The neon lamp electrode is also called the neon lamp electrode chamber. The electrode chamber is the main part of the neon lamp. Usually, the neon lamp is composed of electrodes, sealing guide wires, heat insulation materials (ceramic rings), insulating materials (mica sheets), glass tubes, and electronic powder layers. composition.
The materials used in the electrodes are copper, pure nickel, cast aluminum, pure iron and nickel-plated iron. Among them, pure iron and nickel-plated materials have long life, high melting point, low cost, low sputtering rate, and the same process and processing methods. Good consistency.
In the lamp making process, degassing is more convenient and easy to operate, but the pure iron electrode is very easy to rust, which will cause the electrode emission performance to decrease; the electroplating process of the nickel-plated iron electrode is difficult to master, and the surface coating is required to be 8-10μ in the electroplating process The thickness of the degree layer is consistent, and the nickel requires extremely high purity, and the plating layer is firm, otherwise serious sputtering will occur. Therefore, the cost of nickel-plated iron electrode is high, and the electroplating process is not easy to control.
