EDTA for boiler cleaning
The mechanism and characteristics of EDTA cleaning . EDTA cleaning substance is its complex react with metal ions to form a stable complex under certain conditions.. In the cleaning process, it has ionization, hydrolysis, and other complex chemical reactions. It is alkalescence at the beginning , relying on the physical and chemical changes by the boiler , the metal is dissolved and complexed, at end with the fouling disappeared the PH value go up.Clean medium to reach the passivation conditions, so as to achieve the washing and passivation at the same time .
EDTA cleaning agent on the iron and copper deposits and scale type calcium, magnesium scale has a strong cleaning ability, the metal surface after cleaning can generate good corrosion protection film, without further passivation.
