Method for coating material application to substrate and device for coating material application

Abstract

The invention relates to a method for coating a material application to a substrate and a device for coating the material application. In order to thinly, uniformly and highly-efficiently coat the material application to surfaces of single or continuous glass or resin films, sheets and plates, the method and the device are provided. The method comprises providing the material application to a coating roll and then coating the material application to the surfaces of the conveying substrate through rotation of the coating roll, wherein the substrate is single or continuous. In a coating roll and a coating amount control roll in rotary contact with an outer surface of the coating roll, at least the coating amount control roll enables hydrophilic DLC film to form a film on surface of the roll. The coating amount control roll or a scraper is contacted with the coating roll, so as to coat the material application on the outer surface of the coating roll to be uniform and thin; and the outer surface is contacted with the conveying substrate through rotation of the coating roll, thereby coating the uniform and thin material application on the coating roll onto the substrate.

Description

technical field [0001] The present invention relates to a method capable of coating a paint at a thickness of nanometer (nm) units on the surface of a base material and a coating device using the method. Background technique [0002] In recent years, solar generators have become widely popular. Solar power generators have attracted attention as an alternative to nuclear power generators after the Great East Japan Earthquake. However, there is a limit to the power generation efficiency or productivity with current solar generators. One of the reasons is that the photo / electric conversion efficiency of the photo / electric conversion element is low. In addition, because the solar generator installed outside is often exposed to wind, rain or sand, scale and dust are accumulated on the front glass surface of the solar generator, which blocks sunlight, increases the refractive index, and deteriorates light transmission. become a major factor. [0003] In order to prevent contam...

AI Technical Summary

Problems solved by technology

Although the wear resistance of the substrate provided with the DLC film of Patent Documents 1 to 8 is improved, it lacks hydrophilicity due to its water repellency, and it is easy to cause uneven coating and uneven coating thickness. Therefore, even for The surface of the front glass of the solar generator should be formed with a resist film, and the anti-pollution and improvement of the refractive index of the front glass may not be sufficient.
