Foam Formation and Defoaming Solutions

Foam forms when gas is dispersed and stabilized in a liquid. The resulting mass of bubbles can quickly grow unless treated. Silicone antifoams can rapidly reduce existing foam by bridging strong foam films and breaking them. The low surface tension of defoamer droplets allows silicone to continuously penetrate adjacent foam films and break them repeatedly, increasing the intervals between antifoam applications.

Common Foam Formation Processes

Foam typically occurs during the following processes:

• Mixing
• Distillation
• Fermentation
• Filtration
• Filling

While mechanical processes can control foam, the use of chemical agents is often more versatile, effective, and economical.

The Value of Silicone Antifoam

Silicone defoamers are valuable due to their stability, compatibility with various materials, and effectiveness at low concentrations. However, it is essential to ensure their compliance with regulatory standards and suitability for specific applications to avoid any negative impact on product quality or the environment.

What is a Defoamer?

Defoamers are chemical agents designed, as the name implies, to control foam formation. These products are available in two types: silicone and non-silicone.

Excessive foam formation in industrial processes and operations can cause serious problems. These issues include surface coating defects, reduced production line efficiency, and even bacterial growth. Additionally, foam overflow can pose slip hazards and increase the time and cost of cleaning. Therefore, the benefits of using defoamers include improved productivity, enhanced production output, and even increased safety.

Difference Between Defoamer and Foam Suppressant

The terms defoamer and foam suppressant are sometimes used interchangeably, but they have important differences:

• Defoamers are designed to prevent foam formation and are added at the start of the process.
• Foam suppressants are used to eliminate existing foam and are applied as needed.

Why Ultrachem Silicone Defoamer from Bonyan Shimi Hamgam Sanat?

The defoamer market is dominated by silicone products. These are preferred due to the following advantages:

• Low surface tension
• Chemical inertness
• Thermal stability
• Completely insoluble in water

Silicone defoamers are usually polymers with a silicone backbone and are available in oil-based or aqueous forms. These products spread rapidly over foam surfaces due to their low surface tension and cause foam bubbles to burst.

Structure of Silicone Defoamer:

The main composition of silicone defoamers includes hydrophobic silica dispersed in a silicone oil. Emulsifiers are added to enhance speed and uniformity of dispersion.

Silicone antifoams are highly effective at breaking surface foam and releasing trapped air. Some of these products are also suitable for non-aqueous systems like crude oil and oil refining.

Non-Silicone (or Organic) Defoamers

Defoamers are also available in other forms like mineral and organic products.
Due to the high efficiency of silicone products, the use of non-silicone defoamers has declined in some applications. However, these are still used in wastewater treatment and process water applications where silicone products are not permitted.

These organic defoamers usually require higher dosages for effectiveness, increasing costs and often making silicone solutions more desirable.
