What is static electricity? Static electricity is a kind of charge that is in a static state or does not flow (flowing charge forms an electric current). Static electricity is formed when charges accumulate on an object or surface, and charges are divided into two types: positive charges and negative charges. That is to say, the electrostatic phenomenon is also divided into two types, namely, positive static electricity and negative static electricity. Positive static electricity is formed when positive charges accumulate on an object, and negative static electricity is formed when negative charges accumulate on an object. Some substances can hold their electrons very tightly, and the electrons cannot move easily. We are called insulators, such as plastic, clothes, glass, and dry air. They are all good insulators. On the contrary, it is a conductor, and most substances are good conductors of electricity.
How is static electricity generated? Experiments have shown that all electrical insulators can generate static electricity and accumulate it after intense friction. This is called electrostatic phenomenon or triboelectricity. In frictional electrification, two objects rubbing against each other must be charged with different types of charges at the same time. As for which one has a static charge and which one has a negative charge, it can be determined from the order in the attached table. The order of charging: watch hand, glass, hair, nylon, fur, silk, paper, cotton, hard rubber, polyester, polyvinyl chloride, plastic. The closer to the top, the easier it is to be positively charged when rubbed. The closer to the bottom, the easier it is to be negatively charged when rubbed. Objects can be charged after friction. Positive or negative charges are caused by the fact that the object is an insulator and the generated charge cannot be conducted out and stored. Objects with the same electric charge repel each other, and objects with different electric charges attract each other. The repulsive or attractive force displayed by charged objects is called electric power.
How to prevent static electricity generation or adsorption? There are many ways to eliminate static electricity, such as increasing air humidity to prevent static electricity from occurring. Or add a coating, such as antistatic agent, on the surface of objects prone to static electricity. Among them, the method of applying antistatic agent is the simplest. For example, fibers that were originally unable to be spun can be spun after being treated with antistatic agents, and synthetic fiber shirts make no sound when they are taken off, all of which have achieved good results. Antistatic agents can impart hygroscopicity, lubricity (reduce friction coefficient), and ionicity (itself is ions) to the fiber surface, so the fiber surface becomes an easy conductor, and the charges generated by friction immediately escape to In the distance, electricity is no longer gathering.
What is the connection between antistatic and antielectromagnetic waves? The principle of antistatic is that because it is an easily conductive conductor, it can conduct the generated charge to a distant place and eliminate static electricity. The principle of anti-electromagnetic waves is that it can absorb electromagnetic waves and convert them into trace amounts of heat energy to dissipate. Therefore, both use good conductors as media to convert absorbed static electricity or electromagnetic waves into other energy and release them.
