The use of defoamers is crucial in the construction industry. However, in order to fully utilize the role of defoamers and ensure their safety and effectiveness, certain usage precautions must be followed. When selecting defoamers, it is important to fully understand the characteristics of building materials, including their composition, structure, and use, to ensure compatibility between the selected defoamer and the material. Select appropriate defoamers according to construction requirements. For example, when constructing in harsh environments such as high temperature and high pressure, defoamers that are resistant to high temperature and high pressure should be selected.

Secondly, the dosage should be reasonably controlled. When using defoamers, the recommended dosage by the manufacturer should be followed to avoid excessive or insufficient dosage. Before actual construction, small-scale tests should be conducted to verify whether the amount of defoamer added is appropriate, and adjustments should be made based on the test results.

In addition, defoamers should be stored in a dry, cool place, away from direct sunlight and high temperatures. During the construction process, it should be ensured that the defoamer is not contaminated to avoid affecting its defoaming effect. Of course, when using defoamers, personal protective equipment such as gloves, masks, etc. should be worn to prevent harm to the human body. For used defoamer containers and waste, they should be properly disposed of in accordance with environmental protection requirements to avoid polluting the environment.

In the construction industry, there are numerous precautions to be taken when using defoamers. To ensure the safety and effectiveness of defoamers, it is necessary to follow the correct selection, addition, construction, and environmental requirements. Only in this way can the role of defoamers be fully utilized to improve construction efficiency and quality.
