A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam.

2024年11月29日 · Defoamers, also known as antifoaming agents, are chemical products specifically designed to reduce or eliminate foam in liquids. Foam is typically created when air or gas is trapped in a liquid, stabilized by surfactants or other compounds. This can disrupt industrial processes and even damage equipment.

Defoaming is the process of removing bubbles and air from liquids to prevent decay and oxidation. As a result, this process enhances freshness and quality, extends shelf life, maximizes production, and avoids problems in process control and equipment operation (Awad et al., 2012).

Defoamers, also known as antifoaming agents, are chemical additives used to reduce and prevent the formation of foam in industrial processes. Foam can cause problems such as decreased efficiency, product contamination, and equipment damage.

2023年7月3日 · Defoamers are chemical compounds used to remove or minimise foam in industrial operations. The Indian market for defoamers is growing, with leading producers creating premium goods. Foam formation may concern various sectors, from chemical manufacturing to food and beverage production.

2025年1月20日 · Defoaming can be achieved by adding substances (defoamers) that accelerate the drainage of the foam film. If the foam film is thick, the drainage process to 30–40 nm is long, and the self-healing effect of the foam film is strong, and the foam film is elastic, so the foam life of the thick foam film is long, and the drainage rate of the foam ...

2024年10月1日 · The extensive formation of foam might cause serious problems so special additives called defoaming agents or defoamers are used to subdue the formation of foam or eliminate the foam formed. What is a defoamer?

2024年9月5日 · A defoamer, also known as an antifoam or defoaming agent, is a chemical additive used to reduce and prevent foam formation in industrial processes and products. It works by destabilizing the foam lamellae, causing the foam bubbles to coalesce and collapse.

Defoamers, antifoaming agents, and air release agents are chemical processing aids employed to minimize or eliminate foam in industrial operations. While the terms are often used interchangeably, they employ different mechanisms, so it is worth distinguishing between them.

2020年12月1日 · Defoamers are comprised of a liquid, such as mineral oil or silicone, and a hydrophobic solid, such as hydrophobic silica, ethylene-bis-stearamide, fatty acid, and/or fatty alcohol. An effective defoamer must be insoluble in the medium it is defoaming.
