Defoamer is small but works well, whose main function is to eliminate foam and inhibit foam regeneration, widely used in all walks of life.However, when using it first time, most workers who have no knowledge of defoamer are bothered by problems that when is the defoamer added and whether added it before using or when foaming .Here we explain to everyone when to add defoamer.
Most users add defoamer when foaming.In fact, not only can the defoamer be added when foaming! Take silicone defoamers as an example.
There are four conventional addition methods for silicone defoamers.
1. Added before foaming: This method shall be antifoaming by beforehand adding defoamer into a system that may produce bubbles.Defoamers can work effectively being in closed containers and devices.
2. Added by continuous drip: Added by continuous drip, defoamers can work effectivly when the foaming liquid is circulating or flowing which shall consume the antifoaming agent. We can use defoamers most economically by controlling the dosage with the help of metering pump(this method is suitable for large-scale production).
3.Added by automatic control: Any foaming liquid does not necessarily foam all the time.There is no accurate pattern for that when foaming and foam sizes.The defoamer is added to supplement the consumption, and it is not necessary to add it when it is not foaming.
Therefore, we can add defoamers by automatic control according to the foaming aura.
4. Added among space: The defoamers can be added one time or periodically if not foaming continously and heavily.Owing to its small dosage, the defoamers should be added in a place where the foaming liquid is
drastically shaken to make the antifoaming agent uniformly dispersed.
It can be added by hand in many occasions.Also, it can be sprayed with a spray gun if foaming violently or to defoam rapidly.
From above, do u have a certain knowledge when to add defoamers?
The defoamer is not necessarily added at the time of foaming. We can add it before foaming to prevent foaming; we can also add it according to the harbinger of foaming…
There are thousands of kinds of foams in the world, while all are feared of defoamers!
