Mechanism of Defoamer for Metal Cutting Fluid -- 2021-01-15

Generally speaking, pure water and pure surfactants do not blister because their surface and interior are uniform, so it is difficult to form an elastic film. Even if they are formed, they are unstable and disappear instantaneously. However, in the presence of surfactant in the solution, the hydrophilic and hydrophobic groups in the molecules are adsorbed by the bubble wall due to the intermolecular force, forming a regular arrangement. The hydrophilic group is toward the water phase, and the hy ...
