Description

Technical Field

[0001] The utility model relates to the technical field of plastic part processing, in particular to a device for micro-etching and roughening the surface of a plastic part. Background Art

[0002] Micro-etching and roughening the surface of plastic parts is a technique used to improve the surface properties of plastic parts, especially when subsequent treatments such as coating, plating, or bonding are required. This treatment removes some surface material, thereby increasing surface roughness and reactivity, improving adhesion to other materials. Typical treatment methods include chemical etching: Acid etching: Etching the plastic surface with an acidic solution (such as sulfuric acid or hydrofluoric acid). The acid dissolves certain components of the plastic surface, creating a roughened surface. Alkaline etching: Etching with an alkaline solution (such as sodium hydroxide) is suitable for certain types of plastics. Physical methods: Sandblasting: Using a sandblaster to spray fine particles (such as sand or glass beads) onto the plastic surface, physically grinding and creating a rough surface. Sanding: Mechanically grinding the surface (such as sandpaper or grinding wheels) to increase surface roughness. Plasma treatment: Plasma etching: Using plasma in a low-pressure environment to treat the plastic surface, removing organic matter and increasing surface roughness.

[0003] In the prior art, when chemical etching is used to roughen the surface of plastic parts, the existing processing equipment simply immerses and etches the plastic parts in a processing box filled with an acidic solution (such as sulfuric acid, hydrofluoric acid, etc.) or an alkaline solution (such as sodium hydroxide). This is inefficient and it is inconvenient to remove the treated plastic parts from the processing box. Therefore, we propose a plastic part surface roughening processing equipment to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the processing equipment existing in the prior art only performs immersion etching by placing the plastic parts in a processing box injected with an acidic solution (such as sulfuric acid, hydrofluoric acid, etc.) or an alkaline solution (such as sodium hydroxide), which is inefficient and inconvenient to remove the treated plastic parts from the processing box. The present utility model proposes a plastic part surface micro-etching and roughening processing equipment.
