Antifoam and defoamer

The rapid development of the concrete industry has placed higher requirements on the admixtures used in concrete, especially the performance of water reducing agents. Polycarboxylic acid high-performance water reducer is the latest generation of water reducer. Its high water reduction, good dispersibility and plasticity retention allow it to rapidly expand the application field and gradually replace naphthalene and melamine and other high-efficiency water reducers. However, due to the molecular structure of polycarboxylic acid water reducing agent, more bubbles are introduced during concrete mixing, the size is not uniform, and the quality of concrete is affected. It is necessary to improve the workability of concrete by adding defoamers to meet the production needs. . The compounding with polycarboxylic acid water reducing agent requires good compatibility of defoamer and water reducing agent, little effect on water reducing rate of water reducing agent, and workability of concrete.

Antifoam and defoamer

Antifoaming agents are also called antifoaming agents. There are many types of antifoaming agents. They are organosiloxane, silicone and ether grafted, containing amines, imines and amides. They have faster defoaming speed and longer foam suppression time. Wider, even harsh media environment such as high temperature, strong acid and strong alkali characteristics. It is widely used to remove harmful foams in the production processes of latex, textile sizing, food fermentation, biomedicine, coatings, petrochemicals, papermaking, industrial cleaning and other industries. Most of the defoamers currently used in concrete mortars are composites based on modified polyethers and modified polysiloxanes.
