What does sacrificial anode cathodic protection technology mean?

Oct 08, 2024 Leave a message

Sacrificial anode cathodic protection technology refers to the use of a metal (sacrificial anode) with a potential more negative than the metal being protected to electrically connect with the metal being protected. The metal with a more negative potential is continuously corroded and dissolved to protect the metal being protected. This is the sacrificial anode cathodic protection method.

D Type Magnesium Anode
Type D is a common specification of casting anode, the production process is mature. The curved surface can increase the contact area with the medium and enhance the protection effect. And in line with domestic and foreign standards, easy to purchase and replace. The ASTM G97 Electrochemical performance test is a test of the 17D3 sampling rule.
S Type Magnesium Anode
The S-type anode is also one of the most popular shapes, which can be used for the combination of supports and planes.
R Type Magnesium Anode
R/C type anodes are mainly round, and the application environment is different according to the height, small products are used to directly connect the protective body through bolts and nuts, and large ones are still connected to cables and packaging to protect corrosion-prone facilities.
