Main components of mineral oil ink defoamer Algeria(2)

metal

anti-delamination

Inorganic hydrophobic particles account for about 10% of the total, and they are evenly dispersed in mineral oil, which is one of the key factors because their hydrophobic strength determines the effectiveness of defoaming performance, which can help ink defoamer Algeria factors reach the surface of the liquid film more easily, allowing the defoaming agent to quickly blend with the liquid film to increase defoaming speed.

Defoaming agents should have the following properties: ① strong defoaming power and low dosage; ② Adding to the foaming system does not affect the basic properties of the system, i.e. does not react with the defoaming system; ③ Low surface tension; ④ Good balance with the surface; ⑤ Good heat resistance; ⑥ Good diffusion and permeability, high positive spreading coefficient; ⑦ Chemical stability, strong oxidation resistance; ⑧ Good gas solubility and permeability; ⑨ Low solubility in foaming solutions; ⑩ No physiological activity, high safety.

Emulsifiers, also known asink defoamer Algeria auxiliaries, aim to increase emulsifying performance, thereby increasing the normal functioning of defoamers, that is, stability. Usually, the proportion is also 10%. Generally, emulsification additives that are compatible with mineral oil and do not affect the appearance performance are selected. When mixed with mineral oil defoamers, they can play a role in the aqueous system and cooperate with defoaming factors to defoaming.
