Cleaned tungsten wire is a specially treated tungsten wire with a smooth, bright and clean surface, showing a silver-gray metallic luster. Compared with black tungsten wire, the surface of cleaned tungsten wire is smoother, has higher purity and fewer impurities. This processing method makes cleaned tungsten wire widely used in the electronics industry, especially when manufacturing products such as electron tubes and transistors, which can improve the performance and stability of the product.
During the manufacturing process, cleaned tungsten wire is a tungsten wire after the graphite layer on the surface of black tungsten wire is cleaned by electrolytic alkali cleaning or chemical alkali cleaning. This process can remove impurities and graphite layers on the surface of the tungsten wire and improve the purity and surface quality of the tungsten wire. During the electrolytic alkali cleaning or chemical alkali cleaning process, it is necessary to control the corresponding chemical reagents, concentration, temperature, time and other parameters to ensure the treatment effect and the quality of the tungsten wire.
In addition to the difference in surface quality, cleaned tungsten wire and black tungsten wire also have different application fields. Black tungsten filament is mainly used to make filaments and heating elements in light bulbs, electron tubes and other products, while white tungsten filament is mainly used to make electrodes and leads in electron tubes, transistors and other products. Because cleaned tungsten wire has the characteristics of high purity, high density and high strength, it is also widely used in high-speed cutting of alloy steel, super-hard molds and other fields.
In short, cleaned tungsten wire is a specially treated tungsten wire with the characteristics of high purity, high density, high strength and good electrical conductivity. It is widely used in the electronics industry and other fields. During the manufacturing process, it is necessary to go through processes such as electrolytic alkali washing or chemical alkali washing, and control the corresponding parameters and processing conditions to ensure that the cleaned tungsten wire produced has high quality and high stability.
