Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antireflection film processing, in particular to an antireflection film spray coating device. Background Art
[0002] For the preparation of anti-reflection films for vacuum collector tubes and reflectors in medium and high temperature applications of solar thermal, the traditional coating method is the immersion and pulling method. The so-called immersion and pulling method is to immerse the cleaned substrate (outer glass tube) in a pre-prepared sol coating solution, and then steadily pull the substrate out of the sol at a uniform speed. Under the action of viscosity and gravity, a uniform liquid film will be coated on the surface of the substrate. As the solvent evaporates, the sol attached to the substrate will quickly gel to form a gel film. Finally, after proper curing, the corresponding anti-reflection film layer can be formed. However, this method is limited by the coating process and has very low production efficiency. It is difficult to significantly increase production capacity using this method, and the amount of anti-reflection film liquid added at one time is too large, which can easily lead to unstable performance of the anti-reflection film liquid or even serious damage to its life due to severe solvent volatilization, thereby causing great waste.
