Technical Answers to Special Brush Abrasive Wire_FAQ

Polishing brush is a special brush, the main material is abrasive wire. Now this brush is widely used in woodworking and furniture industry, steel, iron, non-ferrous metal factories, PCB (electronic circuit board), automobile, motorcycle industry , Textile industry, metal processing industry and many other industries. Introduce some of the material of this brush-abrasive wire. The so-called abrasive filaments refer to nylon filaments added with abrasives such as silicon carbide (SIC) or alumina (AO). Why use nylon 612? Nylon 612 has good corrosion resistance and good bending recovery ability; compared with nylon 6, nylon 66 and nylon 610, nylon 612 has a lower water absorption rate, so that it can still maintain a greater hardness in a humid environment ; In terms of material density, nylon 612 is also relatively low, thus reducing costs; and because nylon 612 is 100% petrochemical polymer, it ensures the consistency of quality. Why use wavy brush filaments? 1. The wave shape can enhance the elasticity of the brush wire and ensure the excellent grinding and polishing effect. 2. Separate the brush filaments from each other and spread them more evenly on the surface of the workpiece to be polished. 3. Enhance the hardness of the brush wire, improve the grinding and polishing efficiency, reduce the possibility of deformation or even breakage of the brush wire due to excessive stress concentration, and ensure the maximum service life of the abrasive disc brush. Can the abrasive wire brush extend the service life of the brush by increasing the height of the brush wire? Can not. Because the life of the brush depends on the production process, the quality of the brush wire and the correct method of use. If you blindly increase the height of the brush wire, the rigidity of the brush wire will not be guaranteed, and the brush wire will fall sideways when working. At this time, the contact surface with the workpiece becomes the vertical surface of the brush wire instead of the end surface, which leads to the middle of the brush wire. It gradually becomes thinner, and finally causes abnormal breakage of the brush filament. It shortens the service life. Welcome to www.mxbrushmachinery.com
