Polyether defoamer is a kind of additive that can defoamer in concrete. Its mechanism of action is to change the surface tension and viscosity of the bubbles in the concrete, so that the bubbles can be more easily separated from the concrete. The molecular structure of polyether defoamer contains a large number of hydroxyl groups and polyether chains, which makes it have good dispersion and stability. After the polyether defoamer is added to the concrete, it can interact with the water molecules in the concrete to form a stable bubble film, thereby preventing the fusion and diffusion of bubbles and achieving the effect of defoaming. The use of polyether defoamer is relatively simple. Generally speaking, polyether defoamer can be added directly to the cement slurry of concrete for mixing. In the process of mixing, the polyether defoamer can be evenly dispersed in the concrete and interact with the bubbles. In order to achieve the best defoaming effect, it is necessary to determine the amount of polyether defoaming agent added according to the ratio of concrete and the use requirements. Generally speaking, the amount of polyether defoamer is 0.1% to 0.3% of the total amount of concrete, and the specific amount can be adjusted according to the actual situation.
