Water-based mineral oil defoamer: a powerful assistant for industrial defoaming
In industrial production and processing, the generation of foam is a common problem that needs
to be solved. As a defoamer specially designed for oily systems, water-based mineral oil
defoamers have been widely used in many industrial fields due to their high efficiency and long-lasting
defoaming performance.
1. Basic concept
Water-based mineral oil defoamer is a defoamer based on mineral oil components. Through special process
treatment, it can effectively eliminate and suppress foam in water-based or
oily systems. Mineral oil, as the main component, has good stability and chemical inertness, and can maintain
the defoaming effect under various environments. At the same time, after
special process treatment, water-based mineral oil defoamers can quickly penetrate into the foam, destroy the
stability of the foam, and thus achieve rapid defoaming.
2. Working principle
The working principle of water-based mineral oil defoamers mainly depends on their unique chemical structure
and physical properties. When the defoamer is added to the foam, it
quickly spreads to the surface and inside of the foam. Because mineral oil has low compatibility with water and
surfactants in the foam, it can form a thin oil film on the surface of the foam.
This oil film will block the gas channel in the foam, causing the foam to gradually lose stability and burst. At the
same time, the surfactant in the defoamer can also interact with the surfactant
in the foam to further reduce the stability of the foam, thereby achieving a lasting anti-foaming effect.
3. Application fields
The application field of water-based mineral oil defoamers is very wide, covering almost all industrial production
processes that need to solve the foam problem.
The following are some of the main application areas:
Oil-based coatings: In the production and construction of coatings, eliminate and suppress foam, and improve the
gloss and adhesion of coatings.
Lubricating oil: In the production and storage of lubricating oils such as diesel and engine oil, eliminate foam in oil
products to ensure the quality and use effect of oil products.
Coating: In the preparation and application of ACE coatings, eliminate foam on the surface of the coating and improve
the flatness and aesthetics of the coating.
Printing ink: In the production and printing of inks, eliminate foam in inks to ensure printing quality and stability.
Resins and building materials: In the process of resin synthesis and building materials production, eliminate and suppress
foam to ensure product quality and performance.
Textile, glue, adhesive: In the textile, glue, adhesive and other industries, eliminate and suppress foam during production and use.
Metalworking fluid: In the metal processing process, eliminate the foam in cutting fluid, coolant, etc., improve processing
efficiency and product quality.
Oil extraction: In the oil extraction process, eliminate the foam in drilling fluid, fracturing fluid, etc., to ensure the smooth
progress of the extraction process.
In addition, water-based mineral oil defoamers also play an important role in papermaking, food processing, pharmaceuticals
and other fields.
4. Usage method
When using water-based mineral oil defoamers, you need to pay attention to the following points:
Stir evenly: Before use, ensure that the water-based mineral oil defoamer is fully stirred to avoid stratification.
Direct addition: Add an appropriate amount of water-based mineral oil defoamer directly to the system that needs to be defoamed.
The generally recommended usage is 0.01%~0.03%
of the total amount, and the specific amount can be adjusted according to the actual situation.
High-speed stirring: After adding, stir at high speed to evenly disperse the defoamer in the system to improve the defoaming effect.
5. Environmental protection requirements
With the improvement of environmental awareness, modern water-based mineral oil defoamers pay more and more attention to
environmental performance. Many manufacturers
have begun to use non-toxic and harmless raw materials and strictly control the emission of pollutants in the production process.
Therefore, when selecting and using water-based mineral
oil defoamers, attention should be paid to their environmental performance to ensure compliance with local environmental
regulations and standards.
6. Conclusion
Water-based mineral oil defoamers play an important role in many industrial fields with their efficient defoaming performance and
wide application areas. During use, attention should
be paid to the use method and storage conditions to ensure its best effect. At the same time, with the continuous advancement of
technology and the improvement of environmental
protection requirements, the performance of water-based mineral oil defoamers will continue to be optimized, providing more
efficient and environmentally friendly solutions for industrial
production and processing.
