melunesteitä
Melunesteitä, or antifoams, are chemical additives used to suppress or inhibit foam formation in various industrial processes and products. Foam is a dispersion of gas in a liquid, and while sometimes desirable, it can be problematic in many applications, causing inefficiencies, product defects, and safety hazards. Antifoams work by reducing the surface tension of the liquid, disrupting the stability of the foam lamellae, and causing the bubbles to coalesce and break.
The mechanism of action for antifoams typically involves their low surface tension and insolubility in the
A wide range of substances can function as antifoams, including mineral oils, silicone oils, fatty alcohols,
