Description
An additive used to prevent or reduce gas bubbles in a liquid system. Defoaming agents are often used in the papermaking operations since the Kraft process is particularly susceptible to foamy pulp. Many types of chemicals, such as liquid surfactants as well as solid particles, help reduce surface tension and thus rupture bubbles. Examples of defoaming agents are 2-octanol, Oleic acid, paraffinic waxes, amide waxes, sulfonated oils, organic phosphates, silicone oils, mineral oils, and dimethylpolysiloxane.
Synonyms and Related Terms
