Bubbles are a common phenomenon in our lives, but bubbles form when a large number of bubbles accumulate and are continuously distributed in a liquid. A large number of bubbles exist in life and production, which not only affects the normal work, but also causes certain pollution to the environment, so eliminating bubbles is a very necessary work.Under normal circumstances, in order to quickly realize defoaming, most enterprises will add defoaming agent for defoaming, but there are many kinds of defoaming agent, so I take silicone defoaming agent as an example to introduce the defoaming process and principle of silicone defoaming agent.How does silicone defoaming agent realize defoaming process? What's the principle?Add organic silicon defoamer to the foaming system, can quickly spread among them, the surfactant molecules in the air bubbles on the surface of the directional arrangement, when the organic silicon defoamer reaches a certain concentration, surfactant molecules enough time, can form a film in the bubble wall, and reduce the surface tension, thereby increasing the gas-liquid contact area and eventually make hard to merge and formation of air bubbles burst.Because the bubble film exposed in the air has a bimolecular membrane structure, to eliminate the foam, it is necessary to destroy and inhibit the formation of the film between gas and liquid, so the added silicone defoamer must be able to spread quickly on the surface of the solution, enter the bimolecular directional film of the foam, destroy the mechanical balance of the film, so as to achieve the purpose of defoamer.For general organic compounds, their spreading coefficient is very small, and their chemical properties are inert, so pure silicone oil cannot be used as defoaming agent, but after emulsifying it to form silicone defoaming agent, it can spread quickly on the solution surface, and use less amount to achieve many good defoaming effect.
