What is concrete defoamer

As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the concrete defoamer in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the concrete defoamer.

What is a concrete defoamer

Concrete is a stone mixed with water, sand, stones and some chemical additives, if necessary, in a particular proportion. Foaming occurs when concrete is made due to agitation. The appearance of a large amount of foam will lead to a decrease in the strength of the concrete and bring about quality problems.


So, how does foam in concrete form?

1. Concrete is vibrated during the pouring process, and local liquefaction has water analysis and gas floating, and it accumulates in the gathering area to form foam;

2. When mixing concrete, to increase the strength of concrete, a certain amount of chemical additives are often added. Most of these additives contain surfactants, which are easy to generate foam;

3. Air is mixed in during the vibration and stirring process of the equipment to form foam;

4. The steel formwork is too tightly closed, and there is no vent hole. When the concrete is cut, a kind of air pocket is generated, and then air bubbles are formed.


If the foam problem is not solved in time, what harm will concrete foam cause?

1. The generation of a large number of air bubbles causes too many pores on the surface of the concrete, and the phenomenon of a pockmarked surface appears, which affects the surface appearance of the concrete;

2. The production of foam will affect the mechanical strength and construction efficiency, reduce the life of the building, and cause relatively large quality problems;

3. Decrease the corrosion resistance of the concrete structure. Due to a large number of air bubbles on the concrete surface, the adequate thickness of the steel protective layer is reduced, and the carbonization process of the concrete surface is accelerated;

4. Due to the large air bubbles, the cross-sectional volume of the concrete is reduced, resulting in the uncompacted interior of the concrete, thereby reducing the strength of the concrete.


How does the concrete defoamer solve the problem of concrete foaming?

Its mechanism of action is mainly divided into three forms: foam breaking, foam suppression and defoaming. When added to concrete according to the method of use, the chemical components contained in it will reduce the surface tension of water and achieve rapid foam breaking; and it has good compatibility, no oil drift, no precipitation, and no impact on the strength of concrete; at the same time, the applicability is also It is pervasive, and it can quickly break foam and suppress foam for a long time in the environment of strong acid, strong alkali and high temperature.

The current international situation is highly uncertain, and its economic impact has not been able to be assessed properly. In addition, rising energy and commodity prices and supply chain disruptions are expected to push the price of the concrete defoamer higher.
