Anti-foaming Center Position in the Construction Industry - Concrete Defoamer

 Concrete is one of the most important constituent materials in the construction industry, it is a porous structure, made up of a certain proportion of cementitious materials and aggregates, and then add a certain amount of water and the need to add additives, after uniform mixing, moulding, hardening of a kind of artificial stone. It is widely used in the construction industry, machinery industry and even shipbuilding. It can be seen that in the construction industry for defoaming, the first anti-foaming Center should be non-concrete defoamer. Below I will take you to understand the concrete blistering and concrete defoamer.

The hazards of concrete blistering:
1, Too many bubbles, reducing the cross-sectional area of the concrete, resulting in the internal concrete is not tight, thus affecting the safety of the building;
2, Too many bubbles, the effective thickness of the concrete to protect the steel bar is reduced, accelerating the process of carbonation of the concrete surface;
3, Too many bubbles, after the concrete solidification and hardening may appear honeycomb wall, extremely affect the aesthetics of the building.

Concrete defoamer performance:
1, Fast defoaming speed, long lasting foam suppression time;
2, Good dispersion performance, in the mud is also easy to disperse;
3, A small amount of additive can achieve the desired antifoaming effect;
4, PH value is wide;
5, Non-toxic and harmless, will not cause pollution to the environment;
6, Easily compatible with the foaming medium in the material.

Concrete defoamer use method and storage conditions:

Concrete defoamer is available for direct use to ensure its uniform dispersion. In order to exert the continuous defoaming ability of the defoamer, it is recommended to use a metering pump to continuously drip, and the recommended addition amount is 0.1%-0.5%.

In addition, because there is a certain amount of air bubbles in the concrete, can make the hardened concrete resistance to freezing and thawing, durability has been significantly improved, so the specific use of concrete defoamer should be based on the characteristics of manufacturers of concrete, to do the appropriate experiments and then add, but also in the diluted for use, add less than to achieve the effect of anti-foaming, add more defoamer may appear to be insoluble, which affects the characteristics of the concrete.
