Abstract (en)
[origin: WO2006094511A2] An electrostatic spraying apparatus, which uses induction to charge different kinds of materials such as pesticides, paint, water or other liquids, has been developed. The electrostatic spraying system depends on a new type of spray apparatus that provides a stream of electrostatic charged droplets. The charged droplets are forced towards the target by the use of air. In the apparatus a positively or negatively charged object is placed relatively to the fluid. The charged object induces a charge in the fluid before and when the fluid reaches the droplet-forming zone. The fluid gets thereby either negatively or positively charged. The object is charged by triboelectrification. The object can be a nylon pipe. The nylon pipe gets positively charged when a cobber ring slides up and down on the nylon pipe because electrons are transferred from the nylon pipe to the copper ring.
