Title

(EN) SURFACE ROUGHENING METHOD FOR TRANSPARENT MATERIAL WITH SMOOTH SURFACE

(FR) PROCÉDÉ DE RUGOSIFICATION DE SURFACE POUR MATÉRIAU TRANSPARENT À SURFACE LISSE

Abstract

(EN) The present invention discloses a surface roughening method for a transparent material with a smooth surface, which includes the following steps: A coating is arranged on one side surface of the transparent material, and an intense light pulse is applied on the other side surface of the transparent material, utilizing the intense light pulse to pass through the transparent material to reach the coating; and a clean, highly transparent and rough surface is formed on the side surface of the transparent material originally provided with the coating. The present invention effectively realizes the roughening of the smooth surface of the transparent material, and avoids the technical disadvantages of glass surface etching, machining (such as sandblasting), laser machining and other processes in the prior art.

(FR) La présente invention concerne un procédé de rugosification de surface pour un matériau transparent ayant une surface lisse, qui comprend les étapes suivantes : Un revêtement est disposé sur une surface latérale du matériau transparent et une impulsion de lumière intense est appliquée sur l'autre surface latérale du matériau transparent à l'aide de l'impulsion de lumière intense pour passer à travers le matériau transparent afin d'atteindre le revêtement ; et une surface propre, hautement transparente et rugueuse est formée sur la surface latérale du matériau transparent pourvu à l'origine du revêtement. La présente invention réalise efficacement la rugosification de la surface lisse du matériau transparent et évite les inconvénients techniques de la gravure de surface de verre, de l'usinage (tel que le sablage), de l'usinage au laser et d'autres procédés dans l'état de la technique.
