Defoamers, as important additives in industrial production and food processing, can effectively control the production of foam and improve the stability of products. However, in practical use, improper operation or neglect of key details can easily lead to poor defoaming effect, product deterioration, and even safety hazards.

For example, insufficient stirring of defoamers during use can lead to delamination, incomplete dissolution or dispersion of defoamers, and the formation of local aggregates in the solution, resulting in uneven defoaming effects and even secondary foaming. Therefore, we need to shake or stir the defoamers thoroughly before use to ensure uniform composition.

Secondly, improper dosage of defoamers can easily lead to differences in effectiveness. Excessive addition may cause a decrease in product viscosity, while insufficient dosage may result in incomplete defoaming, affecting product appearance and stability. Therefore, we can determine the optimal dosage through small-scale experiments. For example, in coating production, a gradient test can be conducted at a ratio of 0.1% -0.5% to observe the defoaming speed and system stability. At the same time, the dosage can also be dynamically adjusted according to the stage of foam production. For example, in the fermentation industry, a small amount can be added at the initial stage to prevent foaming, and then added when the foam surges at the later stage.

Our common problem is improper storage after dilution. Some defoamers need to be diluted before use, but if the diluent is stored for a long time, it is prone to failure due to microbial growth or component separation. So we need to prepare and use it immediately. It is recommended to use the diluted defoamer within 24 hours and avoid storage. If short-term storage is needed, it should be stored in a sealed environment at low temperature to prevent water evaporation or impurities from entering.

Therefore, defoamers should strictly follow the conditions of sufficient mixing, reasonable dosage, and on-site preparation and use during use, effectively balancing operational norms and avoiding human errors as much as possible. Enterprises can regularly carry out activities such as training operators on safety awareness to strengthen safety awareness and emergency response capabilities. Through scientific management and detailed optimization, the application effect of defoamers can be significantly improved, ensuring product quality and production safety.
