What is Defoamer?

Defoamer is an agent added to the liquid to remove surface foam and helpless air. These agents are common in many foaming liquids such as cooking oil and soap. They are also common in a wide range of industrial processes ranging from oil refinement to wastewater treatment. In most cases, the deformator is placed in a mixture of water or oil before placing in the liquid. These mixtures help to distribute the defoamer evenly through liquid and often support a specific type of air removal.

The foam is a layer of bubbles that rises to the upper part of the liquid. Regardless of the liquid, bubbles work in the same way. The air is caught in the liquid and slowly combines and creates a bubble. The bubble rises to the surface where it will collect in a thick layer of bubble or foam. It is possible that the foam would be immersed in the bottom if the liquid was somehow lighter than the air. For example, if the detergent determinent has the same foaming capacityITU like normal soap dishes, foams would quickly overflow with dishwasher. In addition, the rinsing effect of the dishwasher would not be sufficient to remove the soap residues.

These substances use a defoamer to maintain foam at a reasonable level. They do this by releasing the air trapped in the liquid and weakening the surface tension of existing bubbles to make it easier. In general, water -based defoons are better when removing the captured air and in oil they work better on the actual removal of foam. The third type of defoamer, based on silicon, has specific properties that mimic water and oils that allow it to work efficiently on naughty liquids such as oil.

oil -based defoamer is generally insoluble in foam liquid. This means that it remains in a thin layer on the upper part of the fraudster where it comes into contact with potential foam bubbles. To make the foam formed on the surface of liquidIny must go through the defoamer intact. The oil layer prevents this and allows air leakage when leaving the bubble material in the liquid.

Water -based defoons are usually soluble in liquid. These agents mix directly with the material and help collect the captured air. This air rises to the surface surrounded by a defoamer rather than on the parental fluid. When the bubble reaches the surface, the defoamer easily appears and the air is released.
