Foam generation is a common issue in the construction materials industry, particularly in cement, concrete, and plaster production. The presence of foam can lead to defects such as air pockets, reduced material strength, and inconsistent surface finishes. To mitigate these challenges, construction materials defoamers are widely used to remove foam and improve material quality. Below are several effective methods for eliminating foam in construction materials using defoamers.

1. Direct Addition of Defoamers
One of the most common methods is the direct addition of defoamers to the cement, concrete, or plaster mixtures. The defoamer is typically added at a low dosage directly into the mixture during the production process. This method ensures that the defoamer is evenly distributed, helping to break down and prevent foam formation, resulting in stronger and more consistent material.

2. Surface Application
In some cases, foam may form on the surface of the mixture during the production process. A surface application of defoamer can be effective in such scenarios. This method involves spraying or applying the defoamer directly onto the foam on the surface of the material. The defoamer penetrates the foam layer, causing it to break down quickly and reducing the risk of defects in the final product.

3. In-line Injection
For large-scale construction material production, an in-line injection of defoamer into the production system is highly effective. This method involves injecting the defoamer directly into the processing lines where cement or concrete is being mixed. It allows for continuous foam control and ensures that the defoamer is integrated throughout the entire production process. This is especially useful in high-volume industrial settings.

4. Batch Pre-treatment
In certain situations, construction materials can be pre-treated with defoamers before they are processed. This is done by mixing the defoamer with raw materials during a pre-treatment phase, ensuring that foam is controlled throughout the entire production cycle. This method is effective for applications that require precise foam control to achieve optimal material performance.

5. Application via Admixtures
Construction materials often contain various admixtures to improve their properties. Defoamers can be incorporated into these admixtures to provide foam control throughout the production and curing process. This method ensures consistent foam reduction without the need for additional steps or treatment.

By using these methods to eliminate foam, construction material producers can significantly enhance the quality, durability, and overall performance of their products.

Building materials is a general term for materials used in civil engineering and construction, including cement, concrete, wood, stone and a series of construction and decoration materials. In the production and actual use of building materials, foam often appears due to irrational grading and other reasons.

Why does foam appear in the production and use of building materials?
1. Unreasonable grading, too much coarse aggregate and too little fine aggregate lead to large gaps in the building materials, which is easy to produce foam;
2. Inappropriate size of aggregate, too high content of needle and flake particles, leading to the emergence of foam;
3. In order to improve the performance and strength of building materials, often add a certain proportion of chemical additives, such additives belong to the surfactant, with foaming properties;
4. The mixing operation of the equipment and the uneven surface of the substrate make it difficult for air to escape and form foam.

What are the hazards of foam in construction materials?
1. A large amount of foam will affect the performance and strength of the product, so that the strength of building materials does not meet the standards and cause quality problems;
2. Too much foam will also affect the appearance of building materials, easy to make the surface of building materials uneven, defects;
3. Excessive foam will slow down the production process of building materials, extend the construction cycle of building materials, resulting in unnecessary costs;
4. A large number of foam is difficult to remove cleanly, will remain part of the construction equipment, resulting in a decrease in the utilization rate of construction equipment, shortening its service life.

In the face of the various problems brought about by the blistering of construction materials, why would we recommend building materials defoamer? What are the advantages and characteristics?
1. Fast defoaming and foam suppression, added to the building materials can quickly penetrate the foam inside to achieve defoaming and foam suppression;
2. Stable performance, will not affect the performance and strength of building materials after use, and will not change the color and appearance of building materials;
3. Good water solubility, fast dispersion, once added can be quickly dispersed, no new precipitation, no oil bleaching.

Oilfield drilling fluid has an important role in the process of oilfield extraction, can clean the bottom of the well, keep the bottom of the well clean, lubricate the drill bit drilling tools to reduce wear and tear, etc. It is a circulating fluid used in the drilling process, which is a mixture of liquids, solids, and chemical treatment agents. Solid-phase substances in drilling fluid mainly refer to slurry clay, aggravating substances, drill cuttings and other substances, in the process of oilfield drilling fluid often appear a lot of foam, too much foam will bring about some adverse effects, so it is necessary to use oilfield drilling fluid defoamer to solve the foam problem.

Oilfield drilling fluid is divided into three categories according to the dispersing medium: water-based drilling fluid, oil-based drilling fluid and gas-based drilling fluid. Oil and gas formations have certain requirements for drilling fluids, which need to be matched with the rocks of the formation, and the components of the drilling fluids do not have precipitation reactions with the formation fluids to prevent scaling and other damages, and they do not have emulsification reactions with the formation fluids, and the surface tension of the drilling fluids should not be too high. In order to prevent damage to the oil and gas formation caused by solid particle plugging, the solid phase content should be reduced as much as possible.

There are many reasons for oilfield drilling fluid foaming, in the drilling process, the gas in the formation will invade the drilling fluid, and these gases will not be able to escape in time, leading to foaming of the drilling fluid; oilfield drilling fluid contains many surface-active substances, which have foaming characteristics, leading to foam generation; the decomposition of the treatment additives added in the process of drilling will produce gas, which will generate gas bubbles, and due to the mixing operation of the equipment, which results in a large amount of air being The air will be swept into the oilfield drilling fluid, which will lead to foam generation.

Excessive foam will affect the progress of oilfield drilling and normal processes, resulting in reduced drilling efficiency, cost increases, affecting the drilling process; a large number of foam is not eliminated in a timely manner will be gathered in the drilling field inside the drilling site, resulting in the drilling site environment is affected, as well as the waste of drilling fluids; the drilling fluid bubbles will cause blowout phenomenon, affecting the efficiency of the mud pump and reduce the pump pressure, which affects the entire drilling and engineering.
In order to reduce the harm brought by excessive foam, we choose to use oilfield drilling fluid defoamer to solve the foam problem. The defoamer has the characteristics of fast defoaming speed and long foam suppression time, which can quickly eliminate a large number of foams in the oilfield drilling fluid and play the purpose of defoaming and foam suppression; it is resistant to high temperature, acid and alkali, and can stably play the function of defoaming and foam suppression under the environments of high temperature, strong acid and alkali; it has a wide range of applicability and stable chemical properties, and it will not affect the performance and effect of the oilfield drilling after its use.

In the production process of gypsum, we can often find that in order to maintain the balance of the circulatory system of the desulfurization plant, often need to remove a certain amount of wastewater, and this wastewater often contains a lot of heavy metals and harmful suspended solids, therefore, in order to ensure that the subsequent water treatment can be a good operation, the subsequent water treatment manufacturers will also be put into the appropriate amount of desulfurization wastewater treatment defoamer in order to reduce the water source foaming and subsequent foam suppression has made an outstanding contribution.

We all know that the desulfurization wastewater formed by the construction steps, after a variety of filtration and processing, the concentration of wastewater from the reaction pool slowly out of the wastewater, which not only takes away the excess suspended solids, there are a large number of saturated sulfites, which has caused a major difficulty in water treatment, so this wastewater often needs to be recycled many times in order to meet the discharge standards. However, with the recycling of wastewater filtration, a large number of microorganisms and foam groups will grow from it, problems will arise, such as clogging of filters, chemicals can not be directly to the water source, wastewater treatment time is longer and so on.

The role of defoamer is to separate the gas from the liquid film from thick to thin until the process of rupture. To add antifoaming agent to the foaming liquid, antifoaming agent particles quickly dispersed in the bubbles on the surface of the liquid film, and then gradually to the liquid film surface expansion, so that the liquid film is getting thinner and thinner and ultimately rupture. Antifoam agent in water can also adsorb microorganisms to reduce the volatilization, reduce the formation of foam factors, to achieve the efficacy of long-term foam suppression.
