Preface
With the development of eletrothermal film technology and the continuous use of new materials, electrothermal film heating technology has been successfully used in water dispensers. The substrate material is made of non-metallic materl, which is attached with a layer of heating material (electrothermal film) through high temperature sintering. Because nonmetals are natural insulating materials, water and electricity are completely separated in a true sense. Its stable physical properties will not react with calcium and magnesium ions in the water to produce scale.
The power characteristics of electrothermal film
With high strength, high temperature resistant quartz glass tube as substrate material, the various chemical elements and compounds are spraying on the outer surface of the quartz glass tube, and then the electrothermal coatings in the form of ion and quartz tube base material physical and chemical reaction, generate the ionic bond and atomic bonds as the main body of new material, seeping into the quartz substrate surface lattice, By changing the chemical structure and properties of the surface layer of the insulation substrate, a kind of conductive heating layer with semiconductor characteristics is formed, and a new type of planar electrothermal conversion material is formed. Due to the complementarity of valence electron affinity and the mechanism of carrier form, the selection of different elements or compounds as the main material and the configuration of surface modifier break through the limitation of electrothermal film formulation, and greatly improve the thermal stability and the applicable temperature range of electrothermal elements.
When the electric heating film electrode of the quartz glass tube is connected to the power supply, the heating layer of the electric heating film rapidly heats up, and the high temperature generated by the heating layer heats the drinking water of the quartz tube to the service temperature in a very short time. Quartz has high hardness, strong thermal conductivity, sudden cooling and sudden heat resistance, and has the lowest coefficient of expansion among all non-metals. As the material of water fountain heating element, it is the best medium in terms of safety and heat conduction. Quartz glass tube itself acid and alkali resistance, no corrosion, no oxidation and other non-metallic characteristics, determines that it has no rust, not easy to scale, clean, health, safety and other advantages.
