Do not ignore the safety of high temperature mica plate electric heating wire!

The use of any instrument needs to pay attention to its safety issues, because regardless of the use of the results of the security is very important, so in the use of high-temperature mica board and electric heating wire with the safety of the wire can not be ignored, the following we will talk about the high-temperature mica board electric heating wire of several safety issues.

1. Electric heating wire in the corner of the local current is too high, the temperature is too high up to 500-700 degrees above, briefly damage and constitute a danger, in some manufacturers have appeared to mica substrate burned out a black hole, and even the risk of fire. The product is faceted heating, the temperature is uniform, not easy to melt bad.

2. electric heating wire mica electric heating plate due to the choice of gluing process, metal heating wire and high temperature mica plate in the heating expansion coefficient is not the same and briefly layered, together with the high temperature state of the rubber evaporated off after the fall, electric heating wire interwoven briefly short circuit. The product is mechanical articulation, no glue process, high temperature resistance, not easy to fall, safe.

3. Safety such as a few cases, the electric heating wire will first burn a large hole in the mica layer, and will always be super-rated power energized heating, until the electric heating wire fuse, this process can ignite wood floors, carpets and other flammable materials. And the extreme case, such as non-normal voltage use, electric heating film mica heating plate will be personal break and constitute a power drop, or heat parts self-destruction and no longer heat, will not lead to fire and other dangers.

4. Because the electric heating wire is wire heating, so the uniformity of heating is difficult to ensure, the surface temperature of the electric heating wire reached 500 degrees, so the electric heating wire mica electric heating plate after a period of time will be in the high temperature mica board surface baked out of the line of black marks, affecting the beauty. If the surface mica is under the high temperature for a long time, it may affect the service life of the mica substrate.

5. mica heating plate is selected in series circuit design, if a point of damage, then the whole electric heater is scrapped, and the product is selected in parallel circuit design, if the extreme situation, a hot parts even if damaged, and does not affect the other hot parts of the operation, the customer does not feel, after several years of the mall, the electric heating film supporting the factory repair rate of only 0.2%.

6. mica heating plate start current, usually 3-4 times the rated current, in the junction box local also to heat, so the electric heating plate in the local out of the wire box briefly appear to fire the gun appearance, and even in some supporting manufacturers of products appear at the junction box burn a large black hole in the appearance. Product start current is small, usually in the rated current of about 0.8 times, the current is smooth, and the leakage current is usually less than 0.025mA.

7. Due to the specific gluing process of electric heating wire, so that the glue in the high temperature will become powder and volatile unpleasant odor, and the smell of the detection of formaldehyde, customers pay special attention. The product is a glueless process, odorless and environmentally friendly, with SGS environmental statement.
