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.

2023年7月3日 · Defoamers are chemical compounds extensively used in industrial operations to remove or minimise foam. These substances are also called "anti-foaming agents". They are usually injected directly into the foam-forming liquid or gas, destabilising the foam and stopping it from developing.

2022年2月2日 · What Are the different types of anti foaming agents and what are they used for? Popular perceptions of anti foaming agents and defoamers are said to include four primary types of anti foaming and defoaming agents.

2022年4月21日 · The key difference between defoamer and anti-foam is that anti-foam agents can prevent foam from forming, whereas defoamers can control the amount of existing foam. Therefore, anti-foam agents prevent foam formation while defoamers reduce existing foam.

Antifoaming agents have high surface activity that can lower the surface tension of local film when its micro droplet contacts liquid film. This local area of low surface tension will extend all around, losing elasticity and self-restoring ability, thus causing the rupture of liquid film.

2020年1月21日 · Let’s introduce antifoams, a group of chemical agents available in two types — silicone and non silicone-based (or organic). What are their specific uses and which one do I need? What exactly are these functional, versatile products and how do they work?

Antifoaming agents are added to prevent or counter the foam generation in the formulation. Generally, these agents have surface active properties and are insoluble in the foaming medium.

2022年5月9日 · Antifoaming agents work to avert the many detrimental effects of foam before it becomes a problem. Proper selection and application saves time and money, keeping processes running smoothly and maintaining consistent product quality.

2024年5月25日 · Anti-foaming agents, also known as defoamers, are chemicals added to liquids to reduce and hinder the formation of foam. Foam formation is a common issue in various industrial processes, and if not controlled, it can drastically affect process efficiency, product quality, and system stability.
