Meanwhile, since the heating layer 30 has a whole-layer structure and completely covers the ir coating layer 20, the heating layer 30 can reduce the energy radiated from the ir coating layer 20, thereby improving the energy utilization of the ir coating layer 20.
However, in preparing the infrared coating, the inventors have found that the surface of the infrared coating prepared by the conventional technique and the present invention is generally rough and uneven, the infrared coating is porous, and the emissivity of the infrared coating is greater than or equal to 0.9. When the surface of the infrared coating is flat and has no porous structure, in the process of preparing the heating layer on the surface of the infrared coating, when particles vertically enter the surface of the infrared coating, the diffusion effect takes the dominant role, and the heating layer can grow into a uniform and compact structure; when the surface of the infrared coating is rough and has a porous structure, along with the increase of the incident angle of the particles, the shadow effect is enhanced and replaces the diffusion effect to take the leading role, the particles are blocked by the nano columns and the atomic clusters, and the diffusion is limited, the enhancement of the shadow effect can enable the incident particles to be easily deposited at the topmost end of the infrared coating, the heating layer becomes very loose, and the gaps among the nano columns are larger and larger, so that the phenomena of lower density, smaller binding force, poorer thickness uniformity, enhanced surface Raman scattering and the like can be easily generated in the deposition of the heating layer on the infrared coating with rough uneven surface. Therefore, the inventor further improves the first embodiment of the present invention to obtain a second embodiment.
