu assurant la complexation de Si (OH)4 .
