Neon lights in the production process, whether it is a bright tube, a powder tube or a color tube, the production process is basically the same, they all need to go through glass tube forming, sealing electrodes, bombardment degassing, filling inert gas, sealing venting holes, etc. Process.
Glass tube forming—the process in which the production staff passes the special fire head along the outline of the pattern or text, and burns, bakes, and bends the straight glass tube into a pattern or text. The level of the production staff can be seen by the naked eye, and the level is low. The lamp made by the staff is prone to unevenness, too thick or too thin, the inner wrinkles, and the unevenness of the plane.
Sealing electrode—The process of connecting the lamp tube to the electrode and the vent hole through the fire head. The interface should not be too thin or too thick. The interface must be completely burnt, otherwise it will be prone to slow air leakage.
Bombardment is the key to making neon lights. The high-voltage electric bombardment electrode is used to heat the electrode to incinerate the water vapor, dust, oil and other substances invisible to the naked eye of the lamp tube, to discharge these harmful substances, and to evacuate the glass tube into a vacuum process. The temperature of the bombardment degassing is not reached, and the above harmful substances will not be completely removed, which directly affects the quality of the lamp. Excessive temperature of bombardment degassing will cause excessive oxidation of the electrode, causing an oxide layer on its surface, causing the quality of the lamp to decrease. The glass tube that has been completely detonated and degassed is filled with a suitable inert gas. After sophistication, the neon production process is completed.
