Atomization Pressure

Definition - What does Atomization Pressure mean?

Atomization pressure refers to the force per unit area in a nozzle or spray gun that is required to transform bulk liquid into fine particles. This bulk liquid is usually a corrosion preventative coating intended to be applied on a metallic surface in an even pattern.

The atomization pressure may also be known as the atomizing pressure.

Corrosionpedia explains Atomization Pressure

The atomization pressure affects the size of spray droplets and spheroids generated during spraying applications. A higher atomization pressure tends to narrow and reduce droplet sizes and vice versa. However, an increase in the liquid spray rate increases droplet size and also generates a wider range of sizes. Despite this, atomization pressure appears to have a greater impact on the size of the droplets and facilitates an even distribution. Hence, the oversized particles can be decreased and more uniformly sized with the use of relatively higher atomizing pressures.
