Powder defoamers effectively eliminate air bubbles, resulting in a denser internal structure for the cement mortar and significantly improving mechanical properties such as compressive and tensile strength. Taking common masonry cement mortar as an example, the addition of an appropriate amount of powder defoamer can increase 28-day compressive strength by 10%–15%, thereby greatly enhancing the load-bearing capacity of the wall. Furthermore, cement mortar formulated with powder defoamers exhibits vastly improved durability. Buildings are subject to erosion from external factors—such as rainfall, moisture, and temperature fluctuations—throughout their service life. If air bubbles are present within the mortar, moisture and harmful substances can easily penetrate the building’s interior, leading to issues like rebar corrosion and wall cracking, which shorten the building’s lifespan. By eliminating these bubbles, powder defoamers increase the mortar’s density, effectively blocking the infiltration of moisture and harmful substances; this enhances the building’s impermeability and freeze resistance, ultimately extending its service life.
Safety Information
Powder defoamers from Xuhai Technology are generally non-toxic, odorless, physiologically inert, and non-corrosive. They are not classified as hazardous materials; they are non-flammable, non-explosive, and offer a high level of safety. Products should be stored in a cool, dry, and sheltered location, and containers must be tightly sealed after use. During transport, ensure containers remain sealed and protected against moisture and rain. Certain products comply with international chemical safety regulations, such as REACH.
