Cathodic protection potential of storage tank
The cathodic protection commonly used for storage tanks is impressed current cathodic protection
After the construction is completed, the potential of the storage tank can be displayed on the display cabinet of the potentiostat
The principle is the same as that of the pipeline
One cable is connected with the storage tank, and the other cable is connected and buried on the reference electrode around the storage tank
The tank potential can be measured

The measurement of potential is actually to measure the potential difference between the protected metal and the reference electrode
The potential of the reference electrode we use is certain
Any change in the measured current is considered to be the change of structural potential
In fact, this is not the case
It is also possible that the potential of the reference electrode has changed
There are several possible effects on the reference electrode: the effect of temperature: the general effect may be the increase of temperature and the change of solution concentration, resulting in the change of reference electrode potential
It also affects the linearity of the reference electrode potential
For common copper sulfate or copper sulfate reference electrode, the temperature influence range is about 0
9mv / & deg; C。 The potential measured by the conventional pipeline should be -0
85v when the temperature is about 26 degrees
When the temperature drops to about 5 degrees, the potential measured by us is about -0
825v
Therefore, when we measure the * storage tank, we should consider the influence of * heating
For our applicable portable reference electrode, we should also consider the potential change caused by solar irradiation
Generally, the potential change is about 10 MV
In order not to make the reference electrode change too much, we can wrap it with black tape
The change of the tank bottom plate will also lead to the change of the measured potential, such as the deformation and protrusion of the bottom plate caused by * heating
When the bottom plate is tilted, some of the bottom plates will not contact the tank foundation, can not get more protective current and polarize
In order to avoid this phenomenon, the measured data is inaccurate
During the measurement, the liquid level in the tank should be kept at about 2 / 3 for a certain time
