Abstract

The invention discloses a heating apparatus for heating a bottom and a top simultaneously. The heating apparatus comprises an upper base body (1) and a lower base body (2), wherein the upper base body and the lower base body are arranged oppositely in an up-down mode; and electrothermal films (3) are arranged at the upper surface of the upper base body (1) and the lower surface of the lower base body (2). The electrothermal films are formed by the components of stannic chloride, titanium trichloride, antimony trichloride, calcium chloride, chromic oxide, manganese dioxide, nickelic trioxide, isopropanol, ethanol, and water. After the components are mixed to prepare electrothermal film treating fluid, the electrothermal film treating fluid is sprayed and coated on the surfaces of the heated base bodies; annealing is carried out; and then electrode processing is carried out to obtain electrothermal film finished products. In addition, the invention also discloses a method for carrying out heating by using the heating apparatus. The apparatus and method have the following beneficial effects: shedding is prevented; the upper limit of the temperature of the electrothermal film is enhanced, so that the temperature of the heating base body can rise rapidly; and the maximum surface working temperature can reach 800 to 1000 DEG C, the highest power density can reach 40W / cm<2>, and the service life can reach over 30000 hours.

Description

technical field [0001] The invention relates to the technical field of electrothermal film heating devices, in particular to a heating device and a heating method for simultaneously heating the bottom and the top. Background technique [0002] Most of the electric heating film in the prior art has the surface temperature of the electric heating film is too low, it is difficult to realize the electric heating film technology in the high temperature stage, and it is only suitable for the working conditions of low temperature and slow heating; moreover, its heating performance is unstable, and it can be used for a long time. During the working process of time use, the heating power is easy to attenuate; the adhesion between the electric heating film and the substrate is poor, it is easy to fall off, and the actual service life is short. [0003] In addition, the electric heating film variable power heating technology in the prior art, such as a multi-power energy-saving electri...
