With the increasing global awareness of environmental protection and the deepening of sustainable development concepts, the green development of defoamers in the construction industry has become a hot topic of industry concern. In the future, defoamers in the construction industry will pay more attention to the environmental friendliness of raw materials. Non toxic, harmless, and biodegradable raw materials will become mainstream to reduce environmental pollution.

While pursuing defoaming effects, future defoamers will pay more attention to efficiency and energy saving. By optimizing the formula and production process, the defoaming efficiency is improved, the usage cost is reduced, and energy consumption and emissions are also reduced. In addition to the basic defoaming function, future defoamers in the construction industry will also have other functions, such as improving material durability and construction performance, to meet the demand for high-quality building materials in the construction industry.

At present, the technological research and development of environmentally friendly building industry defoamers still face many bottlenecks, such as screening of raw materials, optimization of formulas, and improvement of production processes. We need to increase investment in scientific research and technological innovation to break through technological bottlenecks. The production cost of environmentally friendly building industry defoamers is usually high. How to reduce production costs while ensuring product quality and performance is a major challenge facing the industry. Although environmentally friendly building industry defoamers have many advantages, their promotion and application still face certain difficulties due to low market acceptance and awareness. So in the future, it is necessary to increase market promotion efforts and improve consumers' awareness and acceptance of environmentally friendly defoamers.
