山東Nanomembrane quartz heating tube 13.2x180mm

Electrothermal film is a conductive film, usually it and a good insulating thermal conductivity (such as quartz glass, ceramics, etc.) through high temperature sintering of the coating process as a whole, forming a film on the surface of the insulating thermal conductivity (that is, inorganic conductive resistance film), when the current passes along the direction of the film surface, the film is heated, is a surface resistive heating medium.

Nano-film quartz heating tube is a specific application of high temperature nano-semiconductor electrothermal film technology. Good insulating thermal conductivity ---- quartz glass tube (or sheet, etc.) is used as the substrate of the electrothermal film carrier, which makes full use of the quartz glass tube's excellent physical and chemical properties such as high temperature resistance and corrosion resistance.
