Why should use defoamer for liquid detergent?

Detergent is a new laundry detergent after detergent and soap. I believe many people have misunderstood laundry detergent. They think that the foam in laundry detergent is getting better and better. Actually it is not, whether it is laundry detergent or detergent. It is not to determine the cleaning ability by looking at the amount of foam, and too much foam, not only clothes are difficult to clean, but the foam that is discharged is also difficult to be decomposed by nature, so the laundry liquid produced by general manufacturers will use laundry liquid defoamer.

The difference between laundry detergent and washing powder:

² The surface active ionic components are different, the laundry detergent is non-ionic, and the laundry powder is anionic surfactant

² The PH value is different. The laundry detergent is neutral, while the detergent is alkaline.

Foam introduction of laundry liquid:

The cleaning ability of the laundry liquid is not because of the foam, but also because of the chemical operation of the surfactant. In general, the surfactant adsorbs the dirt and then flushes away with the water flow, so the foam is completely redundant, just because Under the action of surfactants, it is unlikely that the foam would be without it.

The harmful of foam:

² Excessive residual foam can be a burden on nature

² When customers use too much foam, they will repeatedly clean and waste water and electricity.

² Manufacturers will often leave empty when washing laundry liquid due to excessive foam

² The manufacturer does not add defoamer during production, which is difficult to produce

How to choose laundry detergent defoamer

² Good compatibility, does not affect the transparency of the product

² No residual substance does not affect quality

² With or without floating oil and floating matter after adding

² Does not affect wettability, permeability, emulsification, dispersibility, solubilization, washing function after adding

How do we assess antifoam efficiency ?

How do we assess antifoam efficiency ? Quality of an antifoam is given by two main characteristics : • Knockdown ability or shock effect :Meaning the speed to destroy an existing foam. • Persistence or durability : Meaning the efficiency over time. These two parameters can be assessed by several tests. The main test is the bubbling method. A graduated column with a glass frit in the bottom is required. Foaming water is poured in the column and air at constant flowrate is introduced through the glass frit in the column. Foam is generated by the air and starts to travel up the column. At a determined level of foam, antifoam is injected. By this method several antifoaming agents can be tested. A graph reporting foam height vs time is very helpful to establish the knockdown ability and the persistence for each product. The selected antifoam is the product with the best compromise between shock effect and durability Environmental performance Silicone antifo...

What is a defoamer / deaerator’s purpose in the system?

What is a defoamer / deaerator’s purpose in the system? Defoamers prevent formation of foam during manufacture and application of coatings and printing inks. Foam that is already formed is destroyed and air occlusions are prevented. Deaerators prevent development of air occlusions and pinholes. Why use a defoamer? The occurrence of foam is considered an undesirable but unavoidable phenomenon in coatings and printing inks. The formation of foam interrupts production processes, reduces the effective volumes in the production plant, and leads to unnecessary down time. Foam also interferes with the application process. In printing, foam can cause the ink reservoirs to overflow and can impair ink transfer from the printing cylinder to the substrate. Dried foam leaves surface defects in the paint film. To prevent foam and destroy any foam present, defoamers must be added to the formulation. defoamer vs. deaerator? To eliminate macro-foam on the surface, to prevent air occlusions, and...

Defoamer Test Method

Defoamer testing methods are divided into dynamic defoaming and static defoaming tests. If your foaming environment is different, the recommended test methods are different. There are three main types of foam experiments to characterize the activity of defoamers. Persistence. As we have different experimental conditions in different laboratories and the experiments used in our research to obtain results from existing literature, we will introduce these experiments below. Other methods are sometimes used depending on the particular application. 1． Ross-Miles Foam Tester Features: Tested for strong foaming environments. This experiment is widely used for characterization (1) Foaming of surfactant solution (2) Research and application of foam stability in the presence of defoamer In the foaming system, the defoaming performance test was carried out by circulating bubbling by a Ros...
