Industrial degreasers are widely used in metal processing, textile, chemical and other industries. Due to formula reasons, degreasers are prone to a large amount of foam during use, which will affect the cleaning effect. How to eliminate the excess foam of degreaser? You can add a degreaser defoamer for defoaming.

Reasons for foaming of degreaser
The degreaser formulation generally contains one or more surfactants and builders. Through the effects of wetting, permeating, dispersing and dispersing, the effects of degreasing and cleaning can be achieved, and the dirt on the metal surface can be eliminated.
The principle of degreaser degreasing is as follows:
1. Utilize the role of surfactants
The hydrophilic group and lipophilic group in the molecular structure of the surfactant are used to adsorb on the interface between the oil stain and the solution. The hydrophilic group points to the solution and the lipophilic group points to the oil stain. The liquid interface tension is greatly reduced. Under the action of agitation, the oil will loosen and easily be dispersed into very fine oil beads and be separated from the surface of the workpiece.
2. The role of surfactants and builders
Utilizing the emulsifying and dispersing effect of surfactants and builders, the oil droplets cannot merge with each other and re-adhere to the surface of the workpiece, thereby achieving a cleaning effect.
Surfactant can change the surface tension of the system. On the one hand, it can achieve a good cleaning and degreasing effect. At the same time, it is easy to cause foam to be easily generated and stabilized. A large amount of foam usually occurs during cleaning and stirring.

The hazards of degreaser foaming
1. Influencing the progress of degreasing and cleaning, affecting subsequent processes, and slowing down the production schedule;
2. Increasing cleaning water will increase cleaning costs and increase the difficulty of cleaning sewage treatment;
3. Too much foam will affect the degreasing effect, and foam will easily cause cleaning oil spots and cleaning residues;

Degreasing agent defoaming program
The degreasing agent is difficult to avoid foaming due to the formulation. A large amount of foam will affect the cleaning effect and increase the cleaning cost. Therefore, degreasers generally require less foaming or low foam formulations. This function can be achieved by adding a suitable defoamer.
A proper amount of defoamer can eliminate excess foam and prevent cleaning oil spots. However, there are many types and brands of defoamers, and defoamers have certain pertinence. Nanhui defoamer manufacturer once again reminds all the friends of the manufacturer that if you encounter the problem of degreaser foam, you can find a professional defoamer manufacturer to solve the problem.
