Grinding, polishing, and dust removal are produced by scraping, grinding, and polishing the surface of the produced brick blank. Therefore, during the process of scraping, grinding, and polishing, the closed air holes on the surface of the brick blank will become open air holes. A large number of fine small cracks will also be generated under the action. This phenomenon is inevitable and unavoidable; open pores and micro cracks are the root cause of pollution. The more open pores and micro cracks on the brick surface, the more the pollution will The more serious, so the polished bricks have been treated with antifouling before leaving the factory, that is, the antifouling wax is applied to the brick surface, and the open air holes and microcracks on the brick surface are filled with the antifouling wax.
However, as far as the current situation of the entire polishing and dust removal industry is concerned, the pollution defect has not been fundamentally resolved. There are many manufacturers complained of pollution, including high-end brands and low-end brands. As the quality control and after-sales staff, the author explores the causes and solutions of soiling from two aspects of product essence and use, with a view to introducing new ideas.
