With the development of science and technology and the improvement of industrial level, the enamel industry is also constantly upgrading. As early as the late 1980s and early 1990s, a generation of high-efficiency and energy-saving materials, electronic enamel, was successfully developed internationally. Electronic enamel is an enamel steel plate that prints an electric heating film (graphite, silver film or tin film) on the surface of the enamel plate and is used as a heating material after high temperature sintering. The principle is that after the electric heating film coated on the surface of the enamel plate is energized and heated, the heat is directly transferred to the surface of the enamel plate, and is heated by radiation and conduction on the surface of the enamel plate.

At present, electric heating film enamel can be used in convection electric heaters, radiant electric heaters, electric heating physiotherapy tablets, electric hot pots, electric frying pans, electric kettles, electric heating film ovens, industrial baking ovens and medical care equipment. very broad.

Features of electronic enamel:

1. The heat resistance can reach up to 300 ℃, and the heating is rapid;

2. The heat distribution on the heating surface is uniform

3. Good thermal conductivity and high thermal efficiency;

4. Can withstand the test of various harsh use environments;

5. Suitable for high-density circuit printing;

6. Insulation, can be grounded, and can be used as a curved surface.

The surface of the electronic enamel substrate must have good withstand voltage performance, and the enamel surface must not have any pinholes and other districts, otherwise it will cause short circuit and breakdown of the line. In order to ensure that the electronic enamel substrate has good flatness and no defects on the surface, the low temperature long firing process should be used as much as possible, and the temperature distribution in the firing furnace should be uniform, clean and dust-free, and the humidity should be low.
