Three tips during using defoamers in the production.

1. Turbidity of defoamer:

The defoamer is not compatible with the system used, the second is suspended in it. Then the performance of the defoamer will vary greatly due to the different dosage and color of different materials. But as long as the final defoaming effect is good, the foam suppression time is long.

2. Antifoaming time of antifoaming agent:

defoamers

The nature and content of the silicone oil in the defoamer can determine the length of time the defoamer suppresses the foam in the system and the duration of use. The particle size of the antifoaming agent determines the filtration resistance of the antifoaming agent. During the use, the sewage needs to be filtered multiple times. Both the anti-foam effect and the anti-foam effect will have a certain impact.

3. The defoamer fails:

There are many types of defoamers on the market, and different defoamers have different properties. Some defoamers have poor acid and alkali resistance, which can cause the silicone oil to decompose, which can cause the defoamer to fail. Therefore, it is extremely critical to choose the right defoamer for the industry. Only in this way can we do more with less.

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...

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...

Silicone oil is so widely used! Let’s learn silicone oil production technology

Silicone is so widely used! Let's learn silicone oil production technology Silicone oil is a kind of linear small molecule silicone polymer with Si-O-Si as the main chain and organic groups in the side chain. It is widely used in textile, daily chemical, mechanical processing, chemical, electrical and electronic, medical and health, etc. industry. Silicon oil is usually kept in a liquid state at room temperature. As the molecular weight increases, the viscosity also increases, so viscosity is an important physical property index of silicone oil. 2017 China's silicone oil consumption situation Classification of silicone oil Silicone oil is generally divided into two categories: general silicone oil and modified silicone oil. There is also a class of co-modified silicone oils and derivatives - ternary modified silicone oil Silicone oil properties Silicone oil is generally a colorless, odorless, non-toxic, non-volatile liquid with the following characteristics...
