Abstract
Procedimiento para impedir la formación de sedimentaciones en superficies calentadas, también y preferentemente en aquellas cuyas temperatura es superior a 100º C que están en contacto con agua que contiene sales inorgánicas disueltas, especialmente para impedir la formación de sedimentaciones en cambiadores de calor tubulares por cuyos tubos corre el agua, para lo cual el agua antes de su contacto con las superficies calentadas se añade un agente desincrustante, caracterizado porque con composiciones que forman complejos con cationes se combinan sustancias de efecto aniónico que están capacitadas para formar sales con los cationes ligados a los complejos, y porque por la adición de esta combinación de materias al agua se forman cristralitas de combinación en las zonas cercanas a las paredes de las superficies calentadas.
