分析静电组成原理概括其应用技术.docVIP

分析静电组成原理概括其应用技术 物质都是由分子组成，分子是由原子组成，原子中有带负电的电子和带正电荷的质子组成。当两个不同的物体相互接触时就会使得一个物体失去一些电荷如电子转移到另一个物体使其带正电，而另一个体得到一些剩余电子的物体而带负电。若在分离的过程中电荷难以中和，电荷就会积累使物体带上静电。所以在很多运动的物体在与其它物体接触与分离的过程（如摩擦）就会带上静电。固体、液体和气体多会带上静电。如在干燥的季节人体就很容易带上很高的静电而遭受静电电击。 Matter consists of molecules, and molecules are made of atoms, and atoms are negatively charged electrons and positively charged protons. When two different object contact with each other will make one lose some charge such as electron transfer to another object so that it is positively charged, while the other individuals get some surplus electronic objects and negatively charged. If in the process of separation of charge neutralization, charge will accumulate the object with static electricity. So in a lot of movement of objects in contact with other objects and separating process (e.g., friction) will take electrostatic. Solid, liquid and gas would bring static electricity. Such as in dry season human it is easy to bring high electrostatic electrostatic shocks. 　　二、静电的应用技术 Second, the application of electrostatic technology 　　利用静电感应、高压静电场的气体放电等效应和原理，实现多种加工工艺和加工设备。在电力、机械、轻工、纺织、航空航天以及高技术领域有着广泛的应用。 Using electrostatic induction and gas discharge of high-voltage electrostatic field effect and principle, implement a variety of processing technology and processing equipment. In electric power, machinery, light industry, textile, aerospace and high technology has been widely used. 　　（一）静电除尘 (a) electrostatic dust removal 　　静电除尘是利用静电场的作用,使气体中悬浮的尘粒带电而被吸附，并将尘粒从烟气中分离出来而将其去除。这是静电应用的主要方面，可用于各种工厂的烟气除尘。 Electrostatic precipitation is the use of electrostatic field effect, make the gas dust particles suspended in charged by adsorption, and dust particles separated from the flue gas to remove it. This is the main aspect, electrostatic application can be used for various plant flue gas dust removal. 　　（二）静电喷涂 (2) the electrostatic spraying 　　静电喷漆是在高压静电场作用下，使从喷枪喷出来的漆雾带上电荷，这种带电的漆雾，向带异号电荷的工件表面吸附，沉积成均匀的涂膜。静电喷涂的漆液利用率甚高，可达80～90％。主要用于汽车、机械、家用电器等行业。
