Graphite, you know? There is a problem in high school chemistry. The allotrope of carbon is called graphite. Graphite is very common in life. The pencil lead is graphite. Graphene is a single-layer or multi-layer structure extracted from graphite. Graphite is cheap, but the cost of refining graphene is not cheap.

The most common application of graphene is heating materials, and the wavelength of heat light wave emitted by graphene is about 3-15 microns. The infrared spectrum emitted by human body is basically similar to graphene. The "life light wave" emitted by graphene can be absorbed to produce a thermal effect, which can produce the most effective "resonance" with the water molecules of cells in the biological body, expanding the human microvasculature, strengthening the self-discipline and speeding up the blood circulation. Thus, it can promote the metabolism of the body, increase the regeneration ability of tissues, and improve the immune ability of the body.

Graphene has a really strong heat conduction ability. Generally, the heating element on the heater is copper or aluminum. The thermal conductivity of pure aluminum is 217.7W/mk, and that of pure copper is 376.8W/mk. The thermal conductivity of pure single-layer graphene is 5300W/mK, which is the carbon material with the highest thermal conductivity at present.

Of course, we can't use pure graphene as the heater, because the cost is too high. When it is used as the carrier, the thermal conductivity can reach 600W/mK, which is much higher than that of pure aluminum and copper. Besides, we won't use pure copper and aluminum as the heater. Therefore, there are still great advantages in using graphene for heat dissipation of heaters. Compared with other common radiators, graphene radiators have great advantages.

Graphite heat dissipation coating developed by microcrystalline material science and technology. It has excellent high temperature resistance, hydrophobicity and moisture-proof performance, electrical insulation performance and heat dissipation performance. When the coating is applied to the surface of an object, it can significantly enhance the infrared thermal radiation intensity of the surface, make the heat radiate to the surrounding in the form of infrared light waves, and have a good positive effect on the heat dissipation/thermal radiation efficiency of the object. It is widely used in barbecue ovens, heaters, garden grills, high-temperature ovens, automobile and motorcycle silencers, H-class insulating coatings and heat dissipation in scenes with high temperature resistance of 500 ℃ or above.

Product features

1. It has good temperature resistance and can be used continuously at 400~600 ℃ without smoke and odor.

2. The high thermal radiation coefficient can significantly improve the radiation and heat dissipation capacity of the high-temperature heater.

3. Excellent adhesion and insulation, high hardness, suitable for various metal substrates.

4. It has good wear resistance, scratch resistance, corrosion resistance and heat resistance.
