AI Overview
High-efficiency antifoam agents for calcium silicate boards are typically hydroxyl-based compounds, such as AF-502 or AF-801, or specialized silicone emulsions that offer fast defoaming, excellent dispersion, and long-lasting foam suppression in high-temperature and high-shear production environments. These additives ensure smooth, durable, and dense boards.
Recommended Antifoam Types & Specific Products:
- Hydroxyl/Polyether Compounds (e.g., AF-502, AF-801, AF-060): Known for being easy to disperse and providing both fast defoaming and long-lasting suppression in fiber cement and calcium silicate systems.
- Specialized Defoamer AS-01: Specifically designed for calcium silicate board production, offering high-temperature resistance and compatibility within the mix.
- Fatty Acid Esters (e.g., AF-601, AF-712): Suitable for applications requiring low viscosity and reliable foam control.
- Silicone Emulsions (e.g., XIAMETER AFE-0010): Effective for managing aqueous foam in high-shear production lines, offering high potency at low dosages.
Key Performance Benefits:
- Fast Breaking & Inhibition: Rapidly eliminates existing foam and prevents new foam formation.
- High-Shear Resistance: Maintains structural integrity under high-speed mixing and pumping.
- Excellent Compatibility: Does not negatively impact the binding or curing process of the calcium silicate board.
For industrial-scale applications, specialized cement defoamers from manufacturers like AEOR Chemical are often used to improve the surface finish and structural integrity of the boards.

What is the main ingredient in defoamer?
Silicone-based defoamers
The silicone compound consists of a hydrophobic silica dispersed in a silicone oil. Emulsifiers are added to ensure that the silicone spreads fast and well in the foaming medium.

Is calcium silicate an anti caking agent?
As an effective anti-caking agent, calcium silicate prevents particles from sticking together by absorbing excess moisture and oils. Its porous structure allows it to trap water and oil droplets efficiently, thereby keeping powdery substances dry and free-flowing.Apr 4, 2025
