By reviewing the inhibition mechanisms of scale inhibitors which are commonly used in daily life, their charecteristics and limitation are discussed. It is proved that only chelation and part of dispersion capacities of the scale inhibitors can be evaluated by the static method, aeration method, utmost carbonate hardness method, pH shift method and conductance method. The rest part of the dispersion capacity and the crystal distortion capacity cannot be considered by the above methods. Therefore, these methods are only suitable for middle-or low hardness cooling systems. At the end, the evaluation methods concerning the dispersion capacity and crystal distortion capacity of scale inhibition have been introduced.
