| titleOfInvention | A manufacturing process for screen glass using a both as writing board and image projection |
| abstract | The present invention relates to a method of manufacturing a screen glass for both image projection and blackboard, and a method for manufacturing the screen glass comprises the steps of: preparing a disc glass from 1 to 20% by weight of hydrofluoric acid, 0.1 to 5% by weight of ammonium fluoride, A first step of immersing the composition in a glass reinforcing composition comprising water so that the total weight of the composition is 1 wt% to 10 wt%, and the total weight of the total composition is 100 wt%; The entire surface of a separable glass substrate having a thickness of 2 to 10 mm was sandblasted with sand or gold stones having a particle size of 200 to 1500 mesh and then subjected to corrosion treatment with an acid solution one to three times to obtain a polished glass having a degree of gloss of 5 to 60 and a surface roughness of 0.05 A second step of forming a low reflection uneven surface having a thickness of about 1.0 mu m; A third step of forming a screen layer by coating synthetic resin for paint having a content of pearl powder of 5 to 30 wt% in the thickness of 30 to 60 탆 on the rear surface of the separator glass substrate; And a fourth step of forming an adhesive layer on the rim of the screen layer and placing and bonding an anti-reflection sheet glass on which an anti-reflection uneven surface is formed, on the adhesive layer. Accordingly, it is possible to simultaneously use the screen glass as a screen glass without separately purchasing a screen necessary for image realization, thereby reducing the economic burden on the user, and also providing an efficient operation space for a screen and a blackboard. |
