Based on comparison and learning of the present standard methods

and combined with the desulfurated flue gas quality's demand on anti-corrosive coating performance

inspection and assessment methods for several key properties such as adhesive force

toughness

wear resistance

impermeability

acid-fastness and temperature tolerance etc.of the anti-corrosive coating on stack in thermal power plant were determined.Furthermore

they were used to evaluate 12 kinds of the anti-corrosive coatings.Results show that

the most suitable coating for stacks under special application conditions can be selected via the evaluation methods mentioned above.Withal

the specific steps and suggestions for selecting the stack coating are given.
