How does the mica board work after heating?

With the continuous development of mica board technology, mica board manufacturers have gradually penetrated into people's daily life.

1. Mica plate heating wire Mica heating plate is simply layered due to the choice of bonding process, the expansion coefficients of the metal wire and the mica plate are different after heating, plus the simple drop of the glue after evaporating at high temperature, E electric heating lines are staggered Simple short circuit.

2. Due to the special bonding process of the heating wire, the mica board will turn into powder at high temperature and emit an unpleasant smell, and the smell is rich in formaldehyde.

3. The local current of the heating wire of the mica board at the corner is too high, the temperature is too high, it is easy to be damaged and there is a danger. Some manufacturers have shown that the mica substrate has burned out the black hole, and even caused the danger of fire.

4. Mica plate Mica under high temperature for a long time will affect the service life of the mica substrate.

5. Mica plate The mica heating plate has a large starting current, usually 3-4 times the rated current, and also needs to be heated in the junction box.

6. Mica plate Mica heating plate is a series circuit design, if one point is damaged, then the whole electric heater will be scrapped

7. Safety.
