Have foam formation problems? Looking for an antifoaming agent?
Foam is formed from contaminants such as proteins and small solid particles. Therefore, foam contributes to problems in the fluid system and many more locations if not taken care of properly. Hence, to prevent this problem, you need to use an antifoaming agent or defoamer.
Antifoaming agents or defoamers are quite similar, however, the contrast only applies to their timing of application. Antifoaming agents are used to preventing the formation of foam. Defoamers, however, eliminate existing foam.
Antifoaming agents are comprised of mineral oil, hydrophobic oil, silicone, and a hydrophobic solid. A good antifoaming agent is insoluble, otherwise, it’s not a good one.
In industrial processes, the control of foam formation is important. Foam can cause so many issues such as defective products. Hence, antifoaming agents are used. You need to look for the right antifoaming agent Selangor Malaysia company.
Where to apply antifoaming agents?
Antifoaming agents are added into processes and the products themselves to avoid foam formation. The formation of foam could result in hindrances. For example, dishwasher agents should have low foam for the dishwasher to work efficiently.
Additionally, in food ingredients, agents are added to control fizziness in the preparation process and the point of serving.
Due to the process, the organic materials release foam, and this could be a problem. Hence, applications include:
- Grain separation
- Washing and processing of fruits and vegetables
- Processing of meat and poultry
- Dairy products
Antifoaming agents in water treatments prevent air and waterborne foam from appearing. Hence, applications include:
- Boiler water treatment
- Cooling towers
- Evaporation water treatment
- Manure pits
Paint, inks, coatings, and adhesive (PICA)
Foam is prone to appearing during the rigorous mixing of the chemicals. Therefore, foam that is not managed will lead to more time wasted, less efficiency, and product defects. The anti-foaming agent is used in:
- Pigment grinding
- Package filling
Cleaning compounds and processes
In the production as well as the product itself, foam control products are applied. Hence, applications include:
- Laundry detergents
- Carpet cleaners
- Personal care items
- Soap and detergents
Types of anti-foaming agents
Oil-based antifoaming agents use an oil carrier. For example, mineral oil, white oil, and vegetable oil. This type of antifoaming agent is powerful and is the best at destroying any foam’s surfaces.
Similar to oil-based antifoaming agents, but carries particulate carriers such as silica. This type of antifoaming agent is added to powdered products. For example, plaster, cement, and detergents.
This type of oil-based antifoaming agent includes oil; such as mineral oil or vegetable oil. These materials are the best at releasing entrained air.
This type of agent uses polymers with silicones backbones mixed in oil or water-based compounds. This type of antifoaming agent is appropriate for non-aqueous foaming systems such as oil refining. The food industry uses this type of agent in food preparation, water treatment, and so on.
