Dust Removal – Smokestacks and Air Purifiers

No smoke leaves the chimney Removing Smoke from Power Station Chimnies No smoke leaves the chimney Negative Plate Positive Plate Charge up the Smoke

Dust Removal – Smokestacks and Air Purifiers Opposite Charged plates attract charged and uncharged particles, thereby purifying the air.

Photocopiers - Xerography http://www.youtube.com/watch?v=HFxo4j1EWsA

Photocopiers Copy machines use static to make ink get attracted to the areas where the paper to be copied is darker (i.e. words / images).

Electrostatic Painting http://www.youtube.co m/watch?v=zTwkJBtCc BA&feature=related

Paint is charged Positive with Spray gun Spraying a Car Metal body of the car is submerged in substance gives it a negative charge Paint is charged Positive with Spray gun No paint is wasted as the positive car attracts the negative paint. Ensures a uniform layer. Electrostatic paint job is stronger and lasts longer than if it were just sprayed

Practical Application of Electrostatics: 4. Agriculture Pesticide sprayers charge the pesticides they spray, just like the paint sprayers. This gives a better distribution of the pesticide around the plant’s leaves

Fabric Softeners: Static Cling Fabric softeners work by coating the surface of the cloth fibers with a thin layer of chemicals so that the clothes appear to all be made out of the same material. Like charges repel – no static cling!

Static Cling Window Decals Window decals are made from heavily plasticized vinyl that carries a high static charge. When adhered to a smooth, clean surface (such as glass or a smooth plastic or metal surface), the static cling label adheres easily.
