We invite all experts to discuss together the defoaming issues of these water-based pastes.

The issue of eliminating the large number of bubbles generated during the operation of water-based dispersion liquid pastes through process means.
What specific slurry is it? Can an antifoaming agent be added? Emulsified silicone-based antifoamers are used; they provide rapid defoaming and are non-toxic.
Keep the operating temperature of the slurry from being too high, improve the filtration of the slurry, and add an antifoaming agent.
Defoamers can be used, but their effectiveness is not very good, and they cannot meet the requirements of high-speed coating; it is hoped that a combination of mechanical methods and defoamers can achieve the desired result.
:For the handshake process, just add an antifoaming agent; using an emulsified type will yield better results! Give it a try; if it doesn’t work, ask again!
Reply to 5# Lan Anji: I work with water-based paste coating, and the problem is that a large number of bubbles are generated during the recovery of the paste, and these bubbles are difficult to eliminate. I hope to gain a deeper understanding of this issue.
