The defoaming and defoaming effect of defoamers is generally proportional to the amount used, but there is also a saturation point, that is, after reaching a certain concentration, adding the amount does not extend the foam suppression time. Therefore, excessive use is a waste, and the appropriate use concentration is the key to ensure that you meet the defoaming requirements, and is the key to the most economical use of defoamers.

  The defoaming and defoaming of defoamers The antifoaming agent is gradually weakened until it disappears with the passage of time. However, the defoaming of a good defoamer is much longer than the defoamer of a poor defoamer. Therefore, it is not only the initial defoaming ability, but also the length of the defoaming time, which is necessary to evaluate the effectiveness of an antifoaming agent. The long defoaming time is the most difficult quality of the defoamer, and it is the decisive factor of the defoaming performance price ratio. Good defoamer is far more than the poor defoamer at this point.

  There is no relationship between the viscosity and the concentration of the defoamer. Defoamers with high concentrations (solids) may have very low viscosity, while high-viscosity defoamers may have low concentrations. However, it is precisely a low-viscosity, high-concentration defoamer that is a high level in the manufacturing process. Therefore, users can not simply judge the quality of the defoamer from the appearance of viscosity, otherwise it is easy to draw erroneous conclusions, thus affecting your production.

The quality of defoamers can only be judged by comparative tests that eliminate foam performance.
