With the increasing global awareness of environmental protection, the construction industry is facing a green revolution. As an important additive in building materials, the greening process of defoamers is particularly important.

Traditional defoamers, such as organosilicon and mineral oils, play an important role in building materials, but the environmental issues that exist during their production and use cannot be ignored. These defoamers are often difficult to degrade and cause long-term pollution to the environment. Therefore, finding environmentally friendly and biodegradable alternatives has become the primary task for the green development of defoamers in the construction industry.

In recent years, with the advancement of technology and the improvement of environmental awareness, significant progress has been made in the research and development of green defoamers.

Biobased defoamers: defoamers prepared using renewable resources such as vegetable oil, starch, etc. have the characteristics of environmental protection and biodegradability.

Nanodefoamers: Defoamers prepared through nanotechnology have the advantages of high efficiency, low toxicity, and easy degradation, and are an important development direction for future green defoamers.

Water based defoamer: A defoamer that uses water as a solvent, is non-toxic, harmless, and easy to handle, meeting environmental requirements.

The market prospect of green defoamers is broad, but their development also faces many challenges. The production cost of green defoamers is usually high, and it needs to be reduced through technological innovation and large-scale production. Green defoamers need to meet the requirements of building materials for defoaming performance, stability, and other aspects. The government needs to introduce relevant policies to encourage the research and use of green defoamers, and promote the green development of the construction industry.

The green development of defoamers in the construction industry is an important component of the green revolution in the construction industry. Through technological innovation and policy guidance, green defoamers will gradually replace traditional defoamers and become the mainstream choice in the construction industry.
