Some common misunderstandings about defoamers
Recently, I heard that when customers compared products, they said that other defoamers can remove foam quickly and the usage is very economical. There are many misunderstandings that many people ignore. The following defoamer manufacturers introduce to you:
The defoaming and defoaming effect of defoamers is generally proportional to the usage, but there is also a saturation point, that is, after reaching the required concentration, adding more usage does not increase the defoaming time. Therefore, excessive use is a waste. The appropriate usage concentration is the key to ensure that you meet your defoaming and defoaming requirements, and it is also the key to the most economical use of defoamers.
The defoaming and defoaming effect of defoamers changes with time, gradually weakening until it disappears. But the defoaming of good defoamers is much longer than that of poor defoamers. Therefore, the evaluation of the quality of a defoamer depends not only on the original defoaming and defoaming ability, but also on the length of the defoaming time. Long antifoaming time is the most difficult quality of defoamers to ensure, and it is the decisive factor in the cost-effectiveness of antifoaming performance. Good defoamers are much better than bad defoamers in this respect.
There is no correlation between the viscosity and concentration of defoamers. High-concentration (solid content) defoamers may have very low viscosity, while high-viscosity defoamers may have very low concentrations. But it is precisely the low-viscosity and high-concentration defoamers that have the same quality in the production process. Therefore, customers cannot simply judge the quality of defoamers from the appearance viscosity, otherwise it is easy to calculate the wrong basis, which will affect your production.
The quality of defoamers can only be judged by comparative testing of antifoaming properties.
