What are the causes of static electricity?
Electrostatics (focus on how to prevent static electricity) are generally composed of molecules composed of atoms with negatively charged electrons and positively charged protons. Under normal conditions, the number of protons of an atom is the same as the number of electrons, positive and negative, so it shows an uncharged phenomenon. However, the electrons surround the nucleus, and they are out of orbit after an external force, leaving the original atom and invading other atoms B. The A atom has a positive electric phenomenon due to the lack of electron numbers, which is called cation and B atom is increased by the number of electrons. Negative with electricity, called anion.
We all know that friction starts and rarely hears about electricity. In essence, triboelectric charging is a process of contact and separation that causes a positive and negative charge imbalance. Friction is a process of constant contact and separation. Therefore, the triboelectric charging is essentially the contact separation electrification. In daily life, all kinds of objects may generate static electricity due to movement or friction.
In the dry and windy autumn, in daily life, we often encounter this phenomenon: when we undress and sleep at night, the sound of squeaking is often heard in the dark, accompanied by blue light. When the handshake is met, the finger just touches it. The other party will suddenly feel the tingling of the fingertips, which is very shocking. When you comb your hair in the morning, the hair will often float up. The more you mess, the more you will get an electric shock when you pull the door handle and open the faucet. Sound, this is the static electricity that occurs in the human body. The above-mentioned several phenomena are the result of external discharge of static electricity in the body.
When the human body is active, static electricity is generated by rubbing between the skin and the clothes and between the clothes and the clothes. With the increase of household appliances and the wearing of chemical fiber clothes in winter, the static electric charge generated by household appliances will be absorbed and accumulated by the human body. In addition, the indoor walls and floors are mostly insulators and the air is dry, so they are more susceptible to static electricity.
