Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass etching, specifically to a PTFE foaming frame for glass etching. Background Technology
[0002] Glass etching is a glass processing technique that alters the surface properties of glass through chemical reactions. It primarily involves placing the glass in an etching bath filled with etching solution for the reaction. Hydrofluoric acid is commonly used as the etchant. Glass etching technology is widely used in industrial glass production and glass art. With technological advancements, glass etching has also become an important part of the electronics industry. Simultaneously, the requirements for surface etching uniformity in industrial production are becoming increasingly stringent. Polytetrafluoroethylene (PTFE), also known as Teflon, is a high-molecular-weight polymer with acid and alkali resistance, capable of resisting the erosion of substances such as hydrofluoric acid.
[0003] Currently, in the glass etching process, residues are generated during the chemical reaction between the glass surface and the etchant. These residues adhere to and accumulate on the glass surface, affecting the further reaction between the glass surface and the etchant, thus leading to uneven etching of the glass surface.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Example 1
[0020] Please see Figures 1-4This utility model provides a technical solution for a glass-etched PTFE foaming frame: It includes a support portion, which includes a fixed plate 1. A support column 2 is fixedly connected to the upper surface of the fixed plate 1, and a top plate 3 is fixedly connected to the other end of the support column 2. An air guiding portion is provided inside the support portion; the air guiding portion includes an air column 6, with an air supply pipe 4 connected above the air column 6. One end of the air column 6 is fixedly connected to the fixed plate 1, and the other end of the air column 6 is fixedly connected to the top plate 3. An air inlet 5 is connected to the other end of the air supply pipe 4, and an air outlet is provided on the surface of the air column 6. 10. The air outlet 10 is connected to the inside of the air column 6. The outer surface of the air outlet 10 is fitted with a gas guide tube 13, which is connected to the inside of the air outlet 10. The other end of the gas guide tube 13 is provided with a foaming part. The air column 6 is provided to further transport the compressed gas input from the air supply pipe 4 into the gas guide tube 13. The gas guide tube 13 is provided to connect with the foaming tube 8 to form ten sets of longitudinally arranged foaming devices, so that the dense bubbles generated by the foaming tube 8 can cover the entire etching environment, thereby ensuring the uniformity of the etching reaction.
[0021] Example 2
[0022] Based on Embodiment 1, the foaming part includes a foaming support 9, which has a foaming fixing port 14 inside. A foaming tube 8 is sleeved inside the foaming fixing port 14. Both ends of the foaming tube 8 are connected to the air guide pipe 13. One end of the foaming support 9 is fixedly connected to the fixing plate 1, and the other end of the foaming support 9 is fixedly connected to the top plate 3. A positioning port 7 is provided inside the fixing plate 1. The purpose of setting the foaming support 9 is to limit the foaming tube 8 to the working position through the foaming fixing port 14 inside, and to evenly arrange the multiple foaming devices composed of the foaming tube 8 and the air guide pipe 13. The positioning port 7 is provided to determine the placement position of the foaming frame at the bottom of the etching pool.
[0023] Example 3
[0024] Based on Embodiment 2, two foaming supports 9 are provided, and the foaming supports 9 are fixedly connected by a horizontal plate 11. Both ends of the foaming tube 8 are fixedly connected with sealing rings 12. The sealing rings 12 are sleeved with one end of the air guide tube 13. The surface of the foaming tube 8 is provided with small air holes, which are connected to the inside of the foaming tube 8. Ten foaming tubes 8 are provided. The sealing rings 12 are provided to ensure the airtightness when the foaming tube 8 and the air guide tube 13 are connected. The small air holes are provided to discharge the compressed gas input into the foaming tube 8 into the etching solution in the form of dense bubbles to achieve the foaming effect, drive the etching solution to react with the glass surface, and at the same time carry away the residue generated after the reaction, so that the glass surface and the etching solution can react further.
[0025] In actual use, before operation, the PTFE foaming frame for glass etching is positioned in the designated position in the etching pool through the positioning port 7. The glass to be etched and the etching solution are then placed in the working position of the etching pool for etching reaction. The foaming frame is made entirely of PTFE, which can resist the erosion of the etching solution. Compressed gas is input into the device through the air inlet 5. The gas enters the air column 6 through the air supply pipe 4, and then the air column 6 distributes the gas into the air guide pipe 13, and then into the interior of the foaming tube 8. After passing through the tiny pores on the surface of the foaming tube 8, the gas forms dense bubbles in the etching solution. These bubbles move upward in the etching solution, driving the etching solution to fully react with the glass surface. At the same time, the residue formed by the etching reaction on the glass surface is washed away and peeled off, allowing the glass surface to further react with the etching solution, thereby ensuring the etching uniformity of the glass surface.
