In modern construction industry, bubble problem has always been a key factor affecting material performance and construction quality. From concrete, gypsum to various building coatings, the presence of bubbles not only affects the appearance of materials, but also significantly reduces their strength and durability, thereby threatening the overall quality and safety of buildings. Therefore, as an important additive, defoamers in the construction industry play an indispensable role in building construction and material manufacturing.

As the foundation material of buildings, the performance of concrete directly affects the quality and service life of buildings. However, in the production and construction process of concrete, the problem of bubbles has always been a challenge faced by engineers and construction personnel. Bubbles in concrete not only reduce its density, but also increase the channels for moisture and harmful substances to penetrate, thereby shortening the service life of concrete. The emergence of concrete defoamers provides an effective solution to this problem. It can quickly eliminate bubbles in concrete through unique chemical reactions, making the structure of concrete more compact and its performance more superior. Experimental data shows that the compressive strength and flexural strength of concrete treated with defoamers have significantly improved. This means that under the same design requirements, fewer materials can be used to achieve the same strength standards, thereby reducing construction costs. In addition, concrete defoamers can effectively improve the durability of concrete and extend its service life, especially in harsh environmental conditions such as marine engineering and chemical construction, where their role is more prominent.

Gypsum products are also widely used in the construction industry, such as gypsum boards, gypsum lines, gypsum statues, etc. However, in the production process of gypsum, due to the improper proportion of raw materials, chemical additives added in the processing process and air contact and other reasons, a large number of foam is often produced. These foam will not only affect the appearance quality of gypsum products, but also increase the production difficulty and cost and reduce the market competitiveness of products. Gypsum defoamer is a special additive developed to solve the foam problem in the production of gypsum products. It can effectively inhibit and eliminate foam in gypsum, make the surface of gypsum products more smooth and improve the appearance quality of products. At the same time, gypsum defoamers can also improve the physical properties of gypsum products, such as increasing compressive strength, flexural strength, and durability, thereby comprehensively improving the quality of products.

Polycarboxylate defoamer is a new type of defoamer in the construction industry, mainly used in the production of building materials such as polycarboxylate water reducers, waterproofing agents, and environmentally friendly concrete admixtures. Polycarboxylate defoamers are mainly composed of modified polyether substances, refined through special processes, and have the characteristics of chemical stability and resistance to environmental influences. Especially in low-temperature environments, polycarboxylate defoamers can still maintain excellent defoaming performance and are suitable for use in sub zero areas. Polycarboxylic acid defoamer can not only effectively eliminate foam in building materials, but also improve the stability and durability of materials. Adding polycarboxylic acid defoamer to polycarboxylic acid water reducer can significantly reduce the production of foam during concrete mixing, and improve the fluidity and uniformity of concrete. Meanwhile, polycarboxylate defoamers can enhance the effectiveness of waterproofing agents and improve the waterproof performance of buildings. Adding polycarboxylate defoamers to environmentally friendly concrete admixtures can ensure concrete performance while reducing environmental impact, meeting the requirements of green buildings.

In summary, defoamers in the construction industry play an important role in improving the performance of building materials and construction quality. With the continuous development of the construction industry and the advancement of technology, we believe that in the future, more high-performance, environmentally friendly and energy-saving defoamers will emerge in the construction industry, contributing to the sustainable development of the construction industry.
