Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. On-site electrostatic refinishing involves the complete cleaning, resurfacing, and re-coating of items that are at or near where they are used. The electrostatic paint spraying process works so well because of the aspects described before: the paint particles are positively charged and are effortlessly attracted to the negatively charged, grounded surface particles. The electrostatic precipitator process is simple. Also known as ESP, electrostatic precipitators use a series of plates to trap airborne particles. One of the plates in the ESP has a negative charge and the other plate has a positive charge. The coating may be applied to an article via an electrostatic process in which the powder is charged up and sprayed at the article in pulses. Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρός xeros, "dry" and -γραφία-graphia, "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals. As a powder contacts a grounded surface it induces an equal and opposite charge on the surface of the substrate. A current is then forced from the steel cathode, through the aqueous zinc solution, and to the inert anode. Electrostatic cleaning is a great solution for viruses and other strong germs. Fogger (also known as mister): A device that uses a fan and a liquid solution to create a fog (aerosol with small droplets) or mist. Michael Faraday proved that the electricity induced from the magnet, voltaic electricity produced by a battery, and static electricity are all the same. Electrostatic spray surface cleaning is the process of spraying an electrostatically charged mist onto surfaces and objects. This involves submerging the steel (which acts as a cathode) and an inert anode in an aqueous solution containing dissolved zinc salts. Mechanisms which produce natural charge on particle surfaces are shown in Figure 2.The electrostatic charge generated on a particle is proportional to the particle surface area, which is … This means there is no mess and we can come to you.
