In the construction industry, the problem of bubbles has always been a challenge faced by engineers and construction personnel in the production and construction process of materials such as concrete, gypsum, and coatings. These bubbles not only affect the appearance of the material, but also reduce its strength and durability, posing a potential threat to building safety. Defoamer, as a chemical additive that can effectively reduce or eliminate foam, plays a vital role in the construction industry.

In the production and construction process of building materials, foam is often generated from a variety of factors, such as the introduction of air in the mixing process, excessive moisture in raw materials or active ingredients of additives. The existence of foam will seriously affect the compactness, strength and stability of materials, and then affect the quality and safety of the entire building structure. Therefore, the use of defoamers has become an inevitable choice to control foam and improve building quality.

The commonly used defoamers in the construction industry mainly include organosilicon, polyether, and mineral oils. Organosilicon defoamers are widely favored for their efficient defoaming ability and good heat and acid alkali resistance; Polyether defoamers are widely used due to their good water solubility and compatibility with building materials; Mineral oil defoamers play a role in specific situations due to their lower cost and stable defoaming effect.

Taking concrete as an example, the application of concrete defoamers greatly improves the compactness and strength of concrete. Adding an appropriate amount of defoamer during the concrete mixing process can effectively reduce the generation of bubbles, make the concrete structure more compact, and thus improve its mechanical properties such as compressive strength and flexural strength. This not only helps to reduce construction costs, but also enhances the overall safety and durability of the building.

With the continuous development of the construction industry, the requirements for the performance of building materials are becoming increasingly high. The importance of defoamers as important auxiliary materials for improving the quality of building materials is self-evident. In the future, with the continuous advancement of technology and the improvement of environmental protection requirements, defoamers in the construction industry will become more environmentally friendly, efficient, and multifunctional, contributing greater strength to the development of the construction industry.
