Defoamer for concrete is one of the commonly used additives in the preparation process of concrete, and its correct use and precautions are of great significance for ensuring the quality of concrete. First of all, when using the defoamer for concrete, add the defoamer to the water in a certain proportion and fully mix it evenly, then add the concrete defoamer solution to the concrete for mixing until the foam on the concrete surface is completely eliminated, and then continue to follow the normal concrete production process until the concrete is completely set.

When using defoamers for concrete, we need to pay attention to selecting the appropriate type of defoamer according to the specific situation. Different types of defoamers have different properties and uses, and should be comprehensively considered based on factors such as concrete foaming, production process, and cost. When using defoamers, the dosage should be strictly controlled. Excessive defoamers may lead to a decrease in concrete performance and even affect the quality of concrete. Therefore, sufficient testing and mixing should be conducted before use to ensure that the dosage of defoamer is appropriate. In addition, during the storage and transportation of concrete defoamers, attention should be paid to avoiding high temperatures, direct sunlight, and other situations. These factors may affect the quality of defoamers, leading to a decrease in defoaming effectiveness. Therefore, defoamers should be stored in a cool and dry place, avoiding direct sunlight and high temperature environments. When using defoamers for concrete, attention should be paid to protecting the skin and eyes. Defoamers may have a certain degree of corrosiveness or irritation. When using, attention should be paid to wearing protective gloves and goggles to avoid chemical burns. During the use of concrete defoamers, attention should be paid to strengthening ventilation and air exchange. Defoamers may produce harmful gases or vapors during use, and ventilation should be strengthened to avoid inhaling harmful gases and causing harm to health.

In summary, the correct use and precautions of defoamers for concrete are of great significance for ensuring the quality of concrete. Before use, sufficient understanding and testing should be conducted to ensure the selection of appropriate defoamer types and appropriate dosage, while paying attention to safety issues during storage, transportation, and use.
