| 原理： Principle: 静电喷枪是以接地被涂物为正电极，涂料雾化装装置为负电极，并将涂料雾化装置带高负电压，在二极间制成静电界，使雾化涂料粒子带负电，使涂料有效地被吸着于相反电极的被物面上的方法谓之静电涂装。那么为什么将被涂物作为正极而涂料雾化装置作成负极呢?乃因此相反时，其转移为火花放电较难不安全的缘故。 Electrostatic spraying gun is a method of electrostatic coating, in which the ground coating is positive electrode, the coating atomizing device is negative electrode, and the coating atomizing device is high negative voltage. The electrostatic boundary is made between the two poles, so that the atomizing coating particles are negatively charged and the coating is effectively absorbed on the surface of the opposite electrode. So why is it that the coating is used as a positive electrode while the coating atomizer is used as a negative electrode? On the contrary, the transfer is due to the difficulty and insecurity of spark discharge. 为了实施静电涂装，被涂物的接地乃是重要必须条件，那被涂物必须为电气的良导体。木材通常被认为电气不良导体，但其含水率为8%以上时，则可实行静电涂装，而经验上也被确认。 In order to implement electrostatic coating, the grounding of the coating is an important requirement, and the coating must be a good conductor of electricity. Wood is generally considered to be a poor electrical conductor, but when its moisture content is more than 8%, it can be electrostatic coating, and experience has been confirmed. 此乃通常的静电涂装，在正负二极间所流的电流值为20~50微安培(MICRO-AMPERE)，非常小，所以虽然是如木材般，电阻值较大的物体也可以实施静电涂装。 This is the usual electrostatic coating. The current flow between the positive and negative poles is 20-50 microamperes (MICRO-AMPERE), which is very small. Therefore, although it is like wood, objects with high resistance can also be electrostatic coating. |
