Core Functions and Industrial Applications of Cement Mortar Defoaming Powder

Cement mortar defoaming powder, as a vital additive in industrial multiphase systems, rapidly eliminates foam and inhibits its regeneration, ensuring the compactness and mechanical properties of concrete structures. Chemi Tech leverages molecular structure design and process innovation to develop high-performance defoaming solutions for complex construction scenarios.

In concrete production, factors like improper aggregate gradation or high water-cement ratios may cause foam accumulation, leading to surface defects and reduced compressive strength. Chemi Tech's defoaming powder reduces liquid surface tension and disrupts foam film elasticity, functioning stably in highly acidic or alkaline environments without issues like demulsification. For instance, in tunnel shotcrete applications, adding defoaming powder reduces rebound rates to 3.2%, significantly improving material utilization and minimizing dust pollution.

Chemi Tech's innovation lies in composite functional design. By optimizing polyether-modified siloxane molecular chains, its products maintain long-term activity under high temperatures (<75°C) or shear conditions. Tests show that adding 0.1%~0.3% defoaming powder reduces air content by 40% while enhancing fluidity and bonding strength. Rheological analysis confirms its ability to adapt to varying mixing speeds, preventing performance degradation due to process fluctuations.

Future initiatives include AI-driven optimization of HLB values and particle distribution, expanding applications in self-leveling cement and waterproof mortars to deliver customized industrial solutions.
