Abstract: In order to solve the problems of environment pollution and human resource consumption in traditional wet cleaning process in auto lamps production, a high-voltage Plasma Cleaning Technology (PCT) is presented in this paper. The plasma cleaning system, high voltage AC power and control strategy are realized to develop the plasma cleaning industrial equipment which is used for surface cleaning and activation to promote adhesion between basement and base painting of auto lamps, and the configuration and operation rules are analyzed in detail. According to the established gas discharge model, the PID fuzzy control strategy is achieved to complete automatic control of technology process. The experimental parameters, such as electrical field, gas pressure, and some random factors, are discussed in terms of the curves from practical data. The results show that this design and implementation are feasible in industrial production. After the treatment of PCT to the surface of auto lamps within the automatic equipment, the adhesion between the base material and base painting films is enhanced to a great extent, and the quality and passing rate of production has been greatly improved.

Abstract: Characterization of the interaction between an argon-oxygen post-discharge and hexatriacontane (C36H74) is carried out. Optical emission spectroscopy using the atmospheric band O2 (b1Σg +, v=0
X3Σg −, v’=0) at 760 nm gives simultaneously the evolution of the O(3P) concentration above the surface and the gas temperature by simulation of the rotational spectrum of the transition. Surface reactions contribute to the heating in the sample and to a substantial increase in the gas temperature. Finally, a strong correlation between the time evolutions of the transition intensity and the sample temperature is observed, suggesting that O(3P) is the main reactive species that produces the heating and the chemical changes in the HTC.
