During the chemical cleaning process, when these reagents react with the dirt on the surface of the equipment being cleaned, foam is easily generated due to the release of gas produced by the chemical reaction, the stirring or circulation operation of the cleaning liquid, etc. Foam will occupy a lot of space and reduce the effective contact area between the cleaning liquid and the surface being cleaned. This makes it impossible for the chemical reagents in the cleaning liquid to fully act on the dirt, thereby reducing the cleaning efficiency and prolonging the cleaning time. The emergence of defoaming agents for chemical cleaning has become a key auxiliary agent to solve the problem of foam.

Characteristics of defoaming agents for chemical cleaning

1. Effective defoaming: During the chemical cleaning process, once foam is generated, the defoaming agent should be able to work quickly and significantly reduce the height and amount of foam in a short time, so that the cleaning process can proceed smoothly.

2. Wide chemical compatibility: Defoaming agents for chemical cleaning have good compatibility with various chemical substances such as acids, alkalis, oxidants, and reducing agents, and will not react negatively with the chemicals in the cleaning liquid.

3. Chemical stability: Defoamers for chemical cleaning can maintain a stable defoaming effect even in harsh environments such as high temperature and high pressure, and will not affect the original performance of the cleaning agent.

For some small chemical cleaning operations, defoamers can be added directly to the cleaning solution. When adding, pay attention to slow stirring to make the defoamer evenly dispersed in the cleaning solution. Generally, defoamers are added according to a certain proportion of the total amount of the cleaning solution. This proportion needs to be determined based on factors such as the composition of the cleaning solution, the foam situation, and the cleaning requirements.

Defoamers for chemical cleaning play a vital role in the chemical cleaning process. They can effectively solve the foam problem and ensure its smooth progress in the chemical cleaning process. Its continuous development and innovation will help improve the efficiency and quality of chemical cleaning, while meeting environmental protection and other requirements.
