Defoamers, a specialized type of functional additive, play an indispensable role in industrial production by destabilizing foam or inhibiting its formation.

The application of defoamers is particularly critical in the petrochemical industry. 

Foam generated during the refining process can cause distillation tower flooding, seriously impacting production efficiency. Defoamers can maintain stable performance in high-temperature (above 150°C) and strong acid and alkaline environments (pH 2-12), increasing the processing capacity of catalytic cracking units by 20%.

 

The papermaking industry is a traditional application area for defoamers. During the pulping and papermaking processes, materials such as fibers and resins easily form stable foam, which affects product quality and production efficiency. Defoamers, through composite silicone and polyether modification technology, can reduce the foam half-life of black liquor from 5 minutes to less than 30 seconds.

The food processing industry has special requirements for defoamers. In fermentation processes, foam generated by microbial metabolism can reduce the effective volume of fermentation tanks and even cause overflow accidents. During the fermentation process of soy sauce, beer, and other products, adding 0.01-0.05% can control foam height without affecting microbial activity or product flavor. Specifically, in monosodium glutamate production, specialized defoamers can increase the fermentation tank filling factor from 70% to 85%, significantly improving equipment utilization.

Defoamers are increasingly used in water treatment. Foam generated during wastewater aeration can cover the tank surface, hindering oxygen transfer and observation. Our defoamer series offers the dual functions of rapid foam breakdown (<10 seconds) and long-lasting foam suppression (>8 hours), increasing oxygen utilization in aeration tanks by 25%.

The coatings and inks industry places specific demands on defoamers. Foam can cause defects such as pinholes and fisheyes in paint films, impacting product appearance and performance. Our defoamer series, through molecular structure design, achieves a balance between defoaming performance and coating compatibility. Experimental data shows that adding 0.1-0.3% defoamer can reduce surface defects in water-based coatings by over 95% without affecting the film's gloss or adhesion.

The pharmaceutical industry has extremely stringent requirements for defoamers. In processes such as antibiotic fermentation and vaccine production, defoamers must be both highly effective and biosafe. Our defoamer products are certified to USP, EP, and other pharmacopoeia standards. Cytotoxicity testing has shown that their impact on CHO cell viability is less than 5%.

Textile printing and dyeing is another important application area for defoamers. Foaming during high-temperature dyeing can cause color fringing and color shift. Our defoamer products are temperature-resistant up to 130°C and maintain excellent performance even in strong alkaline conditions (pH 14).
