Gypsum self leveling defoamer plays a key role in improving material stability, mainly through the following aspects:

1、 Eliminate foam and bubbles. Gypsum self leveling is easy to produce foam and bubbles during construction and use. These foam and bubbles will not only affect the fluidity and flatness of materials, but also form pores and defects after curing, reducing the compactness and strength of materials. Defoamers can effectively reduce the surface tension of liquid, destroy the stability of foam and bubbles, make them break quickly and release the wrapped gas, thus significantly improving the compactness and stability of materials.

2、 Improving fluidity and uniformity, the addition of defoamers can also enhance the fluidity and uniformity of gypsum self leveling materials. By reducing the obstruction of foam and bubbles, the materials can flow more easily and be distributed evenly, so that the construction personnel can operate more easily and improve the construction efficiency and quality. This improvement in fluidity and uniformity helps ensure that the material forms a complete and continuous surface after curing, thereby enhancing overall stability.

3、 Reduce pores and cracks. The existence of foam and bubbles in gypsum self leveling materials will also increase the risk of pore and crack formation. These pores and cracks are weak links inside the material, which are prone to damage when subjected to external forces. Defoamers reduce the generation of pores and cracks by eliminating foam and bubbles, thus improving the crack resistance and durability of materials and further improving the stability of materials.

4、 Improving overall performance, in addition to the direct effects mentioned above, defoamers can also enhance the overall performance of gypsum self leveling materials through synergistic effects with other additives. For example, some defoamers can be used in combination with enhancers, retarders, etc. to form a composite effect, thereby improving the strength, durability, and other properties of the material, indirectly enhancing its stability.

In conclusion, gypsum self leveling defoamer significantly improves the stability of materials by eliminating foam and bubbles, improving fluidity and uniformity, reducing pores and cracks, and improving overall performance. When selecting and using defoamers, it is important to pay attention to the above precautions to ensure optimal effectiveness.
