Abrasive filament, a plastic monofilament mixed with abrasive particles, is the primary material used in the production of industrial brushes. Here are some main abrasive filament industrial brushes: Abrasive Filament Roller Brush Abrasive Filament Disc Brush Abrasive Filament Strip Brush Abrasive Filamment Tube Brush It is mainly utilized for light grinding, polishing, deburring, and textile brushing. The quality of abrasive filament directly impacts the performance of industrial brushes, which in turn affects the economic benefits for customers. Therefore, selecting the right abrasive filament is crucial. Here are some methods to consider: Types of SlicesThe market offers nylon and polyester slices for making abrasive filament. Polyester abrasive filament is used in specific applications requiring high brush filament hardness, while nylon abrasive filament is widely used. The overall performance of nylon abrasive filament is as follows:PA612 > PA610 > PA1010 > PA6 Types of Abrasive MaterialsThe mainstream abrasives used in abrasive filaments are silicon carbide, aluminum oxide, ceramics, and diamond. Cubic boron nitride is rarely used. The choice of abrasive depends on the customer's specific application. In terms of hardness, the order is as follows:Diamond > Silicon Carbide > Ceramics > Aluminum Oxide Abrasive Particle DistributionThere are two types of distributions to consider: abrasive particle size distribution and dispersion within the resin filament. Abrasive Particle Size Distribution: Abrasive particle size is expressed in mesh size, which can be referenced in national standards. According to these standards, the particle size range is generally wide for a given mesh size, and most abrasive manufacturers can meet these requirements. However, for abrasive filaments, we need a smaller particle size distribution. Dispersion within the Filament: Non-uniform dispersion of abrasives within the filament can lead to localized accumulation and breakage of filaments, resulting in unstable grinding performance. Filament DiameterFilament diameter includes the size of the filament and its variation (fine or coarse filaments). Filament Size: Filament size usually varies based on the changes in abrasive mesh size and the specific application requirements. Generally:Thicker filaments have higher hardness, stronger grinding force, shorter lifespan, and decreased impact resistance (more prone to filament breakage). Variation of Filament Diameter: Due to the presence of a large number of abrasive particles in abrasive filaments, filament breakage is more likely during production. As the abrasive mesh size and filament diameter increase, the probability of filament breakage and variations in filament thickness also increase. This requires optimization of the formula. DuPont's abrasive filaments, for example, are known for their uniform filament diameter due to the use of special formulations. ColorAbrasive filaments are usually the natural color of the abrasive material, which can have slight color variations due to the synthetic nature of the abrasives. Therefore, slight color differences in abrasive filaments are acceptable. However, if the color of the abrasive filaments is too consistent, it is necessary to determine if the color is artificially matched, as this may indicate the use of recycled materials in production. FunctionalityDifferent applications require abrasive filaments with specific functionalities. This depends on the research and development capabilities of the manufacturing company. Functional abrasive filaments available in the market include acid- and alkali-resistant filaments and high-temperature-resistant filaments. Other ConsiderationsOther factors that customers may be concerned about include filament straightness and transparency. These aspects are closely related to the production processes of the manufacturing company. If a company consistently produces filaments with poor straightness or transparency, significant improvements to the equipment or processes may be required, which can be challenging to adjust. Selecting the right abrasive filament for industrial brushes is essential for achieving optimal performance. Considering factors such as filament type, abrasive type, particle distribution, filament diameter, color, functionality, and other relevant aspects will help ensure the desired results in various applications.
