Application of gas-phase white carbon black in defoamers

Gas phase white carbon black plays an important role in defoamers. Its three-dimensional network structure enables it to have a strong adsorption capacity, which can quickly break the foam and prevent the regeneration of foam.
In the defoamer formula, the dosage of gas-phase white carbon black is usually around 1%, but its effect is significant. Research has shown that selecting gas-phase white carbon black with a specific surface area of 200-380 m ²/g can achieve optimal dispersion, adsorption, and anti settling effects.
In addition, hydrophobic white carbon black performs better in high-temperature strong alkali systems, effectively preventing dissolution and extending the service life of defoamers.
