Paper Abstract

This report presented a detailed study on parameters and mechanisms of cleaning rubber layer from a tire mold surface with pulse laser. The results demonstrated that pulse laser can remove rubber layer completely under proper parameters, and there exist cleaning thresholds and damage threshold in laser cleaning. When the laser fluences are in the ranges between the initiated cleaning threshold and complete cleaning threshold, cleaning percentage of the mold surface increases with the increasing of laser fluences. When the laser fluences are in the ranges between complete cleaning threshold and damage threshold, cleaning percentage keeps up 100% and there is no damage on substrate surface. Two mechanisms for laser cleaning rubber layer are suggested: one is the combustion and vaporization of upper rubber layer resulted by high temperature of laser irradiation, the other is particles splattering due to the vibration of deep rubber layer as well as thermal shock action by laser pulse.
