Three tips for testing viscosity of

defoamer/antifoaming

Many customers make certain demands on the viscosity of the Defoamer when purchasing the product, but the different supplier has different standard, how to check the authenticity of the corresponding viscosity coefficient? Now let Invely help you.

Temperature affects viscosity

The temperature will affect defoamer viscosity seriously.the viscosity of viscosity of defoamer will be relatively higher in winter under normal circumstances, but the viscosity of the defoamer will be lower in the summer. In this case, if you test the viscosity of the defoamer, you must pay attention to the room temperature. It is recommended that you try to keep the room temperature at about 23 degrees when testing the viscosity. This will ensure the uniformity of the viscosity test.

Speed Viscosity Tester or Mechanical Viscosity Tester?

Many customers will encounter such a problem when testing the viscosity of defoamer. which one is better?Speed Viscosity Tester or Mechanical Viscosity Tester? In fact, every instrument has its own advantages, but it also has its own shortcomings. so we must use it instrument correctly,and then they can test the viscosity accurately. The speed-sensitive viscosity test should pay attention to whether the viscosity of the defoaming agent is consistent in the surface and bottom layers of the package, otherwise the test result is not accurate; and the mechanical viscosity test should pay attention to the rotation speed.

Points of attention when testing

In addition to the instrument and temperature during the test, there is also a point to note that the defoamer should be thoroughly stirred and then tested. Because the defoamer in the upper layer will be thinner, and the lower layer will be thicker after transported,Therefore, for accurate testing, it is necessary to thoroughly stir the defoamer before it can be measured.
The above is some tips of the viscosity test. I believe that if you can pay attention to the above points during the test, it can help you correctly test the viscosity of defoamer to help you produce.

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...
