In the construction industry, in the production process of various building materials such as cement mortar, concrete, gypsum board, etc., a large number of foam are often produced due to physical actions such as mixing and vibration. These foam will not only affect the uniformity and stability of materials, but also reduce the strength and durability of products, thus affecting the overall quality of buildings. Therefore, the use of defoamers in the construction industry has become crucial.

Defoamers in the construction industry are mainly used to destroy the stability of foam, so that bubbles can break and dissipate rapidly. Common defoamers in the construction industry include modified polyethers, lipophilic compounds, and high carbon alcohol substances, which are made through special processes and have excellent defoaming and anti foaming properties.

In the production process of cement mortar, defoamer can effectively reduce the amount of foam, make the cement mortar more uniform, thus improving its strength and durability. In the production of concrete, defoamers can also play an important role in reducing bubbles in the concrete, improving its compactness and compressive strength. In addition, the application of defoamers is also indispensable in the production of building materials such as gypsum board and putty powder.

The application of defoamers in the construction industry is not limited to the production stage, but can also be used for defoaming during the construction process. For example, in the process of wall painting, defoamers can effectively reduce bubbles in the paint, making the wall surface smoother and improving its aesthetics and durability.

Choosing the appropriate defoamer for the construction industry is crucial for ensuring the quality of building materials and the overall quality of the building. When choosing defoamers, factors such as the type of material, production process, performance, and environmental friendliness of the defoamer need to be considered.
