Graphene is a new carbonaceous material in which carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. It has excellent crystallinity, mechanical properties and electrical quality. Graphene has very good thermal conductivity. After the graphene electric heating film is energized, it radiates heat in the form of far infrared. Generally, the far-infrared wavelength of the graphene electric heating film is 5-12um, which can be absorbed by the human body. The human body provides heat to the room, and its electric heat conversion rate is as high as 87%, which is much higher than other electrical appliances.
This article is a graphene electrothermal film performance testing instrument plan, including experimental film coating machine, coating Thickness Gauge, viscometer, coating dispersion test equipment, grinding dispersion equipment, pinhole detection, and combustible gas detection.
