Свойства вольфрамовой фольги

Tungsten foil is a thin film made of tungsten metal with a thickness ranging from 0.1 micron to 5 microns. It has a glossy and smooth surface, high hardness and anti-friction properties, and has good corrosion resistance. and conductive properties.

1. Characteristics of tungsten foil

1. Tungsten foil has excellent thermal stability, thermal expansion resistance and thermal conductivity, and has good performance under high temperature conditions;

2. Tungsten foil has high anti-friction performance, good wear resistance and longer life;

3. Tungsten foil has good thermal conductivity and heat can be conducted quickly;

4. Tungsten foil has heat resistance and corrosion resistance, and its corrosion resistance is particularly strong;

5. Tungsten foil has electrical insulation and excellent electrical properties.

2. Uses of tungsten foil

1. Tungsten foil is widely used in electronic equipment, such as television tubes, computer monitors, mobile phone panels, etc.;

2. Tungsten foil is also used in the manufacture of electronic components, such as capacitors, resistors, relays, etc.;

3. Tungsten foil has beautiful appearance and can be used to make decorations, jewelry, etc.;

4. Tungsten foil can also be used in aerospace, military and other fields to manufacture high-temperature fuel thrusters;

5. Tungsten foil can also be used in the manufacture of medical devices and implanted organs.

3. Manufacturing process of tungsten foil

1. The manufacturing processes of tungsten foil mainly include smelting method, electrolysis method, liquid phase method, etc.;

2. The smelting method is a traditional manufacturing method that melts tungsten powder into a metal mold to form tungsten foil;

3. The electrolysis method is a high-precision manufacturing method that dissolves tungsten powder in the electrolyte and then undergoes an electrolysis process to form tungsten foil;

4. The liquid phase method is a method for quickly preparing tungsten foil. The tungsten oxide powder is dissolved in a solvent, and then goes through steps such as solidification, washing, and drying to form a tungsten foil.

4. Precautions for tungsten foil

1. Tungsten foil is a thin film of tungsten metal, which has good electrical insulation properties, but is also easily affected by humid environments;

2. Tungsten foil has excellent wear resistance, but it is also susceptible to erosion by metal debris, sand and other external substances;

3. Tungsten foil has excellent corrosion resistance, but it is also susceptible to corrosion by corrosive substances such as strong acids and alkalis;

4. Tungsten foil has heat resistance, but is also easily affected by high temperature environments;

5. Tungsten foil has excellent electrical properties, but it is also easily affected by electromagnetic fields such as high voltage and high frequency.

5. Construction method of tungsten foil

1. The construction methods of tungsten foil mainly include laminating method, welding method, glue coating method, etc.;

2. The lamination method is to laminate the tungsten foil to the surface and fix it through hot pressing, cold pressing, etc.;

3. The welding method is to weld the tungsten foil to the surface and use the thermal stability of the tungsten foil itself to achieve fixation;

4. The glue coating method is to coat the tungsten foil with silicone or other adhesives, and then apply the tungsten foil to the surface to achieve fixation.

Tungsten foil is a thin film of tungsten metal with excellent thermal stability, thermal expansion resistance and friction resistance. It can be widely used in the manufacturing of electronic equipment, aerospace and other fields, and can also be used in decorations, jewelry, etc. There are also some precautions that need to be paid attention to during construction to ensure construction quality.
