The Benefits and Dangers of Static Electricity

1. Van de Graff Generator
Electric charge obtained by means of an electric charge menggosok.Untuk obtain a very large Van de Graff generator used. Friction between the rubber bands and rubber bands wheel cause players electrically charged. Electric charge is stored on the ball logam.Distribusi have electric charge on the outer surface of a hollow ball.

2. Coagulant Smoke
This tool cleaned ash particles of combustion gases, thereby reducing air pollution. The tool consists of coagulant smoke wire and metal plates, wires made negatively charged, particles of ash as it passes through the wire will be negatively charged. Fabricated metal plate so it will attract positively charged dust particles are negatively charged. Clumps of ash particles that later fall to the bottom cerbong so easy to clean. Coagulant smoke technique is often used in steel mills, cement factories, and chemical industries that spend a lot of smoke.

3. Spray Paint
Granules of aerosol paint becomes charged when rubbing against the mouth of the nozzle and the air. When the objects are painted an opposite charge, then the grain will be attracted to the body paint thing. This method is very effective, efficient, and inexpensive.

4. Copiers
Photocopiers use a different electrical charge attraction. A pattern of positive charge on the plate before, imaged a black field that will be duplicated, attract negatively charged particles of fine black powder called toner, the toner is so negatively charged because it deals with small glass beads in the developer tray. The pattern of toner transferred onto the blank piece of paper and baked on top.

5. Laser Printer
When a positively charged drum rotates, the laser shines across the surface is not charged. Laser will be drawing on paper that are negatively charged. After passing through a rotating drum of paper will pass through the fuser. In the fuser section of this paper will experience warming, which is why the paper was hot when it exits. Laser printers faster, more accurate and more economical.



The dangers of static electricity

1. Lightning
Lightning caused the excess electron cloud on the roof of a building, the building induced a positive charge. Electron jump occurs from the cloud to the roof of the building because of the force of attraction between the two. This event causes the building to avoid being struck by lightning strikes petir.Untuk, the roof of the building is equipped with a lightning arrester petir.Penangkal protect the building as follows:
Electrons jump from cloud to flow through the lightning rod and into the ground. If the air molecules carry positive electrical charges gather around the pointy end of a lightning rod to flow out, then the electric charge induced on the roof of the reduced and partially negative charge on the cloud to be neutral so that minimized the possibility of lightning strikes.

2. Fire Sprinkling
Rounds at the truck runs produce negative charge derived from the friction of the tire with the road. The inside of the metal adjacent to the tire becomes positively charged by induction. This can cause fire. To avoid such events, truck of gasoline or other flammable materials come with a piece of metal at the rear of the car touches the ground. The metal is delivering electrons from the ground to neutralize the positive charge on the metal body car before the fire.

3. Static Electricity Hazards in Aircraft
Aircraft static electricity discharged into all ends of the fuselage structure which is on the roof of the wing and tail shaped like a lightning rod sticking out and elongated shaped metal instrument such that the plane was being protected but can also occur, although only a visual form. This looks visually if the plane is at an altitude of 30,000 feet up and altimeter set to 29.92Hg, free particles in the air and ion2 body aircraft will be exposed to friction and electromagnetic radiation from the HP signal will increase the percentage of radiation in the plane, where the HP signal will be regarded as radiation and is absorbed by the structure of the body and thrown into each end of the fuselage, it could lead to the ends of the electrostatic discharge glow and light up a small crate of lightning. This is not dangerous, but if the frequency of HP equal to the aircraft it can cause aircraft engines to die.

4. Static Electricity Hazards in the Railway
Wheels KA of type ferritic steel, has a very strong magnetic field. The magnetic field is what can lead to vehicle's engine died in the middle of the railroad. Usually the vehicles are easily killed the gasoline-fueled vehicles because gasoline endaraan still using platinum and CDI. If exposed to a magnetic field, then the ignition will be affected so that the engine can die. While diesel is different. In addition to above 12 volts accunya also does not use platinum.

5. Static Electricity Hazards at the pump
Occurred 29 fires where the vehicle entered the nozzle back and touched during refueling from a variety of makes and models. To avoid this you should never re-enter your vehicle while fueling is in progress. If you are forced to re-enter your vehicle while gasoline is pumped, make sure you get out, close the door touching the metal, before you pull the nozzle out. In this way the static electricity from your body will be discharged before you pull out the nozzle.
