What is Foaming agents

Chemical foaming agents are a class of foaming agents that are solids or liquids at room temperature and, on heating, decompose at a particular temperature, releasing a gas such as nitrogen, carbon dioxide, or carbon monoxide. These compounds have a multitude of uses in many industries, including food and agriculture, cosmetics, and medicine. Products containing surfactants include shampoo, dishwashing detergent, emulsifiers, foaming, wetting, and dispersing agents, creams, lotions, toothpaste, foods, and pharmaceuticals. Foaming agents facilitate the formation of voids (cavities filled with gas) in areas that would normally be solid plastic. This not only reduces the weight of the finished product but also reduces the amount of plastic used. Lighter-weight products lower transportation costs and reduce environmental impact. Other ingredients also increase the foam of a soap. Sugar or food rich in sugars. Food rich in fats. Natural foaming agents, or rather ingredients, would be coconut oil, babassu oil, palm oil, and castor oil. Water was used as a foaming agent, and NaCl was used as porogen to achieve an open-cell structure. The polyether-polyurethane samples were processed in a heated press and achieved a porosity of 64%. A foaming agent for cellular concrete, containing about 20-25% by weight of powdered polyvinyl chloride, about 40-45% by weight of a water-soluble alkylnaphtliylene sulphonate in which the alkyl groups have 4-10 carbon atoms, and about 13-17% by weight of a member of the class consisting of lower alkyl esters of … foaming agents – assist in the formation of liquid films, lamellas around air bubbles (mostly at air-water interface) – note that similar to emulsions there is a difference between formation and stabilization. Emulsifiers – ease droplet break-up and stabilize oil or water droplets in the continuous water or oil phase.

However, not all foaming agents are as harmless as they may seem. Some foaming agents are linked to health concerns and should be avoided. Foam drainage technology has entered the personalized application stage, endowing foam with intelligent responsiveness, making it foam at wellbore temperature and defoam at ground temperature, removing the defoaming process of conventional foam drainage technology, and simplifying the foam drainage process. It is of great research value to reduce the cost and expand the application range of foam drainage gas production. Sodium Lauryl Sulfate (SLS) is responsible for the foaming in toothpaste. SLS is a common detergent in many personal care products. It works well in toothpaste because it doesn't affect the flavor or how the other ingredients work. And it has mild antibacterial properties. We have two foundational chemicals involved in the foaming of PU. Isocyanates, by definition, have the functional group R−N=C=O. Polyols, by definition, contain multiple hydroxyl or −OH functional groups.

In the later stage of natural gas exploitation, due to the low pressure of the gas well and the decrease in drainage capacity, the large amount of liquid produced by the gas well leads to a decrease in exploitation efficiency. Foam drainage technology is widely used in natural gas recovery because of its simple operation and excellent drainage effect. In this process, the foaming agent is added to the bottom of the well so that the bottom hole fluid is stirred by natural gas and fully mixed with the foaming agent to form a large amount of foam, reducing the friction loss and gravity gradient in the tubing during the self-flowing stage to effectively reduce the bottom hole back pressure and make the liquid be continuously lifted. The regeneration capacity of the foam is very strong. When its aqueous solution is carried to the ground pipelines and separation equipment, it is repeatedly agitated, resulting in foam accumulating in the separator. When the surfactant is excessive, or the foam produced is too stable, this phenomenon is particularly serious. A large amount of foam will be brought to the gathering and transportation pipeline, causing blockage and resulting in an increase in the collection and transportation pressure. Therefore, it is necessary to inject a defoamer at the entrance of the separator to achieve defoaming, inhibit the regeneration of foam, and facilitate the separation of gas and water. However, the addition of defoaming agents will limit the recycling of foaming agents, and the introduction of a defoaming device will increase the production cost. Various commercially available antifoam agents were tried in an attempt to prevent this foaming problem but without success. It has now been found that this foaming phenomenon can be eliminated by the relatively simple expedient of adding a small amount of glycerin to the reaction mixture.
