The Molding Study of Polyimide Polishing Film
The polyimide polishing film is a kind of soft polishing films with polyimide substrate and abrasive cement. It isn't replaced by other grinding tool because of its acid resistance, alkali resistance, water-resistance, oil resistance, heat-resistance et al. The paper focuses on ascertaining the minimal substrate thickness of polishing film, selecting molding method and molding technology. Applying the skim coating processes, and using a self-made, film making device, a lab-level, making process of polyimide polishing film is developed, and the polyimide polishing films are made in a lab. Then, study the polishing films form and analyze the molding performances with scanning electron microscope, and get an effect rule of the consistency of polyamides adhesive and abrasive to polyimide polishing films form and the appropriate consistency of polyamides adhesive finally.
