As the cornerstone of the construction industry, the performance of concrete directly affects the quality and durability of buildings. During the preparation and construction of concrete, the generation of bubbles often affects the strength and appearance quality of the concrete. This article discusses in detail the application scenarios of defoamers in concrete, including the selection principles of different types of defoamers, the control of addition timing, and their specific effects on concrete performance. At the same time, it also analyzed how to further improve the construction efficiency and quality of concrete by optimizing the use strategy of defoamers.

As an important material for beautifying the appearance and protecting the structure of buildings, architectural coatings often produce bubbles during the construction process due to various reasons, which affect the coating effect and durability. This article delves into the principles of defoaming technology in architectural coatings and analyzes the fundamental causes and influencing factors of bubble formation. Targeted defoaming solutions have been proposed for different types of architectural coatings, including selecting appropriate defoamer types, adjusting construction processes, and optimizing coating formulations. In addition, the development trend of defoaming technology in the future architectural coatings industry was also discussed.
