Performance characteristics: high efficiency, can quickly eliminate foam, reduce foam residue. Stability, able to maintain stable defoaming effect even in harsh construction environments. Compatibility, with good compatibility with building materials, does not affect the performance and quality of the materials. Environmentally friendly, non-

toxic and harmless, in compliance with environmental standards, and environmentally friendly. Economically, while ensuring effectiveness, the cost is relatively low.

Selection factors: Construction environment, considering the impact of factors such as temperature, humidity, and pressure on the performance of defoamers. Select appropriate defoamers based on the type, formula, and performance requirements of building materials according to their material properties. Effect evaluation, verifying the

effectiveness of defoamers through sample testing and actual construction. Environmental protection and safety, ensuring that the selected defoamer meets environmental standards and safety requirements.
