Gold plating (0.3μm thickness) and specially treated tungsten have also been developed and put into practical use!
We handle "filaments and ionization wires for sterilization lamps." In fluorescent lamps, ultraviolet light collides with fluorescent materials inside the tube to become visible light, whereas in sterilization lamps, ultraviolet light passes through the quartz glass tube without being converted, allowing for sterilization and disinfection of the external environment. The filaments used in sterilization lamps are coated with electron-emitting materials to facilitate the generation of thermionic electrons. Additionally, "ionization wires" are typically around 0.1mm in diameter due to discharge and strength considerations, but the wire diameter can be selected as needed. 【Features】 <Filaments for sterilization lamps> ■ Coated with electron-emitting materials to facilitate the generation of thermionic electrons ■ Coiled coils are used to increase the surface area, resulting in filaments that are wound in double or triple layers *For more details, please refer to the PDF document or feel free to contact us.
