In busy factories, bottles of clear liquid lie quietly on shelves, they are the protagonists of chemical production - air bleed agent and defoamer. These seemingly ordinary chemicals have the amazing power to change the properties of liquids. So how do you know exactly how much? This is not only the skill of chemical engineers, but also the common sense that every chemical practitioner must master.


Entrainment. That name sounds like a magician's spell. Its main function is to produce a large number of bubbles in the liquid, thereby improving the reaction speed and heat transfer efficiency of the liquid. Imagine that under the conditions of high temperature and pressure, the air entraining agent is like a lively elf, shuttling in every corner of the liquid to wake up the sleeping substance.


Dosage mystery
The amount of air entraining agent is like a mysterious formula that needs to be adjusted according to specific chemical reactions and environmental conditions. Too much entraining agent may cause the liquid to expand too much and even cause danger; Too little entraining agent may not achieve the desired effect. Therefore, mastering the amount of air entraining agent is like mastering the key to magic.


In actual operation, engineers will determine the best amount of air entraining agent according to the nature of the reactant, temperature, pressure and other factors through testing and experience accumulation. This requires not only a deep understanding of chemical principles, but also a keen insight into experimental results




The magic of defoamer


In contrast to air entraining agents, antifoamers have the opposite effect, which is to eliminate the bubbles that have been created and let the surface of the liquid calm down again. During the fermentation process, the presence of bubbles can interfere with the growth of microorganisms and reduce the quality of the product. This is where defoamer comes in handy

The beauty of dosage
The amount of antifoaming agent is also an art. Appropriate amount of defoamer can quickly eliminate bubbles and restore the stability of liquid. Excessive defoamer may destroy the balance of the liquid and affect the subsequent process. Therefore, the amount of defoamer needs to be precisely controlled according to the specific situation.


When selecting a defoamer, engineers consider factors such as its defoaming ability, stability, and compatibility with liquids. At the same time, the dosage will be optimized through experiments to achieve the best results.


Wisdom in practical application




In practical applications, the dosage of air entraining agent and defoamer is not isolated. They often work together with other chemicals to affect the entire production process. Therefore, to master the amount of air entraining agent and defoamer, it is necessary to consider the operation of the entire production system.


Once, while visiting a chemical plant, I saw engineers adjusting the amount of entrained air and defoamer in a mixture of solutions. They looked at the color, smell and bubble size of the solution and adjusted the amount until the desired effect was achieved. This scene let me deeply understand the essence of the amount control of air entraining agent and defoamer.


Challenges and opportunities for the future
With the advancement of science and technology and the improvement of environmental awareness, the demand for air entraining agents and defoaming agents in the chemical industry is also changing. In the future, we will need to be more precise about how much of these chemicals are used to achieve more efficient and safe production.


We also need to be concerned about the environmental impact of these chemicals. How to reduce environmental pollution while ensuring production efficiency is a problem that every chemical practitioner needs to think about.
