静电场理论在印刷行业的实际应用

Application of the Electrostatic Field Theory in Printing Industry

以静电场为例,紧扣物理在印刷上的应用,阐述了喷墨打印机、静电植绒印刷和压电喷墨的物理原理,计算了静电复印机硒鼓表面的电荷面密度,给出了电容测油墨量、电容测纸张厚度的方法等.

Taking electrostatic field as an example, this paper focuses on applications of physics in printing. It illustrates the physical principle of ink jet printer, electrostatic flocking printing and piezoelectric ink jetting, calculates the surface charge density of drum surface of electrostatic copier, and gives methods of measuring the amount of ink and thickness of paper through capacitance, etc.
