In this world, many industries and people contribute silently in their positions and play a huge role but are not known to ordinary people. The defoaming agent industry is such a low-key but very important industry.
For example, in the food industry, the foam may be generated during the fermentation and processing of wheat, fruits and other food ingredients or during the addition of polymer compound emulsifiers. Foam is divided into two types: liquid and solid. Liquid foam is mostly found in drinks such as juice, champagne, and beer, while solid foam is mostly found in the production of bread, cakes, and biscuits.
In most cases, these bubbles must be eliminated as soon as possible when they appear because their presence is likely to damage the normal operation of the machine or lead to poor product quality.
During the processing of oil, natural gas escapes from crude oil, forming a foam phase containing natural gas and a liquid phase containing crude oil, which affects the efficiency of oil separation. Moreover, the molecules carried by these oils have a certain viscosity and are difficult to escape from the oil automatically. Instead, they form foam and affect the production process.
In the pulping and papermaking process of the papermaking industry, the generation of liquid phase foam may also cause insufficient collision between raw materials, thereby prolonging the reaction cycle and reducing reaction efficiency. Most foams will also provide conditions for the growth of aerobic bacteria and even form pump cavitation. The centrifugal pump impeller worn by cavitation will soon lose its function, resulting in a greatly increased production cost of the factory.
When concrete is mixed, the generation of harmful bubbles will not only affect the quality and appearance of the product but also cause insufficient utilization of resources and increase the construction cycle. Air bubbles may even cause material defects, forming a honeycomb structure within the concrete, which can easily lead to an unstable and shoddy project.
Because foam is ubiquitous in industrial production and the harm it causes is difficult to estimate, defoaming agents are necessary.
The production and application of defoaming agents are almost the same as those in modern chemical production. In the first decade of the 19th century, Europe's modern chemical industry was started because there was not enough sugar to eat. However, with the advent of industrial progress and mass production of machines, the problem of machine damage caused by foam attracted the attention of Belgian physicist Prato. At that time, he moved towards soap research based on this phenomenon.
Only in World War II, when industrialization again rose to new heights, Japanese and American chemists began to specialize in defoaming. In 1952, Currie of Dow Corning Company in the United States broke through the technical problem of defoaming agents and put into production the first polyether defoaming agent in 1954. Since then, defoaming agents have become an indispensable part of industrial production, effectively solving various foam problems and reducing losses in industrial production. Currie's invention also became a milestone in the history of defoaming agents.
With the rapid development of the chemical industry, the application scope of defoaming agents is becoming more and more extensive. In industries such as medicine, food, cosmetics, textile printing and dyeing, foam problems must be solved effectively. In these industries, the use of defoaming agents can significantly improve production efficiency product quality and reduce energy consumption.
Today, defoaming agents have developed into a huge industry, and defoaming agents of various types and uses are emerging endlessly. However, although the application of defoaming agents has become quite common, there are still many technical difficulties and challenges in their use in various fields. For example, in some high-viscosity liquids, foam is difficult to eliminate, and the performance requirements for defoaming agents are also more stringent. Additionally, with the increasing awareness of environmental protection, green and environmentally friendly defoaming agents have become a future development trend.
In order to meet the needs of different industries and different application scenarios, defoaming agent manufacturers continue to conduct research and innovation and launch a series of new defoaming agents. These new defoaming agents have stronger defoaming capabilities, a wider range of applications, and are more environmentally friendly.
Concrete defoaming agent is developed using the latest patented technology and is a defoaming agent synthesized from polyether and other ingredients. It is suitable for defoaming under conditions of strong acid and alkali. When the pH value of the defoaming system is 14, several silicone defoaming agents have broken emulsions and drifted oil, losing the physical state that the defoaming agent should have. Reducing or disappearing will also leave unexpected disadvantages in the subsequent processes of defoaming products. This series of defoaming agents can maintain a good physical state at this temperature. It does not break emulsification or float oil, and defoaming is stronger than normal temperature. It has rapid defoaming, long-lasting foam suppression, and is non-toxic and odorless. , will not lead to any pollution to the environment. The amount used when using this product for defoaming is low, and the cost of use is low.
