Concrete defoamer supplied by Henan Kingsun is a compound composed of polyether surfactant and dry powder material. It has the characteristics of high efficiency, low addition amount, and faster reaction speed than traditional defoamer powder. It usually completes defoaming within 30 seconds after mixing with water. It is suitable for defoaming under strong acid and alkali conditions. When the pH value of the defoaming system is 14, this series of defoaming agents can maintain a good physical state, no demulsification, no oil floating, rapid defoaming, long-lasting foam suppression, and non-toxic, odorless. Meanwhile, it will not cause any pollution to the environment. The amount of this product used for defoaming is small and the cost of use is low. Cement defoamer for sale in our company has excellent performance in reducing bubbles in the solution and is particularly suitable for cement-based materials such as grouting materials, self-leveling cement and gypsum products, and other materials with special requirements for surface appearance.

âPerformance Advantages of Polyether Concrete Defoamer
âStrong temperature responsivenessâ. The solubility of the polyether molecular chain changes significantly with temperature. It dissolves in water at low temperatures and precipitates and adsorbs on the foam surface at high temperatures to play a defoaming role. This “on-demand defoaming” feature makes it suitable for dynamic processes such as fermentation and high-temperature wastewater treatmentâ.
âHigh biodegradabilityâ. Compared with silicone defoamers, polyether defoamers are more easily degraded by microorganisms. It has a low risk of environmental residues, and meet the health and environmental standards of the food, pharmaceutical and other industries.
âCompatibility and safetyâ. Polyether defoamers are compatible with most water treatment agents, are non-toxic and non-irritating. They are suitable for food processing, pharmaceuticals and other fields with strict safety requirements. In addition, their chemical properties are stable and will not react chemically with other components in the system, ensuring the stability of the product.
âGood shear resistanceâ. It is not easy to demulsify and fail in high shear force or circulating water flow systems, and is suitable for industrial systems with frequent pumping, such as circulating cooling water.
âGood environmental protectionâ. Polyether defoamers donât contain harmful substances such as minerals, silicon, phosphorus, etc., They are environmentally friendly and easy to degrade.
âGood dispersibilityâ. Polyether defoamers have good dispersibility in water, can be quickly dissolved, do not float oil, and do not stratify.
âWide range of applicationâ. Polyether defoamers perform well in low and medium temperature systems that require high safety and degradability, such as food fermentation, pharmaceutical wastewater, and circulating cooling water.
Affect the performance and durability of concrete. Bubbles in concrete can cause the internal structure of concrete to become loose, reducing its bearing capacity. In addition, bubbles increase the water absorption of concrete, reduce its impermeability and durability, and thus affect the overall performance and service life of concrete.
Affect construction quality and appearance. During pouring and vibration, bubbles hinder the compactness of concrete, causing pores and honeycomb surfaces on the surface of concrete, affecting construction quality and appearance. Using cement defoamers can eliminate these bubbles and make the concrete surface smoother and flatter.
Improve construction efficiency. Concrete Defoamers can improve the fluidity of concrete, making it easier to construct and pour, thereby improving construction efficiency and reducing manpower and time costs.
Enhance the mechanical properties of concrete. By eliminating bubbles, defoamers can reduce the voids in concrete, improve the density and compressive strength of concrete, and thus enhance its mechanical properties.
âAdapt to a variety of construction environmentsâ. Concrete defoamers have good adaptability and dispersibility, are suitable for various types of concrete and construction environments, and can quickly eliminate bubbles in a short timeâ.
âOrganic silicon defoamersâ. This type of defoamer has the characteristics of low surface tension, high surface activity, strong defoaming ability, small dosage and low cost. However, they have poor compatibility with concrete materialsâ.
âPolyether defoamersâ. Polyether defoamers have good defoaming and anti-foaming functions and good compatibility with concrete. Although its defoaming effect is not as strong as that of organic silicon defoamers, its application effect in concrete is stableâ.
âPolyether modified silicon defoamersâ. This defoamer combines the advantages of organic silicon and polyether defoamers, with strong defoaming ability, good compatibility and less addition. However, its price is relatively highâ.
âPolycarboxylic acid defoamersâ. Mainly used for polycarboxylic acid water reducers, waterproofing agents, environmentally friendly concrete admixtures, etc. They have stable chemical properties, are not affected by the environment, and are suitable for use in low temperature areasâ.
âDefoamer powder for cement mortarâ. Mainly used for interior and exterior wall putty, gypsum prefabricated panels, plastering plaster, caulking agents and other scenes. This powdered defoamer has strong fluidity, convenient transportation, and high compatibilityâ.
- Construction industry. In the production process of building materials such as concrete, cement mortar, putty, etc., The use of cement defoamers can effectively control the generation of bubbles and improve the density and strength of the products.
- Road construction.During road construction, the use of cement defoamers can reduce bubbles in road construction and improve the smoothness and durability of the road.
- Prefabricated component production.In the production process of prefabricated components such as beams, columns, and plates, the use of cement defoamers can improve the appearance quality of the products and improve their performance.
- Other fields.Cement defoamers can also be used in water conservancy, power, ports and other projects, such as the concrete pouring process of reservoir dams, hydropower stations, docks and other projects.
