Defoaming Agents

Defoamer should have the following properties: 1. strong defoaming power, low dosage; 2. added to the foaming system does not affect the basic properties of the system, that is, not react with the defoaming system; 3. surface tension is small; 4. and the surface of the balance of good; 5. good heat resistance; 6. diffusibility, permeability, positive spreading coefficient of high; 7. chemically stable, oxidation-resistant; 8. gas solubility, permeability; 9. in the foaming solution of the solubility, good; 9. Small solubility in foaming solution; 10. No physiological activity, high safety.

Defoaming Agent is widely used, such as food industry, paper industry, water treatment, oil industry, printing and dyeing industry, paint industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, dairy industry.

The composition of defoamer mainly consists of active ingredient, emulsifier, carrier and emulsification aids, in which the active ingredient is the most important core part, play the role of breaking foam, reduce surface tension; emulsifier is to make the active ingredient dispersed into small particles, in order to facilitate better dispersion into the oil or water, to play a better defoamer effect; carrier accounts for a larger proportion of the antifoam agent, its surface tension is not high, mainly play a role in supporting the medium The surface tension of the carrier is not high, and it mainly plays the role of supporting medium, which is beneficial to the effect of foam inhibition and defoaming, and can reduce the cost; emulsification additives are to make the emulsification effect better.
