Colloids - Chemistry LibreTexts

Sep 11, 2020 · The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many gas particles are trapped in a liquid or solid. Aerosol contains small particles of liquid or solid dispersed in a gas.

Open vs. Closed Cell Foam: Understanding Permeability

Aug 24, 2018 · Created using a similar process as closed cell foam, open cell foam is designated to be vapor semi-permeable as the formation of the cells in the material are broken, rather than closed. Similar to the holes inside a sponge, air can permeate the open cells more easily, making open cell foam more porous and absorbent than closed cell foam.

Firefighting foam - Wikipedia

Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the combustion . Fire-fighting foam was invented by the Russian engineer and chemist Aleksandr Loran in 1902.
