Embodiment
[0060] Such as figure 1 As shown, a heating device for side heating includes a cylindrical substrate 1 with an inner cavity, and an electrothermal film 2 is provided on the outer surface of the cylindrical side wall of the substrate 1. The electrothermal film 2 is composed of Made from the following components by weight:
[0061] Tin tetrachloride 30~50,
[0062] Titanium trichloride 0.8~1.2,
[0063] Antimony trichloride 12~18,
[0064] Calcium dichloride 1.5~2.5,
[0065] Chromium trioxide 0.8~1.2,
[0066] Manganese dioxide 0.8~1.2,
[0067] Nickel trioxide 0.8~1.2,
[0068] Isopropanol 8~12,
[0069] Ethanol 3~5,
[0070] Water 20~30;
[0071] The stability of the electric heating film 2 is improved by adding antimony, the temperature resistance of the electric heating film 2 is improved by adding titanium, the infrared emissivity of the electric heating film 2 is improved by adding nickel and manganese, and the electric heating film is improved by adding isopropa...
example 1
[0082] The electrothermal film 2 is made of the following components by weight:
[0083] Tin tetrachloride 40, titanium trichloride 1, antimony trichloride 15, calcium dichloride 2, chromium trioxide 1, manganese dioxide 1, nickel trioxide 1, isopropanol 10, ethanol 4, water 25;
[0084] Its preparation method is:
[0085] S1. Weigh each component according to the above weight ratio, mix the weighed components, and continue to stir until all the solids are dissolved and the components are mixed evenly to obtain the electrothermal film treatment solution;
[0086] S2. Transport the substrate 1 to the heating chamber, the temperature in the heating chamber is controlled at 600°C, after the substrate 1 is heated to 600°C, the electrothermal film treatment liquid is atomized and sprayed onto the bottom of the substrate 1 in the heating chamber through a spray gun The electrothermal film semi-finished product is formed on the surface, and the injection pressure of the electrother...
