ABSTRACT:
A sprayer, such as an electrostatic rotary bell-shaped sprayer is made from a material comprising carbon fiber, teflon and polypropylene. An exemplary material comprises about 30% carbon fiber, about 5% teflon, and about 65% polypropylene. When used for electrostatic spraying, the sprayer provides a mist containing an electrical charge equal to at least 20% of the charge applied to the sprayer. For example, when 100,000 volts are applied to the sprayer, the downstream mist contains a charge of at least 20,000 volts. The sprayer can also include a plurality of pits arranged near its outer edge in an offset matrix pattern producing therebetween two sets of intersecting surface lines. The sprayer can further include a deflection part with a pointed rear center section positioned opposite an opening in a base part. A plurality of axial passages positioned around the pointed section and extending toward a front surface of the deflection part allow for the passage of cleaning fluid therethrough. The device according to the invention provides better atomization and better adhesion of paint to a grounded article such that less paint is required than is required with conventional devices, and further provides ease of cleaning and increased durability.
