磨擦生电的现象早被人们发现。不仅如此,两个不同材料的物体互相接触后分离,就会出现正负电荷。磨擦生电不仅和材料有关.还受环境的干燥程度的影响,并且和不同材料之间的磨擦系数以及它们在互相接触后分开的速度有关。在湿度为55％时,人在地毯上行走时产生的静电电压为7,500伏,而当相对湿度下降到40％时为15,000伏,当相对湿度下降到10％时高达35,000伏。在湿度为10％时,把双列直插器件从四苯乙稀海棉橡胶上取下来产生的静电电压高达14,500伏。这样高的静电电压足以毁坏器件。
The phenomenon of friction electricity has long been discovered. Not only that, two different materials contact with each other after the separation, there will be positive and negative charge. Friction power generation is not only material-dependent but also affected by the degree of environmental dryness and is related to the coefficient of friction between different materials and their speed of separation after contact with each other. At 55% humidity, a person produces an electrostatic voltage of 7,500 volts when walking on the carpet and 15,000 volts when the relative humidity drops to 40% and up to 35,000 volts when the relative humidity drops to 10%. At 10% humidity, the dipole is removed from the tetraprene sponge rubber to generate electrostatic voltages of up to 14,500 volts. This high electrostatic voltage is enough to destroy the device.
