Abstract

The invention provides an electrothermal film, which is prepared from tin tetrachloride, antimony chloride, chromium trichloride, gallium chloride and germanium chloride. The invention also provides a coating process and a vapor deposition device. The electrothermal film solves the technical problems that an electrothermal film layer has non-uniform resistance, uneven heat in the process of heating, lower electro-thermal conversion efficiency and short service life of the electrothermal film in the prior art, and simultaneously the technical problem that the unity of the resistance is difficult to control by the conventional electrothermal film production process. Compared with the electrothermal film in the prior art, the electrothermal film of the invention can ensure that the resistance is uniform, the resistance value can be controlled, and insusceptibility to burning and long service life can be achieved; and the adhesiveness of the electrothermal film is greatly improved, no shedding and attenuation, and long service life are ensured, so the electrical property is greatly improved and application range of the electrothermal film is greatly widen.

Description

Technical field: [0001] The invention relates to the field of electricity, in particular to an electrothermal film, in particular to an electrothermal film and a coating process and device. Background technique: [0002] In the prior art, electric heating wires are widely used to heat liquids, but the electric heating wires are not close to the object to be heated due to the small heat dissipation surface. During the electrothermal conversion process, the heat generated by electric energy cannot be quickly transferred to the heated object, resulting in electric heating. The heat on the component is too concentrated, and the component itself becomes hot quickly, so that a large part of the electric energy becomes light energy and is lost, resulting in low electrothermal conversion efficiency. In addition, the general heating wire is always used in a hot state, so it is easy to oxidize, resulting in open circuit and short life. In the prior art, electrothermal film is also us...
