As a high-performance concrete admixture, polycarboxylate water reducer can significantly improve the fluidity, strength and durability of concrete, so it has been widely used in the construction industry. However, in the use of polycarboxylate water reducer, foam problems often occur, which not only affect the appearance quality of concrete, but also may reduce the performance of concrete. In order to solve this problem, polycarboxylate water reducer defoamer came into being.

In addition to eliminating foam, polycarboxylate water reducer defoamer can also improve other properties of concrete. For example, it can reduce the air content of concrete, improve the density and strength of concrete; it can also improve the fluidity and plasticity of concrete, making concrete easier to construct and shape. In addition, defoamer can also improve the impermeability and frost resistance of concrete and extend the service life of concrete.

Polycarboxylate water reducer defoamer should have excellent defoaming performance, can quickly reduce the surface tension of foam, make the foam break quickly, and can control the re-generation of foam for a long time. It should have a good defoaming effect on different types of foam, including large bubbles and micro bubbles.

Polycarboxylate water reducer defoamer should have good compatibility with polycarboxylate water reducer and will not have a negative impact on the performance of water reducer. After mixing with water reducer, it should be evenly dispersed and will not cause stratification, precipitation or discoloration of water reducer, and will not affect the water reducing effect of water reducer and the performance of concrete.

Polycarboxylate water reducer defoamer plays an important role in the construction industry. It can effectively eliminate foam in concrete and improve the performance and quality of concrete. With the continuous development of the construction industry and the improvement of concrete performance requirements, the application prospects of polycarboxylate water reducer defoamer will be broader.
