Water-based mineral oil defoamers are widely used in the manufacturing industry. Their efficient defoaming
performance and wide applicability make them a powerful assistant in many
industrial fields. The following is a detailed discussion of the application of water-based mineral oil defoamers
in the manufacturing industry:
1. Basic concepts and working principles
Water-based mineral oil defoamers are defoamers based on mineral oil components. Through special process
treatment, they can effectively eliminate and suppress foam in water-based
or oil-based systems. Its working principle mainly relies on the incompatibility between mineral oil and the
water and surfactants in the foam, thereby forming a thin oil film on the surface
of the foam, blocking the gas channel in the foam, causing the foam to gradually lose stability and break.
2. Specific applications in the manufacturing industry
Paint manufacturing
During the production and construction process of paint, water-based mineral oil defoamers can eliminate
and suppress foam, and improve the gloss and adhesion of the paint. This is
crucial to ensure the quality and construction effect of the paint.
Lubricant manufacturing
During the production and storage of lubricants such as diesel and engine oil, water-based mineral oil
defoamers can eliminate foam in oil products and ensure the quality and use effect of
oil products. This is of great significance for extending the service life of equipment and improving work efficiency.
Metal processing
During the metal processing process, cutting fluids, coolants, etc. are prone to foaming. Water-based mineral oil
defoamers can quickly eliminate these foams and improve processing
efficiency and product quality.
Printing inks
During the production and printing of inks, water-based mineral oil defoamers can eliminate the foam in the ink to
ensure the quality and stability of printing. This is crucial to improving
the quality of printed products.
Building materials manufacturing
During the resin synthesis and building materials production process, water-based mineral oil defoamers can eliminate
and suppress foam to ensure the quality and performance of products.
This is of great significance for improving the durability and use effect of building materials.
Textiles, glues, adhesives
In the textile, glue, adhesive and other industries, water-based mineral oil defoamers can eliminate and suppress foams
during production and use, and improve product quality and stability.
Oil extraction
During the oil extraction process, drilling fluids, fracturing fluids, etc. are prone to foaming. Water-based mineral oil
defoamers can eliminate these foams to ensure the smooth progress of
the extraction process.
3. Precautions for use
Stir evenly: Before use, ensure that the water-based mineral oil defoamer is fully stirred to avoid stratification.
Add appropriate amount: According to actual needs, 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, but the specific amount should be adjusted according to
actual conditions.
High-speed stirring: After adding, high-speed stirring should be performed to make the defoamer evenly dispersed in the
system to improve the defoaming effect.
4. Advantages and limitations
Advantages:
Efficient defoaming: It can quickly penetrate into the foam and destroy the stability of the foam, thereby achieving
rapid defoaming.
Persistent anti-foaming: While eliminating foam, it can also form a protective film in the system to inhibit the
regeneration of foam.
Good chemical stability: It can maintain its defoaming performance in a variety of acid and alkali environments.
High temperature resistance: It can still play a good defoaming effect under high temperature conditions.
Limitations:
Poor compatibility: The defoaming effect on intensive foam may be average, and it is not very suitable for high shear
force environments.
Color impact: not suitable for products with strict color requirements.
In summary, water-based mineral oil defoamers have broad application prospects and important value in the manufacturing industry.
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 the manufacturing industry.
