When using sacrificial anodes, it is necessary not only to ensure that the electrical insulation and electrical continuity of the corrosive medium must be conductive, but also to ensure that certain conditions of use are met, so that it can be more conducive to the expected use effect. Since the sacrificial anode plays a protective role in the process of use, if the quality of the sacrificial anode is not up to standard, it will directly lead to the equipment not being able to operate normally.
