Description
Technical Field
The invention relates to the technical field of glass coating, in particular to a film removing method for coated glass.
Background
With social progress and technical development, coated glass is widely applied to the glass deep processing industry, hollow glass and laminated glass are main forms of glass deep processing products, and the coated glass is used for synthesizing the hollow glass or the laminated glass. When the coated glass is prepared, the film of the edge of the glass to be coated is usually removed, so that when the prepared coated glass is synthesized into hollow glass or laminated glass, the gluing and edge sealing quality of the hollow glass or the laminated glass can be ensured, and the common defects of glue failure, bubbles and the like caused by poor edge sealing strength are avoided.
As shown in fig. 1, which is one of the schematic structural diagrams of the glass to be coated, the glass to be coated is divided into a coating area and a film removing area, wherein the coating area is an area on the glass to be coated that needs to be subjected to a coating process, the film removing area is an area on the glass to be coated that needs to be subjected to a film removing process after the coating process is completed, and the film removing process is performed on the area on the glass to be coated that needs to be subjected to a film removing process after the coating process is performed on the area on the glass to be coated, so as to form the coated glass.
The method mainly comprises three methods for removing the film of the film removing area on the glass to be coated, namely mechanical film removal, low-temperature ink film coating film removal and shielding plate covering of the film removing area.
The mechanical membrane removal can generate dust and noise, and can affect the product quality, the health of production personnel and the production environment to a certain extent; when a film needs to be removed from a specific part except the edge part, such as the edge of a through hole in the middle of a glass plate, within a range of 0.5-4 cm away from the edge, the operation of mechanical film removing equipment is difficult, the film surface is easily damaged additionally, and the product quality is influenced.
When the method of low-temperature ink film coating is adopted to remove the film of the toughened glass, because the removal of the low-temperature ink requires higher temperature, the glass is generally subjected to film coating treatment firstly, then the ink is removed while the glass is toughened, but the flatness of the product is easily influenced by adopting the process of firstly coating the film and then toughening the glass. If the glass is firstly toughened and then coated, the glass needs to be heated twice at high temperature, which is easy to affect the performance of the glass.
When the film removing area is covered by the shielding plate for film removing, the shielding plate is generally a metal shielding plate or a plastic shielding plate, and the thickness of the shielding plate is controlled to be in millimeter level in order to prevent the shielding plate from deforming in the using process, but when the shielding plate with millimeter thickness is used for film coating, an edge effect is generated, and the edge of the coated film generates color difference.
