With the increasing global awareness of environmental protection and the increasingly strict environmental regulations, the environmental performance of defoamers in the metal processing industry has become a focus of industry attention. Governments around the world have introduced relevant policies to restrict or prohibit the use of high VOC (volatile organic compounds), difficult to degrade, or harmful substances, promoting the industry's transition towards green and sustainable development. As a major energy consumer and pollutant emitter, the metal processing industry has an increasingly urgent demand for environmentally friendly defoamers.

Under the promotion of environmental policies, the research and development of green metal processing defoamers is of great significance. Firstly, it helps companies comply with environmental regulations, avoid legal risks and fines; Secondly, green defoamers can reduce environmental pollution and lower the ecological footprint during the production process; Furthermore, green products often better meet market demand and help enhance corporate image and product competitiveness. Therefore, developing efficient, environmentally friendly, and economical defoamers for the metal processing industry is an important measure to promote the sustainable development of the industry.

In order to meet environmental protection needs, the research and development of defoamers in the metal processing industry is gradually expanding into the fields of new materials and new technologies. On the one hand, researchers are committed to developing defoamers based on renewable resources or biobased materials, such as plant oil-based and starch based, to reduce dependence on petroleum resources and environmental pollution; On the other hand, by applying advanced technologies such as nanotechnology and microencapsulation, the stability and durability of defoamers can be improved, while reducing their usage and minimizing environmental impact.

The performance evaluation of green metal processing defoamers not only focuses on basic indicators such as defoaming efficiency and foam suppression durability, but also needs to focus on their environmental performance. The assessment includes but is not limited to VOC emissions, biodegradability, heavy metal content, and impact on ecosystems. By using scientific testing methods and standard systems, we ensure that green defoamers not only have excellent defoaming performance, but also meet the requirements of environmental regulations.

Market promotion is the key to the success of green metal processing defoamers. Enterprises need to promote the advantages and characteristics of green defoamers through various channels such as exhibitions, technical exchange meetings, and online marketing, in order to increase user awareness and acceptance. At the same time, strengthen cooperation with downstream enterprises, jointly promote the construction of green supply chains, and achieve win-win development of the upstream and downstream of the industrial chain. In addition, by providing high-quality after-sales service and technical support, we aim to enhance users' confidence and satisfaction with green defoamers.

With the continuous strengthening of environmental policies and technological progress, green metal processing industry defoamers will usher in a broader development prospect. In the future, defoamers in the metal processing industry will pay more attention to the development of environmental performance, economy, and intelligence to meet the constantly changing market demands. Meanwhile, with the continuous emergence of new materials and technologies and the expansion of application fields, the performance of green defoamers will continue to improve, providing stronger support for the sustainable development of the metal processing industry. In this process, enterprises need to maintain keen market insight and innovation capabilities, constantly promote product and technology upgrades and iterations, in order to occupy a favorable position in the fierce market competition.
