Any object with a charge inside, under normal circumstances, the positive and negative charge quantity is equal to the external does not show the phenomenon of charged, but when two different objects in contact or friction, an object with a negative charge of the electronic It will cross the interface, into another object, the static electricity generated. But also because of their charge generated when the accumulation of high static voltage generated when the two objects with different charge separation or contact when the spark occurs, which is the phenomenon of electrostatic discharge. The main causes of static electricity friction, piezoelectric effect, induction electrification, adsorption, such as live.
In industrial and agricultural production, static electricity has a great effect, such as electrostatic flocking, electrostatic painting, electrostatic pest, etc., and because of the presence of static electricity, often have some hazards, such as electrostatic discharge caused by fire accidents. With the rapid development of petrochemical industry, easy to produce static electricity more and more extensive use of the material, the fire hazard also increased.
Electrostatic hazards are many, its first hazard from the charged body interaction. If the aircraft body and air, water vapor, dust and other particles friction will make the aircraft live, if not take measures, will seriously interfere with the normal operation of aircraft radio equipment, the aircraft into deaf and blind; in the printing plant, The static electricity between the paper will be bonded together, it is difficult to separate, to print trouble; in the pharmaceutical factory. Due to electrostatic attraction of dust, will make the drug can not reach the standard purity; in the TV when the screen surface electrostatic adsorption of dust and oil, the formation of a layer of dust film, the image clarity and brightness reduced; in blended clothes Common but not easy to shoot off the dust, but also static pound the ghost. The second greatest hazard of static electricity is the possibility of an explosion due to the ignition of certain flammable objects by static sparks. Dark night, we take nylon, wool clothes, will issue a spark and "Baba" sound, which is basically harmless to the human body. But in the operating table, in addition to electric spark can cause anesthetic explosion, injury to doctors and patients; in the coal mine, it will cause gas explosion, will lead to death and injury workers, mine scrapped.
The generation of static electricity is inevitable in the production of industrial (related products), and its harm can be attributed to the following two mechanisms: First, the harm caused by electrostatic discharge (ESD). (1) caused by electronic equipment failure or malfunction, resulting in electromagnetic interference. (2) breakdown of integrated circuits and sophisticated electronic components, or to promote the aging components, reducing production yield. (3) high-voltage electrostatic discharge caused by electric shock, endangering personal safety. (4) in a number of inflammable and explosive materials or dust, oil mist production sites can easily cause an explosion and fire.
(1) The electronics industry (related products): Adsorption of dust, resulting in integrated circuits and semiconductor components of pollution, greatly reducing the yield. (2) film and plastic industry (related products): film or film to roll missing; film, CD plastic disc contaminated with dust, affecting quality.
