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:
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 Slices
The 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 Materials
The 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 Distribution
There are two types of distributions to consider: abrasive particle size distribution and dispersion within the resin filament.
Filament Diameter
Filament diameter includes the size of the filament and its variation (fine or coarse filaments).
Color
Abrasive 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.
Functionality
Different 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 Considerations
Other 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.
