Confirm the type and dosage of defoamer before construction, and accurately weigh it according to the construction formula. Check whether the construction equipment is clean and oil-free to avoid contaminating defoamers. Ensure that the environmental conditions such as temperature and humidity at the construction site meet the

construction requirements.

When mixing materials, gradually add defoamers in the predetermined order to ensure thorough and even mixing with the material. Pay attention to observing the bubbles during the mixing process, and adjust the amount of defoamer appropriately if necessary. During the material transportation and pouring process, maintain a uniform

construction speed to avoid the generation of excessive bubbles.

After the construction is completed, clean up the construction equipment and site in a timely manner to avoid pollution caused by residual defoamers. Conduct quality inspection on the finished construction products to ensure that there are no defects such as bubbles.
