Research On Plasma Cleaning Methods Of Rubber Mould

As a new cleaning technology, plasma cleaning can meet needs of metal parts cleaning and development trend of cleaning technology, such as high-performance, non-polluting, low energy consumption and etc. Furthermore, plasma cleaning technology has attracted increasing attention of domestic and foreign scholars. Plasma cleaning is a new type of industrial cleaning technology, which uses plasma energy to remove the dirt on the mold surface, reaching the purpose of green cleaning. Mould is an important tool in the rubber vulcanization process, it directly influences the superiority of rubber product external quality even service life and security. So in order to guarantee the rubber product outward appearance quality, it is necessary to scaling mould regular cleaning; therefore, plasma arc cleaning technology will play an important role in mould industry. This paper introduces the plasma arc cleaning technology developing situation of domestic and foreign, the principle of plasma arc cleaning mould, compare the plasma cleaning method with traditional cleaning methods and other new cleaning methods.According to substrate surface for the types of pollutants, as well as the characteristics of distribution, energy coupling mechanism of plasma cleaning speckle particle pollutants and layered dense pollutants have been studied respectively. According to rubber mould substrate surface for the types of pollutants, carried on the finite element hot-stress coupling analysis respectively, using the ANSYS finite element software to simulate the temperature field and stress field on the surface of the plasma cleaning rubber mould Q235, established the 3d coupled model between the plasma and rubber mould, And calculate the surface cleaning force, cleaning strain and surface temperatures of rubber mould. Through the analysis, the influence rule of interface temperature, interface cleaning force and cleaning strain has been revealed, for providing theoretical basis on the choice of parameters during the process of plasma cleaning rubber mould.This paper focus on research the process of plasma cleaning rubber mold technology. Construct the plasma cleaning experimental facility system and establish the evaluation methods of cleaning quality. Through experimentation, the cleaning effect Measured by the Experiments to be identical with effect get through the interface clean force, interface temperature finite element analysis.The plasma cleaning speckle particle pollutants and layered dense pollutants in mould have been studied respectively in this paper. Through ANSYS software simulation results, analyses the different nodes'interface temperature, interface cleaning force and cleaning strain on speckle particle pollutants and layered dense pollutants substrate surface respectively. The effect of process parameters such as plasma arc power, scanning speed, substrate thickness and contaminant thickness on the interface temperature, interface cleaning force and cleaning strain has been revealed again. Plasma cleaning technology as a new process method has a good application prospect and potential predominance especially in mould cleaning field.
