Defoamers need to have characteristics such as rapid defoaming, long-term foam suppression, no impact on the performance of processing media (such as lubricity and cooling effect), no residue, and easy cleaning. The correct selection and application of defoamers are crucial for improving production efficiency and reducing costs. When selecting, factors such as the properties of the processing medium (such as water-based, oil-based), processing temperature, pH value, stirring intensity, and special requirements for environmental protection and safety of the product should be considered.

Moderate addition, too much or too little addition can affect the defoaming effect, and the optimal addition amount needs to be determined based on experiments. Uniform dispersion ensures that the defoamer is evenly dispersed in the processing medium, which can be achieved through pre mixing or stirring equipment. Regularly inspect and check the foam condition, and replenish defoamer as needed. Pay attention to compatibility and avoid adverse reactions with other components in the processing medium.
