In the construction industry, defoamers are widely used as key additives in the production of various building materials such as concrete, coatings, and gypsum boards. Their main function is to eliminate the foam generated in the production process, so as to improve the quality and stability of products. However, with the increasing global awareness of environmental protection, the construction industry is also actively seeking greener and more environmentally friendly defoamer solutions. 1、 Environmental regulations promote the development of green defoamers

In recent years, governments around the world have introduced strict environmental regulations to limit the emission of harmful substances and promote the greening of building materials. This places higher demands on the production and use of defoamers in the construction industry. Traditional defoamers often contain harmful chemical components to the environment, such as silicone oil, mineral oil, etc. These components are difficult to degrade in the natural environment and cause pollution to soil and water bodies. Therefore, developing environmentally friendly defoamers to reduce the emission of harmful substances has become an inevitable trend for the future development of defoamers in the construction industry.

2、 Innovative research and development of green defoamers

In order to achieve the green development of defoamers, researchers are actively developing new environmentally friendly defoamers. These defoamers mainly use natural or renewable resources as raw materials, such as vegetable oils, biobased materials, etc. These raw materials have good biodegradability and are environmentally friendly. At the same time, researchers have improved production processes and formulations to enhance the stability and defoaming efficiency of defoamers, in order to meet the demand for high-performance defoamers in the construction industry.

3、 Application Practice of Green Defoamer

In the construction industry, the application of green defoamers is gradually expanding. For example, in concrete production, the use of environmentally friendly defoamers can reduce the generation of bubbles, improve the compactness and strength of concrete. This not only improves the quality of concrete, but also reduces the amount of raw materials such as cement and lowers production costs. At the same time, the use of environmentally friendly defoamers can also reduce energy consumption and emissions during the production process, which is in line with the concept of green buildings.

Green defoamers also play an important role in the production of coatings and gypsum boards. They can eliminate the foam produced during the production of paint and gypsum board, and improve the flatness and beauty of products. In addition, environmentally friendly defoamers can also reduce the emission of harmful substances in coatings and gypsum boards, making them more environmentally and human health friendly.

With the increasing awareness of environmental protection, researchers will continue to explore more environmentally friendly raw materials, such as natural vegetable oils, bio based materials, etc., to replace traditional harmful chemical components. Green defoamers not only need to have good environmental performance, but also need to have efficient and stable defoaming effects. Researchers will continue to improve production processes and formulas to enhance the stability and defoaming efficiency of defoamers. With the popularization of green building concepts, the application fields of green defoamers will continue to expand. In addition to the construction industry, they will also be widely used in other fields that require defoaming, such as chemical, food, and pharmaceutical industries. In the future, the production and management of defoamers in the construction industry will be more intelligent. By introducing advanced production equipment and management systems, the automation and intelligence of the production process can be achieved, improving production efficiency and product quality.

The green development of defoamers in the construction industry is an important part of achieving sustainable development in the construction industry. By developing environmentally friendly defoamers, improving production processes and formulas, expanding application areas, and achieving intelligent production and management, we can promote the green development of defoamers in the construction industry and contribute to the sustainable development of the construction industry. At the same time, this will also promote the green transformation and sustainable development of the entire society.
