| 静电喷枪原理 Principle of electrostatic spray gun 弘大手动液体静电喷枪 Hongda manual liquid electrostatic spray gun 静电喷枪乃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 spray gun is grounded by coating as the positive electrode, paint mist cosmetic device as the negative electrode, and the paint spray device with high negative voltage, electrostatic field in the interelectrode make, make the spray coating of negatively charged particles, the coating effectively sorption in the opposite electrode method of electrostatic coating on the surface of the object. So why would the paint be the anode and the paint atomizer as the negative electrode? In contrast, it is more difficult to transfer to spark discharge than unsafe. 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 carry out electrostatic coating, the grounding of the coating is an important requirement. The coated material must be a good conductor of electric. Wood is generally regarded as a poor electrical conductor, but it can be applied to electrostatic coating when its moisture content is above 8%, and the experience is also 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 usually the electrostatic coating, flow in the plus or minus two electrode current value of 20 ~ 50 amperes (MICRO - AMPERE), very small, so although is like wood, resistance larger objects can also implement electrostatic coating. |
