Electrothermal film is a conductive film, usually with good insulation conductors (such as quartz glass, ceramic, etc.) through high heat sintering coating process combined into an organic whole, form a thin film on the surface of the insulated conductors (i.e., inorganic conductive film resistance), and when the current direction along the membrane surface when the thin film by fever, is a kind of planar resistive heating medium.
Nano-film quartz heating tube is a specific application of high-temperature nano-semiconductor electrothermal film technology. It USES a good insulating thermal conductor -- quartz glass tube (or sheet, etc.) as the substrate of the electrothermal film carrier, which makes full use of the excellent physical and chemical properties such as high temperature resistance and corrosion resistance of quartz glass tube.
