静电喷涂的原理 Principle of electrostatic spraying 静电喷涂是使涂料带上负电荷,并让被涂物接地。当带有负高电压的涂料被喷向被涂物时,由于静电感应,被涂物表面产生正电荷,于是在涂装机器与被涂物之间形成一条条喷涂的轨迹。在静电引力的作用下,涂料附着于被涂物表面,而负电荷通过接地放电。 Electrostatic spraying is to make the coating with negative charge and ground the coated object. When the paint with negative high voltage is sprayed to the coated object, due to electrostatic induction, the surface of the coated object will generate a positive charge, thus forming a spray track between the coating machine and the coated object. Under the action of electrostatic attraction, the coating adheres to the surface of the coating, and the negative charge is discharged through grounding. 静电喷涂的主要优点是静电引力可以提高涂着效率。但需注意的是,专用的机器/喷枪需要采用专用的安全结构和安全措施。 The main advantage of electrostatic spraying is that electrostatic attraction can improve the coating efficiency. However, it should be noted that the special machine / spray gun requires special safety structure and safety measures. |
