Description

Technical Field

[0001] The utility model relates to a stirring device, in particular to a stirring device for etching liquid production, belonging to the technical field of etching liquid processing. Background Art

[0002] Etching liquid is a chemical reaction for etching or etching on the surface of materials, and is used in the production of circuit boards, micro-processing and artworks. The composition and use of etching liquid will vary according to specific application fields and needs. In the processing of etching liquid, a stirring device is required to evenly mix the components in the etching liquid to ensure the consistency and stability of the etching effect.

[0003] However, the existing etching liquid stirring devices mostly use a single stirring rod to stir the etching liquid. The single stirring rod may not be able to overcome the rotational inertia of the liquid during the stirring process, and the liquid cannot be fully mixed, resulting in local concentration differences and reduced stirring effect; at the same time, wall hanging is prone to occur during the stirring process of the etching liquid. Wall hanging will cause the local flow rate of the etching liquid near the container wall to change, thereby making the contact between the reactant and the reactant uneven, affecting the uniformity of the etching liquid, and because the concentration of the reactant at the wall hanging is high, it may cause an overly fast reaction in these areas, while there is a problem of too slow reaction rate in other areas, and it may also cause wear to the stirring device itself, reducing the service life of the equipment.

[0004] Therefore, a stirring device for producing etching liquid is proposed. Utility Model Content
