It holds the grit on the paper before the adhesive can set.
The term used to describe the build up of electric charge on a non-conductive material due to friction is static electricity.
An electroscope is an instrument used to detect static electricity.
Static electricity attracts dust, soot, and other pollutants form passing air or smoke.

Not sure what you are asking. You have used two fine negative words in the question, so interpretation is difficult."Why can't anything be charged by static electricity?"Static means stationary. Once the static electricity is given the chance to flow, it is dissipated. If I charge myself with static electricity by rubbing my shoes on a synthetic carpet, then I have "trapped" the electricity - it is static or still. When I touch my friend on the ear or hand, the electricity flows to her with a zap and is lost to the ground.Electricity that is generated or from a battery flows continuously in a circuit it is not dissipated.
static electricity is static electricity

Will it is stationary
An electroscope is an instrument used to detect static electricity.
Grounding mats are used when working on electronic components to drain off static electricity. Static electricity develops high voltages (the spark that jumps from your hand to a doorknob in winter is static electricity) and these voltages can damage sensitive electronics.
If you mean the name of the machine used to create static electricity - it's called a 'van de graaff' generator.
electricity is something that causes shocks
Static electricity attracts dust, soot, and other pollutants form passing air or smoke.
coal and static electricity like sparks
Typically, movement is used to obtain electricity of the static or current varieties. Rubbing two dissimilar objects together has been used to create a difference in the distribution of charge (static electricity). Current electricity is typically made by a dynamo or generator: a wire is moved through a magnetic field.

Sandpaper can be made with sand, but carborundum is more common. Glass is made from a mixture including sand.
