1, no one defoamer is omnipotent, each of defoamer only a certain scope. So choose a good defoamers defoaming crux of the problem to solve.
2, the emulsion defoamer is thermodynamically unstable system, so when adding defoamer solution or other aqueous foam system will be the impact of chemicals.
3, antifoam defoamer and defoaming amount proportional to the general effect, but there is a saturation point, that is, to a certain concentration, then add the amount of foam inhibition time can not be extended. Therefore, the excessive use is a waste, is to ensure proper use of the concentration of antifoam required to achieve your key is the key to the most economical use of defoamer.
4, defoamer antifoaming defoaming effect is over time, gradually weakened until it disappears.But the good defoamer defoamers defoaming worse than the much longer, so the quality assessment of a defoamer antifoaming ability to not only look at the initial, but also depends on the duration of suppression foam. Defoamers defoaming a long time is the most difficult to achieve quality, cost performance is a determinant of anti-foaming, good defoamer is at this point far more than poor defoamer.
5, the defoamer is no relationship between viscosity and concentration. High concentration (solid content) of the defoamer may be low viscosity, while the concentration of high viscosity of the defoamer may be very low. But it is precisely low viscosity, high concentration of defoamer in the manufacturing process is a high level. So the user can not be judged purely from the appearance of the viscosity of the defoamer is good or bad, or easy to draw the wrong conclusions, which could affect your production.
6, different manufacturers of different kinds of comparison between the concentration of defoamer is meaningless. High concentration (solid content) of the defoamer may be poorly suppression foam, but the low concentration of defoamer consumption may have a very excellent defoaming performance.
7, the defoamer is good or bad, only through the elimination suppression foam to judge the performance comparison test.
8, despite a variety of testing methods and rich foaming experience, but still clear bubbling liquid causes blistering detail, temperature, PH value and other relevant information and requirements for foaming.
