How to choose defoamer for industrial cleaning?

Beer bottle cleaning defoamercleaning defoamer

In the cleaning of beer bottles, defoamers are generally required to be resistant to high temperatures and strong alkalis, and solid defoamers are used more often. It is recommended that you can choose solid silicone defoamers. The carrier is easy to dissolve the antifoaming agent. If the carrier is relatively poor and difficult to dissolve, then precipitation will occur and the effect will be affected.

Circuit board cleaning defoamer

Circuit board cleaning and defoaming agents are mainly used in two processes, one is development, and the other is film / etching. The process is different and the products selected are different. Generally, a little more silicone defoamer is selected during the development stage, and the cost performance isindustrial cleaning defoamer outstanding. However, at the time of the film / etching stage, non-silicon products must be considered at this time. Circuit board cleaning and defoaming agent is mainly added in the reflow tank, and the defoaming agent is mainly used in the development stage.

Steel plate cleaning defoamer:

Of the steel plate cleaning and defoaming agents, the most demanding is galvanized steel. At this time, polyether type defoamers are selected. For other less demanding cleaning, silicone defoamers can be selected. Solid and liquid can be considered. The key is Effect.

Other cleaning defoamer

In addition to the above cleaning industry, which is only for playing, there are also parts cleaning. It is recommended to choose fatty alcohol defoamers, for automotive coatings to use mineral oil defoamers.
In the industrial cleaning industry, the performance of antifoaming agents is emphasized. In the field use process, if the antifoaming agent needs to be diluted, please could you contacted us for diluted method or go forward to: www.ywlchemical.com get more details. otherwise silicon plugging may occur.
Hope These can help you choose the right industrial defoamer for you.

Why Foam could be so inconvenient ? A light foam is generally not problematic in most applications however heavy foaming can often lead to various processing problems. These problems range from inaccurate readings from control and measuring equipment such as temperature, level and density controllers to poor mixing of reactants in chemical reaction vessels and products hanging in the foam, all too often leading to losses in production. Finally the presence of foaming can give a bad image of the way a process is operated in the eyes of a customer. The presence of foam in discharged effluent can cause complaints from local people and authorities even if the foam is harmless to people and the environment. How do silicone defoamers work ? Foam is a gas dispersion in a liquid or solid continuous phase. Foam iscreated by the surfactants which are at the air/liquid interface. Therefore air bubbles occur and are stabilised by the surfactants. Today, silicone antifoams are thebest solution to a...

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...
