Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, and more specifically to a defoaming device for water-based coating production. Background Art

[0002] Any paint that uses water as a solvent or dispersion medium can be called a water-based paint. Water-based paint has excellent non-stickiness and durability. Water-based paint uses water as a solvent, saving a lot of resources. Water-based paint eliminates the risk of fire during construction and reduces air pollution. During the production and use of water-based paint, a large number of bubbles will be generated, affecting the quality and appearance of the paint. Therefore, a defoaming agent is needed to remove the bubbles.

[0003] For example, a reaction device for producing water-based paint with patent publication number CN219898127U includes a reactor, a stirring mechanism, a first defoaming mechanism and a second defoaming mechanism, wherein the stirring mechanism is located inside the reactor, the first defoaming mechanism is located inside the reactor, the second defoaming mechanism is located at the upper end of the reactor, and the first defoaming mechanism includes a connecting plate, a vibrating rod, a fastening bolt and a fastening nut.
