What Is Electrostatic Spraying?
Air and liquid enter the rear of the nozzle separately. The air moves through the nozzle under pressure and meets the liquid at the nozzle tip, causing the formation of spray droplets that are 30 to 60 microns in diameter. At the tip of the nozzle is a tiny electrode which applies an electrical charge to the spray. The attraction to the target’s surfaces relates to Coulomb’s Law, which states that any two charged objects will create a force on each other. The charge on the droplets, though small, pulls the spray towards the target at 75 times the force of gravity. The spray droplets can reverse direction, moving against gravity, to coat all sides of an object.
How does it Work?
Step 1 – As the spray is atomized the droplets pass an electrode inside of the nozzle. Electrons are induced onto the droplets and they leave the nozzle with a high negative charge.
Step 2 – The droplets have a force of attraction of 75 times that of gravity allowing them to reverse direction, against gravity to coat hidden surfaces that would normally be missed.
Step 3 – The droplets are carried in an air stream towards the target. The closer the charged droplets get, the stronger the electrostatic force.
Below are the high volume suitcase and cart sprayers. These are electric plug in units, ask us about battery operated units also available.
