The cleaning agent is mainly used for cleaning and decontamination through saponification and emulsification. However, during the cleaning process, due to the formula and the cleaning process, a large amount of foam is prone to appear, and it is necessary to add a cleaning agent defoamer to defoam. The cleaning agent defoamer with good performance are not only small in dosage, rapid defoaming, and good stability, but also relatively convenient to use.

Cause analysis of foaming of cleaning agent
The cleaning agent is a cleaning medium that achieves cleaning by means of the wetting, dissolving, emulsifying, saponification, chelating and other functions of surfactants, emulsifiers, penetrants, etc. contained. Cleaning agents can be divided into water-based cleaning agents, semi-aqueous cleaning agents, and organic solvent cleaning agents.
1. Water-based cleaning agent refers to a cleaning agent in which all components of the cleaning agent can be dissolved in water, that is to say, this cleaning agent can be completely miscible with water and form a uniform solution (one phase). This cleaning agent is alkaline and acidic, and it is a widely used cleaning agent in industry.
2. Semi-aqueous cleaning agent means that the components of the cleaning agent contain organic solvents. These organic solvents are dispersed in water by the action of surfactants and form an emulsion, so semi-aqueous cleaning agents are also called emulsifying cleaning agents. This cleaning agent is dissolved in water to form an emulsion, which means that this emulsion is heterogeneous (two-phase). This cleaning agent is acidic and alkaline, but both are weaker than the water-based cleaning agent, and its use is far less than the first cleaning agent. It is mainly used in occasions with a small amount of oil and easy to clean.
3. Organic solvent cleaning agent means that all the components of the cleaning agent are organic solvents (one phase). This cleaning agent is neutral and is mainly used to clean precision mechanical parts or electronic products.
The cleaning agent mainly uses surfactants and other substances to achieve cleaning and decontamination effects, but these substances can also easily cause a large amount of foam. A large amount of foam will affect the cleaning effect, resulting in unclean cleaning, residues, spots, etc.

Cleaning agent defoaming solution
A large amount of foam in the cleaning agent will have a negative impact on the cleaning process. The foam can be defoamed and suppressed by adding a cleaning agent defoamer.
In view of the easy foaming characteristics of the cleaning agent formula, the cleaning agent defoamer developed and designed specifically is a compound industrial cleaning defoaming agent. Refined from various active additives of siloxane, it has fast defoaming and good foam suppression performance.
The principle of rapid defoaming of Nanhui cleaning agent defoamer is as follows:
Sprinkle this defoamer on the foam, and when it adheres to the foam, it will dissolve into the foam liquid, which will significantly reduce the surface tension there. Because these substances are generally less soluble in water, the reduction in surface tension is limited to local areas, while the surface tension around the foam hardly changes. The part with reduced surface tension is intensively pulled around, stretched, and finally broken.
Advantages of Nanhui cleaning agent defoamer:
1. Professional factory direct sales, perfect service;
2. Provide free sample service, which can be obtained by contacting technology;
3. Good stability, resistance to acid and alkali, high temperature and other environments, can continue to defoam and suppress foam.
