Electric heating element conductive coating
Conductive paint, also known as black film, was produced in the late 1950s and can be used as an electric heating element after being sprayed on the surface of an insulating material. The conductive coating itself has many uses, but it is less used as an electric heating element. Its advantages are planar heating, large heat dissipation area, and good shock resistance, but the disadvantage is that the heating layer is easy to fall off and can only be applied to heating below 200°C. 4. Electric heating film Electric heating film is a new type of electric heating element in recent years. It is manufactured by absorbing the characteristics of two electric heating elements, PTC and conductive paint. Electric heating films are currently mainly used in indoor heating and environmental temperature maintenance, such as building heating, brooding room insulation, etc. The advantages of the electric heating film are no open flame heating, surface heating, low thermal resistance, fast heat conduction, long service life, and easy to cut and separate. In particular, the electric heating film has a power conversion efficiency of up to 90% and low heat loss. The disadvantages of the electric heating film are that the heating speed is slow, the heating temperature cannot reach a high value, and the heat dissipation speed is fast after a power failure.
What is a pipe electric heater?
It is composed of multiple tubular electric heating elements, cylinders, baffles, etc. The tubular electric heating element is a high-temperature resistance wire placed in a metal tube, and the gap is tightly filled with crystal oxidation with good insulation and thermal conductivity. Magnesium powder, using tubular electric heating elements as heating elements, has the characteristics of advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance and wear resistance. A baffle plate is installed in the cylinder body to make the air heat evenly during circulation.
