Graphite electrodes are more suitable for the characteristics of the material, even if there are too many embedded defects or particles, they will not damage the coating (GPA) (effective coating thickness, total content, and coating film thickness). In our daily work, we ensure good maintenance and production by embedding defects, special coatings, and fine graphite structures; at the same time, the production and maintenance of graphite electrodes are also the focus of the entire manufacturing process, so around this process, we carry out Reasonable maintenance is the most important; currently commonly used maintenance can be carried out according to the following two points:

1. Long-term maintenance of graphite electrodes

2. Carry out short-term maintenance for graphite electrodes.

1. Long-term maintenance of graphite electrodes is generally extended from general electrode maintenance. It is also the purpose of using zinc because zinc can be used for the development of graphite electrodes and graphite oxide. When using, you need to pay attention, in the case of using zinc, pay attention to the anti-deformation of graphite electrodes; according to the difference between zinc and zinc, our electrode maintenance can be divided into zinc salt maintenance, zinc aluminum alloy nickel silicon alloy maintenance, zinc copper maintenance, zinc-molybdenum alloy maintenance, and iron maintenance; after completing zinc salt maintenance, we need to use magnesium powder or nickel-aluminum alloy powder for graphite electrodes. The condition of these powders is already very small, very small, so they can be used together; in addition to the anti-deformation of the electrode, we also need to consider the maintenance of the thin layer of the graphite electrode, that is, after we complete the zinc salt maintenance, we need to remove the thin layer of the graphite electrode. The removal of the layer, which means that there is a wear-resistant layer, is the real need for daily maintenance. The maintenance of the copper-aluminum alloy in the early stage is the most important. If the copper-aluminum alloy is not properly maintained, the upper layer and the maintenance layer are also easily deformed. , we need to complete the maintenance of the copper and aluminum alloys before we can carry out the maintenance of the graphite electrode; before we carry out the maintenance of the graphite electrode, we must first consider the maintenance of the thin layer of the graphite electrode. If the maintenance of the thin layer is not in place, The later maintenance may not be of great significance. According to the situation of thin-layer maintenance, we need to dismantle all the metal structures, remove the thin-layer covering layer, and supplement the metal protective layer. Before we carry out thin-layer maintenance, we must first Carry out follow-up maintenance of a stable metal protective layer and add it to an acceptable thickness. We need to study. During maintenance and disassembly, the thickness of the metal protective layer should be greater than the thickness of the thin layer maintenance; magnesium powder, or nickel-aluminum alloy For powder, you need to look at the maintenance situation and find an acceptable range for yourself; as magnesium powder or nickel aluminum alloy, the mixture of zinc and arsenic should not be present during maintenance. As for iron powder, the maintenance is of little significance, mainly due to the problem of anti-deformation of graphite electrodes. Graphite electrodes are generally in a two-stage solid solution state. If zinc powder or lead powder with copper, nickel, and lead is mixed, it needs to be maintained with smaller copper and palladium. Nickel ions are The ion with the largest content in all graphite electrodes, if the source is not good, the electrode will be short-circuited, just like the short-circuit phenomenon in galvanized or iron maintenance. Of course, in the current industrial production, there is also a copper sulfate maintenance method. It is to use the method of copper stannate for maintenance, which does not contain other metals such as copper and lead, but it is still required.
