Embodiment Construction

[0014] In order to facilitate the understanding of those skilled in the art, the present invention will be described in further detail below in conjunction with specific embodiments:

[0015] The electric heating film that present embodiment provides is by weight ratio, and its composition is:

[0016] Tin tetrachloride: 33%, titanium tetrachloride: 30%, calcium dichloride: 0.3%, bismuth trichloride: 0.2%, ethanol: 30%, water: 6.5%.

[0017] According to the above proportions, when making: first, put tin tetrachloride, titanium tetrachloride, calcium dichloride, bismuth trichloride, ethanol, and water into a mixing heater and heat them together, and the heating temperature is controlled at 65-75 degrees Celsius In between, stir evenly to completely dissolve the solid components and cool to room temperature; then filter the dissolved mixed solution to obtain a treatment solution; then spray the treatment solution on the surface of the electrothermal film carrier through a negat...

Abstract

The invention discloses an electric heating membrane comprising the following components in percent by weight: 20-40 percent of stannic chloride, 25-35 percent of titanium tetrachloride, 0.2-0.3 percent of calcium chloride dihydrate, 0.1-0.3 percent of bismuth trichloride, 20-40 percent of alcohol and 5-7 percent of water. The invention has the advantages of high heat efficiency, stronger physical and chemical properties, suitability for various environments, no oxidation or ageing phenomena after being heated, convenience for production, high yield, capability of being made into various forms according to the requirement of carrier shapes and convenience for application.

Description

technical field [0001] The invention relates to semiconductor heating technology, in particular to an electrothermal film and a manufacturing method of the electrothermal film. Background technique [0002] Electric heating film is a new type of heating element. Compared with the commonly used heating forms such as resistance wire and infrared ray, it has the advantages of high heating efficiency, fast heating speed, not easy to aging, and long service life. However, due to the defects in the composition and the manufacturing method, the existing electrothermal film still has the disadvantages of instability, low product yield, etc., so it is difficult to be widely used. Contents of the invention [0003] One of the technical problems to be solved by the present invention is to provide an electrothermal film with stable quality, high production pass rate and suitable for various environments. [0004] In order to solve the above-mentioned technical problems, the present i...
