Currently, with the rapid development of the construction industry, the market for cement mortar defoamers is also showing a thriving trend. There are numerous brands and a wide variety of products in the market, ranging from organosilicon, polyether to mineral oils, each with its own characteristics. Meanwhile, with the increasing awareness

of environmental protection, environmentally friendly defoamers are gradually gaining favor in the market.

Understand the requirements, clarify the construction environment, cement mortar formula, and quality requirements, and select the appropriate type of defoamer. Pay attention to quality, choose well-known brands, and focus on product purity, stability, and environmental performance. Cost effectiveness, while ensuring effectiveness, should

be considered to avoid blindly pursuing low prices. Trial verification: Conduct a small-scale trial before formal construction to verify the defoaming effect and compatibility with cement mortar.
