For a long time, sacrificial anodes, as important anti-corrosion materials in the field of modern production and life, have always been able to play a very outstanding role. However, in actual product applications, different types of products can always play different roles. So how to determine the function of the product? The best way is to use the reference electrode of the sacrificial anode. So, what is the reference electrode of the sacrificial anode?
According to experts in the region who are specialized in the research and development and production of aluminum alloy anode products, many people are not too unfamiliar with the term sacrificial anode. It has a very wide range of applications in the prevention of corrosion of cables, oil pipelines, underground equipment and chemical equipment. And with the deepening of modern production, the actual demand for this product in the industry is also increasing.
In industry, we often use zinc as an anti-corrosion sacrificial anode, which is mainly closely related to the chemical properties and economic value of zinc and zinc anode. In terms of chemical properties, zinc is more active. When a ship is sailing on the sea, because the ship is mainly made of steel, a corresponding chemical reaction will occur in the seawater to form a galvanic cell effect.
At present, there are two main methods of cathodic protection: forced current protection and sacrificial anode protection. The implementation of cathodic protection methods must use anode materials such as magnesium anode and aluminum anode, but the implementation of the project is also inseparable from the application of reference electrodes. The introduction of sacrificial anode reference electrode is mainly as follows:
1. Understanding what is a reference electrode
Because of the unmeasurable potential of the electrode, when applying cathodic protection, a type of potential-suppressed electrode should be used as the relative electrode potential of the potential reference measurement device, that is, the sacrificial anode reference electrode. When selecting a sacrificial anode reference electrode, the following points should be noted: such as considering the reversibility of the electrode reaction, the temperature coefficient of the reference electrode potential, the properties of the reference corrosive medium and the solution in the reference electrode, and whether the electrode is durable and easy to maintain, so that the reference electrode can play the greatest role in cathodic protection.
2. What are the commonly used reference electrodes
At present, the commonly used reference electrodes are mainly the following, such as copper, copper sulfate electrode, silver chloride electrode, calomel electrode, mercurous sulfate electrode, mercuric chloride electrode, and metal electrodes such as zinc, stainless steel, aluminum, and copper. When selecting a reference electrode, it should be selected according to the specific environment of cathodic protection. In general, it is necessary to consider whether the reference electrode is reversible. The irreversible reference electrode composed of metals and alloys and corrosive media is generally strong and durable, and easy to install, but its potential stability and accuracy are not as good as reversible electrodes, so the selection of reference electrodes is as important as the selection of anode materials.
