Why is surfactant important in a Fog Cannon ® efficency?
The surfactant is used to eliminate the superficial tensions of water particles, concurring to agglomerate grains of powder and precipitate them down to the ground for gravity, thus avoiding any electrostatic rejection between the molecules of powder and water. Once the powder is precipitated onto the ground, the surfactant works to build a thin crust on the surface, keeping the dust there under. What is surfactant? Surfactants are biological molecules able to modify the surface tension of the water. Some types of surfactants are called anionic -i.e. solphate alcohol -, and others cationic – i.e. quaternary ammonium salt. In the two cases above, the polar component is constituted of SULPHONIC IONS ethylene oxide chains and ammonium ions whilst the non-polar component is generally constituted of a long ALIPHATIC chain (often C10-C18). What is the name of Fog Cannon ® surfactant? The name is ECS 89 and is a patented product, VDI certified. Is ECS 89 dangerous to health or to environment?
