In the construction industry, there are countless application cases of defoamers, and their effects vary. By analyzing these application cases, we can better understand the role and value of defoamers in the construction industry.

In the process of concrete production, the presence of bubbles can lead to a decrease in the density of concrete, thereby affecting its strength and durability. A certain concrete production enterprise has successfully reduced the number of bubbles in concrete and improved the density and strength of concrete by using defoamers. After testing, the use of defoamers has increased the strength of concrete by about 10%, and at the same time, the appearance of concrete is smoother, improving the overall performance of building structures.

Bubbles in the coating can affect its film-forming effect and glossiness, thereby affecting the overall quality of the coating. A certain paint production enterprise successfully eliminated bubbles in the paint by using defoamers, improving the film-forming effect and glossiness of the paint. At the same time, the use of defoamers also reduces the surface tension of the coating, making it easier to apply and dry. These improvements not only improve the quality of coatings, but also reduce production costs and construction difficulties.

Bubbles in gypsum board can cause a decrease in its strength and an increase in its fragility. A certain gypsum board production enterprise has successfully reduced the number of bubbles in gypsum board and improved its strength and stability by using defoamers. After testing, the use of defoamers has increased the strength of gypsum boards by about 20%. At the same time, the surface of gypsum boards is smoother and more even, improving their aesthetics and service life.

Through the analysis of these application cases, we can find that defoamers have a wide range of application value and significant effects in the construction industry. Defoamers can not only improve the performance and stability of building materials, but also reduce production costs and construction difficulties, providing strong support for the development of the construction industry.
