The Importance of Heating Membrane
Environmental protection and energy conservation are major issues of concern today. It is very important to promote clean energy and energy-saving technologies applied in various fields. Electric heating has entered the field of urban heating as a clean energy source. The use of radiant electric heating systems for heating is in line with the current social development needs. As a new technology and smart material, the electric heating membrane, which can generate heat after being energized, has received widespread attention. It is a flat heating element composed of an electric insulating material and a heating resistor material in the package.
Accelerate Research and Practice of Graphene in Heating Membrane
Graphene has high electrical conductivity and high thermal conductivity. It has been made into a membrane material, and electricity can be generated when the electrodes at both ends are energized, which forms electrothermal conversion. At the same time, the graphene heating membrane can instantly heat up and maintain a higher heating temperature. Graphene heating membrane consumes very low power, and only needs a lower voltage to achieve high heat generation. The special phonon vibration mode in the process of thermal energy radiation can emit far-infrared rays with a wavelength of 5-14 microns and radiate them uniformly in a planar manner. The total conversion rate of effective electric heating energy is over 99 %.
