The dry powder is loaded into a spray gun that uses compressed air to propel the powder toward the furniture. The gun also applies an electrostatic charge to the powder particles as they’re sprayed, so they can stick to the metal surface. Step 5: Curing Once coated, the furniture is mov...
powder coating, and electrophoresis. Each method has its own uses in various circumstances. Sometimes, you will need to use a certain coating method, while other times, you might choose any coating method that will suit your preferences the most. Here, we want to...
But when the layer is hit by light, the energy of the photons liberates electrons and allows current to pass through! These newly freed electrons are what neutralizes the positive charge coating the drum to form the latent image. It's easy to imagine how you might project a copy of an ...

Like the paint-propellant mixture inside a spray can, compressed air is used to drive atomized particles of paint through a spray gun onto the target. These particles are very fine and resemble dust, or a powder. And just as with the aerosol can, the particles acquire an electrical charge ...
The positive layer has "holes" -- openings for electrons; the negative layer has free electrons floating around in it. When an electric charge strikes the semiconductor, it activates the flow of electrons from the negative to the positive layer. Those excited electrons emit light as they flow ...
To send a current through gas in a tube, then, a fluorescent light needs to have two things: Free electrons and ions A difference in charge between the two ends of the tube (a voltage) Generally, there are few ions and free electrons in a gas, because all of the atoms naturally maint...
