Combined with the power gas corrosive medium and corrosive environmental characteristics of thermal power plants using “smoke tower one" emissions technology, cooling towers The lining anti-corrosion technologies in concrete materials were compared.The requirements of anti-corrosion lining or coating on the new reinforced concrete substrate surface equipment and its impact on the existing reinforced concrete equipment were introduced.It was pointed out that the cooling tower corrosion scheme was the thick film flake paint was used ,the designed layer thickness was1.2 mm.
