What are the functions of defoamers?

There are many types of it; at the very least, this particularly crucial variety boasts a wealth of properties, making it an outstanding defoaming agent. First and foremost, it is a completely non‑toxic liquid, so you can use it without worrying about adverse health effects. Moreover, it has no distinct odor, ensuring a pleasant sensory experience, and it is entirely non‑toxic, causing no discomfort whatsoever.

Why is a defoamer called “industrial MSG”?

Why is it called “industrial MSG”? As a flavor‑enhancing chemical, MSG has become ubiquitous in our diets and daily lives. In fact, industrial production also employs a substance very similar to chicken bouillon; used in small quantities, it delivers remarkable results—this is the defoamer.

Common Issues and Functions in the Use of Defoamers

In industrial production, certain regions that manufacture foam plastics often use defoamers to eliminate the foaming that occurs during processing. Throughout the application of defoamers, numerous challenges may arise; today, we’ll discuss several common issues and their solutions.

Is an antifoaming agent flammable?

Today, industrial‑grade defoamers are predominantly used in industries such as food processing, architectural coatings, and petrochemical equipment manufacturing. The types of defoamers employed vary significantly across different sectors. Because defoamers are typically liquid and packaged in bottles, many people assume they are hazardous materials. In this article, we will examine whether defoamers truly qualify as hazardous substances.

What are the characteristics of silicone-based water treatment defoamers and oil-based defoamers?

Generally speaking, pure water and pure surfactants do not form bubbles because their surfaces and interiors are uniform, preventing the formation of a flexible, elastic film; even if such a film does form, it is unstable and quickly collapses. However, when a surfactant is present in the solution, upon bubble formation, intermolecular forces cause the hydrophobic and hydrophilic groups within the surfactant molecules to adsorb onto the bubble wall, arranging themselves in a specific orientation: the hydrophobic groups face the aqueous phase, while the hydrophilic groups point toward the interior of the bubble. This results in the creation of an elastic membrane at the bubble’s surface, which is highly stable and resistant to rupture under normal conditions.

The Mechanism of Action of Foaming and Defoaming Agents

When a liquid is stirred or gas is introduced into it, numerous bubbles form throughout the liquid’s volume. In some liquids, these bubbles rapidly collapse and disappear; in others, they not only persist but also accumulate, giving rise to foam. Foam is a dispersed system in which a large number of gas bubbles are evenly distributed within a liquid, with gas as the dispersed phase and liquid as the continuous phase. Although the gas occupies only a small fraction of the total volume, the resulting foam occupies a substantial space. The gas is separated by thin liquid films, forming bubbles of varying sizes that collectively constitute the foam.
