Main components of mineral oil ink defoamer Chad(2)

agent

Polyether polyester modified organosiloxane
An organic polysiloxane with a comb like structure. N+m is about 50-250, and the molecular weight is controlled between 1000-150000. Its compatibility is adjusted by polyethers and polyesters, and the longer the chain, the better the phase compatibility. Polyether modifications are the most common in this category, typically using ethylene oxide and propylene oxide. With the increase of the content of ethoxy groups, their compatibility with water also improves, so it is also possible to synthesize water-soluble siloxane type leveling agents. Ethylene oxide and propylene oxide can be used alone or mixed to control hydrophilicity and lipophilicity. If both ethoxy and propoxy groups are contained, a silicone based leveling agent for both water and oil use is prepared,

anti-flocculation

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 Chad 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.

Emulsifiers, also known asink defoamer Chad 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.
