Main components of mineral oil ink defoamer Guatemala(1)

UV

Explanation in reference book
An agent that promotes the uniform dispersion of material particles in the medium to form a stable suspension. Dispersants are generally divided into two categories: inorganic dispersants and organic dispersants. Commonly used inorganic dispersants include silicates (such as water glass) and alkali metal phosphates (such as sodium tripolyphosphate, sodium hexametaphosphate, and sodium pyrophosphate). Organic dispersants include triethylhexyl phosphoric acid, sodium dodecyl sulfate, methyl pentanol, cellulose derivatives, polyacrylamide, gum, fatty acid polyethylene glycol esters, etc.

The main component of mineral oil ink defoamer Guatemala is mineral oil, or any other oil that is insoluble in the foaming medium, as the carrier, accounting for approximately 50% to 70%. Its specific gravity is the key. Too much will affect its solubility and emulsification, while too little will affect its stability and effectiveness.

agent

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 Guatemala 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.
