Method for getting and distributing powder in ceramic laser distributing process and powder distributing device

Abstract

The invention provides a method for getting and distributing powder in a ceramic laser distributing process and a powder distributing device. During a power getting process, first, a charged photosensitive surface on the powder distributing device used for drawing powder is subjected to laser exposure, so that a ceramic pattern can be formed on the photosensitive surface; second, powder distributing device draws power; third, after the powder drawing action is finished, due to a principle that like charges repel each other, the powder distributing device distributes powder to a ceramic tile blank by releasing the powder adhered to the photosensitive surface to the ceramic tile blank through loading charges having the same electrical property with the powder on the photosensitive surface. The powder distributing device is provided with a photosensitive surface layer, an insulation layer and a powder drawing piece of an electrode layer, wherein the insulation layer is disposed between the photosensitive surface layer and the electrode layer. According to the scheme, the ceramic laser printing and distributing method is adopted. The textures of ceramic tiles are improved.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a method for retrieving and distributing powder in ceramic laser distributing and a powder distributing device. Background technique [0002] At present, in the production process of ceramic buildings, inkjet printing technology is used to make ceramic fabrics. Its working principle is that the lubricated fine ink droplets adhere to the surface of the medium to form graphics after being heated by the nozzle at high temperature; but in the production of architectural ceramics, it is mainly used The current inkjet printing is thermal inkjet printing, its disadvantage is that the ink will be heated during use, and the ink is prone to chemical changes at high temperatures, and its properties are unstable, so the authenticity of the printed colors will be affected to a certain extent; On the one hand, since the ink is ejected through air bubbles, the directionality and volu...
