The role and selection of degreasing agents and defoaming agents

Degreasers are an important part of cleaning agents and have significant effects in removing grease and organic dirt. However, the cleaning process is often accompanied by the generation of a large amount of foam, which not only affects the cleaning effect, but also makes the operation difficult. To solve this problem, we add defoaming agents to the degreaser. Next, we will explore the role and selection criteria of degreasers and defoamers.
1. The function of degreasing agent and defoaming agent

1. Improve cleaning performance: The presence of foam will reduce the contact area between the degreaser and the grease surface, limiting the ability of the detergent to directly contact dirt. Defoaming agents can destroy the foam structure and reduce the surface tension of the liquid, allowing the cleaner to better contact the dirt surface and improve the cleaning effect.

2. Improve operational convenience: Excessive foam will make cleaning operations difficult. For example, during the cleaning process, the foam may overflow the container and block the line of sight, affecting the accuracy and efficiency of the operation. Adding defoaming agents can effectively control the formation and expansion of foam, making the cleaning process smoother and more convenient.

2. Selection of degreasing agent and defoaming agent

1. Tolerance: Defoaming agents should have stable properties and not be affected by temperature, pH value and chemical environment. During the cleaning process, it may be affected by different temperatures, different pH levels and different chemical compositions.

2. Compatibility: Defoaming agents cannot affect the cleaning performance of the degreaser, should not have a negative impact on the cleaning effect, and should not have adverse chemical reactions with the degreaser.

3. Easy to clean: The defoaming agent needs to be completely removed after cleaning without leaving any residue. Residual defoaming agent may cause secondary pollution or affect the surface condition of the object being cleaned.
