What is an electrothermal film mica heating sheet?
Among the types of household heaters, heaters using electrothermal film mica heating sheets have been popular in the domestic and overseas markets for many years, and have been loved by consumers. For this type of heater, its heart is the electrothermal film mica heating sheet, which can also be called the most core technology. exactly
What is an electrothermal film mica heating sheet? What are the categories? The following highlights.
In fact, since electric heaters are sought after by the market, various electrothermal film mica heating sheets have also been born in the world, which have been dubbed "electric film mica heating sheets" by various heating element manufacturers. The good and the bad are mixed, and the situation of fish and fish is mixed, giving consumers and applications
Finished products manufacturers are misleading, and even cause some misunderstandings about electrothermal film technology.
According to the core composition of its heating film, there are the following types, one by one:
(1) Wrapping alloy electric wire electric heating film
Since ancient times, it has been widely used as a more traditional heating method. Because the heating wire is a linear heat source, the heat dissipation area is small, and the heat radiation wave diffuses in three dimensions. Part of the electrical energy is converted into light energy, which is a strong flame. According to the law of energy conservation, the energy conversion efficiency is only 60% -70%.
The temperature rise can reach 1100 ℃, the heating wire is easy to break, and the seismic performance is poor.
The electric heating wire is made into electric heating wire, electric heating rod, electric heating plate, electric heating sheet by pressing, stretching, stretching and stretching, but it cannot be used for power cutting at will. The production technology of electric heating wire has been very mature. The supporting household appliances are mostly low-end products with low competitiveness. Some heating wires
It is difficult for home appliances to enter high-end markets such as Europe and the United States.
(2) Carbon film mica hot plate
Carbon film belongs to the category of electric heating film, and is an organic opaque electric heating film. Organic electrothermal film is composed of polymer electrothermal film and additive electrothermal film. At present, the most practical application is to add carbon black, graphite or a mixture of both to the film-forming material, commonly known as black film. The process of film formation
Coating and screen printing are commonly used. Most electrothermal films require a carrier for film formation and use. The most widely used carrier materials are glass, ceramics, and mica.
