Is the metal electric heater reliable? This is a question that most people who use this product often ask. Because the thin electric heater is a new non-standard product, not too many people understand it. Some simple clarifications to discuss the use of metal electric heaters:

First of all, the electric heating film electric heating plate is designed according to the electrician and electrical specifications when designing, no matter it is the heating wire or the wiring part, there is a certain creepage interval;
Secondly, the insulation materials used by the electric heating film, whether it is PET, polyimide, silicone rubber, or mica, have a good insulation effect. The tested electrical strength: 1500V/1min5mA, no flashover phenomenon , Insulation resistance: ≥5 MΩ. Therefore, there is no leakage phenomenon;
Third, different environments and different temperatures use different insulation materials. When the customer places an order, the relevant personnel of our company will make a certain evaluation according to the customer's request temperature, and then recommend a suitable electric heating film, without worrying about the temperature being too high and burning the insulation layer;
Fourth, the insulation materials used by the electric heating plate during consumption are made through high temperature and high pressure, which ensures that it will not show the heating wire exposed in a certain operating temperature range;
Fifth, when designing the electric heater, our company will design the power according to the temperature. The internal heating wire of the waste heater will adjust its own power according to the temperature. At the same time, a temperature control switch can be installed, which is equivalent to double maintenance;
After the above analysis, the heating plate is safe in use, and its surface heating and temperature average characteristics will be increasingly ignorant by many designers and users.
Silicone electric heating plate adopts heating plate heating core technology, which can basically deal with the following problems:
1. The heating plate heats evenly, which cannot be achieved by ordinary heating wires. The ordinary heating wires are arranged artificially on the silicon rubber electric heating belt. There is no difference in the width between the wires. The heating plate is designed by computer. The spacing can be accurate to two decimal places;
2. The heating plate has stable power and fast heating. The silicon rubber heating plate using the heating plate has the characteristics of fast heating and high heat conversion. The internal alloy resistance plate is generally iron-chromium-aluminum alloy. This kind of material is naturally the first choice for the heating core;
3. The silicon rubber heating plate adopts metal heating plate to greatly increase the unit power density, up to 2W/cm2;
The heating plate has the above advantages, but at the same time there will be some shortcomings in practical use, as follows:
1. In practical consumption, some parts of the silicone rubber heating plate are relatively long, but there are more or less restrictions on the length of the heating plate;
2. The width of the heating plate determines the width of the silicone rubber heating plate, and the conventional heating plate is also tens of centimeters wide, due to the limitation of the etching machine;
3. From the beginning of the design, the heating film has higher requirements than the artificial threading method, and each process is more rigorous;
4. Silicone rubber heating plate with heating plate, the price per square meter is higher than the cost of artificial cloth silk.
