Cement mortar defoamer is a type of chemical additive specifically designed to control and eliminate bubbles generated during the mixing and construction process of cement mortar. Defoamer molecules can quickly penetrate and adsorb onto the surface of bubbles, reducing their surface tension and making the bubble walls fragile and

prone to rupture. Part of the defoamer components can inhibit the elastic recovery of the bubble film and prevent the formation of bubbles again. Defoamers can also promote the rapid discharge of liquid inside bubbles, further accelerating the bursting of bubbles.

Cement mortar defoamers are widely used in concrete and mortar construction in engineering fields such as construction, roads, bridges, tunnels, etc., to ensure construction quality and structural safety.
