Significant progress has been made in the environmental friendliness of defoamers in the construction industry, mainly reflected in the following aspects:

1、 The greenization of raw materials has led to an increasing use of environmentally friendly materials in modern construction industry defoamers, which typically have low toxicity, low volatility, and biodegradability. Some new defoamers use natural plant extracts, environmentally friendly surfactants, inorganic defoamers, and other active ingredients as active ingredients. These ingredients not only effectively defoam, but also reduce environmental pollution.

Traditional defoamers may contain harmful substances such as heavy metals and volatile organic compounds, which may cause environmental pollution during use. Modern environmentally friendly defoamers strictly control the content of these harmful substances to ensure that the product does not cause harm to the environment during use.

2、 The environmental friendliness of the production process, as well as the increasing emphasis on clean production in the production of defoamers in modern construction industry, aims to reduce environmental pollution during the production process by optimizing production processes, improving production efficiency, and reducing waste emissions. Some enterprises also adopt advanced wastewater treatment equipment to purify the wastewater generated during the production process, ensuring that the wastewater meets the discharge standards. In the production process of modern defoamers, more and more energy-saving technologies are being adopted. At the same time, enterprises are improving production processes, increasing raw material utilization, reducing waste generation, and further reducing environmental pollution.

3、 The environmental performance of products, modern environmentally friendly defoamers usually have good biodegradability, which means they can be decomposed by microorganisms during use and will not cause long-term pollution to the environment. Traditional defoamers may release volatile organic compounds during use, which are harmful to the environment and human health. Modern environmentally friendly defoamers strictly control the emission of volatile organic compounds to ensure that the product does not cause pollution to the environment during use.

4、 Adhering to environmental regulations, modern construction industry defoamers strictly comply with national and local environmental regulations and standards in the research and production process, ensuring that products meet relevant requirements. More and more defoamer products in the construction industry have obtained environmental certification, which proves the excellent performance of products in environmental protection and the environmental responsibility of enterprises.

I believe these developments will drive the defoamer industry in the construction industry towards a more environmentally friendly and sustainable direction.
