PROCEDURE FOR THE TREATMENT OF PROTECTION AGAINST CORROSION OF METAL SYSTEMS OF WATER DRIVING UNDER PRE-CONDITIONING OF THE PROTECTIVE AGENT AGAINST CORROSION.

摘要

Procedure for the corrosion protection treatment of metallic water conduction systems by means of the dosed addition of a combination of silicates and phosphates to the water stream of the metallic water conduction system characterized in that it comprises the following steps: - mixing of a first solution, containing phosphates, with a second solution, containing silicates, to form a third solution, - the concentration of phosphates being found in the third solution, calculated as PO4, between 0.5 and 10% in weight and concentration of silicates, calculated as SiO2, between 0.5 and 7% by weight and taking place in the third solution a process of maturation recognizable by the increase in cloudiness and / or viscosity e - interruption of the process of maturation by injection of the third solution in the main water stream of the metallic water conduction system, after the cloudiness has increased relative to cloudiness Immediately after the union of the two solutions by a factor in the range of 1.5 to 50 or that the viscosity of the solution has increased relative to the viscosity immediately after the union of the two solutions in a factor located in the range between 1.5 and 10.
