The chemical earth electrode is a new type of grounding device that is easy to install and reliable. Its characteristic is that it can be used in a single tube or in combination with multiple tubes. The ground rod can go deep into the ground, and it is easy to obtain a low ground resistance. The active material filled in the tube can always keep the ground in a constant low resistance state.
The service life of the chemical earth electrode should be understood in two situations, namely the main body life and the ion life.
The life of the main body refers to the life of the rod body and the connector loaded with ionic materials, that is, buried in the ground, it will not be corroded for many years, and the product connection will not fall off by itself;
Ionic body is actually a material that is loaded in the main body and can release ions, generally a powdery substance. This part is equivalent to the consumables in the printer, which is constantly consumed. In the process of its interaction with water molecules, along with soil erosion and continuous dilution of its own components, the function of releasing ions disappears completely. Its life span is far shorter than that of the main body.
So is there a way to solve the problem of the disappearance of this kind of ions and to ensure that they release ions for a long time? Many manufacturers have thought of many ways. The most common method is to use the method of preserving the well cover for the chemical earth electrode during installation, that is, when burying the chemical earth electrode, the chemical earth electrode is not completely buried in the soil, but an end cap is exposed. After a few years, the ion body is consumed, and then the ion body is artificially added to extend the action time of the ion body.
There is another improved solution to change the ion to reduce the aperture of the ion ground hole. At the same time, an external catalyst induction mechanism is used. On the one hand, the release rate of the ion body is reduced, and the externally added induction mechanism ensures the amount of ion release. As a result, the life span of the whole ion body can reach about 8 years. Now various manufacturers are constantly researching and making progress to improve the service life of chemical grounding electrodes.
