Abstract
The invention belongs to the technical field of heating lamps, particularly relates to a preparation method of a high-thermal-conductivity graphite flake heating lamp. The high-thermal-conductivity graphite flake heating lamp comprises a quartz outer tube material, a high-thermal-conductivity graphite flake material, a molybdenum wire and a molybdenum rod, the preparation method comprises the following steps: S1, carrying out high-temperature dehydroxylation treatment on a quartz tube outer tube material (OH is less than or equal to 5ppm); S2, carrying out ionized water cleaning and hot drying on the quartz tube material; S3, applying a high-thermal-conductivity graphite flake; and S4, fixing joints at two ends. According to the invention, the high-thermal-conductivity ultrathin graphite flake 0.1-5 mm is used as a heating body material, so that the heating area is increased, the electro-thermal conversion efficiency is improved, and the service life of the heating lamp is prolonged. Meanwhile, the movable molybdenum lining wire for preventing the loss rate from being reduced is innovatively designed to be connected with the molybdenum rod, so that a user can move and use according to different places, and the application effect is greatly improved.
Description
technical field [0001] The invention relates to the technical field of heating lamps, in particular to a preparation method of a high thermal conductivity graphite sheet heating lamp. Background technique [0002] Heating lamp is a kind of heater with high temperature and long life. Modern industry needs higher and higher working temperature, especially in chemical fiber, engineering plastics, plastic machinery, electronics, medicine, food and various pipeline heating. The heating lamp consists of The spiral resistance wire is formed by extending through specially designed high temperature resistant ceramic tiles, which can be bent. [0003] At present, the heating lamps produced by the domestic lighting appliance industry generally use tungsten wire, spiral carbon fiber, fully woven carbon fiber or multi-filament carbon fiber, etc., which have many production processes, high cost, and relatively low heat conversion efficiency. It cannot meet the technical needs of high the...
