Electric heating plate is widely used in various fields

Electric heating board is an equipment which USES electric thermal alloy wire as heating material, mica flexible board as insulation material and outsourcing thin metal board (aluminum board, stainless steel board, etc.) for heating. Typical applications are electric thermos bottles. Will cast metal tube shape electric heating element in aluminum plate, aluminum plate, welding or embedded in aluminum plate, aluminum plate above the form various shapes of electric heating coil, electric heating, typical applications for such as electric rice cooker, electric iron, electric coffee pot, electric heating board is widely used in industry, agriculture, civil, defense, science and technology and medical and health care and other fields, fever materials for electric thermal bonding wire, its working principle is very simple, is the basic electric heating effect. When the electrothermal plate is working, the electric current passes through the electrothermal alloy wire, and the electrothermal alloy wire will generate heat, converting electric energy into heat energy and transmitting it to the outer shell. The electrothermal plate is designed with insulation material, so as to ensure that the electric current during the operation of the electrothermal alloy wire will not cause safety risks to the user.

The following points should be paid attention to when using the electric heating plate:

1. Silica gel electrothermal device can work under pressure. That is to say, auxiliary pressing plate can make it close to the heated surface. At this time, the heating plate has good heat conduction, and its power density can reach 3W/cm2 when the working area temperature does not exceed 240℃.

2. In the case of air dry burning condition, the electric power density of the heating plate should be less than 1W/cm2 due to the temperature resistance of the material; Under non-continuous operating conditions, the power density can reach 1.4w /cm2.

3. The working voltage of the heating plate is selected based on the principle of high power - high voltage, low power - low voltage, and special needs can be listed.

4. Its continuous operating temperature should be less than 240℃, and the instantaneous temperature should not exceed 300℃.
