METHOD OF PROCESSING PLASTIC SURFACE FOR VACUUM EVAPORATION OF METAL AND CERAMIC MEMBRANE

摘要

PURPOSE: A method of processing plastic surface for vacuum evaporation of metal and ceramic membrane is provided. CONSTITUTION: The method of processing plastic surface for vacuum evaporation of metal and ceramic membrane is characterized in that a mold to be used for injection molding of a plastic preform on which metal or ceramic membrane is vacuum deposited is etched by a metal etchant in a thickness of 1 to 1000 μm to produce a plastic preform with an average roughness of 1 to 1000 μm; ceramic particles with a particle size of less than 5 mm is sprayed on a plastic preform on which metal or ceramic membrane is vacuum deposited by sand blasting method to produce a plastic preform with an average roughness of 100 to 2000 μm.
