What factors affect the effect of defoamer
Defoaming agent is widely used, and its products are applied in various industries. So do you know what factors will affect the effect of defoaming agent? Defoaming agent manufacturers introduce to you:
There are many factors that affect defoaming agent, at least two reasons:
1) Defoaming agent is increased by surfactant,
2) Defoaming agent main agent can be absorbed by colloidal resin.
Defoaming ability in static conditions. When the liquid that produces bubbles flows back to the storage tank or directly into the packaging barrel, it is okay if the defoaming is fast.
Defoaming ability of defoaming agent in dynamic conditions
1) Dynamic defoaming effect in a relatively closed small space. Because it involves gas entering the bubble, the external air pressure is reduced in a short time, which is more conducive to the generation and stability of bubbles. Wetting agents and emulsifiers have a shrinking effect on the gas in the bubble. One is nothing, but tens of millions are considerable.
2) Open dynamic defoaming effect, there is no single flexographic printing machine converted into a coating machine, the small space of the glue roller and the inking roller is open and turned at high speed, and the bubble generation speed is quite fast.
Applicability of the machine
1) Temperature. Temperature changes lead to changes in the foam stability and defoaming of surfactants.
2) Customer habits.
The defoamer passed the test in the factory, but failed when it came to the customer. We were puzzled. After visiting the site, we understood that the customer had a large dilution. For the same dilution, the decrease in the foam stability of the emulsifier and wetting agent is inconsistent with the decrease in the defoaming ability of the defoamer.
